I should have seen the writing on the wall. I bought a new 2012 Overland 5.7L which now has 21000 miles on it and luckily it is still under warranty. After reading about problems with the Quadra Lift system on this forum, and others, I thought it wouldn't happen to mine. Well it did when suddenly I got the "service air suspension immediately" message. I had used the system often as it was supposedly designed, mainly the park and aero modes. I brought it in to the dealer who changed the control module. I then encountered the same problem a mile down the road along with a "system cooling" warning. I brought it in again and was told that they will consult with Chrysler on a solution. As of now all of the control buttons constantly blink and the suspension is inoperable but the Jeep is still drivable. Will update on the repair progress but I am TOTALLY convinced that ALL QUADRA LIFT SUSPENSIONS WILL EVENTUALLY FAIL. I wish I never went with it. It is beyond me how such an ill designed system is put out on the market. There should be a RECALL
