Prius (2010-12) :: Squeaking Sound Comes Out In Wavy Roads On Both Low And High Speeds
Jun 22, 2012
I bought a 2010 prius 3 weeks ago and a squeaking sound came out after driving it for a week. The sound is like a wooden bed not screwed tight being shaken. My prius has 40000 miles on it and the warranty has expired already. I brought it to a toyota dealership and they could not find where the noise is coming from. I decided to bring it back to the dealership I bought it from and they also could not determine where its coming from. They said they need more time to find it. The squeaks often comes out in wavy roads and bumps and in both low and high speeds.

My '93 Metro 3 cyl (The Phoenix) is becoming a bit 'Long in the Tooth'...
Now, this summer, it has started creaking and popping when I go over wavy roads or take sharp curves at speed.
If I accelerate/decelerate the frame pops over on the passenger side and I hear pops in the trunk area.
I wonder how much longer it will be safe to drive.

About a month ago, I purchased my 2013 Prius Four. I've put on about 2,500 miles so far and recently started noticing when I start the car up, it is giving off a high pitched squeaking noise. This happens both when the car is using the electric battery and when I can feel the gas engine kick in. After about a minute or two, the noise goes away and doesn't come back.

I drive a 2002 4-dr 1.6 L Accent and there is a strange, high-pitched squeaking that comes about from somewhere under the car at very slow speeds (30 mph or below). If I hit the brakes, the noise continues sometimes as the car slows. (The noise isn't the brakes, though, I know that), but if I hit the gas pedal slowly, the noise stops. Whatever is vibrating underneath doesn't seem to be causing a problem at high speeds. Or I just can't hear it.
Secondly, I am going to try to do some tune-ups for the summer for lack of better things to do, mostly, I can pretty much do anything (intake/exhaust, engine, electrical) as long as I can find detailed instructions.

I've noticed, maybe a handful of times in the 5k miles I've owned the car, that the engine will rattle excessively for maybe 30 seconds or so on a drive. This only happens during high load/low speeds and I think after the engine has been off for at least about 10-15 minutes. It doesn't happen on start up, only after the car is warm, but hasn't been using the engine for a bit. I'm thinking this is fuel enrichment (really rough running) because the cat has cooled.

Correct me if I'm wrong - Pulse & Glide is not really possible at speeds higher than, say 120-130km/h (74-80mph). I have noticed on my last trip that if you want to keep 130km/h average and you pulse up to 140km/h and glide down to 120km/h, when "gliding" the engine never shuts down, and the glide period is very short.
When pulsing back to 140km/h it takes a "long" time and the instant fuel consumption is "high" (e.g. 6-7L/100km) while when "gliding" you are actually at 2-3L/100km, which means on average you are at about 5L/100km, which is what I would get in any case if keeping speed constant with the CC at 130km/h.

I have been noticing a squeaking sound lately, what it might be. I notice it most when parked in the garage and I am getting out of the car (obviously with the car in Park). It seems to happen when the car rolls slightly, forward and back against. I tried to take a video to capture the sound. The car was parked and shut off, and I was pushing the car forward and back to recreate the sound. The sound SEEMS to come from the front (maybe the right front), but it is not easy to tell.

The temperature has dropped down into the 30s here and in my 2011 Gen 3 Prius, when I am driving at highway speeds (55mph-75mph), and go over any sort of light bump or rough road (gently rough, nothing significant just normal "imperfect" highway bumps), there is a rattling sound coming from the front of the dashboard where it meets the windshield that can only be described as the same sound that your hand makes when it's rubbing a balloon! Not your normal plastic random rattle, but like "rubbing a balloon with your hand quickly" sound.
I don't mind that other plastic random rattles from time to time (I am not OCD about the imperfections of how much plastic is in the car), but this is obnoxious and I feel like I'm literally driving a clown car. Is there some sort of lubricant or adhesive that is between where the dashboard and windshield meet that has possibly dried out, that the dealership could quickly fix or apply? I'll still under full warranty at 22k miles.

I can hear rattling coming from the driver's door at low speeds on uneven roads. At higher speeds there are no noises, it only happens at speeds of up to 50 km/hour. I removed the door panel and there are no loose parts.

My 2004 V8 Toureg has around 7K miles on it. The brakes are squeaking at a very high pitch. The same squeaky sound a bus makes when it stops. My dealership told me it is due to me not hitting my brakes hard enough. I have hit my brakes hard many times as of late and the squeaking continues loudly as folks will turn their heads. The dealership told me it is due to brake dust accumulation which if I wash the car they still squeak. Dealership also told me the VW regional field rep has told them that to rough up the brake pads which is a temporary fix. Dealership also stated if the brakes were replaced the brakes would start squeaking in a matter of a few months because this is how German cars behave. Not sure where to take this matter.
My other problems as of late are a bad power steering pump(replaced), bad suspension controller arms(new parts are ordered-kept hearing a popping sound when turning the tires and braking and grinding noise from the suspension), a bad keyless access module(replaced), steering column not centered(re-centered), wind noise from the rack ontop (basically to fix and probably only temporarily, unlocked them and then moved them forward a bit and then back to their original location- may have been loose as no more wind reverberation inside the car now), and rubbing from my driver side wiper. The brakes are the real thorn in my side at the moment due to other drivers hearing the noise while driving as they turn their heads. Very embarrassing especially coming from a new car!!

