2021 Honda Pilot drivetrain & axles problems

I just bought my brand new 2021 honda pilot I had it for 1 week so I decided to take it to las vegas on the way there it was fine but on the way home I'm coming down I started to feel a jerk in the transmission I didn't think nothing of it so I kept driving. But for a new car it should not be doing anything like that at all so I took it to honda dealer and they did a multi inspection check and said they didn't find anything wrong with it and everything shift fine but when I took it home a week later it's happening…

The contact owns a 2021 Honda Pilot. The contact stated that while stopped at a traffic signal, the vehicle independently shifted into neutral(N). The contact shifted vehicle into park(P) and turned off and restarted the vehicle and shifted into drive(D). There were no warning lights illuminated. The contact had the vehicle towed to a dealer. The dealer diagnosed the vehicle with a faulty brake switch and determined that the 12-Volt battery needed to be replaced.
