Driver's side mirror changing position - help!
Approximately 50% of the time when I turn the vehicle on, my driver's side mirror will change from the correct position to an outward or inward position. It does this on its own and does not incorrectly adjust upwards or downwards, just to the extreme left or the extreme right. It seems to favor going extreme left but it also goes extreme right occasionally. I do have memory mirror settings equipped but this is not me using an incorrect key or having the wrong position saved. If I adjust to the correct position and reset the memory position, it still happens. If I do nothing it still happens. I do NOT use the backup setting where the mirror looks down when vehicle placed into reverse (but ironically I do use that setting on the passenger side mirror).
This started happening 3 months ago and was pretty intermittent, maybe 1 out of 8 times. Now it is happening 1 out of 2 times. I have tried to manually push the mirror around from left to right but that didn't stop it. I have used the electronic controls to move the mirror to it's extreme positions but that didn't stop it. After it happens, if I reposition the mirror to the correct position and hold the memory button it will adjust to the incorrect position again so it appears to be the vehicle is choosing a new memory position on its own.
I have NOT tried to pull the battery or do a factory reset of the settings but that might be next.

Does anyone know if there's a bulletin on this? Or experienced this issue? Or diagnosed this issue?
I'd rather not go to the stealership since I'm outside of my bumper to bumper but its starting to get on my nerves.
