2025 CHEVROLET SILVERADO 3500 Complaints and Recall Information
The 2025 CHEVROLET SILVERADO 3500 has 6 complaints and 0 recalls filed with NHTSA. Owners most frequently report issues with the trailer brake system cutting out unexpectedly and problems with the electronic tailgate unlatching on its own. Other reports include roof flex noise and valve body failure affecting vehicle operation.
Common Issues
- Electronic tailgate unlatching. The tailgate opens by itself approximately every 30 seconds while the vehicle is parked, causing battery drain and potential safety hazards for pedestrians or bystanders behind the truck.
- Trailer brake controller failure. The brake controller shuts down without warning during towing, causing temporary loss of trailer brakes and increasing the risk of accidents. Disconnecting and reconnecting the 7-pin connector temporarily restores brake function.
- Trailer brake response disputed. Dealers have attributed brake failures to trailer issues despite trailers working fine with other trucks, and owners report the problem matches descriptions in a service bulletin for previous model years.
- Roof flex noises. Loud banging or movement of roof lining occurs during car wash cycles and when driving over pavement joints or bridges, particularly on models with sunroofs. Dealers have verified the issue but GM has not acknowledged or provided repairs.
- Valve body failure. A vehicle with 37,000 miles developed valve body failure resulting in disengaged engine brake, check engine light activation, trailer braking disablement, and inability to shift beyond first gear. Replacement parts are on order with no estimated delivery.
Owners dealing with repeated repairs or unresolved issues involving critical safety components such as brakes or electrical systems may have rights under their state’s lemon law. Consulting a consumer protection attorney specializing in vehicle defects is advisable to understand possible remedies.

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.

The tailgate is unlatching itself (electronically). This occurs every 30 seconds when the vehicle is parked. This is a safety issue because if someone is standing or walking behind the vehicle, the tailgate will open and injure them. Because the lights activate when the tailgate unlatches, the battery was drained and the vehicle could not start. Thus damaging the life of the battery. This has occurred consistently for the last 2 days. The dealer has the part for the issue because the 2024 has a recall but 2025 (ours) does not. Please be advised, the drained and dead battery had left us stranded.
