So I got this 2018 stinger gt2 and it started to flash battery discharge warning like the vehicle wasn’t running, the backup camera doesn’t show up, the climate controls don’t pop up, and I can’t go into my custom vehicle settings it just tells me vehicle must be running. I’ve taken it to dealers and they just say random bs and give up. Any help would be greatly appreciated as it’s very frustrating. I also have no CarPlay only bt works
