Lexus IS 2014+ :: Buzzing Noise From Rear When Vehicle Off
Jul 16, 2015
This morning I heard a "strange" buzzing noise coming from the rear of the vehicle and I don't know what it is.
As background I drove my IS250 for about 1hr yesterday and parked it for the night around 10pm inside a garage. This morning at around 7am (9 hours later), I came down to the garage to hear the buzzing "fan" noise. I am not sure what it is. The vehicle was OFF. I managed to record the noise.
IS250 Buzzing noise - Car OFF for 9hrs - YouTube ...
That said, the buzzing noise couldn't be something left on overnight... since the battery was fine. The car proceeded to start just fine. What do you think it is? Can it be some sort of fuel vent pump or something?

So I went into my garage last night to shut the door. I heard a slight buzzing/humming noise coming from the car. I narrowed the noise to under the truck of the vehicle. It sounded like a fuel pump was running. I don't know when it started, but it was about 5 hours after the car was driven last. After a little research, I found this in the manual page 8:
"Approximately five hours after the engine is turned off, you may hear sound coming from under the vehicle for several minutes. This is the sound of a fuel evaporation leakage check and it does not indicate a malfunction."
I started my car and it stopped after that. Could this be The case of why some people have dead batteries on the 2014? Maybe this runs to frequently or stays on too long?

2015 IS350 AWD ... Lately I have noticed on a cold start that when my idle is between 1000-1500 rpms, there is a slight buzzing/humming noise. It goes away if I rev the rpms past 2000 rpms and also when it drops under 1000 rpms. It's almost like a droning noise. I can hear it inside and outside the vehicle when the rpms are in that range. I feel like the noise is made at a certain frequency and it causes a vibration to occur.

So I've been hearing this vibration rattle or buzzing noise... on rough roads and overpasses in southern California. I've uploaded a video clip. At 4 seconds I enter the overpass... and you can hear the buzzing noise from 6 seconds to 9 seconds, you might need to raise the volume.
Is this a normal noise from overpasses? My old cars didn't do this. Also I can't tell where it's coming from, maybe the rear upper area or who knows, could be the license plate for all I know.

Experienced a buzzing noise from left rear wheel well. I have noticed it a couple of times after the car has been parked in the garage and sitting for awhile. The dealer said it is normal and the auto suspension readjusting. However, it will continue for a long time but will turn off if I start it up. I am concerned this normal leveling will burn out the motor in do time. We have a 2010 premium.

I have a 2015 IS250 Base with TRANNY PROBLEMS
After 185 miles on the vehicle, I reported the problem to Lexus and the Tech that test drove with me said I was hearing things. Apparently there was a humming noise coming from the transmission.
The noise became evident and consistent, took it back in again, the Tech says its normal and DI engines make a lot of noise.
After six months and 2700 miles the noise became annoying, Tech said they will look into it and confirmed it is unusual. Test drove about 5 other new 2015, used 2014's and no humming noise present.
Engineers made two trips over a five week period from Cali. They changed the alternator, which at first they thought was the problem, then they started looking at the fuel pump on the engine, then they swapped out a tranny from a loaner and the noise disappeared. They took out the loaner tranny and ordered a new tranny and installed it.

The last two mornings I have gone into my garage and have heard a faint "buzzing" noise that seems to be coming from the rear of 2013 RX350. Given the location of the noise, my first inclination was that it was possibly the fuel pump running a cycle for some reason. But when I heard it for the second day in a row, I figured it would be wise to ask if this is normal or something I should take up with the dealer?

I have a new 2015 Elantra GL Manual that seems to have an E-brake that does not feel like it holds the vehicle solidly. I know that the E-brake is probably a small drum brake setup in the rears only but feel like an adjustment can be made to really ratchet that lever up better?
The other issue is a humming, buzzing, vibrating sound in the front passenger side area at hwy speeds. Maybe a vibrating splash shield or rock stuck under the shield?
I was also able to get some new alloy rims for a good price (FAST brand) from the dealer (believe it or not). They aren't the sexiest things to look at but I needed another set of rims anyway to winters and the price was better than plain steelies. I'll probably use the OEM steels for winter now and alloys for summer. The alloys are a little wider at 7 inches than the OEM 6.5 inches and much lighter. I plan on getting Michelin X-Ice soon.

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.

I've noticed a couple of times with my 2014 Luxury edition a noise coming from around the spare tire area when the vehicle is parked and shut off even for several hours. Could this be the air shocks?

