Coolant loss, Pressurised coolant hoses, White smoke on startup

Buying Tips for 2009–2011 Lexus IS (XE20)

  • ✓The IS 250 automatic is the default recommendation; only buy an IS 220d if the long-run use and maintenance history are unusually convincing.
  • ✓Inspect the rear brakes closely because sticky rear calipers and corroded discs are a common age-related annoyance.
  • ✓Test the audio, navigation and all screen functions because older premium electronics are expensive to sort properly.
