Prius (Gen 3) :: Rattle Noise Under The Car When Driven Over Sharp Bumps
May 14, 2011
Took my 2010 with 10,250 miles to the Dealer yesterday because there is an uncomfortable "tinny" rattle heard under the car when driven over sharp bumps and dips (rough road). Almost like a loose brake shield. At oil change I made mention of this and a missing fastener and nut clip was thought responsible. This time I had a test drive with the mechanic and we verified it was on both sides having done several passes on the same road hazard. After a period of trouble shooting in the shop, a decision was made on the front struts, but none in stock. Brought it back this morning for the replacements and was found not to be the problem.
This is one of those noises you can duplicate on the road, but not easily in the shop. Have had no accidents or run overs, and the car is in perfect condition otherwise. It is not the oil door.

When I'm driving over sharp bumps I hear what sounds like a small chain jingling around. I took off the hubcaps and jacked up the car to see if anything loose. I grabbed the exhaust pipe and shook it, but it didn't make any noise. I couldn't see anything that would cause it. The front right strut's rubber cover is off so could the strut make that noise?
I just read a few posts with similar problems, but one was a compression sound and another was a knock, and another was a metallic hick up. Mine is literally like a loose high pitch chain noise and change rattling in your pocket. No uniformity to the sound. But it also only happens over quick small bumps not large ones like speed bumps.

My new Prius C is only 6 weeks old, but started hearing some annoying rattles from the dash area when driven on rough roads (tarmac or roadworks).

What is causing this noise. When the rear of my truck goes over bumps it makes a rattle/clunking noise but I can't find where it is coming from. Here is a video of the noise. [URL] .....

I have a 2012 Prius v 5. There's a metallic rattle sound coming from the drivers side under the car. (I think)
Happens only when going over sharp bumps and even road reflectors. Had this happen on my 2001 Highlander. Turned out to be incorrectly installed brake caliper. Needed new spring clips. Don't think this is the issue in the v. Have about 10k miles.
Can only hear the sound with drivers window down and while driving along a curb, k-rail or wall. What's up?

I am experiencing issues with front shocks RS2 Coilovers. I have this knock occurring from both front shocks. If they're set the softest, they're the worst...knocking noises over all small sharp bumps or sharp dips in the road. If I set them to full stiff and you drive it immediately after the ride is stiffer, but smoother, almost no noise at all, only when driving over roads that throw weight from side to side quickly will create the knock, but very light. However after a while of driving it just starts to make noise again as if they're unwinding on there own. When I check their position, they're where I left them. It feels as if the shock pressure bleeds until I perform the same routine and it feels tight again for a short period.
Its starting to annoy me now, car has 6000km on it and 600 km on the coilovers.

My wife had been complaining about a rattle noise coming from the front of her 10 RX350 when she goes over bumps at about 35mph or so. Could not pinpoint the problem?

I would describe the noise as a low rattle/knocking when i hit bumps(or the second after). i thought it might be my spare tire knocking around in its trunk well under the carpet. I actually removed it and drove around to check, but it was not the issue. I had a mechanic look at wheels/suspension because of this noise, he told me the rear passenger side sway bar link needed to be replaced. I personally ended up doing the work and replaced the right and left rear sway bar links however the noise persists.
while the rear was jacked up i tried wobbling the wheels with my hands to check for play but found nothing in any direction. The mechanic seemed to think everything else looked ok.
I only notice it at low speeds like driving around a neighborhood. The big bumps it either isnt happening or the noise is drowned out by the general sound of hitting larger bumps. But over mildly bump sections such as a bad asphalt patch chop it can be very noticeable.
Its not very consistent, its hard to predict when ill hear it and its almost like its during when my suspension settles after hitting the bump that its heard.

Went to pick up my Touareg tonight. Took it for a quick test drive and there was a noise and rattle coming from the steering column when you hit bumps. It sounded like metal on metal. The tech guy drove it with me and agreed something is wrong. They put it up on the rack but I left because I had been there for one hour and that was already past my mental limit for being in a car dealership. I didn't sign the paperwork. Told them to call me when they figure it out and I'll come back and buy it if the problem is not significant. Everything was going great until then.

2003 passat gl; 1.8t w/all new front control arms, replaced to cure suspension noise, now metallic clatter persists, but any (even) light application of brake pedal and noise stops.. it is most apparent over sharp bumps...

I have the 2012 Touareg with adaptive head and LED accent lights. I have observed that when the road has sharp bumps and you are going slow enough to observe your light pattern on the ground, the lights, the LEDs I believe, appear to be "Jiggling". I realize there must be a more technical term for it but I would think from the oncoming traffic the appearance would be reminiscent of the old motorcycle light heads that were never very tight and would appear to bounce or "Jiggle" up and down as they approached. The dealership says they all do it and it is because the LEDS are mounted in plastic and the plastic is vibrating.

I have a rattling problem with my 2011 Prius and Here are the quick facts:
The rattling typically happens while going over bumps or driving on patchy roads. It happens when running over the "buttons" on the road.
The noise is not related to RPM, or transition from battery to engine usage.
If I had to describe the noise, I would call it a "plasticy" buzzing/ticking.
It definitely sources from the driver side dashboard. Passengers cannot hear it well.
This is a video of the rattling.
I have tried pressing down on various panels, none seem to eliminate or dampen the sound completely.
However! Smacking the light-gray panel below the "triangle window" use to temporarily reduce the noise.
I've tried removing the same panel below the driver side "triangle window" because I thought the noise was coming from there but it persisted.
I read on another rattle thread that the column supporting the roof (and bordering the triangle window) is the real culprit, but punching it only reduces the rattle sometimes.
I've brought it into my local Toyota and they did a search for anything that could be rattling. They didn't work, and after they finished the center console was rattling too (which I've fixed).
Also, cold weather seems to worsen the symptoms. I should also state that sometimes I have little to no rattling, but on other trips there is no end to the rattling.

