2012 Toyota Tundra Engine Problems

Your truck suddenly went into limp mode (reduced power mode) while your wife was driving on the highway, with the check engine light turning on. The engine wouldn't accelerate properly and then shut off completely, requiring a tow. This is the third time this has happened.

While plowing your driveway, your engine suddenly lost power and you noticed a burning smell, but no warning lights appeared. When the dealer inspected it, they found oil was leaking through a small crack in the camshaft on the right side of the engine onto the hot exhaust manifold, which burned the engine wiring harness. The dealer recommended replacing the entire engine and transfer case to fix the problem.

Your truck's secondary air injection system failed, causing all dashboard warning lights to turn on and limiting your engine to a very slow speed (25-30 mph), leaving you stranded over 40 miles from home and requiring a tow to the dealer. The repair cost over $3,000, and your dealer indicated this is a common problem on 2012 Tundra V8 models. Toyota has acknowledged this is a known issue on some Tundra V8s but has refused to cover the repair or issue a recall for your model year.

Your check engine light came on and stayed on while driving. A mechanic diagnosed the problem as failed secondary air injectors that need to be replaced. Toyota had offered an extended warranty program (ZG6) to cover this specific failure, but it had already expired by the time you discovered the problem at 98,000 miles. Replacing the air injectors and air switching valves should resolve the check engine light.

Secondary air injection system failed June 2018. Vehicle went into limp mode on highway, a dangerous situation as you go from 70 to 30 MPH rather suddenly. Alamo Toyota dealership in San Antonio stated code PO418 and needs to have air pumps and valves replaced. Cost estimate of $3362.57. Toyota has acknowledged this is a design problem on certain Toyota Tundras but fails to recognize this is an issue on the 2012 4.6L V8 models. Toyota needs to take responsibility that this is still an issue with the 2012 4.6L V8 models.

Check engine light which when checked revealed Air pump and air control valve failures. This is a known problem with 2006-2011 Tundras that Toyota issued an extended warranty for 10 years or 150,000 to replace these parts. There was additional extended warranty for 2012 with 5.7 Liter engine but not the 4.6 liter engine. Safety issue is when total failure occurs vehicle goes into limp mode with max speed of 25MPH which would be bad at highway speeds. Code was run by repair facility and copy is enclosed. Email was sent to Toyota corporate and upon phone call follow up, Toyota refused to do anything towards the defect.

2012 Toyota Tundra Cam Carrier seal/cam tower leak on Passenger side. THE CONSUMER STATED ONCE THE OIL PRESSURE BECOMES HIGHER THAN THE BOND HOLDING THE SEAL ELEMENT, IT BEGINS TO LEAK. THE MANUFACTURER WAS NOTIFIED, BUT DID NOT OFFER ANY ASSISTANCE.

The contact owns a 2012 Toyota Tundra. The contact stated while driving 25 mph, he heard an abnormal sound, and the check engine warning light illuminated. The contact drove to his residence. The contact took the vehicle to the local dealer, where it was diagnosed with needing the secondary air injection system to be replaced. The vehicle was not repaired. The manufacturer had been informed of the failure. The failure mileage was 95,899.

MY TUNDRA WITH 75,000 MILES HAS A CAMSHAFT TOWER LEAK AND THIS OIL IS FALLING INTO THE EXHAUST MANIFOLD WITHOUT BEING NOTICED BECAUSE IT DOESN'T MAKE IT TO THE FLOOR, BUT IT GETS TO THE SENSORS AND STARTS RUINING THEM. TOYOTA MOTOR CO KNOWS ABOUT THIS ISSUE IN ALL THEIR 5.7L ENGINES AND THAT ITS A FACTORY ROBOT ERROR BY NOT APPLYING ENOUGH SEALANT IN THE GASKET. AND THIS IS JUST BEING FIXED IF YOU ARE EITHER UNDER FACTORY WARRANTY OR EXTENDED WARRANTY. THE VEHICLES LOOSE POWER AND IF DRIVING ON A HIGHWAY CAN CAUSE A MAJOR ACCIDENT. THE LEAST THIS COMPANY CAN DO IS OFFER A VOLUNTARY RECALL BUT THEY ARE REFUSING TO DO SO BECAUSE THE FIX WILL COST THEM $3500-$4000 FROM ALL THEIR 5.7L ENGINES ASSEMBLED IN THE U.S. SO FOR MY SAFETY AND THE SAFETY OF MANY TOYOTA DRIVERS AND GENERAL HIGHWAY DRIVERS SAFETY, I HOPE THIS WOULD BE TAKEN INTO CONSIDERATION. THANK YOU