Noticed the barely audible (with good ears) high-pitched sound that emanates from the car when you let off the throttle enough to prevent any charge or discharge bar from showing? It goes away if you completely release the throttle or if you press the throttle a tad bit more.

I have purchased a 2010 III Prius with 73K miles last week after my 2006, everything is fine for me but I have a scary problem , the engine sound is very high while driving even after enough warming up, specially when the ECO meter reaches the PWR area or when accelerating hardly, I tried changing the engine oil with synthetic 0W-20 and the filter and the sound still the same.
Check the video attached and also note that
- Its winter here and temp is 50F.
- The car was imported from the US,
- The speed in the video in KM/h.
- I am using clean OCTANE 95 fuel.
- The video was after driving 20 Miles.
- I have latest version of Techstream with original Mongoose MFC...

I was driving today and had just gotten off the highway. I was going at no more than 10MPH when I heard some high pitched sound. At first I couldn't figure out what it was and thought maybe it was some outside noise. It quickly got louder over the span of the next few seconds and then I realized it was the engine. I had the pedal barely down so was definitely in electric mode.
I quickly glanced at my Scan Gauge and actually saw the RPMs go from 1200's up to 3400 in no more than 10 seconds. I have never had the car rev this high, probably just 2400s when I'm on the highway going 70's. By this time I was getting very perplexed and worried, and had my foot completely off the gas pedal. I immediately pulled to the side of the road and parked (hit the P button). The car seemed to go into park mode fine and then over the next few seconds the RPMs went back down to 992, and I made it back to the house no problem.

My car has the wavy acceleration feel and sometimes hesitates a bit. It is way worse when the a/c is on. I wonder if this is a octane or sparkplug issue. On my old cruze 1.4t the gap was wrong from the factory. It came with all four gapped under .022 but the manual called for .028. Everyone gapped to .035 with great results. Not checked the sparkplugs yet?

I have a 2002 accord 4-cyl with a 5-speed with 89,xxx miles. Just a few months ago, I noticed a clunking sound coming from the front suspension when I go over certain bumps. "Certain" bumps are usually wavy pavement or dips (not wide dips, but short/concise ones), and sometimes certain speed bumps. Sometimes the sound happens regardless of the types of bumps though, but the aforementioned ones usually bring the noise quite consistently. The sound hasn't really gotten worse, but it hasn't been getting better either.
A while back when I had my timing belt done, the mechanic stated that one (or more) of my engine mounts were worn. Is it possible one or more of my engine mounts is the source of this issue (from the engine "rattling" around in the compartment. I'm not sure if that's even possible, just a hypothesis) or is it purely suspension. PS. The sound isn't quite a sharp metal on metal sound. Its more of a "thump" or "clunk" coming from the front end (left or right) as if its bottoming out or a bushing or spacer has worn off. Its just loud enough to drive me crazy, and sometimes I can feel it through the floor.

My Prius IV with about 10K miles started to emit a high-pitched electrical humming sound under the hood when it was in Ready mode. It did not have this sound before. I opened the hood and found the sound was coming from somewhere around/under the engine area. I want to know if this is normal on Gen 3 Prius? I have seen post on the same noise in Gen 2 Prius but the posts (thread) stopped without a resolution.

I have had my prius IV with solar roof for a few weeks and when the roof is open and i go over any bumps or rough roads it rattles and the amount of noise varies depending on the position of the roof.

How I can charge my hybrid battery while driving on city streets with an average speed of 35-45MPH. Once I get off the highway, the hybrid battery is almost full, only missing two "bricks" or "Bars." I will then accelerate very slowly only using the electric motor to drive the vehicle for the next couple of miles.
Once the battery has depleted to where it only has two bars, I will then accelerate a little faster to run the engine so it can charge the battery. But, I bring up the energy monitor and then watch the arrows.. making sure that arrows are coming out of then engine to drive the vehicle AND making sure that the electric motor is not supporting the engine.

I've had this intermittent plastic rattle coming from the back end on bumpy roads at low speed. It's not the license plate and bracket (already fixed that one). Yesterday I happened to tap on the outside of my left tail light and heard it rattle with the same noise I'm hearing on the inside of the car. There is no rattle when I tap on the right tail light.
