I just purchased this 2019 GMC Yukon denali. About 3 weeks after; the message "service trailer brake system" started beeping...didn't really pay bother me at 1st since I weren't planning to pull anything. Then it started doing it more frequently. Now it is constantly doing it every few days. Can't seem to get it to stop. Very annoying... any suggestions?

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.
