2011 TOYOTA TUNDRA Engine Problems

The contact owns a 2011 Toyota Tundra. The contact stated while driving at an undisclosed speed, the check engine waning light illuminated. The vehicle was taken to the dealer to be diagnosed. The contact was informed of secondary error in the injection system caused by water intrusion. The contact was also informed that there was a recall on the vehicle however, the vehicle had exceeded the mileage limitation. The vehicle was repaired but the failure persisted. The manufacturer was not made aware of the failure. The approximate failure mileage was 219,000.

Mileage: 219,000

* According to the different computers codes the issue is Secondary Air Injection Pump failure. *Driving on the highway I had the limp mode which created a drastic velocity drop from 70 mph to 40 mph which created a situation that almost ended up in having another car hitting me from behind. this incident occurred a coupled of times in highway but in most cases just when starting a cold engine * problem is widely encountered online by other users [XXX] [XXX] [XXX] * check engine and track lights off * First time it occurred is 10/02/2023 INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

1. The secondary air injection valve and/or air injection pump. 2. Sometimes the vehicle will go into "limp" mode and only go 35 mph. If the switch valve is stuck "closed" like mine, the car may not be able to dilute the exhaust fumes and the fumes and travel into the cabin of the vehicle. 3. Yes, check engine light code was read as P2441. 4. No, the vehicle can not be driven at this time. 5. No, and around July 24th the check engine light came on. The symptoms continued to get worse. In short, Toyota has issued extended warranties and reimbursements for this design flaw for Tunda's 2007-2010. The design flaw being the air pumps allow water and debris to be sent into the air injection valves. My truck being a 2011 was never alerted to this issue or covered due to the year of my vehicle. The issue is my truck is the SAME generation truck as the 2007-2010 trucks. Which means I too have the design flaw as well but Toyota is refusing to fix their mistakes. After further inspection of my truck, see attached pictures, there is obvious water in the valve system and it has been rusted as well (unable to clean it). My issue is Toyota only covering half of the generational years for a design flaw that is also in the other half. These repairs can range from $2k-$4k and it seems as Toyota only made the extension to the most relevant truck years at the time and left everyone else behind. It is very distributing that a large manufacturer would cut corners like this, for a flaw that was their design.

The contact owns a 2011 Toyota Tundra. The contact stated that while a routine inspection was being performed on the vehicle, he was informed that engine oil was found on the heat shield. The dealer diagnosed the vehicle and determined that the passenger’s side cam-tower was leaking oil and needed to be replaced. The vehicle had not been repaired. The manufacturer was made aware of the failure. The approximate failure mileage 32,000.

The contact owns a 2011 Toyota Tundra. The contact stated while driving approximately 55-70 MPH, the check engine warning light illuminated and the vehicle started losing power. The contact veered to the side of the road and turned off the vehicle. The contact restarted the vehicle and was able to continue driving. Additionally, the contact stated that upon starting the vehicle, the accelerator pedal was depressed; however, there was a delay in the vehicle response. The contact stated that the failure reoccurred several times while driving. The contact stated that the vehicle shifted into LIMP mode. The vehicle was taken to a local Pep Boys who provided diagnostic test codes to the contact but did not physically diagnose the vehicle. The vehicle was taken to the dealer. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and informed the contact they could not assist as the vehicle had not been diagnosed by the dealer. The failure mileage was approximately 165,000.

Well known issue with V8 Air intake pump and assembly causes truck to go into limp mode. Very dangerous in Atlanta traffic. Toyota enhanced warranty but did not recall. My repair was $3000 as I was 3 weeks out of warranty.

-Secondary Air Injection System Failure. -Limp Mode truck unable to go above 60km/hr when on hi-way with 100km/hr speed posted.No power to go up hills. -Made appointment with Alpine Toyota, Cranbrook, BC for May 20, 2021. Explained problem to service adviser. Mentioned truck was in limp mode , I will pull battery terminal to reset code in order to get out of limp mode so I can drive 105km to dealership for repair. Alpine Toyota worked on truck for one hour wile I waited. After one hour Alpine Toyota informed me they could not repair truck without a code present. I replied I explained to service when making appointment that I had to reset code in order to drive truck to dealership. Toyota replied drive truck until it goes into limp mode, then have it towed to us at your cost in order for us to diagnose problem otherwise we cannot help you. -Alpine Toyota refused repair. -Limp mode, illumination of check engine, 4Lo, Traction light. -Occurred May 11, 2021, (211 256km on truck) - pulled battery terminal to reset code, replaced new fuel cap. -Occurred May 16, 2021, (211 516km) - pulled battery terminal to reset code. -Occurred May 19, 2021 - pulled battery terminal to reset code.

