NHTSA Complaint #10950337 — 2011 TOYOTA RAV4

AT APPROXIMATELY 67,000 MILES (OR LIKELY MUCH SOONER), THIS 4WD VEHICLE EXPERIENCED A LEAKING SEAL IN THE LEFT REAR DIFFERENTIAL/AXLE. THE LEAK WAS DISCOVERED BY THE DEALER DURING A RECENT VISIT TO HANDLE SEVERAL OUTSTANDING RECALL ISSUES. FROM DOING EXTENSIVE ONLINE RESEARCH, THIS APPEARS TO BE A WIDESPREAD AND COMMON PROBLEM WITH THE 4WD RAV4S. IT IS A VERY COSTLY REPAIR (AS MUCH AS $800 AT THE LOCAL TOYOTA DEALER), SO I RESPECTFULLY REQUEST THAT THE NTSB INVESTIGATE THE RAV4 REAR DIFFERENTIAL SEAL LEAKS FOR A POSSIBLE RECALL OR TECHNICAL SERVICE BULLETIN. PLEASE NOTE THAT TOYOTA ALREADY ISSUED A WARRANTY ENHANCEMENT NOTIFICATION (Z4F) WHICH EXTENDS THE NEW VEHICLE LIMITED POWERTRAIN WARRANTY FOR A REAR DIFFERENTIAL COUPLING ISSUE. I BELIEVE THAT THIS WARRANTY ENHANCEMENT SHOULD EXTEND TO THE REAR AXLE SEALS AS WELL. FAILURE OF THE REAR SEAL(S) CAN OF COURSE LEAD TO TOTAL FAILURE OF THE POWERTRAIN AND CAUSE SERIOUS INJURY OR DEATH. I HAVE ATTACHED A PHOTO SHOWING THE LEAKING LEFT REAR AXLE SEAL.
