What owners say about the structure
Verbatim from NHTSA complaints, newest first
“The frame is rusted almost in half a mechanic said it's not safe to drive it will kill someone. The car lot that is selling me the car said he can fix it but it's being held together by welds and c foam. He wants me to still pay for it. I've complained about not being able to drive over 45 without swaying badly and they keep doing stuff to it saying it's fixed and it's not. It's to dangerous to drive. I have a video of underneath but it won't let me upload it”
“The frame rusted and is available for inspection. My daughter was driving our 2000 Toyota 4Runner SR5 which I purchased new in 2000 when she noticed the truck started to wobble when she hit small bumps. I drove it to the garage the next day which is 2 miles from my house. It was doing the same for me. My mechanic went to put it up on the lift, he noticed that the frame rusted out. There was nothing he can do at this point. There are many complaints of the same issues with the 2000 Toyota 4Runners with the frames rusting out. If she was driving on the highway, this could have been a lot worse and possibly someone seriously injured or death. There were no warning lamps, messages, or other symptoms of the problem prior to the frame rusting out. The only one to inspect it was my mechanic.”
“The contact owns a 2000 Toyota 4Runner. The contact stated while at a local mechanic he was informed that the sub frame was completely rusted. The vehicle was diagnosed but not yet repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 140,000.”
“Frame on passenger side (front,left) is rotted. While I was driving on the highway I almost got in an accident because the frame gave out. Now I’m out of car and I don’t want to pay but I’m going to have to thousands of dollars to get the frame fixed. That’s money I don’t have as I am a recent college student trying to pay of his loans.”
“I REPORTED A SERIOUS SAFETY ISSUE SEVERAL YEARS AGO WITH A DEFECTIVE FRAME WELD ON MY 2000 TOYOTA 4RUNNER, WHICH CAUSED MY REAR DIFFERENTIAL SUPPORT TO SEPARATE FROM THE FRAME WHILE DRIVING AT 55-60 MPH. THIS CAUSED A SEVERE, UNEXPECTED SWAYING OF THE VEHICLE BACK AND FORTH AND ALMOST COMPLETE LOSS OF CONTROL”
“TRAVELING ON INTERSTATE AT 65 MPH AND HEARD A "POP." VEHICLE STARTED SWERVING BADLY -- TOTAL LOSS OF CONTROL. REAR END WAGGING HORRIFICALLY NEARLY HITTING CARS IN OTHER LANES. MANAGED TO GET TO SHOULDER BUT COULDNT SEE WHAT WAS WRONG. GOT VEHICLE OFF AT EXIT AND TO GARAGE. WAS TOLD FRAME SNAPPED AND REAR END CONTROL ARM NO LONGER ATTACHED REAR END TO FRAME. FRAME ROT EXTENSIVE. SCARY AS HELL. NO OTHER RUST ON VEHICLE. THOUGHT VEHICLE WOULD FLIP!”
