The contact owns a 2012 Toyota Tundra. The contact stated while starting the vehicle, the check engine warning light was illuminated. The contact stated that the light stayed illuminated while driving. The contact had taken the vehicle to an independent certified mechanic where it was diagnosed and determined that the secondary air injectors needed to be replaced. The mechanic informed the contact that the manufacturer had offered an Extended Warranty Program to cover the failure under "Warranty Enhancement Program ZG6" for "Air Injection Pumps and Air Switching Valves" and that the warranty had expired several months prior. The vehicle had not been repaired. The manufacturer had been informed of the failure. The failure mileage was approximately 98,000.

Secondary air injection system failed May 2019. ALL dash warning lights came on. Researched on-line and found truck would not have accelerated past “limp mode” (25-30 mph). Had to have vehicle towed to local Toyota dealer as I was over 40 miles from home (all highway). Toyota dealer diagnosed secondary air injection system failure. Cost to repair OVER $3000. Toyota has acknowledged this is a KNOWN design problem on the Tundra “big” V8s but refuses to recognize this is a design problem on the 2012 4.6L V8 models. Local dealer stated “we have lots of these lying around the shop so no problem getting the part.” Indicating this is a common problem/repair. Spoke directly with Toyota Corporate office who refused to acknowledge design fault or reimburse for repair. This is a HUGE safety issue caused by a known Toyota design problem that needs to be investigated by NHTSA. Toyota MUST be help accountable for this problem and made to correct the problem with a "recall".

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.

FUEL/PROPULSION SYSTEM
13 complaints
The fuel pump failed on my Tundra. Several dashboard check engine lights suddenly lit up to warn me of the issue. While I was able to safely get it to a mechanic to repair the independent Toyota certified mechanic I use shared they have seen a volume of these where the car stops immediately with the Fuel pump failing completely. I was lucky as the day prior to this I was driving through mountain passes on the highway in Colorado. I have since found out from the feedback from my mechanic that they have repaired a volume of these, and it is a known issue by Toyota who issued a technical service bulletin. The fuel pump needs to be replaced with a different specification - the original pump is not sufficient. My concern is putting driver/passenger safety at risk with a complete fuel pump failure while driving. I consider this a near-miss for me, and would worry about others that are about to have this issue.

THE TRAC OFF LIGHT AND CHECK ENGINE LIGHT CANS ON AT THE SAME TIME. I TOOK IT TO TOYOTA AND THEY SAID THERE WAS AN EXTENDED WARRANTY OF 10 YEARS OF 150,000 MILES. IF IT WAS THE SECONDARY VALVES AND AIR PUMPS. I GOT A CALL BACK AND THEY SAID IT WAS, BIG MY VIN WAS NOT PART OF THE EXTENDED WARRANTY. THIS IS AN ISSUES WITH 100S OF TUNDRAS. THIS IS A SAFETY ISSUE. BECAUSE YOU CAN'T GO OVER 60 OR GET TO 60 SAFELY. THE TOYOTA BLOGS ARE FULL OF TUNDRA OWNERS COMPLAINING. THIS NEEDS TO BE FIXED.
Aug 07, 2020
MY 2012 TUNDRA HAD A TRAC OFF AND ENGINE LIGHT COME ON. THIS IS THE SAME PROBLEM FOR NUMEROUS TOYOTA TUNDRA IN REGARDS TO FAILURE OF THE SECONDARY AIR VALVES AND PUMPS. I WAS TOLD MY VIN NUMBER WAS NOT ON THE 10 YEAR , 150,000 MILE WARRANTY FOR THIS SAME PROBLEM. I URGE YOU TO FORCE TOYOTA TO ADD MY VIN NUMBER TO THE EXTENDED WARRANTY. MY VEHICLE CANNOT GO OVER 60 AND BE SAFE. IT WAS RAINING AND RAIN GOT INTO THE PUMP SYSTEM. TOYOTA HAS REPLACED THOUSANDS OF THESE BADLY DESIGNED SYSTEM AND MORE NEEDS TO BE DONE. IT COST OVER $2,000 TO REPLACE BADLY DESIGNED SYSTEM.

2012 TOYOTA TUNDRA 4.6 L AT 101,000 MILES WENT INTO LIMP MODE CAUSING A LACK OF POWER AND ACCELERATION DURING CITY DRIVING WHICH COULD HAVE RESULTED IN A REAR END COLLISION. WAS ABLE TO LIMP VEHICLE TO NEARBY TOYOTA DEALER WHO DIAGNOSED THAT THE SECONDARY AIR INJECTION SYSTEM WAS FAULTY. COST TO REPAIR WAS MORE THAN I WANTED TO PAY BEINGTHAT I HAD JUST PURCHASED THE TRUCK WITHIN THE PAST MONTH OR SO. TOYOTA DID NOT COVER THE REPAIR SO A BYPASS KIT WAS INSTALLED AT MY EXPENSE TO GET THE TRUCK BACK UNDER POWER. CONTACTED TOYOTA AND THEY ADVISED THAT THE SYSTEM WAS NOT COVERED HOWEVER IT SHOULD BE NOTED THAT ON 2010 MODELS AND OTHERS THE WARRANTY ON THE SYSTEM WAS EXTENDED TO 150,000 BUT NOT ON THE 2012 4.6L ENGINES THAT HAVE THE SAME PROBLEMS AS THE OTHERS.

