2018 Lexus GX460

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2018 GX460.

Body SUVTransmission Automatic (S6)

The 2018 Lexus GX460 is an SUV fitted with a six-speed automatic transmission and an engine requiring 8.2 quarts of 0W-20 oil, achieving EPA fuel economy ratings of 15/18/16 mpg city/highway/combined. With only eight owner complaints registered—concentrated in the electrical system and airbags—and two recalls, this model year falls near the minimum complaint volume for the 2010-2019 range, which spans from a high of 38 complaints in 2010 to a low of 7 in 2013. That positioning marks the 2018 GX460 as one of the more reliable years in the model's recent history.

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.

Across the GX460's 2010–2019 generation, complaints and recalls followed a clear maturation arc: early years (2010–2011) saw the highest complaint volumes (38 and 36) and the most recalls (5 and 3), while the middle years stabilized, and by the later years complaint counts settled into single digits with recalls tapering to 1–2 per year. The 2018 model year sits near the tail end of this arc, posting just 8 complaints and 2 recalls — tied for the lowest complaint count in the generation alongside 2019 — with zero open investigations, a notable drop from the single investigation carried across every prior year. Technical service bulletins also declined steadily from a peak of 271 in 2014 to 123 by 2018, indicating fewer recurring dealer-addressed issues as the platform matured. The 2018 complaint profile is notably diffuse, with no dominant failure area: Electrical/Air Bags, Suspension, Air Bags, and Power Train each appear only once, suggesting no systemic defect concentration, though two of the eight complaints did involve crashes (the data does not specify root causes). Taken together, the federal record indicates the 2018 GX460 is one of the statistically strongest years in its generation, making it a sound choice for a used buyer — just ensure the two recalls have been addressed and verify that prior crash-related complaints don't apply to the specific VIN.
