Doors unlocking at 'random' in the middle of the night?

I purchased my bz4x on Dec 9th of this year. I would say approximately 5 times over the last three weeks I will wake up in the morning to see that my app indicates that multiple car doors are unlocked. I live in a sketchy area and this is not ideal.

I notice that the timing always aligns with when the battery is completed with charging at home. (Of course this is usually at 3am and I'm not awake to check).

Has anyone had similar experiences? Have you found a fix?
