Four Common Car Noises, Their Causes, and How to Fix Them

Eddie spent 35 years in the automotive business with Honda. He is an ASE Certified Master Technician and has bruised knuckles to prove it.

If you own a car, it probably makes noises you can't identify, but would love to fix. Car noises are not just annoying: sometimes they are a warning sign, like the calm before a storm.

Here are the four car noises customers most commonly complain about. Sometimes noises are hard to identify, because a noise travels throughout the vehicle and it is hard to pinpoint where it's coming from. But with a trained ear and some insight, we should be able to figure out what is causing the noise in your car and what you can do to fix it.

Common Car Noises and Their Likely Causes

NoiseMore DetailsLikely CauseFixing It

Clicking noise while turning

Starts faint, gradually becomes more noticeable until very loud

Failed outer CV joint (constant velocity joint) due to torn boot (most likely) or old age

Replace either the whole axle assembly (recommended) or the outer CV joint

Water pump noises

Difficult to diagnose because of water pump's location

Noise usually caused by damage to the bearings in failed water pump

Only cure is replacing it. If possible do it at the same time as a timing belt replacement to cut down on labor costs

Squeak or squeal from an engine belt

Loud, high-pitched squeak or squeal

Belts either need adjustment or replacing

If belts only squeak when damp, they probably just need adjustment. If they squeak constantly, they probably need to be replaced

Exhaust heat shield noises

Rattle that you hear when car is idling

Damaged heat shield

Replace heat shield

Knocking noise from engine

Low knock at idle, noise gets louder as RPM's increase under a load

Piston wrist pin or worn crankshaft bearing. Lack of lubrication/ low engine oil

Tear down engine/diagnose or replace engine

1. Clicking Noise While Turning

Probable Cause: Failed outer CV joint

If your car is making a clicking noise when turning, it is likely you have an outer CV joint (constant velocity joint) that has failed because of a torn boot or old age, most likely a torn boot.

Without going into too much detail about what a CV joint is, I will just give you a basic idea of its function and why it might have failed.

What Are CV Joints?

A CV joint is a set of ball bearings at the inner and outer ends of an axle. It lets a spinning axle bend while it’s still spinning (see this cool animation if you like). A rubber “boot” covers the entire joint and protects it from dirt, debris, and moisture, while holding in the grease that lubricates the ball bearings.

A CV joint lets an axle bend while it is spinning

A CV joint lets an axle bend while it is spinning

Over time, since it’s just rubber, the boot becomes brittle and dry. Eventually it will split open and allow specks of dirt and debris to enter the joint. Once foreign matter mixes with the grease, the damage begins, and it is only a matter of time before the CV joint starts to make a clicking noise when turning. This clicking noise while turning will start out faint, but gradually it will become noticeable and eventually very loud.

How to Fix It

The only way to fix this condition is to replace either the whole axle assembly or the outer CV joint. My professional opinion is that it’s better to replace the entire axle assembly; it’s usually cheaper, even if you can even find the outer joint sold by itself, and it doesn't make much sense to mix old parts with new parts.

Noise From the CV Joint When Turning

2. Water Pump Noises

Probable Cause: Failed water pump

Water pump noises are very difficult to diagnose, because the water pump is generally buried deep in the motor, and the noise will resonate through the engine making it difficult to identify. The water pump on your engine is a thick metal casting containing a pulley, pump fins (a palm-sized propeller to push the water along), and a bearing set. When a water pump fails, the noise is usually caused by damage to the bearings. The video below is a great example of what a noisy water pump sounds like.

How to Verify the Sound Is Coming From Water Pump

If you suspect your water pump is the culprit for the noise in your car, try to locate the water pump on the engine. if you can see the casting of the water pump, you can pinpoint the noise by holding the end of a long screwdriver against the casting and putting the other end of the screwdriver against your ear; if the bearing is bad you will hear the noise through the screwdriver. (See the video below, under “Using a screwdriver like a stethoscope.”)

Replacing It

The only fix for a noisy water pump is to replace it. Because of its location (often under the timing belt cover and bolted to the engine block), an awful lot of parts have to be removed to get to it, so it can take several hundred dollars worth of labor to replace a $50 part.

If it is nearly time for a routine timing belt replacement (every 60,000 to 105,000 miles or so depending on the car), you might want to have that done at the same time as the water pump, because timing belt service is one of the rare occasions when a water pump is easy to get to. In fact dealerships will often want to replace your water pump routinely, whether it’s worn out or not, as part of a timing belt service.

Great Example of a Water Pump Noise

Using a Screwdriver Like a Stethoscope

In the video below, the mechanic uses a screwdriver like a stethoscope, pressing it against the hub of a wheel to listen to a wheel bearing noise.

3. Squeak or Squeal From an Engine Belt

Probable Cause: Dry, cracked, or loose engine belt (just needs to be replaced)

Engine belts can create a loud, high-pitched squeak or squeal that will drive you and your neighbors crazy. Some engine belts only squeak after you go through a large puddle or if there is heavy moisture in the air, and others squeak constantly. If your engine belts squeak only when damp, you probably only need to have the belts adjusted. If your belts squeak constantly, they may be dry, cracked, or loose, and probably need to be replaced.

