My X is beeping at me?

[PMPNX5]

Hi all.
I tried searching the issue first, and found a few cases of Beeping X's but none quite the same as mine.

It started a couple days ago. I was leaving a parking lot, and heard two beeps (the beeps like when you shut the ignition off, not out of the horn) then that was it. A few miles down the road it did it again right after I hit the brake. So I tapped the brake again, two more beeps. All that is odd, but it gets odder. So in addition to that the next day, not only when I hit the brake would the dash beep at me, but it was right around dusk, before I had my headlights on, and as it beep the dash lights would flash, but only with the first beep (which I assume was probably happening the whole time, just not visible during the daylight). Which brings us to yesterday, I went to the movies to see Watchmen (which was more drawn out than Titanic, but not as bad a movie as 28 days later) and when I went to get out of my X, my dash beeped, my dash blinked, and also I got the annoying sound as if I left the lights on (which I did not), and this is all with the lights off, X off, and keys out of the ignition.

Has anyone even heard of this? My dealer said they had never heard of it before, and of course when I went up there Saturday, it wouldn't do it. However once I drove 20 miles back home, it started again, and hasn't stopped since. It just doesn't make sense.... All thoughts are welcomed. Thanks!

I don't the limit feature or the memo feature, and it's a different sound than the 37 degree chime.


Cliff Notes: Everytime I hit the brakes my dash beeps at me. Now symptoms seem to be getting more and more odd. Wtf? Please Help.
