    It sounds like the head problem to me also. I doubt a lemon law would apply at this time.

    If you have this documented at the dealer and is not resolved in time, you still should be safe after experation.
  • This is such a common problem, everyone is aware of it. If your dealer pretends not to be familiar with it, he is either a liar, or way to uniformed to bother with. No matter how inconvenient, take it to another dealer that has a clue. I'm guessing he is aware, just trying to be a hero. Go to someone who cares about customers......
  • I HAVE 04' COLORADO 4X4, CHECK ENGINE WAS ON AND HAD VERY ROUGH IDLE. TOOK MY TRUCK TO HARBOR CHEV. WITH MY LETTER WHICH THEY SAY THEY HAVE NEVER SEEN BEFORE. THEY CHECKED THE CODES-P0303 CYL. 3 MISFIRE AND P0506-IDLE CONTROL SYSTEM LOW,RPM LOW. THEY WANTED TO PART SWAP TO SEE IF A NEW $400 THROTTLE BODY WOULD FIX THE PROBLEM. I SAID I WOULD BRING IT BACK. WENT TO AUTOZONE USED THEIR CODE READER AND GOT A PRINT-OUT. THE CLERK SUGGESTED A $4 BOTTLE OF CLEANER AND A GOOD CLEANING OF THE THROTTLE BODY. I DID IT AND IT WORKED FOR THE ROUGH IDLE. BUT I STILL LOSS OF POWER, LOW GAS MILEAGE AND #3 CYLINDER STILL MISFIRING. TOOK IT TO CHAMPION CHEV. IN L.B. CA TO CHANGE FUEL FILTER AND FUEL INJECTOR SERVICE AND GAVE THEM THE CODES. THEY HAVEN'T SEEN THE GM LETTER EITHER. THE WORK WAS COMPLETED AND EVERYTHING WAS RUNNING GREAT SO THEY SAID. I WENT TO START IT UP AND LEAVE AND THE ENGINE LIGHT WAS ON ALREADY, DROVE 10 FT. TO THE SERVICE TECH. ED AND HE SENT OUT THE MECHANIC WITH HIS DIAGNOSTIC READER. HE TOLD ME THAT I PROBABLY NEED A NEW CYLINDER HEAD BECAUSE OF THE MISFIRING AND NOW A NEW COMPUTER BECAUSE IT WENT BAD WHILE HE WAS HOOKED UP TO IT. NOW I AM TAKING IT BACK IN TOMORROW FOR THE WHOLE WEEK. AFTER HARBOR CHEV. I CONTACTED GM CUSTOMER SERVICE AND I HAVE BEEN DEALING WITH PAUL GRANT (866)790-5600 EXT. 31502 BECAUSE HARBOR CHEV. TRIED CHARGE ME $99 FOR THEIR MISDIAGNOSIS THAT WOULD OF COST ME $400 THAT WOULDN'T HAVE FIXED THE PROBLEM. WELL I DON'T OWE THEM $99 ANYMORE BUT I AM NO LONGER ALLOWED ON THE PREMISES, TOO BAD. I ADVISE ANYONE TO CALL PAUL GRANT, IT MIGHT LIGHT A FIRE UNDER GM'S BUTT TO GET ALL THEIR DEALERS TO BE HONEST WITH THEIR CUSTOMERS. ANY ADVICE ON GETTING CHAMPION CHEV. TO FOLLOW THROUGH AND REPAIR THIS AT NO CHARGE.

    Take it to a different dealer, If the truck has less than 100,000 miles on it, and the dealership finds that it is the valve/cylinder it should be covered under warrantee. GM mailed out letters to alot of people with older Colorados extending the warrantee to 100,000 miles. I believe somebody posted a copy of the letter earlier on this same thread.
  • My 04 Colorado is in the shop. I got a letter from Chevy stating because of bad valve seats (same symptoms as yours) they would put a new head on if under 100,000 miles. I had 99, 650 so I went direct to the dealer and sure enough, they said I qualified. Now they say they are rebuilding the head instead of a new one but hey, at 100,000 miles I guess it's better than paying for it!

