The 2012 FJ Cruiser with the 1GR-FE 4.0L V6 is generally bullet-proof, but a small percentage suffer catastrophic piston/ring failure, and the transmission cooler integrated into the radiator is a known weak point that can destroy the automatic transmission if it fails internally.
Piston Ring Land Failure / Oil Consumption
Occasional · high severity
Typical onset: 80,000-150,000 mi
Symptoms: Excessive oil consumption (1 qt per 1,000 mi or worse), Blue smoke on cold start or acceleration, Loss of power, rough idle, Metallic knock if ringland has fractured
Fix: The 1GR-FE can crack the top ringland on pistons, especially cylinders 2 and 5. Often requires complete engine rebuild or short-block replacement. 25-35 labor hours for rebuild, 18-22 for short block swap. Some cases covered under TSB but most are out of warranty by now.
Symptoms: Pink milkshake appearance in transmission fluid, Transmission slipping, delayed engagement, Coolant level dropping with no external leaks, Transmission overheating
Fix: Internal failure of the transmission cooler built into the radiator allows coolant and ATF to mix. Requires radiator replacement, full transmission flush, often torque converter and internal transmission damage. Best practice: replace radiator preventatively and install external trans cooler. Radiator replacement is 3-4 hours; if trans is damaged, add 12-18 hours for rebuild.
Estimated cost: $800-1,200 preventative; $3,500-5,500 if transmission damaged
Transmission Mount Failure
Common · medium severity
Typical onset: 80,000-130,000 mi
Symptoms: Clunk or thud when shifting from Park to Drive/Reverse, Vibration at idle, especially in Drive, Visible sag or torn rubber on mount inspection
Fix: The rear transmission mount collapses due to the weight of the A750F transmission and off-road abuse. Replacement is straightforward: 1.5-2 hours labor. Use OEM Toyota mount, aftermarket polyurethane bushings can transmit too much NVH.
Estimated cost: $250-400
Exhaust Manifold Gasket / Stud Failure
Occasional · medium severity
Typical onset: 90,000-140,000 mi
Symptoms: Ticking or tapping noise on cold start that fades when warm, Exhaust smell in cabin, Check engine light with Bank 1 or Bank 2 lean codes
Fix: The rear (firewall-side) manifold studs corrode and break, or gasket fails. Rear bank is a nightmare—requires removing intake, coil packs, and working blind. 8-10 hours labor. Front bank is 4-5 hours. Often both banks done at once. Use anti-seize on new studs.
Estimated cost: $1,200-2,200 depending on one or both banks
Secondary Air Injection (AIR) System Faults
Occasional · low severity
Typical onset: 80,000-120,000 mi
Symptoms: Check engine light: P0410, P0418, P2440, P2442, Rapid clicking from engine bay on cold start, No drivability issues, emissions test failure
Fix: AIR pump, one-way valves, or solenoids fail. System only runs first 60-90 seconds on cold start for emissions. Can replace pump (2 hours) or valves (3-4 hours) individually, or delete system if not in emissions-tested area. Many owners remove and block off.
Estimated cost: $600-1,200 for pump/valves; $200-400 for delete kit + labor
Front Lower Ball Joint Wear
Common · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Clunking over bumps, Wandering steering, loose feel, Excessive play in wheel when lifted and checked, Tire wear on inside edge
Fix: Lower ball joints wear faster than most Toyotas, especially with larger tires or off-road use. Cannot be replaced separately—requires full lower control arm. 2.5-3 hours per side including alignment. Do both sides at once.
Estimated cost: $800-1,200 for both sides
Rear Hatch Door Handle / Lock Actuator Failure
Common · low severity
Symptoms: Rear door won't unlock or open from outside, Handle feels loose or floppy, Door opens from inside but not outside
Fix: Plastic components in exterior handle assembly break, or lock actuator fails. Requires hatch panel removal and handle assembly replacement. 1.5-2 hours labor. Very common failure, keep WD-40 Lithium spray on the mechanism as preventative.
Estimated cost: $350-550
Owner tips
Replace the radiator and install an external transmission cooler by 100k miles—cheap insurance against $5k trans failure
Monitor oil consumption closely; anything over 1 qt per 3,000 mi is a red flag for ringland issues
Use OEM Toyota ATF WS—transmission is sensitive to off-brand fluid
Check transmission mount annually if you off-road; it's a wear item on this platform
Keep hatch handle lubricated and don't slam the rear door—handle assembly is fragile
Buy it if the engine doesn't burn oil and the transmission fluid is clean red—avoid any with pink ATF or high consumption; these two issues aside, it's one of the toughest modern Toyotas.

SEAT BELTS:FRONT:ANCHORAGE · 13V098000
2013-03-15
Toyota is recalling certain model year 2007 through 2013 FJ Cruiser passenger vehicles. The retractors for the front driver and passenger seat belts are mounted in the access door (rear door) panels of the vehicle. Due to insufficient strength of the access door panel, cracks may develop in the panel if the access door is repeatedly and forcefully closed over an extended period of time.
Consequence: If cracks occur in the panel around the lower retractor anchor, the seat belt retractor could become detached, which could increase the risk of injury to an occupant in the event of a crash.
Remedy: The safety recall began on June 6, 2013. Toyota will mail an interim letter to owners late in April 2013. Remedy notifications to the owners for the repair will begin in late May 2013. Owners may contact Toyota at 1-800-331-4331.

Toyota is recalling certain Toyota Racing Development (TRD) brake kits, P/N PTR09-35070, and TRD High-Performance brake kits, P/N PTR09-35100, installed by Toyota vehicle processing centers and sold by Toyota dealers as an optional accessory for model year 2007 through 2012 Toyota FJ Cruiser vehicles. The subject TRD brake kit is specifically designed for the front wheels of 2007-2012 model year FJ Cruiser vehicles. Due to the shape of the outer brake tube of the brake kit, the clearance between the outer brake tube and a TRD 16 inch 6-spoke alloy wheel is minimal. If wheel balance weights are installed in an incorrect location, there is a possibility that the outer brake tube could be damaged due to interference with the balance weight, and brake fluid could leak from the damaged tube.
Consequence: If a brake tube becomes damaged and leaks fluid, it may result in increased stopping distances, and in some cases, loss of vehicle front braking performance, which could increase the risk of a crash.
Remedy: All known owners of 2007-2012 model year FJ Cruiser vehicles will be notified by first class mail. If the vehicle is equipped with one of the TRD brake kits, the brake caliper outer brake tube will be replaced with a newly designed one at no charge. During this service, if necessary, the dealer will make wheel balance adjustments. This remedy will be performed even if the vehicle has original equipment 16 inch or 17 inch wheels or TRD 16 inch Beadlock ring type wheels, which are not affected by the condition, to assure sufficient clearance in the event wheels are changed at a later time. Notification to owners began on December 17, 2012. Owners may contact Toyota Customer Experience Center at 1-800-331-4331.