UNDER BULLETIN POL17-02, MY TRUCK FALLS UNDER THE PROGRAM 10 YEARS AND 150,000 MILES. I CONTACTED THE DEALER AND THEY ADVISE MY TRUCK ISN'T COVERED. I HAD THE PROBLEMS THAT WAS INDICATED UNDER THE WARRANTY ENHANCEMENT PROGRAM. I HAD THE TRUCK REPAIRED AND I AM LOOKING FOR A REIMBURSEMENT CONSIDERATION

THE AIR PUMP WAS FAILED AT TRAFFIC LIGHTS AROUND 22,000 MILES. THE VEHICLE WAS MOVED AT LOW SPEED 10MPH TO DEALER. IT WAS FIXED. RIGHT NOW AT 27,300 MILE TOWER CAM SEAL WAS LEAKED AND OIL WAS DRIPPED ON EXHAUST WITH SMELL AND SMOKED IN COLD DAYS. IT IS VERY SCARY DANGER. I DO NOT FEEL SAFE ABOUT MY TRUCK. I DID CALL TOYOTA CORPORATE FOR RECALL, BUT THEY DENIED! THERE IS NO WAY THAT THE CAM TOWER SEAL IS LEAKED BUT IT IS STARTING DRIPPING MORE NOW. I BROUGHT THE CAR TO DEALER AND THE SERVICE ADVISOR TOLD ME TO CALL THEM AGAIN. TOYOTA CORPORATE KEEP DENYING!! I URGED TOYOTA COMPANY IMMEDIATELY TAKE CARE OF THEIR FAIL PRODUCT. IT MAY GET FIRE BECAUSE THE OIL DRIPPING ON THE EXHAUST, PASSENGER SIDE. PLEASE SERIOUSLY TAKE CARE OF THE PROBLEM.

VEHICLE HAS DEVELOPED A CAM TOWER LEAK DUE TO IMPROPER SEALING OF MATING SURFACES DURING ENGINE ASSEMBLY CAUSING OIL TO LEAK ONTO EXHAUST MANIFOLDS CAUSING A POTENTIAL FOR ENGINE COMPARTMENT FIRE ACCORDING TO SERVICING DEALER. VEHICLE HAS LESS THE 45,000 MILES AND HAS HAD REGULAR SERVICE BY AUTHORIZED DEALER. DEALER REPRESENTATIVE STATES THAT IF PROBLEM PERSISTS VEHICLE WILL NOT PASS STATE MANDATED SAFETY INSPECTION. OIL BURNING CAN BE SMELLED WHEN EXITING THE VEHICLE.COSTS TO REPAIR ARE QUOTED AT $3296 PLUS TAXES.

