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. I'll have photos once the parts come in and I take the vehicle apart. Currently I have a floor jack holding up the tank. Also to clarify, the skid plate is mounted to the fuel tank straps. Once both straps let go, the fuel tank is coming out with the skid plate. The fuel tank is located in front of the rear axle, the vehicle would run over it's own fuel tank, at least until the engine shuts off.

THE VEHICLE WAS PARKED IN MY DRIVE WAY. SQUIRRELS CHEWED THE WIRING HARNESS CAUSING LOSS OF ABS BRAKING, STABILITY CONTROL AND LOSS OF WINDSHIELD WIPERS (DURING A RAIN). I UNDERSTAND TOYOTA USES FOOD BASED INSULATION IN THE 2010 FJ CRUISER. A NICE SOURCE OF SQUIRREL FOOD. FROM THE BARE WIRES AND SQUIRREL NESTING, IT IS A WONDER MY ENGINE COMPARTMENT DIDN'T CATCH FIRE. I BELIEVE THE SQUIRREL NEST BUILDING WAS DUE TO THE CLOSE FOOD SOURCE.

Tires were purchased April 2026. Vehicle was then driven in June 2026 for off-road use, minimal usage prior to June due to mechanical issues). A structural failure occurred on 3 new truck tires (Size: 275/60R20, DOT: 0225) within 24 hours while driving under 10 MPH on a basic off-road trail. Day 1: Rear driver tire suddenly deflated with a loud thwapping sound. The tire separated from the bead and suffered a 3-4" sidewall tear. Vehicle was at 15 PSI (standard trail pressure). 10 companion trucks ran identical terrain without issue, isolating the failure to this tire batch. Swapped to spare. Day 2: Remaining tires aired up to 20 PSI to mitigate risk. Despite higher pressure and slow speeds, the exact same failure mode recurred on the replacement tire in the same rear driver location, causing another 3-4" sidewall tear. Trail patches failed. Borrowed a spare from another vehicle. 15 minutes later, a 3rd identical failure occurred on the rear passenger tire, causing a blowout and tearing on the inside sidewall. Vehicle was stranded, requiring a 2nd borrowed spare to exit. Tires had only 300 miles of total use. Failed components include the tire sidewalls and internal casing structures. All 3 failed tires are preserved and available for material inspection. Rapid, consecutive loss of multiple tires severely compromised vehicle stability, leaving me repeatedly stranded. Had these structural failures occurred at highway speeds rather than 10 MPH, a catastrophic loss of control or rollover could have occurred. The selling dealer has explicitly refused to file a warranty claim or inspect the failed casings. No prior warning lamps, pressure alerts, or symptoms occurred before the sudden, catastrophic failures.

The truck's frame was found to be cracked / rusted through in spots. It was discovered during another attempted repair 8/17/26. Because of the split / crack in the frame, the vehicle is now not drivable as it is deemed not road worthy. This problem is known to Toyota as well as the NHTSA. The Tacomas of the same years, on which this vehicle is built (same frame, same faulty rust-proofing operation from the manufacturer), was identified and Toyota was required to address it. Why this vehicle was NOT included in the fix is a complete mystery as this problem is well-known and well-documented, far and wide (see YouTube, FJ Cruiser forums, etc., etc.). NHTSA and Toyota have really let FJ Cruiser owners down on this one.
