Great to hear I'm not the only one with a 2024 3500 having issues. I've pulled the same trailer everyday for 3 years with no issue. A bulb burnt out on my fender marker light and I couldn't find that bulb at any auto parts store, so I ordered a set of LED lights and installed them on the trailer. Had no issue for the first couple weeks, then rain started and BAMMM that annoying message popped up. Pulled my hair out trying to figure it out. Added dielectric grease to the plug, buffed the ball to see if it was a bad ground. No change. Finally I realized something. It only happens when my headlights are turned on (nonissue with daytime running lights)!!! It's got to be a voltage issue!!! Guess I'll be rewiring my trailer back to old school bulbs until GM gets this issue figured out!!!!
