2015 Lexus GS350

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 GS350.

Body PASSENGER CARTransmission Automatic (S8)

The 2015 Lexus GS350 is a passenger car fitted with an eight-speed automatic transmission (S8) and EPA fuel-economy ratings of 19 mpg city, 29 mpg highway, and 23 mpg combined; routine service calls for 6.6 quarts of 0W-20 engine oil. Within the 20112019 model-run complaint history, the GS350 generated 15 owner complaints and one recall, with steering cited as the most reported issue—well below the 2013 peak of 41 complaints and above the 2012 low of just one. That places the 2015 model in the more settled half of the generation: not the quietest year on record, but notably less troubled than the range’s high-water mark.

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.

The 2015 Lexus GS350 recorded 15 complaints and one recall, which is slightly lower than the 16 complaints and one recall in 2014 and well below the peak of 41 complaints and three recalls in 2013. Complaints declined steadily after 2013, falling to 3 in 2016 and remaining low through 2019, while recall activity varied but remained modest, with a single recall in 2015 matching the 2014 level and being fewer than the three recalls seen in 2011 and 2013. The data show no investigations in any year, and the federal record does not specify root causes for the complaints or recalls. Positioned in the middle of a downward trend, the 2015 model year reflects improving reliability relative to the earlier spike but does not yet reach the very low complaint levels of the later years. Consequently, if minimizing reported issues is a priority, a slightly later model (e.g., 2016‑2019) may offer a stronger track record, though the 2015 GS350 remains a reasonable option given its moderate complaint and recall counts.
