New to GMC

[twescaba79]

Hello all you professional grade(rs)!

While I have not yet purchased my truck, I wanted to gauge the community on my upcoming purchase.

I am going to purchase a 2021 GMC Sierra Denali with about 94,000 miles. For a diesel, I know it is barely broken in. My brother in law is a GMC master tech and he has gone over the truck (for sale at the dealership). The truck has all the amenities my wife and I are looking for, we just want to know what to be on the lookout for for maintenance and any possible issues. Thanks for any feedback!

Welcome.

Post pics when you get it home.

Your bil would know better than us here. The CCV is one thing to look out for.

My '21 Denali with 43k miles has been trouble free.

Sounds like the previous owner kept it well maintained. The only major upcoming maintenance will be the recommended replacement interval for the belt that drives the oil pump in the LM2 at 150,000 miles. The belt is located at the back of the engine which will require the transmission to be dropped to access it.
