I have a fully loaded GMC AT-4 2021 and so many problems with electronic radar couple times didn’t crash 💥:( GPS don’t work :( SD Card not reading:( Cruise control sometimes not working temporarily disengaged :( Auto highbeams keep blinding people when there’s no car turns off when there’s a car turns on :( Cameras sometimes it’s gray sometimes is blue sometimes don’t work :( Parking sensors :( Auto CarPlay not reading 80% Charging ports not charging :( Screen sometimes shuts off sometimes it’s smaller sometimes freezers :( Anything it’s electronic piece of crap shame on GM :( GMC technology to pee on :( junk Just imagine to drive itself it’s gonna kill everybody :(
