Yes.
Sometimes if I open the vehicle to for a couple of minutes then close the door and lock with the fob, the display stays live for several minutes.
Mainly, when I've stopped the engine, gearbox in P, I open the door and a sign appears on the screen asking me to "Confirm" shut down. I tap confirm and sometimes the screen goes dark immediately, other times it takes a couple of minutes.
I think I've mentioned elsewhere, that I suspect that the basic chipsets were under specified for the task.
Unless there's been a change, increasing ADAS capabilities and other add-ons for the US market will load the system further...
