In the past two weeks, I've had a two similar experiences as explain above. I was stopped at a traffic light and both times the truck shut off, including the radio. The StabilityTrak message appeared and, after I put the vehicle back in park, foot on the brake, I was able to restart it. The radio station came back on with a different station and format. Then it told me to open & close my driver side window. I have a 2019 GMC Sierra 1500 with 26K miles on it. The last work that I had done was an emergency repair of the engine oil coolant line [know problem in cold climates] 5K miles ago by the dealer. Of course they had to change the oil since the old stuff was on the ground. On my way back to the dealer next Tuesday to get the oil changed and to see if there were any codes to look at. I will have them check G218. I'm a little worried since the dealer told me over the phone that they never heard of this before. Just retired and didn't want to buy a new truck but this issue is concerning to me.
