Lexus ES 2013+ :: Humming Sound From Rear Under Carriage
Dec 18, 2013
My ES350 is always parked in my garage. One afternoon, I went into the garage to get something and I heard a humming sound coming from the car. It was very hard to identify where it was coming from. It sounded like a low horsepower compressor of some sort. I put my ear next to the rear wheel on the drivers side as this was the area the noise appeared to be coming from.
This is the second time I've experienced this happening. A couple things to note:
1. The car had not been operational for at least 8 hours.
2. There was no indicator lights on the dashboard flashing.
3. All doors were closed.
4. It seems to happen intermittently and I can't replicate on my own.

2013 ES350 silver for my wife - bought 3 months ago and drove 600 miles.
About one month ago, I could hear a humming sound at the back of the car (somewhere around backseat or in the trunk). At that time, car was parked in the garage. This sound is similar to having several honey bee in that area and humming at the same time. The sound disappeared by itself after several hours.
Yesterday, it happened again. We parked the car in the garage around 4pm and did not hear this sound at that time. At around 10pm, when I went to garage to get some tools, I heard this humming sound again. This morning, as soon as I woke up, I checked the car and the sound is gone.
I am not sure if there are any other reports of similar issue for 2013 ES350, or maybe this issue is just for my particular car? And this humming sound is not always there, so I am not sure how to repeat it in the repair department. Maybe I need to bring it to delaership and just let service technician take a look.

So I know the 2013 GS (or many GS in general) have had complaints of squeaks and rattles. My GS has a couple but are very minor and only occasional.
I do have one noise that seems unusual though. When I am driving and drive over moderate bumps in the road, I hear a muffled clunk or thunk type of noise only from the rear passenger area and never anywhere else.
My car is a stock CPO 2013 F sport and not lowered or anything. Stock rims and tires. The shock does not seem to be leaking.
The noise happens regardless of if I am in regular or sport+ modes. Was going to mention it to the dealer at my next oil change and door trim replacement appointment I need to make Ina couple months.

My 2013 Sonata GLS has a noise that is in the rear of the vehicle going down the road. I rotated tires from back to front and noise seemed to move to front. I moved them back to rear so noise would be behind me. This told me the noise must be the tires or wheels. The tires are a long way from being worn out so I keep running them. I have the stock alloy wheels but previous owner put 225/40R18 tires on car. Tires size on door jam label says tire size on this GLS is supposed to be 225/45R18.
Could it be the wheels and not the tires? Another possibility could be factory lug nuts on back wheels. I read in my street rod magazine that lug taper length must be shorter than the taper length on wheel lug holes. Lugs cannot be so long that lugs hit the wheel backplate leaving the wheels slightly loose and not centered leaving a slight tire wobble when driving. The article says the lug taper much be shorter than the taper in the wheels in order to snug the nuts. I did not switch the lugs when rotating tires to front. If this is the problem rather than tires or wheels, Hyundai had a lug supplier problem.

I love the car, but had a few small gripes, including ride firmness and road noise. Well, the ride firmness has definitely calmed down a great deal over the first 3500 miles to now I find it has a perfect balance of handling vs. comfort. It's firm, but the bumps are not as jarring as those first 500 miles or so. I'm very happy with it.
The 2nd issue I hd/have, is road noise... or rather... I think... suspension noise. It's a faint droning/humming sound that I think comes mostly from the rear. You can start hearing it at 20-30mph on all but the smoothest of roads. The noise seems to be *in addition* to the very, very minimal tire noise I hear from the very nice stock Michelins. The harsher the road, the louder the noise of course.
My guess (and it's only a guess?) is that the metal bushing ('pillow ball') in the rear along with the other firmer suspension parts are the primary cause of this noise.
So I have tried a couple of things to try and counteract this noise:
1) Put D'amplifier Pro in the trunk - Got down the bare metal and put the stuff all of the place back there... Above the wheel wells also.
This did not stop the noise I hear.
2) I then put some sound deadening foam mats above both rear wheel wells.
This did not work.
The strange thing is that this noise is pretty faint, but unmistakable... however if I move my head forward (say, right in line with the steering wheel) 2 feet.... I barely hear it. But when I move back to the normal driving position, there it is.

I've noticed that when I insert the key in my 2013 F250 I hear a humming noise, if I pull the key out it goes away. What is this noise? It seems to do it as long as the key is in, but is quiet enough that you can only hear it when there isn't a lot of back round noise.

My 2010 is humming like bad.....I think it's the rear. the faster you go, the louder it is. Put new tires on - same noise.

I just towed a friends' boat 1500 kms and noticed while walking around with the vehicle running, I could hear what sounded like a slight humming or hissing sound kicking on and off in the rear, almost like an auto-levelling setup. As far as I know the Tiguan's don't come with anything like that. I don't hear it when nothing is hooked up.

This is my first all wheel drive car and same goes for having a car in which the battery is in the rear floor. My question is the following.. Whenever the car is on and radio off I hear a humming sound while at idle. At first I thought it was the SAT radio (while vol all the way down) but that was not it. Its coming from the rear right side and almost sounds like a fuel pump/something electrical. It kinda sounds like a transformer or something like that. Since the battery is in the back and there is a fuse relay box aprox. 3 inches from the spare tire, I wonder if all these electronics are making this noise? Or is my car coming to life?

