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 Sonic recorded 114 complaints, 3 recalls, 0 investigations and 1,330 total TSB filings, with 15 crash complaints and 3 fire complaints. That complaint level is lower than the 149 complaints in 2014 and far below the 353 complaints recorded in 2012, while 2016 saw only 48 complaints. Complaints and recalls have been declining steadily since the 2012 peak, forming a clear downward arc across the generation. The 2015 year sits near the midpoint of this decline, showing reduced issues compared to earlier years but still above the post‑2016 low. Consequently, the 2015 model can be considered a good year to buy, provided it is priced reasonably for its condition.