Does Belt Dressing Work?

Some folks like to use a spray called “belt dressing” to stop the engine belt squeal or squeak. Keep in mind that this spray will not fix anything permanently. It is, however, a great tool for diagnosing the noise and finding out which belt the noise is coming from.

If you have belt dressing, this is what you do: when the engine is running, just spray it on each belt to see which belt starts to quiet down. Inspect your engine belts for cracks, damage, and tension, and replace or adjust them as needed.

How to Use Belt Dressing

4. Exhaust Heat Shield Noises

Probable Cause: Damaged heat shield

A heat shield noise is a type of rattle you hear while your car is idling, or at a specific engine speed or RPM. Heat shields are metal plates along the exhaust system of your car that deflect heat away from the floor of your vehicle and other heat-sensitive components like fuel tanks, wiring, and brake lines.

As the exhaust system ages, sometime the heat shields start to rust at the hold-down points and become loose. If this is your problem, the engine vibrations will cause an awful noise as you’re sitting at a stop light or as your car is idling in the driveway warming up. It sounds like rocks being shaken on a cookie sheet.

How to Fix It

Heat shields can become damaged due to road debris, snow banks, automotive lifts, and just plain old age. In some cases, a damaged heat shield can be removed temporarily without causing any repercussions, but it's best to replace them as soon as possible. An automotive exhaust system can become extremely hot, even 1000o Fahrenheit if you are running your engine at high RPM for long periods, like on the highway.

A Car-Buying Secret

Car noises are inevitable; even new cars have noises that need to be fixed.

Here's a little tip that not too many people know about. When buying a new car, if possible, find out what day it came off the assembly line. Watch out for cars built the day before a holiday, or on a Friday afternoon.

It may sound funny, but humans are building these vehicles, and you know what happens at 5 o'clock on Friday or at closing time the day before a holiday: we rush our work so we can head home to relax or prepare for the holiday. This is not a fact I found in a documentary or anything, it's just my experience. When our shop saw new cars with a lot of little problems, it seemed like they were always built on these out-the-door days.

Ask Someone About Your Noise

There are a lot more car noises than what is outlined here in this article, and it would take a lot more time to explain every one of them, so I only covered the noises my customers complain about the most. Just remember, noise could be a warning sign, so if you have a noise in your car that you are unsure of, bring it to your trustworthy mechanic to have it checked out before it costs you even more money.

If you have a noise in your car and you can't seem to figure it out, ask me about it in the comment box below and I will answer your question as soon as possible.

Questions & Answers

Question: My Honda Accord makes a rattling sound when I come to a stop and when slowly driving away. Sounds like it's coming from under the front of my car. What can it be?

Answer: Have the heat shields on the exhaust checked, they may be rusted and loose.

Question: I have a 97 Jeep Cherokee. it sounded like a tailpipe dragging. Looked under and saw nothing. Started back up, the sound was gone. Drove a few miles and it started back again. Stopped for a minute and it was gone again. It's parked at home now. Can you help?

Answer: It sounds like one of your rotor backing plates is rusted off and is rubbing against the rotor sometimes. I recommend checking all your rotor backing plates first. Check out this video https://youtu.be/Ah62R9pEwg0

Question: I have a 04 Impala LS 3.8lt auto, it has developed front end noise on the passenger side, only when turning right. It sounds like a metal clattering noise to me. Turning the s-wheel to right while driving or bumping the s-wheel to right, bing bing bing, like broken spokes hitting metal, is my best guess to describe the sound. Replaced front struts, cv axles, motor mounts, but still have the same noise. Do you have any advice?

Answer: Are you sure this noise is not coming from the brake area? It is possible your rotor backing plate is touching the rotor or maybe there is a rock stuck between the backing plate and rotor.

Question: I am hearing a faint whining noise when my car is stopped. I don't hear the sound as I am coming to a stop; I only hear it when fully stopped with my foot on the brake. Once I take my foot off the brake and accelerate, it goes away. What could be causing it?

Answer: I recommend checking the power steering fluid level; it sounds like it may be low.

Question: My jeep patriot is making a low noise around 30mph. It almost sounds like the noise a ceiling fan makes. It doesn't do it while I'm sitting at a light or when I'm going any faster than 30 mph. Any Ideas?

Answer: Possible wheel bearing or tire noise? Check the tire wear first, make sure it's even.

Question: I just got a 2015 Toyota Camry. It idles quietly, and can drive under 45 mph. I don't hear any sounds until I take it close to 50 mph and let off the gas pedal, in which case I will hear a knocking sound. The sound will cease when I slow down, and I won't hear it until I go around 50 mph again. There are no warning lights on the car, nor is there a noise until I get over 50 mph. What is happening, and what should I do?

Answer: It sounds like maybe a CV joint. You should have a 5/50 powertrain warranty, so call the dealer and ask.

