The alternator went bad at around 40,000 miles.
The windshield wipers only function when it's dry out, unless I pull over and jiggle the wires, that started around 35,000 miles.
Fuel injectors went out around 48,000 miles.
Oxygen sensor went out around 30,000 miles, 42,000 miles, and 50,000 miles.
This truck is the worst 2 wheel drive vehicle I have ever driven in the rain or snow, even with weight in the back and studded tires all around.
The alternator and wiper problems I've had seem to run rampant on this model year and several years before and after this one. Chevrolet's customer service also leaves much to be desired.
One nice thing I can say about this truck is that the interior is wonderful. Everything is within easy reach, and the layout seems well thought out. Everything looks like it's nearly new on the interior, even after 10 years. I've had adults in the back seat and while it's a bit of a pinch to get them back there, there is ample room. However, comfort doesn't mean much when it's sitting in the shop all of the time.
