'TAKATA RECALL' MY AIR SUSPENSION WONT MAINTAIN THE PROPER AIR TO KEEP THE AIR SUSPENSION INITS PROPER PLACEWHEN PARKED. ALSO THE TIRE PRESSURE MONITORS IS VERY ERATIC AND DONT DISPLAY TIRE PRESSURE LIKE ITS SUPPOSE TOO WHILE DRIVNG LOCALLY AND ESPECIALLY ON THE HIGHWAY. THIS CAR ONLY HAVE 65000 MILES ON IT AND I DIDNT EXPECT THESE PROBLEMS FROM A 2011 MERCEDES WITH LOW MILES.
