Service schedule
All 5 of these items come from Lexus's own published schedule. Manufacturer rows link to Lexus's own schedule, Independent rows to a service shop or parts retailer's published guide.

Intervals are for normal driving; towing, short trips, extreme heat or dust shorten them. Services we could not find an interval for are left off rather than guessed.
Fluids and engines
Confirm the exact spec against the owner's manual or the label under the hood; capacities vary by engine and drivetrain.
Known problems
Problems reported for this model year, with the mileage they tend to show up at. Buying past a window is not automatically a pass - it just needs to be priced in.
