This 2014 Lexus LS 460 service and repair manual is built around one model year, one engine and one set of trims: the 4.6L V8 (1UR-FSE) exactly as Lexus specified it for 2014. Clearances, torque values and diagnostic sequences read against your car, not against a generic LS 460 stitched together from several years of data.

Known issues on the 2014 LS 460. One recall is on federal record for this model year, and it covers the gasoline fuel system on the delivery side: if the fuel pump fails, the engine can stall while driving, increasing the risk of a crash. Owners have filed 8 complaints for the year, and Lexus has issued no technical service bulletins for it. The diagnostic and repair procedures behind that fuel delivery system are here.
Testing fuel delivery, working a scheduled interval on the 1UR-FSE, or sorting out what differs between the Base, F Sport and L cars all land on the same thing: the OEM procedure and the specification Lexus published for the 2014 LS 460.
