2003 Toyota 4Runner Suspension Problems

I have not actually had an incident yet, but have been advised by the Toyota service team that I should no longer tow trailers and should consider not driving it at all due to frame rust/perforation in front of the rear control arms. This has been a well cared for vehicle that is in otherwise great shape (It has had every repair the dealership has ever recommended) the vehicle was bought per the dealerships claim that it could be driven "forever" as long as the dealership takes care of it. And now I'm faced with a massive expense to repair or replace the vehicle.

I heard a loud noise (scraping-dragging) from the bottom of the engine area while driving on the highway This was a very dangerous and scary incident Pulled over and My fiancé checked under the engine A very large metal piece was dragging the road I did not hit a bump or anything. A body shop mechanic informed me that the chasis of the 4 runner was in extremely bad condition The 4Runner will not pass inspection because of this condition I respectfully request help in this matter

ADDING MY NAME TO THE LIST OF PEOPLE WHO HAVE EXPERIENCED EXCESSIVE AND PREMATURE FRAME RUST ON THEIR 4RUNNER, POTENTIALLY CAUSING UNSAFE CONDITIONS WHICH COULD LEAD TO A COLLISION. TOYOTA ADDRESSED THIS PROBLEM FOR THE TACOMA, SEQUOIA, AND TUNDRA OF THE SAME YEARS, AND THEY SHOULD DO THE SAME FOR THE 4RUNNER.

I HAVE BEEN IN CONTACT WITH TOYOTA SEVERAL TIMES OVER THE PAST 4 YEARS ABOUT RUST ISSUES WITH THIS FRAME, BUT THE REFUSE TO FIX IT. THEY RECALLED THE TACOMA, TUNDRA AND SEQUOIA OF THE SAME YEAR FOR THIS REASON. THE FRAME RUSTS AND FALLS APART. WHILE DRIVING UP MY ROAD I FELT THE REAR OF THE CAR SHIFT TO THE SIDE, I TURNED AROUND AND WENT STRAIGHT HOME TO FIND THE FRAME AT THE REAR PASSENGER TIRE BROKEN. I HAVE ATTACHED A PICTURE OF THE BROKEN AREA, BUT CAN SEND MORE PICTURES OF THE ENTIRE FRAME IF NEEDED.

I own a 2003 Toyota 4Runner with very low mileage for its age. It has been garage kept for most of its life. I was experiencing difficulty steering, and when I took the car to a mechanic, it was determined that the frame was prematurely rusted and rotted to a dangerous level putting my life at risk while driving it.

THE FRAME IS RUSTED BEYOND REPAIR AND THE VEHICLE HAS SPENT THE MAJORITY OF ITS LIFE IN A N UNDERGROUND GARAGE PROTECTED FROM THE ELEMENTS, AS WELL AS IN FLORIDA. IT HAS VERY LOW MILEAGE, AND NO OTHER SERIOUS PROBLEMS.

EXTREME RUST AND CORROSION IN FRAME, SUSPENSION COMPONENTS. THIS WILL LEAD TO CATASTROPHIC FAILURE AT SOME POINT IF HOLES AND FRAME DETERIORATION IS NOT ADDRESSED QUICKLY.

FRAME IS COMPLETELY ROTTED OUT RUSTED, GAS TANK STRAPS ARE ROTTED/RUSTED. REAR SWAY BARS ARE ROTTED OFF THE FRAME. THIS VEHICLE HAS THE SAME FRAME ISSUE AS THE TACOMA AND SEQUOIA FRAMES THAT ARE ON RECALL.

FRAME IS RUSTED OUT, EXCESSIVE RUST THROUGHOUT THE ENTIRE FRAME AND SUSPENSION COMPONENTS. SWAY BAR MOUNTS FOR REAR AXLE HAVE RUSTED OUT VEHICLE IS UNSAFE TO DRIVE

THE REAR TIRE ASSEMBLY RIPPED LOOSE FROM ITS MOUNTS UNDER NORMAL DRIVING CONDITIONS..A LOUD CLUNK NOISE....THEN .BRAKES WERE LOST AND THE ELECTRICAL SYSTEM SHOWED WARNING LIGHTS ON DASH BOARD...CAR IS NOT DRIVABLE...MASSIVE RUST AT FAILURE POINTS

REAR DRIVER SIDE CONTROL ARM BROKE OFF AT THE FRAME AFTER STRIKING POTHOLE AT HIGHWAY SPEED. AFTER THE FAILURE THE VEHICLE WAS VERY HARD TO CONTROL AND ALMOST LED TO A ROLLOVER. THE VEHICLE WAS UNABLE TO BE DRIVEN AND HAD TO BE TOWED. TOYOTA RECALLED TUNDRA'S, TACOMA'S, AND SEQUOIA'S FOR FRAME REPLACEMENT SO IT IS A KNOWN PROBLEM. WILL TOYOTA BE HELD LIABLE FOR ACCIDENTS RESULTING FROM PREMATURE FRAME FAILURE? BY RECALLING THE OTHER MODELS THEY OBVIOUSLY ACKNOWLEDGED IT WAS A PROBLEM AND 4RUNNERS SHARE THE SAME PLATFORM AS THE TACOMA SO WHY WERE THEY NOT INCLUDED?

