Over the past few weeks, we've noticed that our Ford Escape will sound its horn in random spurts after we start the vehicle. It's not the beep from the alarm or from the lock/unlock sound, but the actual horn. It usually only does it when it's really cold though. Brand new battery.

It's normally something like.. beep.. 5 seconds.. beep.. 10 seconds.. beep.. 2 seconds.. beep.. 20 seconds.. beep.. 4 seconds.. beep.. beep beep.. 3 seconds.. beep.

There's absolutely no pattern or code to the beeping.
