I have seen numerous complaints for this same issue. My 2021 Acadia with 31,600 miles failed to start when parked in garage. It turned over just fine but wouldn't fire as if it wasn't getting any fuel. I had it towed to my regular mechanic.

Steering

No incident but steering assisted reduced could cause an issue. Also the fix is to reset the computer by detaching the negative pole on the battery. This could be an issue due to the heat in the car someone could get burned.
