OK - Day before yesterday i drove my 2007 Lexus GX for an oil change (love this car). I got the car back and did not have any issues. Woke up the next day and the rear suspension is visibly lower than the front. I tried to bounce the rear to see if the shocks were spent, but it could not go any lower. Took the car to my mechanic and he hooked up his computer (multiple computers) to the diagnostics - the rear suspension did not register. He was able to talk to the rest of the car but not the rear suspension.
In summary - no problems one day to no rear suspension the next. Air shocks or suspension computer? Thoughts??

If the compressor and height regulation aren't on the CANBUS network, I would look at fuses and wiring first. Then run 12v to the compressor to see if it's still good. And then swap computer modules.
