2024 Chevy Duramax 2024 Problems Forum. 2 of mine run delo 5w40 year round and the newest one i'm trying the ultra low ash delo 600 adf 15w40. The 2024 trucks are plagued with problems, especially electrical.

Have always driven chevy from 1500 ltz, high country etc and 2500hd. Truck ran fine no issues, but around 600 miles i started.
