    Unable to close driver door. Keep a wrench in your glove box for 12V disconnect!

    New issue for me today on my '23 GTPE. Today my driver door got stuck open. The mechanism that pushes it open was stuck in the open position (see photo). It would not retract no matter how hard it was pushed. I didn't even notice at first until I pushed the door closed and it bounced open back...

    I've had the car for 12 days. Yesterday, out of nowhere it starts giving me Transmission Not in Park error when I'm slowing down for a light or an intersection; a Door Fault Service Required error; and it also returned a Hill Start Assist Failure warning.

    Stranded, Stop Safely Now, 12volt battery dies

    So I'm pretty sure this has been talked about several times in the forum. Time for me to present my story. Before you ask, it is a First Edition, and yes it was built before Feb 3rd.
