Have the GMC equivalent (Envoy). The one issue I've had is the tachometer stops working intermittently. I was hoping for a little better mileage (I'm getting about 18.5 mpg). Traded the Tahoe i liked down for a mileage gain, and didn't get as much as I was hoping for. The 3rd row seating in the XL is nice though. All in all though, I'm satisfied with the vehicle.