The horn no longer works on the vehicle. I can no longer alert drivers who do not see me while driving or in parking lots. My auto shop confirmed the horn did not work and estimated the repair. There were no warnings.
Dec 16, 2022
The horn can not be operated by the steering wheel. The horn still works when the panic alarm is pressed. According to several forums that I have visited, it’s a common issue with the steering column rubbing the insulation off of the wire. I believe that if this is that common of an issue, it should be reported, and hope that it will be addressed by a recall.

WHEN IN MOTION THE VEHICLE ENTERS LIMP MODE AND LOSES POWER. ACCELERATION BY PEDAL DOES NOT FUNCTION, THE ENGINE ONLY REVS AND DOES NOT SPEED UP. THE VEHICLE SLOWS DOWN TO ANYWHERE FROM 25 TO 5 MILES PER HOUR ON ITS OWN WITHOUT STEPPING ON THE BRAKE AND THE TRANSMISSION DOESN'T SHIFT. THIS HAPPENS ANYWHERE, HIGHWAY, STREET, DRIVING STRAIGHT, TURNING, ETC. NO WARNING. I ALMOST GOT REAR ENDED BECAUSE THIS PROBLEM EQUATES TO SOMEONE DRIVING ON THE HIGHWAY AND SLAMMING ON THEIR BRAKES WITH NO BRAKE LIGHTS!! I COULD HAVE LOST MY LIFE TODAY! TOYOTA IS AWARE AND HAS BEEN AWARE SINCE 2007 OF THE PROBLEM AND IS PLAYING WITH PEOPLES LIVES!! *TR

I TRADED MY 2012 TOYOTA TUNDRA FOR $17,000.00. BLUE BOOK 'TRADE-IN' VALUE WAS APPROXIMATELY $20,000.00 - $21,000.00 AT THE TIME. MY TRUCK HAD LOW MILEAGE AND WAS IN EXCELLENT CONDITION, EXCEPT FOR THE UNDERCARRIAGE RUST. I LOST $3,000.00 - $4,000.00 IN THE TRADE-IN.

A LIGHT CAME ON AND IT STARTED LOSING POWER. TOOK IT TO THE SHOP AND WAS TOLD IT WAS BAD GAS. I PUT THE CLEANER IN IT AND IT DIDN'T FIX IT. I HAD SOME BUDDIES TELL ME TO UNPLUG MY BATTERY BECAUSE IT SOUNDED LIKE A SAFETY FEATURE. SO I DID. THE LIGHT WENT OFF AND THE TRUCK ACTED RIGHT FOR A FEW MILES THEN STARTED DOING THE SAME THING. VEHICLE WAS IN MOTION ON THE HIGHWAY. MY BUDDIES REFERRED TO IT AS A "LIMP MODE" OR SOMETHING LIKE THAT. I WAS AFRAID TO HAVE IT WORKED ON BECAUSE I WAS TOLD IF THERE WAS A RECALL THE MANUFACTURER WOULDN'T BE LIABLE.

The truck has paint peeling from it. There is currently a recall out for other models of Toyota with the same paint type as mine. Toyota says that the Tundra is not affected by this recall. I took the truck to Toyota they took down a report and told me to call the cooperate office to report it as well.
Jul 18, 2022
THE BOTTOM CORNERS OF BOTH DOORS COME TO A VERY SHARP POINT. BOTH OF US HAVE SUSTAINED NASTY CUTS ON OUR SHINS WHEN GETTING IN AND OUT OF THE TRUCK SEVERAL TIMES. THERE SHOULD BE A DIFFERENT DESIGN TO REMOVE THE SHARP POINTS YOU CAN'T AVOID IT AT LEAST PUT DURABLE PROTECTION OVER THE SHARP EDGE.

MY 2012 TUNDRA CREW CAB HAS SEVERE RUST AT THE REAR AXLE MOUNTING PLATES OF THE BED. THE RUST IS CORRODING FROM THE UNDERSIDE THROUGH THE BED. TOYOTA INDICATES MY VIN IS NOT PART OF THE RECALL SERIES DESPITE THE BED RUST BEING IN THE EXACT LOCATION OF A PRIOR RECALL.
Nov 14, 2018
RUST IS BUBBLING UNDER PAINT ON TRUCK BED NEAR REAR T51 BED BOLTS WHERE THE SPOT WELDS ARE LOCATED. RUST APPEARS TO BE COMING OUT FROM UNDERNEATH SEAM SEALING IN AREA AS WELL. NO RUST IS VISABLE UNDERNEATH OF VEHICLE. A TSB ON THIS ISSUE WAS SENT OUT FOR 2007-2011 MODEL TUNDRAS THIS VEHICLE IS A 2012 WITH SAME ISSUE.
Aug 09, 2018
PREMATURE BED RUST AROUND MOUNTING BOLTS. VERY SIMILAR TO RECALL AND CLASS ACTION LAWSUIT FOR THE 2011 MODEL YEAR.

