I JUST had this exact same thing happen to me yesterday am, on my 2016 GMC Sierra Denali. Was 3F outside. 5 minutes after I started the truck, heard a "hissing" sound. Started to smell burning. Looked back and saw smoke coming from the rear window driver's passenger side. As I pulled the truck over, I saw sparks then BANG the window shattered. Looks exactly as the picture you posted! GMC Service Center told me a full week before they get back to me. I see there's a recall. When I pulled into the Dealership they blew me off. Can anyone provide the Recall Notice ID number????
