(1) pulled the MS out of the garage into my driveway so that I could wash it. I got out to get my supplies and noticed the car was binging the chimes. Like when a door is open. Nothing I could do would stop it. I made sure all doors were fully closed, seat belts weren't connected, and made sure front and rear trunk were closed properly. I simply could not figure out what was causing the chime to sound. The dashboard and the MCU were black. When I got back in the car for the third time, the dash and MCU lit up as always but chime kept sounding. I finally said the hell with it and started washing the car. After about 10-15 minutes they went off by themselves. (2) Ever since I brought the car home when delivered whenever I got out of the car after parking it, the dash display, MCU, A/C and radio continued working when I shut the door when I was out. They would go black after a few seconds on their own or until I used the fob and locked the door. I could see into the car that the dash said "car off." Yesterday, I got out of the car and both the dash and the MCU went black immediately and it has since behaved like that every time I park and get out. Which is the correct behavior?
