NHTSA Complaint #10415809 — 2008 TOYOTA TUNDRA

THE ENGINE CHECK LIGHT CAME ON AND THE ENGINE WENT INTO LIMP MODE, WHICH REDUCES ENGINE POWER MAKING IT DANGEROUS TO DRIVE. THE CHECK ENGINE LIGHT CAME ON FROM THE EMISSIONS VALVE SET FAILING. WHEN REPAIRED BY DEALER THEY ALSO DISCOVERED A CRACKED MANIFOLD. THIS EMISSIONS VALVE SET FAILURE SEEMS TO BE VERY COMMON ON 2008 TUNDRAS AND IS VERY EXPENSIVE TO REPAIR. TO MY SURPRISE THE MANIFOLD WAS CRACKED AND THAT IS A VERY EXPENSIVE REPAIR AND MAY HAVE CONTRIBUTED TO THE EMISSIONS VALVE SET FAILURE. TOYOTA SHOULD RECALL THEIR EMISSIONS VALVE SET AND REDESIGN IT SO IT DOES NOT FAIL, AND IS LESS EXPENSIVE TO REPLACE, AND FINALLY THEY SHOULD NOT PROGRAM THE ENGINE TO GO INTO LIMP MODE IF THIS FAILURE OCCURS, AS IT CAN CAUSE YOU TO LOSE POWER WHILE DRIVING IN VARIOUS CONDITIONS THAT REQUIRE POWER TO GET OFF THE ROAD SAFELY.
