Lexus GX 2004-09 :: Loud Whooshing Noise Occasionally When Parked - Rear Air System Malfunction?
Sep 30, 2012
My wife's 04 GX deflates sometimes when we park it, you can clearly hear a loud "whooshing" noise occasionally when we park it in our garage. The rear then goes to the lowest possible setting, it looks odd laying that low. Because it's not my car, I don't know if it always did that, but it seems "new" to me.
The deflation sound is coming from the rear mounted compressor on the rear driver side, I went under the car to investigate. It also appears that the air bags themselves aren't leaking, I raised the car to the highest setting, and it stayed there without the compressor kicking on or any leaking noise.
My guess is maybe the sensors need to be replaced, the thing is, I don't want to "shotgun" parts at a problem and spend $500 or so dollars on new sensors to experiment. How do I know the rear is behaving correctly?

I have 3 sound bytes/videos. Probably best to listen with headphones or decent speakers to get the full effect. The issue has gotten worse. Seems to be worse especially in the a.m. when cold.
When I accelerate fairly quickly, not wide open, there is a weird noise of whooshing air, his or escaping air etc. It could be described as some type of whirring noise too.
I can let off the throttle and push slowly into it and it goes again. Only happens under a decent amount of engine load. Doesn't seem to matter what gear as long as it is under the same type of engine load.
It is coming from the passenger side engine bay as far as I can tell since I'm driving.

Occasionally, when I start my 07 I hear a loud zip noise that seems to be coming from the front of the car somewhere. I know it's kinda tough to pinpoint. Something running against the teeth of plastic gears comes to mind.
I should also mention that it happens immediately after the engine has started, about the same time the self leveling headlights start to move.

Several times I have gone into my garage to hear a weird noise coming from under the rear of my car, almost sounds like a small air compressor, like one you would plug into the cars power source. If I start the car and immediately turn it off the sound stops, otherwise it will continuously run. The sound does not always present but when it does the car is completely off and the key is not anywhere near it.
Here is a video, you may have to turn up the volume, the video is dark as it was shot from under the car. [URL] .....

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?

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.

C1241 is low voltage warning and C1223 is an ABS control system malfunction.
Are or could these be related? Where should I start to troubleshoot the issue?

Over the last few weeks I've been hearing what sounds like a failing pump of some sort when shutting off my '06 GX470. The sound lingers for just a moment after the ignition is cut off, and sounds like a loud, very fast tatatatatatatata. It doesn't always do this - sometimes I don't hear anything. I've been commuting in the GX for four years and I've only been hearing this intermittent occurrence over the last 3-5 weeks.
What this might be? Fuel pump? Air leveling suspension pump?

I hear a 'whooshing' noise at low speeds (parking garages, exiting my home garage) when I lean my head forward.
The noise seems to be coming from above and behind me. I don't use the rear doors that often right now (no kids yet) and I verify that windows are closed?

Alternator on my 2006 GX failed, caused battery to discharge and vehicle stopped. Alternator was replaced, battery (was new) is testing fine. All electronics and indicator lights normal except Nav system. Display reads insert proper disc. I have ejected and reloaded disc multiple times, no change. Disc is OEM, one release back.

After owning the truck for a little over a year I figure it's time to fix the little stuff staring off with the rear door. When pressing any of the 3 buttons to open/close it I get it to work 50% of the time. That being said, I can't pinpoint a specific bad part.

We continue to be delighted with our 2008 V8, it's like having wings. I drove to England across France from Switzerland for 100 kms recently, had a wonderful day there and back. But when I play our iPod with WAV files through the sound system there is some distortion on loud notes, even at low volume. Strangely, when a young friend attached his iPod and then replaced mine, it did not distort. There is no distortion when using the CD changer or the Hard disk drive, but I prefer the large choice and full files on the iPod, given the great quality of the standard sound system. Now the sound distorts again when playing music on the iPod, and even if i detach the cable and replace it any number of times there is little difference.

The sound system in my 2008 LS 460 suddenly stopped and a loud thumping noise comes up in all speakers even if the radio is turned off. There is no music at all only that loud noise. Bluetooth does not work as well as command voice and the GPS guiding system. I had to remove the fuse to stop the thumping sound. To answer my telephone I must pull on the side of the road and turn off the motor. Car dealership said that it is the first time they see that. The car is scheduled to be looked at in a couple of days.

Couple days ago I took out the factory air box and cut the bottom out. I also cleaned my K&N filter at the same time. I cut the whole bottom edge to edge up to about 2" from the flapper on the motor side of the box. Re-installed and everything is tight. I drove the car and noticed a LOUD or what I consider loud noise from about 3,000rpm to redline. I am thinking it could be just the additional air being sucked from the air box. However its much louder then I would expect from a CAI. Does a CAI make a loud difference? I noticed a increase in performance so I know its working. Also, it could be described a a light, smooth sounding exhaust leak. But I am susceptible since this problem was not their prior to the intake mod.

Was running the car at about 4500 rpms in 5th gear. All of a sudden lost power and heard a loud whooshing/ hissing of air which sounded like it was coming from under the front passenger side of the car. Lost about 50% of power in all gears. What I screwed up and broke?

2006 Chevy Silverado 2500HD Duramax.
When I park it with the front end elevated even just slightly higher than the rear the fuel system loses pressure and I have to pump it up using the manual pump under the hood. This usually happens after 15 - 20 minutes of park time. When it is parked flat it usually will last hours or more, and if I park it with the rear elevated over the front then it doesn't seem to have a time frame. in other words it does not lose pressure at all.

My wifes 2006 mountaineer V8 overheats. She says itll only do it sometimes after the truck has been warmed up. She will come top a stop and the temp will spike and she will get a warning light then it will go back to normal and be fine. When the temp spikes she hears a loud whooshing or whirling sound coming from the motor which I supposed is the fan? Could it be a bad thermostat or waterpump?

Yesterday there was a huge rain. Our 2009 Prius couldn't park under the carport (on slab) as we would have had to drive a ways through really soft water-logged ground in front of it. So the wife left it parked on our circle drive driveway, which stays harder than the ground elsewhere, as there is still some caliche left on it. So an inch or so of mud was on all the tires and even more mud on wheel wells. We are on a slope, so I am sure that water never got up to the underside of the car.
Today I go to drive it---fortunately it was not stuck---but have the sonalert tone going off, the red brake warning light on, the ABS light on, and the VSC light on! I was hoping it was just an accumulation of mud blocking a wheel sensor, so I took it to the car wash and washed the inside (primarily) and outside of the wheels off. Then realized that mud is non-ferrous,so it shouldn't block a wheel sensor signal anyway.
I do have an OBDII code reader.....might it be able to read brake system trouble codes on Prius? This surely is induced by mud or moisture.....what would it likely be? It has always been perfect as far as brakes until yesterday, when it got a huge amt. of mud on tires. Could maybe water accumulate in one of the sensor harnesses, effectively shorting it out?

When the car is in a situation where there is a twisting force, such as entering an inclined driveway from an angle, a loud POP is sometimes heard from the rear of the car. The intensity of the POP varies dependent on speed and angle of incline, higher speed/greater incline/decline produce a louder POP.
