I bought this truck a little over 2 months ago. Since purchasing the truck the check engine light came on, I had to have the gas tank float/fuel sending unit replaced, I had to have the ac repaired because the ac would turn on and then constantly turn on and off at first and then it stopped working all together, I had to have transmission seal replaced because it started leaking, and now I have this awful vibration when I accelerate and I have to keep the window cracked open because the sound of the vibration inside the truck is so loud it makes me feel like my head is going to explode. I was not made aware of any problems with this truck as a matter of fact the dealer told me the truck had just been serviced, the oil was changed and there were no problems with the truck. I realize that I bought a used vehicle and it's not going to be in perfect brand new condition but this is ridiculous so now I am stuck with a truck that has many problems that Chevrolet has been obviously aware of since the beginning and I am out the money I paid for the truck. I can't afford to spend all this money to keep fixing this truck just for something else to have to be fixed. I was told that I don't have grounds to file a complaint based on the lemon law and the dealer won't let me trade this truck for something else or fix the problems so I'm stuck.

Vehicle will crank and not start, check engine does not come on. Wait 10 minutes and truck will start. Happens up to once a week, random. Took it to the dealership, replaced element, installed fuel system power pack, injection system clean and replaced air filter. That was in 2010, truck was under warranty but did not cover this work, did not fix the problem. Truck is no longer under warranty and still having the same problem.never know when it will happen.

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.

I have a 2006 Chevy Colorado with about 61,000 miles. I have recently had it to fail N.C. inspection due to dtc P0017. I have spent roughly $400 between sensors/valves and diagnoses for this truck. I see there are numerous tsb's for this model and dtc P0017 being a couple of them. We are struggling trying to get this taken care of and would like to file a complaint because we believe this is a defect due to the recurring problem people are having with this dtc code. There should be a recall. Please do something about this, so other people won't have to drain their bank accounts for a defective vehicle.

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.

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.

The consumer stated the air bag light did not turn on when the seat was occupied and sometimes the air bag indicator would suddenly show the passenger air bag was off. The consumer also stated on one occasion, the vehicle did not want to move; it went a very slow pace no matter how hard the accelerator was applied. The check engine light illuminated. The dealer stated they found a fuel injector leaking.

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.

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
