Lexus GX 2004-09 :: Loud Failing Pump Noise From Rear Left Area When Shutting Off 2006 GX470
Nov 3, 2015
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?

My left rear suspension will leak down to bump stops unless I turn off auto suspension leveler. I can set suspension at high level turn off and it will stay that way i had set that way for 2 weeks and no leak but if I turn on leveler it may stay or it may leak down usually just left side somebody had said that my air bags were leaking so I tested it out all last month and find it hard to believe the bags are leaking if it will stay inflated a week or 2.

All of a sudden the front left lights and both fog lights stopped working. It must be a fuse or a loose connection.

Last week I had my car visited the dealer due to left rear shock leaked which was replaced under warranty...
This weekend is the first time that I took the car out for a drive... When I got home, I noticed the left rear wheel area is covered with grease... I don't know where it came from... look like brownish goo... I splashed around the inner side of the wheel and also cover part of the rear brake caliper, brake line, and control arms.
What kind of grease is this?? Where is the grease came from???
My GS is all stock... No modification.... Currently has 62K on it.

I have a new 2016 ES350 and I hear a strange electric motor type sound coming from the LT rear wheel /wheel well area when the car is off (was parked outside and was turned off 5 hours before I noticed the noise). I couldn't figure out what was making the noise, it lasted about 3 minutes after I noticed it before it stopped.

I know that you're supposed to hear a soft whining noise when starting up and shutting down the car, especially in cold weather. For at least a year now, the noise coming from my front left has gotten much louder and more obnoxious, especially in cold weather.
From what I've seen on this forum so far, I think it is the coolant heat transfer pump. Does that sound right? Or could it be a different pump or piece of some sort? Seems like there has been confusion on this issue, from other threads I've read.
The noise has gotten louder and longer, it lasts about 10-15 seconds now. Especially in the winter, it sounds really bad, I'm afraid the pump is going to fail this winter.

Having bought my 06 GX 470 only a few months ago, we're encountering 90-degree-plus days for the first time. There is an unusually loud noise from the engine that I'm almost sure is cooling fan noise. It occurs after running in the heat of the day. It's not mechanical noise, but a loud roar like that of a large truck engine. Is this typical for these models in the heat?

06 GX470 muffler exhaling white smoke for a while, now the smoke disappeared, however, a new hissing engine noise is evident. The noise increases with the revolutions of the engine and it never stops.

I am running into issues with my 3GS recently I am hearing loud ticking noise coming from the left side on the front of my car and from what most of people have told me is it might be my Axle or my wheel bearing so was wondering what the part number was for both of them and what is the best place to order these two parts from.

Have water on passenger side floorboard after a heavy rain or car wash. Seems to come from more the dash glovebox area than rocker panel. I'm aware of cleaning sunroof drains, don't think that's it.
I've removed the kick panel, can see drain, it's not too short like other post show. I realize it could be the windshield, but what about the cowl drains?
Now to the clicking noise. I hear it when AC is on recirculate, if I switch to fresh air, it stops. The temp outside or in, seems irrelevant.

I think I heard this noise before but I didn't pay much attention until a few days ago. I thought the garage door makes that noise when I close the door.
When the engine is off, whenever the last door is closed, the popping noise occurs. The noise gets louder if I close the door harder.
When the engine is on, it's the opposite. The first door opened causes the popping noise.
It's a 07GS350AWD.

I recently bought an 07 Dodge Grand Caravan and noticed that when we shut the rear door(trunk? hatch? whatchamacallit?) it makes an incredibly loud noise...almost like a gunshot. It seems as though the back glass is lifting off a bit and then slamming down. Is that something I can fix on my own?

I own a 2007 GX470. It has suddenly developed a loud whine. We replaced the power steering fluid (which we were told was filthy) but the whine is still there. The mechanic has suggested we drive it for about 500 miles to see if the noise disappears. I'm not crazy about driving it with the loud noise but don't mind. He says the car is safe to drive.

