NHTSA Complaint #10278452 — 2000 MERCURY MOUNTAINEER

NO SINGLE EVENT LED TO THE FAILURE. THIS APPEARS TO BE A STRUCTURAL DEFECT IN THE REAR LIFT DOOR OF THE MERCURY MOUNTAINEER. THE MOUNTING PLATES FOR THE REAR DOOR HINGES HAVE FAILED. NOTE THAT THE HINGES HAVE NOT FAILED. THE FAILURE IS IN THE MOUNTING POINT IN THE DOOR. ONE SIDE HAS COMPLETELY CRACKED THROUGH AND THE OTHER SIDE HAS PARTIALLY CRACKED. THE CONSEQUENCES ARE THAT IF BOTH MOUNT POINTS FAIL THERE WILL NOT BE ANY THING HOLDING THE TOP OF THE REAR LIFT DOOR. THE DOOR COULD THEREFORE SEPARATE FROM THE CAR AND FALL OFF THE VEHICLE. IF THE MOUNT POINTS FAIL, THE ONLY ITEMS HOLDING THE DOOR WOULD BE THE SIDE LIFT CYLINDERS. THESE CYLINDERS WOULD NOT BE STRONG ENOUGH TO KEEP THE DOOR ATTACHED TO THE VEHICLE. THE FAILURE WAS DISCOVERED 2 DAYS AGO. ACTIONS TAKEN SO FAR ARE LIMITED TO GETTING ESTIMATES TO FIX PROBLEM. MERCURY DEALER REPRESENTATIVE WAS NOT HELPFUL SINCE VEHICLE IS A 2000 MOUNTAINEER AND NOT UNDER ANY WARRANTY. HIS RESPONSE WAS LIMITED TO SAYING HE HAD NEVER SEEN THE PROBLEM BEFORE AND GIVING ME THE NAME OF A COLLISION REPAIR SHOP. HOWEVER, I BELIEVE THIS IS A MAJOR STRUCTURAL FAILURE AND A SEVERE SAFETY ISSUE SINCE IF THE HINGE MOUNTS FAIL COMPLETELY AND THE DOOR FALLS OFF THE VEHICLE WHEN ON THE HIGHWAY, A MAJOR ACCIDENT MIGHT RESULT. *TR
