The seat recline adjustment handle broke off on both the passenger and driver's side. Apparently this happens to almost every seat. Very low grade metal used. After market replacement is available that is high quality. Rear sliding window lock broke off the glass. GM told me to go to apple auto glass to have it repaired. About two weeks ago the front passenger side wheel started squeaking. I believe its the pads rubbing against the caliper. Both tailgate cables broke and are difficult to fix/replace. I took it to a normal garage (because dealers are extremely expensive) and they said they can't do it. Lazy? Maybe, but it still looks difficult.
Other than that this truck runs great.
It has tonnes of power for a little truck, though it does lag between 2-3000rpm.
It is a little light in the rear-end for the power it has, and in wet weather I can always count on a fishtail or two. I must be careful when passing another vehicle in wet weather because when it drops to passing gear, the rear will swing out.
Overall I am very happy with this truck. I haven't had a problem with the power train or anything expensive and it performs really nicely.
I do recommend winters if driving in snow, they make a Huge difference.
The fuel economy is good for a truck, but not so good for a car (which it is obviously not). The books say about 12.5L/100km, but I get 450-500km per 60L tank (and I do drive over the speed limit).
As for the frowning face, I didn't mean to give that rating. I am very happy with this truck.
