2020 SLT mirrors are possesed

When I put my truck in reverse, both of my mirrors oscillate up and down for approximately 20-30 seconds and then return to normal position.  Initially it was just the passenger side, but they both do it every time.  Has anyone else had this happen?  If so, did you find a fix?

When I first purchased my truck, the driver mirror would go up and left instead of down when in reverse. I took it in and they were able to re-calibrate it. Has worked ever sense. The only thing I have noticed is if it takes me more than say 30 secs to back in the garage, they return to their normal positions.

Thanks for the reply.  Took it to the dealer and they replaced the "seat control module" and all was well for about 24 hours and then the drivers mirror started doing it again.  Last time it started with the passenger mirror and then progressed to the drivers side.  Dealer is currently scratching their heads on a solution.  I will post if and when they ever figure it out.
