Whether your 2018 Lexus IS 300 runs the turbocharged 2.0L four (8AR-FTS) or the 3.5L V6 (2GR-FKS), this service and repair manual is tied to that exact year, engine and trim, so the clearances, torque values and procedures you work to are the ones Lexus published for this car rather than an approximation pulled from an adjacent model year.

Known issues on the 2018 IS 300. One recall is on federal record for this model year, and it covers the gasoline fuel system's delivery side, specifically the fuel pump: if the fuel pump fails, the engine can stall while driving, increasing the risk of a crash. Owners have filed 9 complaints for the year and Lexus has issued 34 technical service bulletins. The diagnostic and repair procedures behind that system are here.
Diagnosing a stall back to fuel delivery, setting a torque spec on either engine or working through a scheduled service, it keeps you on the OEM procedure and the correct specification for your specific 2018 IS 300.

WHEN I ACCELERATE FROM A STOP OR WHILE MOVING ON A ROADWAY, THE ENGINE SEEMS TO STALL. I'M NOT TALKING ABOUT THE NORMAL TURBO SPOOLING STALL. IT LASTS FOR ABOUT 3 TO 5 FULL SECONDS. WHEN YOU NEED POWER TO PREVENT AN ACCIDENT, YOU CAN'T AFFORD THAT TIME LAG, AS IT COULD CAUSE YOUR DEATH. THE DEALER TOLD ME THAT LEXUS SAYS IT'S NORMAL, THEY ALL DO IT. I DON'T FEEL ANY MANUFACTURER WOULD DELIBERATELY BUILD AND SELL A VEHICLE THAT WOULD PUT THE OCCUPANTS IN DANGER OF POSSIBLE DEATH. THE DEALER P
I was driving down the highway at 70 mph and it was windy at the same time. Out of no where my sunroof window exploded shattering the glass. Luckily I usually keep the cover close.
