Random times, my 7" LCD goes black, sometimes still responsive to touch depending on where the buttons would be (not visible). Today though, the screen went completely off, no multimedia function at all.. tried restarting car 3 times and did not recover. Tried again hours later and then it's back on as if nothing happened. Taking car into service tomorrow. 2018, 1500 miles... 1 month old, Silver LX PHEV. Anyone else getting black screens randomly?