'12 TOYOTA TUNDRA APPEARS TO GO INTO LIMP MODE, BROUGHT IT TO THE DEALER SHIP, A RECALL WAS LISTED FOR SOMETHING, DIDN'T FIX THE ISSUE. HAD TO HAVE ABOUT $1,500OF WORK DONE. FIXED THE ISSUE....FOR 1.5 MONTHS. BACK AT THE DEALERSHIP AGAIN, THROWING ALL THE SAME CODES FOR ALL THE SAME PARTS. CLEARLY THE PARTS BEING USED AREN'T A FIX TO THE PROBLEM, AND SEEMS LIKE MORE THAN JUST IS ARE HAVING THE SAME ISSUE. AT THIS POINT IT'S PLAYING WITH PEOPLES LIVES. TOYOTA DEALT WITH THIS WITH EARLIER MODELS BUT ANYTHING 2012 AND UP , NOTHING IS BEING DONE. SOMEONE IS GOING TO GET KILLED IF THESE TRUCKS GO INTO LIMP MODE ON A HIGHWAY AND THEY GET HIT AT 70-80 MILES AN HOUR FROM SOMETHING OUT OF THE DRIVERS CONTROL, THAT TOYOTA KNOWS ABOUT. WHEN WILL A RECALL CONDO THIS, SOMETHING NEEDS TO BE DONE.

AFTER FILLING UP WITH GAS AND PULLING ONTO HIGHWAY THERE WAS NO POWER LIKE TRUCK WAS IN LIMP MODE AND TRACTOR TRAILOR HAD TO SWERVE OFF OF ROAD TO PREVENT SEVERE ACCIDENT. THE SECONDARY AIR INJECTION HAS A SEVERE MAL FUNCTION WHICH TOYOTA ONLY RECOGNIZED IN EARLIER MODELS AND THEY EXTENDED WARRANTY TO 10 YEAR AND 150,000 MILES. THIS IS A SEVERE PROBLEM I WISH SOMEONE WOULD INVESTIGATE BEFORE IT'S TOO LATE AND LIVES ARE LOST. THERE IS NOT MUCH RESPONSE TIME TO MAKE A QUICK DECISION DURING THIS MOMENT. THANK YOU

LEAKY TUNDRA CAM TOWER SEAL. TOYOTA CLAIMS THAT THEY USES A EPOXY TYPE SEAL THAT HAS BEEN FOUND TO LEAK, AND NEEDED TO BE REPLACED WITH DIFFERENT TYPE OF GASKET SEAL..THE CHARGE FOR THIS APPROXIMATELY $ 5000.00 THAT THEY SAY IS THE CONSUMERS RESPONSIBILITY.

MY 2012 TUNDRA WITH 107K DISPLAYED THE CHECK ENGINE, 4LO, AND TRACTION CONTROL WARNING LIGHTS AND WOULD ONLY DRIVE IN 'LIMP MODE'. LUCKILY THIS HAPPENED AT STARTUP WHEN I WAS LEAVING WORK ONE AFTERNOON, AND NOT AS I WAS DRIVING AT HIGHWAY SPEED. I 'LIMPED' TO THE LOCAL DEALER USING BACK ROADS AND LEFT THE TRUCK FOR DIAGNOSIS. I WAS NOTIFIED THAT THE TRUCK WAS EXHIBITING CODE 'P2440' FOR A FAULTY SECONDARY AIR INJECTION SYSTEM VALVE, AND THAT BOTH SECONDARY AIR PUMPS AND VALVES WOULD NEED TO BE REPLACED TO CORRECT THE ISSUE. THE REPAIR WOULD COST $2500, BUT "LUCKILY" THE DEALER HAD THE PARTS IN STOCK BECAUSE THIS WAS A COMMON PROBLEM. SINCE I NEEDED THE TRUCK TO GET BACK AND FORTH TO WORK EACH DAY, AND I AM NOT READY TO REPLACE IT, I AUTHORIZED THE REPAIR AND PICKED IT UP THE NEXT DAY. SUBSEQUENT RESEARCH ON-LINE SHOWED THAT THIS HAS BEEN A KNOWN ISSUE FOR YEARS. TOYOTA EXTENDED THE WARRANTY ON THESE PARTS FOR MY 2007-2011, AND LATER FOR CERTAIN 2012 VEHICLES AS WELL. UNFORTUNATELY, IT APPEARS THAT ONLY THE 2012S WITH THE 5.7L ENGINE ARE COVERED (MINE IS A 4.6L). FROM MY RESEARCH, IT SEEMS THAT THE PUMPS/VALVES IN MY TRUCK ARE THE EXACT SAME PARTS THAT ARE KNOWN TO FAIL (AND ARE COVERED) IN OTHER MODEL YEARS. I CALLED TOYOTA CUSTOMER SERVICE, AND OF COURSE THEY ADVISED THAT THEY WOULD 'LOG' THE ISSUE AND CONTACT ME SHOULD THE WARRANTY BE EXTENDED TO COVER MY TRUCK. JUDGING BY THE NUMBER OF COMPLAINTS HERE, I FEEL THAT IT WARRANTS AN INVESTIGATION AND PERHAPS APPLYING SOME 'EXTERNAL' PRESSURE TO PERSUADE TOYOTA TO DO THE RIGHT THING AND COVER ALL OF THE AFFECTED VEHICLES. NOT ONLY IS THIS AN EMISSIONS ISSUE, BUT COULD BE A SERIOUS SAFETY ISSUE IF THE TRUCK WERE TO GO INTO LIMP MODE WHILE DRIVING. *TR

