We purchased this vehicle solely for the gas mileage that was claimed on the sticker and what the dealer said it would actually get. We were very disappointed when it got 35-40% less then what they claimed. Around the city the best we were able to achieve was 19.6 mpg when the sticker and dealer claimed it would get 31 mpg or better. We even had a factory rep from Lexus drive the car and he could not get it over 20 mpg. This car is terrible! Lexus would not stand behind it and told us that there was nothing they would do. We lost 13k selling it back to the dealer.
Have an automatic default shut off for the engine when the car is sitting idle for 10 minutes. My wife pulled into our garage on electric power, forgot to take out the key because the engine is not running, and almost killed us because the car kept starting up the engine all night long.
