Am experiencing a strange occurrence in my OB. Just bought it do don't know a lot about it. When shifting the auto trans into sport mode the horn sounds every time I upshift. Also when setting the cruise, mounted on the side of the steering wheel, it too beeps the horn and sets the tpms light flashing. Occasionally when setting the cruise the sport gears show up on the dash even though it's not in sport mode. Any suggestions on this stuff would be greatly appreciated n
