2016 Chevrolet Silverado 2500 electrical system problems

While driving on a city street I smelled something burning I heard a sizzling sound and looked in the back and smoke was rolling from behind my passenger back seat. I realized it was coming from the wire connection for rear defroster. The smoke stopped after about 10 seconds so I continued down the road and after about 30 seconds a load boom occurred and the passenger rear section of my electric sliding window with defrost exploded. I took it to the dealer and they said it wasn't covered by warranty or recall.

Tl* the contact owns a 2016 chevrolet silverado 2500. The contact stated that the locking nut in the gear system was loose. The contact stated that the remedy should have consisted of more than just gluing; however, the failure did not recur. The manufacturer was not made aware of the failure. The contact also stated that the black fuse box underneath the hood short circuited. The contact took the vehicle to the same dealer and was informed that he was fortunate that the vehicle did not catch on fire.
