Prius (Gen 3) :: 2012 - Humming Noise From Rear Of Car When Parked In Garage
Jan 6, 2013
Got home from work the other day, shut down my 2012 Prius 4 and went into the house. A couple of hours later went into the garage to drop a trash bag and heard a humming/whirling sound from the garage. Walked around the Prius and isolated it coming from the bottom rear of the car. Went and got key, turned the car on, then off again and the noise ceased. What that was? Fuel pump maybe? And why did this occur?

After parking the car in the garage this afternoon I heard this motor like noise cycling on and off from the rear of the car. It was real faint but definitely noticeable. It lasted perhaps 10 - 15 minutes before quitting. What it could be?

My new prius c two has been parked in the garage for 4 hours since getting home from work. I walked out a minute ago to take out the trash and it was making a humming noise, like electric humming.

Happened to go down to garage to get something from pip about 3 hours after charge was complete and noticed loud hum coming from right rear wheel well area.
We had not had any lightning storms, electrical interruptions or anything odd; house is on whole house surge protection, and 240v evse has been working fine.
Hum disappeared when car was booted up in ev for a moment and then turned off. Hasn't come back on in an hour.

RC 350 parked in garage, 40 deg, F, for 4 hours. Happened to walk by and heard noise. Sounded like a quiet, harsh electrical hum are air escaping. Not positive but it seemed like the source was at the rear of the car and not the garage door. Noise stopped before I could trace it further. This was a second occurrence. So far no dead battery or flat tires!

I parked the little dear in the garage about 9:30 last night. I went into the garage this morning around 6:30 and I noticed how still and quiet it seemed. I then opened the garage door and went outside for a few minutes. When I came back in, I hear a low whirring sound. I went back outside to listen, but it was definitely coming from the Prius, perhaps near the back, underneath.
The hatch was open; I closed it, but the sound didn't change. The fob was in the house, and I didn't open the driver door, so it wasn't the brake pump. It lasted at least 2-3 minutes, at which time I was too bored to continue listening, and I went back to weeding and watering.

When my Prius C is in the garage for awhile and then I open the driver door to get in the car there is always the sound of a running motor - "rrrrrrrrr" coming from the engine compartment. The sound is of a motor running. The sound always lasts the same lenght of time - about 9 seconds. Then the sound stops. Since it happens all the time, I think it is part of the Prius C computer start-up software program. What is the source of this running motor. Is it the power steering motor or a fuel, oil or cooling pump?

In the last week or so I have noticed a faint gasoline smell when I pull my 2010 Prius (with 70,000 miles) into the garage and shut it down. I've looked under the hood and not seen anything obvious and there aren't any leaks onto the floor.

We have a 2013 Prius v two that is 5 months old. It has NO alarm system. This morning while sitting in our garage the car sounded as if a car alarm went off. The lights started flashing and the horn went off and on for 10 seconds or so. This happened three times over a period of 2 hours. There is no car alarm in this car.
I turned on the car to see if there were any error messages. We are coming up on the 5000 mile maintenance and the indicator for that was on. There were no error messages.

I have a 2014 ES300H that I just purchased. After driving around for a while I parked it in the garage. After it had been sitting in the garage for around 6 hours, I hear a motor or fan type noise coming from the trunk area. It lasted for several minutes and then stopped. Is that normal and what the noise might be.

Went down to my garage after the Prius had been off for at least 5 hours and heard a whirring kind of like a fan in the back half of the vehicle. I had never heard this before and it went on for at least 5 minutes then quit. My garage was probably around 60 degrees for most of that time, fwiw. Seems like the area of the battery fan but why would that need to run?

We have a 2010 RX350. It makes a noise at a strange time. While in the garage with the engine off sometimes it makes a humming noise. The noise can last up to five minutes. It sounds like it could be coming from the back but not positive. The car has not been operated for several hours when the noise occurs. If I start the engine and immediately cut it off the noise goes away. I know that it will never do this if I take it to the Lexus dealership.

2012 SE 4 cylinder. Noticed the other day a humming noise from under the rear trunk area, maybe an evap test, seemed to be running for several minutes, I did key on/off and it shut off. How often does this run, is it a battery drainer?

Tried searching, but all I found were links to fan noise in rear seat area. Yesterday my wife was in the garage and heard a fan-like noise in the right rear wheel well. The car had been parked for a couple of hours after a trip to the doctor's office. I could faintly hear it inside the cargo area when the 12v battery is located, but it was more pronounced outside. I got the key, started the car and the noise stopped and hasn't returned. I have no problem taking it in to have it checked, but I thought I'd check here before I did that in case it's normal. It's intermittent, so I don't know how easy it will be to diagnose.

My Pruis v makes a humming noise. Sometimes. Doesn't happen all the time. Don't know when it will happen. When it does happen, the car makes a humming noise. High pitch and low pitch-no longer than 2 minutes. Seems to be coming from the right side of the vehicle. It is embarassing when we have friends in the car, the noise comes on , and the friend asks, 'what's that noise' and i shrug my shoulders-i don't know.Took it to service. Manager said he has to hear it to determine what/where it is coming from. If it isn't making the noise, he can't tell me where it is coming from. Took it back today and now we have a loaner so he can drive it for a couple of days to try to hear the noise.

I have a 2001 w/94k. New tires and alignment (3k). Recently I have been hearing a humming noise which can start to be heard around 45mph which gets increasingly loud up to 65mph, and then seems to quiet down if I go above 70mph. From the driver's seat it sounds like it's coming from the driver's side rear of the car and from the passenger seat it sounds like it's coming from the passenger side rear of the car. So it definitely sounds like it's coming from the rear of the car. Bringing my car in to get looked at it is difficult with my work schedule, so I thought I would try here first. Around the city there is no noticeable sound and there has been no loss in MPG that I can tell (44-47).

Several months ago one of my 20" toyo tires was flat when I came out of work. Being a high school teacher, I thought that perhaps it was a students involved situation. That came as a surprise in that as a teacher of over 37 years, nothing has ever happened to any of my vehicles, while parked at school. Also I found it strange that they would let air out and put the chrome valve cap back on. Well, over the weekend, the same thing happened, with the car parked in my garage. So in both instances the tires went flat, I filled them back up and they held air. This happened months apart.

I just purchased a 99 GA SE, 130K, 3.4L and when we test drove it the horn did not work. Salesman said previous owner disconnected it because it "had a mind of its own". Dealer reconnected horn, I brought it home, parked it in the garage and was startled out of my sleep at 4:30 am by the distinct sound of a car horn...full blast and steady.
After a short and panicked look for the horn (couldn't locate it) I opened the driver's door and smacked, hard, the center of steering wheel. Horn stopped immediately. So, I quickly disconnected the battery to avoid further embarrassment and early morning wake-ups, and that's where I'm at.
I noticed when I tried the horn after picking up the vehicle it didn't take much pressure to activate the horn.

just came home and while inching into the garage on EV, noticed that the battery fan was on.
I have not noticed this before, except for when the battery is actually charging.
