C7 Screens Stay On After Shutting Down and Locking Car
Hey guys,
I’m facing a weird issue with my C7 Corvette. When I shut down the engine, get out, and lock the vehicle, the infotainment screen and instrument cluster refuse to turn off.
As you can see in the attached video, the screens just stay fully live. I haven't tried any troubleshooting or disconnected the battery yet, as I wanted to get your expert advice first.
Is this a known issue? What is the best way to start diagnosing this?
Thanks for any help!

How old is your battery? These cars get electrical issues when the battery is not top shape.

May still want to get the battery tested at a local auto parts store. Other than that, may have to make an appointment with a good repair shop and see what is going on.

It is the door latch assembly. Your window isn't indexing correctly either. I troubleshot the issue for a while before figuring mine out. It's not too hard to replace on a coupe, but it is a little more involved for a convertible.

Battery is size Group 48 US / H6 DIN. The OEM battery is only 660 CCA - but you can easily buy this battery size with at least 750 CCA. An AGM battery may last longer in a hot climate. I installed a Duracell Group 48 AGM w/ 760 CCA 3 years ago and have had zero issues.

However, it should turn off immediately once you open one of the doors and lock the vehicle.
