“Severe frame rust. 2 large holes on the inside of the frame just back from the front wheels and 2 large holes at the ends of the rear crossmember.”Owner report · Structure · Jan 2026
“While my mechanic was servicing a small exhaust leak on my vehicle he noticed that the chassis/frame of the vehicle was heavily corroded. He told me that he believe it was no longer safe to drive and that I contact Toyota. I had a local Toyota service center also look at it and they confirmed that the chassis/frame was heavily corroded and unsafe to drive.”Owner report · Unknown Or Other · Sep 2025
“Toyota has had issues with their frames rusting out and the 4th generation 4Runner is not exempt from this issue. My 2003 is requiring extensive work to keep it on the road safely due to frame rust. A recall to replace frames should be in place.”Owner report · Structure · Jan 2024

“The contact owns a 2003 Toyota 4Runner. The contact stated that upon taking the vehicle to several independent mechanics for servicing, he was informed that the subframe was significantly corroded and needed to be replaced. The vehicle was not repaired. The dealer was not notified of the failure. The manufacturer was notified of the failure and informed the contact the vehicle was not covered under recall. The failure mileage was approximately 115,000.”Owner report · Structure · Aug 2023
“The VSC system in the vehicle becomes disabled due to a firmware 'glitch' identified by Toyota when an emission system issue is detected by the onboard diagnostic system. The VSC system is listed as an 'essential safety feature,' so I'm curious why a recall was never ordered to patch defective firmware that can cause VSC to become disabled due to a completely unrelated emissions issue.”Owner report · Service Brakes · Jan 2023
“The contact owns a 2003 Toyota 4Runner. The contact stated that while the vehicle was at the tire retailer for tire replacement, the technician informed him that the subframe was corroded. The vehicle was then taken to an independent mechanic, who diagnosed that the passenger's side front and rear subframes were severely corroded, as well as the cross member. The mechanic advised the contact to stop driving the vehicle. The dealer was made aware of the failure and informed the contact that there was no recall associated with the VIN. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 165,000.”Owner report · Structure · Jan 2023
“Extensive rust through out frame, resulting in holes in structural members. Leaving frame in a weak and vulnerable state.”Owner report · Structure · Sep 2022
“There is severe rust on the frame, the rear is listing by 3/4 of an inch due to suspension rust, parts of the frame are perforated and lots of rust can fall out of drain holes when tapped. I am unable to steer the truck due to the intermediate steering column rust. The Tacoma was recalled for the same reason, I am assuming the 4runner has not been recalled because it was manufactured in greater numbers, and therefore more costly to repair, the danger of the severe rust is the same in both vehicles.”Owner report · Suspension · Aug 2022
“So much rust has developed the frame is literally giving out. Toyota admitted to a rust issue- it's now a safety issue with this generation of 4Runner. They did a recall on the same frame for Tacoma but not 4Runner.”Owner report · Structure · Jun 2022
“The frame of the car has been rusting at a significant rate in the last 4 years. Mechanic identified major rust issues that would make the vehicle not safe in case of an accident.”Owner report · Structure · May 2022
