Had issues with a noise from the front end. Didn't pay attention until it affected the shifting. Found out it's a transmission issue, $4400 issue btw. By the time I took it in I was 5000 miles past powertrain warranty. GMC's response? Have a nice day, you're screwed, don't expect us to help, have a nice day.
Expect to have a high cost repair while owning this vehicle. There is a reason other car manufacturers have better warranties, they are confident in their cars performance. GMC is confident in their cars having issues soon after the warranty expires.
Update: I recently sold this car as I was disappointed in the rising cost associated with repairs. Purchased a QX60 Infiniti to replace vehicle.
Bought in 2013. Love the seating configuration and space inside. Love inside and out. Thinking it might be time for a new one. The only major con I have is the seatbelts. We have a GMC truck and the seat belts are great. This one the latch hitch is extremely hard and bulky. Reminds me of an older model. The part that is secured to the seat will not move hardly at all. It is so stiff that it can cause major damage when accidently sitting on it or trying to crawl through the back. Several gashes on the knees. The head rest curls forward to much. Wish that was a little more adjustable but understand it may be for safety purposes. Overall a great choice!
