2012 Toyota Tundra

CHECK ENGINE LIGHT AND TRAC CONTROL LIGHTS CAME ON AROUND 72,000 MILES. TRUCK STARTED TO BE SLUGGISH AND LOSE POWER. THE TRUCK IS IN A CONSTANT 'LIMP' MODE AND FAILS TO PROPERLY ACCELERATE. IT IS DEFINITELY A SAFETY ISSUE AS IT CAUSES UNSAFE CONDITIONS WHEN TRYING TO ACCELERATE INTO A TRAFFIC LANE. TOOK IT TO DEALER AND IT IS AN ISSUE WITH THE SECONDARY AIR INJECTION VALVES AND PUMPS. DEALER QUOTED ME $2184.25 TO FIX. NOT CURRENTLY COVERED UNDER WARRANTY. TOYOTA HAS ADDRESSED THIS ISSUE WITH OTHER YEARS AND MODELS BUT FOR SOME REASON HAS EXCLUDED THE 2012 TUNDRA. I HAVE CONTACTED TOYOTA ON MULTIPLE OCCASIONS AND THEY REFER ME TO NHTSA TO FILE A COMPLAINT. SAME ISSUES REPORTED FOR THE 2012 TOYOTA TUNDRA REFERENCE NHTSA ID NUMBERS: 11129958 11129497 11128204 11109923 11104774 11076034 11075528 11065298 11002406 10994136 10926200 10567001 10489030 HOW MANY COMPLAINTS HAVE TO BE FILED BEFORE TOYOTA CORRECTS THE ISSUE?

CHECK ENGINE LIGHT WITH ERROR CODE P2433 0160-11 FAILURE OF AIR INJECTION PUMPS I WAS GETTING ON THE HIGHWAY, THE ENGINE LIGHT COMES ON, THEN THE TRUCK GOES INTO "LIMP MODE." THE LANE I WAS IN MERGED TO THE LEFT. I NEEDED TO ACCELERATE TO AVOID A VEHICLE COMING UP ON MY LEFT, BUT THERE WAS NO POWER DUE TO BEING IN "LIMP MODE." THE VEHICLE COMING UP BEHIND ME HAD TO SLAM ON HIS BRAKES AND I SWERVED OFF THE SHOULDER. THIS COULD HAVE BEEN A VERY BAD ACCIDENT IF THERE WAS A CONCRETE BARRIER IN FRONT OF ME. THIS IS A KNOWN MALFUNCTION AND SHOULD BE A RECALL ITEM. TOYOTA HAS PUBLICALLY SAID THIS IS A WARRANTABLE REPAIR UP TO 150,000 MILES ON 2011 MODEL YEAR TUNDRAS. I HAVE THE EXACT SAME PROBLEM ON MY 2012 (WHICH WAS BUILT IN 2011) BUT TOYOTA IS NOT WILLING TO COVER THE REPAIR. I WILL NOW BE OUT OF POCKET $3400 IF I WANT TO KEEP DRIVING MY TRUCK.

I SEE SEVERAL OTHER COMPLAINTS HERE WITH MY EXACT PROBLEM. THE SECONDARY AIR INJECTION SYSTEM RELAY AND SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE. OBD II CODES P0418 AND P2442. MY EXPERIENCE IS THE SAME AS OTHER COMPLAINTS IN THAT MY TRUCK IS NOW PERMANENTLY IN LIMP MODE AND CANNOT BE DRIVEN DUE TO THESE KNOWN DEFECTIVE PARTS. ON PRE-2012 MODEL TUNDRAS TOYOTA HAS EXTENDED THE REPAIR WARRANTY TO 10 YEARS/150,000 MILES AS THIS IS A WIDESPREAD PROBLEM. FOR SOME REASON THEY WILL NOT INCLUDE LATER YEAR MODEL TRUCKS LIKE MY 2012 4.6 LITER. THIS IS A SAFETY ISSUE AS THE TRUCK SLOWED SEVERELY IN TRAFFIC AND WILL NOT ACCELERATE OR GO UP ANY HILL. CARS BEHIND ME IN TRAFFIC HAD TO SWERVE AROUND ME. I WAS STUCK DEAD AT THE BOTTOM OF A HILL AS THESE CHRONICALLY FAILING PARTS SHUT DOWN THE VEHICLE'S POWER. TOYOTA CUSTOMER CARE HAS DENIED MY ATTEMPT TO SEEK COMPENSATION OR REPAIR OF THESE PARTS THAT THEY KNOW ARE DEFECTIVE. THE FIX NEEDS TO BE EXTENDED TO ALL YEAR MODEL AND ENGINE SIZE TUNDRAS AS THESE DEFECTIVE PARTS EXIST ON MODELS PAST 2011. A SIDE NOTE, SOMEHOW THESE DEFECTS ARE REPORTED TO BE AFFECTING THE VEHICLE SKID CONTROL AS THAT WARNING LIGHT COMES ON WHEN THESE PARTS FAIL ON MOST OF THE AFFECTED TUNDRAS.

