2026 Denali in the mountains.
What is everyone’s experience with using their Acadia in the mountains? We just bought a 2026 Denali Ultimate and I was disappointed to see that only a AT4 gets Hill Descent Control.
I’ve always just manually shifted on long descents but ran into major issues with our Kia Telluride. It couldn’t hold a gear and I nearly burned up the brakes. I am hoping GMC has a better transmission than the Kia.
