2012 GMC Sierra HD Warranty

GMC covers the 2012 Sierra HD with a three-year/36,000-mile bumper-to-bumper warranty and a five-year/100,000-mile powertrain warranty. During that time, owners also get 24-hour roadside assistance and courtesy transportation while their truck is in the shop. That basic warranty is average for the class, matching the warranty coverage of Ford and Ram, but the powertrain warranty is longer than both competitors’.