AIR INJECTION RELAY AND PUMP FAILURE. THIS CONDITION EVENTUALLY LEADS TO "LIMP" MODE CAUSING TRAFFIC SAFETY ISSUES. THIS HAS BEEN A MANUFACTURER RECALL/EXTENDED WARRANTY ITEM ON ALL TUNDRA TRUCKS, UP TO AND INCLUDING SOME 2012 MODELS BUT NOT ALL OF THE 2012'S. BY THE NUMBERS OF FAILURES PRESENT, IT'S OBVIOUS THAT WHAT EVER DESIGN CHANGES TOYOTA DID TO SAY THEY FIXED THE ISSUE AND EXCLUDE SOME OF THE 2012'S WERE INSUFFICIENT. THIS RECALL/EXTENDED WARRANTY SHOULD INCLUDE ALL 2012 MODELS. TOYOTA/DEALERS CLAIM THE PUMPS ARE PART OF EMISSIONS SO THEY ARE NOT COVERED UNDER THE MANUFACTURERS WARRANTIES. REPAIR COST WAS QUOTED AT $3800. OTHER FILED COMPLAINTS: NHTSA ID NUMBER: 11075528 NHTSA ID NUMBER: 11002406 NHTSA ID NUMBER: 10994136

IN EVENING HOURS DECEMBER 2017 I STARTED MY TRUCK AND THE TRACTION CONTROL LIGHT, CHECK ENGINE LIGHT, AND FLASHING 4 LOL WAS ON. DROVE HOME AND HAD CORRODIED BATTERY TERMINAL. RESET LOTT AND WENT AWAY. ON FEBRUARY 23TH, 2018 MY WIFE STARTED TRUCK AND ALL THREE LIFTS WERE ON AGAIN. MADE A APPOINTMENT WITH TOYOTA DEALERSHIP AND THEY STATED HAD WEAK AIR INJECTION PUMP AND CLOSED SWITCH VALVE. THEY WROTE CAUSE OF HIGH WATER. DROVE OFF THE LOT AND THE LOGS CAME ON AGAIN. I'VE NOT EVEN OWN D MY TRUCK FOR TWO YEARS AND NEVER HAD IT THROUGH HIGH WATER. TOYOTA TOLD ME IT WAS NOT UNDER WARRANTY FOR THE AIR SYSTEM, BECAUSE MY TRUCK IS A 2012. THE COST TO FIX THIS WAS $3,000 DOLLARS. ON WAY HOME MY TRUCK WAS IN LIMP MODE AND I BARELY WAS ABLE TO MAKE IT UP A HILL. NOW I'M OUT OF A TRUCK FOR WORK AND CAN BARELY DRIVE ACROSS TOWN. THERE IS NUMEROUS REPORTS OF THE AIR INJECTION SYSTEM FAILING AND NO ONE HAS OPENED A INVESTIGATION.

MONDAY, JANUARY 15TH I DROVE AT 65 MPH TO WORK AT AND HOME ON THE FREEWAY WITH NO PROBLEMS. TUESDAY AND WEDNESDAY THE TRUCK WAS STATIONARY DUE TO COLD WEATHER CONDITIONS IN HOUSTON, TEXAS. THURSDAY MORNING THE 18TH, I DROVE AT 65 MPH TO WORK VIA FREEWAY WITH NO PROBLEMS. AFTER LUNCH I DROVE AT 45 MPH BACK TO WORK ON A STREET AND NOTICED THE CHECK ENGINE AND TRACTION LIGHT CAME ON AND SIMULTANEOUSLY THE TRUCK THEN STARTING DRIVING EXTREMELY SLUGGISH AND AND FAR BELOW THE SPEED LIMIT OBSTRUCTING THE FLOW OF TRAFFIC. I CAREFULLY GOT OVER AND DROVE THE TRUCK ONLY ALLOWED AT 30 MPH BACK TO THE OFFICE. AFTER CAREFULLY DRIVING HOME VIA STREET AT THE END OF THE DAY I GOT HOME AND REMOVED THE NEGATIVE WIRE FROM BATTERY AND RE-CONNECTED IT TO SEE IF THIS WOULD RESOLVE THE ISSUE. AFTER DOING SO, THE RESULTS WERE THE LIGHTS IN THE DASH WERE NOW OFF AND THE TRUCK DROVE PROPER WITH NO HINDRANCE. THIS WOULD LAST UNTIL WEDNESDAY 24TH. BOTH LIGHTS CAME BACK ON AND THE TRUCK STARTED AGAIN DRIVING SLUGGISHLY. ITS SEEM THAT WHEN THE LIGHT IS OFF THE TRUCK DRIVES FINE, BUT WHEN IT IS TRIGGERED THE TRUCK IS DRIVES EXTREMELY SLUGGISH. COULD THE BE A DEFECTIVE PART? ANY HELP WOULD BE USEFUL.

