The defect: in vehicles equipped with the base radio and OnStar, the radio software may cause the radio to lock up in the OnStar Turn-by-Turn Directions mode.
GM is unaware of any crashes, injuries or fatalities related to this condition.
The hazards: if the radio locks up, the radio display will go blank and all audio functions will cease, including vehicle chimes related to warnings for a key left in ignition and driver safety belt not in use. In addition to the vehicle chime malfunction, the radio may not turn off. This could drain the battery and possibly prevent the vehicle from starting.
Number of vehicles affected: 50,731 vehicles, of which:
- 45,785 are in the United States
- 4,568 are in Canada
The fix: GM will notify owners, and dealers will reflash the radio software.
