Prius (2010-12) :: Clattering Noise Coming From Suspension
Aug 10, 2010
Since new my Prius V has had a metallic clattering sound that comes from underneath the car. This can be replicated when driving over lane divider dots on a quiet street with the windows down. To investigate, I put the car on ramps and looked around; I was almost certain the sound was coming from a thin aluminum heat shield that is just behind the engine. Tapping this shield made a similar sound to what I heard coming from under the car while driving over bumps and such. The shield is poorly attached with those "fun" push pin fasteners that seem to be liberally deployed all over the undercarriage. I decided to re-attach the shield with a judicious circular application of silicone under each of the holes in the shield and let it dry. The clattering sound I heard previously when tapping the shield was gone. Out for a test drive and still there!
I just had the first service done, and of course the tech couldn't hear it on his test drive. Unfortunately I was pressed for time, so I wasn't able to take a test drive with the tech. I will drive the tech around next time and demonstrate it.

So on my 2003 F250 SCLB 4x4, I I was driving 70 or 80 miles to Huron in Ohio, to pick up a boat for a buddy with my truck. On the way up I heard a new clattering noise coming from the suspension or drive train, and we couldn't figure out what it was. After picking up the boat and coming back home without a problem, I looked under the truck and couldn't see any U-joints loose, But I saw that my right rear backing plate was disintegrated and gone. I took the truck to the shop and they said that the noise I'm hearing is the guts of the emergency brake pads and pins bouncing around in there when I drive and that my rear wheel could lock up at any time.

I have a 2012 Elantra with 25k miles and after the car sits for about 2 hours, there is a loud clattering noise coming from the exhaust when running. Mainly when I first start it up and take off down the road. After about 2 mins of driving, it's a lot quieter.
Anyways, I raised it up a bit today and everything looks normal, but using a mallet, I knocked all over the exhaust a bit and it all seems to make a rattle noise. Mine started about 1 month ago.

Parked Prius making awful sound from brakes. Could it be Suspension? However, I am not sure how to describe this one.

Twice during the 6 months that we have owned our 2010 Prius, a loud clattering noise from under the hood occurred upon startup. After shutting it down and restarting, all was normal. It sounded like an engine that was getting ready to throw a connecting rod. The dealer could find nothing wrong and when I contacted Toyota's hot line, they were clueless as well. One service writer suggested the ABS as the source, but I've owned 5 other cars with ABS and never heard anything like it.

I drive a 2008 Nissan Frontier, bought new in Nov. 2007 with 53,000 miles on it. A few months ago, at about 50,000 miles, an annoying clattering noise started coming out of the dash. The noise was coming from the vent area of the passenger side dash and occurs when I start the vehicle or adjust the AC from Max to norm. I went online and found that the noise occurs in many of the full size Nissan SUVs, and is a failing Vent Actuator part. Doing further research, I learned, the part is fairly cheap, but buried in the dash and difficult to get to.
Of course that means that labor is very expensive to replace this part. Nobody seems to want to take the time to replace the part, except the dealer who wants $500 labor to do it. I have found dash diagrams and since it is cooling off lam thinking about taking on the project myself. With the vehicle having such low mileage, and little stress being put on the part, I feel that the part is of low quality and replacement should be covered on some kind of warranty. Nissan probably feels it is not a safety issue, but the noise is very annoying, and certainly lowers the value of my vehicle, that has otherwise been pampered and in like new condition.

Suspension noise I am getting from my 2011 MD.
This noise occurs only over small shock type bumps IE, train tracks that are not smooth, those reflectors in the road, and the metal plates over construction projects. Any bump that forces the suspension over a small vertical or near vertical drop or rise of about one inch.
In my driveway I have a storm grate about an inch lower than the surrounding pavement and it rattles over this every day. Now the fun part.
The noise is ONLY when I hit such a bump with the right side of the car. The left side rolls over the same bumps smoothly and quietly.
This noise is also only present over the small type bumps discussed earlier. My dealer has a rough road that they use to test suspension noises and the car rolls down it silently. The problem also doesn't manifest itself over speed bumps.
The noise is still present while applying the brakes on which makes me doubt its a caliper float issue.
The strut brace and lower control arm/bushings on the right side have been replaced by the dealer under warranty but they can not seem to get to the root of this problem as both these replacements have had no effect.
From inside the car it is very difficult to pinpoint where the noise is coming from but it almost seems like the center of from suspension.

Yesterday night I bought my first Prius--a brand new 2015 C2. All seemed perfectly fine till I was driving home from work this evening. I had the passenger window down and noticed a rhythmic clicking and clattering coming from that side anytime I drove past something to echo it back. This was going at about 25 mph in a residential area. It almost sounded like when you have some gravel stuck in the tire, except no gravel and it sounded more mechanical. It was very noticeable. No sound at all coming from the driver's side open window. I took it back out for a couple more drives to confirm that the sound was continuing.
When I drove it off the lot yesterday it had 40 miles on it--the dealer said someone had likely taken it home to show a family member, then brought it back. I truly don't remember hearing a sound like this when I test drove it, but the conditions were very different (other people in the car, window rolled up). I didn't notice this sound this morning, either.
The thing that is extra concerning to me is that on the way home tonight there was some roadwork where the pavement had been stripped from a section, then a large bump where the regular pavement resumed. I slowed down as much as traffic around me but still hit the bump much harder than I would have liked, especially for my brand new car. It was after that that I first noticed the rattling, a little ways down the road.
The car is making so many new-to-me sounds that I truly have no idea if this is just a normal sound or if I should be concerned. The tires look ok, I don't see anything obviously wrong when I look under the car.

