2012 TOYOTA TUNDRA Engine Problems

Wife was driving truck and immediately went into limp mode on the highway. Check engine light came on, no accelerating then died. Had to get it towed. This is the 3rd incident with this issue.

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.

Mileage: 98,000

Computer software issues. Flex full engine.

The engine leaks oil in front of the faulty designed cam tower seal and leaks on the manifold. This caused smoke to come from the oil burning off.

Secondary air injection pump has high rate of failure, recalls in older models. Has caused truck to go into limp mode. Could cause serious accident/fatality if vehicle suddenly goes into limp mode on highway. This has happened on multiple occasions in forums I’ve read. Known problem by Toyota that isn’t being addressed.

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.

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.

Mileage: 95,899

TL* THE CONTACT OWNS A 2012 TOYOTA TUNDRA. THE CONTACT STATED THAT THE VEHICLE WAS PURCHASED WITH THE CHECK ENGINE WARNING LIGHT ILLUMINATED. THE VEHICLE WAS REPAIRED AT JOHN HARVEY TOYOTA (2901 BENTON RD, BOSSIER CITY, LA 71111, (318) 741-1337). THE CONTACT STATED THAT AFTER THE VEHICLE REPAIRED, THE TRANSMISSION FAILED AND THE CONTACT RETURNED THE VEHICLE TO THE SAME DEALER WHERE THE TRANSMISSION WAS ALSO REPAIRED. THE CONTACT STATED THAT THE VEHICLE FAILED TO ACCELERATE ABOVE 25 MPH AND WAS TAKEN TO AN INDEPENDENT MECHANIC TO BE DIAGNOSED. THE MECHANIC DETERMINED THAT THE SECONDARY AIR INJECTION SYSTEM FAILED AND NEEDED TO BE REPAIRED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 115,000.

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.

CHECK ENGINE LIGHT WENT ON. GOT A CODE P0418-VEHICLE WILL GO LIMP/NOT ABLE TO GO OVER 25MPS. TOYOTA HAS A WARRANTY REPAIR PROGRAM IN PLACE FOR ALL 2012 TUNDRAS WITH A 5.7 SIZE BUT NOT MINE BECAUSE IT IS A 4.6 EVEN THOUGH IT IS THE EXACT SAME PROBLEM!!! *TR

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

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

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.

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.

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.)

WHEN CRANKING THE VEHICLE ALL OF A SUDDEN AS OF 5 DAYS AGO THE CHECK ENGINE LIGHT APPEARS ALONG WITH 'TRACK OFF' INDICATOR. THIS THROWS THE TRUCK IN 'LIMP' MODE DECREASING THE POWER OF THE VEHICLE BY 50%. THIS HAPPENED THE FIRST MORNING AND I WAS ENTERING A ON RAMP TO GET ON THE HIGH FROM MY NEIGHBOR AND ALMOST GOT PLOWED OVER DUE TO NOT BEING ABLE TO PROPERLY ACCELERATE TO HIGHWAY SPEEDS WHILE ENTERING THE RAMP. I HAD A TECHNICIAN CHECK THE ISSUE AND WAS TOLD IT HAS TO DUE WITH THE 'SECONDARY AIR INJECTION VALVE' FAILING. 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. TOYOTA IS AWARE OF THE PROBLEM AND APPARENTLY DOESN'T CARE THAT IT ALSO CAUSE SAFETY ISSUES WITH THE VEHICLE NOT HAVING PROPER POWER TO OPERATE. THIS IS A MANUFACTURING DEFECT PLAN AND SIMPLE.

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.

I WAS COMING OFF AN ENTRANCE RAMP MERGING INTO TRAFFIC ON TO A 4 LANE HIGHWAY WHEN MY CHECK ENGINE LIGHT, TRAC OFF LIGHT AND BLINKING 4 LOE CAME ON. THE ENGINE WENT INTO LIMP MODE GREATLY REDUCING MY POWER AND IT FELT LIKE MY STEERING CONTROL GOT LOOSE. I HAD TO PULL OFF THE ROAD TO KEEP FROM BEING RUN OVER BY FASTER TRAFFIC. I WAS ABLE TO MAKE IT TO THE NEXT OFF RAMP AND GET TO A MECHANICS SHOP. THEY HOOKED UP A ANALYSIS COMPUTER AND CAME BACK WITH MAINTENANCE CODE P2432, SECONDARY AIR PUMPS AND SECONDARY AIR PUMP VALVES. UPON FURTHER RESEARCH OF THIS ISSUE I HAVE 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. MY VEHICLE IS CONSIDERED LOW MILEAGE FOR A 2012 WITH ONLY 79,786 MILES. 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.

SECONDARY AIR INJECTION PUMP AND SECONDARY AIR INJECTION SWITCHING VALUE CAUSING CHECK ENGINE AND TRAC CONTROL LIGHTS TO COME ON. I WAS TOLD BY THE DEALER THAT THE SAME PIECE AND DESIGN WAS RECALLED ON THE 2011 BUT NOT THE 2012 TUNDRA. IT COMES ON AND OFF BUT WHEN IT IS ON IT FEELS LIKE THAT THERE IS A LIMP MODE MAKING IT DIFFICULT TO GET UP TO SPEED ON THE HIGHWAY. THE STEERING FEELS DIFFERENT WHICH I THINK IS THE TRACTION CONTROL.

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.

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 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.

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.

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.

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.

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.

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

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

FLEX FUEL MODELS SOLD BY GULF STATES TOYOTA HAVE AN ISSUE WHERE THE ENGINE'S COMPUTER THINKS THERE IS E85 FUEL (OR AN ALCOHOL CONCENTRATION THAT IS MUCH HIGHER THAN ACTUAL) IN THE SYSTEM WHEN THERE IS NORMAL 10% OR LESS GASOLINE ACTUALLY PRESENT. THIS CAN CAUSE ROUGH COLD STARTS/IDLE, POWER LOSS, SUDDEN RPM/POWER DROPOUT, MISSING, AND LESSENED FUEL ECONOMY, ETC. (DIFFERENT SYMPTOMS FOR DIFFERENT TRUCKS). AT THIS TIME THERE IS NO FINAL FIX AND NO AVAILABLE SERVICE BULLETIN. THE ONLY GUIDANCE AT THIS TIME IS TO HAVE YOUR DEALER SEE WHAT ALCOHOL CONCENTRATION YOUR TRUCK IS RUNNING AND RE-FLASH THE COMPUTER IF THE READOUT IS INCORRECT. DEALER ALSO STATES TO NOT ACCELERATE AGGRESSIVELY. I HAVE SERVICE SCHEDULE ON 3/9/13 TO ADDRESS THE PROBLEM FOR THE THIRD TIME. I PURCHASED THE VEHICLE NEW ON 11/23/12. *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
