Hi there! I have been having this intermittent (every day ish) issue with my 2014 GMC Sierra Denali in which in the span of about 2 seconds this occurs while driving: Vehicle will pop itself out of gear, causing it to rev up in neutral and then go back into gear about a second later. Doors will unlock and lock back up. Sometimes the Infotainment screen will turn off and turn back on again 5 seconds later, sometimes it does not turn off at all. I would take it into the dealer but the dealer in my country is not very experienced and i feel they would not pinpoint the issue, as well as the fact that i do not have the time and do not want to end up paying a fortune for this. Thank you in advance for any assistance you can give me.
