Prius (2010-12) :: 2011 - Hum Coming From Rear While Car Is Off
Jan 14, 2016
Walked into my garage where my 2011 Prius (have owned for 11 months, now at ~78K miles) had been sitting for about 4-5 hours after being used for a 4 mile trip. I heard a quite battery hum from the rear for about 1-2 minutes. I've heard this before... (it is not unlike the hum you hear in the front when opening the driver's door after the car has been sitting a bit.... and I've noticed that the duration of this front hum seems to be correlated with the time since last drive?). No clue what is was...

I am wondering how much fan noise is normal from the passenger rear vent while driving.
My fan is on almost constantly and it sounds like wind coming in through the rear window but it is actually the fan from the vent. I have had passengers in the front seat ask what the noise is coming from the rear. I have taken it into the dealer 3 times and they say that is normal for Prius' to have that noise all the time.
My Prius is 2011, bought on Feb 2, 11.
I have 5000 miles and the noise has been present from the onset of owning the vehicle. I am really frustrated because it sounds excessive to me. Is your fan on most of the time and significantly audible?

I've been noticing "Hissing Noise" coming from the rear passenger side (rear right hand side) of my 2011 Prius for a few days now. It sounds like the hissing noise is coming from the vent that's located on that side. Not sure what that does, but the hissing noise is usually present when I'm driving at 10MPH or up and it's gone when I'm less than 10MPH or at a complete stop. I have about 32K miles on the car.

I have a 2011 Prius, only owned it a couple of months. Today while it was idling I noticed a sucking sound coming from the gas tank. Not constant, sort of a second of suction then a second stopped, and repeat. Thought maybe the gas cap wasn't on right, opened it and closed it again, then finished driving where I was going to monitor it. The sound continued until I turned the car off. Went to try it later in the day and there was no sound, but I don't exactly trust that it's a non-problem yet.

I sat in the back of my recently purchased 2011 Prius Three, not III, for the first time yesterday. I learned from this forum that the vent in the rear seat is to keep the hybrid battery cooled. However, while sitting the back during a ride, I noticed it was blowing air out instead of sucking air. I would think the vent should be sucking air from the cabin to keep it cool, but that does not seem to be the case here. After a 30 minute drive, I even felt the air coming out of it was warm and the A/C began to feel that it was not enough for my area in the back of the car.

My '11 Prius has developed a problem where the rear passenger door will not open from the inside. It will open from the outside. All other doors function as they should.

I have a leak underneath the rear right passenger door. I see some type of pan underneath there but don't know what it is. How to identify what this could be? This is 2011 Hatchback.

My 2010 Prius was hit while parked. The left side was wiped out and the whole car was pushed sideways about 2-3 inches, with the parking brake on. Toyota checked out the car and said everything looked fine. But there is this odd sounding humm coming from the rear of the car. Toyota says that is normal. Is this true?

It is gone at 120K. Thought it could be the tire, so rotated but noise still comes from driver side rear. Car is a daily driver but we do not live in snow belt, so cannot blame it on salt.

We took a trip from L.A. to Sedona AZ two weeks ago during the top of the heat wave. 120 degrees in Needles and 108 in Sedona for three days we were there. The car sat in the sun at the motel all three days except for one short hiking trip. Everything was fine, car ran great, and I didn't baby it, pretty much 75mph all the way there average. On the day we were leaving I went out to get prepared to leave and there was a distinct HUM coming from the rear, most probably the battery area. After a drive to the gas station and on our way out it resided, but I was concerned. Never heard this sound before.
Second thing is (twice I've noticed this), very hot days, I'm getting a lull in acceleration from stop. Whether in Normal or Power mode it's the same. (I regularly drive in Power mode). When hitting the pedal it *pauses* before it accelerates away, like when you start running out of gas in a gas vehicle.

I seem to be getting a creaking noise (the same sound you get when you lean on the armrest) coming from the passenger side rear. It sounds like it is coming from the hatch, but I can't quite narrow it down. The creaking noise appears when I drive slowly over bumps.

