The 2013 FJ Cruiser with the 4.0L 1GR-FE V6 is generally robust, but a subset of engines suffer catastrophic piston failure, and the transmission cooling system has a design flaw that can destroy the transmission if ignored.
Symptoms: Cold-start piston slap that persists after warm-up, Metallic knocking noise from lower engine block, Loss of compression in one or more cylinders, Metal shavings in oil, potential bearing damage
Fix: Complete engine rebuild or short-block replacement required. 18-25 labor hours for full rebuild with machine work; 12-16 hours for short-block swap if available. This affects a minority of engines but when it happens it's catastrophic. Often blamed on insufficient piston-to-wall clearance from factory.
Estimated cost: $4,500-8,000
Transmission Oil Cooler Line Corrosion / Failure
Common · high severity
Typical onset: 60,000-120,000 mi
Symptoms: Transmission fluid leak near radiator area, Pink or milky fluid under vehicle, Transmission slipping or harsh shifts if coolant mixes with ATF, Engine overheating if coolant leaks externally
Fix: External steel cooler lines rust through where they connect to radiator or run along frame. If caught early, replace lines and flush transmission (3-4 hours). If coolant contaminates ATF, full transmission rebuild or replacement required (12-18 hours). Inspect lines annually in rust-belt states.
Symptoms: Gear oil dripping from front of rear differential, Oil coating on driveshaft behind diff, Low fluid causes whining or howling on deceleration
Fix: Pinion seal fails from age and heat cycles. Requires driveshaft removal, pinion nut torque check, seal replacement, and new crush sleeve if preload is lost. 2-3 hours labor. Check fluid level every oil change to catch early.
Estimated cost: $350-600
Transmission Mount Failure (Rear Mount)
Common · low severity
Typical onset: 80,000-140,000 mi
Symptoms: Clunk or thud when shifting from Park to Drive or Reverse, Vibration felt through floor at idle in gear, Visible cracking or separation of rubber from mount bracket
Fix: Rear transmission mount deteriorates from heat and load cycles, especially in 4WD models used off-road. Replacement takes 1.5-2 hours including crossmember drop. Inspect visually during oil changes.
Estimated cost: $250-450
Secondary Air Injection Valve Failure (P0441, P0446)
Occasional · low severity
Typical onset: 90,000-150,000 mi
Symptoms: Check engine light with evap or air injection codes, Rough cold-start idle for first 30 seconds, Hissing noise from engine bay on cold start, Emissions test failure
Fix: Air injection control valve sticks or fails, triggering evap/emissions codes. Valve replacement is straightforward but requires intake manifold access. 2-3 hours labor. Not a safety issue but will cause inspection failure in emissions-test states.
Estimated cost: $400-700
Exhaust Manifold Stud Corrosion (Rust Belt)
Occasional · medium severity
Typical onset: 80,000-140,000 mi
Symptoms: Exhaust tick or tapping noise from engine bay on cold start, Noise disappears or lessens when warm, Visible rust or exhaust soot around manifold-to-head joint, Check engine light with bank 1 or bank 2 O2 sensor codes
Fix: Manifold studs rust and break, causing exhaust leaks. If caught early, re-torque or replace accessible studs (1-2 hours per side). If studs break flush with head, requires manifold removal and drilling/helicoil (4-6 hours per side). Common in salt states.
Symptoms: Clunking over bumps at low speed, Excessive play when prying on wheel with tire off ground, Wandering or looseness in steering, Uneven inner tire wear
Fix: Lower ball joints wear faster than uppers, especially with lift kits or oversized tires. OEM design is non-serviceable; requires full lower control arm replacement per side. 2-3 hours per side with alignment. Aftermarket replaceable-ball-joint arms available.
Inspect transmission cooler lines and fittings every oil change; replace preemptively at 80k if rust-belt vehicle
Check rear diff fluid level every 10k miles; pinion seal leaks are slow but will grenade the diff if ignored
Listen for cold-start piston slap; if it doesn't go away in 10 seconds after warm-up, budget for engine work
Replace transmission mount at first sign of clunk; delays cause driveline wear
Avoid extended idle in summer traffic; 1GR-FE pistons don't tolerate sustained heat well
Buy one if you can verify no engine knock and cooler lines have been replaced; pass if any bottom-end noise or transmission issues present—repairs exceed vehicle value quickly.

Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain model year 2008-2014 FJ Cruiser and Tacoma vehicles equipped with accessory wheels and tires installed by Toyota or dealers prior to the vehicle's first sale. The affected vehicles may list incorrect spare tire size and/or cold tire inflation information on the tire placard. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard No. 110, "Tire Selection and Rims for Passenger Cars."
Consequence: If the spare tire is inflated to the incorrect pressure provided on the placard, tire failure may occur while it is being driven on, increasing the risk of a crash.
Remedy: For the involved vehicles, overlay stickers to correct the tire placard will either be mailed to owners or provided to dealers for placement over the incorrect information on the placard. The recall is expected to begin in September 2014. Owners may contact Toyota customer service at 1-800-331-4331.

Toyota Motor Corporation (Toyota) is recalling certain model year 2007-2013 FJ Cruiser vehicles manufactured January 25, 2006 through February 23, 2013 and equipped with a Toyota Auxiliary Driving Lamp Kits mounted to the front bumper. These lamp assemblies include 55 watt bulbs and due to this wattage and mounting angle, the combination of the upper beam headlamps plus the auxiliary lamps are too bright and exceed the maximum light output allowed for an upper beam headlamp. Therefore, these vehicles fail to conform to Federal Motor Vehicle Safety Standard No. 108, "Lamps, reflective devices, and associated equipment."
Consequence: Light intensities above the maximum allowable limit could cause increased glare for oncoming traffic and increase the risk of a crash.
Remedy: Toyota will notify owners, and dealers will replace the 55 watt bulbs with 35 watt bulbs, free of charge. The recall began on June 6, 2013. Owners may contact Toyota at 1-800-331-4331.

Southeast Toyota is recalling certain model year 2008 and 2010-2013 Toyota Tundra, 2010-2012 Rav4, 2012 Toyota Sequoia, 2010-2011 Toyota Corolla, 2010-2011 Toyota Camry and Camry Hybrid, 2010-2013 Toyota Highlander and Highlander Hybrid, 2010-2013 Toyota FJ Cruiser, 2011 Toyota Land Cruiser, 2010-2013 Toyota Venza, 2010-2011 Toyota 4Runner, 2010-2013 Toyota Tacoma, 2011-2012 Toyota Sienna, 2012 Toyota Prius, 2013 Scion FR-S, 2011 Scion XD, 2011 Scion XB, and 2012 Scion TC vehicles. These vehicles were sold with labels that were outside the allowable one percent of accuracy of actual weight added. Thus, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) Number 110, "Tire Selection and Rims."
Consequence: An inaccurate label could lead to owners overloading their vehicles and tires. An overloaded vehicle can result in a tire failure which may result in a vehicle crash, personal injury, or property damage.
Remedy: Southeast Toyota will notify owners and provide a corrected label with instructions concerning its installation. A small group of the affected vehicles will need additonal remedies which are still being developed. The recall began on May 28, 2013. Owners may contact Southeast Toyota at 1-800-301-6859.
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.
