Engine had a misfire and would stall sometimes when you made a tight turn at low speeds. Found out it had a bad value seat causing it to have the misfire. Gm messed around and wouldn't fix it. Red other people had bad value seats too. Spent my own money to get it fixed.

2006 chevrolet colorado purchased new on 11/30/05. On may 27,2013 service engine soon(ses) came on and stayed on. Took truck to chevrolet dealership and diagnostic code revealed an engine misfire. They turned light off, test drove, light did not come back on and sent me on my way. June 17 2013 ses light came back on. Took back to dealership,they performed a "leak down test" that showed multiple misfires in engine, a $4000 repair. Contacted gm and was told they had sent a letter to colorado owners dated 8/2007 warning them this problem might occur and gm would extend the warranty to 7 years or 100,000 miles, whichever comes first to cover the problem. However, the letter also said not to take the truck for the fix if owner was not having the misfire problem. I never got such a letter-don't know why. I could not fix a problem I did not know I had! By the time my misfire problem occurred it was about 6 mths.out of the extended 7 year warranty but well under the 100,000 miles. Told all this to gm but they said "tuff". In my mind, by extending the warranty and even developing a special tool to help dealerships reduce labor costs, gm is acknowledging the defect in the factory built cylinder head. Gm says the only way to fix the misfire is to replace the cylinder head and it's integral parts, again a $4000 repair. Even a cursory search on the internet shows thousands of colorado owners with the same problem. This has to be a factory defect.

Like all the other reports and complaints I have read online about this type of vehicle. I have the same problem with my 2006 chevy colorado. I bought the truck 4 years ago almost brand new and I'm still paying for it but can't move it because it would not pass the state emissions test. I have spent about $1,000 trying to fix my truck, buying parts and replacing them because the check engine light came on. At the end I was told it had several misfires and had to do with the camshaft solenoid position. The truck would come to a complete stop while going to an intersection or a stop sign . I was told and also read that my only solution to fix this problem is to put in another engine but with time the same problem will come back. I guess this problem should be handled by the manufacturer and they're the ones who need to either fix them, give us our money back or something. Is not fair that we as consumers have to pay for something they did wrong. Now my truck is just standing there not able to drive it around and meanwhile I have to use someone else vehicle to move around or go to work.

Went to dealership in san angelo tx, did diagnostic for engine light being on dealership said problem was p0017 (cam actuator) did not have the money to fix it at the time dealership said it would be ok to drive it as is. Did research online and looked it up on book at auto parts store and p0017 says this "crankshaft position camshaft position correlation - bank 1 sensor b" what ever that means. But now I have major problems I still have that and a few more codes I have p0014 exhaust camshaft position timing over - advanced (bank 1), and p0300 random misfire detected.

2006 chevy colorado 4 cyl. 2.3l camshaft position actuator went bad at 68,000 miles causing rough idle, some stalling, and loss of power. Originally changed camshaft solenoid due to missing screen. Problem came back immediately, dealer tore apart engine and said the actual camshaft actuator needed replaced. Cost $1200. Truck was bought brand new, and serviced on schedule. Have been told this is a common problem for the colorados, and must be because there is even a technical service bulletin about it. Gm refuses to pay for it unless still under bumper to bumper warranty, which for my year expires at 36,000 miles or 3 years. At 67,000 miles, parts in the engine should not be tearing up. It is poor quality and dangerous to be driving.

Check engine light has come on due to several misfires. Got this checked out at the dealership and they said this was a common issue with this model vehicle and that I needed to replace the cylinder head as the manufacturer created a faulty seal for these engines and they tend to leak at idle. This fix was quoted at 3000 dollars. I checked around and found a bulletin released by chevrolet stating how they knew about the issue and basically saying how to fix it. Basically chevrolet owns up to this being their mistake but is unwilling to help out the vehicle owners. They want us to pay 3000 to fix a vehicle that is suffering from their mistake. Chevrolet should be willing to count their losses and help out owners with this issue.

A 2006 chevy colorado was having misfires prior to september 2010. This caused the check engine light to come on and so I took it to a chevy dealership for a diagnosis. The diagnosis is the same for thousands of chevy colorado engines as they need new seals, bolts, and a new head. My service manager said this has been a major issue with this engine since the introduction of this vehicle and it is due to a mechanical flaw and not wear and tear. These engines have put a major burden on general motors/chevrolet customers as they have to spend large amounts of money to correct a mechanical flaw noticed by many certified mechanics. Please take this information into consideration as I have done extensive research in finding that this is not an isolated problem and numerous customers have been failed by this such company.

Check engine light came on intermittently. Engine heated up and transmission would not shift into overdrive on freeway. Transmission shifts hard now and then. Checked website for any recalls on engine, took to dealership, still under warranty. They keep the truck for 2 weeks, did machine work on cylinder head, computer said all cylinders mis-firing. Print out from chevrolet said 'head replacement', which was not done. Notified gmc customer service and opened file. Back to dealership second time for drop in idle and misfire during driving. Could not find anything wrong. Dealership said to bring back if said condition gets worse.

Vehicle experiences engine miss fire code that causes check engine light to come on. Symptoms started at 45,000 miles. Dealer reset computer first time with no repairs needed. Computer showed multiple miss fires the second time. Dealer stated this is common with high mileage colorados due to carbon build up on valves. Dealer did check to ensure there was not a bad coil. Suggested using lucas fuel treatment. Did help rough idle and power. I was told next step will be to replace the head.

Truck misfiring on all cylinders since around june 2007. Check engine light on some, off some. June 19 dealer said misfiring on all cylinders and they were stumped. They first guessed bad gasoline then said computer needed reconfiguring. Still misfiring when I left shop. On july 19 returned to dealer. They said it was a gm problem that gm was aware of...possibly crankshaft sensor and for me to come back in two weeks. On aug 18 I took truck back to dealer after engine quit in a rolling turn in middle of intersection. Dealer replaced fuel pump and spark plugs and said they thought water was in fuel. Don't go back to same gas stations they said. I haven't. Truck still was misfiring when I left. On 9-26 I went back to dealer. Truck engine shut off while I was doing 70mph down busy interstate. Made it to side of road, restarted and continued on my way. Dealer said it was computer loosing communications internally and had clogged fuel injectors. Left dealer and truck still misfiring. Drove it for a day or two and when friend who went to lunch with me wondered if we were going to make it back from lunch I decided to call dealer. Called dealer and was told it was a software problem and that gm is working on it. Groan! Truck is almost out of warranty and I am wondering when next time engine will quit running and under what driving conditions. Thanks....roger dowdy

Engine loses power over 55mph and misfires on cylinder one. Engine light comes on. Dealer refuses to fix after looking at it and saying nothing has completely failed yet. They are waiting for me to be stranded on the side of the road I guess.
