Suspected 12v battery dead.. Currently at service center. Happened right after getting a new coilovers set installed... also have a stealth hitch....

I'll make sure to disconnect the line fuse for the stealth hitch when I get it back!

This is very similar to the stories about people who directly connected subwoofer amps or other audio amps into the 12-volt system without an isolating relay. Didn't go well for them either

It ended up not being the battery though. Still disconnected it

So what was the diagnosis?
