My '04 Colorado Z71 crew cab has 376,000 as of yesterday and looks like it did when I got it except for the cracks in the windshield. The rear end wore out and had all the stuff inside it replaced at 360,000 for $1800.00. Engine does not use any oil I use Amsoil in the engine transmission and rear end. I am going to replace the tires soon this will be the 3rd set this set of tires has almost 160,000 miles on them. If you want to stop cupping on the inside of your front tires have them align the front tires straight up and down and keep air pressure about 40-42 pounds.
Besides the archaic styling, I really love the truck (113k miles). For those that complain about the power/interior space; buy a full size. Plenty of pep for a compact truck. I've hauled a lot of weight in this girl and she doesn't mind it much. I bought the CO because the Dakota had a hungry V8, the Ranger is tiny and the Taco and Frontier were about 2k more, plain and simple. It drives like a small SUV; smooth and easy on the blacktop. With a decent pair of shoes it takes the KS mud and CO snow with ease. The mpgs are great for most pre gas hike vehicles, not just trucks, about 18 city at 6500 ft. If you need a layman's truck for the occasional moving day or trash haul, the Colorado is it
I bought this truck used in 2005 and wondered why it was in a Used car lot at less than 1 year old. All kinds of electrical problems such as door locks/power windows not working but then start working after 2 weeks to a month. Dealer couldn't figure out problem and replaced under warranty BCM that didn't seem to fix problem. Transmission is hit and miss and often searches for gear to shift with pedal all the way to floor. Replaced 2 parking brakes at less than 50K. Have had two instances where brakes failed to stop and only a pulating sensation could be felt on dry road. 4WD HI setting doesn't work even after dealer tried to fix it. Stalling problems including hwy speeds. Hood comes loose.
I bought my '04 Colorado Crewcab Z71 4WD used with 20,000 miles. I think it's the best US build compact crewcab truck. Overall I like the truck. GM did a good job with the design and it's a good driving truck. So for I've had to replace a headlight assembly, front axle seal and CV shaft, and the auto dimming/compass rear view mirror. All were warranty repairs but it seems odd given the low mileage. I really wanted a Tacoma. I guess should expect a few problems since I saved approx. $6000-$7000.
Considering that my previous car was a 1996 Saturn SL with 202k miles, this was a definite step up. This is a nice size beginner truck that I got at a wonderful price. It handles and rides nicely. However, I have had numerous problems that required 1 minor engine rebuild and two half engine rebuilds. Yikes! Got another problem fixed today. GM threw an additional 75K Major Guard at me, so I am happy. My friend's 2K5 Nissan Frontier Crew is an overall nicer vehicle - it has the track system in the truck bed, better interior lighting, sunroof availability and more power. Mpg on Colorado is nice, though. I like my truck a lot, but if I "knew then what I know now", I wouldn't have bought it.
