2008 Toyota Tundra Engine

The contact owns a 2008 Toyota Tundra. The contact stated while driving 50 MPH, the vehicles stalled. The contact stated that the vehicle hesitated and failed to accelerate above 50 MPH. The check engine warning light was illuminated. The vehicle was able to restart, but the failure recurred. The vehicle was taken to the dealer where to be diagnosed. The dealer determined that the secondary air injection pump had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure and referred the contact to the NHSTA Hotline for assistance. The approximate failure mileage was 116,000. The VIN was not available.

The contact owns a 2008 Toyota Tundra. The contact stated while driving 20 MPH, the vehicle stalled. There were no warning lights illuminated. The contact called an independent mechanic, but no assistance was provided. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.

The truck has had three engine oil leaks since 4-20-22. The most recent is being repaired now. In each of these leaks, engine oil leaks out of the valve cover and or the cam tower and drips onto the exhaust. The burning oil can be smelled inside the truck cab. I am concerned it could cause a fire. The dealer has repaired the first two leaks and is working on the cam tower leak now (drivers side). I notified Toyota, they refused to fix the problem.

Truck goes into low power mode or "limp" and has difficulty accelerating. The check engine light is on, “VSC OFF” light blinks on and off, as well as the “slippery tire” sign stays on. Very dangerous if this happens when driving on an expressway as you can't drive over 45 mph in low power mode. This is a known issue with Air Injection Pumps and Air Switching Valves for Toyota Tundra trucks between 2007-2008. Toyota extended the factory warranty instead of offering a recall. Due to the factory warranty extension Toyota would not fix this problem until it manifested, and it usually doesn't manifest until after the extension of the factory warranty has expired.

I HAVE A 2008 TOYOTA TUNDRA. THE SECONDARY AIR PUMP FAILED ON MY VEHICLE. I TOOK IT TO THE DEALER AND WAS TOLD I WOULD BE $3500 TO REPAIR. THIS IS KNOWN PROBLEM WITH THE TUNDRA. I WAS TOLD BY THE DEALER THAT TOYOTA HAD EXTENDED THE WARRANTY FOR THIS BUT IT EXPIRED AFTER 10 YEARS OR 150,000, I HAVE 121,000. WHEN THE PUMP FAILS IT CAUSES THE VEHICAL TO GO INTO LIMP MODE. I RAN A ERRAND TODAY AND THE TRUCK RAN FINE. I WENT TO THE STORE AND RETURNED TO THE TRUCK. I STARTED IT AND THE THE VSC LIGHT AND CHECK ENGINE LIGHT CAME ON. AS I HEADED INTO TRAFFIC THE VEHICAL WOULD NOT ACCELERATE TO KEEP UP WITH THE TRAFFIC AND ALMOST GOT REARENDED. TOYOTA SHOULD OF HAD A RECALL ON THIS BECAUSE IT IS A SAFETY FEATURE AND COULD CAUSE A SERIOUS ACCIDENT. THIS AIR PUMP IS INSTALLED ON TUNDRAS AND OTHER MODELS. I BOUGHT THIS TRUCK NEW IN 2008 AND HAVE SERVICED IT ON THE MFG SCHEDULE. SINCE THIS WAS A KNOWN PROBLEM TOYOTA SHOULD HAVE REPLACED THE PUMPS DURING REGULAR MAINTENANCE INSTEAD OF NOT DOING NOTHING AND HOPE IT DOES NOT OCCUR. EVEN IF I REPLACE THE PUMPS WHAT SAYS IT WON'T HAPPEN AGAIN. I LOST CONFIDENCE IN MY TRUCK AND AM AFRAID IT MIGHT HAPPEN AGAIN.

CHECK ENGINE LIGHT CAME ON. CODES INDICATED FAILED SECONDARY AIR INTAKE VALVE. TOOK IT TO DEALER WHO SAID I WAS ONE DAY OUTSIDE OF EXTENDED WARRANTY. NO WARNING OF ANY CONSEQUENCES OF NOT IMMEDIATELY ADDRESSING. DRIVING HOME ON INTERSTATE TRUCK TRUCK SUDDENLY HAD SEVERAL WARNING LIGHTS START TO FLASH AND WOULD NOT ACCELLERATE ABOVE 35. I WAS TRAPPED IN SUBSTANTIAL TRUCK TRAFFIC WITH NOWHERE TO PULL OFF AND COULDN'T EVEN CLIMB HILLS WITHOUT POWER DECREASING FURTHER. FOUND OUT THIS INTENTIONAL. TRUCK WAS PUT IN "LIMP" MODE BY PROGRAMMING. TO RESTRICT SPEED AND ACCELLERATION WITHOUT WARNING FOR A NONESSENTIAL FAULT WHICH IS NOT A THREAT TO ENGINE OPERATION IS INSANE.