MY 2003 TOYOTA 4 RUNNER SR5 WAS SWAYING BACK AND FORTH AT SPEEDS UP TO 35 MPH SOMETHING IS WRONG THINKING MAYBE THE SWAY BARS SO TOOK IT TO A MECHANIC AND AFTER HE DROVE IT AND PUT IT UP ON A LIFT HE WAS FRIGHTENED ON HOW MUCH RUST AND SEPARATION ON THE FRAME ESPECIALLY THE REAR PASSENGER SIDE RIGHT NEXT TO THE MUFFLER COMPLETE SEPARATION AND THEN YOU WALK TO THE MIDDLE ANY DAY NOW THAT WOULD HAVE SEPARATED .I WAS TOLD TO TO HAVE A TOW TRUCK TAKE IT BACK TO MY HOUSE WHICH IS ABOUT TWO-THREE MILES AWAY WHICH I DID BUT NOW IT SITS IN MY GARAGE - AND WITH ONLY 139,000 MILE ON IT NOT ABLE TO DRIVE OR SELL UNLESS ITS FOR JUNK.

VEHICLE FRAME IS SEVERELY RUSTED AND ROTTED TO THE POINT WHERE THERE ARE HOLES IN THE FRAME ITSELF MAKING IT EXTREMELY UNSAFE TO DRIVE. OTHER TOYOTA TRUCKS AROUND THE SAME YEAR HAVE BEEN RECALLED WITH SIMILAR FRAME ISSUES, DOES NOT MAKE ANY SENSE WHY TOYOTA HAS NOT RECALLED THE 2003 4RUNNER FRAMES YET. VEHICLE IS OVER 205,000 MILES AND WOULD PROBABLY RUN ANOTHER 200K IF NOT FOR THE FRAME WHICH MAKES THIS CAR ALMOST UNDRIVE-ABLE. FRAME TO BE REPLACED ASAP.

I purchased this 2003 Toyota 4Runner in 2018 under what I assumed was prime condition, for a vehicle that spent the majority of its life in Nebraska/Kansas before I moved to Texas in 2021. At 87,400 miles at the time of purchase, the vehicle had no visible damage to the exterior besides a few paint chips, some minor hail damage and scratches, and some easily fixed surface rust in the paint on the tailgate. The previous owner had driven it leisurely and had kept the miles low after 15 years. The car has had some mechanical issues, but nothing out of the ordinary outside of some regular maintenance over the first few years. Being close to 100,000 miles, the timing belt and pump was replaced around 98,000 miles. Other issues have been fixed periodically, please reference the attached files. After joining a Toyota 4Runner 4th Generation Facebook group and seeing a post about another's issues with rust damage in October 2020, I decided to take a look at my own frame. I then inspected my own vehicle, and found significant frame rot damage. It is extensive, with significant rust to the frame, with large holes and soft patches that question the integrity of the frame and the safety of the vehicle on the road. Every time I hit a small bump or pothole, I fear the frame will crack and I will lose control as others have. I have not sought out professional repairs due to the extensive cost, and am awaiting the outcome of a current class action lawsuit by the Bell Legal Group. The 4th Generation Toyota 4Runner (2003-2009) is built on the exact same frame as the Toyota Tacoma of that era, yet while the Tacoma was recalled for frame rot, the 4Runner was not included, which I believe to be a gross oversight in previous legal proceedings. The 2003-2009 Toyota 4Runner is a reliable vehicle, but poses significant frame rot issues much earlier than should be expected.

TL* THE CONTACT OWNS A 2003 TOYOTA 4RUNNER. THE CONTACT STATED THAT THE SUBFRAME WAS CORRODED CAUSING BOTH REAR CONTROL ARMS TO DETACH WHILE DRIVING. THE CONTACT INSPECTED UNDER THE VEHICLE AND NOTICED THERE WERE SEVERAL SPOTS COVERED WITH A BLACK TAPE AND PAINTED OVER TO CONCEAL THE RUST AND HOLES. THE CONTACT STATED THAT THE REAR TIRE MOVE FORWARD AND BACKWARD CAUSING THE TIRES TO DAMAGE THE BUMPER AND THE PLASTIC TRIM PANEL. THE VEHICLE WAS TOWED TO THE CONTACT'S RESIDENCE. THE CONTACT CALLED AAA AND INFORMED THEM OF THE FAILURE AND WAS INFORMED TO CONTACT NHTSA. NEITHER THE DEALER NOR THE MANUFACTURER WERE MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 200,000.

