How bout this , 1,500 miles on a 2019 Sierra 2 Dr w/t
98% of the time the radio comes on at start up even though it was turned off
"Distracted" warning rarely appears
One time I turned the headlights to the on position from the auto
position and regained control of the infotainment center.
Radio loud spurts, 100% for a 1/4 of a second then back to where it
was. Multiple times
Screen and buttons do not respond and has even gone black. Multiple
times a week , not so much now.
Climate control blower--shut the truck off while the blower is running
@ any speed , re-start the truck later , blower comes full blast even
though the control was in the off position @ start up . Regain
control by selecting any speed .
