I have a 2023 GMC Sierra Denali diesel with the lz0 I do love the truck but it's been giving me a lot of issues lately sometimes on a long drive I will pull over just to get some fuel when I get done and started back up it will go into a limp mode and misfire really bad and all kinds of lights come on check engine light drive with caution reduce speed service emissions pretty much all of the lights come on the dash and sometimes when the truck sits overnight I will jump into it start it up I notice a three four second misfire with no check engine light on not sure what's going on I took it back to the dealer and they have done two repairs so far and the truck seems to be doing the same thing the lz0 Duramax diesel doesn't seem to be reliable I've had the truck for a year and I put 20,000 miles on it not supposed to be doing this at such low miles so I am probably going to do lemon law and hire a lawyer to see if I can get my money back.
