I purchase my used Rainier in December of 2007. For the most part I am very satisfied. I have had ongoing stabiltrack issues, and the driver's window keeps coming out of the track. My most recent problem was that the shift sensor, wiring harness and valve body went out at 40,600 miles. I am thankful for the 50,000 mile warranty. I was told that there is nothing that can be done about the window. "Don't roll it down while going down the road". GM and the dealership refused to do a transmission service after my transmission got hot. They had it pulled apart and had the filter in their hand. I love the vehicle, but can't say that I will buy GM because of the service.
Comfort and design. Does very well on ice and snow.
Complete the leather on the two front seats. The front cup design is not very convenient. Take care of the customers and fix any warranty issues or repairs.
