Which is the top of the range GMC Sierra Denali?
Right at the top of the Sierra 2500HD range sits the fully loaded Denali. Despite its price, it’s likely to once again be one of the more popular trims thanks to its standard 4WD, a premium Bose sound system, and by far the most driver aids fitted as standard.

No 30% or 1000 mile notification, just an Action Required Now-engine will shut down in 500 miles. The power seems to be OK. I have taken it to a shop on this trip, they checked the system for leaks and said they make some ECM updates–it didn’t change anything.
