Prius (2004-09) :: Low Groaning Noise That Comes From Inside The Cabin
Jan 11, 2016
I'm trying to figure out what is wrong with my Prius. A few weeks ago, there was a big rainstorm in California, and I accidentally backed into what I think was a storm drain under very deep water. I heard a big thunk, but there was no visible damage to the car. A few days later, I noticed a low groaning noise that comes from inside the cabin, somewhere around the center console/front passenger side. I usually only hear it when I am moving at low/moderate speeds and turning the wheel to the left, although occasionally if the road is bumpy I hear it with my wheels straight ahead. For a couple weeks, I thought the noise only happened when moving-- however, last Friday, I was sitting in the car, which was parked on a hill with the wheels curbed (steering wheel all the way to the left). I turned the car on, and immediately the car started groaning (even though the car was in park). Then, after about 30 seconds, the gas engine turned off (I think that's what happens when the car gets much quieter after idling for a bit) and the noise stopped. SO, it happened when the car was in park as well.

I'm new here to the F-150's forum although I've owned a few since 2001. I bought this F-150 '05 5.4L Lariat. Really nice truck. But when I purchased it, it had this weird noise inside the cabin. I thought because it had a camper on it that some tranny noise was coming up thru the camper and the rear cab. After taking camper off, the noise was still there. From everything I've read online, it could be rear pinion seal, differential bearing, tranny, front hubs, etc. I have left a video. Pay close attention to the little whine. Kinda hard to hear if your not listening for it.
Note- when i drive it is most definitely coming from the middle to rear of the truck. But I'm not ruling out anything. I have looked underneath the truck and the differential is dry and the driveshaft area near diff is dry. No leaks. I have not checked fluid in diff. Is there an easy way for these trucks? I have read and heard about adding an additive? The noise starts at about 10-15 mph all the way up to 80. I've never taken it past 80 but I'm sure it's still there.

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.

120K (64 by me & 56 by prior owner during first 6 1/2 yrs) I was having a groaning noise when going around corners especially when headed down hill and hitting the brakes at the same time. I also had a rattle or popping going over bumps. I couldn't isolate the noise and nothing felt loose in the front end when I jacked it up. The dealer said the lower control arm bushings and ball joints needed to be replaced for $1545. I asked about front struts and was told that the control arm bushing and ball joints had to be replaced first before the struts could be examined.
I replaced the control arm assemblies (had to lower front cross member while supporting engine w/large jack and removing lower engine dog bone), ball joints, stabilizer bars and stabilizer bushings myself. Ball joints required removing axles and steering knuckle assembly to remove metal CV dust shield on back side of steering knuckle. (will post procedure later). Had lined up and the noise changed (groaning on corners left and rattle became pronounced on all bumps like the front end was about to fall out). By the way no cracks or excessive wear on any of the rubber components as I have always seen on the Subaru and other cars I had.

my 2002 chevy s-10 started making an air/hissing noise inside the cab. It seems to be coming from around the air conditioner controls (center front). It hisses while running, whether moving or not, does not change when the air conditioner or fan is running or not, but does improve when accelerating quickly. What could this be and would it be an easy fix or a professional job (my husband restores old cars, but doesn't do a lot with the newer ones)?

If the windows are closed you can hear it much better. The best way I can hear it is when I am stopped and i step on the gas just enough to get the rpms up. Another way to hear it is when I am at a red light on a hill and I am using the clutch. It's a rubbing sound but not as fast as the engine if that makes sense. Would that be the clutch? It doesn't matter whether the clutch is in or not, you can do it in neutral as well. Vw seems to think its the clutch but i have no slipping or anything. 65K miles no engine mods except intake.

Just curious, but me thinks wind noise is now present inside my cabin at speeds above 60mph. Noticed this around the B-pillar? Could it be that the doors "loosen up" their tight seal as the car pounds mercilessly over bumps? 8500 miles in 4 months!

I have a 2004 Ford F150 4X4 5.4L...and lately, have been smelling gasoline inside the cabin. The usual troubleshooting hasn't given me any leads...