Well, even a supposed Toyota specialist shop couldn't figure it out.
Replaced:
Shocks
Strut Mounts
Inner Tie Rods
Outer Tie Rods
End Links
Engine mount
The ball joints keep passing tests, two different shops swear they're ok.
The road by my house is being repaved, as such, it's really chewed up, and when driving over it, it truly feels like the whole front end of the Prius is going to fall off. It's like the loud, dull, clanging of metal bars.

Every time I am on the road I get this flat noise coming from the front like if the strut was out of air or something like that. It is a very annoying sound and only on certain bumps of the road.

it was warmer the day than it usually was so it dosnt make the noise as bad however there is usually a lot of clatter/knock from the engine when cold. does it at idle and while accelerating. it gets less once the engine warms up but has been doing it for a while. car has 93k miles and synthetic oil is used. there is also a metal rattle sound almost like a heat shield that is loose. idk if that is part of the engine issue or not. but it only happens in winter or when temps fall below 60 degrees. kinda hard to hear on the vid but its there.

Since I got my Prius V, i have this noise form the suspension... when i go over a bump, or a hole... It sounds like the exhaust is hitting on something. It could be the brakes too. It does not sound like something is broken, but more like a tin sound hitting on something...
If windows are closed the ride is smooth, but when I open i keep hearing this sounds, and its driving me crazy... Is that normal for Prius V because of the different tiers?
My Accord does not have any similar sounds driving on the same road every day... actually ride with Accord is way better... Is that normal, should I go back to dealer? Car is 3000 miles only...

So I replaced the front strut and the popping is still there. When I removed the old strut it seemed like that would be the problem as there isn't any play in the ball joints and tie rod end.

What is that little noise coming from the engine bay when you unlock and open the drivers door?

I was driving today with no music on and noticed something strange. I heard something "roasting" in the backseat...and looks like the noise comes from the battery vents. It sounds more like "roasting" noise than fan noise. Do you know if the battery was overheating?

My dad has a 2010 prius IV. He told me the other day when he backed out of the driveway and put it in drive he experienced a clanking noise coming from the engine. He said it sounded like metal rattling around. It lasted about 30 sec. then went away. What this may be?? It hasn't happened since.

I have a 2004 Mazda 3 with 90K miles. Brakes, rotors, and rear calipers were replaced about two months ago. About a month after, I started noticing a clattering sound coming from the left rear wheel whenever I drove over rough road. (It sounds like an aluminum pot lid dropping onto the pot.) The shop that did the original brake work took 4 visits to get everything done. Instead of going back, I went to another mechanic who said the left caliper was loose. He showed me how he could shake it. He said the bolts were tight so it wasn't a safety issue.
I went back to the original shop for repair but they could not reproduce the noise and said the brakes/calipers were fine.
The noise remained. I went to a third shop which checked the caliper and said it was fine, but said that I needed new shocks. The mechanic had the car on the lift and was able to reproduce a similar noise on both rear wheels when he hit them with a rubber mallet.
The first mechanic insists the caliper is bad. The second insists it's the shocks.

My 99 super duty v-10 has 227,000 miles. It was a former UHaul unit but seems in good shape considering the abuse it's probably had! I recently started hearing a clattering sound coming from the rear.
Not just turning but in straight line. Very loud even at 2-3 mph, more pronounced in deceleration. I can best describe it as someone shaking a metal pail with about a half dozen lug nuts in it.
Previous threads point at the limited slip. I called the Uhaul after sales desk and he right away said put some friction modifier in and do figure. Eights in the parking lot. I did and The sound is still there.
One poster said the factory LS is garbage and not worth rebuilding. They mentioned the TruTrac as a good replacement and I guess I'll investigate that further.

My 2010 Prius V just past the 24000km mark. I have a buzzing noise coming from the engine bay during startup. It happens when the interior fan is on. You can hear it clearly after you start the car, during the silence of the "boot up", before the ICE kicks in. I can't be sure if it continues to buzz after that because the sound of the ICE drowns it out. However, If I shut off the fan during the boot up, the buzz disappears. Finally, if I leave the fan off and start the car, there is no buzz.
During a recent oil change, a hybrid technician claims that this is normal. It used to happen infrequently but now it is consistent, so if it was normal, I should have heard it when the car was new.

This is the second night in a row that we hear a noise coming from the back of the car. I know that some noises are normal but this is after the car is stopped/parked in the garage for some 5 hours.
