2020 Lexus IS350

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2020 IS350.

Transmission Automatic (S8)

The 2020 Lexus IS350 is equipped with an automatic eight‑speed transmission and achieves EPA‑rated 20 city, 28 highway, and 23 combined mpg. Its only reported owner complaint in the latest data falls under “Unknown Or Other,” and with no recalls recorded, it aligns with a reliability pattern that has seen complaints drop to a single incident in recent years, continuing the decline from the 23 complaints recorded in 2011. This low complaint count underscores the model’s overall dependability as it enters its latest production year.

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 third-generation Lexus IS350 demonstrates a clear maturation trajectory across the federal record, with owner complaints steadily declining from 23 in 2011 to just one in 2019, while technical service bulletins dropped from 247 to 77 over that same period. For the 2020 model year specifically, federal data registers only a single complaint categorized under "Unknown Or Other," alongside zero crash-related and zero fire-related complaints, continuing the minimal complaint volume observed in 2017 through 2019. This positions the 2020 model at the culmination of the generation's reliability arc, where the platform exhibits negligible reported issues and the data specifies no root cause for the sole complaint. Given this sustained low-incidence pattern and the absence of safety-critical complaints in the federal record, the 2020 model year represents an optimal purchase point within this generation.