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.

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.
Apr 11, 2019
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.
Jan 26, 2018
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.

STEERING

The contact owns a 2012 Toyota Tundra. The contact stated while driving approximately 10 MPH, the vehicle experienced steering failure with abnormal popping sounds. There were no warning lights illuminated. The vehicle was towed to the residence. The vehicle had not been diagnosed or repaired. The manufacturer was not notified of the failure. The contact related the failure to NHTSA Campaign Number: 21E103000 (Steering). The approximate failure mileage was 156,485.

I WAS DRIVING AND ALL THE SUDDEN MY POWER STEERING WENT OUT. I WAS IN TRAFFIC AND ALMOST WAS IN AN ACCIDENT BECAUSE OF NO POWER STEERING. I IMMEDIATELY PULLED OVER AND LOOKED ON THE PASSENGER SIDE AND POWER STEERING FLUID WAS LEAKING OUT OF MY TIE ROD BOOT. I IMMEDIATELY GOT TO MY TOYOTA DEALER AND THEY AUTOMATICALLY KNEW WHAT IT WAS, THE RACK AND PINION BLEW OUT. SO CLEARLY IT'S A TOYOTA THING I FIGURED. I WAS ABLE TO GET IT FIXED BY MY INSURANCE COMPANY BUT I STARTED DOING RESEARCH ON FORUMS AND MANY FACEBOOK GROUPS DEVOTED TO TOYOTA TUNDRAS AND DAILY I SEE MORE AND MORE PEOPLE ARE HAVING ISSUES WITH THEIR RACK AND PINION GOING OUT AND DAYS AFTER MY FRIEND ALSO HAD HIS GO OUT ON HIS TUNDRA. THIS SEEMS TO BE A MAJOR PROBLEM TOYOTA HAS AND IT EITHER NEEDS TO BE RECALLED OR FIXED SOMEHOW SO PEOPLE CAN BE SAFE AND NOT ALMOST GET IN AN ACCIDENT LIKE I DID. WHEN TOYOTA EVEN ACKNOWLEDGES IT AND REFUSES TO NOT FIX IT, THAT THROWS THE RED FLAG RIGHT THERE AND THEY CLEARLY UNDERSTAND IT'S A PROBLEM. THE FIX AMOUNTED TO $1937 DOLLARS ALSO.

THE STEERING WHEEL DID NOT STAY CENTERED AND THE POSITION WOULD CHANGE. I NOTICED THAT WHEN I WAS STOPPED AND THE STEERING WHEEL WAS LOCKED THAT THE STEERING WHEEL HAD SOME MOVEMENT FROM SIDE TO SIDE. I CHECKED THE STEERING WHEEL LOCK DOWN NUT AND IT WAS TIGHT. THE STEERING WHEEL HAS A SPLINE BUSHING THAT MATCHES UP WITH A MATCHING SPLINE ON THE SHAFT SO I COULD NOT SEE HOW THIS COULD MOVE. I REMOVED THE LOCKING NUT SO I COULD SEE THE WHERE THE STEERING WHEEL AND SHAFT CONNECT TOGETHER. WITH THE NUT OFF I NOTICED THAT THE SPLINE BUSHING DID NOT MOVE BUT THE STEERING WHEEL DID MOVE ON THE BUSHING. THERE WAS A POTENTIAL DANGER OF THE STEERING WHEEL COMING LOOSE SO THAT I WOULD LOSE CONTROL OR WORSE YET THE STEERING WHEEL COULD COME COMPLETELY OFF THE COLUMN. THIS PROBLEM CAN EASILY BE CHECKED AS I DID WITH THE STEERING WHEEL IN THE LOCKED POSITION. IF YOU HAVE ANY MOVEMENT OF THE STEERING WHEEL IN THE LOCKED POSITION GET IT CHECKED IMMEDIATELY.

TOYOTA TUNDRA POWER STEERING RACK AND PINION FAILURE. WHILE DRIVING MY TRUCK THE POWER STEERING RACK AND PINION FAILED. I HEARD A POP SOUND AND PULLED OFF THE CITY ROAD TO INSPECT MY VEHICLE. UPON DOING SO I NOTICED THE STEERING WAS DIFFICULT TO MANIPULATE AND UPON INSPECTION FOUND POWER STEERING FLUID ACTIVELY LEAKING OUT OF THE FRONT PASSENGER SIDE BELLOWS BOOT. MY VEHICLE HAD APPROXIMATELY 47,000 MILES AT THIS TIME.

