Prius (2004-09) :: Metal Cranking Noise When Driving On Dirt / Rough Road
Apr 11, 2015
I just got a 2007 Prius and using it mostly on a dirt/rough road. My problem is that there is a metal cranking noise coming from under car and trunk. This is nit happened when i drive on a good road.
I already asked the mechanic to check sway bar, shocks, struts, and brake. They said everything is okay except the front left strut boots which is already worn out. But the strut itself is still in good condition.
I'm OK everything except the noise. Already replaced new tires but it doesn't work....

My 2003 Honda Element sometimes generates a vibration that feels just like driving down a washboard dirt road. You know one that the ridges are very close together. This only happens around 40 MPH with a load on the engine. At first I thought it was a wheel, tire or suspension issue. But I can make it stop instantly by pushing or releasing the gas pedal. So this leads me to think it is transmission related. This is a automatic. I would like to see the car sometime but would not feel right about passing on this problem without knowing the cost to fix it. Stumped in Seattle.

I noticed when driving on a rough surface/road (gravel, snowy road with sand) the there is a considerable amount of noise coming inside the cabin on the rear end especially.
When I was doing a quick wash today I just realized the sound is coming from the wheel base. On the rear and front end there is a plastic covering the wheel base. Sound proofing / undercoating wheel base.

My 2012 RX350 now for over a year and like it a lot.........BUT.
There's seems to be a lot "road noise" that's transmitted back into the cabin, like driving over expansion joints on blacktop or rough road surface, is this normal?
I drove a 2000 RX300 for 100,000 miles and don't remember it being this noisy. Interior noise is great and quiet.

We have an 07 F150 XL reg cab. Having problem with the doors rattling going down a dirt or bumpy road. They sound almost as if door weren't shut rite even though they are slammed shut. We took it in to the dealer and they said they adjusted and replaced door stops but we still have the same problem. plus they said they could not duplicate.

I hear a bit of a squeaking noise. Very minimal. Coming from back when I'm on rough roads. Is that normal. Sounds like it might be from coilover or somewhere in the back.

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.

My 2009 Accord is making a metal on metal noise when I drive. It's not all the time, probably about 1/3 of the time or so, and only when I'm accelerating/cruising, not braking. It's very loud, and when I took it to a mechanic they just took it for a ride, didn't hear anything, and told me to come back when it's more consistent. What it could be? I'm nervous even taking it out now.

I have intermittent metal on metal grinding noise. Seems to happen when I am at highway speed. Seems to go away when I put it on 4 wheel drive or slow way down. On one occasion though, the grinding noise did not stop even after putting on 4 wheel drive - had to stop completely before it went away (did not come back after I drove off again). Diagnostics so far....
Unhooked the vacuum lines on passenger side actuator and hooked up vacuum gauge. Vacuum held at 20 psi and drops and raises slightly as the truck is being revved. Takes about 10 seconds for vacuum to drop to zero once truck is stopped. Putting it on 4 wheel drive drops it to zero immediately. Exact same scenario on the passenger side.
This leads me to believe my IWE solenoid is ok. So also my check valves. Next opportunity I get, I will raise one wheel, remove the vacuum line on that wheel and apply vacuum with my pump. Want to see if it will turn my half shaft.

I commute 180 miles a day, 6 days a week. I noticed metal on metal grinding noise(more noticeable) at high speed above 75mph especially on asphalt road. I'm sure noise is there at low speed but not enough to notice. My car has 50,000 miles. Tires? Electric motor?

I recently worked on a 2006 with 140K miles that presented with the following symptoms:
The hybrid battery was at 1 bar; the ICE would not start; the car was in Ready, but there were no codes. As I let it roll off the flatbed wrecker in Neutral, it felt lumpy. If you have ever pushed a car (or run out of gas in one) with a manual transmission that was in a high gear, engine off, it felt just like that.
I popped the hood and could see that the engine crank was turning while the car was being pushed in Neutral. What else turns with the wheels? MG2, or more specifically, the MG2 ring gear. What is the only way that the wheels could turn the ICE crank? The planetary carrier pinions were locked to the ring gear.
Surprisingly, while I was looking at things, it did manage to start the ICE pushing it around must have freed the carrier pinions, so I let it charge the hybrid battery. It was basically the worst metal-to-metal noise that I have ever heard! I pulled the drain plug and saw about a teaspoonful of large metal chips on the magnet. The fluid condition itself was very good, not the black factory fill that I am used to seeing come out.

