Has anyone been successful getting the problems fixed? I have had the screen going black and volume ramping up since oct 2019, 72 km.The truck has been in several times for updates and a new radio,still same old problems.The worst truck i ever had. I HAVE BEEN DRIVING GM PICKUPS SINCE 1978, ALL PURCHASED AT THE SAME DEALER. NO MORE !!! Unfortunatly no lemon law in ontario canada.
