Rust eat my frame into.
I have a new 4runner that I was not pleased with how it was handling. I took it into an independent wheel alignment shop to get an objective opinion. The results are included in the attached document. 10 out of 14 of the settings were out of specification. I paid to have these items fixed. My car now tracks better. Corners better and has a more stable ride. These settings were so bad I now realize that I was in car that was not as safe as it should have been. I have submitted this attachment to Toyota USA and the dealer and the only response has been they will file my complaint. I am amazed that Toyota did not consider this a manufacturing defect that they should remedy as part of a new car sale.

There is excessive rust/corrosion on the frame of the truck. The skid plates completely rusted off the truck in 2010. The transmission lines have corroded to the point they have to be replaced. The engine oil cooler and radiator supports have rusted through. The exhaust rusted off the truck in 2010 as well. Currently there is extensive corrosion on the frame of the truck and the suspension components. These issues appeared in 2010 and I have been fighting them ever since. Mechanically the truck runs great, never a problem, however the vehicle's frame is disintegrating due to corrosion.
To whom it may concern: thank you for your immediate attention to this concern. I just purchased a 1997 Toyota 4runner with 173,000 miles on it. I was made aware before buying the vehicle that there is some rust underneath and so I examined the problem and determined that it is not major and is repairable. After purchasing the vehicle, I found that the problem is quite larger than I initially assessed. I realize that this makes me responsible for a bad decision but I also think that it is important for the safety of the general public to bring these rust issues to the attention of the NHTSA with the hope that enough complaints will affect a response that will hold the manufacturer responsible. I realize that this vehicle is 15 years old and has high mileage but at the same time, I don't believe that the rotting frame is an acceptable defect in an 18 year old vehicle that was clearly very well maintained by it's original owner, and by the number of submitted and unsubmitted complaints, this is a common problem with this particular vehicle which points to a defect in manufacturing. In addition, this rotting frame problem must have started when the vehicle was much younger because the frame is rotted through in two places and it doesn't take a scientist to know that this kind of damage takes time. The main frame on my 4runner is rotted completely through in front of and behind the left rear wheel. I cannot drive the vehicle that I just bought because of the safety concerns and I'm concerned that there are less mechanically inclined persons out there who are unaware of this issue and unknowingly putting themselves and the general public at risk. Please take immediate action to hold the manufacturer accountable for this defect. Thank you.

Vehicle has 129,881 miles. Severe rust through of frame underside. Had plated & welded. New rust through holes appeared within 6 months of previous weld on same frame structure but in different locations posing imminent rust through failure in center of vehicle. Cannot pass safety inspection.
I took my vehicle in for a routine oil change recently and the technician said that I have some major rust issues on my rear axle and drivetrain. He should me when it was on the lift. He explained to me that the bolt and clip than holds the brake line down on the rear differential had rusted and broken off of the differential cover. The rear differential is now leaking gear oil. The technician advised me that it is too risky to attempt to repair as it may cause the entire differential to be damaged and the whole rear axle would need to be replaced. The technician also said that it is a risk to drive the vehicle and is possibly unsafe to keep driving. He stated that it is unknown how much longer I would be able to drive it until the rear axle ceases.

I have a 2002 Toyota 4 runner that was taken in for yearly state inspection and the technician informed that the frame is rotted through. He stated that the vehicle was unsafe to drive and a rejection sticker has been placed on the vehicle. Not sure what to do now. The vehicle still looks and runs very well, but unable to drive.

Purchased a tcuv in 2012 and live in eastern nc. Took vehicle in for diagnostic and was told that frame was severely rusted. Was not made aware when purchased. Called Toyota and awaiting a call but rep says that its out of warranty and will not assist. Vehicle can't go from fine to severe in 3 years and was certified by Toyota to be fine or "like new". Something has to be done and a recall has to be issued. This is an ongoing issues that many individuals are experiencing and a severe safety hazard should something go wrong on the freeway. No one should have to die before something gets done and it would be in poor taste for this to happen before this complaint moves from its current status to investigation by our government to protect us from companies like this.

While driving on the highway the passenger rear side of my Toyota 4runner began to move up and down and wobble making the car wander all over the road. We immediately went to the local Toyota dealer, carver Toyota of columbus in taylorsville, in. Inspecting the car on the passenger rear side we found that the rear suspension had pulled away from the frame where the frame had completely rusted leaving a big hunk out of the frame. There was extensive rusting of the frame in multiple places. The car was inspected and photographed by matt warren, service manager at carver Toyota and was determined to be undriveable. This is a well maintained vehicle which is in tip-top condition in every other respect than the rusted frame. We are very upset to lose a good car which still had a lot of value still left in it to us. We also feel that this is a very important safety issue. We were incredibly lucky that neither we nor anybody else on the highway that day were injured by this dangerous situation. And we are very concerned that this has been reported in other 4runners as well and there hasn't been a recall and these dangerous vehicles are still on the road. We are holding on to the vehicle hoping that there will be some remedy for this situation. Thank you so much for your attention.

