The issue is with the parking brake, which doesn’t comply with federal safety requirements. The parking brake cable link isn’t to specification, and the connector may fracture when the parking brake pedal is depressed. This could lead the vehicle to move when parked, especially if parked on a hill.
Dealers will replace the cable link for the parking brake free of charge. Owners may contact Chevrolet at 800-630-2438 or the NHTSA hotline at 888-327-4236.
