Toyota 4Runner owners have reported 143 problems related to suspension (under the suspension category).
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.

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. . . .
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.

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!.
I have a 1997 Toyota 4runner. I was driving down the road and my frame suddenly broke. This caused me to loose control and crash into a ditch line. I've contacted Toyota and they are not wiling to help me with a replacment frame. This frame is rusted to the point of no repair. Something needs done about this.
After buying this vehicle I was underneath vehicle to repair a axle seal leaking and found extensive frame rust on passenger rear of frame. By extensive I mean the frame was rusted completely through! I have lived in ohio all of my life and have never seen a vehicle with this mileage and of this year have such severe frame rust! after further inspection I noticed rear end housing was also severely rusted. The rust on the frame is severely perforated at point where trailing arm for the rear end attaches to the frame! I was not aware of this issue before buying vehicle but after some research have found that this is definitely a manufacturer defect of some sort! these vehicles are not safe to drive with these frames in this condition and Toyota is aware of this!.
Left side frame rotted out.

Took my 2003 Toyota 4runner in for service and to have it inspected. The service guys say they cannot inspect my truck because it has a hole in the frame of the truck. The front of my frame is severely corroded after only 160k miles and completely unsafe for the road. This truck has always been well taken care of and kept clean in the winter months. This is entirely unacceptable for a vehicle of this era and highly unsafe to drive. I am sure there are many others out there driving around not knowing their trucks are rusting away to the point the frame they are riding on is falling apart under them.
Vehicle frame is completely rusting out around the rear suspension. Trailing arm mount from axle to frame is separated from frame and vehicle is not safe to drive.
I was informed of and shown excessive frame rotting/rusting through from a mechanic. The frame looked relatively normal roughly 6 months ago. I am aware that some of their other trucks have recalls due to the same issue, and I am seeing instances of this on the internet for this vehicle.