Question: Why does my Honda Odyssey front end make an occasional moaning sound at low speeds?

Answer: There are a lot of reasons for a moaning sound in your Odyssey, but it may not be coming from the front end. Here are a few examples of a moaning sound from an Odyssey: struts, water pump, power steering pump, alternator, AC compressor, suspension bushings, ball joint moan, etc...

Question: My car just started making a noise like drums in the area under the dash. I have a Pontiac Vibe. Any idea what it might be?

Answer: If you only hear it when the fan is on, you could have some debris stuck in the blower motor.

Question: My Toyota Corolla 2015 is making a soft thumping and soft banging noise. It sounds like it's coming from one of the tires. What could it be?

Answer: If you hear the noise when braking it's possible the rotors have pad impressions caused by rust. If the noise is heard while driving without applying the brakes, it's possible your tires are worn or uneven and are causing the noise.

Question: My 2012 Jeep Grand Cherokee makes a weird whining noise when sitting in traffic with my foot on the brake. If I put it in park, it only seems to do it when the vehicle is warmed up. It also made the noise when I was backing into my carport when turning the steering wheel. The noise only lasts for a few seconds then goes away and is fine when driving any ideas?

Answer: I recommend checking the power steering fluid reservoir; it sounds like you may be low on fluid. If so, have the steering system checked for leaks.

Question: I have a loud vibration/rattle coming from my car; it does this as I’m accelerating and also at idle, but obviously goes away if I rev the car. My exhaust is solid, and I have no lights on my dash so concerned as to what it could be and how to fix this?

Answer: Exhaust heat shields can appear to be solid, but when examined closely you may find a corner near the stay rusted and completely disconnected. I recommend having a mechanic place the car on a lift and take a look underneath.

Question: My car starts rattling when accelerating uphill, but taking off from idle blows a grey smoke. What could be the issue?

Answer: It sounds like you're describing a ping noise from the engine, and you're burning oil. You should have the ignition timing checked.

Question: My 181 Golf diesel engine continues to run after the engine is switched off, do you know why?

Answer: Have the engine timing checked, that would be the most common reason for this to happen.

Question: Why does my 2009 Chevy Traverse make a rattling noise when stopped at a light? It seems to be coming from the middle console.

Answer: If the noise is coming from under the car, check the exhaust heat shields, sometimes they become rusted and loose, then start to rattle at idle.

Question: My 2016 Ford Edge makes a single clunking/clicking low pitched dumb short noise when moderate to hard braking is applied, right before or almost when the vehicle is coming to a complete stop. What could this be?

Answer: I'm not sure there is such a thing as pad shift, but this only happens the first time you hit the brakes moving in a forward or backward direction and you only hear it once when moving in the same direction, you will only hear it again when going in the opposite direction and hitting the brakes once.

Question: My car is a 2003 equinox. Everytime I come to a complete stop it makes a clunk noise. What does that mean?

Answer: It's possible you have a worn or loose suspension component. I recommend having it inspected to locate the noisy component.

Question: My 2004 Hyundai Sonata has been making a weird thudding noise. It seems to come from my right rear tire. It only happens when I seem to hit a rough spot on the road, and goes away when I slow down. Any ideas of what it could be?

Answer: I recommend having the shocks/struts checked, it's possible one is leaking and causing the noise.

Question: When the engine of my Fiat Punto is hot and running at 2000 rpm, it sounds like a rattle or some kind of rumble coming from the top of the engine. What could this be? It only does it when the car is hot.

Answer: It could be that the oil level is too low, or that it is in need of an oil change.

Question: How can I correct rear wheel noise on a Honda CR-V ?

Answer: I think what you are hearing is a loud rubbing noise on tight turns. If this is true, you need to replace the rear differential fluid with genuine Honda differential fluid for your year make and model. Sometimes we need to drive the vehicle for a week then change the fluid a second time.

Question: My 2013 G37x started making a low humming noise that sounded like it was coming from the left rear wheel. It starts when I get to about 40 mph and I can only hear it when the back rear window is open. The car only has 26k miles on it. What might it be?

Answer: If you hear it with the window open, most likely it uneven tire wear.

Question: I have a 92 Jeep Wrangler with a manual transmission. Lately, it has been riding very hard. It feels like its pulling from the back, I think. It drives super slow when I’m between about 15mph to 40 mph. After 40 mph, it resumes driving smoothly; well as smoothly as you might expect of a jeep. Do you have any ideas?

Answer: It sounds like your engine is lacking power. Spark plug wires can have that effect on an engine, it will sputter and choke until you get up to speed and will smooth out when coasting, but as soon as you put a load on the engine, it will do it again. Check your wires first.

Question: My 2011 Mitsubishi Galant is making a whining sound on the passenger side front end. What could this be?

Answer: If the whining sound is heard above 25mph and gets louder with speed, it possible that you're hearing either a wheel bearing starting to fail, or the tread is starting to wear uneven. I recommend checking the tire tread first, and if everything looks OK, have the wheel bearings checked.

