Which IS is it?

EPA figures for each version of the 2023 Lexus IS. Use them to confirm you are looking at the version that was advertised, and as a yardstick on the test drive.

Version	Drive	EPA rating
2.0L 4-cyl	RWD	25 mpg
3.5L 6-cyl	AWD, RWD	22–23 mpg
5.0L 8-cyl	RWD	20 mpg

The 2023 Lexus IS was sold in three versions. Confirm which one this is from the window sticker, the engine cover, or the VIN report before you compare prices.
Reset the trip computer at the start of the drive. A IS that averages well under the EPA 20 mpg combined on a mixed route may have an engine or tire problem.

Check the odometer against these mileages

Owners report these failures starting around the mileages below. A car inside one of these ranges deserves a closer look at that part, or records showing it was already fixed.
