Hello all!
Just purchased a2020 XL Denali with 90k on it.
So far seems very good. Bit different to driving the F250, and definitely easier with the baby!

Would love any advice on owning these!

Thanks
HJAB

Welcome to the Forum from NH.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

Pics of the truck, please. If we can't see it, it does not exist.

You are already receiving sage advice from the knowledgeable folks on this Forum.

Change ALL fluids, so that you have a new baseline on them. Send a used oil sample to Blackstone Labs for analysis, and you'll learn a lot about the contition of your motor.

Get the AFM tuned out, at the very least.