MY TRUCK IS A 2012 TOYOTA TUNDRA 4X4 LIMITED. IT HAS 100,000 MILES ON IT. I TYPICALLY ONLY DRIVE IT ON THE WEEKENDS. I WAS DRIVING AND MADE A TURN, ALL OF A SUDDEN I LOST POWER STEERING. THE ACCORDION BOOT ON THE PASSENGER SIDE WAS FULL OF POWER STEERING FLUID. IT BLEW A SEAL ON THE STEERING ROD. THE WHOLE RACK AND PINION HAD TO BE REPLACED. 18 HOUR LABOR JOB, AND WITH PARTS $3000.00. I ALMOST GOT INTO A ACCIDENT BECAUSE I COULDN'T TURN IT. YOU HAVE TO DROP THE ENGINE ASSEMBLY TO CHANGE IT THAT'S WHY IT COST SO MUCH. THIS HAS TO BE A FACTORY DECFECT. ANY INPUT?

A GRINDING NOISE BEGAN TO DEVELOP IN THE REAR END OF THE TRUCK. THE NOISE WAS MOST NOTICEABLE BETWEEN 30 AND 60 MPH. I TOOK THE TRUCK TO A TOYOTA DEALERSHIP FOR DIAGNOSIS AND THEY DETERMINED THE REAR WHEEL BEARINGS HAD FAILED. THESE BEARINGS ARE SEALED, REQUIRE NO MAINTENANCE, AND SHOULD BE DESIGNED TO LAST THE LIFETIME OF THE TRUCK. THIS IS A SAFETY CONCERN BECAUSE A BEARING FAILURE COULD LEAD TO LOSS OF VEHICLE CONTROL AND AN ACCIDENT. I HAVE FOUND A NUMBER OF SIMILAR INCIDENTS REPORTED ON INTERNET TUNDRA FORUMS, WHICH INDICATES THIS IS NOT AN ISOLATED PROBLEM.

WHILE DRIVING DOWN THE ROAD THE TRANSMISSION HAS PROBLEMS SHIFTING INTO 1ST AND 2ND GEAR. THE TRANSMISSION IS A LITTLE SLUGGISH WHILE SHIFTING AND IN SOME CASES EVEN JUMPS WHILE SHIFTING INTO 1ST AND 2ND GEAR. HAVE HAD IT LOOKED AT AND WAS TOLD HAVE TO REPLACE THE WHOLE TRANSMISSION. I HAVE A COWORKER WHO HAD SOME PROBLEMS WITH HIS TRANSMISSION ON HIS TUNDRA, AND HE ENDED UP TRADING IT IN, BECAUSE IT COULD NOT BE FIXED. I HAVE THE PAPERWORK FROM GETTING IT CHECKED IF IT IS NEEDED

I TOOK MY WIFE AND DAUGHTER ON A COUPLE OF RUNS THREW THE MUD IN OUR 2012 TOYOTA TUNDRA CREWMAX 4X4 TRD. THE RUNS WERE NO LONGER THAN 2-3 MINUTES OF FUN WITH ZERO PROBLEMS. I DID NOT HAVE TIME TO RUN OUR TRUCK THREW A CAR WASH. I PLANNED ON GETTING IT WASHED THE NEXT DAY AFTER WORK. ON MY TO WORK THE FOLLOWING DAY OUR TRUCK SHOWED NO SIGNS OF PROBLEMS UNTIL I ENTERED THE FREEWAY AND CONTINUED TO ACCELERATE. AT THAT POINT OF TIME I COULD "FEEL" THE TRANSMISSION WAS NOT SHIFTING CORRECTLY . I CALLED AVONDALE TOYOTA IMMEDIATELY INFORMING THEM THERE WAS SOMETHING WRONG WITH MY TRANSMISSION. THEY SET AN APPOINTMENT UP FOR FRIDAY THE 7TH OF MARCH. I INFORMED TOYOTA THAT I WOULD PREFER TO DROP THE VEHICLE OFF WHEN I FINISHED WORK BECAUSE I FELT LIKE DRIVING IT WOULD ONLY CAUSE MORE ISSUES IF ANY. TODAY I RECEIVED A PHONE CALL FROM AVONDALE TOYOTA INFORMING THE TRANSMISSION "BURNED UP" AND IS NOT UNDER WARRANTY EVEN THOUGH OUR VEHICLE IS UNDER WARRANTY. THEIR WARRANTY REP BASED HIS OPINION ON PICTURES, STILL DIRTY FROM GOING THREW MUD, AND CONCLUDED THE TRANSMISSION WAS "ABUSED" AND TOYOTA IS NOT RESPONSIBLE FOR "ABUSE." I IMMEDIATELY WENT TO AVONDALE TOYOTA AND SPKE WITH[XXX] AND THE MECHANIC WHO LOOKED AT THE TRANSMISSION. THE MECHANIC INFORMED ME THAT ALL FLUID LEVELS WERE NORMAL, TEMPERATURE LEVELS ARE NORMAL AND NO TRANSMISSION CODES WERE TRIPPED. ZERO!!! A GEAR BROKE IN THE TRANSMISSION AND TELLING CUSTOMERS THE TRANSMISSION "BURNED" UP IS AN EASIER WAY TO INFORM CUSTOMERS.IT IS THEIR ASSUMPTION THAT I GOT STUCK IN MUD AND "ATTEMPTED TO ROCK THE VEHICLE BY MOVING THE SHIFTER BACK AND FORTH FROM DRIVE AND REVERSE WHILE I WAS ON THE ACCELERATOR." I INFORMED THE AVONDALE THAT WAS NOT THE CASE. I COULD OF SIMPLY TOOK OUR VEHICLE TO THE CAR WASH, HAD IT CLEANED AND CONTACTED TOYOTA AND TOLD THEM MY TRANSMISSION IS ACTING UP. LYING SEEMS THE WAY TO GO THESE DAYS. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

