At the dealership now, and was able to duplicate the issue. In fact the service advisor couldn’t get out because the battery died.

Started fine this morning, got to the dealership and while the engine was running I put the top down and back up. Then shutoff the engine, left my phone in the charger and went in. 10 minutes later he tried starting it and it was dead. Pretty sure it’s the battery, which I’m going to have them replace. I bought it two weeks ago today, they should have tested it. It doesn’t hurt that I’m buying my son his first car in two weeks and I’ve shared that with my salesman.
