Hi im kevin can i ask a few questions first then il try to assist .so is suspension going down when car not running? So when you return to car its lowered ?
Ok it certainly sounds like you have a leak the most common place is the rear air suspension bags leaking .there arent any recalls but they are a common fauliure. If you raise vehicle up then spray bags with soapy water .normally you will be able to see bubbles from the leaking area to confirm leak.other than this the car would need to be plugged into diagnostic machine to read fault codes and check pressures in system
