I bought my truck with 6 miles on the odometer in March 2004. It was recalled for the instrument panel. Very good experience there. While it was under warrenty, I had it in for new Cats and O2 sensors, three times, but never again since. The last warrenty items I had replaced were the comfort control switches. I now have 190,000 miles on the truck and, get this....I'm replacing the brake pads for the first time, and the rotors have very little wear. This is by far the best vehicle I've ever owned.
My truck is a daily driver in the city but also a back road wonder on the weekends. In the winter I use four wheel drive for duck hunting with my sons in the country. It has been from Texas to California and many Colorado trips. It look good in the field, but when it is cleaned up it looks good under the city lights. Safe, dependable and a real pleasure. Maybe the best vehicle I have ever owned, out of maybe 11-12 cars and trucks.
I purchased used with 40,000 miles for the 4x4. I live in a semi-rural area and the roads don't get treated. I have the 5.3 V8, and G80 locker. For the two months I've driven, it has worked like a charm. Been using the AutoTrac 4x4 which is the button system that goes into 4WD Auto, which is AWD. Had to dig the wheels out a little when I drove into 3' high snow in my driveway. I rocked the truck back and forth a couple of times and was out. I get around 20 mpg on country roads and highway. I don't drive heavy footed, usually 65-75 hwy. Only thing that I find annoying is the wipers can't be lifted off the windshield when it snows, because of the hood design. Takes longer to clean the window.
I purchased new in late 03. Has been a very good truck for me. About 1000 miles a year I would tow loads that are 75% of max according to the tech manual. No issues on engine or trans for 50k miles. In fact, it towed like a dream. At 53k miles I lost my transmission. No excessive driving or cliff jumping. It broke without warning coming out of a church parking lot and costs me $3k to replace the entire transmission. IMHO there’s no excuse for a transmission to break at 53k miles. Truck is out of warranty so the cost is on me. Chevy dealership says, “so sorry. What a rare oddity to lose a trans at 53k miles”. I’ll remember that at trade-in time.