I HAVE NOTICED AN OIL LEAK FROM THE CAMSHAFT HOUSING ON MY PASSENGER SIDE. THIS HAS LED TO OIL BURNING ON MY EXHAUST MANIFOLD WHICH IS A FIRE HAZARD.

WITH ONLY 81,719 MILES ON MY TRUCK I HAD TO HAVE THE AIR INJECTION PUMP & VALVES REPLACED ON 3/29/2019. I WAS INFORMED THAT THIS WAS A COMMON PROBLEM WHICH HAD BEEN RECALLED IN THE 2011 & 2010 MODELS. IF A RECALL IS MADE WITHIN A YEAR OF THE PART BEING REPLACED I WILL BE REIMBURSED. I WORK FROM HOME AND THE TRUCK HAS ONLY BEEN DRIVEN FOR LEISURE OR CHORES FOR THE PAST 3 YEARS. IT WAS DRIVEN DAILY IN LAS VEGAS FROM 2015-2017 AND IN ORLANDO FROM 2012-2015. THERE HAVE BEEN NO OTHER ENGINE PROBLEMS. IN JANUARY OF 2019 THE CHECK ENGINE LIGHT CAME ON AND THE CAR WAS PERFORMING WITH LESS POWER BUT EVERYTHING WORKED OKAY. INSTEAD OF DRIVING AN 8 CYLINDER TRUCK IT FELT LIKE DRIVING A FULL SIZE TRUCK WITH ONLY 4 CYLINDERS. THE ISSUE HAPPENED OVERNIGHT. EVERYTHING WAS FINE AND THEN THE PERFORMANCE JUST WENT SOUTH. I WAITED 2 MONTHS TO HAVE IT LOOKED AT BECAUSE I RARELY DRIVE AND BECAUSE IT STILL RAN BUT WITH LESS POWER. I WAS TOLD BY TOYOTA THAT IF ANOTHER MECHANIC FIXED THE PROBLEM AND A RECALL CAME LATER THEN I WOULD NOT BE REIMBURSED. AFTER I WAS INFORMED THAT THIS WOULD MORE THAN LIKELY BECOME A RECALL I MOVED FORWARD WITH USING TOYOTA'S SERVICE DEPARTMENT. MY GOAL IS TO FIND OUT IF THERE IS A RECALL PENDING FOR THE 2012 TUNDRA AIR INJECTION SYSTEM OR AT LEAST FIND OUT IF THE PROBLEM IS WIDESPREAD. IF I WAS TAKEN ADVANTAGE OF BY A DEALERSHIP USING THE RECALL AS A TACTIC TO GET MY BUSINESS I WANT TO MAKE SURE TO LET OTHERS KNOW SO I HOPE SOMEONE FROM THE NHTSA WILL FOLLOW UP. THANK YOU, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

I TOOK MY TUNDRA IN FOR A OIL CHANGE AND THE DEALER SHIP SAID I HAVE OIL LEAK AT THE TIMING BELT. IT WOULD BE OVER 1600.00 TO FIX THIS. IT IS TIME CONSUMING FOR THE LABOR RATE IS HIGH. THE TRUCK ONLY HAS 45,000 MILES ON IT.

