The horn to our van will randomly start beeping at night, waking up all our neighbours. This happens when it’s cold. We brought it in to the dealership and they couldn’t find the problem. They fully charged our battery and that seemed to do the trick but we also started parking in the garage for fear of it starting again. Sure enough, we’ve been parking outside now that it’s spring and it happened again last night since it was a colder night. Plugging in the vehicle does nothing. Anyone have this happen?
