Defect
On certain vehicles, a software problem could cause the rearview camera image not to display when the transmission is shifted into reverse.
Safety Risk
A rearview camera image that doesn't display could reduce a driver's ability to see behind the vehicle while backing up. This could increase the risk of a crash.
Remedy
General Motors will notify owners by mail and send a wireless over-the-air software update to eligible vehicles to update the vehicle cockpit unit (VCU) software. Alternatively, you may schedule an appointment to have the update performed at a GM dealership.
