Should be a piece of take. Others on this forum have taken apart the center console area with no issues so I think your dealership should be able to do it in an hour or two.
Main issue is waiting on parts, like any dealer visit on any other car.
2017 Summit White Bolt LT, VIN #83351, built 8/2017 (real range anxiety now).
2017 Kinetic Blue Volt LT, VIN #11925, built 6/2016. (loved it, only fake range anxiety, but traded due to annoying misfires)