This just started happening two weeks ago but it occurred 4 times already. When i first turn the car on sometimes the back speakers pop/crackle loudly and one time it occurred that the radio was not operational for about five minutes after the loud popping occurred. I have a full platinum lexus coverage on the vehicle but the issue is the dealership cannot replicate the problem with the car. On most of the post ive seen that the issue is most likely the amp. I was wondering if there is a way to replicate the issue at hand or am i going to have to records this and show it to the dealer.

So I have an 06 mercury mountaineer it was making a rubbing noise from the rear left tire area so I replaced the bearing took the merc for a test drive and as soon as I applied pressure to the accelerator the TCS kicked off all power and it left like the brakes on the front left engaged (accompanied by some nasty grinding noises). I have taken it apart replaced the hub assembly and the cv axle, nothing looks to be out of place and everything is clean I cant think of anything else it could be..

I just picked up a 2001 F350 with the 5.4L with 200k miles. When I test drove the thing the engine sounded fine. I got it home and noticed that it occasionally has a loud knocking noise that is coming from the Left Valve cover area. It sounds like an old Chevy 6.5L Diesel ...
It comes and goes, Hot or Cold. It seems like it usually goes away when driving with RPMs above 1500 or so, however I took off with it yesterday and the noise would not go away, it seems like it might be low on power when the noise comes on, but then again it always feels low on power, so who knows.
I have changed the plugs, oil, and verified there are no exhaust leaks at the manifolds.
Here is a video of the noise: YouTube....
I dont think it is the timing chain, as it seems like its coming more from the center of the cover, when placing my hand on the cover near the timing set there is no vibration or anything that would lead me to believe its the chain.
All of my searching so far turns up 3V stuff, and little info on the 2V engines. The valve cover looks like a nightmare to get off, who have to work on these things (including me).

I have a 2006 GX470. It has some sort of automatic rear suspension height adjustment. When it is malfunctioning the rear of the car is jacked up like I have pimped it out. I use the height adjustment button but when I resume driving the car moves back into the neutral position which is not neutral at all it is jacked to the top. I had the sensors replaced once for $1,000 but within a year it was doing the same thing.
Now the light flashes to lower the back end but the back end doesn't move. I am stuck in the jacked up mode.

I have my 2004 gx470 in for service today. I have noticed that the air compressor seems to run longer and more frequent . I bought the trunk July of 2013. I have lexus plat extended warranty. Prior to this service in august of 2013 I was experiencing similar issues and when the truck was in then they replaced the rear air height control reservoir assembly . Now they are changing the rear drivers side airbag . My question is should air bags be replaced as a pair. Will I notice any ride difference since they are only replacing the one that is leaking . I would figure common sense would apply and that the air bag works or is does not.

My rear air suspension keeps dropping. Sometimes my suspension goes down all the way when parked, but not all the time. When I start the car it goes back up. It's a 2003 GX470.

My GX and I are in the south and I sometimes have to leave it parked outside all day in 100F+ temperatures during the summer. Needless to say it gets extremely hot inside and sometimes takes a while to cool down. I started using my rear AC on full in conjunction with my main AC to facilitate cooling off the interior of the vehicle. I do this even when I'm by myself because... if I'm not mistaken... the rear AC uses a completely separate unit including a separate compressor. So it seems that it would cool things down faster running both systems. Can verify that the rear unit is completely independent of the main AC system?

I'm the owner of GX 470 2006 85 k miles, facing a problem of height control failure. The problem started some few months ago while starting the car. I there was a noise behind on the height compressor. Took it to my mechanical and the noise disappeared because the compressor wasn't well fixed to the body. Since then i'm not able to adjust the height of the car. The car remains at the height low level and jumping dangerously each time i drive it inside a hole. Decided to go back to the mechanical the following code error appeared during the diagnosis: P1445. How can this code be related to the height control system when we know that this code is related to the secondary air injection system switching valve?
I decided to change the 2 height sensors located on the R and L rear side of the vehicule and the VSV locate in the engine. The problem remains. Now the dashboard keeps the green light at N and the button to raise and low the height of the car is not responding. More the mechanic can't anymore obtain the errors code from his diagnosis device.
