Bought used from brother. 6.6L Diesel Duramax engine. Never a problem. Lots and lots of power with this engine. Maintenance easy for a DIY. I'll never go back to a gasoline powered P/U. I consistantly get 21 - 22 MPG on the highway, and 18 in town, when running with out a load. Everything solid, reliable and predictable. Would buy again in a minute. Brother chose this color. I'd never get navy blue. Requires lots of washing.
I bought this truck used with 72k miles. It has the 8.1/Allison combo. Right from the start the windshield washer,horn,interior lights did not work. I noticed many electrical glitches coming and going. Now the trans is giving me troubles not to mention the piston slap. Chevy refuses to take responsibilty for any of the issues. I understand the truck has 78k now and is 7 yrs old, but this many problems should not occur this early. Had Fords my whole life and never had this many problems. I tried Chevy and the problems never stop coming. They don't offer enough space to list all that has gone wrong. Chevy step up or you will lose customers!
My truck has the 6.0 L. engine, which for my money does everything it should. The truck has plenty of power and has been reliable. The few problems that I had were, a loose heat sheild on the exhaust, chrome came off the grill, and rear u-joints went at about 30,000 mi.. I feel I use the truck more than most of the yuppies who buy the big extended cab diesel. I plow snow with it and it also does all the work on my farm. I would buy this truck again in a heartbeat.
This is my first big truck of my own. I worked for a company and drove their trucks like this but they were poorly taken care of. I moved up from a S-10. This truck is great; lots of power, rides ok, very dependable, comfortable, quiet inside the cab -- not much road noise or wind noise.
Power wise I have been very happy with the truck, I pull a heavy gooseneck horse trailer cross country a couple times a year, as well as haul a lot of hay. Gas mileage stinks but, I expect that. It is very comfortable to drive also. The problem is the body design - the dang thing is literally coming to pieces. I live in a rural area with rough roads. This truck is just not designed to handle it. Soon I will have to have a flatbed put on because every brace on the wheel wells is broken loose and rattling. I have used G.M. trucks for 23 years, this one is the worst ever as far as durability. The next one will likely be a Dodge, or back to an older, tougher G.M.
