2011 Toyota Tundra Engine Problems

Your check engine light came on while driving. The dealer diagnosed water getting into your fuel injection system, which caused error codes. There's a recall for this issue, but your truck exceeded the mileage limit for coverage. Even after the dealer repaired it, the problem came back. The repair will likely involve inspecting and replacing fuel injectors and sealing any water intrusion points in the fuel system.

Your truck's secondary air injection system is stuck in a closed position, causing it to enter "limp" mode where you can only drive 35 mph. This prevents your exhaust from being properly diluted, and harmful fumes may enter the cabin. The check engine light (code P2441) came on around July 24th and symptoms worsened over time. While Toyota issued extended warranties for 2007-2010 Tundras with this design flaw, your 2011 model—which shares the same generation and the same defective design—is not covered. The repair will likely involve replacing the air injection pump and valve assembly.

During a routine inspection of your 2011 Toyota Tundra, mechanics found engine oil on the heat shield. The dealer diagnosed a leaking cam tower (on the passenger side) as the source, which needs replacement. This happened at approximately 32,000 miles.

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.

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.

VALVE SPRING FAILURE

VALVE SPRING FAILURE AT 136,124 MILES WHILE DRIVING TO WORK. TRUCK RAN FINE, NO PROBLEMS BEFORE THIS, EXTENDED WARRANTY EXPIRED END OF LAST YEAR. STILL FINANCED AND OWE OVER 13,000 FOR TRUCK. MOTOR RUINED .

MY TRUCK IS SMOKING WHILE DRIVING AS IF TO CATCH ON FIRE FROM THE CAM TOWER SEALS LEAKING . THIS HAS HAPPENED SEVERAL TIMES AND THE LAST TIME IT HAPPENED WAS JANUARY 14 2018.THIS IS A SAFETY HAZARD AND FIRE HAZARD. I HAD MY GRAND KIDS IN THE TRUCK AT THE TIME, ONE HAS LUEKEMIA. I DON'T WANT IT TO BURN US ALL UP IN THE TRUCK. CAM TOWER SEAL WAS LEAKING FROM BOTH SIDES. THEY ALSO FOUND VALVE COVER WAS LEAKING AS WELL. THIS WAS A GREAT SAFETY CONCERN DUE TO FIRE HAZARD. FACTORY DEFECT DUE TO INSUFFICIENT SEAL APPLIED TO THE MATTING SURFACES. DEFECT NEED TO BE TAKEN CARE OF PLEASE.

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.

ENGINE OIL LEAKED FROM VALVE COVER AREA ONTO EXHAUST HEAT SHIELD WITHIN 17K MILES OF OWNER SHIP. THIS OIL LEAK IS KNOWN AS THE TUNDRA CAM TOWER LEAK AND SPANNED MODEL YEARS 2010 TO ABOUT 2015. HERE'S A LINK TO A FORUM DISCUSSING IT: HTTP://WWW.TUNDRATALK.NET/FORUMS/TUNDRA-PROBLEMS-MAINTENANCE-REPAIR-DEALER-WARRANTY-ISSUES/140601-CAM-TOWER-OIL-LEAK.HTML ALSO A GOOGLE SEARCH WILL LIST MANY MORE COMPLAINTS. THE DEGREE OF THE PROBLEM VARIES, FROM SEEPING TO A LEAK WHERE OIL LEAKS ONTO THE EXHAUST HEAT SHIELD AS WAS THE CASE FOR ME. THE VEHICLE WAS REPAIRED AND TOYOTA DID PROVIDE ME WITH AN EXTENDED WARRANTY TO ADDRESS MY CONCERNS ABOUT VEHICLE RELIABILITY. ATTACHED IS A PHOTO, AND PHOTOS OF THE REPAIR RECEIPT WITH PRIVACY INFORMATION REMOVED. THE LAST THREE DIGITS OF THE VIN ARE VISIBLE ON THE RECEIPT SO IT CAN BE MATCHED TO THE VIN OF VEHICLE.

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. LATE MAY 2017 E LIGHT CAME ON AND I TOOK THE VEHICLE TO THE DEALER TO HAVE THIS CHECKED. I LEARNED THAT I HAD AN ISSUE WITH THE SECONDARY AIR INJECTION SYSTEM. THE ESTIMATED COST OF THE REPAIR WAS QUOTED AT $3,000

THE MANUFACTURER WAS MADE AWARE OF THE FAILURE AND OFFERED TO PROVIDE A PORTION OF THE REPAIR COST. THE VIN WAS UNKNOWN. THE APPROXIMATE FAILURE MILEAGE WAS 102,000. UPDATED 06/08/17*LJ *AS

MY CAR HAS ONLY 31914 MILEAGE AND I NEED TO REPLACE "AIR PUMPS KIT" . I WENT TO ONE OF THE DEALERS TOYOTA IN SOUTHFLORIDA NAMED; "HEADQUARTER TOYOTA" AND THEY CHARGED ME $3116.63 FOR THIS REPLACEMENT.

TL* THE CONTACT OWNS A 2011 TOYOTA TUNDRA. WHILE DRIVING VARIOUS SPEEDS, THE VEHICLE WOULD SUDDENLY GO INTO LIMP MODE, THE CHECK ENGINE SENSOR INDICATOR ILLUMINATED AND THE VEHICLE REDUCED SPEED AND WOULD NOT ACCELERATE PAST 30 MPH. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE SECONDARY EGR VALVES WERE FAULTY DUE TO CORROSION AND MOISTURE AND NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED, BUT THE FAILURE RECURRED APPROXIMATELY ONE YEAR LATER. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 40,000. UPDATED 10/13/16*LJ

CONSUMING 1 QUART OF OIL EVERY 1K MILES IS UNACCEPTABLE! MY ENGINE AT THE TIME I DISCOVERED THIS ONLY HAD 50K MILES ON IT. IF I WAIT UNTIL MY NEXT SCHEDULED OIL CHANGE (5K-10K) MY ENGINE WILL FAIL DUE TO LOW LEVEL OF OIL LEFT, IF ANY.

SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE STUCK OPEN BANK 2. EXPERIENCED P2442 CODE AND VSC ILLUMINATED ON DASH. TRUCK WAS STARTED ON A NORMAL MORNING WHEN PROBLEM AROSE. CURRENT MILEAGE ON TRUCK IS 64,277. WARRANTY FOR AIR INJECTION PUMP SYSTEM NEEDS TO BE EXTENDED TO NEWER MODEL TUNDRAS. THERE IS A CURRENT WARRANTY ON 2007-2010 MODEL TUNDRAS

TL* THE CONTACT OWNS A 2011 TOYOTA TUNDRA. WHILE DRIVING AT 60 MPH, THE VEHICLE DECELERATED AND THE ENGINE AND SLIP DIFFERENTIAL LIGHTS ILLUMINATED.

THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 90,000.

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

TL* THE CONTACT OWNS A 2011 TOYOTA TUNDRA. THE CONTACT STATED WHILE DRIVING AT VARIOUS SPEEDS THE VEHICLE DECELERATED TO 25 MPH AND DID NOT REGAIN ACCELERATION. THE FAILURE WAS EXPERIENCED NUMEROUS TIMES. THE VEHICLE WAS TAKEN TO THE DEALERSHIP A DIAGNOSTIC WAS PERFORMED WHICH LOCATED THE FAILURE AT THE SECONDARY AIR PUMP SYSTEM. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 50,000. UPDATED 9/4/14*CN

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
