In summary, the car will start and stay started until the start button is released. If the button is held long enough, the car will stay on. This happens maybe 1 out of 10 times. And seems to happen on the coldest of days ( 10-15 F in the garage! ).

It seems this is supposedly operator error. I'd like to think that after using the remote start on three different GM vehicles (all work the same) and doing so probably 200++ times, that I know how to operate it correctly. I have made mistakes before, so I won't rule it out here. But I'd like to know what I'm doing wrong with this one vehicle that I don't do with my other cars.

ya mine does it every so often on my Malibu as well, seems like on very cold days, but cold here is -30 to -45, it will turn over and just idle dead...I just hit the unlock and lock again and it goes fine......
