2010 Toyota FJ Cruiser Problems: 18 Known Issues

On the 2007-2012 Toyota FJ Cruiser 4.0L V6 (1GR-FE), the plastic driver footrest / dead pedal breaks away from its mounting clips and becomes a loose object in the driver footwell. In documented complaints the detached footrest slid under the pedals; in at least one NHTSA-reported case it lodged under the brake pedal and prevented the driver from depressing the brake, making it a genuine safety hazard rather than a mere annoyance.

On the 2009-2010 Toyota FJ Cruiser, 2009-2010 FJ Cruisers fitted by Southeast Toyota with accessories such as leather seat covers, seat heaters or headrest DVD systems may not have had the front passenger occupant classification system calibration tested after the modification. If the sensor is out of calibration, the passenger front airbag may not deploy, or may deploy inappropriately for the occupant's size and position. About 3,235 vehicles across 16 Toyota models.

On the 2007-2013 Toyota FJ Cruiser, on the FJ Cruiser the front seat belt retractors are mounted inside the rear-hinged access (suicide) doors, not the B-pillar. Toyota found the access door inner panel had insufficient strength: when the access doors are repeatedly and forcefully slammed over time, cracks develop in the panel around the lower retractor anchor. If the panel cracks through, the retractor can detach and the front belt will not restrain the occupant in a crash. About 209,000 FJ Cruisers (2007 through late-2013 model years) were covered.

On the 2007-2014 Toyota FJ Cruiser, fJ Cruisers develop significant frame rust in salt-belt states, especially at the rear crossmember and trailing arm mounts. The frame design has areas where water and debris collect, accelerating corrosion. Rising FJ Cruiser values make frame preservation critical.

On the 2007-2014 Toyota FJ Cruiser, the FJ Cruiser's nearly flat windshield design makes it highly susceptible to cracking from small impacts that would be deflected by more curved windshields. Owners report going through multiple windshields over the life of the vehicle. The flat angle also causes more direct stone impacts.

On the 2007-2014 Toyota FJ Cruiser 4.0L V6 (1GR-FE), the thin sheet-steel inner fender aprons in the engine bay develop bulges that eventually crack and tear, typically a 3-4 inch tear in the upper inner fender roughly 6-8 inches from the firewall on both sides. It is attributed to metal fatigue from frame/body flex combined with aprons too thin to let the body mounts work properly. It affects even garage-kept and never-off-road examples; early (2007-2008) trucks are worst and Toyota later added reinforcement.

On the 2007-2014 Toyota FJ Cruiser 4.0L V6 (1GR-FE), the side-hinged rear cargo door carries the full-size spare (and often aftermarket tire carriers, gas cans, or heavier wheels). Over time the pinch-seam spot welds on the door crack and the door sags roughly half an inch, so it no longer aligns and must be lifted to latch. Rust developing from within the tailgate compounds the problem. It is aggravated by heavy tires/wheels and violent door swings during off-road use.

On the 2007-2010 Toyota FJ Cruiser, fJ Cruisers sold through Southeast Toyota Distributors (SET) with its accessory seat heaters can have the heater element or wiring damaged as the seat cushion is compressed in normal use. The damaged copper-strand element can short circuit, overheat and burn a hole in the seat cover, with a risk of injury to the occupant. SET recalled 2007-2010 FJ Cruisers in 2014 (14V743, ~3,233 units across many models) and again in 2016 (16V396, ~7,749 units) after finding that the 2014 population had been drawn from the wrong database and missed vehicles that had the heaters. Factory Toyota seats are not the subject.

On the 2007-2012 Toyota FJ Cruiser, tRD brake kits (P/N PTR09-35070) and TRD High-Performance brake kits (P/N PTR09-35100), installed at Toyota processing centers or sold by dealers as accessories on 2007-2012 FJ Cruisers, route the outer caliper brake tube with minimal clearance to the TRD 16-inch 6-spoke alloy wheel. If balance weights are stuck in the wrong spot, they rub the tube until it is damaged and leaks brake fluid, increasing stopping distance and potentially losing front braking.