CAM TOWER SEAL PROBLEMS CURRENTLY MY TUNDRA IS HAVING A CAMSHAFT TOWER SEALS PROBLEM/GASKET. I THOUGHT MY TRUCK WAS GOING TO CATCH ON FIRE SEVERAL TIMES WITH MY GRAND KIDS INSIDE WHILE DRIVING.'.WITH IT SMOKING ON THE PASSENGER SIDE. THIS IS HIGHLY UNUSUAL FOR A TOYOTA. I THOUGHT IT WOULD HAVE STOPPED BY NOW, BUT IT HAS NOT. THIS HAS BEEN AN ONGOING PROBLEM SINCE I PURCHASED THE TRUCK. IN DOING MY RESEARCH, WHICH I UNDERSTAND IS A BIG REPAIR JOB AS IT REQUIRES DISMANTLING PART OF THE ENGINE; THIS IS A MAJOR PROBLEM WITH THIS MODEL YEAR THAT I CURRENTLY OWN (2011). THERE ARE ALSO SEVERAL OTHER MODEL YEARS THAT IT IS ALSO HAPPENING AS WELL (2011-13), IN WHICH AGAIN CAN CAUSE THE TRUCK TO CATCH FIRE, HARMING OR EVEN KILLING SOMEONE. IF NOT COMPLETED NOW OR TAKE ANY ACTION, TOYOTA COULD LOSE MONEY. YOU COULD EVEN STOP LAWSUITS THAT WILL BE FORTHCOMING WITH THIS ISSUE IF SOMEONE IS HARMED OR EVEN KILLED. THIS IS VERY DANGEROUS!! THIS IS MY SIXTH TOYOTA PURCHASE. THE MAIN REASONS FOR ME CHOOSING TOYOTA OVER FORD, GM, ETC. ARE QUALITY AND RELIABILITY. I WOULD LIKE TOYOTA TO FIX MY ISSUE AT NO COST TO ME AND MAYBE RECALL THIS ERROR THAT TOYOTA SHOULD BE AWARE OF ON THESE MODEL TUNDRA TRUCKS. THIS HONEST GESTURE WOULD BOLSTER MY CONFIDENCE IN THE REASONS I MADE IN PURCHASING A TOYOTA.

I WAS DRIVING ON THE FREEWAY AND MY TUNDRA WOULD NOT GO PAST 20 MPH. I ALMOST GOT INTO AN ACCIDENT ON THE FREEWAY AND HAD TO PULL OFF/EXIT. I BROUGHT IT TO A TOYOTA DEALER FOR AN AUTHORIZE DIAGNOSTIC AND REPAIR. MY SECONDARY INJECTION VALVE WAS DEFECTIVE BACK IN JANUARY 2016 AND THE QUOTE PRICE WAS $2860 FROM MY LOCAL TOYOTA DEALER. TOYOTA DID NOT COVER THE FAULTY INJECTION UNTIL A WARRANTY ENHANCEMENT LETTER CAME OUT IN AUGUST 2017 FOR OWNER'S TO SUBMIT PAPERWORK. THIS MAY AFFECT OTHER TOYOTA TUNDRA AND SEQUOIA MODEL AS WELL.

WHILE DRIVING THE CHECK ENGINE LIGHT CAME ON AND I LOST PROPULSION POWER RESULTING IN VEHICLE SLOWING DOWN AND ALMOST CREATING AN ACCIDENT FROM BEHIND. I HAD THE VEHICLE CHECKED VIA A OBD2 CODE CHECKER WHICH RESULTED IN CODE P2442. AFTER VERIFYING CODE, IT LOOKS AS IF IT IS A FAULTY AIR INTAKE. LOOKING THROUGH SEVERAL SOURCES ON THE INTERNET, IT SEEMS TO BE A VERY COMMON PROBLEM THAT TOYOTA IS REFUSING TO ACKNOWLEDGE OR REPAIR. PLEASE TAKE THIS ISSUE INTO CONSIDERATION AND HELP THE CONSUMER. FUEL PROPULSION SYSTEM I PURCHASED MY 2011 TUNDRA QUARTER END 2011. IT HAS LESS THAN 100K MILES AND IS WELL MAINTAINED BY THE DEALER.

MY 2011 TOYOTA TUNDRA WHILE IT WAS BEING DRIVEN THE ENGINE LIGHT CAME ON. IT WAS DRIVEN TO A NEARBY O' REILLY'S FOR A CODE CHECK. THE CODE WAS P0418 WHICH IS THE AIR INDUCTION PUMP WHICH IS AN EMISSION'S CODE. THE TRUCK THEN WENT INTO A LIMP MODE WHILE DRIVING HOME ON A BUSY CITY STREET WHICH MEANT IT WOULD NOT ACCELERATE OVER 35 MPH. THIS IS A VERY DANGEROUS SITUATION NOT HAVING THE ABILITY TO GO ANY FASTER DUE TO AN EMISSION'S CODE PUTTING THE TRUCK INTO A LIMP MODE. AFTER RESEARCHING THIS PROBLEM I FOUND OUT THAT TOYOTA HAS EXTENDED THE WARRANTY FOR THIS AIR INJECTION PUMP FOR THE 2007-2010 TUNDRA MODELS. TOYOTA HAS REFUSED TO HELP COVER THE COST FOR THIS REPAIR EVEN THOUGH IT IS A KNOWN PROBLEM ON TUNDRAS. I READ THAT THE SAME FAULTY AIR PUMP WHICH ALLOWS MOISTURE TO ENTER IS STILL BEING USED IN MY 2011 TUNDRA MODEL. THIS IS A $2,200 REPAIR WHICH TOYOTA SHOULD COVER SINCE IT HAS OCCURRED TO THEIR EARLIER MODELS AND MINE AS WELL. NOT ONLY IS THIS A COSTLY REPAIR, BUT ALSO A VERY DANGEROUS SITUATION WHEN YOUR VEHICLE IS UNABLE TO ACCELERATE ON AN EMISSIONS PROBLEM.