MY TRUCK HAS BEEN HAVING HARD START ISSUES SINCE WINTER 2017. I FIGURED IT WAS MY BATTERY SO I REPLACED IT, BUT IT DIDNT HELP. THE HARD START WASN'T CONSISTENT SO I CHOSE TAKE SOME TIME TO SEE IF ANY OTHER PROBLEMS SURFACED. GOT THROUGH WINTER 2018 AND SPRING/SUMMER 2019 WITH IT STILL STARTING ROUGH ON OCCASION. BY OCTOBER 2019 MY TRUCK REACHED APPROX 78K MILES, AND ONE DAY IT DIDN'T START AT ALL. TOOK THREE TRIES TO GET IT GOING. I HAD THE BATTERY CHECKED ONCE AGAIN. IT TESTED BAD BUT IT WAS UNDER WARRANTY SO I HAD I LT SWAPPED OUT. THE PROBLEM PERSISTED. THIS TIME IT GAVE ME AN ENGINE LIGHT. MECHANIC SAID IT WAS AN 'EVAP CODE' AND RECOMMENDED I REPLACE THE GAS CAP TO START. CODE DIDNT RETURN BUT STILL HARD STARTING. TOOK ALMOST TWO MONTHS AND ENGINE LIGHT CAME BACK ON. THIS TIME P1604 STARTABILITY MALFUNCTION. WAS TOLD I HAD TO TAKE IT TO TOYOTA TO GET A REFLASH. I DECIDED TO DO SOME RESEARCH AND CAME ACROSS THE PROBLEMS TUNDRA OWNERS WERE HAVING WITH THIS FFV DENSITY SENSOR MALFUNCTION. PRINTED THE OLD SERVICE BULLETINS AND WENT TO TOYOTA TO TALK TO SERVICE DEPT ABOUT IT. THEY SAID TOYOTA JUST PUT OUT A NEW SERVICE BULLETIN IN DECEMBER 2019 FOR THE REFLASH BUT NOW ALSO REPLACING THE FUEL PUMP (TOYOTA TOLD ME DENSITY SENSOR ATTACHED TO THE PUMP). UNFORTUNATELY TOYOTA ALSO TOLD ME THEY WON'T COVER THE COST SINCE MY TRUCK HAD JUST GONE OVER 80K MILES, AND THEY ARE NOT FLEXIBLE WITH THAT AT ALL, EVEN THOUGH I TOLD THEM IT STARTED BEFORE 80K. T-SB-0166-19. SO I GOT PRICES. THE REFLASH IS ABOUT $140 AND JUST THE COST OF THE PUMP ITSELF IS $600, NOT INCLUDING LABOR. I HAVE SPOKEN TO THE TOYOTA USA CUSTOMER CARE TEAM AND THEY SAID THEY CANT HELP ME SINCE I DIDNT TAKE IT TO THE DEALER TO DIAGNOSE IT. APPARENTLY IT DOESNT MATTER IF YOU HAVE SERVICE RECORDS FROM ANOTHER SHOP. THIS IS MY 3RD TOYOTA, AND I LOVE MY TRUCK SO THIS BREAKS MY HEART.

WHEN DRIVING MY CHECK ENGINE AND "TRAC OFF" LIGHT COMES ON AND THE ENGINEER WILL NOT ACCELERATE ABOVE THIRTY MILES AN HOURS. IF YOU DISCONNECT THE BATTERY AND RESET THE COMPUTER IT WILL WORK FOR ABOUT THREE MILE THEN THE CHECK ENGINE AND "TRAC OFF" LIGHT COMES ON. THIS IS THE SAME INDICATION EARLIER TUNDRA MODELS HAVE WITH SECONDARY AIR INJECTORS RECALL. AN IT IS WIDELY DOCUMENTED ONLINE AS A PROBLEM FOR 2012 TUNDRA'S. YET TOYOTA CONTINUES TO DENIES IT'S A PROBLEM AND IS NOT COVERED UNDER THE RECALL.

DRIVING IN HIGHWAY TRAFFIC AND ENGINE REDUCES POWER SIGNIFICANTLY CAUSING THE VEHICLE TO RAPIDLY SLOW DOWN AND BECOME A HAZARD IN TRAFFIC. TOOK IT TO DEALERSHIP AND THEY SAID THE SECONDARY AIR INJECTION SYSTEM NEEDS TO BE REPLACED FOR $3300. THIS IS A KNOWN DEFECT FOR THE PREVIOUS MODEL YEAR. I CONTACTED TOYOTA HQ AND THEY REFUSED TO COVER REPAIRS FOR THIS KNOW DESIGN DEFECT.

