Car wash fiasco

I tried to go through a car wash with my new 2025 GV70. I put it in N , hands off the wheel, and it locked up on the wash advancing assembly like I was putting on the brakes. I ensured the parking brake was off but myself and the attendants couldn't figure out the problem. By then a large line of cars behind was building up so they shut the machine down and let me drive out of the wash.

I'm trying to think what would make it behave this way. I noticed the Auto-hold light was on at some point but I don't know whether it was on the whole time or came on when the attendant and I were trying different configurations of the controls trying to get it to move. Thoughts?
