Ok so ive been here enough to notice this in other members. For those who have remote start maybe 2-10 remote starts wont start. the procedure is to lock the doors then hold remote start. i double lock my doors till i hear the horn acknowledge and flashers blink. then i hold remote start for about 3 seconds then the flashers acknowledge and 1 second later it starts. Well i have multiple videos in a few months span that show me doing the procedure correctly and the flashers acknowledge the start command but it just doesn't do it. yesterday mine did it and we had a 14 CTD in for the same issues.
I have two RO from the dealer where i work stating they "Fixed it" and still happens. im going to have our service manager email my videos and statement showing he has verified this....
WE all need to document this so GM knows its an issue with software and send out a update software, because there current software fix aint doing it
