Severe overheating and smoke from rear defrost window area. Same issue happened to my vehicle as described in recall number N192265660 with GM. I used remote start to warm up truck and when I went to get in and opened the rear door, smoke bellowed and a bright red glow (flame?) at the rear window was present. Due to the low temperature outside, cold air rushed in and the driver side rear window fractured from thermal shock. Appeared as a short or bad circuit caused the extreme heat in this area.
