All of the sudden, out of the blue, my driver's seat wouldn't recline. Turns out the problem is that the seat base was adjusted all the way to the floor, lowest position. If you move the seat up the least amount off from the lowest sitting position, the back of the seat will recline again. The driver profile switch wouldn't move the seat... it just kept the spinning indicator going. I ended up calling Tesla and am waiting for a callback from the ranger crew to sched an appointment... alas, I don't need it... I just started fiddling with the seat and it started working. It is repeatable... lower the seat to the floor and it won't recline. Hope this saves someone the trouble of learning this like I did.