* ONGOING MANUFACTURE DEFECT / SAFETY CONCERN WITH 2012 TOYOTA TUNDRA 4.6. CODE P2440, SECONDARY AIR INJECTION. BANK ONE OPEN.---CHECK ENGINE / TRAC OFF LIGHTS / ENGINE IN "LIMP MODE" * DOCUMENTED RECURRING INCIDENTS ON 4-2-19 AND AGAIN ON 10-12-19 AFTER COSTLY OUT OF POCKET REPAIR. * MY 2012 TOYOTA TUNDRA 4.6 MOTOR DOUBLE CAB HAS EXPERIENCED THE AIR INJECTION PUMP FAILURE TWICE IN A SIX MONTH PERIOD. THIS FAILURE IS A SAFETY HAZARD LEADING TO LOSS OF POWER AND VEHICLE CONTROL. THE FIRST OCCURRENCE WAS AFTER A 2,000 MILE TRIP. DRIVING DOWNHILL THE DASH LIGHTS (CHECK ENGINE / TRAC OFF) CAME AT HIGHWAY SPEED AND IMMEDIATELY VEHICLE POWER REDUCED AS WE TRIED TO POWER UP THE NEXT HILL. WE WERE ABLE TO AVOID BEING RUN OVER BY FOLLOWING VEHICLES BY PULLING OFF THE ROAD, AND LIMPED TO THE NEAREST MECHANIC SHOP. CONTACTED 3 DEALERS AND TOYOTA CORPORATE WITH NO POSITIVE OUTCOME. ALL PARTIES ACKNOWLEDGE THE ONGOING DEFECT BUT WILL NOT PAY OR OFFER A SOLUTION TO END THE PROBLEM. PAID OUT OF POCKET FOR EXPENSIVE REPAIR. THE 2ND OCCURRENCE SIX MONTHS LATER FOUND US AGAIN UNABLE TO REACH OR MAINTAIN SAFE HIGHWAY SPEEDS. AVOID DANGEROUS HIGHWAY SITUATIONS, OR ABILITY TO CLIMB HILLS. BOTH INSTANCES OCCURRED WITHOUT WARNING. * THIS EMISSION CONTROL DEFECT THAT TOYOTA HAS KNOWN ABOUT SINCE THE 2007 MODELS. THEY EVEN EXTENDED THE WARRANTY THROUGH THE 2011 MODEL YEAR. TOYOTA ALSO CLAIMS THE PROBLEM IS NEITHER DRIVE-TRAIN NOR EMISSIONS RELATED. AFTER MANY ATTEMPTS AT THE DEALER AND CORPORATE LEVEL, TOYOTA REFUSES TO EXTEND REPAIRS FOR THIS WELL DOCUMENTED DEFECT BEYOND THE 2011 MODEL. TOYOTA SUGGESTS THAT WHEN ENOUGH COMPLAINTS ARE RECORDED, THEY WILL EXTEND THE WARRANTY ON NEWER MODELS. THE LACK OF SUPPORT FROM DEALERS AND CORPORATE TOYOTA IS ALARMING. THE REPAIR OUT OF POCKET IS EXPENSIVE (FROM $500 FOR A TEMPORARY REPAIR TO $4000 FOR A REPLACEMENT FROM THE DEALER.)

THIS COMPLAINT IS THE SAME AS MANY I SEE HERE AND ACROSS THE INTERNET. DRIVING ON THE WASHINGTON DC BELTWAY AND MY 2012 TUNDRA GOES INTO LIMP MODE WHICH REDUCED MY POWER SIGNIFICANTLY CAUSING A UNSAFE SITUATION TO SAY THE LEAST.. DEALER SAID PROBLEM WAS WITH SECONDARY AIR INJECTION SYSTEM AND THE REPAIR WAS VERY EXPENSIVE. NOW 12 MONTHS LATER THE TRUCK IS HAVING THE SAME PROBLEMS. THIS IS AN INFERIOR SYSTEM THAT TOYOTA SHOULD STAND BEHIND AND COVER ALL THE COSTS ASSOCIATED WITH FIXING INSTEAD OF CHARGING TUNDRA OWNERS AFTER THEY'VE ALREADY SPENT HARD EARNED MONEY ON THE VEHICLE PURCHASE. THIS IS A WIDE SPREAD PROBLEM THAT TOYOTA IS NOT OWNING UP TO.

