2003 Toyota Tundra power train problems

“The frame has failed by rusting through and continues to the brake line. It is available for inspection. The truck is no longer safe to drive due to the rust and brake issues. The truck frame could have failed in traffic causing harm to myself and other drivers. The problem has been confirmed by Yingling’s in Topeka, KS, Lewis Toyota in Topeka and Crown Toyota in Lawrence, KS. They have all done inspections of the truck frame. The problem first appeared when it was taken to Yinglings in 2018 to replace the muffler.”

“2003 TOYOTA TUNDRA FRONT END MAKING A SEVERE GRINDING, SQUEAKING, AND KNOCKING NOISE. THE CV AXLE BOOTS ARE DESTROYED AND SEEMS LIKE THE WHEEL BEARINGS AND HUB IS GOING OUT QUICKLY AS WELL. ALSO HAVE TRANSMISSION LEAKAGE AND NOISE WHEN TURNING. VEHICLE ONLY HAS 86,000 MILES ON IT.”

“STEERING COLUMN SHIFT BRACKET BROKE IN 3 PLACES WHEN TRYING TO SHIFT FROM PARK TO DRIVE, MAKING SHIFTING IMPOSSIBLE. SEE PICTURES FROM 2 OF 3 FRACTURE LOCATIONS, 3RD FRACTURE IS AT AN ATTACHMENT SCREW (NOT SHOWN). THIS IS CAUSE BY AN PUNDERDESIGNED PART MADE OF INFERIOR CAST ALUMINUM. THERE ARE THOUSANDS OF REPORTS OF THIS PROBLEM ON TUNDRAS AND OTHER TOYOTA MODELS WITH SAME DEFECTIVE BRACKET. THIS DANGEROUS DEFECT MUST BE RECALLED AND FIXED BY TOYOTA WITH A REDESIGNED PART.”

“I AM A RETIRED TOYOTA MASTER DIAGNOSTIC TECHNICIAN. AS I WAS REPLACING MY REAR BRAKE LINES ON MY 2003 TUNDRA-WITH 79,962 MILES, I SAW A FLUID LEAK UNDER REAR OF VEHICLE. UPON INSPECTION I FOUND THE REAR DIFFERENTIAL HOUSING HAS RUSTED SO BADLY THAT THE GEAR OIL IS LEAKING THROUGH THE HOUSING. UNFORTUNATELY THE ONLY REMEDY IS THE REPLACEMENT OF THE COMPLETE REAR AXLE/DIFFERENTIAL ASSEMBLY. THE FRAME HAS ALREADY BEEN REPLACED-UNDER RECALL. THE REAR BRAKE LINES HAVE RUSTED THROUGH WHICH HAD TO BE REPLACED- AT MY EXPENSE. ALSO THE POWER STEERING LINES HAVE ALSO RUSTED THROUGH WHICH ALSO HAD TO BE REPLACED- AT MY EXPENSE. IT IS OBVIOUS THAT THE MATERIAL THAT WAS USED IS OF VERY LOW QUALITY CAUSING VERY DANGEROUS SITUATIONS.IE; LOSS OF VEHICLE CONTROL DUE TO DIFFERENTIAL LOCK-UP, LOSS OF VEHICLE BRAKING DUE TO RAPID FLUID LOSS, LOSS OF VEHICLE STEERING CONTROL DUE TO RAPID FLUID LOSS. I AM AMAZED THAT TOYOTA MOTOR CO. WILL NOT STAND BEHIND THE PRODUCT THEY SOLD-WITHOUT BEING FORCED TO. ONE QUICK LOOK UNDER A 2003 TUNDRA IS ALL IT TAKES TO SEE THAT LOW/POOR QUALITY HARDWARE AND MATERIALS WERE USED. WITHOUT REPAIR AND/OR REPLACEMENT OF ABOVE STATED COMPONENTS SOMEONE…”

“TOYOTA HAD A RECALL OF RUSTED OUT FRAMES FOR 2003 TOYOTA TUNDRA TRUCKS. MINE WAS REPLACED, BUT NOW THE DIFFERENTIAL HAS RUSTED OUT AND IT REQUIRES AN ENTIRE NEW REAR AXLE. I FILED A COMPLAINT WITH TOYOTA CORPORATE AND WAS TOLD SINCE MY VEHICLE IS OUT OF WARRANTY THEY WILL NOT STAND BY THEIR PRODUCT AND REPLACE AN OBVIOUSLY DEFECTIVE PART. THIS DEFECT COULD CAUSE THE REAR END TO LOCK UP WHILE DRIVING AND POSSIBLE CAUSE AN ACCIDENT WITH INJURIES.”
