Excellent Quality SUV
By Joseph U on 1/16/2026 12:03:02 AM
My experience with the 2018 GMC Yukon Denali Sport, 6.2, is that it is an amazing machine! Zero Recalls! The powerful 6.2 gas engine is incredible. 5 stars all the way! - 5.0
Great truck
By Bob R on 11/20/2025 4:41:53 PM
With the 6.3 engine it has more power than I will ever need great modern leather! It has 120,0000 mile runs like a top we change the oil regularly and it rides as good as our Cadillac did! It probably needs shocks about now but this has been a great truck! - 5.0