A 2 month old 2013 GTI cabin noise is driving me insane. Sounds like whistling or crickets inside the car and happens around 30 mph and above and its hard to point out the source. It is unaffected by vent positions, open or closed vents, air on or off so it makes me think its a seal somewhere. It is very loud :/
The dealership had it for a weekend to try and find the source but they said they taped every corner of it and the noise didnt go away. They also adjusted the doors and no change. Then they said other GTIs like my navi/convenience 2 door trim had them too but I wonder if its just BS.
Uploaded a video about it, but you will have to turn up your volume and wait for around 0:24 seconds in. My cellphone catches the noise faintly but it its loud if you ride in the car.
Do you have a noise that sounds like crickets or whistling and cant point out the source on a 2 Door too?

I have a 2004 G35 that has not given me many mechanical problems. However, before my last oil change, I noticed noise from my engine which I wasnt used to. After 2 days I checked the dipstick and there was almost no oil on it which greatly worried me. I put in two 10W30 bottles and got a normal oil change the next day. Its been a week now and I still hear this noise when I start my car and its idling (cant hear it while driving cuz of the normal engine/road noise). It almost sounds like a noise I would hear from my dad old 70s diesel benz's, just not as loud.
Its def mechanical but I can't figure out what it is or where exactly its coming from. Its been 10 days now since the noise first started and it doesn't seem to be going away. I just checked engine oil levels now and they are near max. When I open up the hood, I don't hear the noise ( over the normal engine/belt noise), but its very apparent once inside the car with the doors closed and windows up. I am worried my car might end up and die on me all of a sudden while on the freeway or if my transmission is going to go bad.

I am hearing a squeaking noise by my right rear quarter panel inside the cabin. How to safely remove the panel. I tried searching but the instructions were vague.

I have grown extremely irritated over rattling inside the Touareg and decided to listen closely in an attempt to identify the guilty panels or whatever is causing all that noise that makes the cabin of my 2004 Touareg sound like the interior of a 1994 Ford Explorer with about 200,000 miles on it.
I identified the rear seat bench as a noise generator a while ago. I wrapped electrical tape around the latch bolts, but that didn't work too well. It seems that the rear middle arm rest rattles quite a bit in itself. The rest of the rattling seems to comes from the rear seat backs, but this is old news.
I noticed that the door panels (or at least that's what I thought) on the driver's door and right rear passenger door were rattling and creating a lot of noise. However, as much as I tried to hit (lightly) the door panel with the palm of my hand on different areas of the door panel, I couldn't get it to make the same noise.
After listening closer while I drove, it sounded like the doors themselves weren't quite closed. They sounded like they rattled on their latches. Something like taking off with a door ajar, but the noise isn't as pronounced. Then I remembered that every once in a while, during a visit to my friendly local car wash, water was entering my vehicle and accumulating on the rear seatbench. Upon closer inspection, I would notice that the water was getting in easily between the rubber door seal and and the door sill.
Two days ago, I decided to check something, and low and behold, I think I found the problem. Those two problem doors don't shut as tightly as the other two silent doors. I ran my fingers along the door crack near the door handles on all four doors and discovered that the two noisy doors "stuck out" some. Just a few millimeters (maybe 1 or 2 at most). I then tested it with a flat edge and it was even more apparent. I then stood behind the vehicle (far rear left and far rear right) and looked straight down the vehicle's edge and noticed that those two doors were sticking out.
I tried to loosen the door latches on the door sills to move the latches in a little, but I found that a T-40 torx is too small and a T-45 torx is too large. In fact, the T-40 worked on the top bolt on both front door sill latch hooks, but would strip the bottom bolt on the same door sill latch hooks. Those 8 point bolts are not torx (duh). I'll have to wait till Tuesday (Monday is a holiday here) to get this rattling fixed. I really hope that this eliminates most of the noises I am hearing. I notice that the front right door doesn't make any noise, and I also notice that that is the one door in the vehicle that needs to be shut extra hard in order for it the shut the first time. If it's not shut hard, it usually takes two or three tries to get it to shut. My 2003 GTI did this as well, with the very same door.

