Approximately 2 weeks ago my bighorn decided that it believes I now have a trailer attached to it (I do not). When I have my turn signal activated and lay onto the brakes, it'll chime a warning stating that I have a trailer light out. Then it will say to check trailer connection. The trailer symbol will come on and my dash will throw a few warnings regarding checking lights and switch back and forth from auto length to 30' blind spot monitoring. It eventually clears but will happen all over again once I signal while on the brakes. If just braking or just signaling by itself, no issues. Anyone else experience this? Bighorn SST with 4700 miles over about 7 months, no tow package or trailer brake controller. Truck was basically flawless up until this.
I did tow my ATV trailer about a 6 weeks ago for a few hours and it does have a bad light FWIWI know your not the only one guilty of this so this is for everyone who "Hijacked" this thread and took it waaaayyyy off topic. This helps no one, to sift through 77 pages of crap..because you people cant start your own thread about an entirely different issue. Many of us just want to learn what we need to do regarding the Trailer Brake Controller install so that we can get it handled. But instead, the info is likely buried in all this BS.
