2020 Lexus GS350

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2020 GS350.

Transmission Automatic (S8)

The 2020 Lexus GS350 pairs an eight-speed automatic transmission with EPA fuel economy of 20 city, 28 highway, and 23 combined mpg, continuing the GS nameplate into its later production cycle. With just five total owner complaints and a single recall on record—focused on air bags, seat belts, and forward collision avoidance—the 2020 model year sits at the quieter end of a complaint history that, across 2011 through 2019, peaked at 41 grievances in 2013 and bottomed out at one in 2012. For researchers, that makes this GS350 a mature late-cycle entry whose minimal complaint volume signals the platform's reliability has stabilized well beyond its most problematic years.

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.

Across the Lexus GS350 generation, federal complaints and technical service bulletins (TSBs) peaked in 2013 with 41 complaints and 383 TSBs, before steadily declining to just 0 complaints and 81 TSBs by 2019. The 2020 model year sits at the tail end of this downward arc, reflecting the benefits of the generation's long-term stabilizing trend. For the 2020 GS350 specifically, federal data shows 3 crash-related complaints and 0 fire complaints, with the few reported issues centered on the Electrical System and advanced safety systems like Forward Collision Avoidance, though the data does not specify root causes. Compared to the high-complaint years earlier in the generation, the 2020 model represents a matured vehicle with significantly fewer regulatory red flags. Given its position at the conclusion of a proven decline in federal issues, the 2020 Lexus GS350 is an excellent year to buy.
