What owners wrote
I had two very serious incidents. July 8th: Horn just started blaring unprompted. Locking/unlocking doors, turning motor on, disconnecting battery did nothing to stop it. I was trying everything and as I was trying to find the correct fuse to disable (it wasn't labeled), the horn burned out and started smoldering. If the car was not in my driveway AND I wasn't home, I believe a fire would have started if I didn't pull the fuse AND douse it with water.
