Tl* the contact owns a 2012 Volkswagen jetta. The contact stated that while driving at various speeds, the horn failed to function. The contact stated that the horn functioned intermittently. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was 35,000.
