The 2017 Land Cruiser with the 5.7L V8 is exceptionally reliable overall, but a small percentage suffer catastrophic engine failure due to excessive carbon buildup on pistons causing ring seizure and oil consumption—Toyota's known issue that can grenade an otherwise bulletproof drivetrain.
Piston Ring Carbon Seizure and Catastrophic Engine Failure
Occasional · high severity
Typical onset: 40,000-90,000 mi
Symptoms: Excessive oil consumption (1+ quart per 1,000 miles), Blue smoke from exhaust on cold start or acceleration, Loss of power and rough idle, Sudden catastrophic failure—knocking, no compression, seized pistons
Fix: This is Toyota's dirty secret on the 3UR-FE V8. Carbon deposits lock piston rings in their grooves, causing oil burning that accelerates until pistons seize or connecting rods fail. Catch it early and a carbon clean service may buy time, but once oil consumption starts, you're looking at full engine rebuild or replacement. Rebuild: 35-50 hours. Short block swap: 25-35 hours. Toyota extended warranty to 10yr/150k on some VINs but many 2017s miss the cutoff.
Estimated cost: $8,000-15,000
Transmission Oil Cooler Line Corrosion and Leaks
Common · medium severity
Typical onset: 60,000-100,000 mi
Symptoms: Transmission fluid puddles under vehicle, usually passenger side, Pink or red fluid dripping near radiator area, Low transmission fluid warning or erratic shifting if leak progresses
Fix: The steel cooler lines running to the radiator corrode from road salt and debris, especially at crimp points and bends. Lines need replacement, not patching—corrosion spreads. Typically 3-4 hours labor to drop lines, flush system, refill with ATF WS. Use OEM lines or quality aftermarket with proper corrosion coating.
Estimated cost: $600-1,200
Rear Transmission Mount Deterioration
Common · low severity
Typical onset: 70,000-120,000 mi
Symptoms: Clunk or thud when shifting from Park to Drive or Reverse, Vibration through floorboard at idle or under light acceleration, Excessive drivetrain movement visible when rocking vehicle in gear
Fix: The rubber in the rear trans mount breaks down from heat and age. This is wear-and-tear, not a defect, but it's predictable on these heavy SUVs. Replacement is straightforward—support transmission, unbolt old mount, install new. About 1.5-2 hours. Use OEM or quality polyurethane aftermarket for longevity.
Estimated cost: $300-550
Fuel Filter Clogging (Early Build Dates)
Occasional · medium severity
Typical onset: 50,000-80,000 mi
Symptoms: Hard starting or extended cranking, Loss of power under load or at highway speeds, Intermittent stalling or stumbling acceleration, Check engine light with fuel trim or pressure codes
Fix: Some early 2017s left the factory with fuel system debris or inadequate filter media. The in-tank fuel pump assembly includes a non-serviceable filter, so you're replacing the entire pump module. Tank drop required—4-5 hours labor. Toyota issued a TSB but no recall. If yours hasn't been done and you're seeing symptoms, don't wait—a starved fuel pump can fail completely.
Estimated cost: $800-1,400
Brake Actuator Accumulator Failure (if Equipped with Crawl Control/KDSS)
Rare · high severity
Symptoms: Brake warning light and multiple system warnings on dash, Loss of brake assist—pedal feels hard and requires excessive force, ABS/traction control/crawl control all disabled, Whining or grinding noise from under hood near brake master cylinder
Fix: The hydraulic brake actuator (part of the stability control system) can fail internally, losing accumulator pressure. This doesn't eliminate braking entirely but removes power assist and all electronic brake functions. Replacement requires brake system bleed and recalibration—6-8 hours. This is a low-frequency issue but catastrophic when it happens. Part alone is $2,500-3,500.
Estimated cost: $3,500-5,000
Owner tips
Monitor oil consumption religiously every 1,000 miles—catch piston ring issues early before catastrophic failure.
Use Top Tier gasoline and consider periodic fuel system cleaning to reduce carbon buildup on intake valves and pistons.
Inspect transmission cooler lines annually for corrosion if you're in the rust belt—preventive replacement at 60k saves headaches.
Change transmission fluid every 40,000-50,000 miles despite Toyota's 'lifetime' claim—the 6-speed AB60F needs fresh ATF WS.
Keep up with engine air filter changes (every 20-30k) to prevent debris ingestion that accelerates ring wear.
Buy one if the engine history is clean and oil consumption documented as normal—it's one of the most durable SUVs ever made, but the piston ring lottery is real and can cost you a five-figure engine rebuild.

AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE · 18V887000
2018-12-13
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2008-2019 Toyota Land Cruiser and Lexus LX 570 vehicles. Over time, the seat belt tension sensor wire harness may break and deactivate the front passenger air bag, knee air bag, and passenger seat-mounted side airbag.
Consequence: In the event of a crash, deactivated air bags can increase the risk of injury .
Remedy: Toyota will notify owners, and dealers will modify the front passenger seat belt assembly or replace it with an improved one, as necessary, free of charge. The recall began February 11, 2019. Owners may contact Toyota customer service at 1-888-270-9371 or Lexus customer service at 1-800-255-3987. Toyota's numbers for this recall are Lexus Interim J2L and Remedy JLL, Toyota Interim J15 and Remedy J05.
