#342 of 399 Re: Does anyone know? [tvukelic] by redneckwoman71 Apr 02, 2009 (7:03 pm)
Replying to: tvukelic (Mar 20, 2009 2:53 am) Just happened to find this forum because I was wondering if anyone else has had problems with Colorados. My husband bought me a new 2006 Crew Cab that I absolutely loved body wise because I am 5'2". But we had nothing but trouble out of it since day one. It started out small, power windows messing up, etc, but then a month ago the cab filled with the smell of antifreeze. Turns out it was a leak in a heater coil. The dealership fixed it with no problem because it was still under warranty. But we could not get the anti freeze smell out of the cab. Well then, twice this week we had some major smoke come out of the exhaust when it was started. We hadn't read about all the problems with the heads on these trucks, but we figured we were getting ready to have a major problem and with only 1000 miles left on the warranty, we worried if we waited around too long we would be screwed. To make a long story short, we went today and traded for a 2009 Silverado. I was hesitant at first because of my size, but after driving it home, I absolutely love it!! I loved the size and look of my Colorado, but it just wasn't worth dealing with all the problems. My advice: DON'T BUY ONE!

I have a 06 Colorado 4cylinder, I have had it for a couple of months and noticed when I run the A/C it smells very musty. Any solutions or experience with this. Mike Replies to this message: Mr_Shiftright (Apr 11, 2009 6:58 am) dmathews3 (Apr 11, 2009 12:01 pm)

Replying to: texas914 (Apr 11, 2009 4:49 am) it's mold in the AC vents. You can find various sprays online or in stores that deal with this but in extreme cases you have to take the vents out and wash them, and sometimes dig into the heater core area as well.   One good habit is to run the heater through the vents now and then to dry them out.   I've heard that changing the cabin filter (if your vehicle has one) might help but I can't verify that one way or the other. Unless it proves to be moldy itself, I rather doubt it would help. Replies to this message: dmathews3 (Apr 11, 2009 12:01 pm)

Replying to: Mr_Shiftright (Apr 11, 2009 6:58 am) another prevension is to run AC on normal mode the last 10 min. or so if you are using the recirculate feature a lot.

Replying to: bearsrnum1 (Apr 17, 2009 2:43 pm) If you have a voltage drop during engine cranking, this may cause this very thing to happen.   You should read the code set by the ECM. If it has anything to do with the throttle this is probably what happened.   You should load test your battery or if it is the original, just replace it, reset the codes and see what happens. Don't replace any parts yet.

Replying to: chevydetective (Nov 13, 2006 11:54 am) i've had this same problem. with my 04 colorado i would use my key remote to unlock the doors but it wouldn't disengage my fuel lock on the engine so it would turn over just not fire up i've had to get my key remote reprogramed twice so far because of this problem and i have had to pay for them to get reprogramed. if i get the problem one more time which i feel will happen again because the last 2 times have been within the year so far im gonna try the lemon law thing

The problem with my truck was that the crank sensor was bad. After it got replaced everything good.
#350 of 399 Engine electrical component failures by russ95 Jun 08, 2009 (8:00 am)
Hi,  I have an '04 Canyon 2wd 5cyl 5mt with 112,000 miles. I have come to realize that most of the electrical issues with these trucks such as coils, blower resistors & blowers, switches, sensors, door electrical problems, lighting problems, idle speed, check engine, and some no start issues can all be caused by the high amperage flows that are created by low system voltages.  There seems to be (my opinion) two main causes. First is the marginal capacity Delco battery. If you are willing to eliminate the battery enclosure a much larger 850cca group 65 battery (Costco $80.) will fit in the stock retainer system. If you don't idle for long periods with the blower on high or other unusual high electrical demand (at idle) a battery upgrade may be all that is required. If that isn't enough you could consider changing from the stock 100amp alternator to the upgraded 125amp alternator used on the 08-09 4&5cyl trucks which seems to have resolved all these problems. Remember that no alternator will provide much output at idle speed. Good Luck, Russ
#351 of 399 head problem way out of warranty by rtroy66 Jun 10, 2009 (10:45 am)
I was in arkansas visiting family when my engine light came on this last saturday, June 06 and so I took it in on Monday the 8th and they told me that the problem was the engine was loosing compressing due to faulty seat. Well I travel a lot and at 150,000 miles they told me it was going to cost 2200 dollars to fix it. Couldn't I just put a new engine in the truck for a little bit more. I don't know, but I think this should have been covered in the recall regardless of mileage.
