We had to send an email to mary.barra@gm.com (The GM CEO). I sent the email at 4 PM and received a phone call the next morning at 8 AM from GMs "Executive Resolution Seal". It's sad that's what one has to do to get attention, but it works. Everyone is spending a lot of money on these vehicles for a simple feature like this to work correctly. I told them that it was pointless to keep contacting the dealership because the issue is beyond something they can fix
This is what we sent -
CarPlay seems to have many issues with the new infotainment system by Google. Call waiting does not work. When on a phone call and a new call comes in, the car automatically connects to the new call while cutting off the previous call. The only solution to continue either conversation is to hang up both calls and call each person back individually hoping not to get "interrupted" by another call. This feature is supposed to make phone conversations EASIER not more DANGEROUS. We have had CarPlay in a 2017 Escalade, a 2019 Sierra 2500 and a 2021 Sierra 2500 with NO ISSUES! Additionally, when connected to CarPlay, the screen sometimes glitches and becomes pixelated. Again, this does not happen on our 2021 Sierra or other past vehicles
