NHTSA Complaint #11139203 — 2012 TOYOTA TUNDRA

PLEASE REFER TO TSB 0160-11. TOYOTA RECOGNIZED THAT INFERIOR QUALITY PARTS WERE USED AS PART OF THEIR EMISSIONS SYSTEM AND WROTE THIS TSB AS A REMEDY. THE PROBLEM I HAVE IS THAT THEY CONTINUED TO USE THE FAULTY PARTS BEYOND THE 2011 MODEL YEAR CUT-OFF IN THIS TSB. MY TRUCK IS THROWING THE SAME ENGINE AND EMISSIONS CODES ASSOCIATED WITH THIS TSB. IT ALSO FORCES THE ENGINE INTO A "LOW POWER MODE" GREATLY REDUCING THE ABILITY TO ACCELERATE. LASTLY, IT TURNS OFF TRACTION CONTROL WHICH AFFECTS THE STABILITY OF THE TRUCK. I HAVE FILED A TICKET WITH TOYOTA AND FROM WHAT I HAVE READ ON THE INTERNET, I DON'T EXPECT MUCH HELP. THE PARTS TO REPAIR THIS RUN OVER $1,000 ALONE. THERE ARE MANY OWNERS HAVING THE SAME ISSUE WITH THE TUNDRA, SEQUOIA AND SOME OTHER MODELS (ON THE 4.6L, 4.7L AND 5.7L ENGINES). THE ENGINE CODES USUALLY APPEAR ON STARTUP (WHEN THE EMISSIONS DEVICE ARE SUPPOSED TO KICK IN), BUT THE LOW POWER MODE KICKS IN WHILE MOVING.
