The 2019 LX 570 shares the Land Cruiser's bulletproof 5.7L 3UR-FE V8 and runs the proven 8-speed transmission, but this generation suffers from a catastrophic carbon buildup defect that destroys pistons and rings, often requiring complete engine rebuilds at surprisingly low mileage.
Catastrophic Piston and Ring Carbon Failure (3UR-FE Engine)
Occasional · high severityTypical onset: 40,000-90,000 mi
Symptoms: Excessive oil consumption (1 qt per 1,000 mi or worse), Blue smoke on startup or acceleration, Misfires and rough idle, multiple P030X codes, Loss of power and engine knock in severe cases
Fix: Carbon deposits score cylinder walls and destroy piston rings; requires full engine rebuild with new pistons, rings, honing, and often crankshaft work. 40-60 hours labor depending on scope. Some owners pursue TSB warranty extensions or goodwill claims if under 100k mi.
Estimated cost: $12,000-18,000
Transmission Oil Cooler Line Leaks
Common · medium severityTypical onset: 60,000-120,000 mi
Symptoms: ATF puddles under vehicle near front crossmember, Low transmission fluid warning light, Delayed shifts or slipping when fluid level drops
Fix: Rubber hoses at cooler connections or the cooler itself crack from heat cycling. Replace lines and cooler as assembly, flush system. 2-3 hours labor.
Estimated cost: $600-1,200
Transmission Mount Failure
Occasional · low severityTypical onset: 80,000-130,000 mi
Symptoms: Clunk or thud on throttle tip-in or deceleration, Vibration at idle, especially in Drive, Visible torn rubber or separation on mount inspection
Fix: Rubber deteriorates from heat and age. Replace mount, typically the rear transmission mount. 1.5-2 hours labor.
Estimated cost: $350-600
Fuel Filter Clogging (Premium Fuel Markets)
Rare · medium severitySymptoms: Hard starting after sitting overnight, Intermittent power loss or hesitation under load, P0087 fuel pressure codes
Fix: In-tank filter and external canister filter can clog with sediment, especially if vehicle sat or got bad fuel. Replace both filters, drop tank for in-tank unit. 3-4 hours labor.
Estimated cost: $800-1,400
Head Gasket Seepage (Secondary to Carbon Buildup)
Rare · high severityTypical onset: 60,000-100,000 mi
Symptoms: Coolant loss with no visible external leaks, White smoke from exhaust, Overheating or erratic temp gauge, Milky oil or coolant in overflow tank
Fix: High cylinder pressures from carbon deposits can blow head gaskets. Both heads off, resurface, new gaskets, timing components. Often done during piston rebuild. 25-35 hours labor standalone.
Estimated cost: $5,000-8,000
Buy a 2019 only if you can confirm oil consumption history is clean or secure an extended warranty covering internal engine work—the piston failure is a financial landmine that can total the value of the truck.
