2023 Lexus NX450h+

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2023 NX450h+.

Transmission Automatic (AV-S6)

The 2023 Lexus NX450h+ is anchored in this reference by its AV-S6 automatic transmission and a 4.8-quart engine oil capacity specified in either 0W-16 or 0W-20 viscosity, giving service writers a clear maintenance baseline for the powertrain. Reliability data for the model year are still sparse: only one owner complaint, filed under "Unknown Or Other," has been recorded, and no recalls have been issued. That minimal incident history places the 2023 NX450h+ at the earliest, lightly documented stage of its reliability record, meaning any assessment of long-term durability should be treated as provisional until more owner experience accumulates.

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 at 120,000 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 2023 Lexus NX450h+ dominate in one area — the unknown or other, 1 of 1 reports (100%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the unknown or other 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.
