Recall History (9 recalls)
STEERING:LINKAGES:ROD:RELAY:CONNECTING
VEHICLE DESCRIPTION: PASSENGER VEHICLES. THE TIE RODS OF THE STEERING ASSEMBLY ARE PROTECTED ON EACH SIDE BY A SEAL TO PREVENT MOISTURE AND DUST PARTICLES FROM ENTERING THE SWIVEL BEARING MECHANISM. IT IS POSSIBLE THAT SOME TIE ROD SEALS MAY NOT SEAL PROPERLY.
FUEL SYSTEM, GASOLINE:STORAGE:TANK ASSEMBLY
VEHICLE DESCRIPTION: PASSENGER VEHICLES. SULFUR IN FUEL INTERACTS WITH CERTAIN ADDITIVES FOUND IN WIDELY AVAILABLE GASOLINE CAUSING SULFUR TO BECOME DEPOSITED ON THE CONTACT POINTS OF THREE FUEL SENDING UNITS MOUNTED INSIDE THE FUEL TANK. THIS COULD CAUSE THE FUEL GAUGE TO READ FULL WHILE THE FUEL TANK MAY NOT IN FACT BE FULL OR COULD BE EMPTY.
ELECTRICAL SYSTEM
ON CERTAIN PASSENGER VEHICLES, IF A DRIVER'S KNEES PUSH AGAINST THE KNEE BOLSTER (CRASH ELEMENT) LOCATED UNDER THE DASHBOARD, IT CAN CONTACT THE HEADLIGHT SWITCH WIRING HARNESS, AND AN ELECTRICAL SHORT COULD OCCUR.
VEHICLE SPEED CONTROL
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH 2.8L, V6 5-VALVE ENGINES, AND AUTOMATIC TRANSMISSIONS, WHILE DRIVING DURING EXTREMELY LOW AMBIENT TEMPERATURES THE THROTTLE MAY FREEZE IN AN OPEN POSITION DUE TO ICE ACCUMULATING IN THE THROTTLE BODY.
ELECTRICAL SYSTEM
ON CERTAIN PASSENGER VEHICLES EQUIPPED WITH HALOGEN LOW BEAM HEADLIGHTS, CERTAIN CONNECTOR PINS IN THE HEADLIGHT SWITCH CONNECTOR COME INTO CONTACT WITH EACH OTHER CAUSING A SHORT CIRCUIT. NOTE: VEHICLES WITH XENON LOW BEAM HEADLIGHTS ARE NOT AFFECTED BECAUSE THE CIRCUIT IN THESE VEHICLES CONTAINS A FUSE, WHICH PRECLUDES EXCESSIVE CURRENT FLOW IN THE CASE OF A SHORT CIRCUIT. AUDI S6 AND S6 AVANT VEHICLES ARE ALL EQUIPPED WITH XENON LOW BEAM HEADLIGHTS AND, THEREFORE, ARE NOT LONGER AFFECTED BY THIS RECALL.
