I have a 2006 Hummer H3 (25k miles) with the same L5 3.5 engine as the Colorado / Canyon and the cylinder misfire problem. My GM dealer is running a leak down test tomorrow. I sent a separate email to you with my VIN. I hope you can help us! Thanks in advance.
Almost all Seals always leaking
4x4 modulator went out because of failure of the ingeniering of the water drain in the windshield
leaf springs broke with a small atv in it
drive shaft broke and transfer case had been changed
emergency brake had been replaced three times
check engine always on (misfire code and something about the gas cap)
I'm in Canada and i also have problems with the brakes in the winter
This morning its running on three cylinder and don't ask me why
cause my answer will be is not a good truck at all. Maybe if you use it as a car and your eighty years old and you live in california Maybe. I wish they fired the ingeneers that build this truck. It would make me fell better to know that.
N.B These are not all the troubles i had with that truck
thanks Lewis
2. Gaskets, Seals, Brake Sensors, Ignitor, ABS Fault issues, and the last one for me "A broken transmission".
3. Chevy dealers are good only on Sales Department, Service just sucks, seems to be that they don't know what's going on, or just try to extend the time you have with the problem ultil the warranty expires.
4. Original brakes last only 4,000 miles. And any noise close to your wheels Service Dept. just said are the brakes.
5. I didn't use the "truck" to work, just to get my daughter's bike and eventually carry a new furniture from IKEA. Only 42K miles on it.
6. Maybe they should buy the parts from Japan and send them to Canada or Mexico to put them together.
What was the solution: I SOLD THE CAR AND I JUST GET A HONDA RIDGELINE, for my needs it's perfect. :shades:
I am sorry that your Colorado has not been satisfactory vehicle for you, and understand how inconvenient it can be to have made multiple repairs. From reading your post, it seems that your current concerns are with leaking seals, the 4x4 modulator, leaf springs, an illuminated check engine light, and brake concerns. It may be worthwhile to get into contact with GM of Canada, who can be reached at 800-263-3777. I would offer to assist myself, but as I am based in the United States, I'm limited to assisting U.S. drivers.

Thats just an example, the bill has many more weird things and services including to replace fuel cap0 and the vent valve $179.20 for ctc5, $33 for cap, another $232.88 for f-valve.
p0449, p0445 scan code. They said they discovered vent valve shorted and gas cap leaking?
In total they hit me up for $1160.68 in labor charges, another $836.14 for parts. for a please pay total amount of $2146.58. This just seems out of control. Can anyone please just give me an idea if any of this sounds accurate or if I got taken hard. The car went into the shop at 1pm thursday and they said they finished it and let me pick it up at 5:00pm friday. So car was only in shop for a total of 28 hours. PLace is only open til 5pm. So they were not working on the car for 28 hours straight. How do they come up with $1160 for labor? Any help or input in the matter would be greatly apprieciated. Thank you
My dad bought his 2004 colorado 3.5 4x4 new from Valley Chevrolet in Wilkes-barre, PA. He has been having a misfire issue, also throwing codes. He had it to the dealer but it did not throw a code for them. It idled rough but said since no code was thrown, they could not diagnose. Truck had approx 60K on it. Now it has just over 80k and he had it to local garage. They swapped coil and problem stayed with cyl 2 i believe. The plugs were changed and several tanks of fuel were through it. He doesn't have the recepit from his vist to the dealer, but does the dealer have to honor warranty since it was in there previously for same issue?
We just saw all the issues others are having concerning the exhaust valves and seals.
Thanks,

This is a very good and fair question. For the 2004 model year, Chevrolet vehicles had the Bumper to Bumper Limited Warranty for the first 3 years or 36,000 miles that the vehicle was in service. The Powertrain Limited Warranty wasn't applied to Chevrolets (and other brands) until model year 2007. As the vehicle was out of warranty on mileage at the initial visit, and presumably time, a warranty repair isn't likely. I know this isn't necessarily the answer you were hoping to hear, and I apologize.
However, if work were to be performed at one of our dealerships, or if parts were to be purchased from us for repair elsewhere, there are warranties that would come into effect. If you would like more information on that, please let me know!
All the best,

The Federal Emission Performance Warranty on a 2005 GMC is contingent upon whether or not an EPA-approved inspection and maintenance inspection is enforced in your area. We would be happy to check into the coverage on your vehicle (sometimes can depend upon where the vehicle was originally sold) if you were to send us an email with the last 8 digits of your VIN.

