What owners say about the structure
Verbatim from NHTSA complaints, newest first
“The contact owns a 2007 Toyota 4Runner. The contact stated that the vehicle was swaying while driving approximately 35 MPH. There was no warning light illuminated. Additionally, the subframe was corroded. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure. The approximate failure mileage was 100,000.”
“I was having front brakes repaired, and mechanic called me over to lift to see under the car. Extremely rusty, flakes of metal coming off. He advised I do not even try and put it on a lift again, as he does not trust the structural integrity. He advised that it was definitely not normal, and not in keeping with the otherwise excellent and well cared for car.”
“The frame on my 4-Runner is rusted out to the point of being borderline unsafe, as per the Toyota Dealer. I don't have a scanner otherwise I would upload the pictures. The invoice from the dealer has my contact info. Not sure if you want that info.”
“The Undercarriage of my 2007Toyota 4runner sport has irregular rusting issue. The truck has 128,000 miles on it and has been well maintained and garaged most of its life. I was under it the other day to check the exhaust system and noticed the frame is rusting like no other car I know of. Even cars that sat in junkyards for decades. I know they had a recall for similar issues with other vehicles within the same year. However, when I spoke with Toyota they were uninterested in helping me and told me it was my problem. Other than the frame rust the truck is in perfect condition. Is this something that you can help me with. I see I am not alone having this issue and that it is well reported. Please let me know what my options are for getting this defect corrected by Toyota. Thanks, [XXX]”
“Excessive frame rust on the frame itself and on suspension components including control arms and support brackets. Toyota dealership stated that rust could be an issue with maintenance.”
“RECENTLY LOOKED AT 2007 TOYOTA 4RUNNER LIMITED V8 FOR SALE TO REPLACE MY 2005 LIMITED THAT HAS SEVERE FRAME CORROSION AND DISCOVERED THAT THIS VEHICLE TOO HAS NEARLY THE EXACT SAME CORROSION ISSUES. THE REAR OF THE FRAME BY THE BUMPER, WHERE THE CONTROL ARMS AND RADIATOR ARE ATTACHED TO THE CHASSIS AND FRAME RAILS ARE SO BADLY CORRODED YOU CAN PUSH YOUR FINGER THROUGH THE METAL. HOW MUCH MORE EVIDENCE DOES NHTSA NEED TO DEMAND TOYOTA RECALL THESE VEHICLES? LOOK AT THE HUNDREDS OF COMPLAINTS TO NHTSA AND THOUSANDS OF OWNERS ONLINE POSTING PICTURES AND VIDEOS OF THEIR VEHICLES RUST ISSUES. THERE IS A MAJOR PROBLEM WITH THESE VEHICLES CORRODING JUST LIKE THE OTHER TOYOTA BODY ON FRAME PRODUCTS THAT WERE RECALLED FOR FRAME REPLACEMENTS. WE OWN TRUCKS 30-40 YEARS OLD AND NOT ONE OF THEM HAS EVER HAD A FRAME RUST THROUGH TO THE POINT YOU CAN LITERALLY POKE HOLES IN IT WITH YOUR FINGER. THIS IS UNACCEPTABLE ON A VEHICLE 10-15 YEARS OLD. [XXX] *TR”