THE VEHICLE FRAME HAS MULTIPLE PERFORATIONS GREATER THAN 10MM. ONE SUCH PERFORATION HAS CREATED A CRACK ON THE FRAME JUST IN FRONT OF THE RIGHT REAR LOWER CONTROL ARM MOUNT. IF THIS VEHICLE WERE TO HIT A BAD ENOUGH BUMP OR POT HOLE, THERE EXISTS A POSSIBILITY THE FRAME COULD SNAP AND ALLOW THE CONTROL ARM TO BECOME FREE AND THE VEHICLE WOULD LOSE CONTROL

The contact owns a 2003 Toyota 4Runner. The contact stated that while driving at limited speeds of 45 mph, the vehicle would wobble and swerve and was very unstable. The vehicle was taken to a Certified Auto Mechanic Shop and an independent mechanic who diagnosed that the failure was caused by severe rusting, perforation and corrosion of the rear subframe and suspension system. The vehicle was also driven to Muffler Shops in Bladensburg, MD on 8-20-2021, and on 10 -22-2021 to Hyattsville Toyota's Certified Toyota Collision Center for Repair Estimates of $4,000.00 and $7,268.00. The vehicle frame manufactured by Dana Holding Corporation which really requires fixing or replacing was not yet repaired. The Toyota manufacturer and local dealer Global Auto Outlet were notified of the failure. The approximate failure mileage was 1 85,000. The used vehicle was purchased from Global Auto Outlet in Temple Hills, MD for $9,552.24 on 8 -1-2019 with 175,000 miles on the odometer. The windshield had a crack in it, the air conditioning & emergency brake didn't work. The Complainant hadn't noticed the perforated excessive rust corrosion on the undercarriage of the vehicle until numerous months afterwards. Moreover, at the time of the purchase the Owner also didn't notice that the spare tire carrier was rusted, as well as undiscovered that the wrong size 265/65/17 spare tire it was held in was perforated and flat. After the purchase of the vehicle shortly later, the exhaust tailpipe rusted broke first and the muffler had to be replaced which costed $258.79. The Owner was nervously forced to operate a more than unsafe motor vehicle for up to 6 months.

I TOOK MY 2003 TOYOTA 4RUNNER INTO MY LOCAL MECHANIC TO DO MY ANNUAL STATE SAFETY INSPECTION AND THE MECHANIC INFORMED ME THE FRAME WAS TOO RUSTED TO PASS INSPECTION. FURTHERMORE, HE SAID THAT THE RUST WAS SO SEVERE IT HAD SEPARATED THE SUSPENSION FROM THE FRAME. HE TOLD ME IT WAS THE WORST FRAME RUST HE HAD EVER SEEN AND THAT THE CARS FRAME LOOKED LIKE IT WAS 20 YEARS OLDER THEN IT WAS. IT WAS TOTALLY RUSTED THROUGH IN SEVERAL SPOTS. I CALLED TOYOTA TO SEE IF THEY WOULD WORK WITH ME TO FIX THIS ISSUE AND THEY OFFERED NO HELP. ALL THE OTHER CARS BUILT ON THIS FRAME HAVE BEEN RECALLED, I'M NOT SURE WHY THIS ONE HASN'T BEEN.

THE RUST ON THE FRAME OF THIS VEHICLE IS UNLIKE ANYTHING I'VE SEEN IN COMPARISON TO IT'S AGE. I WORK ON VEHICLES FREQUENTLY AND HAVE NOT SEEN ANYTHING LIKE THIS IN A MODERN AGE VEHICLE, AND VEHICLES THAT ARE OVER 40 YEARS OLD THAT I OWN OR WORK ON DON'T HAVE RUST THAT IS REMOTELY THIS BAD. UPON FURTHER INVESTIGATION, I FOUND THE ENTIRE WELD LINE OF THE FRAME RAILS TO BE CORRODED THROUGH IN AN APPROXIMATELY 28" SECTION. WITH FURTHER INVESTIGATION, THE ENTIRE BOTTOM SECTION OF THAT RAIL WAS RUSTED OUT TO BE EXTREMELY THIN AND SEPARATED AT THE SEAM, ENTIRELY COMPROMISING THE INTEGRITY OF THE FRAME RAIL. 2 OF THE BODY MOUNTS ARE ALSO RUSTED OUT AS WELL AS SOME OF THE SUSPENSION MOUNT COMPONENTS. THE VEHICLE IS AT RISK FOR HAVING THE SPRING AND STRUT ASSEMBLY OR THE CONTROL ARM ASSEMBLY DETACHING FROM THE FRAME UNDER NORMAL OPERATION CONDITIONS. THIS IS AN INCREDIBLE SAFETY RISK AS IT COULD RESULT IN THE VEHICLE LOSING ALL STEERING CONTROL. LUCKILY IT WAS FOUND BEFORE AN ACCIDENT OCCURRED.

I HAVE A 2003 4RUNNER WITH SEVERE FRAME RUST THROUGH MAKING THE VEHICLE A HAZARD TO DRIVE AND TO OTHERS ON THE ROAD. THIS IS CLEARLY CONSISTENT WITH TOYOTA'S OTHER RECALLS.
