Received a message on driver information system that states service trailer brake system. When towing a trailer, the trailer brakes are inoperable and pose a safety risk in the event of a sudden brake event. GM apparently has a service bulletin published for this message which indicated a replacement of the connector in the wire harness should be performed. Although I don't tow trailers often, I should be able to rely on this feature in my vehicle. My vehicle only has 70,000 miles and this is too soon for such a part to become faulty.

Loss of power steering, loss of electronic stability control, loss of all transmission gears forward and reverse, loss of automatic headlight control, loss of instrument cluster gauges including tachometer, engine oil pressure, and engine coolant temperature, loss of heated seat functionality, loss of heating, ventilation, air conditioning, and loss of infotainment/stereo system. This problem has occurred on two occasions now, the first on 01/13/2020 and then again on 02/20/2020. The vehicle was towed in to the dealer on 01/13/2020 and was also transported to the same dealership again on 02/20/2020. A tsb was performed by the dealership when it was towed in the first time that obviously did not fix the root cause of this problem. Normally the problem will go away after a period of time and then the dealership claims that they were not able to reproduce the customer's complaint. I do have video footage of the issues I experienced on two occasion as proof.