P0418 SECONDARY AIR INJECTOR RELAY A MALFUNCTION. CHECK ENGINE LIGHT IS ON

I WAS PULLING OUT OF WORK. YOU MUST CROSS 3 LANES OF TRAFFIC PLUS THE CENTER MEDIAN TO TURN LEFT. THIS IS A CITY STREET. SPEED LIMIT IS 45 I BELIEVE WITH MANY VEHICLES GOING FASTER. VEHICLE HAD THE SMOG AIR INJECTION PUMPS AND VALVES FAIL. THIS CUTS POWER DRASTICALLY TO THE ENGINE AND PUTS IT INTO LIMP MODE. I WAS FORCED TO SWERVE BACK INTO AND STAY IN THE CENTER MEDIAN INSTEAD OF MERGE INTO TRAFFIC AS THE VEHICLE HAD LITTLE POWER. I WAS ABLE TO WAIT FOR A BIGGER GAP IN TRAFFIC AND LIMP THE VEHICLE TO THE REPAIR SHOP. I BELIEVE THIS COULD BE DEADLY SHOULD IT OCCUR IF TRYING TO GET ON THE FREEWAY OR PULLING A TRAILER AND THE ENGINE CUTS POWER DRASTICALLY. TOYOTA HAS A LONG HISTORY OF ISSUES WITH THESE PARTS FAILING GOING BACK TO 2007 AND POSSIBLY EARLIER. THERE IS NO NEED FOR A SMOG PUMP FAILURE THAT ONLY RUNS FOR 2 MINUTES ON COLD START TO DRASICALLY CUT ENGINE POWER AND ENDANGER THE DRIVER AND OTHER MOTORISTS.

WHILE DRIVING, MULTIPLE DASHBOARD LIGHTS CAME ON AND MY TRUCK WENT INTO "LIMP MODE," MEANING I LOST ALMOST ALL POWER WHILE DRIVING IN HEAVY TRAFFIC. TURNS OUT THIS IS AN ISSUE WITH THE AIR INJECTION PUMP, WHICH IS A KNOWN PROBLEM IN TOYOTA TUNDRAS. I BELIEVE THIS IS A SAFETY ISSUE THAT TOYOTA NEEDS TO ADDRESS.

I OWN A 2012 TUNDRA WITH THE 4.6 LITER V8 ENGINE. VERY VERY SIMILAR OR EXACT TO OTHER COMPLAINTS ON THIS BOARD. TRUCK WENT INTO LIMP MODE WHILE ON THE HIGHWAY. TOOK THE VEHICLE TO THE DEALERSHIP AND HAD TO PAY TO HAVE THEM REPLACE THE SECONDARY AIR INJECTION PUMPS AND VALVES. I AGREE THE FIX NEEDS TO BE EXTENDED TO ALL YEAR MODELS AND ENGINE SIZE TUNDRAS, NOT JUST UP TO 2011. ALSO AGREE THAT THESE DEFECTS COULD RESULT IN A FATAL SITUATION IF NOT CORRECTED ACROSS THE BOARD. TOYOTA SHOULD ALSO REIMBURSE THOSE THAT HAVE HAD TO PAY FOR THE REPAIR.

I HAVE A 2012 TUNDRA WITH 135K AND 4.6 LITER. I ALSO SEE SEVERAL OTHER COMPLAINTS HERE WITH MY SAME PROBLEM. MY EXPERIENCE IS THAT AFTER SUDDEN JUMP IN MY RPMS FROM 2 TO 4 AND ACCELERATOR MALFUNCTIONING, I CAREFULLY AND VERY SLOWLY DROVE MY TRUCK TO THE DEALERSHIP THIS MORNING DUE. I HAD SLOW/NO ACCELERATION, CHECK ENGINE LIGHT ON AND TRACTION OFF. IN LAST COUPLE OF MONTHS, HAVE HAD TO PULL OVER TURN IT OFF AND BACK ON FOR IT TO GO AGAIN ONCE BEFORE. I AGREE THAT THE FIX NEEDS TO BE EXTENDED TO ALL YEAR MODELS AND ENGINE SIZE TUNDRAS, NOT JUST UP TO 2011. ALSO AGREE THAT THESE DEFECTS COULD RESULT IN A FATAL SITUATION IF NOT CORRECTED ACROSS THE BOARD.

TRUCK WENT INTO LIMP MODE BECAUSE OF SECONDARY AIR INJECTION VALVE AND AIR PUMP DUE TO STUCK VALVE. THE EXACT SAME PARTS THAT TOYOTA HAS EXTENDED THE WARRANTY ON FOR 2007 THRU 2011 4.6 AND 5.7 V-8'S. DO THEY WAIT ON THE. 2012 MODELS SO MOST WILL GO PAST THE 150,000 MILE EXTENSION. VERY DISAPPOINTED SINCE I BOUGHT THIS TRUCK 3 MONTHS AGO. AND NOW THEY WANT $2800 FOR A 4 HOUR JOB AND ABOUT $600 IN PARTS

TL* THE CONTACT OWNS A 2012 TOYOTA TUNDRA. WHILE MERGING INTO TRAFFIC AT A LOW SPEED, THE VEHICLE WENT INTO LIMP MODE AND HAD TO BE TURNED OFF AND RESTARTED. THE FAILURE OCCURRED MULTIPLE TIMES. THE VEHICLE WAS TAKEN TO GERMAIN TOYOTA OF NAPLES (13315 TAMIAMI TRAIL N, NAPLES, FL 34110, (888) 722-4942) WHERE IT WAS DIAGNOSED THAT THE AIR PUMP ASSEMBLY AND VALVE SHAFT NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 119,000.

