JB1676

I have a 2017 GMC Sierra SLT with rear power slider and defrost. Yesterday was very cold here in Southern Ontario. Remote started the truck before leaving work. Three to four minutes later I got in the truck and was preparing to leave work (hadn't moved yet) when I heard a loud pop. Rear window, left panel was shattered into a thousand pieces. Truck wasn't moving, no structures above and no one in sight. Only thing I could come up with is that the rear window defroster comes on automatically when remote starting in cold weather. With the outside air temp being -12C and the defroster warming up the window the temperature difference caused uneven expansion of the glass and pop goes the weasel! Price tag to replace the window is $1,000. Thank goodness insurance is looking after most of the bill. If this is an issue with these trucks GM should be issuing a recall although highly unlikely they would admit to a defective defroster. John
