Prius (2004-09) :: 2007 - Loud Noise When Driving
Apr 25, 2016
My 2007 Prius II is starting to sound like a little roadster - when I was driving on the freeway behind a large car I thought it was them, or just hoped we braked and hit the accelerator at the same time thinking it couldn't be my car.
Only after that car left did I realize it really was my usually-ninja car making the loud purrs. It cruises quietly and the sound goes away, it's hitting the gas that makes it loud. The mileage is the same, it feels the same, it's just loud now.

Started the car the other day and a loud whining noise followed by the car "jumping" when I stepped on the gas. It would go/stop for a second, then shut down. Mechanic who is not a Prius expert said it was the tranny. He could put in a used one (77k miles). Car has 250k miles on it. Is it worth it? Or should I just part it out. I'm worried about things like the battery going next.

Today when I am driving the 2007 Prius, suddenly heard some noise. I managed to come home and checked. There is a black plastic piece hanging and touch the ground, the noise was from this black plastic piece touching the ground. Attached is the picture.Is this a big problem? Can I continue to drive the car to repair shop to get this fixed?

For the past few months I've been hearing a loud fan-like buzzing noise coming from the passenger side of the front of the car. I don't know that much about cars, but it almost sounds like the engine is racing or something is spinning too fast. It has gotten increasingly worse, and seems especially loud at high speeds on the highway.
It is not the heating/cooling fan - the noise is present when the heating/cooling system is turned off.

I had never been in a Prius until I bought my own 12 months ago. A relatively loud whirring noise accompanied me everywhere I went... "Oh, that's just the electric motor doing its thing!" I would tell myself and my unknowing passengers...
It was my TOTALLY shot tires. Oh sure, they had tons of tread life on them upon purchase, but they lasted a scant 22K miles, got horribly scalloped, developed stress cracks between the treads, and aren't even LRR tires! Indeed, beware of the Bridgestone Potenza Grid019.
The three miles it took to drive home on the TrueContacts were an automotive epiphany. I had no freaking idea how quiet this car really was! Even at highway speed! I feel like a fool.
Well, now I've got an LRR tire, a 6 year/90K warranty, and did it for about 400 total. Shipped to my door for about 350, local place mounted and balanced them for 50.

My 07 prius makes REALLY LOUD TIRE NOISES. It sounds like I have mud-terrain tires on my car. I know I need a alignment because the tires are cupping. Would this cure the irregular tire noise?
The tires are not the stock Goodyear Integrity(?) but aftermarket. I can't recall off the top of my head but I know when I first got them they never made close to this much noise.

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.

I recently bought a 2007 Prius that is making a rather loud knocking noise that has me a bit perplexed. I know the noise is not normal as my 2005 does not do this.
The noise only happens when the ICE is running and the car is in drive
If the car is in park and you rev up the ICE the noise is not present. With that said I do not think the noise is isolated to something in the ICE as I think it would be present when revving the engine in park.
However is you put the car in drive and step on the brake (to keep the car stationary) while lightly revving the ICE the noise is present. The noise is present every time the car is in drive and you accelerating, even with the lightest of throttle.
It does not need to be under excessive load and with that said I am certain it is not spark knock/per-detonation of the fuel nor does it have the "pinging" sound like a spark knock.
If while driving down the road and the ICE shutdown down while driving at lower speeds the noise disappears. When the ICE starts back up the noise reappears.

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.

Our 07 RX350 has 47,000 miles and I just starting to hear (I think from the front) a faint rattling noise while driving. It's hard to describe but it sort of sounds like what you might expect if an empty plastic bottle was slowly bumping around in a plastic box. It is not a metal on metal type of noise. The shocks/struts appears to pass the old bounce test and the car does not seem to display any of the handling issues you get when you have worn shocks/struts.
I also checked the upper engine compartment to see if any plastic shrouds or covers were loose - they weren't.

I am a relatively new owner of a 2007 Prius and am curious about a sound I hear quite often while driving.
The sound is similar to a cd changer changing disks my package doesn't have the disk changer). It seems to happen when braking but I haven't pinned it down to one catalyst.
It seems to be a normal sound and I am not worried about it since riding in my roommates '07 Prius and heard the same sound.

New to the prius world! I recently purchased a 06 prius with 185k. Gas engine needed to be replaced so I recently replaced it. Had code of engine failed to start. Now got replacement engine in and has p0300 and p0303 and p0304. Weird thing is new plugs. Swapped coils and injectors with same results. To me it sounds like a racket in the transmission. The noise is not consistent at all. Very loud and odd. Also inside the car when I put it in drive or neutral a warning light comes up and says shift to park batteries wont charge while in neutral.

I've a UK 2004 gen ii with 69000 miles on the clock. When coming to a stop and also when at a stand still if I press down the brake pedal I get a rather loud creaking sort of noise. I guess that's friction brake related as no noise with using brakes when driving. Also a high pitch squeal when driving and turning steering wheel slightly to the left that stops when you press the brake pedal.

I have a 05 Prius. Developed a low hum noise some time ago. It now is so loud can't hear the radio. Sounds like a heavy agressive truck tire rolling down the road. When turning the steering wheel from right to left quickly, noise level changes. Does this sound like a bad wheel bearing and if so what am I looking at for repair costs?

It sounds like it is coming from the Hybrid Drive. It is really loud. I can hear it as I drive down the road. The best I can figure out from reading forums is it might be some time of coolant pump the drive uses. It starts as soon as I open the door before I start it and it will keep doing it after the car is turned off.
I've posted a video with audio on youtube....

My '07 started making three very quite beeps while driving, happens about every 15 minutes. It sounds like it might be coming from under the passenger seat. Mileage on vehicle 168000.

I'm a filmmaker and I want to be able to turn on the back up camera on the dash while driving forward, aim another video camera at it and record. (while I'm sitting in the passenger seat of course). Better yet - is there a way to tap into the backup cam so I can record directly from that while driving forward? Is there a 'finger dance' I can do to allow this and override the fact that it automatically shuts off while in Drive? I have a 2007 (2nd gen Prius)...

Yesterday when i was driving on highway on my dash board the lights came on: the check engine light, master light, brakes lights. After driving couple of miles my car completely shut down. I took the exit and after that the car didn't start at all. Even i couldn't start the ignition to connect my OBD scaner to read the codes. Now I even can't do something to read the codes or to turn the engine on somehow, what to do.

I know that you're supposed to hear a soft whining noise when starting up and shutting down the car, especially in cold weather. For at least a year now, the noise coming from my front left has gotten much louder and more obnoxious, especially in cold weather.
From what I've seen on this forum so far, I think it is the coolant heat transfer pump. Does that sound right? Or could it be a different pump or piece of some sort? Seems like there has been confusion on this issue, from other threads I've read.
The noise has gotten louder and longer, it lasts about 10-15 seconds now. Especially in the winter, it sounds really bad, I'm afraid the pump is going to fail this winter.
