2001 Toyota Tundra engine problems

ENGINE AND ENGINE COOLING

THE TOYOTA SAFETY RECALL WORK DONE IN 2012 TO TREATED MY VEHICLES FRAME TO PREVENT RUST PERFORATION HAS FAILED. DURING NH STATE INSPECTION AREAS WHERE THE FRAME HAD RUSTED THROUGH WERE IDENTIFIED. THESE AREAS HAD BEEN TREATED UNDER TOYOTA'S GUIDANCE AND AT THEIR EXPENSE. DUE TO FRAME RUST PERFORATION, AND RUST ISSUES IDENTIFIED BELOW MY VEHICLE WOULD NOT PASS INSPECTION. TOYOTA OF PORTSMOUTH, WHERE THE INITIAL RECALL WORK WAS INITIATED, AND TOYOTA MOTOR SALES HAVE BOTH DENIED TO REMEDY THIS SITUATION. MANY OTHER 2001 TOYOTA TUNDRA OWNERS WERE PROVIDED COMPLETE FRAME REPLACEMENTS. I WAS PROVIDED WITH A RUST TREATMENT THAT HAS FAILED TO CORRECT THIS SAFETY ISSUE. THE STATE INSPECTION WAS REQUESTED BY ME PRIOR TO SPENDING $2,776 (AND UP TO $5,000 OR MORE IF INTERNAL PARTS WERE DAMAGED) TO REPLACE A RUSTED THROUGH AND LEAKING REAR DIFFERENTIAL CASE THAT COULD HAVE SEIZED UP AT HIGHWAY SPEEDS IF I HAD NOT NOTICED THE LEAK. THIS INSPECTION ALSO IDENTIFIED FOR THE SECOND TIME A RUSTED THROUGH AND LEAKING EXHAUST MANIFOLDS (THE LEFT MANIFOLD WAS "STARTING" TO LEAK ON 09/16/2014 WHEN THE TRUCK LAST PASSED INSPECTION. I HEARD THE TICKING SOUND, CHARACTERISTIC OF THIS LEAK, SINCE THE VEHICLE WAS UNDER WARRANTY AND TOLD IT WAS NORMAL. THE BODY AND BED OF MY TRUCK WAS DETERMINED BY A LOCAL BODY SHOP TO BE IN GOOD CONDITION WITH MINIMAL RUST. THIS WAS DETERMINED BY VISUAL INSPECTION AND THE CONDITION OF THE LOWER PORTIONS OF THE DOORS WHICH ARE FREQUENTLY A TROUBLE SPOT IN STATES WHERE ROAD SALT IS USED AND THE FIRST LOCATIONS WHERE RUST (BODY ROT) APPEARS. TOYOTA HAS FAILED TO PROVIDE ADEQUATE CORROSION PROTECTION ON THE FRAME AND REAR DIFFERENTIAL OF MY TRUCK AND CREATED SERIOUS SAFETY ISSUES. THE FRAME RUST TREATMENT TOYOTA USED ON MY TRUCK DID NOT WORK. I DO NOT UNDERSTAND WHY THEY HAVE DECLINED TO REMEDY THIS SITUATION. THEY HAVE REPLACED MANY FRAMES FOR OTHERS.

ENGINE AND ENGINE COOLING

NOTICED OIL IN DRIVE WAY LOOKED UNDER TRUCK AND NOTICE MY STEERING RACK WAS LEAKING AND STABILIZER LINKS WERE RUSTED OFF. TOOK TO MECHANIC FOR REPAIRS AND HE INFORMED ME MY WHOLE EXHAUST WAS RUSTED AS WELL AS THE BODY. TOOK TO A TOYOTA DEALERSHIP BACK IN 2009 FOR BODY RUST RECALL AND WAS TOLD IT WAS OK. I NOW NO THAT WAS NOT TRUE.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM

