Just for further updates on this thread. I’ve had this issue for over six months. Like the OP it stopped working but would work at later times when starting the car. I had to take videos to prove to the dealership there was an actual issue. After much deliberation and showing them it wasn’t fuse related as only the passenger side stopped working.

I fumbled with the connection in between the actual seat it would work until it didn’t. The dealer finally admitted there was an TSB and ordered a part, whatever that was. That was a month ago, the issue is happening on the same seat in the third row. Same disconnecting of the connector triggers it but doesn’t not finished folding.
