I bought my Yukon a little over 2 years ago and used to love it until recently, I have had to replace the rear end, 2 waterpumps, and the air conditioning. I thought I was all done but now my catalytic converter has gone out and I am sure that is not all that is going to go wrong. My back window is slowly quiting when you roll it up and my emergency brake has quit working all together. This is by far the worst car I have ever had, and the most expensive. I will not buy another one just for these reasons. Other than that, it is a great car, when it is running! I find that is great for the whole family and even pets and groceries but the reliabity just isn't there.
If you've got children, or adults for that matter, to haul around, your going to love this vehicle! Have cargo and humans/pets? This vehicle CANNOT be beat. I'm on my second one, and haven't had a moments trouble with either. With the model change, (2002?), the turn radius improved immensely; making parking somewhat easier. Seats are comfortable, power is wonderful.
I have owned my Yukon for 3 years and 30,000 miles. I love the power, handling and comfort this vehicle offers. I have had to do only regular maintenance which usually includes the front hubs at around 100,000 miles. This thing fits 4 foot by 8 ft sheets of plywood inside and is still is capable of 19 mpg on the highway!I average 16 overall with mostly rural driving in the mountains. This vehicle is just as well built and reliable as my Honda Accord!
Bought it new in July 2002. Excellent vehicle, particularly if you do a lot of camping or fishing. GREAT gear space when all seats are in use. Only 1 early problem, parking brake cable stuck under warranty, wearing out parking brake shoes. Only other problem - oxygen sensors went bad at 60,000 miles, too early, perhaps got splashed hard with salt brine or water. Good:The front disc pads lasted 70000 miles, rear disc pads 80000 miles, battery 5 years, changed it when I had the Dexcool coolant changed at 5yrs. Original tires lasted 70000 miles. No problems with A/C or transmission. Overall very reliable. 15mpg city, 14 mpg city when very cold. 20mpg highway at 55-60mph; 18mpg at 70. 17@75.