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.

TL* THE CONTACT OWNS A 2012 TOYOTA TUNDRA. THE CONTACT STATED THAT THE VEHICLE SLOWLY ACCELERATED FROM A STOP SIGN WHEN THE ACCELERATOR PEDAL WAS DEPRESSED. IN ADDITION, THE STABILITY TRACTION CONTROL WARNING INDICATOR ILLUMINATED. THE FAILURE RECURRED ON NUMEROUS OCCASIONS. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC WHERE IT WAS DIAGNOSED THAT THE AIR INJECTION FAILED AND NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED DUE TO THE REPAIR FEES. THE VEHICLE WAS NOT TAKEN TO A DEALER. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND OPENED CASE NUMBER: [XXX].

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.

AFTER STARTING THE ENGINE, THE ENGINE RAISED PAST RED LINE RPM FOR SEVERAL SECONDS. AFTER SLOWING, I STARTED TO BACK OUT DRIVE WHEN ENGINE RAISED AGAIN INTO RED LINE RPM. BEFORE I GOT IT PULLED BACK INTO DRIVE, IT RAISED 3 MORE TIMES. EACH TIME I MANAGED TO GET TO NEUTRAL.

AFTER ONLY A FEW MONTHS OF OWNING THE TRUCK ALMOST EVERY MORNING WHEN I TRY TO START THE TRUCK IT TOOK AT LEAST 2 CRANKING CYCLES TO START. IT'S BEEN A ON GOING THING AND NOW THE THROTTLE ACTS UP WHEN I FIRST PULL OUT OF THE DRIVEWAY. IT DOESN'T GIVE ANY CODE AND THE DEALERSHIP CAN'T FIGURE IT OUT. THE TRUCK NOW HAS 36322 MILES ON IT. *TR

MY ISSUE IS RELATED TO THE ISSUE I AM FACING WITH TOYOTA COMPANY. I PURCHASED MY TRUCK WITHIN 2012 AND SINCE I HAVE PURCHASED THE TRUCK I TOOK THIS TRUCK TO THE DEALERSHIP FOR SEVERAL ISSUES. WITHIN FEW MONTHS OF PURCHASE THE AIR INJECTION PUMP STOP WORKING, TRUCK WAS AT THE DEALERSHIP FOR OVER A MONTH. TOYOTA INSTALLED TRD UPDATED FOR MY "INCONVENIENCE" I TOOK MY TRUCK BACK TO HAVE LOOKED AT OVER 10TIMES. ON FRIDAY I START HAVING THE SAME ISSUES, SO I DROPPED OF MY TRUCK AT THE SZOTT DEALERSHIP ON SATURDAY EVENING MARCH 1ST. MONDAY MORNING SERVICE MANAGER CALLED AND INFORMED THAT AIR INJECTION PUMP IS BAD AND IT MAY TAKE OVER 4 WEEKS TO HAVE THE PART REPLACED, ABOUT 4 WEEKS AGO TRUCK STOP RUNNING SO I TOOK IT TO THE DEALERSHIP CLOSE BY IN CANTON, TOYOTA OF CANTON REPLACE THE FUEL PUMP, TRUCK WAS AT THE DEALERSHIP FOR A WEEK. I TRY REACHING OUT TO TOYOTA AND SEE IF THEY COULD HELP ME RESOLVE THE ISSUE, BUT TOYOTA DON'T CARE. SEE BELOW EMAIL I SENT TO TOYOTA ON 12-13. I WAS ASSIGN "CASE MANAGER" WAS NO HELP AT ALL. ALL I AM ASKING TOYOTA TO REPLACE/RESOLVE MY TRUCK ISSUES. I AM TIRED OF TAKING MY TRUCK FOR REPAIRS. I WILL FILE THE COMPLAINT TO THE ATTORNEY GENERAL'S OFFICE AS WELL. ISSUES WITH CABIN IS BEING LOUD AIR COMES FROM THE WINDSHIELD AND FORM THE LEFT AND RIGHT DOORS/WINDOWS. TRUCK WAS AT THE DEALERSHIP LAST YEAR FOR OVER 3 WEEKS DUE TO THE AIR INTAKE PUMP ISSUE. I AM STILL FACING THE SAME ISSUES WHILE DRIVING TRUCK LOSE POWER AND WHILE I AM PULLING OVER SOME TIME I GET THE POWER BACK SOME TIME I HAVE TO WAIT TO MAKE SURE I CAN DRIVE OVER 25MILES PER HOUR. ALL THE BRAKES HAVE BEEN REPLACED DUE TO VIBRATION, NAVIGATION SYSTEM GOES IN AND OUT WHILE DRIVING, DEALERSHIP WAS INFORMED. WHOLE DASH LIGHTS ELECTRIC IN THE DASH FLICKER WHILE DRIVING. LAST MONTH BATTERY DIED AND ELECTRIC ISSUES ARE STILL THERE. *TR

