Colorado rough ride

I bought my new Colorado 2x4, LS, regular cab, June, 2004 and it has a very rough and unstable ride on any type of road surface. This roadability is particularly troublesome when out on the open highway. I've had three pickups prior to this one, the last being a '97 S-10, and none of them rode this poorly. I've had the tire pressure checked, and have had it into the dealer once for the problem. It's such a problem that I've aleady notified Chevy, and may consider selling it off even though it's got less than 500 miles on the odometer! Anyone out there have similar problems or solutions????

Is it genuinely unstable or just stiffer than you're use to? Do you have the regular Colorado (Z85), Offroad (Z71), or Sport (ZQ8) suspension package? I have an extended cab sport model and I can see how it might be stiff for someone not use to the "sporty" feel. I'd say mine is more "sensitive" than unstable though.

If you're in a regular model though and it feels wrong, definitely have it checked. As far as it being a mechanical problem, I'd say check the torque/tightness of the shocks and stabilizer bar. No matter what, warranty should cover it at least.

I have the same type of vehicle as you and mine does the same exact thing, there are other people having the same problem on this site in another discussion thread. I also reported it to Chevy this has to be a design problem with the regular cab, the dealers don't know what to do and Chevy doesn't know what to tell them. Other than this problem I like the truck but I'm not going to put up with the rough ride, I may have to trade it in on a Ranger or Toyota.

:lol2: I have been battling with GM for 6 months so far with a similar porblem. The truck is a 4 cylinder extend cab and it rides as rough as a garbage truck. I have never dealt with as miserable people as GM. They simple have given up trying to fix the truck and have told me to live with it. Oh yea and an offer of free oil changes.

just go ahead and trade it as soon as you can without losing your butt on it. I've had mine since may 2004 and still owe around $17k. Trade value at nissan, toyota, and infiniti as of march 5, 2005 is $10500 at most. It's a 2004 extended cab sport model with every option that was available in May 2004. Thanks a lot GM for such worthless vehicles that we're forced to keep them even when they're in the shop at least once a month to have parts replaced! I loved the truck at first. But now at 14000 miles, the ride has gotten rougher over time instead of smoother, entire computer has been replaced, 90% of the steering sys. has been replaced, front repainted, and then there are the minor flaws that I fixed for myself like rattles and squeeks all over the place. And lets mention that an inner fender well fell out while crossing railroad tracks and another is loose. Most likely, those plastic pins can't handle vibrations of driving on rough city streets. I'll never own GM again. No saab, opel, subaru, daewoo, chevy, gmc, saturn.... Nothing gm ever again. Only pure japanese or pure german (no chrystler-benz either) from now on. Take my lead people. Your bank accounts will thank you in the end.

I can see being upset about losing parts going over railroad tracks. The truck is new, it will take a few years to work all the bugs out... that's the first computer I know of going out. Somethign some people don't seem to know is trucks have a rough ride. They're made to have weight in them. Put 500 pounds in the back, and it will ride better. Or... you could buy a car if you want a nice smooth ride. Am I the only one who is sick of business people driving trucks from the suburbs into the city and back every day?

If your trucks are actually defective or if they've seen AT LEAST gravel, unboxed cargo, or a trailer, please ignore what I said.

I know what you mean about city people complaining and wanting a car-like ride. I, however, traded an 89 silverado for the colorado. Had a 79 silverado before that. So I wasn't expecting a clean ride but I was expecting reliability. Those older trucks were possibly more reliable than my colorado though. My opinion as an engineer is that a worthwhile quality assurance program should have caught more of the issues that consumers (other than just me) have found in the 04 colorado. Balancer shaft vibration, idle speed calibration, a/c compressor noises, water leaks, etc. all should have been caught and fixed before the product shipped.

Well, if you are referring to the horrendous vibration issue that a lot of these Colorados have... I feel for you.

We lemon-lawed ours, and got a Silverado instead.

Our vibration was so bad it bounced you in the seat. GM didnt want to hear from us until we sent the Lemon Law letter, then they were bending over backwards to help.
