The car was bought used about two months ago. During my most recent drive, I never blew my horn at all. Never touched it, nothing at all. I was doing 70mph on the interstate when all of the sudden it (my horn) started going off. It scared the crap out of me because I wasn't expecting it. It did it once and I thought it was just strange. I put my hand on the horn and blew it attempting to reverse it and it stopped. It happened again, did the same thing. I took the next exit and pulled off into an apartment complex. I turned the car off. I then restarted it where it honked as soon as I turned it on. I had no choice but to drive home like this. I stayed as far away from people as I possibly could and took the 10ish mile journey home. I got a few looks from people, but I did make it home safely. The car is drivable, but it's a pain and I don't want my horn randomly going off, so I refuse to drive it for now. Hopefully I can update this later on with good news...

Update from Aug 7, 2024: Update 8/7/2024: Well, my car hasn't been blown the horn at all in the past few days that I've driven it. So, I'm not 100% sure but I'm hoping this issue fixed itself.
