Ordered a Pollak plug for my trailer, we'll see if that helps. The frustrating part for me is that I pull customers' trailers frequently and I can't go changing their plugs for the one time I tow them. I also have a 2014 F-150 for my shop truck and that operates all of them properly every time. I just have to use my personal truck when that's busy, which is most of the time. The problem is so widespread and well known that GM must simply have no interest in fixing it. If Ford's 7-ways are forgiving enough to work on all trailers without special provisions, then GM should seriously consider trying a new style plug.

I've had this issue now with two new trucks. The first a 2014 Silverado 1500 and now my 2016 Sierra Denali. Any trailer I ever connected them to I constantly get the "trailer connected" message followed by "check trailer wiring". I'd love to blame the problem on trailer wiring, but the same trailers function perfectly when connected to Ford trucks and older GM's. This isn't an intermittent, works on some trailers not on others thing. Neither truck has ever cosistently operated the brakes on any trailer properly. I've never seen a recall or GM acknowledgement of the issue, just wondering if anyone has ever found any solution.
