We have a brand new 2019 GMC Sierra..currently 4 months old, less than 4,000 miles. We got a black screen and can’t even turn the radio down. We tried turning the car off and on & no change. We turned it off and tried reading the owners manual & cranked back up after about 5 min. The screen came back on. Pretty bad this is already happening on a brand new truck...hope it’s not foresight into what’s to come...
