Frame rust to an unsafe level at low miles and far before any other oxidation formed. By 120,000 miles, frame had severe rust, corroded completely through front and rear tow hook sections, lower radiator support, and large sections of main frame rails (worse towards rear near suspension mounting). Body doesn't even have the beginning of any rust/oxidation on underside or exterior, but all frame and suspension components are corroding severely at an accelerated rate. Attached images are after removing loose rust with wire wheel to see true structural damage.

This well maintained vehicle had been functioning flawlessly up to this point. Our son was on his way home and vehicle felt unstable and started to veer in both directions. He maintained control of the vehicle and was able to get home. I personally drove the vehicle upon his description and sure enough it seemed very unstable. After close examination, it was determined that the frame had separated at a location which left a drivers side rear stabilizer bar detached from the frame. The frame of the vehicle is completely deteriorating and flaking apart. The vehicle is unsafe to drive. We purchased this one owner vehicle for our son. We owned a Toyota sequoia that gave us safe reliable transportation for our family for many years and thought this 4runner would be a safe and reliable vehicle for our son to go off to college. The body and mechanics of the vehicle were very sound. Now, to find out, because of the inferior frame, the vehicle is worthless. We are out the money we paid for the vehicle and disheartened by Toyota's response that our vehicle was not part of the frame recall that was a known problem and safety issue for so many owners. This could have turned out to be a life threatening situation if he had not been able to bring the vehicle under control. We understand rust & corrosion, but this is extreme. I have owned many different brands of vehicles and have never seen anything like this. This frame is literally crumbling away leaving a beautiful vehicle to waste.

The contact owns a 2004 Toyota 4runner. The contact stated that the undercarriage of the vehicle was extremely corroded which caused the tow bar to fracture and detached from the vehicle. The vehicle was taken to an independent mechanic who confirmed the severity of the corrosion. The contact was informed of the potential for the rear wheels to detach from the vehicle due to the corrosion. The contact reached out to A-1 Toyota (50 amity rd, new haven, ct 06515, (877) 734-6467) and was informed that the vehicle was not subjected to a recall. The manufacturer was informed of the failure but provided no assistance. The vehicle was not repaired. The failure mileage was unknown.

Truck has been well cared for and has 330K miles on it. Always clean and maintained properly by myself and previous owners. Frame is showing signs of excessive rust in the front between the wheels and at almost all of the welded areas. Some areas of frame are coming off in chunks as it appears to be rotting from the inside out. This is also affecting fuel/brake likes as well as suspension components. Pictures can be sent upon request. Family has the car at the moment.

My frame is rotted out from the inside out. Front radiator support is completely rusted out. Vehicle only has 105,000 miles. Toyota should be responsible for replacing the frame. According to the petition to investigate, 4runner owners claim the frames experience excessive corrosion and the same type of frames were cited in a previous $3.4 billion class-action lawsuit. Included in the lawsuit were about 1.5 million Tacoma, Tundra and sequoia trucks, but the petitioner says the 4runner should have been included but the attorneys didn't think there were enough customer complaints. NHTSA says it couldn't identify any crashes or injuries related to rusted frames or suspensions, but owners have complained about almost losing control of the SUVS due to rusted axles and frames. Please do something about this as this is my only vehicle.

I own a 2004 Toyota 4runner with significant rust on the frame that has nearly rusted through in some areas. Through my research I determined that this has been an ongoing issue for many Toyota vehicles close to the 2004 model year. Apparently the frame was not properly coated and rust has grown on my vehicle as well as many others at a much faster rate than is typically expected. I am worried about the safety of my vehicle as a result.

Excessive frame rust. Replaced complete rear end in 2013. Told by hyannis Toyota that it was unsafe to drive because of excessive rust. The rear end is now rusted out again in 2019 and needs replacing. In April 2019 could not have suspension replaced until frame welding was completed. Additional work of cutting out rear upper trailing arm brackets and weld in place and fabricate fuel tank strap mount and weld in place. Complete frame and underside of this vehicle is completely rusted out. We had this work down because the gas tank was falling out and we could not drive this vehicle.
