Is the Lexus IS 250 engine reliable?
The reliability has been nothing short of incredible - no problems in nearly 20000 miles of driving on some pretty awful roads. No bulb failures at all! The 2.5 litre engine is well-known to burn a little oil, so I check the oil level on a weekly basis. I drive thousands of miles between top-ups, by the way.