VEHICLE WOULD NOT ACCELERATE PAST 40MPH. THIS OCCURRED SUDDENLY WHILE DRIVING. DEALERSHIP DETERMINED IT WAS AIR INJECTION PUMP FAILURE. AFTER DISCUSSION WITH MASTER MECHANIC AND A SERVICE MANAGER I FOUND THAT THIS PROBLEM WAS DIAGNOSED IT EARLIER MODELS UP TO AND INCLUDING 2010 TUNDRA WHERE TOYOTA TOOK CARE OF THE REPAIR . BUT THEY CONTINUED TO USE THIS PART UNTIL LATE 2011. MY TRUCK WAS DELIVERED IN FALL OF 2010 AND HAD THE OLDER STYLE PART. THEY CHANGED THE PART DESIGN AND NOW IT PREVENTS MOISTURE TO ENTER THE PUMP AND PREVENTS CORROSION WHICH CAUSED PUMP FAILURE. THE ORIGINAL PART HAD FLARED HEAD TUBING AND NO SEAL THE NEW DESIGN HAS A SEALED TUBE END. TOYOTA NEW THIS WOULD FAIL YET THEY DID NOT MAKE THE RECALL I HAVE REQUESTED A REIMBURSEMENT BUT THE HAVE SO FAR FAILED TO DO SO THIS COST ME OVER $2400 THIS EXPENSE SHOULD BE ENTIRELY ON TOYOTA

?ON 12/26/2014, I STARTED MY TUNDRA, PLACED IT INTO GEAR AFTER A 30 SECOND PAUSE AND PROCEEDED TO LITERALLY STAND ON MY BREAKS TO STOP THE VEHICLE FROM LURCHING FORWARD.

ON SUN. 10/11/14, I DROVE OUR TUNDRA ON THE HIGHWAY WHEN IT LOST POWER. THE ENGINE RACED AND RPMS INCREASED, BUT THE SPEED FELL AND NO ACCELERATION WAS POSSIBLE. ON A HILL, SPEED FELL TO ABOUT 15 MPH. I WAS ON MY WAY TO PICK UP MY HORSE AND TRAILER; IF I HAD BEEN TOWING THEM, IT WOULD HAVE BEEN CATASTROPHIC ESPECIALLY GIVEN THE HIGHWAY SPEED TRAFFIC. IT WAS STILL DANGEROUS EVEN WITHOUT THE TRAILER. I TURNED ON MY HAZARD LIGHTS AND LIMPED OFF. "CHECK ENGINE" LIT UP. TOOK TO DEALERSHIP THE NEXT DAY, WHO SAID CHECK ENGINE CODE WAS "P2445" FOR "SECONDARY AIR INJECTION SYSTEM WATER INTRUSION" REQUIRING REPLACEMENT OF THE AIR PUMP ASSEMBLY, AIR PUMP INLET, EMISSION VALVE SET, ETC. FOR $2600 BECAUSE WATER INVADED THE SYSTEM. THE SERVICE TECH SAID THAT THIS WAS NOT A KNOWN ISSUE, BUT MY INTERNET SEARCH SHOWED THAT TOYOTA ISSUED A 12-PAGE 2011 TECHNICAL SERVICE BULLETIN, STATING THAT "THE AIR PUMP ASSEMBLY INLET HAS BEEN UPDATED TO PREVENT WATER INTRUSION." TOYOTA HAS NEITHER RECALLED THE DEFECTIVE INLETS NOR NOTIFIED OWNERS. THE TSB SAYS ONLY TRUCKS UNDER THE 36,000/ 3 YEAR WARRANTY ARE COVERED. TUNDRAS ARE TOW VEHICLES AND IT IS FORESEEABLE HOW UNSAFE THIS IS. BECAUSE MY TRUCK WAS SOLD JUST OVER 3 YEARS AGO, THE LOCAL DEALERSHIP AT FIRST COULD NOT COVER IT. I CONTACTED TOYOTA HEADQUARTERS, WHO REFERRED ME BACK TO THE LOCAL SERVICE MANAGER, WHO THEN REACHED SOUTHEAST REGIONAL TOYOTA OFFICE, WHICH FINALLY AGREED TO COVER THE REPAIR. WHEN THIS AIR PUMP INLET FAILS, IT ALLOWS WATER TO ENTER THE AIR INJECTION SYSTEM AND THE SYSTEM TO THEN FAIL IN THE DANGEROUS WAY THAT OCCURRED IN MY CASE, RESULTING IN A SUDDEN LOSS OF POWER. I AM CONCERNED ABOUT THIS HAPPENING TO OTHERS AND THAT THE DEALERS SEEM UNAWARE OF THIS TSB AND THIS "KNOWN ISSUE."