Vehicle was stationary. While replacing exhaust system components. Found what appeared to be minor rust on the passenger (right) side rear suspension mount. Further investigation uncovered a larger area of rust along the 3 welds on the inner frame rail. Cut / ground the metal back to good metal and am in the process of patching for my yearly maine vehicle inspection. Either Toyota has built an inferior frame or the newer chemicals being used to keep the roads clear in the winter to be the cause of this rust which could cause the rear suspension to fail at this point in the frame and cause a accident.
Frame and some suspension parts are very rusted, frame has holes and is becoming unsafe to drive. Vehicle is only 13 years old, only 100100 miles. Passenger side front suspension pop's when stressed in cornering. When at idle, you can hear the vibration from rust chunks in the frame. All heat shields rusted. Skid plates on front and fuel tank so rusted must remove. Now nothing is protecting the fuel tank.
Tl- the contact owns a 2002 Toyota 4runner. The contact stated that the trailing arm on the truck prematurely deteriorated and fractured with no warning in the rear. The vehicle was towed to the contacts residence and then the vehicle was towed to a repair shop who diagnosed that the rear end housing and axle differential needed to be replaced. The manufacturer was notified of the failure and they provided no remedy. The approximate failure mileage was 64,000. Dyd.
There was no "frame rotting" selection so I just chose what I think is affected. Major scaling on the inside. Outside looks perfect. Well, it seems that the inside rotted so bad that my inner frame rail on the passenger side near the rear track arm had almost rotted through. It is soft like a sponge, but yet the factory Toyota frame paint held it together. Poking it with my finger and it all crumbled revealing quite a few holes. Hood also has a lot of little rusted parts. This didn't happen because of negligence of my part. I take good care of my cars and never had troubles like these with any other car brands.

The frame on my 2003 4runner has rusted to the point of breaking. Toyota had a recall on the tacoma of the same year for this issue and that vehicle has the same frame. As an owner of a 4runner I am upset because my vehicle costs more, but Toyota will not fix this.
In a gradual left hand turn at highway speeds the rear idler assembly arm at the frame connection separated (broke due to excessive frame rust per certified mechanic), causing dramatic body roll and a near deadly head on collision with on coming traffic. Roll over potential was also greatly increased, as needed correction was employed to avoid head on collision - which created over steer to be applied to counter balance sudden almost uncontrollable spontaneous body roll.
Frame has started rusting near welds and holes. Very poor prevention of rust by Toyota. Skid plates totally rusted out and fuzed bolts. Rear diff housing is also rusty. Car will probably fall apart in a year or two.
Bought a 2000 Toyota 4runner 3 months ago. Inspection was up and took it to get inspected. They said the frame was trashed from rust.
The dealer discovered severe rusting and a hole in the vehicle frame. The vehicle has been properly maintained and should not be rusting and creating a safety issue at these miles and vehicle age. Toyota was notified and said that there is nothing that can be done. Since these vehicles share the same frame manufacturer issues as the previous frame recalls for tundra and tacoma vehicles, Toyota should do a recall and replacement of the defective frames on the 4runners as well.
The frame on my 2003 4runner has "perforations" in it's frame rails and the front cross-member is totally rotted away. . . This has been and issue with these suvs for years. . The Toyota tacoma shares the same frame/platform as the 4runner and has had similar issues, with 1 difference Toyota has repaired many of them free of charge ,but has not extended these repairs to the 4runner. . . A $30,000 dollar 12 year old SUV shouldn't have a rotted frame. I brought the truck to a Toyota dealership and they said "front crossmember is rotted off. Only be held by frotn skid plate. Found a hole in frame rail drivers side by fuel tank. " I was then told I would be informed when a Toyota USA engineer would be able to look at it to see if they would do anything about it. I was called about a week later and told the engineer refused to look at it and would not be helping me with this matter. . I then called Toyota USA and explained what was going on (I have a case # they gave me) , they told me to expect a call from the dealership (where the SUV was purchased & where the frame was inspected) in 2 days. . That call never came. . . .
The frame is rotting out.
Upon removing and replacing my exhaust and muffler on our 2000 4runner limited I spotted a hole in my frame on the rear passenger side just before my right passenger wheel and suspension. I finished installing the new exhaust an began inspecting the frame along the length of the vehicle. While the truck is not new . . . It only had what appears to be limited surface rust to most of the framework. However , the portion that was detected was clearly rusted through and now threatens the frame integrity. I expected to keep this car for a long time and am disappointed that this might shorten my expected ownership of this vehicle.
The contact owns a 1997 Toyota 4runner. The contact received notification of NHTSA campaign number: 02v021000 (suspension), however, the dealer refused to perform the recall repair due to a rusted chassis. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 151,000.
My private mechanic informed me that my vehicle's frame was rusting and was a safety concern. He notified Toyota customer care who stated that Toyota was not responsible. Toyota has taken responsibility in the past for other vehicles with the same problem. My case # with Toyota is 1504150016. Please investigate and advise. Thank you!.
