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 represents a mid-cycle refresh within its tenth generation, positioned between the launch-year spike in 2014 (630 complaints, 12 recalls) and the subsequent decline in 2016 (110 complaints, 0 recalls). Complaints dropped sharply from 2014 to 2015 (298 total), while recalls fell from 12 to 3, signaling improved reliability or resolved early-production issues. However, the 2015 model still exhibits elevated electrical system (43 complaints) and steering (34 complaints) concerns, though these are less severe than the broader trend in 2014. The absence of investigations in 2015 suggests no systemic defects were flagged, contrasting with the two investigations in 2014. With fire-related complaints (11) and crash complaints (10) remaining modest, the 2015 Impala appears to be a relatively stable choice—avoiding the extremes of its predecessor while benefiting from mid-cycle refinements. **Takeaway: The 2015 Impala is a prudent used buy, offering a balance of lower complaints and recalls compared to 2014, without the higher-mileage risks of later model years.**
