I am having a problem with my 2016 Silverado's screen blacking out several times over the past 3 weeks. It seems mostly related to having my phone plugged into the charger or even changing to a different podcast or song. It's getting frustrating. I saw a YouTube video where a guy had a similar issue and just removed and replaced the spark plug (not a new one, same one) and he said it fixed it. I've tried different charging cords but the longer this goes on, the less related it seems to charging my phone. Any tips?
