2015 CHEVROLET SILVERADO 3500 Electrical System Integrated Trailer Brake Control Problems

2015 CHEVY 3500 HD HAS 65,XXX MILES ON IT CURRENTLY. TRUCK PERIODICALLY AND USUALLY RANDOMLY DISPLAYS A "SERVICE TRAILER BRAKE" MESSAGE WHICH CONSTANTLY GOES OFF WHEN NOTHING IS BEING TOWED. NOW ABOUT 1 IN 15 TIMES DRIVEN WILL IT NOT DISPLAY THIS MESSAGE. IVE HAD THE TOWING BRAKE MODULE REPLACED AND THAT DID NOT FIX THIS PROBLEM. I'M AT MY WITS END WITH THIS TRUCK. CHEVROLET / GMC NEED TO STEP UP AND MAKE THIS WIDELY KNOWN PROBLEM A RECALL. THANKS