Question: I hear a high pitched whistling noise coming from my front left tire and under my truck. I have a 05 Silverado 2500HD. It does it both driving and idling. What could it be?

Answer: It could be a vacuum leak of some sort. You'll need to pinpoint the location of the noise and see if you have any disconnected or broken vacuum lines.

Question: My car was making a whining noise, but it has stopped. What could it have been?

Answer: I recommend checking your power steering fluid level.

Question: After turning the engine off of my 2014 Avalon, I can hear a clicking noise coming from the rear part of the car. What do you think it is?

Answer: It's either your exhaust pipes cooling down or the fuel tank expanding and contracting.

Question: I was just turning into my complex when I heard a low scraping noise from the rear right side of my vehicle. Do you know what this may be?

Answer: Check out my video on this type of noise, this may help: https://youtu.be/HR8UbHpBfmU.

Question: My 2002 Sebring is making a knocking and squeaking noise on the passenger rear side. At first, I thought something was rattling around in the trunk, so I emptied it. But it's still there and getting worse every day. It is mostly during in-town driving; when I get on the interstate, it seems to lessen. What could it be? Is it safe to drive?

Answer: I recommend checking your shocks first. One could be blown out and causing this type of noise. If they are not leaking, check to make sure both top and bottom of each shock is tight. Try bouncing the car in the driveway to see if you can reproduce the noise, and have a partner see if they can locate the noise if it can be replicated while bouncing the car.

Hi Esko,

It's possible you have a loose heat shield on the exhaust system and it's is causing the noise. The shaking at idle could be a failing motor mount so it's a good idea to at least have it check out for peace of mind :) Let e know what you find or if you have more questions, thanks.

Eddie Carrara (author) from New Hampshire on August 31, 2020:

Hi Mark,

Check all the plastic shields under the car and in the fenders to be sure all are secure. Sometimes if any of these shields are loose, the 50mph winds will pull on them and cause them to drag against the tires or ground while driving. Let me know if this helps, and keep me posted on what you find, thanks.

Esko Elias on August 31, 2020:

My 2005 Nissan Sentra has been shaking vigorously while idling. But, yesterday I accidentally cranked it after the car was already on and now a rattling metallic noise is coming out from under the hood when idling when idling as well. What do you think I should be worried about and is it a big deal?

Mark P Cunningham on August 30, 2020:

Eddie Carrara (author) from New Hampshire on August 29, 2020:

Hi Lisa,

How does the tire tread look, is it smooth or bumpy? Run you hand along the tread surface to identify any uneven wear. Did the noise gradually get worse or did this happen suddenly?

Mathabang on August 20, 2020:

My Honda CRV-2007 has a noise on the left side infront when moving, it is as if the window is opened yet it is not, I checked AC, normally off and the sound is still there, like there is a lot of wind outside.

Eddie Carrara (author) from New Hampshire on August 15, 2020:

Hi Clive,

I know this is a silly question, but did anyone check the brakes? Do you hear it only going over bumps? What type of bump, like a speed bump or potholes in the road? Can you reproduce the noise by bouncing the car when it's parked? Let me know, thanks.

CLIVE SIMPSON on August 14, 2020:

I have a noise on front passenger side of a 2018 Ford Mustang. Occurs going over bumps and increases volume and regularity in hot weather. Disappears for a day after driving through rain water on the road. Its a high pitched short squeak/ringing noise. I was told it was probably a squeaky rubber bush in the suspension, so I sprayed all joints with silicon lube, but the noise is still there. Also couldnt find any issues with loose suspension parts. My Ford dealer also couldnt find anything wrong. Losing hope that I will ever get this resolved.

Seb on June 30, 2020:


I have a Nissan Dualis AWD. It has a rattle that comes randomly when car slows down or goes up hill. Check with mechanics, engine ok, changed gasket from exhaust pipe But rattle still there. The sound is difficult to pinpoint. Looks like comes under the hood or inside cabin.

Elyssa on June 29, 2020:

Hi Jerri,

Is there any way you can take a video of the noise and upload it to YouTube then send me the link? I would like to hear it and also visually see when it's happening. Let me know, thanks.

Jerri Long on May 28, 2020:

My 2003 GMC Yukon xl is making a clacking noise when you crank it and gets louder as you exccelerate . We have checked belts , water pumps etc.everything us good and No warning lights are on the dash...this is a very annoying sound but no one can figure the sound out.

Eddie Carrara (author) from New Hampshire on May 27, 2020:

Hi Cindy,

There is no way to tell when an alternator is going to fail so if they told you that, they're lying. Yes, I think they may have left a splash shield loose and that's what you're hearing. I recommend you bring it back so they can double-check their work. Let me know what they find, thanks.

Cindy on May 26, 2020:

2002 toy 4 runner 4x4. Went into volvoline has 3 belts replaced cuz battery light came on and they were due changing. Come to discover alternate is fixing to go out. But now I here like a metal flag flappy sound at decreasing speeds when I hit the breaks. Wondering if they left something loose or possibly damaged heat shield?

