I bought my track about a year ago. Within the first week of owning it. Multiple times a week, when I start it there is no sound. No radio, music, blinkers, etc. Absolutely no sound. Some of the time once I get to where im going, turn it off. Once I start it again it's back. The other times takes a couple times to hear it again. When I asked the dealership, I was told it's a known issue. 9 months later it still does it. Some weeks once or twice. Other weeks up to 10 times. I pd alot of money for my truck and yes I expect it to have no problems like this.

Pulling my 5th wheel camper and the trailer braking system goes in and out. It says, "check trailer brake wiring" and "service trailer brake". I have pulled same camper with a 2020 Chevrolet and didn't experience any issues. I have found some forums discussing that it's a GM problem with a service bulletin from GM #6379278 stating GM is working on the issue. This is a very concerning issue especially when towing over 10,000 lbs.

Brand new truck, 1st time towing through mountains of Kentucky, we kept getting "check trailer wiring", "trailer brakes disconnected" "service trailer brakes" I did research and took the truck in for service. They found nothing wrong, but said we should get an adapter and gave me the name of two. We had the camper checked as well, no issues. Many complaining on blogs about this issue and many have also been told to get an adapter. Really? why would I need a $200 adapter and the fact they already knew which two I should buy, tells me, they know its an issue with the vehicle. Pretty scary when we had to come to a stop on the freeway and we didn't have trailer brakes. Never had any issues pulling it with our 2021 silverado 1500. This is really dangerous

The integrate trailer brake control system malfunctions when a trailer equipped with solar panels is hooked up. I recently rented a newer travel trailer and kept on getting a warning that the brake control system was disengaging. Every 30-60 seconds the system would connect and the quickly disconnect. I troubleshooted by hooking up a trailer without solar and the brake controller worked as intended. I also troubleshooted with the trailer by hooking up a 2015 Ford F-350 and the trailer brakes worked as intended. This is a known issue among the 2024 Chevy 2500 and 3500 owners that have reported the same issue. Replacing the trailer control system does not fix the issue.

Truck will not stay connected to our trailer brakes. We have a 2023 Grand Design Reflexion 270BN. The truck stays connected about 30% of the time. 70% of the time we get the following warnings “Check trailer wiring” or “service trailer brakes” and the trailer brakes are disconnected. Grand design has said this is 100% on the truck side. GM needs to find an update for this dangerous problem. We almost got into two crashes on a 2000 mile trip. Multiple people are in the same situation as us.

The GM brake controller will disconnect with the trailer being pulled. You get a message on the information center that the brake controller has lost connection with the trailer or no trailer brakes are available, something to that effect. This has happened up to 5 times in one day. You never know when this will happen. Pulling a 7,000lb trailer and not knowing when you will have 'no brakes' is dangerous. I bought the truck to pull my RV trailer, now am afraid too. I brought my truck into a dealer and first was told "the issue is in the trailer". There is a bulletin saying the issue is do to 'the solar panels or solar generator', I have nether, just one lead acid battery. Then was told 'they don't know what they can do'. I've been in contact with other that have the same make, model, and year that is having the same issue ! I now have a very expensive vehicle that I can't do with what it was advertised it could do !!!
