Guess I am joining the list too. 2021 Silverado RST with 1059 miles. Yesterday, truck would not start with remote or when I got inside the cab. It would crank, but not turn over. I waited about an hour and the truck started (with engine light remaining on). I took right to dealership, and was told that low fuel rail pressure was the code thrown. Turns out to be the ECM. A bulletin has been released. They have to order the part and said it could take up to two weeks.
The dealership did flash the ECU and now the engine light is off and truck starts/runs normally. Hope nobody else runs into this problem.
