What should I look for in a used Lexus RX 4x4?
What are the most common problems with a used Lexus RX 4x4?
Is a used Lexus RX 4x4 reliable?
The Lexus RX reliability record is, as discussed, very strong. Lexus vehicles are among the most reliable you can buy so there are no real concerns on this front.
Look for signs of over-enthusiastic use and check all non-engine electricals, such as the touch screen and sunroof/windows. You should have no issues with the hybrid power unit, as these seem to be bulletproof, with some owners having put over half a million miles on them with no adverse effects. As a consequence of this, don't be put off by high miles on a used RX450h. People bought them from new to keep a cap on fuel bills on big journeys, so a very low mileage car should attract caution, as it might well have had a harder life as a city car. Be warned, though, Lexus parts are expensive.
