I purchasing a 2006 GMC Envoy XL Denali on 12/1/14. On 12/3, my truck began acting very strange when I would turn corners. I noticed the switch showed the truck in 2x4 however the light indicated it was in 4x4. The truck would not switch out of 4 wheel drive. On 12/5, when I backed out of my drive way I noticed something had been leaking for my truck. After investigating found it was leaking anti-freeze. I took it to a shop and found that the encoder motor for the transfer switch was bad and there was a broken water valve under the anti-freeze reservoir. While I realize things will happen and parts will stop working, I feel it a great disservice that after having spending all this money to purchase the vehicle and only having it for 1 week, that I then have to put out another $700.00 to have it fixed. In April, I had to have the entire steering column replaced, costing another 850.00. And now the shocks are going bad. Won't buy from here ever again!!!