Eddie Carrara (author) from New Hampshire on May 24, 2020:


It sounds like you may have had some damage to the front bumper? I recommend you check the undercarriage engine splash shield for any loose or missing clips to start. If you have plastic hubcaps on your wheels, make sure they are tight and don't rattle. Let me know if this helps or maybe you could send me a video of the noise?

AP Winter on May 23, 2020:

Hi Eddie - My Pontiac Vibe had a low rattle that sounds like it is coming from the front drivers side in engine box or under dash (deep under like under the car). Only happens at lower to medium speeds on rough surface. No noise on smooth surface. I have had trim fixed on bumper, new wheel well liners, checked all plastic under hood, etc. Thoughts? Thanks in advance.

Eddie Carrara (author) from New Hampshire on May 16, 2020:

Hi Mo,

When do you hear the bang? when you put it in gear, driving, turning, what speed, braking?

If the car sits for long periods of time it's possible you have a lot of rust built up on the rotors which can cause a grinding noise and a vibration. Let me know when the car make noise Mo, thanks.

Mo on May 16, 2020:

I have an Honda Accord that makes a loud bang sound when I move it after it’s been parked for a while. Why is that?

It also makes a grinding sound & vibrates when driving. Please what could it be?

Eddie Carrara (author) from New Hampshire on May 08, 2020:

Hi Greg,

First, does your noise sound like any of them in the video? This is a weird noise because it disappears when you put it in neutral which leads me to believe that it may be inside the transmission, but what if you just coast and leave it in drive, does the noise disappear? Is there any way you can upload a video of the noise to YouTube and send me the link or just send me the video?

Gregory Bratten on May 05, 2020:

My car is front wheel drive l dont have a drive shaft. Both front axles have been replaced along with all four wheel bearings

Eddie Carrara (author) from New Hampshire on May 05, 2020:

Hi Greg,

I think what you're hearing is a driveshaft carrier bearing noise. I created a video with examples of both wheel bearing and driveshaft bearing noises so maybe this will help you out with your diagnosis. Let me know, thanks. https://youtu.be/5q7Dg_hyX8M

Eddie Carrara (author) from New Hampshire on May 05, 2020:

Hi Jacinda,

It sounds like you may have an exhaust leak at either a flex joint or at a gasket point. You'll need to have a mechanic raise it on a car lift to inspect the cause. Let me know what you find, thanks.

Hi Monneta,

It sounds like you heard whistling from the cooling system building pressure and letting go, like a teapot boiling water. The coolant must be very low because of a leak or you have something else wrong.

Monneta on May 02, 2020:

I heard a loud whistling noise that was heard a good minute then engine idle overheating came in the screen. What can it be

Eddie Carrara (author) from New Hampshire on April 23, 2020:

Hi Rose,

There are a lot of things that can cause this noise. I recommend you start by having the exhaust and the exhaust support hangers checked because the exhaust moves a lot with engine vibrations and if a support hanger is broken it could cause the noise. If everything looks ok, Have the motor mounts checked. This is the third motor and it's possible either a motor mount is broken or the mechanic may have not tightened one of them completely. Let me know what you find or if you have more questions.

Rose on April 22, 2020:

I turned my car off and heard a noise like bump bump hard to discribe like I went over a speed bump no light came on on the dash. But I’m on my 3 motor after that my car seems to run fine someone said maybe wires

Hi Elyssa,

I recommend you have the brake pads checked, it sounds like the brake pads are worn out. If the brake line blew the brake pedal would sink to the floor and it would be very difficult to stop the car. Let me know how your brake pads look and make sure you look at both inner and outer pads, the inner is usually the culprit.

Elyssa on April 08, 2020:

2012 CRV with 113 k miles. Started making a metallic sqealing sound in the driver's side rear yesterday afternoon. I was at a stop sign last night and when i started to go again I heard a pshhhh noise it sounded like my brake line broke or blew . And a metallic grinding noise on and off as my wheels were turning. I parked the car and let it sit over night. I checked the brake lines on the back tires and the front and they were fine then I drove it around and there is no more noises I parked it and I let it sit for another 2 hours then when I started driving and it sound like I was dragging something metal from the back what can it be?

Eddie Carrara (author) from New Hampshire on April 06, 2020:

Hi Larry,

If you hear the noise above 20 mph it's most likely a wheel bearing noise but it's not a bad idea to check the tire tread to be sure the tires are not chopped or worn uneven. If you what to leave me more details about the noise I may have a more definitive answer to what may be the problem. Let me know, thanks.

I have a 2013 subraru lagacy and theres a whinning humming noise when driving

Eddie Carrara (author) from New Hampshire on March 28, 2020:

Hi Israel,

Is there any way you could send me a video of the noise, you could upload it to YouTube and then send me the link by clicking the "Contact Author" link next to my profile photo. Let me know, thanks.

