Okay, this weird thing happens if I have my trunk open on my MX when I am packing for a trip. If I leave the trunk (rear hatch) open and go to grab some more things to pack and come back a minute or two later, the MX delivers three very loud warning beeps for no apparent reason. It's odd, because all the chimes and beeps for other things are fairly quiet, but these are really loud.... they make me jump each time it happens. Does anyone know what these beeps mean?
