The other day approximately 5 minutes after leaving my house I noticed a smell and saw some slight smoke coming from my rear window. I immediately turned off the rear defrost and my rear window shattered. The next day I discovered other chevy/GMC vehicles have a recall for a short circuit in the rear defrost. Unfortunately the dealership will not help me until there is a recall with my VIN as there is not an open recall on my vehicle.

Approximately Nov 15, 2024 is when the issue started. At approximately 44,000 miles the truck experienced a catastrophic oil coolant failure causing oil and coolant to mix. It is available for inspection. The incident happened suddenly as the truck was being driven. When pressing on the accelerator, the truck hesitated to move on several occasions. The issue was confirmed by an authorized GMC service center. The truck has been inspected by the authorized GMC service department. The warning light came on after the damage was done. There was no other sign of an issue. It wasn't until the next day when the truck was started, that the warning light appeared. No leaks of any kind.
