On another group someone reported they stopped in at the new Grand Rapids center a couple of days ago. They said the service part of it is not open yet, however they expect it to be up and running around April 23. The gallery part is open.
That may explain why Tesla has not updated their website yet.
I drove down here yesterday to fix my 2014 Model S’ dead center display (eMMC issue). The location is still a work in progress - they were still doing some drywall work - but nice people and good service. They had a Model 3 & Y on display, and it looked like they had space for 4-6 cars in their service bays.
