Credov's researched list of the 2 faults the Lexus ES350 is known for (2003–2009), 1 of them serious or costly. Each one says what to look for when you check the car, so you can spot it before you buy. Not every car has these faults: they are the ones worth checking on this model.
What to look for: Look for a rubber (not metal) oil hose near the timing cover and fresh oil below it.
Why it matters: Lexus states the rubber portion of the oil supply hose for the VVT-i actuator may degrade over time and leak, giving abnormal engine noise and an oil pressure warning light. Sudden loss of oil pressure on a V6 is an engine-ending event, so the state of this hose is worth confirming before you buy.

What to look for: Feel the dash top and door tops for tackiness, and look for a shiny glare or cracks near the airbag seam.
Why it matters: Lexus USA ran a warranty enhancement program covering this condition on these model years. A degraded dash causes windscreen glare and is an every-day irritant to the next owner, and a dashboard replacement is a large labour job that the sale price has to absorb.
