I believe it had to do with remote start as it was the first time I used it. I got in, put my foot on the brake, and pushed the start button. I don't know if it was immediately or later as none of the functions were being used as far as I remember. I picked up my daughter, then on the way home on the interstate is when I went to set the cruise, it gave me an ACC and Cruise error. I tried to turn off the cruise, turn off ACC, and whatever else while driving with no results improving. Eventually, I was off the interstate and able to pull over and shut it off and restart it (aircraft mech here, so it's the usual fix). Everything has worked fine since then.

Yesterday, I went to the store, and the vehicle didn't recognize the key and would not start. I had to toggle the door locks close/open, and then it worked. Not sure if it's related or not.
