Prius (2010-12) :: Rattle When Cold Only On Certain Rough / Washboard Surfaces
Oct 17, 2012
Just noticed a rattle above my head when temp drops below 60, only on certain rough, washboard surfaces. I am running 44/42 PSI, so I know what I am getting into. I have no intention to fix the rattle other than cranking up the radio. I know when cars age, they eventually develop more rattles. Question is, when left alone, do rattles do any long term harm? As in loosing something else and create a new rattle, or get worse.

I just bought my brand new 2015 Hyundai Sonata 2.4L SE 3 weeks ago and have put 4000kms on it so far and from last week I am getting a rattling noise from just behind my steering wheel while going over washboard surfaces every time. Feels like something plasticy is loose around the upper steering column which rattles every time I go over a washboard surface. My university campus has a lot of rumble strips to slow cars down and that is where I noticed this noise very clearly.
I have taken my car to the local dealer and the mechanic there have acknowledged the problem after comparing the noise with a new car there. He tightened some bolts around the lower steering rack apparently but the problem is still there. He says to bring the car in after the problems gets significantly worse because it is still not severe enough for him to diagnose it and find what is causing it. I do not know much severe I need to the let the problem get before they do something about it. The dealership still has the ticket open for me; I will probably try to visit them next week again.
This thread more or less describes the problem I am having : Steering wheel noise over bump .....

When I go over bumps or rough surfaces I hear a rattle in the rear suspension. It sounds similar to the noise bad ball joints make. I recently had the car aligned and the shop said they couldn't find anything wrong. I'm going to take a look myself but was wondering if this might be a common problem. If maybe there are certain bushing that are known to wear out.

I have an annoying rattle the occurs on rough road surfaces. It comes from the front right wheel area but goes away instantly with light brake pedal pressure. Three trips to the shop have not identified the problem. I just read somewhere that there are "anti-rattle clips" or springs on the brake calipers. Is this right and are these the same as the retaining springs/clips that can be seen from the outside through the slots in the alloys wheels?

I have owned my 2011 CPO rx for a bit over two months now. It has 19 inch rims and Michelin tires. I find the suspension to be much harder than I would have expected on rough surfaces. For example, when I drive over even medium expansion joints the suspension is somewhat jarring. The fact that the suspension doesn't absorb more of the road surprises me. My wife drives a 2011 MDX and that is much better over similar roads. I always thought that Lexus had more of a reputation for a plusher ride. Could it be the shocks already? The car only has 33,000 miles.

I had a eureka moment the other day when braking over a rough surface and I think I've worked out why the Prius (and other hybrids) feels like it skips more than other cars when braking on a rough surface. It only occurs on light braking, i.e. when on regen, it's because the rear brakes are not engaged. A normal car would have all 4 wheels braking so if the fronts let go momentarily the rears hold the car steady.

I have an RX 450H and noticed that there is a squeaking sound coming from the dashboard. I looked at other posts where people were experiencing similar issues and noticed one post where someone had a GS 450H and fixed this issue by adding felt between the dashboard and the windscreen.
I would like to know whether this method works 100% and whether I can apply this method to the RX 450H. The noise becomes worse when it is cold and especially when the car is being driven over rough road surfaces and speed bumps.

I've been recently having the engine rattle/knock noise occasionally when I start the car. After my first oil change, I mentioned this to the dealer and demonstrated this to them while they documented the issue. I left my car at the dealership for investigation.
The following day, my dealer said they called Toyota and created a case about this. Toyota responded saying they heard about this and the possible root cause is the Motor Mounts on the Prius. They will be sending parts (date is still unknown) to fix the issue. :rockon:
I specifically asked if there is any damage to the engine and they said absolutely not and there is nothing wrong internally with the car. This also makes kinda sense because if I press the accelerator to the ground when it starts up, the knock doesn't appear. It also works if I put the car into D and drive away.

Currently working on a friends 2011 Prius with roughly ~340,000 miles (!!!!!) that was used as a taxi, until now, he bought it from the taxi company and converted it his own daily.
I did a regular oil change on his Prius, and decided to change the spark plugs as at the time there was some sort of occasional shaking/rattle at cold startups. The shaking was gone after changing the spark plugs. This was all done back in March. Yesterday, he was driving, and all of a sudden, the knocking came back, a check engine light, and white like cloud smoke appear. Check Engine lights were P0300, P0301, P0303 (misfire cylinder). I told him to bring it over, I took a look, and his invertor engine coolant was all the way down (he told me he filled it up to top just two weeks ago). I originally thought maybe it was the ignition coils (for shaking), but the white smoke didn't make sense. So I purposely filled the coolant above the full line, and took it out to drive for about half a mile, and just as I suspected when I opened the hood, the coolant level decreased, at least by an inch.
I did not see any oil leaks, and the oil levels were just fine. The car just seems to shake/rattle at startup and when accelerating at low speeds (roughly 8 - 15 MPH) and than goes away, and drives normally. It still does blow off that white/cloud smoke when accelerating hard on the engine though. As for the smell of the smoke, I can't really tell, it is definitely not sweet, but it kind of smells foul/bad.
At this point, I am pretty sure this engine is gone, and the gasket/seal is blown.

