NHTSA Complaint #11670933 — 2025 CHEVROLET SILVERADO 3500

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.
