Credov's researched list of the 2 faults the Lexus RX400h is known for (2003–2008), 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 inside both headlight lenses for misting, water droplets or rust, especially just after a wash.
Why it matters: A fogged or leaking headlight lens lets water sit against the HID bulb and reflector, which can fail the low beam and cost well over a thousand dollars a side to replace, and foggy lenses mark the car down at resale.
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.
