I have a 2005 chevy colorado standard cab 2.8 liter after 3 years I noticed engine internal noise start it up now it sounds like a diesel a lot of stuff is knocking around inside the motor I heard it was some type of recall on that but I'm not sure I do remember I had problems with throttle body have been replaced twice after this replacement from a certified technician that's when the problem of reduced power failure emitting from my dash could not go over 40 miles an hour check engine light would come on so I was told to disconnect battery for about an hour to let computer reboot and the problem would go away just for a little while when the motor is cold there's no noise it sounds like it's new but when it heats up that's when all the noises begin I always change my oil out every 3000 miles or 3 months I used castles 70,000 mi plus because I have 110000 mi on the vehicle I don't know if anyone who's had the same problem as far as the knocking in the motor but I do know that people have had problems with their throttle bodies malfunctioning and causing the truck to run rough and slow and sluggish now I don't drive it very far because I'm afraid that power reduction light will come on in my dash therefore I can't go over 40 miles an hour which I've mentioned this before all I can say is after this with the throttle body motor has been giving me problems vehicle was in motion

Faulty cam actuator solenoid causes loss of power and rough idling. Common to 2005-2006 chevy colorado/gmc canyons. This fault also releases debris into the engine that causes potential for further damage. Occurred at 70k miles on my vehicle without prior warning and all regularly scheduled maintenance has been performed. Replacement of the solenoid and an oil change is necessary to correct the issue (that gm is aware of since they've redesigned the solenoid since this edition).

Colorado, 5-cylinder engine problems, stalling and rough idling. Stalls and runs poorly. Why has dealer not issued recall for all of these for cylinder head work? Dealer wants me to pay for it.

2005 chevrolet colorado 5 cylinder 4 wheel drive automatic 68,000 mi engine misfire 7 times taken to garage $1,300 paid and no one could fix problem. Finally took vehicle to dealer who charged $325 to change spark plugs and then admitted that there was a problem with this engine. Intake valve seals are defective. Now vehicle needs a $500 repair of front transaxle seal. All electrical connectors on this vehicle are of inferior quality, I have experienced 3 failures of stoplamp wiring,4 failures of signal light wiring, and 2 failures of A/C blower motor, all due to poor electrical connectors. My concern is that in case of an accident the air bags would not deploy because of a similar problem. This is a potential safety issue, and should be evaluated.

Dt: the vehicle was taken to two different chevrolet dealers. It had a rough idle. The consumer felt that it was due to defective tires. They were not willing to replace the tires. Consumer stated there were bubbles on the tires on the sidewall. Ameritech tr general tires. This started a month or two after purchase, but the tires were getting worse with more use. The chevrolet dealership stated that it was the suspension, but they were not fixing the problem although it was under warranty.
