Went to do preventive maintenance and noticed my frame is rusted trough on passenger rear close to axle. There is a hole about 10-12 inches long. Very very unsafe and probably won't pass inspection. Makes me sick to my stomach. Why won't toyota fix this issue. From what i've seen it's common on this year of 4runner. *tr

The vehicles frame, in the location where the rear lower control arm bracket is welded to the frame is completely rotted out. This point on the frame secures the lower link of the rear suspension. If this bracket separates, an accident would likely occur. The rest of the vehicle is rust free and the frame is not expected to rot within the vehicles lifespan. Toyota was contacted and refused to assist wi repairs. *tr

We were a short distance from home, and were able to make our way slowly until reaching home. Upon inspection, i…

I own a 1999 toyota 4runner, the inside frame rail is almost completely rusted through near the rear trailing arm bracket . Upon investigation i've came across multiple images, websites, and forums that show the exact same problem! How is it that a manufacturer can have this much of a wide spread problem and nothing be done about it! They fixed the problem on their trucks around the same year and replaced the frames…

The frame is paper thin in numerous places. Additionally there are more locations on the rear section of the frame on the drivers side that are approaching a simular state. I have washed the truck on a regular basis and used…

The rear axle seals repeatedly fail on this vehicle, i'm now having to make a fourth costly replacement of both the rear axle seal and contaminated brake shoes. For the fourth time the rear axle seal has failed which leaks brake fluid onto rear brake shoes, resulting in severe reduction of rear braking power. Also, as a result the front brakes are placed under undue pressure and warping of front brake rotors occurs…

Frame rusted to the point where it broke. When it happened it almost caused a major accident. Left the vehicle in a condition that is very dangerous to drive. This vehicle has high miles but is in excellent condition otherwise. No rust anywhere on the vehicle except for the frame. Toyota is aware of the problem. I've seen the same problem with other 4runners. *tr
