2003 TOYOTA 4RUNNER Complaints

The frame is completely rusted through and soon will be unable to support the steering, engine or drive train. The problem was confirmed to me by an independent service center that I have used for 10 years and I trust.

Car inspection at a service center revealed advanced rusting of the frame. I was told this could be dangerous.

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

The frame has rusted almost completely through near the front upper and lower control arms near the cross member there. The passenger side is so bad the welder I took it too sad he couldn’t repair it without doing the crossmember section and all. The driver side is not at bad but doesn’t look to hot. The crossmember where the radiator sits is also starting to completely rot away

Frame is rotted out and brake lines attached to the frame as well as every suspension component. Car failed inspection deemed unsafe to drive. This problem has been addressed for Tacoma, tundra and sequoia but not 4runner. These frames have the same issue as those and needs to be repaired by Toyota due to lack of rust and corrosion protection. There’s no reason 4runner should be overlooked for the same issue as the other full frame trucks.

Frame rusted to the point the shop won’t fix the brakes and allow me to drive the car. The brake line rusted through since it was attached to the frame and when repairing the brakes they found the frame rusted too bad and coming apart. Looking online this seems to be a common problem with this year Toyota 4Runner.

Three mechanics said the frame was rusted with holes and is unsafe to drive. The vehicle is not inspectable, so had to have mechanic weld Steele on frame to be able to pass inspection.

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.

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.

TL* THE CONTACT OWNS A 2003 4RUNNER. THE CONTACT STATED THAT WHILE THE VEHICLE WAS BEING REPAIRED, HE WAS INFORMED THAT THE UNDERCARRIAGE AND SUBFRAME OF THE VEHICLE WAS EXTREMELY RUSTED. THE VEHICLE HAD NOT BEEN TAKEN TO A DEALER OR INDEPENDENT MECHANIC TO BE INSPECTED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 139,000.