I've owned a 2012 Prius Two for less than a month now, and today while driving home I noticed what sounds like road/wind noise coming from the rear passenger side area. Googling about this revealed information about the battery fan. However, I'm unsure if what I'm hearing is the battery fan or road/wind noise that I just haven't heard before.
Here's information regarding the conditions I was driving in:
- 84 degrees outside temperature
- car had been sitting in an open-air parking lot for about 2 hours
- no tint, no windows cracked for hot air release
- upon returning to the car I turned on the AC to 68, set at mid range speed
- was driving on the interstate doing some stop-and-go, but mostly 50-plus MPH
- windows rolled up completely, no doors ajar
- it sounded like air rushing by
- could not hear anything coming from the left rear side, but my left ear is partially blocked by the headrest, so...
- sound would decrease in volume if car slowed down
- sound would increase in volume as car got faster, but would eventually level out it seemed
- sound would completely go away at speeds below 20ish mph
- sound would not change based on level of AC, whether on, low, high or off
- checked battery vent for obstructions/debris, saw nothing, and was cool to the touch
- car has about 28k miles on it, replaced rear tires yesterday but all bolts, caps, etc. are securely in place

The car is under 25k miles. I have owned for less then 2 years. Recently, I notice a noise coming from the rear every time backing out the drive way. The sounds louder in the winter**. I have gone to 3 different dealers and non of them offered a remedy. Some say they cant reduplicate the issue so I scheduled a test drive with a tech. Was able to duplicate the issue, however the tech says its normal ( pad shift over time) and told me a lot of the newer carmy has the issue. I'm exhausted from going dealer to dealer and no remedy issue. They all said the same thing "its normal & there's nothing they can do".

I have a 2011 Subaru Impreza 2.5i hatchback with a automatic transmission. When I go between 55 and 65 I hear a buzz saw noise coming from the rear of the car. The noise only happens at those speeds,on hills, and flat ground, and in curves, and on straight always, but I never hear it at any other time. What it might be?

A few days ago I noticed that my car started making an odd, very noticeable squeaking noise. The noise is coming from my rear left-hand wheel. It's audible from outside the car, and from inside with the windows down.
The wheel makes a squeak each time it turns, so the frequency increases with higher speed. It's audible from ~15km/h, below which the squeak is barely audible, up to ~70km/h, above which I can't hear it any more, maybe because of wind. It makes a slightly different kind of squeak from the same spot when I'm backing up. There is no other noise of any kind (nothing unusual is heard with the engine on, and the car stationary). There are no other problems at all with the vehicle. It's been about 4000km since my last oil change, I have that coming up soon, but I doubt that is the cause of this, since it's coming from the wheel.
What caused it - my theory is perhaps a pothole or running over a speed bump too fast. Any way, this doesn't seem like that big of a problem, so maybe I could fix it myself. What this could be, or how I should approach this?

Many months ago I had a rattle in my 13 Azera. Of course when I took it back to the dealer they heard it but when I left it was gone. I had a scheduled service to have it looked at but the rattle never came back.
The last two weeks it is back louder than before. I thought it might be coming from the passenger seat belt housing on the side of the door but now it sounds like it might be coming from the passage side rear door or maybe the sun roof. Hard to tell yet my girlfriend was in the car last night said it wasn't coming from the passenger side seat belt housing sounded more like the rear of the car.
So going to make an appointment to get it looked at next week. I hate rattles! I looked all over the car yesterday after had her cleaned up. My trunk is empty, so not sure what it could be.

Currently have 85k miles. About 20k miles ago I noticed when I have the driver window down I would hear a rattle coming from under the car when accelerating. Doesn't happen every time but does quite often. Usually goes away almost immediately. I'm not having any other issues and with my warranty out I'm not anxious for a drip to the dealer.

Have a cracking noise coming from the rear windshield/deck when going over bumps when the car is cold? I've had this consistently since I got the car. It also has been consistently cold so there have been no warm days for me to tell if this noise goes away when it's warm out or not. It is extremely annoying though and I can't really pinpoint what it is either.

I'm having a strange problem with my 2011 Elantra. Twice this month, I've gotten up in the morning and the hazard lights are on. The first time, I thought it was the parking lights and I'd left the door ajar but I went out and checked all entry points and everything was secure, so I checked interior lights and everything was off so I started the car, all good and when I turned it off, the lights went out but an hour later when I went out to leave for work, car barely started.
Since that time, I've paid attention to the lights. They are always off when I leave the car. This morning, lights are on again. Nothing will turn them off except for starting the car. I'm afraid that the repetitive drain on my battery will soon kill it.

I'm not sure if this is the proper operation of the disc brakes because all my cars in the past were front disc and rear drum. A search turned up nothing useful so here I am.
To me, the sensation I'm having is the rear brakes are activating before the front. I sense the rear going down before the front. I don't hear any squealing or grinding. I also don't feel any vibration while braking. Perhaps it's a sensory illusion? Or is this the normal operation of disc brakes?

I have a 2011 RX350 and recently noticed rattling sound coming from inside the glove compartment.
I think it comes from the plastic cover of the aircon filter at the back of the glove compartment. This cover seems bit loose even when installed back properly and the vibration (especially when driving over uneven roads) is causing the rattling sound.
I know it's a minor problem but the rattling sound can get irritating at times. My temporary fix is to push back the heavy owner's manual on that cover to prevent vibration.