I BOUGHT A CERTIFIED USED 2012 PLATINUM TUNDRA WITH 32K MILES AND 2 YEARS LATER WITH REGULAR MAINTENANCE AND A CAM SEAL LEAK FIXED BY THE DEALER, I HAVE FOUND A VERY HARD ROD KNOCK FROM THE ENGINE. I TOOK MY TRUCK BACK TO THE DEALERSHIP TO HAVE THE OIL AND FILTER CHANGED WITH 114.8K MILES ON IT AT THIS TIME AND WAS TOLD I WILL NEED TO REPLACE THE ENGINE. I BELIEVE SOMETHING ISN'T SMELLING RIGHT. DOES ANYONE KNOW ANY ISSUES WITH THE CONNECTION OF THE CAM SEAL LEAK AND THE ROD READY TO BLOW. THE DEALERSHIP SAID IT WOULD BE APPROX. $14K TO REPLACE THE ENGINE WITH 40K MILES ON IT.. REALLY ? AGAIN, I'M SMELLING "NOT MY PROBLEM" FROM THE PEOPLE INVOLVED. WHO CAN I REACH OUT TO ASSIST ME IN RESEARCHING THE CAUSE OF POSSIBLE MIS REPAIR MAINTENANCE ? I APPRECIATE ANYONE'S HELP. BEST REGARDS,

AIR INJECTION RELAY AND PUMP FAILURE. THIS HAS BEEN AN EXTENDED WARRANTY ITEM ON ALL TRUCKS EXCEPT THE MODEL I HAVE WITH THE SAME PARTS AS THE LARGER ENGINE TRUCK. THIS IS A CORPORATE GAME OF NOT ENOUGH COMPLAINTS ON A LESS POPULAR MODEL ENGINE EVEN THOUGH THE PARTS ARE THE SAME AS WHAT IS BEING REPLACED ON SAME YEAR MODELS WITH THE LARGER ENGINE. REPAIR IS ESTIMATED AT $2600

TL* THE CONTACT OWNS A 2012 TOYOTA TUNDRA. WHILE DRIVING APPROXIMATELY 45 MPH, THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHO DIAGNOSED THAT THE AIR INJECTION PUMP AND SWITCHING VALVE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED AND INFORMED THE CONTACT THAT THE VIN WAS NOT INCLUDED IN A MANUFACTURER RECALL. THE APPROXIMATE FAILURE MILEAGE WAS 78,000.

MY 4X4 TOYOTA TUNDRA CREWMAX WITH THE 5.7L ENGINE WAS DIAGNOSED WITH A CAM TOWER LEAK WITH ONLY 15,000 MILES ON IT. FORTUNATELY THE VEHICLE WAS STILL UNDER THE FACTORY POWER TRAIN WARRANTY. TOYOTA MADE THE REPAIR AND PROVIDED A RENTAL CAR FOR ME. I HAVE HEARD THIS IS A COMMON PROBLEM WITH THE 2012-2013 5.7L ENGINE AND I WANT THIS ISSUE TO BE MORE PUBLIC. I WORRY OWNERS OF THIS VEHICLE WILL BE STUCK WITH THE $2,300-$3,000 BILL TO FIX THEIR OWN VEHICLE IF THEIR VEHICLE'S POWER TRAIN WARRANTY HAS EXPIRED. I ALSO WORRY THE ENGINES COULD LEAK OIL ONTO THE EXHAUST MANIFOLD AND CATCH FIRE.
