Colorado 5-cyl

Engine idle speed. When decelerating to stop, the engine idles so low that it quits and has to be restarted.

The contact owns a 2005 Chevrolet Colorado. The contact stated the vehicle was leaking oil. The vehicle was taken to the dealer who replaced a valve cover rocker and gasket hose. The dealer confirmed that there was excessive oil consumption in the engine. The manufacturer was contacted, but the vehicle was not repaired. The failure mileage was 45,000 and the current mileage was 60,000.

My sister has a 2005 Chevy Colorado she bought new. The cam sensor keeps going out on it. My brother-in-law is recovering from stage 4 cancer and this is their only vehicle and it needs to be fixed and at no cost to them. The part is poorly designed in regards to the condensation that builds up. Some people don't have garages or car ports and if the sensor gets wet it burns out. I will never buy a Chevy product, they don't stand behind their vehicles.

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.

Heater fan quit working on 1 2 and 3. but sometimes would come back on, when on 1 2 or 3. and when it was on you could smell plastic burning. And when checked the into it found the plug on the wiring harness that plugged into the resister on the fan was loose and causing the wires to melt. This loose plug was loose from the factory, no way could have got too small over the years. New plug and new resister placed concern if fire results could cause death injuries, garage fire or house fire if vehicle placed in garage at night.

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.

About 1 yr. And 1 month after I bought a Chevy Colorado, the thing shut off on me. The first time it left me on the side of I-55 and did not want to start. It did though, but the engine light was on, it soon went off. The dealer reprogrammed the computer. It has shut off on me 4 more times. The dealer will not fix the truck B/C it is not storing "codes". also, the traction control on the truck seems to engadge itself at the oddest of times when there is really no tire slippage and this has me sputtering and jumping while I'm trying to drive in traffic. At first start up, the truck has always made this rattling ping noise out of the muffler. Every time I step out of the truck, I shocks me, I beleive due to the nylon in the fabric seats. The turn signal will only "tick tock" when it wants to. The hood on the truck will "bow" or "bubble" in and out while driving, usually on the inerstate when there is some little wind blowing outside. The alarm on the truck has gone crazy on me a few times. I can unlock the door, it will go off but the radio inside the truck will be playing. If I were to cranck the truck up, turn the engine off, get out, and lock the door, the alarm will be going off about five minutes later. This cycle will keep going on until I reset the computer by pushing the gas pedal three times. All the dealer and GM wants to offer me is an extended warrenty, which the warrenty I have now is doing me absolutely no justice, I refused it. They told me that they cannot work on the truck B/C they cannot duplicate the problems at which they drove it twice, and the computer is not storing codes. This problem seems to be compleately spurratic and unpredictable. I have invested alot of money into this truck and still owe on it. I refuse to be forced to pay for and drive a hazzard.

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.