Israel on March 26, 2020:

I have a 2012 Toyota Camry SE makes noise on passenger side I took the cover off still makes noise is metal-to-metal help me find a problem check motor mounts check everything seems fine

Eddie Carrara (author) from New Hampshire on March 05, 2020:

Hi Rob,

It sounds like a wheel bearing to me and I know you changed out all of them but maybe one was damaged during the installation? The best way to diagnose this issue is to have a mechanic run the vehicle in drive while on the lift so they can check each wheel bearing with a stethoscope, they can also double-check the center carrier bearing while it's in the air. Let me know if this helps, thanks.

Rob Murphy on March 04, 2020:

Hi eddie, i have a mk3 honda crv jan 2008, 2.2 cdti, between 55 -60 , i get a humming vibration noise, much like a wheel bearing or tyre which ive changed them all, new wheels and tyres even intermediate drive shaft bearing, it goes after 60 mph, and it goes if i turn the steering left or right, i can feel it thru the steering wheel, its driving me insane , thanks

Eddie Carrara (author) from New Hampshire on March 02, 2020:

Hi Sheila,

I think I have most of the Granite buried in my yard, I can't dig a hole without hitting a rock lol. It's good that you replaced the serpentine belt because it was due and they can definitely cause noises if it is in poor condition. If the noise comes back I recommend you have the exhaust inspected for any loose or rusted heat shields, that is another common issue here in the Granite State. Keep me posted on what happens and if we need to dig a little deeper :)

Sheila on February 29, 2020:

Hi, Eddie - you are awesome for writing me back. I have started emptying out everything in the vehicle. It has gone away so far. I also had the serpentine belt replaced, since it was due anyway and I read that it might be caused by that as well. It is a great service that you provide - proud to have you as a fellow Granite Stater!

Eddie Carrara (author) from New Hampshire on February 28, 2020:

Hi Sheila,

If the noise is intermittent I recommend you remove everything in the vehicle that could make noise, I know it sounds like a huge task but it may be one of your personal items in the glove box, door pocket, sunglass holder, etc, making the noise and the mechanic does usually need to remove the glove box to remove the cabin air filter and that's why the noise may have changed. I have seen garage door openers, E-Z passes, zippers on customer jackets, etc make various noises so you have to do a process of elimination and verify if the noise is still there and it is coming from the vehicle. My favorite story was the customer's zipper on his jacket, we could hear the noise while driving and when I grabbed his zipper the noise stopped lol so you just never know lol. Let me know if this helps and let me know what you find.

Sheila on February 27, 2020:

it is inside the vehicle.

Eddie Carrara (author) from New Hampshire on February 25, 2020:

Hi Sheila,

Is the noise inside or outside the vehicle?

Sheila on February 23, 2020:

Just a follow up - I have a 2013 Honda Civic. The rattling is like tiny bells or something - hard to explain - it happens when idling and driving. It happened some time ago (months to years) and then went away. Now it is back. I thought maybe when they replaced the cabin filters or something (when this first started a long time ago) they loosened the dash, but then it went away and now it is back. It's very strange. Hope you can help. Thank you.

Sheila on February 22, 2020:

I have a rattling noise inside my car - it's not outside, it is localized to the front interior. It comes and go. I've opened and closed the glove compartment, checked if my keys are hitting metal, and I can't find anything.

Eddie Carrara (author) from New Hampshire on February 21, 2020:

Hi Kathy,

I recommend you start by checking the exhaust heat shields for any that may be loose or rusted. Let me know what you find, thanks.

Kathy on February 20, 2020:

My Honda HRV makes a rattling noise when I am idling at a stop sign as soon as I give it gas it stops or if it’s in park it doesn’t do it so much or even neutral what could that be

JIM MOSS on February 06, 2020:

Thanks Eddie, I will try this time permitting It may be some time before I get back to you.

Eddie Carrara (author) from New Hampshire on February 06, 2020:

Hi Jim,

If you're hearing the pump running and the brake pedal is kicking back only on turns I recommend you check a couple of things. Inspect all pick-up rings if this is the type of system that has the rings on the axles, also inspect all connectors for any corrosion at the terminals and the wire harness for any abnormalities. The other problem area would be the axles themselves. inspect the axle nut torque to be sure they are not moving in the hub and the wheel bearings are tight. Let me know if this helps.

JIM MOSS on February 05, 2020:

Thank you Eddie, you are right but it is only occurring on turning the steering wheel

what would you suggest I do about it?

Eddie Carrara (author) from New Hampshire on February 03, 2020:

Hi Jim,

When the ABS pump is running, you can hear a dull thudding noise and also feel a kickback in the brake pedal, once you take your foot off the brake pedal the noise will stop.

Jim Moss on February 01, 2020:

Dull thudding noise and slight bump in front end at slow speed with weight on front end and turning. Could it be ABS malfunction?

Eddie Carrara (author) from New Hampshire on December 24, 2019:

Hi Tony,

Check your exhaust system clearance and heat shields, make sure no part is touching the floor and all shields are tight. If you live in a snowy area, make sure there is no ice up against the floorboards. Let me know if this helps, if not we can check a few more things, maybe you can send me a video of the noise or something.

