Prius (2010-12) :: Buzzing Sound From Underneath While Powered OFF?
Jan 19, 2012
My car had been sitting in the garage for over 5 hours after short drive this morning. I went into the garage ( without the FOB ) and heard a strange buzzing sound. After walking around I determined it was coming from underneath the rear of the prius. I opened a couple of doors and the hatch and the sound was definitely exterior not interior and continuous.
I don't know how long this had been going on but it was continuous for at least four minutes. I thought the best thing to do would be to take the car for a short spin. I went inside the house to get the FOB and returned to the garage - the noise was still there? I approached the right rear bumper to get a better listen and it stopped suddenly. I guess the difference was the proximity of the FOB?

Unlike the full-size Prius I used to have, the c seems to have a speaker somewhere under the hood which makes a buzzing/grinding noise when the car is powered by battery rather than by the engine. Is there a relatively simple way to disable this? I miss 'stealth mode' actually being stealthy. Possible to disable the EV mode 'growl'?

I just came back from a long weekend and left my 2010 GTI in the garage at home. When I returned the battery was 100% dead. Got a friend to jump it and it refused to start for about 30 minutes. Finally it grudgingly turned over and eventually started. So I drove it around for an hour, came home, turned it off and tried to start it - to see if it had charged at all. Again it turned over very slowly, and eventually started up. Seems very strange that it's so slow to charge.
So now I have it on a trickle charger and with the engine off I noticed a weird humming/buzzing sound. It seems to be coming from underneath, somewhere in front/near the right rear wheel. I waited 30 minutes to see if it would turn off once the car cooled. But it's still running. I've never heard that before and no wonder the battery died. What's going on? This is a mystery.

My '13 Prius Four has started to make a really annoying buzzing sound from the rear while driving. It can be heard inside the car but seems to be louder for passengers in the rear.

I have a 2010 model and have had this issue for the past year. When I open the drivers door I get an immediate buzzzzz sound from the engine that can last 10 to 30 seconds or so. What is this???
I believe it is somehow associated with ignition issues This last winter (in Texas) I have had to push the start button sometimes several times before the engine would startup. I brought it into the dealer and left it overnight. Of course there were no problems when they started it the next day. Anyway, I have noticed a worsening of startup problems (none in the summer) along with an increase in this buzzzzz sound. Is it just my imagination?

just purchased 2013 Persona, where I could tap power for the DVD headrests that I plan to install, when shipment arrived. I thought about looking in the fuse box, but I am a vehicle newbie. I will be installing the headrests myself, but am clueless as to where to tap for power. I want the headrests to be powered only with the key in the ignition.

If I crank up the back speakers, passengers can hear them a little better. Is it the speakers or just my car? What is the simplest upgrade to fix the sound?

There is an unbearable clicking sound coming from underneath the glovebox. Already tried removing blower motor to see if there were mouse droppings, paper bits anything -- it was clean. What this could be?

I told them that my car sometimes when I accelerate a knocking or rattling sound comes from underneath the hood. I asked them to check it. I told him it sounded exactly like an older car I had many years ago which was the result of bad gas or too low octane.
With my older car I added higher octane gas (89) and the sound went away. I had a 2011 Prius before and never had this problem and I get gas at the same gas station for years.
So the mechanic test drove my car and said they couldn't find anything wrong with it. So I'm stuck with the annoying rattling/knocking noise when I accelerate (which happens about half the time), but now I'm experiencing another problem.
A couple days later I drove to get dinner. One way it is about 7 miles. Almost the whole way the ICE would not turn off. I would be at stop light, wouldn't turn off. I pulse and glided, when I glided the ICE remained on. Take my foot off the gas at slow speeds, ICE still on.
Finally towards the last 1 or 2 miles it started going into EV when i let the foot off the gas. On the way back it ran normal. It's been close to a week now since I brought it in for service and I only had trouble one other time.

My rear right speaker buzzes when sound comes out...I thought it happened mainly in cold weather but I think it may be due to the fact that the door keeps closing and opening...

Drove my car on Wednesday morning for about 5 minutes, when I parked and turned it off, sensed a really bad and strange smell but couldn't pinpoint if it was the car, or the parking garage at home (which is underground, locked), or outside. Dismissed it from my mind. Two hours later, drove the car to work (10 minutes) parked it in underground garage. Turned engine off. Coming from hood on the right side. Got out, thinking I would lift the hood and have a look but as I approached right side of car I could see flames shooting out from underneath the right headlight (could see the flames through the headlight). Took a bit of time to find water hose in the parking garage but finally got it out.
Car is a write off.... absolutely was not sabotaged, no arsonists, nothing ..... Toyota guy from Toyota place across the street walked over to have a look, said it was a total loss. Doesn't seem like Toyota is really concerned either! I was really shaken as I feared that there could be a chain reaction of all the parked cars going up in flames. Smoke was thick, people were choking... seems that other than getting a cheque from the insurance, there is nothing I can do to find out the cause of the fire. People keep saying in various forums that nothing is located on the right..that could catch on fire.

I bought my RX350 last month and sometimes I notice a strange buzzing sound coming from the car while the engine is off. This noise can come at anytime and usually hours after I have turned off my car. It's difficult to isolate where it's coming from and can last just a few minutes.

I have a 2012 limited (non tech pkg) and I want to see if my speakers are the only ones that have a buzzing to them during cold mornings? Once it warms up, the speakers tend to be better. I have the power bass on low and I usually listen to AM radio in the morning. Kind of hard to explain but there is a buzzing rattle noise when the sound reaches a high point. It isn't a constant noise but rather dependent on the sound.

Normal to have a buzzing sound from the car while parked with the ac on? Its not terribly loud but can be heard inside the car with windows up.

I Bought a 09 with 45k miles. I haven't had no issues till my return Trip from the snow, this car is perfect for all the traffic i deal with out here. I normally have my music up loud so i may have never notice it but when I was driving with baby sleeping I started hearing a buzzing sound happen when I braked. This sound was low at the start but now is very noticeable.

I have a 2nd generation prius and up now no problems but today my car continously makes a pretty loud buzzing sound if the car is on or off. No lights are on other than the maintenance reminder light as I currently have 57000 and waiting a little longer before I bring it in for the 60,000 check up.

Each time I open the driver door, when the car is off, I hear a buzzing coming from the front (left?) of the car. It sounds like something electrical. What is it and is it normal? Assuming it's normal, I like it because it's kind of like the Prius saying hi and it reminds me I now have a unique (and fun) car. But what is it? Am I wasting battery with something I've left configured?

On my 2007 Prius, when I depress the brake to power the car on, it makes a simple, almost welcoming humming/buzzing sound. However, if I do it again within a couple minutes (for example, if I turn the car on to pull up, turn it off, and turn it on again), the noise when I depress the brake is different. When I press it down, it will make no sound for about a second or two, then make a deep 'thud' sound.

My 2006 Prius with 206k miles is making a loud buzzing/grumbling noise when I press down the brake and periodically when parked. It's coming from the general area of the brake pedal, under the steering wheel. See video for a recording of the sound:

In the past few days, our car (2006 Prius) has begun making some louder-than-normal noises while driving. I've determined that the noise appears when you turn the wheel at all to the right (note: not just making a right turn...any degree to the right past straight is enough). It seems to be constant when the car is running, but really only becomes perceptible around 30 mph. The sound is sort of like a buzzing. Maybe a grinding, but not quite. It sounds like it might be similar to this issue (2006 Engine Noise - buzzing, especially loud on highway | PriusChat), but I can't quite be sure.
