My 2015 Chevrolet Silverado 2500hd is now throwing a service trailer wiring system on the dash with nothing plugged into the 7way. Brakes do work on trailer and a dinging is present when hooked up but now the issue is on the truck without trailer being hooked up.
A warning message comes on the dash telling the driver there is a issue with the trailer brakes, or wiring system. The trailer brakes become inoperable when this comes on. We have contacted gm with the issue, both at the dealer level and at the corporate level; and they insist it is a problem with our trailers. The same trailers are used with older Chevrolet trucks without incident. We have also been informed by gm that the 2015 Silverado 2500's are equipped with a more sensitive trailering system. When the connection becomes wet during inclement weather, or the truck hits a bump; and the connector loses contact momentarily the message will illuminate. Resulting in the loss of trailer brakes. This is a serious safety issue.
