Went to try and  remote start and it wouldn't. Hooked in a scanner and got the codes above. Any idea why it would be Cylinders 1,4,6,7? 2024 High Country 3500HD only 3000 miles.

 

Thanks in advance,

I have the same codes after I installed my two batteries says it could be a blown fuse or just needs a software update for the computer. Not sure what to do. Anyone have an idea? I called the dealer and ask them. They said that I would need to bring it back in $250 diagnostic fee. I feel like it’s just a simple issue.
