2024 Chevy Duramax 2024 Problems. Not sure what the root cause of these. General motors has initiated a service update for the 2024 gmc sierra hd, addressing an issue with the 6.6l v8 l5p turbodiesel duramax engine.

I was planning on upgrading to a 2024 at4 duramax. The engine output of the duramax diesel has grown like barry bonds’s weight during his playing days.
