This is a nice looking SUV, but that is one of the only good things i can say. Bought mine brand new, and have numerous ongoing problems. Excessive oil consumption, throttle body problems, and battery issues. The dealers and GM don't know how to fix many of the issues. GM customer support is useless unless the truck is still under warranty. They won't even help the dealer solve the problem. This is not the SUV to buy for reliability or long term.
Very comfortable vehicle but many, many problems with all the little sensors plus the 5.3 liter motor has a major defect and burns oil. GM says 1 quart per 2,000 miles is okay but after 80,000 miles it burns double that. It will even fail inspection for a lean cylinder due to the oil consumption. The services stabilitrack / traction control will also pop on for you on multiple occasions. The tires monitoring system always needs to be reset, the cruise control works only when it wants too and the vehicle used allot of fuel. They say 13c/19hwy but on average you get 14.9 total.
Purchased this car on 01/02/07 to replace our 2001 Suburban LT 4x4. Demo with 1000 miles on it. Immediately drove from SF Bay area to Lake Tahoe for a week's vacation. Remote start was unbelievable. Start the car from the house, 10 minutes later, the car is warmed up, heat on full, heated seats on, etc. Such a pleasure! Kids love the DVD with wireless headsets, mom can listen to her music, too! Handles the mountain altitude extremely well - the 6-speed automatic really shifts smoothly on the steep inclines. Much better than the 'Burb. Poor FM reception and distance. Great XM radio, but we need road conditions, etc.
I love my Yukon. However, it has been burning oil for about 3 years now. Three years ago I took it to my original dealership who told me that it was normal (with a straight face!). They refused to do anything. Fast forward to 96000 miles, took it to a Chevy dealership who listened to me and said they have had this problem. Next Monday it's going in to have the "shields" put in. I am still worried. GM customer service told me they didn't know anything about any problems, that the dealership handles all of this. I know they know, but as long as they can deny it, they will. Will post again when it is allegedly fixed. Very very unhappy with GM's response.
I had two Expeditions before getting the Denali XL. The first Expedition (pre 2003 model) was great. The next Expedition was awful! Which makes the Denali look that much better! I love the space (Expedition lacked terribly), love the look, love the package (I got it loaded out), love everything about it (except of course the MPG... but was expected!). If you are looking for a wonderful SUV that is large enough to take a family of 5 (3 boys and mom and dad) on vacation yet nimble enough to park in the Walmart parking lot, this is it! Can't give it enough praise!
