NHTSA Complaint #11340221 — 2016 BMW X5

REAR AIR SUSPENSION SYSTEM FAILED COMPLETELY WHILE DRIVING AT LOW SPEED ON A DRIVEWAY, AND WITHOUT WARNING AND WITHOUT ANY IMPACT (COLLISION, BUMP, POTHOLE, ETC). THERE WAS A LOUD BAG AND BOTH COMPRESSION SPRING COMPLETELY DEFLATED, THE CAR ESSENTIALLY DROPPED TO THE AXIL, RESULTING IN EXCESSIVE AND UNCONTROLLABLE BOUNCING. UPON MECHANICAL INSPECTION A FUSE HAD BLOWN BUT ALL COMPONENTS OF THE REAR AIR SUSPENSION SYSTEM WERE INTACT EXCEPT FOR A VERY SMALL PINHOLE LEAK IN THE RIGHT REAR AIR SHOCK. THERE WAS NO WARNING! NO WARNING LIGHTS, INDICATORS OR SENSOR ACTIVATED PRIOR TO THE FAILURE OR FOLLOWING THE FAILURE. I'M CONCERNED THIS IS A SERIOUS SAFETY, DESIGN FLAW IN THE VEHICLE'S REAR SUSPENSION AND SINCE THERE IS NO WARNING, WHATSOEVER, IT COULD HAPPEN ANY TIME, EVEN A HIGHWAY SPEEDS, WHICH I FEAR COULD HAVE RESULTED IN SERIOUS INJURY OR DEATH THE CAR WAS 4 YEAR AND 3 MONTHS AND 54K MILES IN SERVICE.
