The 2019 Land Cruiser with its 5.7L V8 (3UR-FE) is generally bulletproof, but a small percentage suffer catastrophic engine failure due to piston/ring issues, and the transmission oil cooler is a known weak point that can lead to expensive transmission damage if not caught early.
Piston Ring Failure / Carbon Buildup Leading to Engine Knock
Rare · high severityTypical onset: 40,000-80,000 mi
Symptoms: Cold-start knock or rattle that persists for 10-30 seconds, Loss of power and rough idle, Excessive oil consumption (1 qt per 1,000 mi or worse), Check engine light with misfire codes
Fix: Complete engine rebuild or short block replacement required. 25-35 labor hours depending on shop and whether you pull engine. Toyota extended warranty covered some early cases but 2019s are largely out of goodwill period now.
Estimated cost: $8,000-15,000
Transmission Oil Cooler Line Failure / Internal Leakage
Occasional · high severityTypical onset: 60,000-120,000 mi
Symptoms: Pink or milky fluid in radiator or transmission pan, Transmission slipping or delayed engagement, Overheating transmission temp gauge, Coolant level drops without external leaks
Fix: Replace transmission oil cooler and all lines, flush transmission and cooling system. If cross-contamination occurred, transmission rebuild often required (add 18-22 hours). Preventive replacement of cooler lines around 80k recommended. 6-8 hours for cooler/lines only.
Estimated cost: $1,200-2,500 (cooler only); $5,000-8,000 (with transmission rebuild)
Transmission Mount Deterioration
Common · low severityTypical onset: 70,000-110,000 mi
Symptoms: Clunk or thud when shifting from Park to Drive/Reverse, Vibration at idle in gear, Visible cracking or separation of rubber mount
Fix: Replace transmission mount. Straightforward job but requires supporting transmission. 1.5-2.5 hours labor.
Estimated cost: $300-550
Fuel Pump Recall and Related Failures
Occasional · high severitySymptoms: No-start condition or engine stalling while driving, Rough running or hesitation under load, Check engine light with fuel trim or low pressure codes
Fix: NHTSA recall 20V-490 covers defective low-pressure fuel pump (Denso). Dealer replacement free under recall. Non-recall pump failures require tank drop and pump assembly replacement. 3-4 hours labor if not covered.
Estimated cost: $0 (recall); $800-1,400 (non-recall pump failure)
Secondary Air Injection (AIR) Pump Valve Sticking
Occasional · low severityTypical onset: 80,000-130,000 mi
Symptoms: Check engine light with P0410, P0418, or P0419 codes, Slight rough idle for first minute after cold start, Emissions test failure
Fix: Clean or replace air pump check valves and hoses. Often carbon buildup in valves. 2-3 hours labor. Preventive cleaning every 60k can avoid replacement.
Estimated cost: $400-800
Front Suspension Lower Control Arm Bushing Wear
Common · medium severityTypical onset: 90,000-140,000 mi
Symptoms: Clunking over bumps, Wandering or loose steering feel, Uneven tire wear on inside edges, Alignment won't hold
Fix: Replace lower control arms (bushings not serviceable separately on this generation). Alignment required after. 3-4 hours per side, typically do both fronts together. 6-7 hours total with alignment.
Estimated cost: $1,400-2,200 (both sides)
Buy one with documented transmission services and no signs of piston issues—most are rock-solid, but the rare engine failure is catastrophic and the trans cooler will eventually need attention.
