The 2014 ES 350 is mechanically similar to the Camry V6 and shares the robust 2GR-FE engine. While generally reliable, this generation suffers from a specific carbon buildup issue and a known transmission cooler design flaw that can cause catastrophic failures if ignored.
Transmission Oil Cooler Line Failure / External Cooler Leaks
Common · high severityTypical onset: 80,000-140,000 mi
Symptoms: Transmission fluid leaking near radiator or front of vehicle, Pink/red fluid puddles under car, Transmission slipping or delayed engagement if fluid level drops, Check engine light with transmission codes
Fix: Replace external transmission oil cooler assembly and lines. Critical to catch early—running low on ATF will destroy the transmission. 3-4 hours labor including fluid flush.
Estimated cost: $800-1,400
Direct Injection Carbon Buildup on Intake Valves
Common · medium severityTypical onset: 60,000-100,000 mi
Symptoms: Rough idle especially when cold, Hesitation or stumble on acceleration, Misfires on multiple cylinders (P0300-P0306), Loss of power and fuel economy degradation
Fix: Walnut blasting intake valves requires removing intake manifold and manually cleaning each port. 6-8 hours labor for thorough service. Some shops do chemical induction cleaning as temporary band-aid (1 hour), but walnut blasting is the real fix.
Estimated cost: $600-1,200
Engine Transmission Mount Failure (Front)
Occasional · medium severityTypical onset: 90,000-150,000 mi
Symptoms: Clunking when shifting from park to drive/reverse, Excessive vibration at idle in gear, Engine movement visible when accelerating hard, Vibration felt through steering wheel
Fix: Front hydraulic motor mount collapses internally. Needs engine support while replacing mount. 2-3 hours labor.
Estimated cost: $400-700
VVT-i Actuator / Oil Control Valve Issues
Occasional · medium severityTypical onset: 100,000-180,000 mi
Symptoms: Check engine light with P0010, P0011, P0020, P0021 codes, Rough cold starts with rattling noise, Timing rattle for first few seconds after startup, Reduced power and fuel economy
Fix: Usually the oil control valve (VVT solenoid) gets clogged from sludge or poor maintenance. Clean or replace bank 1 and/or bank 2 actuators. 1-2 hours labor per bank.
Estimated cost: $300-800
Water Pump Weeping / Coolant Leaks
Occasional · medium severityTypical onset: 120,000-180,000 mi
Symptoms: Coolant smell after driving, Small puddles of pink/green coolant under front of engine, Low coolant warning light, Slight overheating in stop-and-go traffic if ignored
Fix: 2GR-FE water pump is buried behind timing cover. Requires timing cover removal, new pump, coolant flush. While in there, replace accessory belts and thermostat. 5-6 hours labor.
Estimated cost: $900-1,500
Starter Motor Failure
Occasional · medium severityTypical onset: 100,000-160,000 mi
Symptoms: Single click when turning key with no crank, Intermittent no-start (works after multiple attempts), Grinding noise during cranking, Starter works when engine is cold but fails when hot
Fix: Denso starters on these have solenoid contact wear. Located under intake manifold on V6, requires manifold removal for access. 3-4 hours labor.
Estimated cost: $600-1,000
Solid purchase if under 100k miles with documented maintenance—avoid high-mileage examples with no proof of carbon cleaning or transmission services.
