What owners say about the structure
Verbatim from NHTSA complaints, newest first
“The contact owns a 2002 Toyota 4Runner. The contact stated that while inspecting underneath the vehicle, he noticed that there was a hole in the subframe and that the subframe and sway bar were corroded. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 160,000.”
“Frame is excessively rusted. The recall that already exists for this issue only covers certain frames from Japan made with this steel. However, the same frames were imported to America and a large percentage of 4Runners were made with the same steel and didn’t receive a recall. Mine is one of them.”
“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.”
“Premature rusted frame throughout, vehicle is garaged and well maintained 117,000 miles on my 2002 Toyota 4Runner. Auto body specialist estimates $3k-$4k to restore, at least.”
“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.”
“The contact owns a 2002 Toyota 4Runner. The contact stated that while receiving routine maintenance repair on the vehicle, the independent mechanic informed the contact that the subframe was rusted. The dealer was not contacted. The vehicle was not repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 136,000.”