THE PASSENGER SIDE AIRBAG CAME ON WHEN MY SON AND I WENT ON A TRIP TO OUR CABIN. WE STOPPED TO GET GAS, MY SON GOT OUT OF THE TRUCK AND THE LIGHT CAME ON. I TURNED THE IGNITION OFF GOT GAS, AND WHEN I STARTED THE TRUCK AGAIN THE AIRBAG LIGHT REMAINED ON. I AGAIN TURNED THE TRUCK OFF AND STARTED IT AGAIN. MY SON GOT OUT AND THEN GOT BACK INTO THE TRUCK. I TOOK THE CONCERN TO THE DEALER AND THEY RESET THE AIRBAG LIGHT. AFTER THE AIRBAG TURNED OFF ON US AT ALMOST THE EXACT SAME PLACE ON OUR TRIPS TO THE CABIN 5 MORE TIMES OVER A YEAR WITH NO FIX TO THE PROBLEM I ASKED THE DEALER TO COME UP WITH A PLAN TO ADDRESS THE ONGOING SAFETY PROBLEM. MY REP. AT THE DEALERSHIP SAID THE TOYOTA CORPORATE REP. WILL STOP IN TO THE DEALERSHIP IN A MONTH OR SO AND THEY WILL CALL ME TO MEET WITH HIM. AFTER THREE MONTHS WITH NO CONTACT I CALLED THE DEALERSHIP, WHEN NO ONE CALLED ME BACK I WENT TO THE DEALERSHIP. MY REP. WAS OUT FOR THE SUMMER AND ANOTHER REP.

AFTER TWO WEEKS OF TRYING TO GET A PLAN FROM HER SHE TOLD ME THAT THEY WERE NOT RESPONSIBLE BECAUSE THE PASSENGER WAS TOO HEAVY FOR THE AIRBAG AND THE AIRBAG SENSOR. SHE SAID THE FEDERAL GOVERNMENT SETS THE STANDARDS AND THERE IS NOTING THEY CAN DO TO ADJUST THEM. I ASKED IF SHE COULD SEND ME THE AIRBAG SENSOR WEIGHT SINSITIVITY SETTINGS SHE DID NOT RESPOND TO THE REQUEST. I THEN ASKED HER TO PUT TOYOTA'S POSITION IN WRITING, AND THE REP. TOLD ME THAT "YOUR MAINTENANCE RECEIPT IS YOUR COMMUNICATION". THAT IS THE ONLY THING THEY WILL GIVE ME. I HAVE A DANGEROUS SITUATION WITH THIS AIRBAG, AND TOYOTA WILL NOT TAKE RESPONSIBILITY FOR THE DEFECT. I NEED HELP BEFORE SOMEONE GETS KILLED HERE.

