Lexus GX 2004-09 :: GX470 Air Suspension Often Deflates To Axles And Stays There
Feb 13, 2013
I have a 2003 GX 470, the air suspension often deflates to axles and stays there. Ride is unbearable, I removed the rear height sensors and used an ohmeter to test them and they seem to be working fine (ohms change as I move the pivot arm, goes from 423 ohms to 3.3 K full stroke on both sensors) It will deflate to axles and there are no flashing lights and the manual height switch doesn't do anything when I push it, it just stays in N. Every few days the suspension will start working and air up and ride fine. What else could it be besides sensors or is it the sensors even though they seem to be working fine. Could it be an adjustment on sensors. Where is the height control exhaust valve located? Once it airs up to normal can I just disconnect the exhaust valve so it cant deflate?

I have 228,000 miles on my wonderful GX 470. Love it!! Very Few Problems. My Airbag Light on the Cluster stays ON sometimes and sometimes is OFF. There is no consistency. I will be driving and the light will come ON and stays ON. And then, it will stay OFF for few drives. Why the light would sometimes come ON?

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.

I have a 05 gx470 and I was having trouble with the rear staying bottomed out and not pumping up. I replaced both ride height sensors. Nothing changed until about 1 hour of driving the compressor kicked on. it road better but still bottomed out some. So I raised the sensors about 5mm. it road great for about 10 miles then went back to riding on the axles. No compressor activity. Also when the compressor is not engaging the push buttons do nothing with changing the dash from H-N-L no matter when you push it. If you hear the compressor running all the buttons will work just fine. I have a useless car because it is not safe to drive when its riding on the axle bump stops.

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.

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.

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 believe my GPS is out of date. The DVD says North America version U20. Data version 05.1. Is this old? Is the newest DVD going to really work for me or can I buy last year's model?

I own a 2004 lexus gx 470 and I am having some audio issues. The stereo system is the standard Mark Levinson speaker system. When i turn on my car, I can cycle through the different radio stations and cds, but there is no receiving audio coming from the speakers. I think it may be an amplifier problem, but i also don't know where to locate the amp or how to get my radio to work again. Also, I have tried holding the audio button while cycling my taillights on and off 3 times, but nothing shows up on the screen. My radio has not been working for about a year now.

This is a problem that started a couple months ago, and I've taken it to two separate mechanics. Neither knows what the problem is. Basically, most times I try to start the car (~75% of the time), it cranks, and keeps cranking, but does not start. I have to pull the key back, and turn it again. Then it starts no problem.
Not fuel related, as pushing the gas while it's cranking and not starting does nothing. It's not regular either; sometimes it starts first try on a cold start, sometimes not. Sometimes it starts first try after driving for a while, sometimes not. It's a 2004 with 130k miles.
Interestingly, I am pretty sure this started when I got a new key. The physical key shell snapped and separated from the blade. I ordered a new one, and put the old transponder into the new key shell. I haven't had any sort of anti-theft problems afterwards (unless this is one).

So the other day I was listening to the radio, and all of sudden no more audio.. After some troubleshooting, and some reading. I am thinking it's the levinson amp. I have a few questions:
First where is the best place to buy a replacement.
I assume it's the piece under the passenger seat and it's as simple as undoing the bolts and swapping out the cables..
I did run the diagnostic with the holding info, and flicker the lights and everything came up as "ok". I just need to get audio going in this thing again for as cheap as possible!

2007 GX470
Display screen blank- radio and AC work but cant control on touch screen (its blacked out), tried a few tricks that others had suggested
like hold info and cycle lights 4x
removed positive battery cable and replaced
held menu for a minute
etc etc
Gave up. Went to dealer expecting a unpleasant $$ (buy a new nav screen) type of surprise. nope! service writer pulled it in to the shop and ....
Disconnected the NEGATIVE battery cable. Fixed it right away and didn't charge me a thing (shouldn't have anyway) He said that sometimes the computer just gets scrambled and shuts itself off as a precaution. So if you nav screen is blacked out and unresponsive give that a try.

I was using the12V power outlet to power a small air compressor to a small air tank. Had to answer a phone and forgot about it for a while. When I returned, the air compressor was not working. I figured I either blew a fuse or fried the compressor. I pulled the 12v plug from the power outlet and inserted it in the cigarette liter outlet and the compressor still worked.
I then plugged my radar detector into the 12V outlet and it did not work.So I figureed I blew a fuse. I pulled the 15 amp fuse from #54 but it looked good. To double check I swapped this fuse with the 15 amp fuse for the rear wiper and the fuse was fine.
So I am thinking the 12V power outlet socket must be bad. Isn't that why we have fuses -to protect an expensive part with a cheap one? Is this an easy DIY job?