I have a 2011 Prius with about 32K miles on it. I've been hearing light metal on metal grinding noise for a few days now. So I decided to take it to a stealership and they told me my ceramic pads and brake rotors both need to be replaced for all 4 wheels. I thought Prius brakes don't need to be replaced for 100K miles.

I had the PCV valve replaced around 60K, then at the next service they wanted to do it again (not reading the records that they had already done it). Then at 80K they wanted to do it again, I declined. Today it was in for 85K service and they said "the PCV valve is dirty and needs to be replaced." The advisor told me after the initial replacement at 60K the interval is 20-25K miles.

Strange thing on my 2006. Driving on curvy road, would occasionally get just the "Red Triangle" exclamation point (for a second or so) -- and also the word "Problem." would flash up on the display.
No permanent check engine light or other icons lighting up. Still getting 40MPH, everything seems to be driving right. Have 135K on the odometer.
Question - does that triangle thing store codes that can be read by an OBDII reader each time it flashes -- or does the check engine light need to be on?
Second Question - Any clue what the word "Problem." with no description could refer to? It goes away at the same time the red triangle goes away.

This is a 2001 Prius - car runs great and the AC is fine. However, driving down the road, when the AC is turned on there is a noticeable scraping/ticking noise - sounds like it coming from under the hood.
With the car parked, and the ignition ON, but without the gas engine running, there is no scraping noise.

So, fresh off the new brake actuator pump and new hybrid battery and a nice four hour drive yesterday and today i went over a small bump and started to get a loud clunk/rattle coming from the driver's side front wheel area.
It got worse as I drove home and even rattles going straight on a fairly flat road when i hit only minor imperfections. It sounds like something is loose. I cannot reproduce any noise bouncing the car or rocking it side to side.
Prior to this I would get a squeak/groan from the driver's side when I would go over speed bumps and similar large dips or rises, but that has been curiously quiet for awhile.

I'm pretty sure I know what the problem is since when I hit the brakes it stops. When I took the left side tire off and right side I compared and there is a thin metal sheet that has room to move on the right, but is tight on the left. When the brakes were done before maybe it didn't seat correctly or something. Just wondering what that plate is called so I can order one and change it. Driven that way 2 years, but it bugs me when the window is down and people probably think my car is falling apart. Maybe I'll search for a brake diagram.
Edit: I think they might be called "anti squeal shims". I saw a picture of them, so maybe they didn't put enough high temp grease, but the left side is tight and the rights side you can move a couple milometers side to side so I'm sure that's the jingling noise.

2005 with 106K miles, New Michelin Defender XT tires
I had both front hub bearings go out on me recently and replaced them with a Moog and a Timken unit (2 weeks apart). After replacement, I still notice what sounds like dry bearing or gear noise at 35-38mph, starting at about 25. There could also be tire noise mixed in. I don't drive this car normally, so it's hard for me to figure if this is normal noise for this car. I know the tires and low sound deadening on a Prius makes it much noisier than other cars, but even so, I just want to make sure there is no well known issue with other components. When the car gets up to highway speeds, that noise is masked by regular road and engine noise and the overall noise level is about what you would expect for a car like this. The noise at low speed remains the same whether in straight line or in a turn, or with the engine in neutral.

Starts getting loud above 35mph, local tire shop recommends replacing the struts- says they are causing bumps in the tire because the tire is bouncing along as I drive. I did feel bumps going across the tire when I passed my hand across it.

I have got this noise which sounds like a light skimming of metal on metal. It sounds like a roller (airport baggage) spinning. It can be heard mostly when driving next to a wall or past parked cars. I suspect it being the bearing in either the water pump, idler pulley or even alternator. The car has 330000 kms but it is serviced regularly in which all fluids have been changed over time. I just want to drive through a tunnel and not hear any non harmonic sounds coming from the front.

What the heck could it be? It gets a little louder on left-hand curves of the road, but pretty much constant. Its not the tires, they are new as of a few months ago.