ON THEIR 5.7 LITER ENGINE KNOCKS WHEN YOU FIRST TAKE OFF. SOUNDS LIKE EXCESSIVE PISTON SLAP FROM THE MOTOR BEING BORED OUT TO BIG DURING PRODUCTION. I HAVE CONTACTED A TOYOTA DEALER AND TOYOTA THEMSELVES AND WAS TOLD THIS IS NORMAL. WITH THIS EXCESSIVE CLEARANCE IT WILL CAUSE THE ENGINE TO HAVE A SHORTENED LIFE. THE WAY TO FIX IT IS TO REBUILD IT OR REPLACE THE MOTOR. *JS

TRUCK'S COMPUTER IS READING AN INCORRECT PERCEIVED ALCOHOL DENSITY. TRUCK HAS A FLEX FUEL ENGINE AND THE COMPUTER IS TELLING THE ENGINE THAT THERE IS ETHANOL IN THE FUEL SYSTEM WHILE THERE IS NOT. I HAVE NEVER RUN ETHANOL IN THE TRUCK YET THE COMPUTER IS READING THAT THERE IS A 30-50% ALCOHOL DENSITY IN THE FUEL. THE PROBLEMS THAT HAVE RESULTED FROM THIS ARE MISSING WHILE UNDER POWER AND POWER LOSS WHILE DRIVING. HAVE HAD MY TRUCK TO MULTIPLE DEALERS OVER 5 TIMES NOW. THE DEALERS HAVE CONTINUED TO RE-FLASH MY TRUCK'S ECU ONLY TO HAVE THE PROBLEM TO COME BACK BECAUSE THE ECU IS A LEARNING ECU. TOYOTA HAS RELEASED A FIX FOR 2012 AND 2013 MODELS BUT NOT FOR THE 2011 MODELS WHICH IS LEAVING ME STRANDED. I PULL A BOAT FREQUENTLY AND THE LOSS IN POWER HAS SIGNIFICANT NEGATIVE EFFECTS ON TOWING. THIS PROBLEM ALSO CAUSES THE ENGINE TO RUN LEAN RESULTING IN POORER FUEL MILEAGE AND INCREASED COSTS FOR ME. I'VE TALKED WITH PEOPLE AT TOYOTA CORPORATE AND THEY HAVE TOLD ME THAT THERE ARE NO PLANS TO RELEASE A FIX FOR THE 2011'S AND THAT THERE IS BASICALLY NOTHING THAT I CAN DO. SO NOW I'M STUCK WITH A TRUCK THAT IS READING THE FUEL WRONG AND CAUSING THE TRUCK TO RUN LEAN WHICH IS SURELY GRADUALLY DAMAGING THE ENGINE WHICH I'M SURE WILL RESULT IN LOTS OF REPAIRS AFTER THE TRUCK IS OUT OF WARRANTY. *TR
