I have a 2007 Yukon SLE that I really like, EXCEPT...I drive on some dirt roads and it is impossible to keep the dirt from packing onto the back window. Driving in snow also results in snow PACKING on the rear window. If you don't start the rear wiper early on, you can't keep the snow off the window. I feel it is a dangerous design and I am trading off my Yukon, despite how much I like the darn thing, for a vehicle with a different spoiler (for lack of a better word) above the rear window. That is what causes the problem. I had a 2003 Tahoe that didn't have this spoiler and the dirt and snow on the window was minimal. Talk to a car wash place, they'll tell you exactly what I am talking about
It's a great vehicle; has a lot of convenient things. Fuel mileage is as good as any SUV, even the smaller ones.
Boxiness of design makes it hard to see to park; do something about the blind spots when parking, etc., and the rear window really needs a design change.
