Bought the RX 300 certified pre-owned with 42,000 miles. Loved the vehicle until it died at 82,000 miles. Temp gauge showed cold, but engine overheated and locked up on I-80 in Gary, IN. It was 2 weeks past the warranty. After a $200 tow charge, we were told the engine needed replaced for $10,500. Lexus gave us the engine, but it still cost $3,000 in labor. Lexus offered no explanation as to cause, and declined further help. The dealership was wonderful, however. We have also had chronic problems with dash lights. We thought Lexus was bulletproof. We won't buy another one.