Had similair issues. Traced it to the throttle body. What I learned is the Colorado intake system is very sensitive to any kind of debris build up in the throttle body. Now I just repace the throttle body every 50K miles and it seems to take care of that and other issues. Part is about $280. Make sure to buy a new "o" ring gasket for it.

They could not replicate problem, fuel pump pressure was good, fuel filter dirty enough to warrant changing. In all their fiddlin with it they got one code once (did they say crank sensor?). They took off an intake hose and shined light in to TBI and showed me carbon build-up at top, and while not claiming that was the root of problem, are recommending fuel injection system cleaning for a couple hundred bucks and I will probably authorize that. Someone online here mentioned AC connection to all this ... I do believe mine was off the first two times today when it stared, and that I had turned it on at mid-day before it did not start. This is where I am at this point.
So while I do agree with you that they shouldn't charge you $100 bucks just to READ the code, if they are charging you $100 to diagnose the actual problem--such as testing the 02 sensor, etc) and isolate the actual defective component, then that's fair enough.
San Diego GM dealership:
PCM: $410.00 , core $75.00
Programming: $108.00
Labor for R&R of PCM: 1.5 hrs at $108.00/hr
and of course tax at 7.75%
If we can ever be of assistance, don't hesitate to get in touch via email.

The "C" note they're charging is the 1-Hr[or whatever] minimum time.
The code P0785 is pointing at a "Shift/Timing Solenoid Malfunction"
The code PO2610 is One digit too many for the OBD-II system, you did a typo, or the dude gave you the wrong code
The code PO261 says the "1 Cylinder I Injector Circuit Low"
As said previously, WHY these codes are showing up is a matter for a trained technician, a GM Service Manual and a Quality Scan Machine.
Several Non-Obvious issues many mechanics miss.
1st -
I coined "Invisible Corrosion" a condition where the connector male and female terminals ARE tight yet fail to conduct. Sometimes a Lacquer or Varnish like Clear coating will form, preventing flow of electricity.
The previous condition is often caused by so called "clean-up-shops" spraying that clear junk all over the engine in an attempt to make it look new, inadvertently making a mess of the electrical system.
2nd
Poor "Mechanical Joint" in the plug, some techs overlook this issue which is VERY prevalent on Fuel Pump wiring harnesses on most GM's
3rd
Poor Grounding. Many electrical faults are due to faulty grounds.
Causes,
#1 - Rust or Corrosion from Battery Acid Vapors.
I separate the 2 because Battery Vapors cause corrosion in some unusual places, not just under the battery.
#2 - Paint under the lug, Even the factory will place grounds on painted areas, and especially Body Shops after wreck repair.
#3- Poorly Crimped Lugs,
GM introduced copper coated "Aluminum" battery cables with a 2-ear lug, instead of the "barrel lug" These were notorious for sounding like a bad battery or bad starter on very Hot days.
Other lugs are crimped with NO grease, soon to corrode, thanks to all the Big-3 for these issues.
4th
Insulation breaks in the wires.
The voltages in modern sensors go as low as 1.5 VDC,
[ that is AFAIK per my newest GM Service Manual]
A tiny crack or cut in the insulation can allow water intrusion, then Corrosion builds up on the wire, SIGHT UNSEEN.
As a near 40yr Electrical Generation Employee, the rule of thumb is that electricity flows on the OUTSIDE of the wire, not the inside.
I found this while working on a 91 Roadmaster S/W.
The ATS sensor [Air Temp Sensor] showed bad. The car would suddenly lose power at Interstate Speeds, nearly die, then chuuggg along, barely running.
I replaced the ATS, which in that 305 TBS system, is in the air cleaner.
NO Good, same issue.
Checked the wirings' mechanical fit, checked for the proper voltage and ground away from the plug, all Good ?? [Scratching Head]
The issue was sporadic, which of course made it harder.
A close inspection of the wires revealed that someone had closed the breather lid on one of them. At that point was a minute crack in the insulation.
Peeling off the insulation showed GREEN corrosion. The wire was SOLID AND INTACT, the mere presence of corrosion caused this fault.
I cut out 2" of the wire, used Heat Shrink and 5% Silver Solder and all was well.
Once a car with 4-Headlights had all 4 beams Lit Up on Low beam yet very very Dim?
Checked fuse with VOM Meter, Fuse showed Good.
The final solution, in that time cars had round fuses, the fuse was cracked below the metal contact area.a tug on the fuse, and it fell apart!
New fuse, all Good!
[This situation is called "Back-Feed, something most guys who pull trailers with NO Ground wire find out quickly]
All the previous drivel was my attempt to show how even the OBD-II vehicles and modern scan tools do not make wrenching Easy!
Most Sincerely

