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; 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.

The 2020 Lexus GX460 lands at the quiet end of a long improvement arc for this generation. Federal complaints were heaviest in the early years—38 in 2010 and 36 in 2011—then trended downward through the decade, settling at just 8 annually in 2018 and 2019, while recalls, investigations, and TSBs also generally declined from their 2010–2014 highs. For 2020, the recorded top complaint areas total only four complaints, one each in Unknown/Other, Visibility, Service Brakes, and Back Over Prevention/Forward Collision Avoidance, alongside one crash-related complaint and zero fire complaints; the data does not specify root causes. That places 2020 near the tail of a clear maturation curve with the lowest reported complaint activity in the generation. Given the minimal federal complaints and the preceding downward trend, 2020 appears to be a strong year to buy.
