2008 TOYOTA TUNDRA Engine And Engine Cooling Problems

MY 2008 TUNDRA SUDDENLY SHOWED MULTIPLE DASH LIGHTS WHEN I STARTED IT. IT RAN ROUGH, TRIED CODE READER ON IT ,AGAIN MULTIPLE CODES AT ONCE. EVERY ITEM CAN'T BAD ALL AT SAME TIME. THE MAIN PROBLEM WAS AIR PUMP FAILURE, HAVE A FEELING IT'S ASSOCIATED WITH EXHAUST PROBLEM. TRUCK HAS BEEN TICKING SINCE ABOUT A MONTH AFTER I BOUGHT IT BRAND NEW, I JUST ASSUMED THAT'S THE WAY IT WAS SINCE IT QUIETS AFTER WARMS UP. TURNS OUT MANIFOLD IS CRACKED BY THE PUMP. OF COURSE WARRANTY IS UP. AFTER READING ONLINE SEEMS LIKE A LOT OF PEOPLE ARE HAVING SAME PROBLEM. HAVE HAD IT SEVERAL TIMES OVER THE YEARS FOR OIL CHANGES ETC. . THE DEALERSHIP'S KNOW THERE IS A PROBLEM AND IGNORE THEM. I HAVE TWO OTHER TOYOTA CARS AND THIS IS THE FIRST TOYOTA TRUCK I'VE BOUGHT . TOYOTA WE'LL HAVE A BIGGER PROBLEM WHEN GO BACK...

I WAS DRIVING DOWN THE ROAD AND THE TRUCK STARTED TO MAKE A LOUD CLICKING NOISE. I WAS ONLY A FEW BLOCKS FROM MY HOUSE. I WENT HOME, THE TRUCK WOULDN'T START AGAIN.MY 2008 TOYOTA TUNDRA HAD AN "ENGINE FAILURE" AT 62000 MILES. FIRST THEY SAID $23,000 FOR A NEW ENGINE. THEN AFTER MONTHS AND MANY HOURS ON THE PHONE, THEY TOOK THE ENGINE APART TO FIND THE PROBLEM. THE DEALER TOOK PICTURES AND SENT THEM TO TOYOTA. THEY SAID A VALVE OR VALVE SPRING FELL THROUGH AND TORE EVERYTHING UP. IT NEEDED A NEW SHORT BLOCK AND RIGHT HEAD ($14,000). TOYOTA ADMITTED 100% FAULT AND SAID BECAUSE THE VEHICLE IS 2000 MILES OUT OF WARRANTY THEY WILL COVER ONLY 50% UNDER " GOODWILL ASSISTANCE" . SO I BOUGHT THE MOTOR TREND TRUCK OF THE YEAR ( BRAND NEW) AND HAD TO TAKE OUT A LOAN FOR $7000 TO GET...

MY TRUCK WAS PARKED FOR 3 DAYS, THEN WHEN I STARTED THE ENGINE ALL OF THE TRACTION CONTROL LIGHTS STARTED FLASHING, THE CHECK ENGINE LIGHT REMAINED ON STEADY, AND 4LO LIGHT FLASHED, TRUCK WOULD NOT TRAVEL OVER 30 MPH AND BECAME VERY SLUGGISH. THIS HAS HAPPENED THREE TIMES IN ONE WEEK, AND DISCONNECTING BATTERY FOR A FEW MINUTES CLEARED THE PROBLEM. LOCAL DEALERSHIP SAID THE PROBLEM IS A "FAILED ACTUATOR ECU ASSEMBLY FAILED COMMUNICATION C1201". COST OF REPAIR IS $2,280.41. WARRANTY DOES NOT COVER REPAIR BECAUSE THIS PART IS ONLY COVERED BY THE 3 YEAR/36000 MILE WARRANTY. DRIVETRAIN WARRANTY DOES NOT COVER THIS COMPONENT. THIS IS A SAFETY CONCERN BECAUSE WHEN THIS PROBLEM OCCURS WHILE DRIVING THERE IS NO WARNING AND COULD RESULT IN A MULTIPLE VEHICLE ACCIDENT. THE ONLY OTHER PART THAT CAUSES THIS PROBLEM IS AN AIR PUMP ASSEMBLY WHICH IS NOW REQUIRED TO BE COVERED BY TOYOTA...

ENGINE TURNS OFF GOING DOWN THE ROAD AND THEN STARTS UP AT FULL THROTTLE. ALL THE LIGHTS ARE FLASHING ON THE DASH INCLUDING THE 4 LO LIGHT. I HAVE BEEN DEALING WITH THIS ISSUE SINCE THE TRUCK HAD 10K ON IT AND NOW IT HAS 42K ON IT. *TR

THE ENGINE CHECK LIGHT CAME ON AND THE ENGINE WENT INTO LIMP MODE, WHICH REDUCES ENGINE POWER MAKING IT DANGEROUS TO DRIVE. THE CHECK ENGINE LIGHT CAME ON FROM THE EMISSIONS VALVE SET FAILING. WHEN REPAIRED BY DEALER THEY ALSO DISCOVERED A CRACKED MANIFOLD. THIS EMISSIONS VALVE SET FAILURE SEEMS TO BE VERY COMMON ON 2008 TUNDRAS AND IS VERY EXPENSIVE TO REPAIR. TO MY SURPRISE THE MANIFOLD WAS CRACKED AND THAT IS A VERY EXPENSIVE REPAIR AND MAY HAVE CONTRIBUTED TO THE EMISSIONS VALVE SET FAILURE. TOYOTA SHOULD RECALL THEIR EMISSIONS VALVE SET AND REDESIGN IT SO IT DOES NOT FAIL, AND IS LESS EXPENSIVE TO REPLACE, AND FINALLY THEY SHOULD NOT PROGRAM THE ENGINE TO GO INTO LIMP MODE IF THIS FAILURE OCCURS, AS IT CAN CAUSE YOU TO LOSE POWER WHILE DRIVING IN VARIOUS CONDITIONS THAT REQUIRE POWER TO GET OFF THE ROAD SAFELY.

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...
