got a service suspension system message in my driver info center (DIC), went to dealer and they said the "Level Ride compressor exhaust valve was shorted" (which might also explain the rough ride I now have, I feel like I am driving a 3/4 ton Escalade) and it needed to be replaced, that's the good news. The bad news is that they did not have one, and that they are on "backorder" that sounds scary. Anyone with same issue or been waiting for one??? Or is my situation a rare fluke?
