2002 Toyota 4RUNNER suspension problems

SUSPENSION

The contact owns a 2002 Toyota 4Runner. The contact stated that while driving 60 MPH through a slight right curve, the vehicle independently shifted from side to side without warning nearly causing the vehicle to flip. The contact had an independent mechanic inspect the vehicle and the mechanic discovered severe corrosion throughout the entire subframe of the vehicle. The mechanic informed him that the entire subframe needed to be replaced to ensure safe driving. Neither the dealer nor the manufacturer had been notified of the failure. The vehicle had yet to be repaired. The failure mileage was approximately 115,000.

Had vehicle inspected on Oct. 1 ,2021 for road trip to North Carolina from Washington, DC. Was informed that my vehicle is unsafe by the automotive shop (name withheld) due to [rusting] frame front suspension components' threads rusted off on bolts that hold suspension, control arms, and shocks on both front and rear areas + body of vehicle located where shocks bolt to the body. I also had two other shops (names withheld) assess the state of the frame and suspension + and was told that the vehicle has maybe 1 year or so until the frame falls apart. Given I am the original owner, have gargage-kept my vehicle, have very low-mileage - 74,000 miles, and have maintained the vehicle immaculately and am aware of rusting problems with other Toyota [truck] frames, etc. this seems to be a defect in the manufacturing process. I know there have been recalls on Toyota's other trucks due to Toyota's failure to add [enough?] rust inhibitor/preventative to the molten steel when forming the frame for many models of their trucks.

After having my 4 runner in for routine maintenance, my mechanic informed me that my frame was in bad condition and rusting through. Doubtful it has a year left and he advised me to junk it as fast as I can. 180;000 miles - so much for Toyota’s lasting a long time.

WHEN I HAD MY STATE INSPECTION IN JANUARY OF 2020, THE MACHANIC TOLD ME THE FRAME OF THE VEHICLE WILL NOT PASS INSPECTION AGAIN. IT IS SEVERELY RUSTED THROUGH AND IN HIS OPINION IS UNSAFE TO DRIVE. A FEW WEEKS LATER, I WAS TRAVELLING TO MY FATHER'S RESIDENCE AND THE BRAKES GAVE OUT. THE TECHNICIAN THAT REPAIRED MY BRAKE LINE ALSO TOLD ME AND DOCUMENTED ON THE BILL THAT THE TRUCK IS REALLY NOT SAFE TO DRIVE. I HAVE OWNED THIS VEHICLE FOR 18 YEARS, AND ONLY DRIVEN IT FIVE WINTERS. I WASH THE TRUCK NUMEROUS TIMES DURING THE WINTER TO REMOVE SALT. IT IS MY ONLY VEHICLE, AND I CANNOT AFFORD A NEW ONE. WHY WASN'T THIS INCLUDED IN THE FRAME RECALL FROM TOYOTA?!? NOW I'M NERVOUS ABOUT MY SAFETY AND THOSE ON THE ROADWAYS.

I HAVE A 2002 TOYOTA 4RUNNER WITH A SEVERELY RUSTED FRAME. MY VEHICLE HAS LESS THAN 70K ORIGINAL MILES ON IT, NO BODY RUST, BUT AN EXTREMELY RUSTED UNDERCARRIAGE AND FRAME. I FEEL IT IS UNSAFE TO CONTINUALLY DRIVE WITH THIS PROBLEM, AS IT WILL ONLY GET WORSE AND COULD AFFECT OTHER COMPONENTS SUCH AS STEERING, SUSPENSION, BRAKES, ETC. SEEING AS HOW TOYOTA HAS ALREADY HAD A CLASS ACTION LAWSUIT AGAINST THEIR TRUCKS OF THE SAME YEAR FOR UNSAFE RUSTED FRAMES, I FEEL MY 4RUNNER SHOULD BE INCLUDED IN THE FRAME REPLACEMENT RECALL.

