Selected complaints filed with NHTSA by 2007 Toyota FJ Cruiser owners, lightly cleaned up (personal details are redacted by NHTSA).
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.
Serviced 99% of the time at Toyota dealer. Within a week of having the vehicle serviced by the dealer, I noticed a rattling/banging. One gas strap had completely rusted through, and the other was hanging on by about a quarter inch of material. I always ask the dealer to inspect the frame due to the history of rust problems on FJs-they have never flagged anything but I inspect it as I can myself, but have no way to lift the vehicle up thoroughly. I also have the service fluid applied by Rust Check to prevent/inhibit deterioration. On a sidebar, this summer I was traveling on the interstate when the rear-most crossmember rusted out while I was using a hitch haul to move a dresser to South Carolina.
FJ Cruiser in Tennessee Was filling up gas tank and heard a noise under the car. I looked and noticed that the back of the gas tank was hanging down. After I got it home, I discovered that the rear fuel strap had broken due to rust. The front fuel strap was also extremely rusted and probably would have failed also
Rust is inherently bad on these vehicles. The other day i heard a weird noise under my truck driving down the road. As if I flung a rock up and hit a spring or something. To my dismay, I noticed the fuel tank hanging. One of the straps rusted to the point that it broke allowing the fuel tank to droop.
I filled up my truck with gas. Upon driving to work I noticed a loud clank. I looked under the vehicle but it was dark and saw nothing obvious. I continued down the road and heard knocking only when braking hard. When examined in daylight, I could see that the Fuel Tank Support Strap (Rear) rusted thru and the weight of the tank/fuel caused it to shift toward and rub against the Drive Shaft. The loud clank I would hear was caused by the tank being struck by the Drive Shaft balancing weight. The more I research, the more I see others have experienced the same thing. I made it safe until I could procure parts and make the repair. I examined the area and the replaced straps. The rear strap is doomed to fail. The OEM part is painted but exposed in the left rear tire well. Basically, the strap is doomed to be sandblasted by road debris, salt, sand and plain old dirt. …
The national highway traffic safety administration needs to open an investigation into reports of excessive fuel tank strap rust for the 2007 ' 2014 Toyota FJ Cruiser. This is safety problems that will most likely result in the fuel tank falling from the vehicle causing serious gasoline spilling leading to a potential explosions and/or accident. Corrosion complaints have been filed as early as 2008 and should be noted: NHTSA id number: 10257254 incident date December 17, 2008 my FJ Cruiser is stored, covered, and not driven in the winter and exhibits fuel tank strap rust above and beyond normal wear and tear. Toyota has long known of securing straps and cables that were not treated properly and yet they failed to warn new buyers or offer significant help to FJ Cruiser owners. …
I am experiencing sever rust, especially on the underside of my 2007 Toyota FJ Cruiser. This has caused the exhaust mounts to break, the loss of the skid plate which deteriorated as parts of it were trying to hang on and even my gas tank straps broke! The exhaust broke while I was driving around town for work but I was able to safely pull over and have a colleague temporarily reattach it. The skid plate happened over time until it was in pieces and had to be removed the rest of the way and the gas tank strap happened on a road trip in northern michigan and we were able to ratchet strap it back in place for the rest of the time.
I am reporting the issue of frame rust and corrosion of the fuel tank straps. The amount of corrosion and frame flaking is alarming and poses a huge safety issue for my family, other drivers and myself. Since purchasing the vehicle I have done everything I can to maintain and fix this issue including complaining to Toyota themselves with little to no success. The amount of rust compared to my other vehicle is completely out of proportion. Body mounts are flaking and crumbling and the frame is corroded and falling apart from the inside out.
Went to gas station today to fill up my FJ with gas and the fuel tank straps broke in 2 places. The bolted and pinned connections are still there but the actual straps have deteriorated and snapped right in half. The fuel tank is now hanging down completely in the rear. First the rear differential manufacturer's defect which they would not pay for at all, now the front seat belt does not work at all and now the fuel tank is about to fall off on the road. What a hazard.
