Randomly the dash would flash a warning of "Service Trailer Brake System" accompanied by a chime. It would not have been as annoying if it just did it once, but it would reset and throw the same code about 10 to 15 times while driving over a period of 5 minutes. The dealership would replace it for 300, but the part is easily accessible (under bed above the spare tire) and can be bought online for 30 bucks.
