In February 2015 my check engine light came on. After several repairs with my local mechanic he was unable to find the problem. I went to greenwood Chevrolet in hubbard, OH, and they reset my computer. However, before I got out of the auto lot, the check engine light reappeared. I returned to the service department and they then diagnosed a bad cylinder head and valves. The service manager reported this has been a problem with this particular engine and my online research revealed that Chevrolet recognized this problem and extended the warranty coverage to 7 years and 100,000 miles. My vehicle only had 87335 miles, but had been in service for 9 years, 7 months. I felt Chevrolet should have covered my repairs under the 100,000 miles extension even though I was over the 7 years. My reasoning is that Chevrolet was aware of this problem with this particular engine as evidenced by Chevrolet¿s service bulletin #07123a. I contacted the president and ceo of general motors and provided them with all my service records to offer proof of maintenance during my ownership. I heard nothing from them. I am filing this complaint because I felt gm should have covered the repairs because of the mileage of my vehicle and the care I had done to it. It cost me over $2000 to have this vehicle repaired.
There are several forum online each pretty much expressing the same problem. At the 100,000 mile mark the check engine light comes one indicating the #2 coil is bad. This doesn't seem to be the problem nor is it in the injectors. It seems with the online forums that are out there indicates there was a problem with the head on the 2005 Colorado but Chevrolet or gm is not investigating or talking about it.
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.
As my 2005 Colorado reached approximately 49,000 miles I noticed that it became more difficult to start and didn't run as smoothly as it had previously. A couple of weeks later, after the check engine light came on I had the truck serviced, and was told that the cylinder head and related components needed to be replaced at a cost of $3500 to $4000. Like many others, I have now learned that this was a common occurrence . And even worse, it seemed that it may be a recurring problem. I was told by the dealer that although gm has issued a technical service advisory and they were very aware of the problem Chevrolet will not issue a recall or take care of the problem when it occurred.
I have had problems with my truck and the check engine light, when serviced I found that it was the cylinder head that needed to be replaced. The service department at the chevy dealer said that it is a known and common occurrence in the 2005 5 cylinder Colorado. After doing research I found that many others had the same problem, some saying that ever 15000 miles they have had to replace the cylinder head, and one guy explained changing it for the 3rd time within the 2 years that he has owned his Colorado.
I was driving and my truck was shaking and spitting and sputtering and wasn't wanting to run right. When it was idling it was choppy the check engine light came on it was almost like the truck was possessed. I got to my friend's house and I checked to make sure that it was getting enough voltage from the battery like maybe the cables were loose but they weren't. I cranked the truck back up and it wasn't shaking and going crazy but when it ideals it doesn't sound right/isn't like it should be.
Check engine light came on in 90 day old vehicle - Chevrolet was fully aware of the problem when I took it to the dealer and fixed it. I had to pull over on the expressway to read my owners manual to determine if I could proceed - very dangerous. Chevrolet should be made to fix all Colorados before someone gets killed on the highway.