2006 Azera Limited; 221k miles
I'm a new owner of an old Azera. It's become apparent I'll soon be busting my knuckles ferreting out suspension noises. I gather from perusing various forums that suspension noise is a common complaint with the Azera.
In my particular case, the car makes two distinct noises which seem to come from front right corner. I here "clicking" when driven over minor road imperfections, and "scrunching" when driven over speed bumps. It's likely two (or more) disparate parts have failed.
I noticed significant cracks in both sides of the bushing located where the shock absorber mounting fork (54682-3K000) bolts to the lower control arm (54501-3L000). I'll replace this bushing then determine if doing so remedies the clicking noise at this corner. If replacing this bushing fixes the "clicking" noise, I'll replace its counterpart at the other corner, then move on to identify the scrunching sound.
My problem is, I cannot find a part number for this bushing! ...nor can I find a procedure to replace it. I presume it's just a matter of digging out the old bushing and press-fitting (with soap) the new bushing in its place. Surprisingly, the service manual (first edition) does provide any guidance.
I need the part number for this bushing and tips/tricks for installing it into the lower control arm.

I bought a 09 Sonata GLS in July, really nice other than dash noise, what has been described as crackle. Briefly, my sonata is makes crackling noise going over small bumps, more pronounced in colder temp. I have taken it in to the dealer 4 times, problem still persist. According to the dealer, Hyundai regional office knows of my problem, and there is no fix for it at this time. I just bought the vehicle and I am suppose to live with it?????

Problem #1: So I've noticed a clunking when I go over sharp bumps or uneven road conditions (think roots under the pavement) at low speeds, such as in a parking lot. The noise is only under the front left tire well area, and the car drives smooth and great otherwise. Is it a bad joint? The closest dealership is over an hour away, so I want to make sure I'm driving there with a real reason. The MDX has about 130K, transmission is great, and new timing belt, so I'm scared it's some sort of axle/joint problem...
Problem #2: The check emissions light came on about two days ago. I have filled up since, but it hasn't gone away. There is not a smell from the exhaust, and there is no rattling. Gas mileage hasn't changed one bit either! What could it be?? The car has been restarted quite a few times, but the light comes on each time.

I've had a clinking sound at the front of my car when driving over sharp bumps like seams or cracks ever since about 6k miles. I only notice it with the windows down. I used to think that it was the coils on my Nuespeed sport springs hitting each other, but after I got coilovers and the noise didn't change I was sure that it wasn't the springs. When talking to my mechanic on the phone he suggested that I see if the problem goes away if I apply the brakes when driving over something that causes the noise, and sure enough the noise isn't there when braking.

I know lots of you say these stock Rancho's suck, but I'm wondering if it's just the ride that improves? I have some clunking under the truck when I go over "sharp" bumps that normally I would say is something loose or maybe a bad ball joint...except I have it in the rear as well. Is that a symptom of these stock ranchos? I don't mind the stiff ride, it's the noise that's bothering me.

The roads here in Maine this winter were especially awful with potholes and bumps. My '03 Ford Focus Wagon has recently developed a noise that I can't diagnose. The noise can be best described as a "rattle" from the front end when going over very small bumps/cracks in the road. It almost sounds like loose shocks. They are the original shocks and have 130k miles on them.
Big bumps are not a problem. Car does not bottom out, sway upon braking, or bounce when I put my weight on it and release. Several years ago I had a "creaking" from the front end and my mechanic replaced some bushings which fixed the problem. I originally thought this was the same, but it doesn't sound like that - worried it could be the struts but I want to diagnose it a little better before I bring it to a mechanic and just say that I have a front end noise...

My 08 Prius with 35K made strange creaking noise when driven over bump or dip when it 's cold. The dealer have had the car for 4 days and they said the noise came from bad control arm.

09 stx 2wd 4.6L- I have a 2.5'' leveling kit and 33'' bfg a/t tires. The problem is when I make sharp turns, or turn and go over small bumps. Whats happening is something seems to catching or rubbing it kind of jerks towards the opposite of where I am turning and causes the traction control to slow my truck (sucks on tight off-ramps/ u-turns). this happens at pretty much any speed although it gets worse as speed increases. At first I thought it was the steering stoppers but don't have any wear on them, tires do not rub anywhere. My dealer and a local off road shop cant figure it out...

2004 PSD 4x4 72k. I thought I would be proactive so I bought the front ball joints and have plans to install them but recently I starting hearing (and feeling) a clicking sound in the front LEFT when I make sharp turns to the left and hit small bumps now and again. I jacked up the front end and am able to get 1/4" of movement front to back (top to bottom so not steering) in the wheel.
I narrowed it down to the hub. I took it apart and it is most likely a sealed unit so no adjustment is possible....that I can see.I pulled out the locking hub and got as far as I can to know there is not an adjustment. Need to confirm that it indeed is a sealed bearing and if so what are the part number(s) I may need to repair it.
