| 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 selenoid 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. | |||

| Truck will go into reduced power mode while driving. when it does this it will chime a few times and then drop the speed you are driving at to whatever it wants usually it's 40 to 20 mph, you cannot go any faster, and there is no warning to this at all, and no pattern as to when it will do this. but it has always done it while i have been driving. this is not the first time that this has happened and luckily no one hit me that was behind me. i have had my truck into a dealership five times, the first two times was to mills in richwood, which they had no idea what to do with the truck as the engine wasn't throwing a code, and they thought it was a bad sensor but didn't know which one so they sent me on my way. the third and fourth time i took it to roby's. the third time they replaced the battery and said that was it, the fourth time they called gmc and said my engine needed a new code in it. two weeks after that the reduced power light comes on and i almost get killed on the freeway. i then took it to chesrown and they replaced a sensor in the accelerator pedal. no one knows what the problem really is and i'm scared to death i'm going to get killed because my truck does this all the time without warning and the problem is getting worse as before it would be almost half a year to a few months between problems, now it's getting to be every couple of weeks. this has been going on since i bought the truck in may 2006 and i am terrified to drive for fear that the reduce power is going to kick in and someone will be behind me when it happens and hit me and kill me. *tr | |||

| 2006 chevrolet colorado has a known defect with the camshaft actuator solenoid filtering screens dislodging from the part, that causes the engine timing to be affected and makes the engine idle rough and stall. this can create an incident or accident if the involved vehicle is in operation at the time of failure. *tr | |||

| After several weeks of check engine light going on and off i decided to have the truck checked out. after dealer ran history, stated that i needed to bring truck in for a head issue. after having the truck for three days, dealer notified me that they put engine back together and got it fired but was losing compression on the #1 cylinder. then the engine was making very loud noises. after tearing engine back down, then noticed the exhaust valve was stuck in the down position, while the piston was going in the up position, it broke the piston in pieces and broke the valve. the dealer contacted gm as to what to do. gm is sending a new engine to replace the blown engine. there is only 25,000 miles on the truck. *tr | |||

| 2006 chevy colorado 4 cyl. 2.3l camshaft position acuator 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. | |||
