2015 Chevrolet SS

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

Body PASSENGER CARTransmission Automatic (variable gear ratios)

The 2015 Chevrolet SS is a passenger car equipped with an 8.0-quart engine oil capacity, 5W-30 viscosity, and an automatic transmission with variable gear ratios, returning EPA fuel economy of 24 city, 26 highway, and 25 combined mpg. As the second year of the 2014–2017 run, it logged 17 total owner complaints and seven recalls, with steering accounting for the most-cited trouble area. Positioned between the trouble-plagued 2014 launch—where complaints peaked at 51—and the markedly quieter 2017 model year with just seven, the 2015 SS represents an early but unfinished stage of the nameplate's reliability trajectory.

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 Chevrolet SS marks a significant improvement over the launch-year 2014 model, with complaints dropping sharply from 51 to 17 and investigations falling from 1 to 0. However, the recall count remains at 7, identical to the 2016 model, suggesting that certain systemic issues carried forward from the first year. The top complaint area for 2015 is steering, with 6 reports, though the data does not specify a root cause. Within the generation’s overall trend of declining complaints and TSBs—from 1,414 in 2014 to 899 in 2017—the 2015 sits in a favorable mid-cycle position, but it does not match the clean record of the final 2017 model year, which had zero recalls and only 7 complaints. For a buyer seeking a balance of lower complaint volume and likely availability, the 2015 is a solid choice, though those prioritizing the fewest reported issues should target a 2017.
