Fitment comes first here: this service and repair manual is matched to the 2018 Lexus IS 350 as it was built, down to the 3.5L V6 (2GR-FKS) under the hood and the trim it left the assembly line in, so the specifications and procedures you work from are the ones Lexus published for this year rather than figures carried over from an adjacent one.
Engines
- 3.5L V6 GAS Naturally Aspirated

Known issues on the 2018 IS 350. One recall is on federal record for this model year, and it sits in the gasoline fuel system on the delivery side, at the fuel pump: if the fuel pump fails, the engine can stall while driving, increasing the risk of a crash. Owners have filed no complaints with NHTSA for the year, but Lexus has issued 37 technical service bulletins. The diagnostic and repair procedures behind that fuel delivery system, and behind the systems those bulletins address, are here.
From tracing a stall back to fuel delivery to a scheduled service on an F Sport, it keeps you on the OEM procedure and the correct specification for this 2018 IS 350.