SECONDARY AIR INJECTION SYSTEM HAS FAILED 3 TIMES PUMPS AND VAULVES, REPAIRED 2 TIMES I CAN'T AFFORED TO FIX IT A THIRD! THIS SHOULD BE A RECALL, THE DEALERSHIP SAID IT IS HAPPENING A LOT! $3000 IN REPAIRS! RUNS ON HALF POWER!

TL* THE CONTACT OWNS A 2008 TOYOTA TUNDRA. WHILE DRIVING VARIOUS SPEEDS, THE ENGINE WARNING INDICATOR ILLUMINATED. THE VEHICLE WAS TAKEN TO ATKINSON TOYOTA SOUTH DALLAS (LOCATED AT 39660 LYNDON B JOHNSON FWY, DALLAS, TX 75237, (972) 780-1166) WHERE IT WAS DIAGNOSED THAT THE AIR VALVE AND THE AIR INDUCTION PUMP NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND INFORMED THE CONTACT THAT THE WARRANTY ON THE VEHICLE WAS EXPIRED. THE MANUFACTURER OPENED CASE NUMBER: 1809192901. THE APPROXIMATE FAILURE MILEAGE WAS 107,404.

CODE P2442 CAME UP ON MY TRUCK. THIS CODE INDICATES THE SECONDARY AIR INJECTION PUMPS AND VALVES ARE GOING BAD ON MY TRUCK. ALSO CAUSES THE TRUCK TO GO INTO LIMP MODE RESULTING IN SEVERE LOSS OF POWER WHICH CAN BE DANGEROUS IN THE WRONG SITUATION. MY RESEARCH INDICATES THIS IS A KNOWN PROBLEM AND VERY EXPENSIVE TO FIX. TOYOTA WILL NOT FIX THE PROBLEM IF YOUR TRUCK HAS OVER 150000MI OR 10 YEARS SINCE FIRST USE. THIS AFFECTS ALL TUNDRA AND IS A KNOWN PROBLEM. TOYOTA HAS EXTENDED THE WARRANTY ON THIS ISSUE TWICE, SO THEY KNOW THIS SYSTEM IS DEFECTIVE. I BELIEVE THERE SHOULD BE A RECALL ON THE AFFECTED VEHICLES.

SOUNDS LIKE A DIESEL WHEN I START THEN GOES AWAY. NOW AT 55 MPH ANTI SLIP LIGHT FLASHES, WHILE IT FLASHED I LOSE ENGINE POWER UNTIL I LET OFF GAS SOON AS I LET OFF GAS POWER COMES BACK FOR A FEW SECONDS AND IT REPEATS UNTIL I TRAVEL AT LOWER SPEED TOOK TO DEALER NO CODES. HAPPEN AFTER I LEFT AND GOT UP TO ABOUT 60MPG

2008 TUNDRA MAKES A CLUNK/THUMP NOISE WHEN STOPPED AT SIGN/LIGHT AND SLOWLY ACCELERATING. NOT CAUSED BY NORMAL WEAR AND TEAR. CAUSED BY OTHER ISSUES THAT NEEDS TO BE INVESTIGATED BY TOYOTA. ISSUES STARTED AT 110,000 MILES. TOYOTA PLEASE HELP AS THIS IS NOT CAUSED BY THE CONSUMERS.

THE CHECK ENGINE CAME ON AND AN ENGINE CODE OF P2440 WAS READ. P2440 INDICATED THAT THE SECONDARY AIR INJECTION SYSTEM SWITCHING VALVE BANK 1 WAS STUCK OPEN. VEHICLE HAS NOT BEEN REPAIRED DUE TO THE HIGH COST OF THIS REPAIR.

