2007 Toyota 4runner Latches & Locks Problems

THE FIRST OF MY 2007 4RUNNER DOOR LOCK ASSEMBLIES FAILED JUST AFTER THE WARRANTY EXPIRED. FOR THE SECOND ONE, MY DEALERSHIP. THE VEHICLE HAS JUST OVER 80,000 MILES AND THE 3RD OF 4 DOOR LOCKS HAS JUST FAILED AND BEEN REPLACED. I BELIEVE THIS DOOR LOCK ASSEMBLY IS OBVIOUSLY A DESIGN FLAW AND IS NOT AN ITEM I WOULD EXPECT TO FAIL AT ALL OVER THE LIFE OF THE VEHICLE, EVEN ONE, MUCH LESS THREE OUT OF THE FOUR. MY CAR IS GARAGE-KEPT AND DOES NOT EVEN COME CLOSE TO RECEIVING ABNORMAL USE. *TR

1-THIRD ROW SEAT SLAMMED DOWN DURING RELEASE FROM HOOK AND BROKE UNDERSEAT COVER 2-IT HAPPENED ONCE AND COULD HAPPEN IF SOMEONE UNFAMILIAR WITH SEAT TRIES TO LOWER THE THIRD ROW TO SEATING POSITION. UPON RELEASE FROM THE OVERHEAD HOOK, THE SEAT, DUE TO ITS OWN UNSUPPORTED WEIGHT, COULD PIVOT FREELY AND FALL ON THE OPERATOR'S HAND OR ARM, CAUSING INJURY. 3-THE BROKEN PART WAS REPLACED BY DEALER UNDER "GOODWILL". THE BROKEN PIECE OF THE UNDER SEAT COVER IS AVAILABLE. *TR
