Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 LS500H.

Transmission Automatic (AV-S10)

The 2018 Lexus LS500h hybrid routes its power through an AV-S10 automatic transmission, achieving an EPA-rated 25/33/28 mpg city/highway/combined. Sitting as a notably stable entry in the model's reliability history, this year saw only four total owner complaints and two recalls. While these figures point to a generally dependable vehicle, the wheels standing out as the top complaint area means researchers should prioritize that specific assembly in their evaluations.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the engine oil and filter every 10,000 mi; spark plugs every 60,000 mi; coolant every 50,000 mi. The big-interval services (every 50,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

Owner complaints about the 2018 Lexus LS500H dominate in one area — the wheels, 2 of 4 reports (50%), well ahead of the next concern. None of this vehicle's 2 recall campaigns target the wheels, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 1 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the wheels pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