    No one could diagnose problem before, my local mechanic wanted to
    "service" injector system at $700 bucks! So I'm happy, it wasn't a major problem, just a pain for the light to come on and off with some rough idle at times. I like the truck, I tow my 19' Bayliner with it as well as my pop up tent trailer.
  • I had the same problem. It's a security problem probably triggered by a faulty ignition switch. If it "senses" something wrong, the car will not start for 10 minutes. Look at the dash panel, you will see a flashing "lock". It's mentioned in the owners manual. Mine did it a couple times a year until it finally quit doing it. I've got over 100,000 miles now.
  • That's good, GM stepped up.
    I traded my 05 Colorado even before they started working on the motor.
    And the trade in value was like my truck was in good running condition. I had 88,000 miles in over a year.
    I'm happy with my 07 Silverado LT. I get good mileage, 22/23 mpg, if I don't go over 70 mph. I also replaced my air filter with K&N. (not the kit).
    Good luck with your Colorado.
  • My 2005 GMC Canyon 5 cylinder with less than 20,000 miles has been in the dealer shop so many times that I fought and won an extended warranty. Cruise control malfunction, traction control issues, and cabin wind noise to name a few. The last straw was a head gasket leak. My latest troubles are an engine silouette check light that won't go off. Coincidentally, this occurred after I replaced my original spark plus with Bosch Platinums and a new K&N air filter (not the kit). The engine also whistles when I turn off the ignition. I am concerned the dealer will try to attach my self service to the engine troubles as my fault. Does anyone else have these problems?
  • tm4tm4 Posts: 19
    Wow, that sounds like you have a lot of problems. I haven't heard of any of these being common problems. I would like to say that Bosch Platinums are just about the Worst plugs you can put in any vehicle. I haven't had to replace my plugs yet so I don't know what the stock plugs are, but I DO know that if the stock plugs are not platinum, then you should not use platinum aftermarket plugs, this is actually one of the top 10 leading causes of Smog Check Failures in CA, and Bosch is the leading culprit. This could be the reason why your check engine light is on.
    Just know that if the Truck is brought in for the same problem more than twice, find a good lemon lawyer.
  • dmathews3dmathews3 Posts: 1,739
    A lemon lawyer won't do him any good as they are only for the first year and his is a 05.
  • I never went the lemon lawyer route. Dealing with the GM representatives were not easy. When they asked what they could do for me, I asked for a new truck. First, they act compasionate and interested. Next, you get passed up the ladder to different levels of seriously. GM also tells you to take it or leave it because I asked for a new vehicle. Eventaully serious negotiations start and you need to learn how to say NO two or three times. Perserverance brought on an offer of more or close to tripling my year and mileage warranty. Good thing I have it now. I drive cars for 150,000 miles or more. Never had this much happen before 20,000 miles.
  • tm4tm4 Posts: 19
    Lemon Laws vary by State. Some states the law is only good for the first year, but some states the lemon laws are good for as long as the manufacturers warrantee is in effect. I don't know what state you live in but the lemon law could apply for 3 years or 36,000 miles.
  • My 05 Canyon would not start this morning. I called for a tow truck. About 10 minutes after making the call went out to take personal things out of the truck. I decided to turn the key one last time and it started right up! I did notice the alarm icon flashing but I thought it was just because of the position of the key in the ignition. Glad I tried to start it again. It saved me a $78 towing bill!

    Thanks for posting your comments about the security. I was getting ready to replace my fuel filter thinging it may have gotten clogged up from the temp falling below freezing.
  • dmathews3dmathews3 Posts: 1,739
    I have an 04 Crewcab 4 X 4 and want to change out the fuel filter as to take it to the dealer would be a 1/2 day job plus of course top dollar. Where is the filter on the Colorado located?
  • The fuel filter on the 2005 Crew is under the Cab on the inside edge of the Main Frame beam. I did mine in less than 15 minutes and I don't remember having to use any tools. I may have used a screwdriver to assist with a clip but it was very simple and the filter was less than $20. I hope this helps. I used an aftermarket filter from NAPA.
  • dmathews3dmathews3 Posts: 1,739
    Thanks and if I may ask, drivers side or passenger side. Being I'm in Mich. and it's cold and a little snow on the ground I don't want to hunt all over for it.
  • Eh, not so fast. I bought an '07 about 11 months ago (Feb '07) brand new. Had it in the shop four times in the first three weeks for service bulletins, recalls, and starter issues. I've had to take it in at least four times since then for various issues as well, including a computer program error that currently has no fix, causing the check engine light to come on, the truck to run rich, destroying my mileage, and I had the injectors plug up at 35k. The dealership finally corrcted the problem best they could without the fix, it's behaving now at 38k, and the service manager assured me there's a case file with Chevy on my truck so that if the problem occurs again they can fight to have it covered even though my truck is now out of the origional warranty (Thank God I purchased the 5 yr/100k warranty when I bought the truck!). But now I have a wiring issue in the rear end brake lights that may or may not be related to the post-accident repairs they did last month, and I highly doubt Chevy will cover the $200 ticket I got last night that clued me in to the fact my brake lights were out. Now I have to sort out a ride to work til the dealer can see my truck tomorrow, which is involving my mom having to get off work early to take me in, and my bf picking me up to take me home (clear across town!) at 3am. Once I get this truck paid down I'm seriously considering trading it in on something else.

    Are you sure your truck is an 07? Because (correct me if I'm wrong) the 100,000 mile warranty came standard with all 07 models, it was 06 and older that came with the 36,000 mile warranty. Also, if you were in an accident and your tailights stopped working, I don't think you can blame GM, you should go after your insurance company for not repairing the damage properly.
  • '07 is what it says on the title and all the paperwork from the dealership. As well as the window sticker. I know mine was a pretty base model (AC, cruise control, and an AM/FM sterio were the only "frills" it came with). And all the conversations I've had with the service department seem to say it only came with the origional 3/36 warranty, and I had to purchase the 5/100 as an extended when I bought the truck (which I did).