I WAS DOING AN OIL CHANGE AND NOTICED THAT THE FRAME WAS RUSTED VERY BADLY . I THINK THAT THERE SHOULD BE A RECALL ON THIS MODEL 3RD GEN 4RUNNER (1999-2002)THIS IS THE SAME FRAME AS THE TRUCK THAT WAS RECALLED ,SO THIS SHOULD BE INCLUDED .IF THIS FRAME BREAKS IT WILL HURT OR KILL SOME ONE .

THIS IS YET ANOTHER COSTUMER OF THE 4RUNNER 3RD GENERATION COMPLAINING ABOUT THE FRAME RUSTING OUT. THERE NEEDS TO BE RESPONSABILITY FOR THE BAD FRAMES ON THIS YEAR 4RUNNER. MY FRAME HAS HOLES IN THE REAR CONTROL ARM ATTACHMENT AREA AND MORE RUST ALL THROUGHOUT ENTIRE FRAME. I'M DOING ALL I CAN TO KEEP MY FRAME FROM GETTING ANY MORE RUST ON IT AND KEEPING IT SAFE TO BE ON THE ROAD. I STRONGLY BELIEVE TOYOTA SHOULD ALSO HAVE A FRAME RECALL FOR THE 4RUNNER LIKE IT DID FOR THE TUNDRA TACOMA AND SEQUOIA FRAMES.

FRAME RUST ON THE INSIDE PORTION FOR THE FRAME. 33" HOLE RUSTED THROUGH COMPLETELY ON PASSENGER SIDE. RUST CONTINUES ABOUT 80% OF THE WAY THROUGH THE REAR LOWER CONTROL ARM MOUNT. DRIVER'S SIDE HAS A SIMILAR AMOUNT OF SEVERE RUST THAT HAS WEAKENED THE STRUCTURAL INTEGRITY OF THE FRAME TO THE POINT WHERE IT IS NO LONGER SAFE TO DRIVE. SHOULD THE CO TROLL ARM MOUNT FINISH RUSTING THROUGH, THE AXLE WILL NO LONGER BE ATTACHED TO THE FRAME ON THAT SIDE. THERE IS NOTICBLE FLEX AND SOUND ASSOCIATED WITH THE FRAME ROT. IT IS ONLY A MATTER OF TIME BEFORE THE CONTROL ARM MOUNT DISCONNECTS COMPLETELY, OR THE FRAME BUCKLES.

TRACTION CONTROL SYSTEM MALFUNCTIONS INTERMITTENTLY WHILE DRIVING AROUND CURVES. SEVERAL TIMES WHILE DRIVING APPROXIMATELY 30-40 MILES PER HOUR ON A MOUNTAIN ROAD, THE ANTI SKID LIGHT ILLUMINATES WITHOUT WARNING ON A DRY PAVED ROAD WITH A SUBSEQUENT SUDDEN PULL TO THE RIGHT AND "GRINDING" NOISE. THIS HAS HAPPENED MULTIPLE TIMES WITHOUT WARNING. THE TOYOTA DEALER CAN NOT HELP, SINCE HE CAN NOT REPLICATE THE PROBLEM. THE LATEST OCCURRENCE PULLED THE VEHICLE ACROSS THE CENTER LINE INTO THE ONCOMING TRAFFIC LANE. (HAD THERE BEEN ONCOMING TRAFFIC THIS WOULD HAVE BEEN A SERIOUS ACCIDENT)