I have a 2011 Camry SE...and its very quiet inside when doing city driving...but as soon as i hit the highway and go beyond 60mph...i hear constant loud engine noise inside the cabin... (Sounds like tapets of a bike)
I talked to the dealership and they said it is normal as its a 2.5Ltr engine and its Sports tuned for higher pickup! Is this normal or i need to get something check?

I have 06 gs300 AWD and recently it started to make that noise. At first I thought my shock/struts went bad and i had it inspect and they are good, ball joint and control arms also good. However, I do not know if strut mount is bad or not. When I go over small cracks i can hear rattles inside but when i let my windows down I hear less. I do not know if the window or door has to do something with it. It seems like coming from passenger side. Btw sometimes i do feel even dashboard rattles a bit.

I am getting some rattling noise from the inside of the cabin between the front and rear passenger doors. I had the exact same thing happen on my first Phaeton at around 25000 Miles. What causes this??

I am working on a 2006 (production date 05/06) F150 quad cab 4x4 lariat with the 5.4 3V. I replaced all the plugs last week(and only 3 broke off) replaced the air filter and standard tune-up issues. Now when it starts up it will get a faint scent of fuel inside of the passenger compartment.
I have checked all of the fuel rail connections and the fuel injector seals for any leakage, Checked for any vacuum leaks, Checked for exhaust leaks, Double checked all electrical connectors. Everything that I have checked is as it should be with no sign of leakage or malfunction.
I can't find any source of the smell under the hood or under the truck. Thought maybe a fuel injector o-ring but can find no evidence to support removing the fuel rail. (leakage) Kinda at a loss here. Getting ready to go to lunch and start back afterwards.

We own a 2013 RX 350, purchased less than a year ago. We are experiencing this rattling noise coming from inside the side panels, its frequency changes depending on road and weather conditions like if road is rough or if its windy. We have taken the vehicle to Lexus Service three times so far for the same issue, they have acknowledged the issue. Last service took almost a month but still no remedy.
As of last service, Lexus took the entire roof liner down to fix the issue but it came back after one day post service.
Noise is extremely irritating because it occurs next to driver's left ear and is annoying as anything can be. Same goes for right ear for the front passenger.
We have owned Nissan Maxima, BMW and Lexus before and none of the vehicles had this issue.

I have a 1999 Ford Taurus. I have noticed a faint knocking sound for about 6 months. I took it in and the mechanic said ' what noise? '. Then it got louder so I took ot back in and he ssid 'bad water pump' I had another mechanic friend check, and he said the water pump was fine. Plus, I've never had any overheating . a 3rd mechanic said "could be loose torque converter bolts." It sounds like metal clunking on metal under the hood.. rpms, speed, & temperature make no difference. Occasionally get a smell of coolant inside the cabin . I'll attach audio of the noise.

I recently turned on my AC and heard a "flapping" noise from the cabin air circulating fan blade. After a minute or so, noise gradually subsided. Two days later, I turned on the AC and a smell most foul filled the cabin. Being a farm boy, I know the odor of ripe dead animal and I'm guessing a mouse. Is there any reasonable way to gain access to the area where the fan is so I can attempt a clean-up?

I own a 2007 Prius Touring w/120kish miles. We are currently experiencing a huge booming resonance at idle and low RPMs. The noise isn't subtle, almost sounds like we're in a Huey with the doors open. Here's what I believe I know:
- No DTC's are being thrown
- ICE seems as smooth as ever
- No apparent changes in fuel economy
- Plugs were replaced 40k ago and coil ignitors are original--not running rough or missing though
- Visual inspection of exhaust shows no leaks or contact with body
- Motor mounts pass the test I looked up [in drive/reverse, depress brake, watch unusual engine displacement]
- Noise is not vehicle speed related, only engine speed coupled--probably between 1K and 1.8k rpm
I'm sure I'm leaving something out but aside from messing with the coils or plugs I've looked at everything I can think of. I haven;t gone to the dealer yet. Lot's of reading searching have only revealed CV issues.

Hearing a slight clunk noise inside the back of thier gen 2? I've taken apart all the paneling used foam tape to secure things and took apart the spare tire area etc and the clunk persists. It seems to vary intensity every time I close the rear hatch.
