Hi all. Add me to the trailer brake issue list. I just bought a 2022 1500 rst in Topeka, KS, to haul my camper with. Right out of the box, had to tow my camper 430 miles at reduced speed so I could stop safely. Over this whole trip The trailer brakes operated about 10% of the time. The other 90 I kept geeting the brakes disabled service message. Sometimes they would reset after restarting truck sometimes not. I had my son hook up to my camper with his truck and towed it, no issues. Hooked mine back on it and second time I used my brakes they were disabled. I need a vehicle that will tow my camper, this truck is useless to me. How the hell does GM get by with this. Consumer's should be informed about these issues before buying these paperweights.
Update: stopped by the local GM dealer on 1/31/22. They pulled the same code most of you guys are getting, c159c. Also did the driveway test...hooked up to camper.... using the slide controller it would occasionally flash a disable message but would clear itself. When using the brake peddle, somewhere between one and six presses I would get the disabled message and trailer brakes would shut down, until I shut off and restarted the truck.
