What Happened
Your vehicle has a part called the Generator Control Module (GCM) that helps manage the battery. In some 2012-2013 Buick LaCrosse, Regal, and 2013 Chevrolet Malibu Eco models, this module might not work correctly.
Risk if Unfixed
If this issue isn't fixed, your engine could stall while driving, and you might not be able to start the vehicle. There's also a risk of a fire in the trunk due to overheating, which could cause a burning smell, smoke, or even a fire.
Free Fix
Your GM dealer will test the GCM and replace it if necessary – all free of charge. You'll be notified when the repair is available, and you should schedule it as soon as possible to ensure your safety on the road.