CODE 2440. CONTROL VALVE STUCK IN AIR INJECTION PUMP. FAILED FOR THE 2ND TIME UPON STARTUP. FIRST FAILED AT 68K MILES EARLY 2013. TOYOTA REPLACED IT FOR FREE. THEY'VE HAD SO MANY FAIL THAT THEY EXTENDED THE WARRANTY TO 10 YR, 150K MILES. THEN IT JUST FAILED AGAIN AT 154K MILES. THEY WON'T WARRANTY THE 2ND ONE BECAUSE IT'S 4K MILES OUT. EVEN THOUGH THE PART ONLY HAS 86K MILES ON IT. COST IS $2100 FROM THE DEALER! 1200 OF THAT IS JUST THE PARTS. FROM WHAT I'VE READ THIS PART IS ONLY REQUIRED FOR THE FIRST COUPLE MINUTES OF OPERATION ON A COLD START. IT PREHEATS THE CATALYTIC CONVERTER SO IT WORKS BETTER. THE EPA SHOULD BE EXEMPTING MINOR DISCREPENCIES IN THEIR EMISSIONS LAWS WHILE WORKING WITH MANUFACTURERS TO DEVELOP SENSIBLE SOLUTIONS. IN THE MEANTIME WE GET STUCK WITH COMPANIES THAT DO A SHODDY JOB DESIGNING THE SYSTEM, PLACE IT IN A TERRIBLE LOCATION REQUIRING MANY HOURS TO DO THE REPLACEMENT, AND THEN ARE BOUND BY LAW (IN MY STATE) TO MAINTAIN THE EQUIPMENT. THE TRUCK IS IN LIMP MODE AND IS DANGEROUS TO DRIVE.....GUESS I HAVE TO SHELL OUT THE CASH. AFTER READING HUNDREDS OF COMPLAINTS ON MULTIPLE TRUCK FORUMS AND EXPERIENCING THE PART TO FAIL TWICE FIRSTHAND, IT'S OBVIOUS THIS IS NOT AN UNCOMMON PROBLEM. THE CSR FROM TOYOTA ACTED LIKE THEY DID ME A FAVOR BY "VOLUNTARILY" EXTENDING THE WARRANTY TO 150K MILES. NO COMPANY "VOLUNTARILY" DOES THIS. I WOULD LIKE FOR YOU TO CONSIDER HAVING THEM ISSUE A PROPER RECALL, EXEMPTING THE AFFECTED MAKE/MODEL YEARS FROM EMISSIONS STANDARDS FOR A FAILED SYSTEM WHICH WOULD ALLOW OWNERS TO BYPASS THE SYSTEM LEGALLY FOR ABOUT $150 IN PARTS (HARNESS & VALVE PORT BLOCKING PLATES), OR PRESSURING TOYOTA TO EXTEND WARRANTY COVERAGE TO THE PART (NOT THE TRUCK) IF IT FAILS IN THE SAME WAY. A $2000+ FIX ON A NON-ESSENTIAL COMPONENT SHOULD NOT BE A 75K MILE RECURRING COST.

2008 TOYOTA TUNDRA TRUCK WITH 5.7L ENGINE. VEHICLE HAS A LOUD KNOCKING NOISE THAT SEEMS TO BE A VALVE TRAIN NOISE WHEN TRUCK IS ACCELERATING AFTER SLOWING DOWN, UNDER LOAD OR TOWING A TRAILER. TOOK TRUCK TO THE DEALER MULTIPLE TIMES SO FAR , WITH FEEDBACK RANGING FROM CAN'T HEAR ANYTHING TO THIS IS A NORMAL NOISE OF THE ENGINE. I HAVE READ MANY POSTINGS ONLINE ABOUT THIS ISSUE BUT DEALER DOES NOT RECOGNIZE THE PROBLEM AND INSISTS CONDITION IS NORMAL. THIS SEEMS TO BE A POOR DESIGN OR POOR QUALITY THAT TOYOTA NEEDS TO ADDRESS. I OWN SEVERAL TOYOTAS AND IT SEEMS QUALITY STANDARDS ARE REALLY DROPPING LATELY. PERHAPS IT IS TIME TO MOVE AWAY FROM TOYOTA BRAND. THIS ENGINE SITUATION COULD BE VERY DANGEROUS ISSUE IF A PART INSIDE OF THE ENGINE BREAKS OFF AND CAUSE THE ENGINE TO SHUT DOWN, LEADING TO LOSS OF BRAKING AND STEERING CAPABILITIES. *TR

THE BRACKET THAT HOLDS THE FAN PULLEY CATASTROPHICALLY FAILED AND BROKE AWAY FROM THE VEHICLE, CAUSE THE SERPENTINE BELT TO GIVE, CAUSING THE TRUCK TO LOOSE POWER STEERING AND CRASH INTO A ROAD SIDE DITCH. THIS TRUCK HAD PARTS REPLACED 6 MONTHS BEFORE THE FAILURE, AND NO PROBLEMS WERE REPORTED TO OWNER. *TR

