Hey all, I believe I have an actual fix. Before I couldn't get 30 miles without issues. I just got done trailering over 1k without a hiccup ( knock on wood). When I installed my 5er setup I installed a curt OEM in bed plug. If you're familiar these are plug and play and allow you to use your factory bumper plug still as well. My dealer was adamant it was the plug and wanted $200 bucks and another $50 to install. We made a deal that I would pay 1/2 and if it didn't work I'd be refunded. Well a factory GM 5er wiring harness has thus far worked. I was sceptical because it looked identical to the curt plug but is actually made by pollak. I also did a side by side comparison and the pollak receives the trailer plug much tighter than curt. The curt is actually sloppy. I hope this helps as I had all the same stabilitrac, service trailer brake ABS and ultimately loosing trailer braking and so far so good. Take care.

Thanks for the input. All I can do is keep in them with some gentle firm pressure. The sad thing is I love this truck, but I really bought it for 1 reason……. to tow. I will update if I find anything out further. Thanks

Hi Guys, I'm brand spankin' new to this site and only because I've been pulling my hair out for the last month. My issues are identical to what's on this thread. Service Stabilitrak, Service Trailer Brake warnings together regularly when towing with the "occasional" 70% of the time ABS which disables the trailer brakes to my 16K loaded fifth wheel! Been to the dealer now 5 times for this issue and dealer is telling me that my in bed 7 way is bad and when they disconnected it they found corrosion. I told them to leave it because I wanted to inspect this corrosion on my 1 month old 7 way that hasn't seen rain or even a car wash yet. Was told the tech cleaned it for me. HAHA! I looked at the damn thing and its brand new and still had the streaks where the dielectric grease was rubbed on terminals from its one and only connection. Has anyone gotten a fix yet. Truck is a 16 GMC 2500HD Dmax crew cab long bed. I appreciate any feedback I can get.
