2012 GMC Sierra

Complaints for the 2012 GMC Sierra cluster most visibly around two areas: dashboard cracking and electrical shutdowns. Several owners report the dashboard fracturing near the passenger-side airbag without any prior collision or airbag deployment, sometimes at relatively low mileage. The concern with these cracks is their proximity to the airbag housing, which raises questions about whether a cracked dash could interfere with airbag deployment. On the electrical side, multiple owners describe the engine cutting out unexpectedly at highway speeds, taking power steering and brakes with it before the truck can be restarted after several attempts. The electrical system complaints also include other intermittent power losses and warning lights. Structure complaints largely overlap with the dashboard cracking reports. The dashboard fracture pattern appears consistently enough across multiple reports that it stands out as one of the more common physical complaints filed for this model year.
