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.

The air injection pumps went out. Vehicle could not get out of limp mode, was very dangerous as I couldnt get up to speed while merging onto traffic. Had to put hazards on and drive vehicle home under 25mph. Vehicles were going around me. Vehicle is scheduled to be looked at by a dealer, but still recommend this be a safety issue!!

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.

TUNDRA WON'T ACCELERATE AS ENGINE GOES INTO LIMP MODE WHICH RESTRICTS SPEED CAPABILITY OF VEHICLE. THIS IS RELATED TO AIR INJECTION PUMP FAILURE AND RELATED ALSO TO AIR SWITCHING VALVES. LIMP MODE ON A TOYOTA RESTRICTS SPEED AT WHICH YOU CAN DRIVE, SHIFTING AND TOP SPEED ARE RESTRICTED. SLOWS TO POINT IF ENTERING HIGHWAY OR TRYING TO KEEP UP WITH SPEED OVER 50 MPH COULD NOT DO IT. TOYOTA IS AWARE AND HAS A CUSTOMER SUPPORT PROGRAM ZTQ BUYING VEHICLE USED NOT AWARE OF THIS OR ANYTHING ABOUT IT. I SLOWED TRAFFIC AND CAUSED BACK UP ON THE STREET WAS TRAVELING COULD NIT DO MORE THAN 20-30 MPH ON ROAD POSTED AT 50 MPH. GLAD NOT ENTERING FREEWAY. PLENTY OF U TUBE VIDEOS DETAILING REPAIR AND PROBLEM. THE TOYOTA DOCUMENTATION SAYS 477,000 TUNDRA VEHICLES WERE COVERED BY THIS ENHANCED WARRANTY PROGRAM. PREVIOUS OWNER DID COMPLAIN TO TOYOTA AND HAD COMPUTER REPLACED ON VEHICLE.

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.

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.

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.