Yesterday the power steering exploded on our 2008 Lexus RX 350 spewing power steering fluid all over the under carriage of the car and the garage floor. Left a trail every where we went. The loss of fluid caused the power steering to quit working. I had no prior signs of any leaks of any kind and no noise or symptoms from the steering prior to this. Had this happened on the highway at speed, I don't know what could have happened.
Loss of steering and the catalytic converters covered in oil could have resulted in a fire and or wreck. I see on line that power steering leaks seem to be a problem with many Lexus models. I have heard that a screen/filter in the power steering solenoid can clog causing the pressure in the system to go sky high blowing the rack seals. Some have said that by cleaning the filter and flushing the system that the problem can be solved without having to replace the rack and pinion.

I hear this humming sound when hit 70mph and I am on the gas. However it lasts till 73mph or so and go away!. Below is the pattern I observed;
1. On gas (accelerating), when hit 70mph (not even 69 mph) I start hearing humming sound. It will last till 73mph and goes away. Not able to pin point the source. I feel it is originating somewhere closer to transmission shift.
2. Decelerate from above 73mph and no gas given, when hit 70 I don't hear the sound. Press the gas pedal, I hear.
3. Set the cruise at 70, I hear.
4. The hmmmm sound appears only between 70-73 mph speed and while on gas.
What is this sound?. What is the source?

It is as an electronic whistle/humming. The sound is coming from the rear of the van, and no, not when it's moving, even though it still does it when moving. The only thing I can think of would be the fuel pump. Because It's loudest just before the rear tires, not after them. My fiancee has heard it twice now, when she first heard it, I didn't, but this last time when I heard it, I also noticed that the gas gauge was reading just below 1/8 of a tank.
Would like to know if it's the fuel pump or something else I'm no thinking of. And if it means I have to replace the pump.

I bought a used 2010 corolla and notice a loud humming sound at the rear when it reaches 40 mph. I figured it was the rear hub bearing assembly. I already bought a pair of Beck/Arnley 051-6262 hub assembly. I found two threads here about the removal/installation but did not say the torque of the 4 bolts behind the hub assembly. I read on the Toyota Manual that it is 74 ft-lbs. Do you think that this is too tight for a 10 mm back plate. The wheel/rims bolt torque is 76 ft-lbs but the nut is about an inch length. It is almost the same torque for an inch nut compared to 10 mm back plate. Is 74 ft-lbs right especially for an aftermarket beck/arnley brand? On the Toyota Manual, the 2003-2008 Corolla 4 bolt torque is 45 ft-lbs. The 2010 is 74 ft-lbs???

So today while driving my '98 Mercury Grand Marquis home I noticed a leak was coming from behind the rear right tire.. Or I'm guessing it's a leak ? But it's kinda like a grease substance and it sure does smell bad! It's all over the backside of the tire and muffler (probably why it smells).
While driving it there is a low humming sound? Best way I know how to describe it and if I go over 60mph it gets increasingly louder.. After looking up some forums online I came across that it could be a possible wheel bearing or maybe a bad axle problem?

Finally got the Tech to acknowledge the Humming/Groaning from the Engine as I sat behind the wheel at my 5000 mile service visit. His response was that the sound we were hearing ( at start-up) was "NORMAL"
The RX drives and sounds fine after that mileage, but many times my destination is less, and I feel like I am driving a reject.This has persisted since new, @ frigid and high temps; as we approach 7500 miles.
Engine sound varies in pitch when acceleration increases the RPM's ?

This is a first for me. Came in last night after my 140 mile commute and pulled into my garage and turned off my car ('16 IS350F). This morning(approx. 10 hrs.later) I went into the garage and heard a humming noise. I thought it was the refrigerator, but as I walked around the back of the car,it was obvious the noise was originating from the right rear. It sounded(to me) just like the fuel pump running,but that made no sense as it isn't on the "hot" battery bus...ie: it doesn't run until the accessory power is provided. I got in the car and cranked it....let it run for a couple of minutes and shut it down and the humming stopped.

2007 GX470 - Just noticed a distinct whining/humming sound similar to tire hum you would have with aggressive off-road tread tires. Seems to come alive around 20mph (or at least that's when I can hear it) and gets louder with the increase in speed. As I slow the sound goes away. Only does it while moving and not in neutral with engine rev.
We bought the car at 59k and it just hit 70k . Only oil changes, tire rotation have been done since we bought it. The tires were new when purchased so they have about 10k on them. No noise when we first got the car so I tend to think it's not related to the tread.
I was planning to do the front/read diff and transfer case drain/fill. Wondering if that may be the cause.
Something else - at low speed in tight turn (i.e. backing out of garage, pulling into parking spots) I do feel some roughness - almost like the differential is locked. Not sure if that is an indication. Was thinking it may be a wheel bearing but there is no clunking when turning.

So there is a loud humming sound as I would describe, coming from the passenger side glove box when I turn my fan to run at high...

Checking my garage before going to bed last night and hear motorized humming coming from rear of the GX. I slide underneath and it seems to be coming from the spare tire area. I started the engine, then shut it off and the noise went away. The noise reminded me of the air suspension pump on my old Denali, but my Gx has the standard suspension.

Our SFS LTD started this high pitch constant squeaking sound in the back of the hatch/cabin. We can't figure out where it's coming from. It doesn't seem to have any relation to the suspension (going over big bumps), and occurs on regular driving on flat terrain or regular street bumps/turns, city/highway...
We figure something is rubbing in the back or perhaps its due to a bulletin from the 2008 SFS (welding fix in the rear panel)?

I have a 2 month old 2013 Prius v, recently I’m hearing a squeaking sound, a sort of rusty door hinge sound when staring the my Prius v every morning (or after parking it for around 7-8 hours or so) coming from the rear axle or wheels. What causes it or what I can do about it? I have brought it to my dealer but it seems they don’t have any clue on what is happening (or they just don’t want to do the warranty on it).
