I can only speak from what I read, and my own experience and in the last 6-months, numerous folks have had good luck with DJI on their existing Care Refresh policies… A couple of years ago, my drone was reporting an error "3000 something..." if was under the CR back then and about a week later my drone (the one I sent in -- same serial number…) was returned, not a refurbished one.
As for the recent issue (the gimbal hesitation…), When I sent it in last June, about a week later I received an itemized repair estimate with photos of the inner workings of my drone with notations of the parts they intended to replace… So, if they had no intention of doing a repair, why disassemble the drone?
However I do agree to a point that many, probably most "repairs" are merely refurbished replacements, but not all.
