i had the same issue. 18 pro with the commander. emailed customer service and they mentioned the harnesses might have come slightly loose and to check the wire lines to ensure they're not kinked. after i did all that it still kept happening. they sent me a new one with no issues any longer.
I read somewhere that the constant reading and writing on these cards shortens the life span. I've just been buying cheapo SanDisk cards and replacing every 6 or so months
