Pressing the horn button on the steering wheel ds not sound the horn. However, pushing the lock or panic button on the key fob still makes the horn beep. So the horn itself works, but pressing on the steering wheel ds absolutely nothing. Other buttons on the steering column still work (cruise control, radio controls, etc). Only pressing the horn button dsnt work thus making me unable to alert other drivers of my presence if they are drifting toward me. This has not been evaluated by a mechanic or dealer yet as I do not have the money to do so. However, a simple search on Reddit will show you that many others are experiencing this with their Subaru Crosstreks. There were no symptoms or issues that led to this. It simply stopped working one day. And I am not someone who hits their horn very often so this is not an overuse issue. Once the horn button stopped working on the steering wheel, it has not worked since. I have not had the ability to alert drivers with my horn for over a month.
