2015 Lexus IS350C

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2015 IS350C.

Body PASSENGER CARTransmission Automatic (S6)

The 2015 Lexus IS350C is a passenger car that pairs a six-speed automatic transmission with an engine requiring 6.6 quarts of 0W-20 oil to deliver EPA fuel economy of 19 city, 27 highway, and 22 combined mpg. Regarding reliability, this model year sits near the lower end of the complaint spectrum with just four total owner complaints—primarily centered on the electrical system—and a single recall. This low volume of issues positions the 2015 variant as a notably stable entry in the model's history, trailing only the 2014 model's record-low three complaints and standing far removed from the 23 complaints that marked the 2011 debut 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 5,000 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 IS350C sits at the tail end of a clear downward trend in complaints and recalls across the generation. Complaints fell from 23 in 2011 to just 3 in 2014, then hit zero in 2015—the only model year in the record with no owner complaints. Recalls also declined steadily, from seven in 2011 to two in 2015, while the number of technical service bulletins (TSBs) dropped to 173, the lowest of any year shown. The single open investigation is present across all years, but the data does not specify its cause or whether it applies specifically to the 2015 model. With zero crash or fire complaints and only four total complaint entries (each a single report in different areas), the 2015 IS350C appears to be the most refined and trouble-free year of this generation, making it a strong buy for a used luxury convertible.
