NHTSA Complaint #11586580 — 2015 CHEVROLET SILVERADO 2500

I purchased this 2015 pickup as a preowned vehicle in March of 2022. Only a few months later and 2,000 miles, the service trailer brake system warning chime activated over and over again. This happened randomly without any apparent pattern. It happened primarily when no trailer was connected. It has continued to get worse and more frequent. When it starts to chime the message and chime doesn’t just come on once it chimes over and over again for entire drives lasting hours. This problem has gotten worse by becoming more frequent. This is so bad that it is very distracting to me as the driver. It takes my attention off the road and not only that it causes me a headache from the constant annoying chime. This is very unsafe whether towing or not. It is even more dangerous when towing a vehicle as it is unknown if the trailer brake system will work in any moment of need. This malfunction can endanger the lives of people on the road.