ERROR CODES P2240,P2241. SOMETHING TO DO WITH THE EMISSIONS. *TR

WHEN STARTING THE TOYOTA TUNDRA THE 4LO , VSR, CHECK ENGINE , LIGHTS LIT UP AND THE VEHICLE HAD NO POWER IT WOULD 'NT RUN HAD TO TAKE THE BATTERY CABLE OFF TO RESET COMPUTER, IT CLEARED THE SYSTEM THEN THE SAME THING HAPPEN A WEEK LATER TOOK IT IN TO THE TOYOTA SERVICE SHOP AND THEY COULDN'T FIND ANYTHING WRONG WITH IT. I AM STILL HAVING THE SAME PROBLEM WITH THE TRUCK ALMOST EVERY OTHER DAY CALLED TOYOTA CUSTOMER CARE AND THEY TOLD ME THAT'S ITS NOT COVERED UNDER A RECALL . I FOUND OUT THE PROBLEM IS THE SECONDARY AIR PUMPS AND INJECTION SYSTEM AND HAVE ALSO READ THAT A LOT OF PEOPLE ARE HAVING THE SAME PROBLEM. *TR

EMISSIONS VALVE AND RELATED PUMPS FAILED CAUSING A SIGNIFICANT LOSS IN POWER. THIS HAPPENED WHEN TRAVELING ON THE HIGHWAY IN UPSTATE VERMONT. SUDDENLY MY TRUCK LOST SIGNIFICANT POWER, AND WOULD RAPIDLY DECELARATE EVERYTIME I APPROACH A POSITIVE GRADE IN THE ROAD. SEVERAL TIMES DURING THE TRIP I SLOWED DOWN FASTER THAN CARS BEHIND ME EXPECTED, AND THE BRAKE LIGHTS DID NOT WARN THEM AS IT WAS DUE TO THE TRUCK LOSING POWER, AND NOT ME BRAKING. IN ADDITION DUE TO THE LOCATION I WAS AT I WAS UNABLE TO LOCATE A DEALER FOR SEVERAL MILES. WHEN THE CODES WERE PULLED FOR THE SERVICE ENGINE IT APPEARED AS CODE P2442 (SECONDARY AIR INJECTION PUMP SYSTEM SWITCHING CALVE STUCK OPEN BNKS) *KB

TRUCK WENT INTO "LIMP" MODE AND THE VSC, CHECK ENGINE LIGHT AND THE "TRACTION" LIGHT ALL CAME ON. TOOK IT TO AUTOZONE TO GET A READ OUT AND IT HAD A P2442 FOR A SUBARU, BUT WAS FIGURED TO BE THE ASV (AIR SWITCH VALVE) OR THE AIP (AIR INDUCTION PUMP) ON BANK 2. CONSIDERING THAT MY TRUCK IS OUT OF WARRANTY WITH 62000 MILES AND ALL THE FORUM AND WEBSITES THAT I HAVE BEEN TO THAT TOLD ME IT WOULD CAST ANY WHERE FROM 1000 TO 5000 BUCKS TO FIX, I CHECKED IT OUT MYSELF. THE ASV ON THE DRIVER SIDE HAS A METAL PLATE THAT IS BROKEN AND IS KEEPING THE VALVE OPENED. I HAVE CALLED A DEALER AND THEY TOLD ME THEY HAVE NO CLUE WHEN THE PARTS COULD BE IN BECAUSE OF THE TSUNAMI IN JAPAN. I AM VERY UPSET AS TO THIS ISSUE AS I AM NOT ABLE TO BYPASS THE IT AND GET MY TRUCK RUNNING CORRECTLY. TOYOTA NEEDS TO STEP UP AND MAKE A RECALL ON THESE PUMPS AND VALVES. I WAS TOLD THAT ONE OF THE REASONS FOR THE ISSUES IS THAT WATER GETS IN THE PIMPS. I CANNOT SEE HOW WATER IS GETTING IN THESE PUMPS AND VALVES AS THEY ARE ENCLOSED. THIS IS A DESIGN FLAW AND NEEDS TO BE RECTIFIED. *TR

TL*THE CONTACT OWNS A 2008 TOYOTA TUNDRA. WHILE DRIVING APPROXIMATELY 70 MPH THE CONTACT STATED THAT THE VEHICLE SHIFTED INTO LIMP MODE.

ON FEBRUARY 12, 2011 THE FAILURE RECURRED, AND THE VEHICLE WAS TAKEN TO A SECOND DEALER. THE DEALER ADVISED HIM THAT TWO AIR INJECTION SWITCH VALVES AND TWO AIR PUMPS NEEDED TO BE REPLACED. THE VEHICLE WAS IN THE DEALERS POSSESSION WHEN THE COMPLAINT ALTHOUGH THE CONTACT HAD AUTHORIZED THE REPAIR. THE VIN WAS UNAVAILABLE. THE FAILURE MILEAGE WAS 135,000 AND THE CURRENT MILEAGE WAS 180,000.
