Lexus LS 2007+ :: Electric Motor Noise That Comes From Rear A Few Seconds After Shut Car Off
Nov 14, 2014
I have this weird electric motor noise that comes from the rear a few seconds after I shut my car off (I don't have the leveling air suspension). I also hear it in the engine compartment on occasion when the engine is shut off (I've heard it hours after the car is off). It lasts for a couple of seconds and it's gone. I do have the car set on auto ebrake. That's the only thing I can think of causing the noise...like the cable loses tension and the motor tightens it, but I don't really know.

I have a 2013 ES 350. Last night about 5 hours after the engine had been turned off, we noticed a strange noise coming from under the rear of the car? It sounded like a small electric motor was running. I started the car and turned it off. The noise had quit. This is actually the second time this happened.
I got under the car to try and determine the exact location of the noise, It sounded to be coming from the gas tank area. Could it be a fuel pump kicking on?

My 2009 LS 600h:
I park the car, i turn it off, the steering wheel goes to park position. Then, when i open the door i hear a sound like a electric motor.
My GS 450h did exactly the same. Auto handbrake on or off makes no difference.

I have a 2009 Kia Sedona that is in great condition. I noticed an odd thing today. After shutting the car off and letting it sit for an hour or so, I came out to my garage and a heard a weird whirring noise. I couldn't place it at first, but I eventually realized it was coming from the Sedona. The best I am able to locate it is under the rear, near the back axle. It doesn't sound louder on either side of the vehicle.
The noise itself sounds like a small electric motor moving. Almost like in those old movies when a robot would move his arm. It happens anywhere between every 30 - 60 seconds, but not at regular intervals. Right before the noise happens there is a light click, which I'm assuming is a switch that's powering the thing opening.

We've owned our 07 since purchased new in 06. It's always made this noise, but it used to be for a short period of time (1-2 min). Now it goes on and on for 5-10 min. It sounds like it's getting "stuck" and starting the cycle over.

After I shut off my truck, about 5 to 10 seconds later it sounds like a compressor or small motor is running, and it runs for about a 50 to 60 seconds. It seems to do this even if i turn the ket on and off, sometimes. What this is.

So recently I was driving through highway 17 with 4 people and we'll my 07 Prius was slowing down like never I eventually smelled a little burn but I ignored it I just though the engine was working a bit to hard. Recently I noticed that on the energy screen it only shows that the battery is getting charged it sometimes used the battery to the motor but not often. I did notice though that I run with electricity more when I'm in the city. It's quite weird it's like the electric motor doesn't work on the freeway.

I have an 03 Santa Fe, 2.7 l AWD. Recently I've begun to notice a whining almost electric motor like sound coming from the rear of the engine. It get more noticeable the longer the trip. The weird thing is that it seems to respond to throttle input more than speed. If I'm cruising at say 65 I can ease off the throttle, reapply the throttle enough to increase RPM but not speed and hear it. I've had the differential, brakes, bearings checked. My mechanic has had it in the air 4 times and has spent atleast 4 hours on two occasions trying to find it. He can hear it. My thoughts are that it could be the Fuel Pump, or the exhaust.

I went out to my garage a minute ago and heard my C making a weird noise. Like a small electric motor running. I finally pinpointed the sound to the bottom of the car back towards the fuel tank. At this point I thought my fuel pump was powered up because it sure did sound a little like that. I was saying to myself at that point that I am sure glad the car is still under warranty. So I went to get the SKS fob to start it up, hoping the sound would just go away. While sitting in the car prior to starting it, it occurred to me that maybe I should remove the fuel cap first. While opening it a slight "whoosh" occurred blowing fumes in my face when removing the cap and the farting promptly went away. The tank is down to two segments level wise, it is cooling down this time of the day, but I did get back from a long drive a few hours ago, so I can't see how the fuel or vapors were expanding enough to release through a pressure valve. So if you car is farting, remove the gas cap first before panicking.