ON NUMEROUS OCCASIONS WHILE DRIVING, MY 2012 TOYOTA TUNDRA SUDDENLY LOST ACCELERATION POWER AND EXPERIENCED THE ENGINE FAILURE KNOWN AS "FAIL-SAFE" OR "LIMP-HOME" MODE. AS EVIDENCED BY TOYOTA T-SB-0160-11, WARRANTY POLICY BULLETINS, AND WARRANTY ENHANCEMENT PROGRAMS, TOYOTA IS WELL AWARE OF THIS SERIOUS DESIGN FLAW AND SAFETY ISSUE, YET HAS CHOSEN TO REPAIR OR COMPENSATE ONLY A SELECT FEW. THE PARTS THAT HAD TO BE REPLACED AFTER MY VEHICLE REPEATEDLY WENT INTO 'FAIL-SAFE / LIMP-HOME' MODE CORRESPOND DIRECTLY WITH THE PART NUMBERS REFERENCED IN TOYOTA WARRANTY POLICY BULLETIN POL17-02 WHICH COVERS THIS DEFECT IN OTHER MODELS, BUT NOT IN MY 2012 MODEL. MY OUT-OF-POCKET COST TO REPAIR THIS MANUFACTURER'S DEFECT WAS $3034.87. THIS A KNOWN AIR INJECTION SYSTEM WATER INTRUSION DEFECT AND COMMON SAFETY COMPLAINT AT THE NHTSA AND ON MULTIPLE TOYOTA FORUMS, AFFECTING NUMEROUS 2012 TUNDRA'S WHICH TOYOTA IS REFUSING TO ACKNOWLEDGE AND COMPENSATE FOR. I HAVE WRITTEN SEVERAL LETTERS TO BOTH THE CEO OF TOYOTA AND THE TOYOTA CUSTOMER EXPERIENCE CENTER REQUESTING REIMBURSEMENT OF MY REPAIR COSTS AND HAVE BEEN DENIED TWICE; THE FIRST DENIAL IN WRITING, THE SECOND DENIAL VIA TELEPHONE. I REQUEST THE NHTSA INVESTIGATE THIS SERIOUS SAFETY ISSUE TO PROTECT THE LIVES OF OTHERS DRIVING THESE DANGEROUS VEHICLES. TOYOTA HAS AN ETHICAL AND SAFETY OBLIGATION TO THE CONSUMER TO REMEDY THIS DEFECT AND TO COMPENSATE THOSE OF US WHO HAVE HAD TO BEAR THE FINANCIAL BURDEN OF THEIR FAILURE TO CORRECT THIS WELL-KNOWN ISSUE. *BF

DRIVER'S SEAT FRAME (BASE) BEGAN INTERMITTENTLY POPPING WHICH PROGRESSED TO A CONSISTENT POPPING FELT EVERY TIME THE VEHICLE CORNERED AT SPEED OR WEIGHT SHIFTED IN THE DRIVER'S SEAT. THE PROBLEM WAS CONFIRMED BY DEALERSHIP AND AN ADJUSTMENT MADE TO THE SEAT RAIL ALIGNMENT PIN. FOR SEVERAL MONTHS, THE PROBLEM APPEARED TO BE FIXED. HOWEVER, THE PROBLEM ULTIMATELY RETURNED WITH A SIMILAR POPPING NOISE. I ALLOWED IT TO PROGRESS UNTIL THE DEALERSHIP COULD REPRODUCE THE POPPING NOISE IN THE DRIVER'S SEAT FRAME (BASE). THE PROBLEM WAS IDENTIFIED THE SECOND TIME AS A CRACKED WELD IN THE FRAME NEAR THE POINT WHERE THE SEAT BACK AND BASE ARE CONNECTED. THE DEALERSHIP ORDERED AND REPLACED THE ENTIRE SEAT FRAME WITH A NEW ONE. THE MILEAGE AT THE TIME OF REPAIR WAS 23500 MILES. I AM DOCUMENTING THE ISSUE BECAUSE I HAVE NOTICED SEVERAL OTHERS COMPLAINING ON TRUCK FORUMS OF POPPING IN THE SEAT FRAME.

2012 TUNDRA 4.6 V8 MY TRUCK WILL GO INTO LIMP MODE AND THE 4LO LIGHT FLASHES, CHECK ENGINE, AND TRAC OFF LIGHTS WERE ALL ON. ALMOST COMPLETE LOSE OF POWER WILL HAPPEN. IN TRAFFIC I END UP BLOCKING EVER VEHICLE BEHIND ME, BECAUSE THE TRUCK WILL NOT REACH THE SPEED LIMIT. IF THERE IS A HILL THEN THE TRUCK BARELY MOVES GOING UP THE HILL. AFTER LOOKING ONLINE I SAW IT'S A PRETTY COMMON PROBLEM ON TOYOTA WITH THE SECONDARY AIR INJECTION PUMP SEIZING. I CHECKED IT WITH THE CODE READER AT A LOCAL SHOP AND THE GUY CONFIRMED IT, CODE P2240 "AIR INJECTION SWITCHING VALVE STUCK OPEN BANK 1." HE TOLD ME HE USED TO WORK FOR TOYOTA AND KNEW THERE WAS THE EXTENDED REPAIR ON THIS ISSUE BUT COULDN'T RECALL THE SPECIFICS. I WENT INTO TOYOTA AND UNFORTUNATELY THEY WILL NOT COVER IT FOR MY TRUCK AFTER THEY RAN MY VIN NUMBER. IT SEEMS LIKE A LOT OF TUNDRAS WITH THE 5.7L MOTOR ARE COVERED BUT THE 4.6L MOTORS ARE NOT. I WAS INFORMED BY TOYOTA THAT IN THE FUTURE IT MIGHT BE COVERED.

