The rear fuel tank mounting strap rusted in half. After filling vehicle with fuel and driving 10 miles home, I noticed the skid plate hanging down that covers the fuel tank. The plastic skid plate started to crack from the weight of the tank. The design of the skid plate to the tank allows moisture and contaminants to reside between the two, rotting the straps. Thankfully I noticed this as if I had kept driving I fear the tank would have completely fallen out of the vehicle. I ordered new straps and hardware, but during the parts search I found many owners of the Toyota FJ, all years, are having the same problem. Apparently the straps are just mild steel and were not treated with any corrosion preventative from the factory. I feel they should have been at least stainless steel. Part numbers for the straps are 77602-35050 and 77601-35110. …
Single Toyota 2010 FJ Cruiser Owner. Over the last 10/11 have been really diligent taking care of my truck, unfortunately due to what seems very poor quality steel or treatment of the frame and some parts when was build by Toyota, it has cause severe rust/rotten issue leading not only to significant safety concerns (broken gas tank straps and fuel lines) but also a significant amount of money spend treating the frame and part to prevent further corrosion that could\will eventually lead to complete failure.
My Toyota FJ Cruiser 2008 "FUEL PUMP" failed to indicate the amount of gasoline I had in the tank, the car completely stop working on the freeway while I was driving approximately at 70 MPH right in the fast lane, the car/motor just ugly shook and suddenly it stall/shut down... luckily the cars behind me were able to maneuver their cars and avoided a possible crash. I tried to start the car again and gave me some forward jumps until i got it off of the road. the gas panel indicator was still reading 1/2 filled tank but not gas inside tank...I called freeway service patrol (511) and they Offered me a gallon of gas, as i run out (they saved my day). i thought this was just one hit wonder problem but not the car has been getting me in trouble ever since now my wife drives it too, she or me assume there is still gas in the car and out of the blue i wind out carrying gas in a red gallon... …
The frame on my FJ Cruiser it literately rotting to nothing. As are most produced from 2007 - 2012 I have begged Toyota for help and a resolution like with the tundra and tacoma frame rotting issues. This is a major safety issue and someone is going to get hurt or killed. My control are in rotting away from the frame. As you can see in the picture the this is bad bad. FJ Cruiser was stationary.
I recently purchased the used 2007 Toyota FJ with 101,000 miles. During maintenance and inspection, it was found that the fuel tank straps are rusted out and need to be replaced. The rear brake lines are rusted out and need to be replaced. The frame is severely rusted out and failing at the factory welds. I was referred to submit a report and investigate filing a class action lawsuit against the manufacturer for negligence, as this is apparently a known issue. I am hoping that the will reach someone that is able to help all the owners with the same issues as this should be recalled and repaired to prevent unnecessary injury or death. This is a huge financial burden for those expecting a quality vehicle that will be safe. Failing brakes, loose gas tanks and weakened frames are recipe for disaster.
I was driving down the street after filling up my fuel tank. I drove approximately 1/2 mile when I heard a sound, felt a clunk and stopped immediately. My fuel tank was hanging down on the ground. I called AAA and requested a flatbed and to bring a strap. He did not bring a strap and when my truck arrived at the mechanic the fuel tank had completely separated from the vehicle. The other complaint I have is the rusted frame. I purchased this vehicle used. I did not notice that the tube before the rear axle which holds suspension supports to the frame were completely broken off and separated from the rusted out frame that has failed. It has been welding but the rusted frame is very difficult to weld to.
