...this time I happened to be next door from the dealer and the no start happened again (crank, rough, no start) over and over, repeatedly tried for about 5 min. and then was able to start and went directly next door to the dealer who checked codes and there was a code and then the engine light came on, also got an email from OnStar that there was a problem with the vehicle (don't remember giving them permission to spy on me or my vehicle but that's a separate issue). The dealer could not get me in that day so we scheduled a few days out and brought it back, luckily it was starting during this delay. As far as I know they reprogrammed according to some bulletin and it was starting ok for a while but then...

I don't remember exactly what the date was for this but it was earlier 2021 and the vehicle was purchased new in Oct. 2020 but definitely at less than 10K miles. Went to HomeDepot, when I came out it would not start, it was acting like it wanted to turn over but also seemed like the timing or something was screwy and was really rough and then would shut down quickly and not start. I attempted to start a few times and then waited about 5 min. and tried again and it started. Since I had recently filled up with gas, I attributed this occurrence to possibly bad gas but then it happened again later in the spring of 2020 so see that complaint...