Any time I've been driving for 10-15 minutes, my foot starts to feel like pins and needles because of a buzzing/vibration feel from the gas pedal. If someone were to drive in stop and go traffic for 5 minutes, they wouldn't notice it. However, it takes me 30 minutes on a highway to get to work and my foot is on the gas pedal the entire time. However, within several minutes of having my foot on the pedal, I get this sensation as described above and it gets so annoying that I almost don't want to have my foot on the gas pedal any more.
I did change my tires when I first got my car with Michelin tires but kept the stock rims. I did this so I can save the run flat tires for when I return my vehicle after the lease is done. I highly doubt its from the tires as there are no vibrations or other feelings in the steering wheel or seat. The car is otherwise smooth.
However, I feel like there are these buzzing vibrations in the foot well of this vehicle. What it could be? I know these gas pedals are metal but I find it hard to believe that would be the reason.

I have noticed since I got the car( 6 months ago), when ever I have passengers in the back seats i hear a clunking noise coming from the right rear suspension area.
( I don't know if this is from the suspension or not and I only notice this noise when there are passengers in the back). The clunking noise is really annoying.

For the last couple of weeks I've been hearing a weird noise towards the rear end of my car when I accelerate, seems like it's worse when I'm going uphill, sounds like a box of shoes moving freely in the trunk of the car. At first I thought it was something in my the trunk but I have nothing loose, the spare wheel and all attachment are pretty well secure. The only thing that I can think of is that the dealership installed the F Sport exhaust to it, but not sure if that should be making that type of sound. Sound is pretty low but it still manages to upset me, specially since my car has less than 3k miles on it.

Lexus IS300... The sound is coming from the rear. It appears to be left rear. It comes and goes, but seems to intensify when accelerating and right turns. It's annoying. It's embarrassing. I have taken it to several different shops and nobody seems to be able to figure it out. What it could be?
See the video below to hear the noise : [URL] ........

There is a buzzing vibration in my car over rough roads and it seems to occur only when it's warmer than about 50 degrees. I know that may seem odd but I've been paying attention to it for about 3 weeks. It only happens when the road is rough e.g. has a lot of cracks in it or has a lot of granite in it. The sound is like a bee. Now that it's colder here I notice that I can't hear it on the same roads when it's 50 degrees or lower. It's hard to pinpoint where the sound is coming from too. I know someone posted that a clip was loose from when they had tinting done but it seems my case would be different -- like something (nut and bolt?) is expanding and contracting. I'm not sure I want he dealership to take the car apart trying to find it. I can live with it but it is irritating as I often drive with the radio off and the car is silent and solid otherwise.

So I purchased my 2015 Lexus IS 350 AWD F-Sport back in October and experienced the following issues:
1. Brake squeal
- seems to occur when reversing out of a parking spot for example, so annoying and extremely loud, makes it sound like my brakes need changing
2. Bluetooth Radio
- there are times where my phone connects to the radio, plays music off my iPhone but then it sounds like the singer is slowly dying i.e.: the type of sound you used to hear when a walkman's batteries would be dying and needed changing. Happens sporadically
3. Gas tank lid on side of car won't close fully
- this happened just this week. I couldn't close my gas lid, no matter what I did. I managed to get it closed today after starting my car, wonder if its related at all to power/engine being on etc?
4. Buzzing in gas pedal resonates through foot
- this one is still driving me insane. Drive my car for 10-15 minutes on the highway and your foot feels like pins/needles from the buzzing sensation from the gas pedal.

The sunglass bin, in the overhead console that includes map lights and sunroof controls, has been buzzing since a couple of weeks after I bought the vehicle. I've taken it to the dealer several times, but they can never reproduce the issue. Today, I decided to take a closer look myself. I removed the bin and then drove for a bit; the buzzing noise continued, even with the bin door removed. Therefore, the buzzing must be coming from the plastic trim around the sunglass bin.

I just got a 3rd gen IS 1 month ago, but the last 3 weeks there is a rattle noise coming from the rear door on the driver side. I went to lexus twice now but they were unable to fix it and they told me to wait till the car breaks in.

2010 F150 - 5.4L ... I encountered a disturbing chatter/buzzing noise while towing recently. I have not towed a lot with this truck but recently bought a 8.5x18 enclosed car hauler and have towed the trailer about 3000 miles so far. Twice I have experienced a chattering noise from the transmission under very specific conditions. Was traveling on a long flat road at about 70 MPH in 5th gear at about 2100 rpm when it started. If I let off the noise would instantly go away.
If I accelerated and went into 4th the frequency and tone of the chatter would not change with either RPM or speed, however, when I let off it would go away. It is almost impossible to reproduce because it has to be flat. It did once start to chatter in 4th when I was pushing a strong headwind at about 70 MPH and 3000 RPM.

I just saw a video of an IS350 and the mirrors folded in when it was parked and locked. The model was a hybrid, so I am not sure if that is a different option. I am looking at the IS 350 F Sport awd. Just curious what extras it will or could have.

Last week, I went out to my garage to investigate a motion sensor event that shouldn't have occured. It was about 3:00 in the morning. The Prius had been powered off for probably 8 hours or more.
