2007 LEXUS ES 350

Typical onset: 80,000-150,000 mi

Symptoms: Check engine light with VVT codes (P0010, P0011, P0012, P0013), Rough idle, poor acceleration, engine knocking or ticking, Oil pressure warning light at idle when warm, Catastrophic engine seizure in severe cases

Fix: The 2GR-FE is prone to oil gelling if maintenance intervals are stretched or wrong oil is used. Once sludge blocks oil passages to VVT gears or main bearings, you're looking at complete engine teardown. Minor cases: VVT gear replacement and flush (6-8 hours). Severe: short block or full rebuild (18-30 hours). Many shops won't attempt cleaning a badly sludged motor—replacement is safer.

Estimated cost: $1,200-3,500 for VVT work; $5,500-9,000 for short block or rebuild

Typical onset: 100,000-160,000 mi

Symptoms: Pink or red fluid puddle under engine bay (passenger side), Transmission slipping or delayed engagement when fluid low, Burnt transmission fluid smell

Fix: Steel cooler lines corrode where they run along the subframe and at crimp fittings near the radiator. Leaks often start small but progress quickly. Replace both cooler lines and inspect the radiator-mounted cooler for cross-contamination. Labor is 2-3 hours due to tight access and subframe interference.

Estimated cost: $450-750

Typical onset: 90,000-140,000 mi

Symptoms: Clunk or thud when shifting from Park to Drive or Reverse, Excessive vibration at idle (especially in Drive with brake on), Engine rocking visible under throttle or braking

Fix: The front torque mount (dog bone style) and right-side transmission mount crack or tear from normal use. Both are wear items on high-mileage FWD V6 cars. Front mount replacement is 1.5 hours; transmission mount is 2-2.5 hours (requires supporting the trans and removing fasteners from above and below).

Estimated cost: $350-600 for one mount; $650-1,000 for both

Typical onset: 120,000+ mi (or earlier if sludge history)

Symptoms: Deep knocking noise from lower engine, loudest on cold start or under load, Metallic rattling that increases with RPM, Low oil pressure at idle, worsens when hot

Fix: Bearing failure is usually secondary to oil starvation from sludge or missed oil changes. Once bearings are gone, the crank journals may be scored—requiring crank machining or replacement. This means full engine disassembly, bearing and seal kit, possible crank work, plus machine shop time (20-30 labor hours total).

Estimated cost: $4,500-7,500 depending on crank condition

Typical onset: 150,000+ mi

Symptoms: Hesitation or stumble under hard acceleration, Check engine light with lean fuel trim codes (P0171, P0174), Difficulty starting after sitting (fuel pressure bleed-off)

Fix: The in-tank fuel filter (part of the pump assembly) is often neglected. Lexus doesn't specify a replacement interval, but by 150k it can restrict flow. Replacement requires dropping the fuel tank (2.5-3.5 hours). Some techs replace the entire pump assembly to avoid comebacks.

Estimated cost: $450-850 for filter sock; $650-1,100 for full pump assembly

Typical onset: 100,000-180,000 mi

Symptoms: Loud rattling or grinding on cold start (first 2-3 seconds), Check engine light with VVT timing codes, Rattle disappears once oil pressure builds

Fix: The VVT gears (cam phasers) wear or get contaminated by sludge, causing rattle until oil pressure locks them. Not immediately catastrophic but indicates oil system stress. Requires valve cover removal and gear replacement on affected bank(s). 4-6 hours per side.

Estimated cost: $800-1,400 per bank; $1,600-2,600 if both banks need work
