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

Travelling I-270 in dublin, ohio around 2pm at approximately 70mph when truck engine died. The emergency flashers and radio were still operational. Pulled to right side of highway and attempted to stop. The brakes were losing power, but there was enough to slow and then stop. Dash indicated 'reduced power'. Upon pulling off road, wife contacted aaa, while I looked under hood for anything obvious such as battery terminals loose or any plugs being unplugged. Nothing appeared out of order, I got back into truck and it started. I told wife to tell aaa we would attempt to make it home, approximately 2 hours away. Through this all, the truck had stopped running 6 more times before we got home. It restarted after sitting a few minutes each time.truck was towed to local chevy dealership. After a few days, received call truck was repaired. The PCM (power control module) was replaced. When I got into vehicle there was a sheet of paper on transmission hump explaining what a refurbished part is (the federal safety agency doc#2). I glanced at it and thought it was mistake since I was charged $500 for the part alone. Total cost was $772.36 (the federal safety agency doc#1). When I got home I reviewed the paperwork, saw they had installed a used part and immediately called. They said a new part was not available. I contacted general motors (the federal safety agency doc#4 & the federal safety agency doc#5) and they were no help. I also contacted AC delco and they confirmed the part was not available as new. I thought manufacturers were required to make parts available for vehicles 10 years after production stopped. The truck is 10 years old, but production of that generation stopped in 2012.

2005 chevrolet colorado 102,000 miles. Vehicle flashes "reduced power" on information display then shuts down engine. Luckily I was able to coast in to a parking lot out of traffic. Engine refuses to start for a couple of minutes then fires up. Has done this a number of times since. Engine code given is p0601 "check sum error", ie computer glitch. This is an unsafe condition, instead of reducing the engine so that one might get out of thraffic, the fact that it kills the engine is a major safeyt risk. Poor programming to say the least.

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).

While driving, the radio will lose power, then the A/C will stop working, then the entire dash will lose power (no speed, tac or gas gauges). Then all warning/ failure lights come on. Will reset after you turn car off. Been to dealer 7 times for same problem.