Eddie Carrara (author) from New Hampshire on December 24, 2019:

Hi Tuliraba,

I recommend you check the serpentine belt and tensioner, they are known for making a rattling noise.

Tony on December 24, 2019:

I have 2016 Mustang GT and when get to 60 to 65 mph I hear rattling sound from the driver's side floorboard. What can that be?

Tuliraba Mark Joseph on December 23, 2019:

I have a Honda Elysion 2.4 it has a rattle sound in the engine area when idling and driving. What could this be ? This started after a long distance drive at high speed.

Patricia on December 21, 2019:

I started my 1999 Buick. I was letting

It warm up. And heard a bang. What is the problem. Also when I drive my car weeks ago it stopped running while driving. What is the problem

Val on December 19, 2019:

AUDI A4 DIESEL 2002 was in perfect nick. Had new alternator and belt, car fine. A day later, I start the engine and turn steering wheel in a hard left turn to drive away and a sound like rubbing, squealing, then the engine starts to rattle like hell, I drove 2 hundred yards, pulled up, and before I could oprn the hood, the engine reverted back to its normal sound. Has the mechanic aligned the belt and does my water coolant need to be checked. Am very worried.

Eddie Carrara (author) from New Hampshire on December 17, 2019:

Hi Elizabeth,

Sometimes the exhaust system has a double-lined pipe and the inner pipe become loose or detached causing a rattle, do you think this noise could sound like this issue?

Elizabeth Schaeffer on December 16, 2019:

2008 Chrysler town & country van, 135000 miles. Loud rattling constant noise when going uphill until I give it more gas. Then it stops. Always happens between 45 and 60 mph when going uphill. Occasionally happens at lower speeds when going up hill. Spent 3 hours at my son's auto repair shop. They checked everything they knew to check including the transmission. No luck. One of the technicians rode with me so he knows the sound. It cannot be duplicated on the flat. Any ideas before I take it to a Chrysler dealer?

Rosa on December 08, 2019:

What could be the problem with my CRVHonda 2002? When I start it there is loud weird sound. I don't where it is coming from. So I have to turn it off. Is it an low oil problem?

Christian on November 23, 2019:

My 2005 Dodge Ram 3500 makes a rattling noise in the cabin when I start to accelerate slowly but once I’m accelerated faster it goes away and the sound is coming from the steering column. Can u please help me

Eddie Carrara (author) from New Hampshire on November 17, 2019:

Hi Violet,

Make sure the air cleaner housing cover and tube are correctly installed and I also recommend you remove the mass-airflow sensor again and blow it out with light air pressure like from a can of air for your computer keyboard. The mass-airflow sensor is very sensitive and all it takes is a human hair across the sensor to give a false reading.

Violet on November 15, 2019:

Hi Eddie..My service engine light came out.The code was for a bad Max airflow sensor.Replaced it and knocking and shuddering atill happening on passenger side.Please help me.I have spent so much money already and everything thats replaced doesnt change it

Eddie Carrara (author) from New Hampshire on November 06, 2019:

Hi Abdul.

I think you have two separate problems. I recommend you have the front suspension checked for any loose or worn parts and also have the exhaust heatshields checked for any loose or rusted parts.

Eddie Carrara (author) from New Hampshire on November 06, 2019:

Hi Michael,

I recommend you check the external engine belt tensioner first, if it's ok,we'll have to dig deeper.

Eddie Carrara (author) from New Hampshire on November 06, 2019:

Hi Danielle,

I recommend you check all the exhaust heat shields to be sure they are tight, also check all plastic splash shields around the wheels and under the engine, if any of them are loose they will flap in the wind when driving down the road. Let me know you find :)

Eddie Carrara (author) from New Hampshire on November 06, 2019:

Hi Bradley,

It may have something to do with the emission system purging fuel vapors since you just filled up the tank. Is the noise coming from the front of the vehicle or rear?

Bradley W on November 04, 2019:

Hi Eddie.

I drive a 2011 Chrysler Town & Country. Approx 62,000 miles. Drove it for about 30 minutes including tank fill-up tonight, parked in the garage & didn't notice any problems. Went to put something in the garage approx 2 hrs after parking it, & noticed a noise coming from the underside of the van. The best way to describe it is air coming through a vent (like heat in your house coming through the floor or ceiling register). I thought it was some sort of fan running, but checked the engine & no noises from the engine. It's enough of a running/fan-type, constant whooshing-ish noise that I ruled out leaking tires. I have no idea what this noise could be or why it's happening as I've never heard it before & owned the vehicle for approx 3-4 yrs (since about 30k miles). I'm hoping you can help identify what that noise could be or give me an idea how to diagnose. Thank you for your assistance!

Danielle on November 04, 2019:

I have a 2007 Trailblazer SS and at about 20 mph, there is a rattle that almost sounds like rattling aluminum cans dragging. It is so annoying, but only happens when I reach 20 mph or higher.