2001 TOYOTA TUNDRA LIMITED V8 4X4, CURRENTLY AT 39,400 MILES. AT APPROXIMATELY 33,000 MILES - 2 YEARS AGO - I TOOK THE TRUCK INTO THE DEALERSHIP FOR A LOUD KNOCKING AT COLD START-UP. THEY WERE "UNABLE" TO REPRODUCE THE PROBLEM EVEN AFTER LEAVING THE VEHICLE FOR TWO DAYS. THE NEXT VISIT FOR SERVICE, I HAD CRACKED EXHAUST MANIFOLDS, BUT WAS TOLD I WAS OUT OF WARRANTY AND IT WOULD BE ABOUT $1700 PER MANIFOLD TO REPLACE THESE. I PURCHASED QUALITY AFTERMARKET MANIFOLDS AND HAD THEM INSTALLED BY AN INDEPENDENT SHOP FOR LESS THAN $1,200 FOR BOTH SIDES. I NOW SEE WHERE MANY, MANY OTHERS HAVE HAD THIS SAME EXPERIENCE AND BELIEVE THE ORIGINAL MANIFOLDS TO BE FAULTY. TOYOTA NEEDS TO EITHER MAKE THE REPAIRS UNDER WARRANTY, OR REIMBURSE THOSE OF US WHO PAID OUT OF POCKET FOR REPLACING DEFECTIVE, POORLY MADE MANIFOLDS.

ENGINE AND ENGINE COOLING

I TOOK MY 2001 TOYOTA TUNDRA TO THE MECHANIC BECAUSE THE EXHAUST SYSTEM WAS GETTING NOISY. WHEN THE MECHANIC HAD THE CAR JACKED UP, HE NOTED THAT THE FRAME WAS EXTREMELY RUSTY ON THE DRIVER'S SIDE IN FRONT OF THE BACK TIRE. IT WAS ACTUALLY ALMOST RUSTED THROUGH. HE SAID IT LOOKED LIKE IT COULD BREAK AT ANY MINUTE AND GOT AWAY FROM THE VEHICLE. I CONTACTED THE DEALER WHERE WE PURCHASED THE TRUCK WHO SAID I SHOULD DRIVE IT DOWN FOR THEM TO INSPECT IT. I REFUSED BECAUSE OF THE SAFETY ISSUE NOTHING HAS BEEN DONE AT THIS POINT AND THE TRUCK IS STILL AT THE MECHANICS.

2001 TOYOTA TUNDRA 32,500 MILES, BOTH EXHAUST MANIFOLDS ARE CRACKED, THE DEALER STATES THAT THE CAR IS OUT OF WARR. AFTER A MONTH OF BACK AND FORTH WITH TOY. MAIN OFFICE. THEY TELL ME THEY WILL PAY LABOR AND 1/2 PART,I PAY THE REST ($350). THIS IS A DESIGN PROBLEM EXHAUST MANIFOLDS DON'T CRACK, THIS PROBLEM IS THE FIST LINE IN THE MSN REVIEW OF THIS CAR & ALL OVER THE WEB. WHAT DOES IT TAKE TO GET "SATISFACTION & RELIABILITY" FROM TOYOTA JUST ADMIT THERE'S A DESIGN PROBLEM AND FIX IT..

VEHICLE STALLS AT ANY SPEED AND WHEN GOING UP A HILL. *AK THE CHECK ENGINE LIGHT HAD COME ON.

ENGINE AND ENGINE COOLING:ENGINE:GASOLINE

TOOK VEHICLE TO DEALER ON 11/13/2002 WITH CHECK ENGINE LIGHT ON. DEALER PERFORMED CHECK AND DETERMINED 2 02 OXYGEN SENSORS WERE BAD. SAID THEY WOULD ORDER THEM AND CALL ME TO BRING VEHICLE BACK IN. CHECK ENGINE LIGHT STILL ON CONTINUOUSLY. ENGINE SPEED RISES AND FALLS WITH NO PRESSURE ON ACCELERATOR. WHEN IN GEAR, SUDDEN ENGINE ACCELERATION CAUSES VEHICLE TO JUMP FORWARD UNEXPECTEDLY IT IS NOW 12/3/02. DEALER SAYS SENSORS HAVE NOT COME IN. WHEN QUESTIONED AS TO WHETHER THIS SENSOR PROBLEM IS COMMON WITH ALL TOYOTA TRUCKS WITH 4.7 LITER V8 ENGINE. THE SERVICE MAN WAS EVASIVE SAYING THERE HAVE BEEN SOME PROBLEMS. CONSIDERING THEY ARE HAVING TO ORDER A PART THAT IS NORMALLY STOCKED AT THE DEALERSHIP, AND CONSIDERING THE UNUSUAL LENGTH OF TIME IT IS TAKING THEM TO REPLACE THE DEFECTIVE SENSORS ON MY TRUCK. I AM OF THE OPINION THAT THIS IS A WIDESPREAD PROBLEM WITH THE POTENTIAL TO CAUSE ACCIDENTS. THIS PROBLEM SHOULD WARRANT A RECALL OF THESE TYPE VEHICLES TO CORRECT THIS SAFETY PROBLEM. DT
