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

Body PASSENGER CARTransmission Automatic 6-spd

The 2015 Chevrolet Impala Limited is a full‑size passenger car built on Chevrolet’s contemporary platform and equipped with a six‑speed automatic transmission that pairs with a powertrain requiring 6.0 qt of 5W‑30 engine oil. Its EPA fuel‑economy rating of 18 mpg city, 29 mpg highway and a combined 22 mpg reflects the balance of size and efficiency Chevrolet aimed for in this generation. Reliability data show the model recorded 288 owner complaints—the lowest figure within the 2014‑2016 span—though the most frequent issue cited was in the electrical system, and the year saw three recalls. As the least problematic year in its recent cycle, the 2015 Impala Limited is regarded by researchers as a relatively stable point in the model’s overall reliability trend.

From the factory this vehicle uses a BCI 34 · 600 CCA battery, OE oil filter 25206377. Note the factory engine air filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

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 Impala Limited sits at a notable low point in the generation’s complaint and recall arc, with 288 complaints and just 3 recalls, compared to 619 complaints and 12 recalls in 2014, and 786 complaints and 9 recalls in 2016. This sharp dip suggests that many issues plaguing the 2014 model were addressed, while the spike in 2016 indicates new or recurring problems later in the run. The top complaint areas for 2015—electrical system (42), steering (31), and air bags (17)—are consistent with the generation’s typical trouble spots, but the overall volume is significantly reduced, and no federal investigations were opened for this year. The data does not specify root causes for these complaints, but the absence of investigations and the low recall count imply fewer systemic defects. Given this pattern, the 2015 model year appears to be a relatively safe choice within this generation, offering a window of improved reliability before the uptick in 2016.