Michael on November 01, 2019:

I have murano 2005, the car suddenly developed a fault of knocing sound after few minutes of drive both while idling and on speed . The car does mot lose power while making the noise but the engibe turns off intermittently. Ive done oil change yet still the same . The sound does not come at staring in the morning

Abdul on November 01, 2019:


I got Toyota Estima hybrid 2008

When I’m driving on rough road or going through speed humps, I can hear clicking or grinding sounds And Steering wheel shakes. On normal road drives fine

Eddie Carrara (author) from New Hampshire on November 01, 2019:

Hi Jenn,

So does this happen when you're starting the truck or when you're shutting it off after driving for a while? Is the engine running on after the key is turned off and then eventually stalls out? Let me know, thanks.

Jennifer Guerra on October 29, 2019:

I have a 1995 chevy blazer 4x4 and a couple of days ago my truck start to make a grind nosie when i turn my truck off and it tries to turn it self back on i bought a starter cuz that what i though was wrong with it but with the new one it still makes that noise what do you think what could wrong can you help me oit

Eddie Carrara (author) from New Hampshire on October 24, 2019:

Hi Tiffany,

Wheel bearing noise is very consistent, maybe one of the rotor backing plates is to close to the rotor? Without hearing the noise it's only a guess. Can you take a video, upload it to YouTube and send me the link?

Tiffany on October 22, 2019:

My 2017 Toyota 4 runner has a noise from driver side like a groaning noise , it’s louder on gravel and when it rains , it’s not consistent . We changed the wheel barren and struct what can it be

Eddie Carrara (author) from New Hampshire on October 22, 2019:

Hi Vince,

Is the noise coming from the engine or do you think it's coming from the vehicle suspension?

Eddie Carrara (author) from New Hampshire on October 22, 2019:

Hi Kimber629,

He may not be a car guy but ignoring a serious problem will not make it go away. It's possible a caliper was freezing up causing the noise but without hearing it I'm just guessing. Let me know if you figured it out.

Eddie Carrara (author) from New Hampshire on October 22, 2019:

Hi Kathu,

Your vehicle is still under warranty, if you're worried about the noise, bring it into the dealer and have them check it. out

Kimber629 on October 21, 2019:

On our 2015 Kia Optima, we have been hearing a noise like loose gravel ticking around on the drivers side in the rear. We were headed home on I-35 from OK and we heard a LOUD thud from back there and now the gravel sound is louder ( hubby refuses to stop on the interstate to check it out! He’s NOT a car guy!). He SAYS he didn’t see anything fall off. ?? Thanks!!!

vince on October 19, 2019:

when driving my 2009 hyundai accent, i hear a tapping noise. but when i let off the gas petal and let it coast it stops making noise.

Eddie Carrara (author) from New Hampshire on October 15, 2019:

Hi Brenda,

I recommend you check the power steering fluid level (or is it electric PS? ) to start. Let me know what you find, thanks.

Eddie Carrara (author) from New Hampshire on October 15, 2019:

Check the exhaust heat shields for any small pebbles or loose hardware.

I on October 12, 2019:

I hear a rattling sound at times when i turn 2016 malibu off

Brenda on October 12, 2019:

I have a 2012 Prius when I turn the steering wheel to the left and the right it makes a noise kind of a grinding noise we check to see if something was rubbing nothing worse it only does it when you’re driving slower and you’re turning what could it be

Eddie Carrara (author) from New Hampshire on October 10, 2019:

OK Rob,

Let me know if I can help in any other way.

Eddie Carrara (author) from New Hampshire on October 10, 2019:

Hi Thullani,

What is the year, make, model, and mileage? Where is the smoke coming from, the vents? Is it visible? Is your AC on and is it very humid?

Thulani on October 10, 2019:

Hi Eddy why is smoke coming inside of my car when driving especially when climbing

Rob on October 07, 2019:

Hi Eddie,

Unfortunately, I do not have the means to upload to Youtube.

I did notice that after driving in the rain the squeal disappeared. It came back today. I am guessing some rubber component or such must be dried out. I will inspect the suspension and stearing components more closely within the next few days.

Eddie Carrara (author) from New Hampshire on October 03, 2019:

Hi Rob,

Is there any way you could take a video of the noise, upload it to YouTube and send me the link, my contact email is located up by my picture on the top of the page. Let me know, thanks.

Rob on October 03, 2019:

Hi Eddie,

The power steering fluid is at it's proper level and clean. I checked for the tire rubbing against the body or suspension, steering component. No indication of any rubbing found. It only happens when turning the wheel all the way left while moving slowly. It does seem to be increasing in volume.

As a side note, the front rotors and brake pads were replaced a month ago. The van tracks true and stops fine. The fact that the volume is increasing concerns me more than the squeal itself.

Eddie Carrara (author) from New Hampshire on October 02, 2019:

Hi Herb,

You'll need to replace the bearing, but if you have never done it before, it's a good idea to have someone who's knowledgable help you or have it replaced professionally.
