The 2022 ES 350 shares the proven 2GR-FKS V6 and 8-speed automatic from Toyota's TNGA-K platform—generally solid, but carbon buildup on direct-injection intakes and occasional transmission cooler leaks are the main watch points. Most catastrophic engine work listed in repair databases reflects accident damage or extreme neglect, not inherent design flaws.
Intake Valve Carbon Buildup (Direct Injection)
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: rough idle when cold, hesitation on light throttle, misfires under load, reduced fuel economy
Fix: Walnut-blast cleaning of intake valves requires removing intake manifold and throttle bodies. 4-6 labor hours depending on shop access tools. Preventive catch-can installation adds 2 hours.
Estimated cost: $600-1,200
Transmission Oil Cooler Line Seepage
Occasional · medium severityTypical onset: 40,000-80,000 mi
Symptoms: small ATF puddles under engine bay, slight burnt smell after highway driving, transmission fluid level dropping between services
Fix: Cooler lines or radiator-integrated cooler develop pinhole leaks from road salt and heat cycles. Line replacement: 2-3 hours. Full cooler assembly (if integrated): 4-5 hours including coolant flush.
Estimated cost: $400-1,000
Engine Mount Degradation (Transmission Side)
Occasional · low severityTypical onset: 80,000-120,000 mi
Symptoms: clunk when shifting from Park to Drive, vibration at idle with A/C on, excessive rocking during aggressive starts
Fix: Hydraulic transmission mount fluid leaks out, loses damping. Right-side mount replacement requires support of powertrain, 2.5-3.5 hours. Often done with lower torque rod bushings.
Estimated cost: $450-750
Fuel Injector Carbon Fouling
Occasional · medium severityTypical onset: 70,000-110,000 mi
Symptoms: cylinder-specific misfire codes (P030x), long crank when hot, fuel trim out of range, failed emissions test
Fix: Direct injectors clog from pump-gas quality and PCV oil vapor. Ultrasonic cleaning works half the time; replacement often needed. 3-4 hours for full set removal, test, and reinstall or replace.
Estimated cost: $800-1,800
Water Pump Weep Hole Seepage
Rare · medium severityTypical onset: 90,000-130,000 mi
Symptoms: coolant smell after shut-down, small drips from timing cover area, slow coolant loss without external puddles
Fix: 2GR-FKS uses timing-chain-driven water pump behind front cover. Seal failure requires timing cover removal, new chain tensioners recommended. 6-7 hours labor.
Estimated cost: $1,200-1,800
Buy with confidence—this is one of the most durable powertrains Toyota builds, just budget $1,500 for walnut-blast service before 100k and stay on top of fluid changes.
