MY VEHICLE HAS HAD THE AIR SUSPENSION FAIL 3 TIMES AND BEEN REPLACED ALONG WITH THE PUMP ACCORDING TO A SAFETY BULLETIN. IT HAS JUST FAILED AGAIN AND IS GOING INTO THE SHOP AGAIN NOW WITH NO WARRANTY. THE AIR SHOCKS WERE JUST REPLACED IN NOV 2010 AND 10,000 MILES LATER THEY AGAIN ARE LEAKING AND FAILING. THIS APPEARS TO BE WIDESPREAD AND THEY ALSO HAVE ISSUED SERVICE BULLETINS AROUND THE FAILURE OF THIS SUSPENSION. - PLEASE NOTE YOUR DROP DOWN FOR VEHICLE TYPE DOES NOT ALLOW THE CORRECT CHOICE VEHICLE OF GL450. *TR