I TOOK MY VEHICLE IN FOR A ROUTINE OIL CHANGE RECENTLY AND THE TECHNICIAN SAID THAT I HAVE SOME MAJOR RUST ISSUES ON MY REAR AXLE AND DRIVETRAIN. HE SHOULD ME WHEN IT WAS ON THE LIFT. HE EXPLAINED TO ME THAT THE BOLT AND CLIP THAN HOLDS THE BRAKE LINE DOWN ON THE REAR DIFFERENTIAL HAD RUSTED AND BROKEN OFF OF THE DIFFERENTIAL COVER. THE REAR DIFFERENTIAL IS NOW LEAKING GEAR OIL. THE TECHNICIAN ADVISED ME THAT IT IS TOO RISKY TO ATTEMPT TO REPAIR AS IT MAY CAUSE THE ENTIRE DIFFERENTIAL TO BE DAMAGED AND THE WHOLE REAR AXLE WOULD NEED TO BE REPLACED. THE TECHNICIAN ALSO SAID THAT IT IS A RISK TO DRIVE THE VEHICLE AND IS POSSIBLY UNSAFE TO KEEP DRIVING. HE STATED THAT IT IS UNKNOWN HOW MUCH LONGER I WOULD BE ABLE TO DRIVE IT UNTIL THE REAR AXLE CEASES.

VEHICLE WAS STATIONARY. WHILE REPLACING EXHAUST SYSTEM COMPONENTS. FOUND WHAT APPEARED TO BE MINOR RUST ON THE PASSENGER (RIGHT) SIDE REAR SUSPENSION MOUNT. FURTHER INVESTIGATION UNCOVERED A LARGER AREA OF RUST ALONG THE 3 WELDS ON THE INNER FRAME RAIL. CUT / GROUND THE METAL BACK TO GOOD METAL AND AM IN THE PROCESS OF PATCHING FOR MY YEARLY MAINE VEHICLE INSPECTION. EITHER TOYOTA HAS BUILT AN INFERIOR FRAME OR THE NEWER CHEMICALS BEING USED TO KEEP THE ROADS CLEAR IN THE WINTER TO BE THE CAUSE OF THIS RUST WHICH COULD CAUSE THE REAR SUSPENSION TO FAIL AT THIS POINT IN THE FRAME AND CAUSE A ACCIDENT.

SKID PLATES ON FRONT AND FUEL TANK SO RUSTED MUST REMOVE. NOW NOTHING IS PROTECTING THE FUEL TANK.

AFTER BUYING THIS VEHICLE I WAS UNDERNEATH VEHICLE TO REPAIR A AXLE SEAL LEAKING AND FOUND EXTENSIVE FRAME RUST ON PASSENGER REAR OF FRAME. BY EXTENSIVE I MEAN THE FRAME WAS RUSTED COMPLETELY THROUGH! I HAVE LIVED IN OHIO ALL OF MY LIFE AND HAVE NEVER SEEN A VEHICLE WITH THIS MILEAGE AND OF THIS YEAR HAVE SUCH SEVERE FRAME RUST! AFTER FURTHER INSPECTION I NOTICED REAR END HOUSING WAS ALSO SEVERELY RUSTED. THE RUST ON THE FRAME IS SEVERELY PERFORATED AT POINT WHERE TRAILING ARM FOR THE REAR END ATTACHES TO THE FRAME! I WAS NOT AWARE OF THIS ISSUE BEFORE BUYING VEHICLE BUT AFTER SOME RESEARCH HAVE FOUND THAT THIS IS DEFINITELY A MANUFACTURER DEFECT OF SOME SORT! THESE VEHICLES ARE NOT SAFE TO DRIVE WITH THESE FRAMES IN THIS CONDITION AND TOYOTA IS AWARE OF THIS!

THE FRAME ON THE 2002 4-RUNNER HAS COMPLETELY CORRODED AND CAUSED THE TOYOTA DEALERSHIP TO DEEM THE VEHICLE UNSAFE FOR DRIVING. EVEN THOUGH THIS A RECOGNIZED DESIGN FAILURE, TOYOTA REFUSES TO COVER THE COST OF REPLACEMENT. TOYOTA HAS RECALLED TUNDRA MODELS FOR THIS DEFECT, BUT REFUSES TO ACKNOWLEDGE THE 4-RUNNER DESIGN FLAW SINCE IT WAS MANUFACTURED COMPLETELY AT THEIR HINO JAPAN PLANT.
