I’ve got a 2021 3500 and have the exact issue. Brakes will intermittently disconnect, running lights are all okay and towing app says all connections okay. One other interesting thing I’ve noted - when I get the brakes disconnected in dic my factory controller is dark (if u look when there’s symbol that lights up). Sent from my iPhone using Tapatalk
@wxman- you have this issue since? I’ve got a 2021 3500 and have the exact issue. Brakes will intermittently disconnect, running lights are all okay and towing app says all connections okay.

Same here with my mirrors. And those big Boys really direct a lot of light into my eyes at night. I’ve been meaning to call GM because the build sheet and their website all say they should dim but they don’t. Sent from my iPhone using Tapatalk
Do your tow mirrors dim at night when headlights are on them? Everywhere I’ve read they say the top mirrors dim at night but the ones i have don’t seem to dim. Sent from my iPhone using Tapatalk
I can confirm my tow mirrors that i ordered with my truck have everything. Cameras are built into the arms and barely noticeable. One thing that is being debated (just noticed): dimming mirrors. The website says they are but I don’t see that they are. Will have to fight that out with the dealer. Sent from my iPhone using Tapatalk
I was told by the dealer they would have cameras on them as the build sheet still had all of the surround view and the “trailer less view”. So I ordered the truck with the tow mirrors - if it doesn’t well I won’t be buying that truck. Should be getting mine in the next 2 weeks so I’ll let you know what I find out!