    I won't know til the dealership looks at the truck tomorrow whether the taillight issue is related to the accident or not. To the best of my knowledge the only damage was to the towing wiring harness and the bumper itself. I have had to replace bulbs about once a month since I bought it, which seems a little excessive to me. I've already ruled out the issue being the bulbs out, the harness being loose, and the fuse being out. So it's probably a wiring issue at this point, for damn sure I'm going to make them either cover it under my warranty or the insurance repair.
  • dmathews3dmathews3 Posts: 1,739
    Didn't the 5/100 come along a month or so into the 07 run and if you bought it before then I can see it but I would check into it by calling GM and not trusting the dealer. If so than GM should refund the money for the extended warranty. Also is it possible the dealer sold you the entended warranty that covers the whole vehicle which is an improvement on the 5/100 that is now standard as that just covers the drive train. At the rate you are putting on the miles that warranty isn't going to do you much good either.

    Sorry about your issues, that shouldn't be happening in a new truck. My 1992 S10 has never had any light bulb issues like that. In fact the only light bulb on the truck that has yet to burn-out is my passenger rear tail-light bulb, and the other one only once. Changing bulbs once a month or even once a year is way too excessive and it would cause me seek help/advise because something is not right. Your warranties should take care of these issues.
  • I have an ' 06 colorado crew cab last november the check engine light went on. I was working and I decided to take it to the dealer to check it out, and just when I turned the AC on it didn't work, it only blew on max, the other three settings did nothing. That day the service guy told me that it had a missed fired and that was a maintenence problem of some carbon over some place I dont remember, and he told me that I have to pay for it, and it was a $100 job. I told him that it could not be possible because I only put on tha same gas since I took it out of the dealer and I did all the oil changes every 3k miles.

    Nothing came throug so I had to pay for it. But the AC problem was that the switch wiring was defective, they cange it at no cost. Then I noticed thad it had less power and less gas millege. I still used it and suddenly the check engine light went on again, but this time I took it to a friend that has the computer and guess what, the same problem that the GM service guy told me. I called the GM service guy telling him the problem and the next day I took it to the dealer. Later that day they told me that there had been a promlem with the engine head and they have to replace some parts.

    Now I'm trying to get back my $100 for a bad diagnose.
  • dmathews3dmathews3 Posts: 1,739
    I agree, they should give you back your money and they should have known what it was in the first place since it is a well known problem. If they hesitate I would contact GM directly through their 800 number which should be in your owners manual. Worst case GM is sending back monies spent by people on this problem before they issued the buliton and sent everyone a letter in the mail.
  • I just head my head replaced at 72000 miles. All these vibration, mileage, power, idle surges are related problems. You must replace the head!!The only problem now is, they used a REM Head, now the problem is happening again. As far as Im concerned,, they bought my engine when they operated on it at that mileage!!

    In case you haven't tackled the filer replacement yet, it's on the driver's side.

    (I don't check this forum as much as I used to, just saw your post today)
  • I need help why is my engine light on it just came on this morning. I let it warm up in the morning times and I keep it check I just got a oil change about 3wks ago. Help please!!!!!!!!
  • poncho167poncho167 Posts: 1,178
    Rear some of the other posts. One simple solution sometimes is a loose gas cap. Other drivers say it can related to a bad head.
  • Do someone know of any recall, anouncement or web news about this I 5 engine problem? so I can take it to the dealer as evidence of GM recognizing it.
  • My son's canyon has engine problems, here is the number to call 1-866-790-5600. it is recall-06030. They will extend the warranty under special coverage code (07123). It is a manufacturing problem with the 04-06 canyons and colorados. They will have to replace the head and other stuff. His check engine light started coming on in November. He took it to the shop and they said it did not throw any codes. Since then it has came on and went off again about 100 times. Yesterday he was driving down the road and it died, he started it back up and it said "low power" it would not go over 30mph. Took it to the dealer, they hooked it up, said nothing was wrong. My son had taken a picture of the dash so he could show them what it said. Today they call back and said it needs the head and other things replace. GMC is supposed to pay for it all. We'll see!!!!
  • This truck is bad news. We bought it new off the lot. After many check engine lights coming on we have been told - nothing is wrong - they reset computer- no codes- reset computer - changed oxygen sensor- blah blah blah. Now at 77000 miles we took it to dealer because it is bogging down- no checked engine light. It dies at stop signs when warm. Took it to dealer--they said the valve springs are bad. But unless they are broke no warranty will cover. They wanted 1700.00 up front. If our extended warranty paid they would give us our money back. We took it to a local garage. They found a warped intake manifold. Bad injectors and now we are up to a bad valve. They sent it to an engine rebuilding shop - and came back with carbon deposits due to bad gas or gas deposits not burning properly. All things keep coming back to the check engine lights that never threw off the right codes and allowed the valves and everything else to be carboned and compromised. This truck has run rough from the beginning and no dealer could do anything!! Chevy/GM knows full well about this problem but find it cheaper to put people off until the warranty is up rather than do the recall they know is necessary.
