Consumer Description

Service Box appears indicating - "Trailer Brake System" with a loud BING, BING, BING Alert sound. It continues every few minutes... Please note: we aren't using a trailer... I have googled/youtube it and found that this is an issue with many owners. They indicate that the wire harness in between two of the body control modules is defective. It is known to have faulty wire connection. This is intermittent, goes for months and stops for months, and then starts up again. Starting the vehicle, while driving slow or fast, it doesn't matter.