I PURCHASED MY FLEX FUEL TUNDRA 5.7 IN NOVEMBER OF 2011. I STARTED TO EXPERIENCE ISSUES WITH COLD STARTS IN DECEMBER OF 2012. I HAD AN EXTENDED CRANK TIME, AND IT WOULD TAKE MULTIPLE ATTEMPTS TO START THE TRUCK. I TOOK IT TO THE DEALERSHIP FOR THE FIRST TIME IN JANUARY OF 2013. THE DEALERSHIP RESET MY COMPUTER. THE ISSUE SEEMS TO BE RESOLVED. THE FOLLOWING WINTER, IN DECEMBER OF 2013, I STARTED TO EXPERIENCE THE SAME ISSUE WITH COLD STARTS. THE DEALER APPARENTLY RESET MY COMPUTER AGAIN. JUST A MONTH LATER, JANUARY 2014, THE EXTENDED CRANK ON COLD STARTS BEGAN AGAIN. THIS TIME, THEY TOLD ME MY ALCOHOL DENSITY WAS READING 49%. THEY SAID IT SHOULD BE AT 85%, HOWEVER, I AM NOT USING STRAIGHT ETHANOL GAS, WHICH I TOLD THEM NUMEROUS TIMES, SO MY READING SHOULD NOT BE 85%. I WAS TOLD THE COMPUTER SHOULD RESET TO 0 WHEN I FILL UP, BUT MY TRUCK IS NOT. IT'S JUST BUILDING UP, WHICH RESULTS IN AN INACCURATE ALCOHOL DENSITY READING. THE DEALERSHIP TOLD ME THAT THE ONLY CURRENT SOLUTION IS IF MY TANK DROPS BELOW 1/4 TANK, I SHOULD ONLY FILL IT HALF WAY, DRIVE IT GENTLY, AND THEN GO BACK TO FILL IT THE REST OF THE WAY. AFTER FILLING IT, I WAS TOLD TO LET IT IDLE, AND DRIVE IT GENTLY WHEN I PULL OUT OF THE GAS STATION. THIS IS UNACCEPTABLE. FOLLOWING MY LAST VISIT TO THE DEALERSHIP, WHEN I REFILLED MY TRUCK FOR THE FIRST TIME AFTER THE LAST RESET, THE 'MILES TO EMPTY' WAS READING 425! MY TRUCK USUALLY RANGES BETWEEN 300 AND 320. THE 426 MILES TO EMPTY READING ONLY HAPPENED ONCE, BUT AGAIN, THE INCONSISTENCY AND INACCURATE READINGS ARE NONSENSE, ESPECIALLY ON A $35K+ VEHICLE. SINCE THEN, I HAVE RESEARCHED THE ISSUE, AND I'M NOT THE ONLY TUNDRA OWNER WITH THIS ISSUE. OTHER FLEX FUEL TUNDRA OWNERS ARE HAVING THE SAME ISSUE. *TR

CHECK ENGINE LIGHT ILLUMINATED AS I DEPARTED MY DRIVEWAY. I CALLED TOYOTA SERVICE TO SCHEDULE AN APPOINTMENT WHICH OCCURRED THREE DAYS LATER. TOYOTA SERVICE DEPARTMENT DETERMINED THAT THE AIR PUMP, WHICH IS PART OF THE EMISSIONS SYSTEM, FAILED. I WAS ADVISED THE TRUCK COULD NOT BE DRIVEN. AS OF TODAY (12/17/12) THE PART HAS STILL NOT ARRIVED AT BOCH TOYOTA SOUTH. WILL THE DEFECTIVE AIR PUMP CAUSE PREMATURE FAILURE OF THE CATALYTIC CONVERTER? *TR