THEY HOOKED UP A ANALYSIS COMPUTER AND CAME BACK WITH MAINTENANCE CODE P2432, SECONDARY AIR PUMPS AND SECONDARY AIR PUMP VALVES. I FOUND OUT THAT THIS HAS BEEN AN ONGOING ISSUE WITH TOYOTA TUNDRAS GOING BACK TO 2007 MODELS. THE WARRANTY HAS BEEN EXTENDED ON 2007 - 2010 MODELS BUT NOT NEWER MODELS WHICH ARE STILL EXPERIENCING THE SAME PROBLEM.I FEEL THIS PROBLEM CONSTITUTES A POTENTIALLY DANGEROUS SAFETY HAZARD DUE TO THE DRASTIC REDUCTION IN POWER WHICH COULD CAUSE AN ACCIDENT DEPENDING ON WHEN THE PARTS IN QUESTION FAIL.

MY 2012 TOYOTA TUNDRA IS EQUIPPED WITH TOYOTA'S VEHICLE STABILITY CONTROL (VSC). ONE OF THE FEATURES OF THE VSC IS WHEN THE COMPUTER PERCEIVES A LOSS OF TRACTION, THE COMPUTER (WITHOUT THE DRIVER'S CONSENT) ATTEMPTS TO CORRECT THE LOSS OF TRACTION BY BRAKING AND/OR ENGAGING ONE OR BOTH OF THE FRONT TIRES. IN NOVEMBER OF 2016, THE VSC ON MY TUNDRA (WITH ONLY 43K MILES) BEGAN TO FAIL AND INSTEAD OF BECOMING INOPERABLE AND DOING NOTHING, THE VSC ATTEMPTS TO ENGAGE THE FRONT TIRE(S) DURING ROUTINE TURNING MOVEMENTS. THIS CAUSES A JERKING SENSATION IN THE STEERING WHEEL AND THE VEHICLE PULLS SHARPLY TO ONE-SIDE. THIS COULD CAUSE A LOSS OF CONTROL. THE VEHICLE HAS BEEN TO THE DEALER THREE TIMES AND I HAVE SPENT NEARLY $2,800 TRYING TO CORRECT THE PROBLEM. TO DATE, TOYOTA HAS BEEN UNABLE TO CORRECT THE PROBLEM OR DISABLE THE FEATURE. IT IS MY OPINION THE VSC SYSTEM IN THE 2012 TUNDRA IS UNSAFE. THIS IS NOT ONLY BASED ON THE FACT I AM THE OWNER OF A DEFECTIVE TUNDRA, PRIOR TO RETIRING IN NOVEMBER 2015; I WORKED FOR THE CALIFORNIA HIGHWAY PATROL FOR MORE THAN 27 YEARS AS AN OFFICER AND SERGEANT. I INVESTIGATED NUMEROUS TRAFFIC COLLISIONS, WORKED IN SPECIALIZED INVESTIGATION UNITS AND RECEIVED ADVANCED TRAINING IN TRAFFIC ACCIDENT RECONSTRUCTION. I KNOW FIRSTHAND THAT A SUDDEN AND UNEXPECTED PULL ON A STEERING WHEEL, SUCH AS I AM EXPERIENCING IN MY TUNDRA, COULD CAUSE A DRIVER TO LOSE CONTROL. THEREFORE, IT IS MY OPINION BASED ON THE AFOREMENTIONED THAT THE VSC SYSTEM ON THE 2012 TOYOTA TUNDRA IS DEFECTIVE AND POTENTIALLY DANGEROUS.

My power steering gear blew its seal on the passenger side losing all power steering fluid and almost making me crash into a car next to me, and Toyota refuses to cover it stating that I hadn't had the steering gear replaced prior to whenever their dates were this is clearly faulty equipment and faulty machine work on the steering gear itself. why won't Toyota cover it? I tried contacting One Toyota and Downtown Toyota here in Oakland California and they told me that they wanted $250 to inspect my vehicle and that I would definitely have to pay for it because my vehicle was not under recall it states it is a recall if you look it up.It is worded recall if they're not going to cover it sounds like they're trying to back out of covering it until someone gets seriously hurt or killed like I almost did, I will never buy another Toyota again as long as I live because clearly they don't care about the faulty equipment on their vehicles that's going to hurt or kill someone. All they care about is the mighty dollar and that's just wrong. Safety has gone rite the window and if anyone reading this is thinking about buying a Toyota, I would seriously think twice.

The contact owns a 2012 Toyota Tundra. The contact stated that while plowing his driveway, there was an abnormal burning odor detected. The vehicle suddenly lost power. There were no warning lights illuminated. The vehicle was towed to the local dealer where it was diagnosed and determined that oil was needed. The mechanic became aware that oil was dripping through a small crack on the cam shaft on the right cylinder bank onto the exhaust manifold. The contact was informed that the engine wiring harness was burned. The mechanic recommended that the engine and transfer case be replaced. The vehicle was not repaired. The manufacturer was contacted, and the contact was informed after an investigation, that there was no evidence of a defect. The claim was denied. There was no additional assistance provided.

