Have had crank no start 5 times since11/15/21, just turned over 10K miles. Had it happen twice in one day, took it in had the ECM re-flashed 1/17/22. Had crank no start again 2/5/22, returned to dealer, it's still there and they can't get it to fail. GM told them to replace ECM, now to see how long it takes to get that.
