Ok...drove 20+ miles to pickup the Grand kids:
AT4 4379 miles engine cranks but no start. Engine had been off for 20 minutes. Retried then it started.
Monday, May 24⋅08:45 AM.
It's never left me stranded but it is concerning.
I had my 2021 AT4 3.0L Diesel in for service to address the starting issue today. The service ticket said "Updated ECM software 11YN69061409 and tested" Time will tell.
Detail for the 3 failed to start problem:
