#372 of 717 brand new 2009 Chevy colorado 2.9 exhuast, engine issues
Sep 05, 2009 (4:23 pm)
I just bought a 2009 Colorado LT1 with the 2.9 engine as part of the cash for clunkers, It has a total of 1200 miles on it. I had to take it in to the dealer already because it was back firing and they said there was a service bulletin about the exhaust seal between the caytiltic converter and the muffler. They fixed that but I'm still hearing a noise like a low farting (for lack of a better discription) noise when I accelerate. Also I have allot of carbon buildup in the tailpipe when its seems like there should be next to none at this point. Finally its shifting poorly on the highway, it seems to gear back and forth between 2nd and third harshly when pulling into traffic. I cant help but this this is related somehow to the engine, possibly a torque issue. This is my first ever new car, I have service my own cars in the past and if I were to guess Id say it has a bad exhaust valve but I know these new engine are complicated.
Generally its running ok. It seems to idle a little rough. Im going to take it back to the dealer later in the week. If there is anyone out there who has any information regarding these issues please let me know. Im hoping I didn't just trade in my Clunker Safari which ran till the wheels were falling off for another brand new clunker.

Carbon build up sounds as if it's running very rich. They should check your fuel system. Don't know about the tranny. Maybe related thru the central computer.
#374 of 717 Engine miss and check engine light on
Oct 14, 2009 (4:46 am)
I have a 2004 Canyon with 46,000 miles with the L5 engine. I had a engine miss and check engine light was on. I have a friend that is a GM tec and he put the scanner on it and we found #1 cylinder was missing. I already put new plugs and the head was replaced at 26,000 miles. We also looked on the factory GM repair database site and noticed that there were MANY problems with heads and fuel injectors. I decided to take it to Jim Lupient Chev in Bloomington Minnesota where I bought the vehicle. They called me and stated that #1 and #3 fuel injectors were bad and that it would cost me about $1300.00. I asked them about the oil consumption and they stated that it could be a blocked passage in the valve cover and that would cost me about $450.00 to have them look at that. I told them no on that repair. Called me 2 days later and told me my vehicle was done but now #4 was bad and that it would of cost me additional $940.00 if they had replaced them when the did the original repair. Got in a argument with them and left. Got a block away and the check engine light came back on! Long story short, the dealer and regional GM service told me to bad. I am writting many letters!! GM charged me $218.00 per injector. I decided to fix it myself. I found NEW injectors on Amazon for $85.00 each. Was not a easy job but it took me about 5 hours to do the complete job. It runs good now but I might just be driving it to a Ford dealer and buying a quality vehicle from a company that does't have all our money and even more of mine. GM either makes junk injectors for this vehicle so at 46,000 mile you need to spend $2300.00 to GM to replace them all or the mechanic needs to learn his job. I beleive its the first. I will never buy another GM and will never do business with Lupient Chev of Bloomington Minnesota.
Good luck all!! GO FORD!!!!!!!!

Has anyone noticed that the plant that builds these trucks (Shreveport, La) was not transferred to the "new" GM company that emerged from bankruptcy? I think that says a lot about this plant and the quality of the product. The "old" GM exists only to sell off the assets that the new GM does not want.

I don't think this has anything to do with the quality of what the plant builds. The H3 Hummers are built there and are being sold to China company and will only be built for 2 years. The Colorado has been around in this style for about 5 or 6 years and my guess will be phased out with the hummer and the new small truck will be built in one of the current plants that will hav room as Saturn and Pontiac goes away. The people who work at these plants can only build with what they are given and in the amount of time they are given to perform their work. I had a Colorado CrewCab for over 4 years without a major hiccup as has many many thousands. For the most part the people here are the minority who have a problem or think they have a problem. There have been many who have bought this vehicle or another vehicle USED and then blamed the manufacturer for not producing a quality product even though they have no idea who owned it before or how/if they even took proper care of it.
#377 of 717 2006 Canyon Reduced Power
Oct 19, 2009 (7:34 am)
My wife and I bought a 22,000 mi 2006 Canyon from the original owner in May. The REDUCED POWER and EMISSIONS lights came on a few months ago. I pulled over and restarted the car. The EMISSIONS light stayed on, and as there was less than a 1/4 tank I thought it might need some clean gas. After filling the tank the EMISSIONS light didn't come back on. But last week my wife used the truck early in the morning and she told me after that the REDUCED POWER light came on for her and the truck wouldn't respond. A master mechanic friend at a local gas station did a free diagnostic and found the report: P2138 ACCELERATOR PEDAL POSITION (APP) SENSOR 1-2 CORRELATION. He said it was a sensor for the gas pedal or perhaps the whole pedal unit. I took it to the Morgan GMC in Shreveport (ironically) where our other friend purchased it, and they want $95 just to do the diagnostic and at least a few hours wait just for that. So I said I'd come back. Instead I am researching it further here....And the Morgan dealer service rep informed me that the manufacturers warranty had run out in April 2009...we bought it in May. The seller said it ran great. But I am wondering if our seller "friend" may have had the signal as well. (I can't call it a "problem" yet as it has only happened twice.)

Has any one had a problem with the welds breaking at the exhaust manifold and pipe. It happened today coming from work. I hit a bump and went from quiet to race truck. Called the dealer and they wanted to replace the exhaust manifold and I asked is the pipe already welded on and he said he didn't know ???????? So I called a muffler place and there going to look at it tomorrow. He said if he can get in there to weld he'll do it. I hope he can..........Zippy

I would do further diagnostics. If there is something wrong with the emissions system (catalytic convertor, power module, etc.) it's still under the emissions warranty which runs for 5 years (?) or 80,000 miles (?). Check your warranty booklet for the items covered by the emissions warranty. I had an S10 that was over 4 years old and had over 70,000 miles and the catalytic convertor was replaced free of charge because it was covered by the emissions warranty. Good luck.

Well no welding. Theres another converter thats apart of the exhaust manifold. They got to replace the exhaust manifold which will cost over a grand. The warranty is 8 yrs/ 80,000 miles. I got over 85,000. SUCKS. This is the first time I had to sink some money into this truck, so I feel pretty good about it. Hope this doesn't start a chain reaction.