AFTER ABOUT FOUR DAYS OF RESEARCH I FOUND THIS IS A COMMON PROBLEM IT NOT JUST MY VEHICLE BUT MULTIPLE YEARS AND MOTOR SIZES. TOYOTA APPARENTLY COVERED CERTAIN YEAR MODELS/VINE BUT WHEN CALLING REGARDING MINE THEY SAID MY VEHICLE WASN'T COVERED EVENING THOUGH THERE ARE THOUSAND OF CONSUMERS HAVING THE EXACT SAME ISSUE. THIS ISSUE IS ALSO AN EXPENSIVE REPAIRS COST UPWARDS TO $3,500-$400 TO FIX.

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).

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.

ON 12/24/2012 AROUND 04:00HRS I STRUCK AN ADULT MOOSE IN BEAR LAKE, CANADA WITH THE FRONT END OF MY WIFE'S 2012 TOYOTA TUNDRA CREWMAX ON THE BRITISH COLUMBIA HIGHWAY. THE CONDITION OF THE ROAD WAS SNOW AND ICE BUT WE HAD RECENTLY PURCHASED AFTERMARKET RIMS AND TIRES ON 12/18/2012 IN CALIFORNIA; 18IN MB VOTEX RIMS WITH BFG ALL TERRAIN TIRES. THE TRACTION OF THESE TIRES BOOSTED MY CONFIDENCE IN TRAVELING AT SPEEDS OF 30-40MPH AT NIGHT. WE HAD TRAVELED ALL THE WAY FROM GEORGIA WITHOUT SEEING ANY ANIMALS AT NIGHT. THE HID HEAD LAMPS GAVE ME A FALSE SENSE OF SECURITY NAVIGATING THROUGH THE NIGHT IN ORDER TO MAKE THE FINAL LEG TO ANCHORAGE, AK FOR CHRISTMAS DAY. TO MY SURPRISE, A MOOSE TIPTOED FROM THE WOODS ON MY RIGHT ABOUT 20 FEET AHEAD OF ME AS I INTENDED TO PRESS ON PASS IT. BUT ALL OF A SUDDEN IT GOT SPOOKED AND DARTED INTO MY PATH. I STRUCK THE ANIMAL BROAD SIDE WITH THE FRONT END OF THE TRUCK KNOCKING IT INTO THE ENGINE BAY. INITIALLY I THOUGHT THE CONTACT WAS NOT SEVERE BUT INSPECTION PROVED OTHERWISE. THE HOOD WAS CRUMPLED UP UNTO THE WINDSHIELD, AND THE RADIATOR AND MOTOR WAS PUSHED SO FAR BACK THAT IT WAS NO LONGER DRIVABLE. I BELIEVE MY SPEED WAS AROUND 30MPH UPON IMPACT WHICH SURPRISED ME THAT THE ANIMAL WAS DEAD. THE TRUCK WAS TOWED TO A LOCAL BODY SHOP FOR AN INSURANCE ESTIMATE AS A TOTAL LOSS. I WAS CONCERNED AS TO WHY THE AIRBAGS DID NOT DEPLOY SINCE THE DAMAGES WAS SO GREAT. THE TECH EXPLAINED THAT THE SENSORS FOR THE AIRBAGS ARE LOCATED BEHIND THE BUMPER OF THE TRUCK WHERE IMPACT WAS MINIMAL. BECAUSE THE CONTACT TO THE MOOSE KNOCKED HIM OFF HIS LEGS THE LARGE BODY FELL INTO THE ENGINE COMPARTMENT AND COULD HAVE BEEN FATAL HAD IT A FULL RACK OF ANTLERS. THANK GOD HE DID NOT! THOUGH WE HAVE PURCHASED A 2013 REPLACEMENT OF THE SAME TRUCK, THE AIRBAGS NOT DEPLOYING IS STILL A CONCERN AS A DESIGN FLAW AND NEED TO BE ADDRESSED. *TR

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

THE 9/8/13 ACCIDENT INVOLVED A SEVERE SIDE IMPACT. BOTH DRIVER SIDE DOORS WERE IMPACTED AND THE CENTER FRAME POST REQUIRED REPLACEMENT. HOWEVER, THE SIDE IMPACT AIR BAGS DID NOT DEPLOY, WHICH SHOULD HAVE HAPPENED. THE TRUCK IS STILL IN THE SHOP AS OF 9/25/13 BECAUSE THERE ARE PROBLEMS WITH THE ONBOARD COMPUTER RECOGNIZING THE SIDE AIR BAGS. I AM CONCERNED WITH THE SAFETY OF THE VEHICLE AIR BAG SYSTEM. *LN UPDATED 1/6/2013 *JS
