On a small number of vehicles, the windshield may not be attached properly. As a result, the glass can become loose and could separate from the vehicle.
Safety Risk
A windshield that detaches in a crash could create an increased risk of injury. Additionally, a windshield that detaches from a moving vehicle could create a road hazard for others and increase the risk of a crash.
Corrective Action
General Motors will notify owners by mail and advise you to take your vehicle to a dealership to inspect, and if necessary, remove and reinstall the windshield. If the windshield is damaged, it will be replaced.