A quick question, currently an observation.. but a concern. we purchased our 2012v used at 55k miles.. She's running great, MPG's are above rated expectations. (ave 47.2 so far) We are currently @ ~59400 miles.. So, all seems OK w/the exception of this strange noise.. I'm familiar with the typical prox pulse sound at low EV speeds.. and this noise is not that one.

Just walked by the back end of my new Prius III and heard what sounded like a electric motor running from the general area of the exhaust pipe at the right rear end of the car. This was about 5 hours after I last drove it.

I have a 2014 Lexus ES300h. I just started noticing that after 2 to 4 hours after turning the car was turned off, I am finding what sounds like the electric motor running. There is a buzzing sound. I can turn the car back on for a few mins and then back off, the electric buzzing sound goes away.
Since owning the car, I've never found the car buzzing. It sounds like the electric motor is charging the batteries. Do I need to have this checked? I have 28k miles on my car and have never had an issue.

Last night when I went out into the garage, I heard the sound of a small, lower RPM electric motor. After walking around a bit, I found it coming from the underside of the back of the Camry. I got in and turned the key to the "on" position and it went away. The car had been parked for about 5-6 hours. I've never heard this noise before.

Started getting a noise a few minutes after startup. I can hear it click on and then it sounds like a loud electric motor/pump/fan type noise. Starts pretty loud, then gets quieter (but not gone) after 30 secs. If I turn off the engine, it stops and if I immediately restart, it's gone for a couple minutes.

I have a 2007 Jetta with 75k miles on it. What I'm running into is that out-of-the blue, the car will not start. Generally, it turns over, but never starts. One time, it started but shut itself off after 3 seconds. Warning lights that flash are the steering wheel indicator and sometimes the traction control and immobilizer lights. I replaced the battery hoping that that would fix it, but it hasn't. Notably, the engine light is usually on when starting and goes off after 3 seconds, but now it doesn't go on at all.
The issue first started a few weeks ago, but I could successfully start it 15 min later. No issues for 2 weeks, until the traction control light came on and stayed on while driving. Nothing for a few days, and then suddenly could not start again (tried over a period of 3 days). Towed to a shop, where it started after two days.

The headlight beam height can be adjusted from inside the car. But even when not fiddling with the dial, I hear an electric motor sounding noise from them time to time, just a short <1s whirring sound. I listen with the bonnet open and I'm pretty sure it's coming from the headlights. Is this normal? is there any way I can stop it?

Noticed that motor turns over for roughly 3-4 seconds before starting when their GX has sat for awhile in well below freezing temperatures?
It's not slow turning over just takes a little bit longer to actually catch and start.
When the motor is warm or the outside temperature is closer to freezing or above I find that it turns over for no more than about 2 seconds before it starts.
I am thinking the longer turning over when cold is a good thing since the motor is starting to pump oil when it is turning over and allowing the internals to get lubricated before starting and revving.

Well, I will be taking the Touareg in for at least the 3rd time regarding this problem. The first time they told me it was a bad battery, so they replaced that. They also gave me a new battery last year, so I am on #3 now. I specifically asked if it was the alternator cable as my voltmeter had been reading anywhere between 12.5 and 14. They said it was just the battery but did keep it an extra night just to be sure the service manager could take a look at it to verify.
The second time I took it in they reset some electrical and reprogrammed some module...I don't have the ticket in front of me.... Again I asked about the alternator cable and again they told me now.
Well, for the past week or so the consumers have been shutting off almost daily. My wife normally drives the car but today I was out in it and it happened twice to me. It seems like it happens more so when it is cold, but I might just be crazy.
I am going to take it in. Is there anything else might be, other than an alternator cable. I truly love this car, and when I look at any other SUV, except Range Rover (can't afford one), I fully believe that the Touareg is better in every aspect, with fit and finish better than any other. This electric consumer thing is starting to get a little obnoxious though.
