2021 2500HD Sierra Denali won't start but cranks over

[2021 2500hd denali]

I have a new 2021 2500HD Sierra Denali with 300+ miles on it , only owned it for about 5 weeks , its been on the tow truck 3 times because it won't start , it turns over however it won't start. I have gotten messages from on star saying "it's due for and oil change" , "service engine and transmission within 1 day" , "your battery is critically low" of which none of these messages makes any sense with the newness of this truck. I must add that my dealer has been very good with trying to help me out (to keep me smiling) however I'm not at all happy with GM at this point. this is pretty sad and concerning safety wise that a new vehicle such as this (or any for that matter) has this issue right out of the "box".

Ever figure this out?  I have the same issue.

2021 sierra 3700mi this JUST happened to me. of course i broke my foot and was at the dr when it stranded me, i did get it to start after about 10x over an hour period (dealer towtruck was 2-3hrs wait), luckly the dealer was close so I dropped it off. ill update tomorrow..this truck has been nothing but a huge disappointment since  i got it in november, im really hoping for good new but not holding my breath.

2021 gmc 3500 randomly will crank/ no start. Had it to the dealership 5 times. They just replace the starter which is not the problem but a bi- product of the  problem. Just got it back 2 weeks ago. . Still an issue. Heard so many theories. Does anyone know if the software uodate truly fixes