Good Luck and take a $3 sack of Apples for bribery and be nice, it will help.
Eventually, after changing fluids, etc. I pulled the code and it was P0017. My independent mechanic put the motor on his diagnostic stand and couldn't find anything wrong so we started replacing sensors. After replacing all three sensors (he paid for the third one himself) we were at a loss as to what was going on. The light would come on, stay on a few days, and then shut itself off, then come back on again.
The radio in the truck had been replaced by the Previous Owner with an Alpine unit using the wrong mounting hardware so the panel in the cab stuck out slightly. Our next hypothesis was that the radio had been inavertently wired into the "data line" of the wiring harness which carries 12v instead of the correct terminal associated with the ignition lock, etc. since the radio operated completely independently of the key. Partly so I could play MP3s off my player in the truck, I replaced the radio, planning to get a report from the techs regarding the wiring of the old radio, but they got away from me and had it installed and working correctly before they even thought to note which line the old radio had been using. At any rate, replacing the radio gave me a working clock and now the radio shuts off and on with the key as expected, and I can listen to my audio books while driving around with the "P0017" check engine code still showing.
By this time we had cleared the check engine light and code about 12 times!
The other day I got out on the expressway, set the cruise at 70 and blew about 8-10 miles down the road to pick up some stuff. When I came out of the warehouse and started up the truck it was on. I stopped briefly at the foot of the driveway to make a phone call, and when I restarted the truck, it was off and so far, fingers crossed, it has not come back on.
My latest hypothesis is that this particular truck was left "sitting out" for quite a while without being driven and possibly without an oil change in more than a year. A bit of sludge might have been interfering with the hydraulic variable valve timeing and setting off the code when I started the truck up cold. Note that I was only putting 5-6K miles a year on my trusty old Ranger so I don't run this truck every day and most of my driving is short hauls on surface streets. I don't know what function switches the check engine light back off, as I thought that once the code was set the light says on, but my own experiences say that isn't quite the whole story.
When the light comes back on, what do I look for next? Do I need to try and "wash out the engine" the next time I change oil? Is there a known "glitch" in the on-board computer which makes it hyper-sensitive? I'm assuming that my motor is far enough down the line from the original 2004's that bad valve springs isn't the likely issue. :confuse:
Any ideas on what I can do? His resources are very limited.
Thanks a bunch

BAIL OUT !!! BAIL OUT !!! People they were only trying to tell us to BAIL OUT!!!
They know they have a problem and what have they done to fix it ?????
GM made our government responsible for there finances / they should have looked after ours and let that big ship sink, it would have sent a powerful message to big business to bring quality back to North America!!!
BYE BYE GM BEST OF LUCK TO YOU!!!
I know that vehicle repairs can be frustrating, but it sounds as though your mechanic was able to narrow down the source of your concerns. I see that you're using kilometers as your unit of measure and am guessing that you're writing from Canada; if you had wanted to speak with GM of Canada (Customer Assistance) they can be reached at 800-263-3777 (Hours: M-F 7:30am - 11:30pm, Sat 7:30am - 6:00 EST). I would offer to look into this further myself but am unable to assist customers outside of the United States.

I just gave my local chevy dealer the last check I will ever write for repairs to a Chevy vehicle.
It just cost me $567.80, for a check engine light and A/C problem, that returned the next morning, and be told to have it towed , we'll check it again.
After going again I was told its mass air sensor , that we wont have till tomorrow, but you can drive it till then.
Hopefully its not the know issue with the valve intake leak, which they don't even mention. I just want to get it running so I can trade it in for a Nissan Titan.
I have bought maybe 9 or 10 new Chevies over the years, this Colorado will be my last.
Good Bye GM , I can see your on your way out. Please just close up , don't screw millions more before you close your doors. All of your engineers should be fired anyway, they are useless!
Sarah, GM Customer Service
I have a 05 Sante Fe i bought because of a very bad experience with a Venture. In the 7 years I have it , only put on tires and a set of brakes , in 60,000 miles. Never a problem. Now I gave the vehicle to my daughter , she still drives it no problems. My wife liked the Nissan Rogue, we have that 2 years now , never a problem , and just had it serviced , oil change , check all fluids , rotate tires and 32 point check. Bill was $21.19.
Had trouble with a Lumina, s-10, APV, Venture , and Colorado.
Why would I ever consider GM again!
Good luck with your Ford.
It work so great no more check engines and expensives problems I'm so happy now.
