I have a 2004 LS430UL and everything is stock. Sometimes the rear of the car will ride high and very stiff(bone jolting) and other times low and smooth. Also, when parked at times there will be 4 inches visible clearance between the tire and the wheel well, other times the parked car will be sitting 6 inches lower.

Is this a faulty sensor? The car was Lexus certified.

 

Take your car to the dealer & let them check it out for you

 

Sounds like something computer/controller related. I would definitely take it to the dealer. There is no way an amateur could diagnose and repair this on their own.

 

That sounds similiar to my problem, I have the data controller system. The dash will beep and tell me height hi, and start to adjust "hi". But it only starts to adjust on the driver front size only. I'm not sure if its my data controller or what? But it only had that issue when I installed the data controller. I have tried to reset it. Still does the same thing. I'm thinking about doing a hard reset battery and unplugging everything. But not sure why it acts the way it does.

 

The right rear of my car gets to be 1/2" lower than the right. I brought it to Lexus last week and they fixed it "reset it". They said if it sits to long or stays on a lift to long.

It's still doing it, any thoughts? Lexus said they'd look at it again but it's a 2 hour drive for me.
