I bought my 2004 Yukon 4x4 new, and I am content on keeping it. It delivers lots of power and is a very safe SUV to drive in all kinds of conditions. It will pull about anything you can hook up to it, yet will result in good fuel economy for something this big. In the past when I had to get a group of kids somewhere not far away, I had sometimes 18-20 kids in it (took to the side roads of course). Besides having a couple of small items go wrong, it has been pretty much a perfect vehicle. If you are looking for a load 'er up and go set of wheels, you won't go wrong with a Yukon!
It is the greatest truck I have had. I had a 1995 Chevy Tahoe, I would never buy another one, although the gas is not the greatest, the interior is great and the truck is quick considering it weighs just over 5,000 lbs. All in All I love my 2004 Denali, and would never trade it for anything, except maybe a new Denali.
I bought my 04 Yukon brand new in 10/04 and so far it has been the best SUV we have owned. The third row seat access could be better (2nd row seat should fold all the way down rather than stepping on the back of it). It drives great in the snow and ice, so far I have only used the 4WD once this Winter (Jan 06). This SUV is a beast, I only wish it wouldn't burn so much gas and what ever happened to .99 cents per gal, $60 for a full tank and only 310 miles OUCH! I don't drive it too much, time for engine improvement. Overall is great vehile and very dependable and roomy. Kids and mom love it.
The spare tire is a 16" tire. At 25,300 mile I had tire damage, drove 200 miles on spare with 17" regular tires. Had to repace all 4 tires due to being a AWD and 25M miles on 35M mile tires. Repaced spare with correct size. Contacted GM and received a reply of nothing. Out $875.00 for tires at 25M miles. How cheap will GM go on a $50,000 car? Please check this problem if you buy a GM AWD. They will not stand behind any mechanical problem that may occur. They could at least put the correct spare tire on these expensive cars.
