2025 Chevrolet Silverado 3500

This truck was parked on a job site, on a flat parking lot over blacktop, doing a regen for the 5th time in just a few days. The truck had 4,000 miles on it. When it completed the regen, we shut the truck off. Within 15 minutes the truck was fully engulfed in flames. A fire investigator looked at it and determined the fire started in the engine bay, below the master cylinder. He said this was a GM problem. As this truck was a replacement truck, for another broken down truck, we were outside the auto coverage on our insurance. The business property is covering the tool loss, and said it isnt worth going after GM as they make it impossible. I know this isnt the only vehicle this has happened to, and they simply refuse to even answer. I want to file a formal complaint against GM, and want them to cover the loss, the loss of use. This is a safety matter as this could have happened driving down the road and caused loss of life.

We were towing our 2025 Brinkley Z3100 Fifth Wheel and had a complete loss of trailer brakes with no warning or notification during a trip to and from the tennessee mountains from Florida. Had we not noticed the poor stopping ability it would have been an issue on any downhill grades as the trailer is in excess of 14,000 lbs. We stopped disconnected and reconnected the 7 pin connector and brakes were restored. This happened 4 times. We have made an appointment with the service department at Davis Chevrolet in Gainesville Florida however the service writer (Paul) has already indicated that he feels it is a trailer problem with the interaction of the trailer. Internet searches show this is a common problem with the GM Products and a Service Bullitin has been issued for years 2023-2024. Ours is a 2025 with the identical issues. I think there could be many many more of these out there and hope the issue can be resolved. I can reproduce the problem and it meets the full description of the Service bullitin 6379278.

The trailer brake controller randomly shuts down. We have gone through our trailer meticulously and have found zero issues. We have used this trailer with other trucks without any issues. This truck brake controller is shutting down leaving the driver with out brakes. We almost had a wreck due to this. GM keeps telling us that it is a trailer issue however the trailer works perfectly with any other truck. Someone is going to die in a wreck of this is not addressed immediately.
