I have a 2023 Tahoe with a little over 800 miles on it. Two days ago I was turning onto my street and the vehicle went into neutral by itself. I told myself that I accidentally bumped the neutral button and didn't think anything else about it. Yesterday while at a stop light the headlights turned off and the dash said something along the lines of "Press start to restart vehicle" and wouldn't drive until I did. What could cause this to happen? Thank you for your help.
