Not many vehicles can carry nine people or tow more than 8,000 pounds, but the GMC Denali is just such a vehicle. Beyond these particular talents, though, the Yukon has some shortcomings that might be too much for some buyers. The cabin is impressively quiet, and the front seats provide all-day comfort. The base suspension manages sharp impacts well, but surprisingly small road imperfections tend to give the cockpit the shakes. The powerful air conditioning has no issue regulating cabin temperatures.
