THE ISSUE WITH MY TOYOTA IS A RUSTED FRAME...RUSTED TO THE POINT THAT I WAS ADVISED TO PARK IT AND NEVER DRIVE IT AGAIN WITHOUT A NEW FRAME.

THE ISSUE WITH MY TOYOTA IS A RUSTED FRAME...RUSTED TO THE POINT THAT I WAS ADVISED TO PARK IT AND NEVER DRIVE IT AGAIN WITHOUT A NEW FRAME. ALTHOUGH IT IS A 2001 WITH 193,000 MILES, IT MECHANICALLY IS IN GREAT CONDITION. EXTERIOR AND INTERIOR IN GOOD CONDITION, AS WELL. I FIRST NOTICED THE VEHICLE HAD A FLOATING SENSATION ON THE HIGHWAY, AT TIMES FEELING LIKE I HAD NO CONTROL WITH THE STEERING WHEEL. AFTER ANOTHER 1-2 HRS OF DRIVING, I NOTICED THAT WHEN DRIVING OVER BUMPS OR DIPS IN THE ROAD, THE TRUCK WOULD ROCK SLIGHTLY SIDE TO SIDE. IT WAS SIGNIFICANT ENOUGH THAT ITEMS IN MY BACK SEAT ROCKED, AS WELL. AFTER SEVERAL MORE DAYS AND HOURS OF DRIVE-TIME THEREAFTER, THE ROCK ADVANCED TO THE POINT WHERE MY ENTIRE VEHICLE WAS ROCKING SO VIOLENTLY WHEN CROSSING A BRIDGE @40MPH, I HAD NO CONTROL OVER THE VEHICLE. EVEN BRAKING DID NOT IMMEDIATELY STOP THE ROCKING. AFTER THAT INCIDENT, I STOPPED DRIVING THE VEHICLE UNTIL I HAD IT SCHEDULED TO TAKE IN TO THE MECHANIC. THE PROBLEM WITH THE RUSTED FRAME WAS IDENTIFIED ALMOST IMMEDIATELY. I WAS TOLD THAT THE HOLES AND RUST WERE SO EXTENSIVE, THAT IT WAS ONLY A MATTER OF A SHORT AMOUNT OF TIME BEFORE THE FRAME WOULD NOT ONLY BREAK APART, BUT BREAK INTO SEVERAL PIECES. I WAS TOLD THAT IT WAS UNSAFE TO DRIVE AND THAT THE ONLY SOLUTION WAS A FRAME REPLACEMENT. I UNDERSTAND THAT TOYOTA HAD A RECALL ON THEIR TAUCOMA FRAMES FOR THAT SAME YEAR, BUT WILL NOT CORRECT THE IDENTICAL PROBLEM WITH THE 4RUNNER FRAME. I HAVE AN OTHERWISE WONDERFUL VEHICLE SITTING IN MY DRIVEWAY THAT IS TOO DANGEROUS TO DRIVE BECAUSE OF TOYOTA'S KNOWN, FAULTY, UNSAFE FRAME.
TL* THE CONTACT OWNS A 2001 TOYOTA 4RUNNER. WHILE REPLACING THE SHOCKS ON THE VEHICLE, THE CONTACT NOTICED SEVERE RUST ON THE FRAME AND A HOLE APPROXIMATELY 3 AND 1/2 INCHES WIDE UNDER THE DRIVER SIDE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED. THE APPROXIMATE FAILURE MILEAGE WAS 182,000.
WHILE CHANGING MY OIL, I NOTICED A FEW NICE SIZE HOLES IN THE FRAME, IN FRONT AND BESIDES THE MUFFLER. I WONDERING IS IT SAFE FOR ME AND MY FAMILY TO DRIVE ON A REGULAR BASIS.
MASSIVE RUST AND DETERIORATION ALONG INSIDE PANEL OF FRAME ON PASSENGER SIDE REVEALED ONCE EXHAUST SYSTEM WAS REMOVED FOR REPLACEMENT. DETERIORATED SECTION WAS ABOUT 24" LONG FROM REAR AXLE MOUNT TO CENTER STABILIZER BAR. UNKNOWN DETERIORATION ON DRIVER SIDE DUE TO LOCATION OF FUEL TANK.
TL* THE CONTACT OWNS A 2001 TOYOTA 4RUNNER. WHILE PERFORMING AN OIL CHANGE, THE TECHNICIAN NOTICED THAT THE REAR PASSENGER SIDE OF THE FRAME WAS COMPLETELY CORRODED. THE TECHNICIAN STATED THAT THE FRAME HAD TO EITHER BE RE-WELDED OR REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILU…

MASSIVE RUST CORROSION AND PIECES BREAKING AWAY LOCATED UNDERNEATH ENTIRE VEHICLE. THE RUST WITH BREAKAGE HAS INTENSIFIED GREATLY IN THE LAST COUPLE OF YEARS AND REQUIRED WELDING THIS YEAR TO PASS INSPECTION BECAUSE THE VEHICLE WAS UNSAFE. THE WELDING CONSISTED OF WELDING THE FRAME RAIL WHERE THE REAR SUSPENSION MOUNTS AND A NEW BRACKET HAD TO BE WELDED ON THE AXLE HOUSING THAT HOLDS AN UPPER REAR STRUT ROD BECAUSE IT RUSTED OFF. BOTH WERE ON THE PASSENGER SIDE OF VEHICLE. THIS VEHICLE ONLY HAS 101,000 MILES AND IS WASHED AND WAXED ON A REGULAR BASIS.
THE GRAM HAS RUST PERFORATION IN WHICH THE LEFT REAR CONTROL ARM HAS SEPARATED FROM THE FRAME. WHILE I WAS DRIVING A HEARD A POP AND STARTED TO LOSE PROPER CONTROL IN STEERING VEHICLE.
SINCE I GOT THE CAR, THE IGNITION KEY DOES NOT GET IN PROPERLY AND SOMETIMES DOES NOT START THE CAR. THE MOVEMENT OF THE WHEEL HELPS SOMETIMES. THERE HAVE ALSO BEEN LEAKING ENGINE COVERS THAT NEEDED TO BE REPLACED. THE STRUCTURE GETS RUSTY AND THERE IS PROBLEM WITH TRANSMISSION.
