Like a rock it is NOT. The spare tire fell out on the freeway. It just dropped out from under the truck. The Speedometer and instrument cluster stopped functioning at 60,000 miles. The tailgate fell off. This truck is a piece of Crap. Chevy should be ashamed for putting it on the road.
You may have had some issues, but somehow, you still have kept your truck for 8 years and 200 000 miles (over 300 000 km!). If you haven't had any other major problems, then is that really that bad?
You complain about getting 200,000 miles out of the truck?
I would agree with disappointment of having problems with the instrument panel at 60,000 miles.
At what point did the other problems occur? Did you check with the dealer for service bulletins and recalls? There was an issue with the tailgates that they would fix.
Never heard of the spare tire issue though. Did someone not tighten it after changing or tire rotation? Dealership or a mechanic should have noticed it during regular maintenance check.
