We currently have 4200 miles and haven't had any problems except for a random "service" msg or two. Overall we are still happy with our Trailblazer and have no regrets at all. One thing I really want to upgrade is the wheels. Not a fan of the RS wheels and not really sure why, lol. I actually like the look of the LT wheels the best, followed by the Activ wheels, but we'll probably go aftermarket when the time comes.
