We purchased this vehicle in December 2011. We love everything about it! Comfortable, spacious interior and the 6.0 litre engine performs fantastic. Of course the only draw back is the gas mileage but our intent was for a spacious vehicle in which we can haul people and kids around in. The blue/green crystal paint is beautiful and we get comments about it everywhere we go. The fit and finish throughout is quality.
The Yukon Denali is overall a great car. Our other car is a 2008 Town and Country Touring Edition. That van had been the kids' favorite until we got this car. Now, the kids don't want to ride in mommy's car anymore. It has plenty of seating (3 rows, seats 7 with the middle row of seats having bucket seats) and features galore, from heated, memory leather seats and sunroof to DVD player and plenty of power outlets. The performance is great, with LOTS of power and passing ability. Just be careful, because it's very easy to get going faster than you realize it this vehicle. Set the cruise control whenever possible. There are only two drawbacks to it that I have found. One is that there is virtually NO space behind the back seat, maybe a foot between the third row of seats and the liftgate. I usually keep the third row folded up to create more space for groceries, etc., unless someone is riding back there. That will have to stop soon, however, since we will be having our third child soon, and our oldest child will have to move to the back. The space problem would be better if we had the XL (extended length) version of the Yukon Denali, but that would make for a tight fit in our garage. I replaced a 2007 Chevy Trailblazer with this standard length Yukon Denali. It adds a third row of seats and is only 9 inches longer than the Trailblazer. It also adds 1700 pounds of towing capacity (8300 pounds vs. 6600 for the Trailblazer), which makes me very excited to hit the road with our travel trailer. The Denali XL is considerably longer, which would help with the tight space in the back, but it would make the other problem with the Denali even worse. My Denali gets only about 13.5 MPG so far, with mostly city driving, and that is using a very light foot on the gas. More "normal" acceleration gives about 12.5 MPG in the city. On the highway, I'm lucky to get 17 MPG. That is the tradeoff for getting a huge, heavy SUV with lots of power and capabilities. These numbers seem pretty consistent with other very large SUVs, so if that is what you are looking for, you'll have to live with high gas bills no matter what model you get. You can't have it all, right? The quality has been great so far. The fit and finish is good, with no noticeable gaps inside or out, and overall the materials in the interior are nice. I have had no problems or complaints with any mechanical systems, either. Overall, I would highly recommend this vehicle to anyone wanting a strong, comfortable, feature-loaded car, as long as you can deal with the poor mileage. If getting good gas mileage is at the top of your priority list, you should look elsewhere.
The Yukon is very comfortable. The options are nice. The advertised gas mileage of 12/17 is only a dream (more like 10/13.5). interior trim pieces are always falling off, but they snap right back into place. The air ride on the reaer driver side is noisey (techs say that is the norm?????). The navigation dvd has to removed and reinserted almost daily. The rear heat works when it wants too. The overall drive train/engine seems great.I am still undecided as to keeping the vehicle or not. My kids love it, and it is mostly petty things that I complian about.
