Silverado 1500 Duramax

[Italo]

Guys, 

since I purchased my 2021 Silverado 1500 Duramax sometimes when I want to start the engine, it crank but it won’t start and I have to wait that it times out. Then finally when I push the starter, the engine start right the way. 
Any other has a Duramax with the same issues? 
I appreciate your answers.

Thanks.

Step one is get the programming update done.

It was released for the LM2 in Nov 2021.

 

For most it corrects the 'crank/no-start' issue one LM2. 

 

Some trucks never did it even without the update. 

A few have reported still having the issue after the update.