On the 2007-2014 Toyota FJ Cruiser, the rear differential breather on the FJ Cruiser is located low on the axle housing and is prone to clogging with mud and debris. When clogged, pressure builds during heating cycles and forces gear oil past the pinion seal. During water crossings, the breather can suck water into the differential as the hot housing cools rapidly, contaminating the gear oil.

On the 2007-2014 Toyota FJ Cruiser, fJ Cruiser owners report rear axle shaft oil seals leaking gear oil into the brake backing plate area, coating the inside of the dust shield, the rotor/drum-in-hat parking brake shoes and sometimes pads. A clogged differential breather pressurizes the housing and accelerates seal leaks (the breather clog itself is a separate catalog issue).

On the 2007-2014 Toyota FJ Cruiser 4.0L V6 (1GR-FE), the A750F 5-speed automatic behind the 4.0L V6 develops a distinct shudder/judder felt as a vibration typically between roughly 35-50 mph under light throttle when the torque converter clutch engages during 'Flex Lockup.' It is caused by aged/degraded Toyota WS fluid losing its friction modifier, producing a stick-slip grab of the lockup clutch; in higher-mileage cases the converter clutch itself has failed. It is frequently confused with an engine misfire because it feels identical.

On the 2007-2011 Toyota FJ Cruiser, fJ Cruisers with the 6-speed manual (RA61F, full-time 4WD) can develop a chirp, squeak or rattle from the clutch release bearing area, heard with the clutch pedal released and going away when it is depressed. Toyota issued TSB T-SB-0365-10 (Dec 2010) for 2007-2011 FJ Cruiser and 2005-2011 Tacoma 6MT, replacing the release bearing, fork support and release cylinder with revised parts. Does not apply to A750F automatics.

On the 2008-2011 Toyota FJ Cruiser, fJ Cruisers that had factory wheels and tires swapped for Toyota-authorized accessory wheels and LT tires before first sale did not have the tire pressure monitoring system recalibrated correctly, so the low-tire warning lamp does not light at the FMVSS 138 activation pressure. Toyota's 11V148 covered certain 2008-2011 FJ Cruiser, Land Cruiser, Sequoia, Tacoma and Tundra vehicles (about 22,000 in total). Owners can drive on a significantly underinflated tire without warning.

On the 2007-2014 Toyota FJ Cruiser 4.0L V6 (1GR-FE), a common age/mileage failure on the 1GR-FE Denso starter: the high-current contacts inside the starter solenoid erode or corrode, so turning the key produces a single click with no crank, often intermittently and worse when hot or after moisture/salt exposure. Repeated key cycling sometimes clears enough contamination to crank, a classic tell of worn solenoid contacts rather than a dead battery.

On the 2007-2014 Toyota FJ Cruiser, the FJ Cruiser's A/C system is prone to compressor clutch failure and evaporator core leaks. The evaporator is located behind the dashboard, making replacement extremely labor-intensive. The A/C system struggles in hot climates, especially when off-roading at low speeds.

On the 2010-2014 Toyota FJ Cruiser 4.0L V6 (1GR-FE), the 1GR-FE's secondary air injection system, used to reduce cold-start emissions, is prone to failure. Water/condensation intrusion corrodes the air pump and air switching valves, or a broken plastic impeller sheds debris into the system, triggering the check engine light and often limp mode. It is most common in cold and wet climates and can strand the vehicle in reduced-power mode.

On the 2007-2013 Toyota FJ Cruiser, recall 13V163 / D0G concerns 2007–2013 FJ Cruisers fitted with the Genuine Toyota Auxiliary Light Kit on the front bumper. Its original 55-watt lamps, used with the high beams, exceed an allowable lighting threshold and can cause glare. Toyota identified approximately 11,500 accessory kits; about 209,000 owner letters were planned to reach dealer-installed and over-the-counter installations as well. A vehicle without the kit is not involved.
