Fitment for this 2018 Lexus GS 350 service and repair manual is set by year, engine and trim, so the procedures inside are written around the 3.5L V6 (2GR-FKS) as Lexus built it for 2018 and around the trim you actually own, not carried over from an adjacent model year that shares the badge.

Known issues on the 2018 GS 350. Two recalls are on federal record for this model year, and both land on the same component: the gasoline fuel pump. Both were filed by Toyota Motor Engineering & Manufacturing, and the first, campaign 20V012000, names the GS 350 among the Lexus models it covers alongside a long list of Toyota vehicles. In each, the concern is the same: if the fuel pump fails, the engine can stall while driving, increasing the risk of a crash. Owners have filed one complaint for the year and Lexus has issued 35 technical service bulletins. The diagnostic and repair procedures behind the fuel delivery system those recalls point to are here.
Whether the job is tracing a stall back to fuel delivery or working a scheduled service interval, it keeps you on the OEM procedure and the specification Lexus published for the 2018 GS 350.
