2019 Duramax Regen
If you have a L5P Duramax Don’t let them do the update for regens, mine used to to 4 to 6 hundred miles between regens, after the recall now 2 to 3 hundard miles

Are you sure? Qualified diesel mechanic? - Does the GM let you know when it is doing a regen? Or do you guess based on fuel economy?
- I hardly notice the regens, our 2019 is very happy....
- Better check if warranty is voided without update!
