2015 CHEVROLET SONIC; 2014 CHEVROLET SPARK; 2015 CHEVROLET SPARK
Check against the official notice below — it lists the full affected range.
General Motors is recalling certain 2014-2015 Chevrolet Spark and 2015 Chevrolet Sonic vehicles with base radio and OnStar equipped systems. The radio software can malfunction and cause the display to go blank while disabling all audio functions, which prevents important warning chimes from working.
When the radio fails, drivers will not hear alerts reminding them to buckle their seat belts or warning them if they leave the key in the ignition when exiting the vehicle. This increases the risk of injury in a crash and the risk of vehicle theft. GM will notify affected owners and dealers will update the radio software at no charge. Owners of affected vehicles should contact Chevrolet customer service at 1-800-222-1020, and can reference GM recall number 15504.

In the affected vehicles, equipped with the base radio and OnStar, the radio may lock up due to a software issue, causing the display to go blank and all audio functions to cease. Because of this, there may be no warning chimes such as the reminder to buckle the seat belt and the key being left in ignition when the driver goes to exit the vehicle. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) No. 208 "Occupant Crash Protection", and 114 "Theft Protection."
