2 cylinder bad. Runs rough w/engine light on. Significantly more gas usage. It'll be $3500 to fix the engine intake valve seats with head replacement, and there'll be no cost coverage by Chevy. What?? The dealer says the "campaign" to rectify this known problem was over for 2005 models in 2012 (7 years or 100,000 miles, whichever occurs first), but they'll "work with us" and will give us a $250 discount. Ha ha. The bulletin GM sent out in August of 2007 says not to take it in for repair "unless you believe that your vehicle has the condition". Well, it didn't have the problem until Fall of 2015, and now they won't do a thing about it. How convenient for them.

My hubby has owned 3 Chevy trucks in a row. He's been a loyal customer. Loyal customers don't deserve to be rewarded with this sort of rip-off. He has kept the mileage low and babied this truck inside and out from the start, but now it's toast because of a known factory engine fault that Chevy won't acknowledge with an actual recall?

We're not paying Chevy $3500 for their problem engine. We're getting rid of this lemon and are buying Dodge, Ford...anything but Chevys from now on.

I am a self employed window washer working 24/7 I have no time for car problems, so I invested in a new Chevy truck in 2005. To my disappointment this Chevy product has run maybe 300 days out of 10 years of ownership without a problem, starting with major problems in the first year. Recall head, smaller problems; stereo speakers, crank window handle broke how do you break a handle). Before 35000 miles had to replace back brakes and shocks (front brakes I understand) belts and battery airbag light already started coming on, back door cut electric wires to stereo and indoor lights before 60,000, air conditioning control broke, manifold cracked (how do you crack a manifold). Had to replace carburetor injection (no sure of the mechanical term but expensive)..I can rant and rave forever, needless to say I am giving this losing cause away at 135000 miles. They want another $3000+ to fix the timing chain and carb problems.

Shame on government bailouts to company's that produce SH*T I didn't get one. Thank goodness I have Toyota's to back me up. BTW Toyota is more American than Colorado's made in Korea.

BS, Chevy got it all bailed out, they have lots of new roll outs which suck. I work in the auto business and have never been a Chrysler fan but in this instance I own both. I've been raised to be a Chevy guy always "f*ck ford". I've lived this my whole life with the exception of a Honda wagon which was junk and a tc mini. The Town and Country has had the water pump, alternator, ac clutch, ac compressor with clutch, power steering pump, new pulleys. The Chrysler being an 04 the Colorado 05. And the difference I knew what was wrong with the van. My truck threw 13 codes ran with engine light and abs light on since I bought it with 40,000. Van runs like a new one. Truck has 85,000 idles like sh*t, stalls out at low rpm. I've put more into the truck than my 1990 Cadillac.

Engine was idling really bad. Did a full tune up, still the problem remained. At some points the motor turn off while driving. I had to send it immediately to the mechanic and after a full diagnostic, they advised the fuel injectors needed to be changed.

My uncle a mechanic was looking for the cause of the check engine issue...he had me take this in under the bulletin to the Chevy dealer. In order to cover this properly they wanted me to do a series of COSTLY things - at which my uncle did. Checked compression, changed plugs ---total clean out/flush --the hole nine (by now I have forgotten the details of what all he did to satisfy their stupid rule. . by the time he finished, it ran good for about 6 months. After which - everything started back up again. Misfiring and throwing the check engine light on. SO I take it to the dealership - they said my uncles work didn't count because it wasn't done at a dealership. So I was back to square 1. And at that point I was about 30 miles over on mileage. After searching the issue i have seen SO many people have this issue and GM knows about it based on the bulletin. Stating it was faulty! Why should we have to pay for a faulty part, no mater how many miles are on the vehicle. GM you need to own up and replace these...NO MATTER HOW MANY MILES

After replacing the spark plugs and #2 ign. coil and clearing the code the check engine light came back on. I'v since cleared the engine several times and after a 30 to 60 mile drive the light comes back on. It runs rough at idle. Has any one had this problem?

  • Automatic transmission

Well the sensor above the gas tank to prevent overpressure is loose. Well, it has always been loose. When Chevy built the truck they forgot to install the harness to hold it. The wires have since snapped and the check engine has come and stayed on. Taking it to the dealership and was told there is supposed to be a harness there. They will fix it but will cost me for Chevy's over site.

I love the truck but I've only had it for around 9 months and my service engine light has come on three times for the same problem. When i take it to autozone to get it checked they tell me that its from lean gas and ask me if i filled my gas up recently. Its off right now but for how long?......nobody knows!

Update from Jul 30, 2010: After going to autozone a couple of times and getting the same code from their computer I decided to look up on the internet myself what the code meant and sure enough it ended up being an oxygen sensor. I replaced the oxygen sensor myself and havent had a problem since.