Well a picture says a thousand words so that plastic cover?/roof tonneau?/whatever is rattling when the top is up. Its a bit annoying when everything else in the cabin is tomb quiet so im going to try to remedy it tomorrow with some adhesive silicone. The same stuff that prevented leaks into my trunk will now be used to stop rattles (I hope).

I have a 2009 Subaru Outback with 60K miles and this problem has been present since I purchased with 30K miles. When turning left or right over uneven surfaces (like washboard dirt road, potholes, or strips of Botts' dots in a parking garage) there is a loud, audible rattle coming from the front end. It sounds like to metal pipes hitting together. The noise does not happen when driving straight.
Subaru and another garage have inspected. Front struts and sway bar links have been replaced with no effect. CV joints, ball joints have all been inspected with no issues found.
I read on a forum that it may have something to do with the power steering fluid, that when turning there is uneven pressure on both sides and it results in the noise. Possible at the steering column universal joint.
I assume since it only happens to some Subarus that replacing the correct parts will resolve the issue.

So I had 1st rough cold start today on 2010 Prius with 72K. Wasn't too cold low 40s. The fix was to shut it down and then turn on again.
Engine sounded like it was working on 3 cylinders. It is probably ignition or perhaps valve train issue.. with ignition being prime suspect. If it happens again I'll pull and check plugs.

I am after a annoying dash noise that I get when driving over any rough surfaces. I have removed all centre console and glove box and everything else around that area and I still have the noise, its like the dash is loose some where else, I have looked around for a complete dash removal instruction thread, but can not find anything??
It looks like I will have to remove the whole dash but really could do with some instructions on how to do this as I don't want to break anything!

I own a 2009 Santa Fe Limited AWD with 56,000 miles on it. I purchased it new in July of 2009. I have started to hear a severe clunk in the front end when driving over rough surfaces/potholes. Not when turning the steering wheel. I have read about issues with front stabilizer link bushing. The Santa Fe is at the dealers and they said it is the front control arm bushings. $1000 to repair!

My new Sonata Limited 2.4 has 17" wheels and Kumho tires. On certain rough concrete, or more often asphalt road surfaces, at highway speeds, this car is so noisy that one can hardly carry on a conversation. It's terribly loud. Dealer has "checked" it, and tire dealer has looked at the tires. No problem has been found. What can be done about this?

Glove box rattle on the 3rd gen RX. Mine makes a slight noise over very rough pavement. It seems to make noise at the latch, so a felt is probably not going to work.

I have had a rattle that lasts 2 seconds on my 2012 Elantra for the since about 2 oil changes ago. The car has 152,000 miles on it and I've changed the oil regularly per the maintenance schedule, although not always with a Hyundai filter.
I'm strongly suspecting that this is the timing chain tensioner, but I could be wrong. Other than this, the car runs fine. I tried having the oil changed by the Hyundai dealer with the OEM oil filter and the problem appears to be a little worse. It first started to appear on cold start up after the car sat for >8 hrs or so. Now, it appears on cold start up >2 hrs. I noticed that the dealer put 5W20 in it.
I'm wondering if lower viscosity oil makes the problem worse during hot weather. It seems when the weather is colder it takes longer for it to appear. I'm wondering what my options are here. I really don't know how much $$ it is to go after the tensioner and how critical it is - the dealer said they do replace them and that doesn't always fix the problem though I'm not sure what he meant. I have read a few other posts about tensioners here, but I'm also wondering if this is an issue with the new engine.

So I recently bought a 2010 Chevy Silverado LTZ with 31,000 miles (5.3l engine). After having the truck a few days, I have noticed a couple of problems ...
1) I have noticed there is a rough idle in the passenger seat while the truck is in drive. Once the truck is started and driven about 5 minutes, once you come to a complete stop in drive (ex. stop light) a rough idle over takes the truck. You can feel this idle a lot more in the passenger seat than in the driver seat. The RPM gauge also fluctuates during the rattle.
2) At night my the headlights flicker randomly, on and off very quickly.
3) In the morning when I start the truck and drive it a bit, I hear a rattle which sounds like it is coming from the front right of the truck. Bumps do not trigger this rattle, which usually only lasts a couple seconds. I usually hear the rattle between 1,000 and 1,200 rpms.
I have taken the truck into the shop 2 times to get these items fixed, and they said they cannot feel a rough idle.

So I just got my new 2015 Elantra SE - and of course, noticing every detail that is different. I feel as if it is 'skidding' when driving on uneven surfaces - and I don't mean off road, just regular I-95 and major roads with humps and bumps in the very old and used roads.

I have a Hyundai Elantra Limited 2012. A few months ago the Short Block was replaced because the engine was noisy. Now it started to do that noise, if I remember it's a little bit similar : Youtube video: [URL] .... Or search youtube for: Hyundai elantra 2012 engine rattle noise
It rattled very loud for 1 or 2 seconds on a cold start the other day too. Noise appears to be coming from the engine. It does it pretty much all the time, at idling, when I accelerate it accelerates too and when I slow down it kinds of do too slowly. Need another new short block or is it something else like the timing chain or a bearing?
