Lexus GX 2010+ :: 2006 GX470 - Automatic Rear Suspension Height Adjustment
Jan 18, 2011
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'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.

I took my 2003 GX470 for service (not a Lexus dealer), which included rear brake pads. After picking up my car, I realized there was a serious malfunction with the rear air suspension, and my "car height" was no longer working. I took it back to the mechanic immediately - he stated that the rear air bag deflated when they put it up on the lift (which is normal). However, they couldn't get it to inflate again, so had to order a new one. I'm wondering if this is the mechanic's problem or mine (the car has 101,000 miles on it).

I own a 2004 GX470 and am recently having issues with my rear airbag. The height control is inoperative and the bags will not fill completely and lift the rear.
I went under the car and found the bumpstops are a few centimeters off the rear axle.
What could cause the height control to not function? Could it be the height sensor, airbag, etc? I could hear the air compressor turn on so do not think that is an issue.

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 '11 Ltd. r.v.mirror has the backup camera, and is attached to the windshield 2 inches below the top, order to clear the GPS, antenna, theft, ( ? ) hardware..... I'm over 6 ft. and it seems to needlessly block too much of the front field of vision,......anyway, I've tried to adjust it as high as it'll go and it's still an inch from the top. Is this as far up as these mirrors can be set?

The owner's manual for my 2010 Camaro states that the passenger seat height can be adjusted by pumping the handle used to slide the seat forward and backward. However, pumping the handle does not change the seat height.

For those lowered, how did you go about getting the beam height back to stock spec?

I've had the stiff ride issue with my 2005 gx470. Took it to three lexus dealers and finally the vehicle is fixed. Hats off to Lexus of Maplewood, St Paul, MN. Their shop foreman persisted and found after several days troubleshooting; a speed sensor was the culprit. My ride is much smoother over speed bumps without the need to cycle through the height adjustment.

I am having a problem with my rear suspension. The indicator lights on the dash (for the rear suspension control) are working correctly as are the controls on the center console, however the rear of my vehicle is stuck in a high position.

Is there a way to re-program the tailgate/rear door height? Or even manually adjust? Just purchased a 2012 RX 350, and my garage is about 4 inches too short. Now I realize I can disable the electronic lift, but it's a shame not to be able to use this feature. I'm sure others have had this problem, but I've googled with no success.

Perhaps a strange question, but is there any way the pedal height can be decreased. On my 2010 LS 460 it seems to be higher than on my previous 2005 LS 430 to the extent that I lift my foot off the accelerator pedal and miss the top of the brake pedal. It's happened often enough that I've been wondering if it could be reduced an inch or so.

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.

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?

So I can successfully set the height at which the tailgate should stop, and in fact, the "power" function seems to stop there. But once the motors stop doing their thing, it just keeps slowly creeping up, as though the gas pressure in the struts is too strong for the tailgate weight. It's brand new, so this wouldn't be surprising. But is that the way it's supposed to work? If so, what's the point of setting a height at all? In my case, I want it top stop just a couple inches before hitting my garage door.

My 2007 Prius drivers seat height adjustment is not keeping steady. That means when it's adjusted to the highest level slowly it comes down after couple of days.

I have been using it a lot over the last 2 years since I bought my 2005 3.0 TDi. Love the car, have had a few issues but nothing major. I do now have an issue with the seat belt height adjustment in the passenger side. It will go down, but not up....slightly annoying as you can imagine. When I press the button to raise the belt, nothing happens. Seat are 18 ways ventilated massage seats.
