- Risk
- Without audible indicators, the driver may not fasten their seatbelt, increasing the risk of injury during a crash.
- Fix

Equipment › Electrical › Radio/Tape Deck/Cd Etc. · Jun 30, 2015
NHTSA campaign 15V416000 · 45,785 vehicles
- Problem
- General Motors LLC (GM) is recalling certain model year 2014-2015 Chevrolet Spark vehicles manufactured April 30, 2014, to May 20, 2015, and 2015 Chevrolet Sonic vehicles manufactured June 18, 2014, to June 10, 2015. 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."
- Risk
- Without audible indicators, the driver may leave the key in the ignition, increasing the risk of theft. If a driver or front passenger does not buckle their seat belt, there would be no chime to remind them to fasten their seat belts. If a driver or passenger does not buckle their seat belt there is an increased risk that they will be injured in a crash.
- Fix
- GM will notify owners, and dealers will update the radio software, free of charge. The recall began on August 11, 2015. Owners may contact Chevrolet customer service at 1-800-222-1020. GM's number for this recall is 15504.
