I have another 4 runner with a heavily rusted frame. I am very concerned that a unseen failure can occur while towing a 4300 pound camer or while driving on rough roads. I'm not only concerned for my wife and I but also for our grandkids that visit us monthly. Here is the actual failure. My wife came in last Thursday and asked me what is that car part that fell off? I went out to check and found the right body mount laying there. The bolt that holds it had rotted in two between the upper and lower rubber pieces. The bolt and nut on the bottom looks good so there was no indication of a imminent failure. I'm concerned that other more serious failures can occur.

Excessive rust/rot on the frame, which is leading to expensive repairs and fears of unsafe operation.

I purchased this vehicle in 2015 with 111K miles on it. Just found out today March 2 that the frame is shot and the control arms for the rear axle have let go on both sides do to frame rot, there are also other questionable parts of the frame. So very disappointed in this Toyota vehicle. This car couldn't even last 20 years, not the reputation of what I thought Toyota were know for.

- Salem, MA, USA

Many signs of premature rust on the frame with several holes. The truck only has 124K miles and should not be in this state. Toyota has to recall these frames just like they do from other trucks manufactured during the very same years.

- Brooklyn, NY, USA

Vehicle frame has rusted completely through in certain areas - structure and safety is compromised.... normal driving & care environment but appears frame has accelerated deterioration, while all other areas (body panels, all other components) are in excellent condition - seeing this is a known Toyota issue on same models and similar models of same production years

- Libertyville, IL, USA

Premature and excessive frame corrosion. Similar models were covered by earlier frame recall, why not the 4runner?

My 2004 4runner limited V6 has significant rust build up on the frame, control arms, driveshaft, etc. I am the second owner with just over 21K miles driven in the past three year and right at 160K total. I've made sure to get regular washes to protect the undercarriage after inclement weather since I've owned the vehicle. After returning from a 10-month deployment, two shops have told me the condition is dangerous and requires significant replacement parts and anti-corrosion treatment to remedy the problem. I don't have thousands of dollars to spend on a truck that should last me at 250K miles. I will not let my wife and girls ride in this vehicle, but we need two cars. Imagine my shock to find out many other Toyota owners have dealt with the same thing. This is clearly not a coincidence. Hoping for Toyota to rectify this serious safety/quality issue.

Frame is rotted 115K miles on the car, it seems to be rotting at the welds only.

- Valhalla, NY, USA

Frame rusts too easily. Coating was not good enough from factory. Tacoma's with same frame were recalled.

I was informed that when I went to get my oil changed this morning that I had major rush on my frame it was cracked and had big holes in it and they were afraid to put it up on the lift. Advised me to check with my dealer to see if there was a recall. According to kbb there is not with my corresponding VIN number which is a dang shame because this is a safety issue and I should T be afraid to drive my grand children around in fear that my frame won't support us. We purchased this vehicle because Toyota is known for their safety, reliability.integrity and longevity. So because of the excellent feedback I have received about Toyota's ' lasting forever' I made my first Toyota purchase. The body deceived me. Other than a little golf ball dent on the front fender. The body is very good condition not a speck of visible rust.

- Hedgeville, WV, USA

The frame has rust and has a hole. It is unsafe to drive and will need to be addressed very soon. There was no specific incident. I recently bought this car. I don't know when it happened.

- Oak Brook, IL, USA

While driving the vehicle and after turning onto a state highway it suddenly swerved badly and the rear end began swaying back and forth making it uncontrollable. I stopped the car immediately. It was discovered that the frame had rusted so badly it became separated from the rear axle. I had to tow it home on a flatbed trailer.

- Norwich, VT, USA

The structural frame of the vehicle is rusted out. Holes, large areas of the frame has rusted out. The frame is structurally compromised. Just noted on 10/19/20. Vehicle was in less than a year earlier with no sign of the damage.

- Arlington Heights, IL, USA

I recently bought a used 2004 4runner and when I inspected the frame there was rust everywhere. Not only surface rust but actual holes in the frame from it. Also the steering assembly is completely rusted out. I'm not the only 4runner owner who has experienced these issues. If you do a quick online search for '4runner frame' there are many results detailing this issue. As I use this vehicle for commuting to and from work I am concerned about its structural integrity. It only has 70000 miles on it and it's completely unacceptable that Toyota has not issued a recall for this problem as they did with other models (Tacoma, Tundra, sequoia).

- Colorado Springs, CO, USA

Frame has sever rust-through and corrosion on the passenger side in front of the rear trailing link mount and behind the front control arm mount. Vehicle is driven in an environment where road salt is used in the winter, but this is excessive compared to other older vehicles. Vehicle is washed regularly in the winter.

- Sioux Falls, SD, USA

Severe frame rust on 2004 4runner SR5 sport. Suspension rust, steering components rust. Holes in vehicle frame due to rust. I went to two mechanics that told me that this rust was beyond reasonable for normal rust on frame, they both stated it may become dangerous and to contact Toyota directly. The vehicle is becoming dangerous to drive due to possibly of failing components and or frame.
