2010 TOYOTA FJ CRUISER Complaints

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.

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 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.

No proper rust protection causing corrosion and irreparable transmission damage.

The frame has rusted so badly it no longer is road safe and the frame needs to be replaced. Large hole in frame on front passenger side, and bad rusting all over. Mechanics said this is a known issue with FJ and Tacoma frames , and in my case the only solution is to replace the frame, which will cost (with associated work) $22K.

I have a dangerous steering issue. I tried to get my Toyota dealer to fix it, or adjust it but they said nothing was wrong. I feel they didn't want to even try. This issue has almost led to head-on collisions many times. I have replaced the tires, no help there. I had it aligned, (at dealer I purchased it from) with no improvements at all. What it does is, to stay in the center of the road I can not turn my head away from constantly adding steering input. This is an issue a big one, my car Drifts left or right but rarely goes straight when steered straight, I must constantly make adjustments to its direction. Before I replace the tires again, (the car has only 53,000 miles on it) and align it again I feel this problem must be fixed or properly adjusted to work without constant steering input to stay in my lane. I replaced tires with better than it came with, costing around $750 these are now showing bad wear after less than 20,000 miles and purchase information said I should not need to replace them for 60,000 miles. Additional information is the last 300 feet to my house is a dirt road, but it's not that bumpy and shouldn't be the reason that I can't steer it straight on asphalt.

The frame has alot of rust on metal and on welds affraid of frame failing and coming apart.

Owner of a 2010 FJ Cruiser. The amount of corrosion on the frame and components is very high for the age of the vehicle, it leads to significant safety concerns (Including gas tank straps are corroded). Toyota should rectify this issue as it seems like they did a poor job on this model to isolate against rust the frame. There should be a Recall for a re-treatment of the frame (Just like they did on the Tundra and Tacoma models).

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.

The contact owns a 2010 Toyota FJ Cruiser. The contact stated while driving at various speeds over speed bumps, the vehicle would shake abnormally and was not stable while driving. The contact stated there was no warning light illuminated. The vehicle was taken to an independent mechanic where it was diagnosed with the rear axle needing to be replaced. The vehicle was repaired. The manufacturer had not been informed of the failure. The failure mileage was approximately 66,731.
