I got home about 7pm and parked and locked the car as usual. Around midnight (i.e., 5 hours later), the horn just started blaring and I had trouble getting it to stop. I tried starting the car, hitting the panic button, hitting other buttons, etc. What eventually seemed to work was opening/closing the lift gate. I'm going to see about getting the fuse and relay checked, but wanted to check here to see if anyone else has ever experienced this and how it was resolved.
