    Yeah, TOP SECRET. Just like the piston slap, which they apparently did not fix after all. This really irrates me. Why can't they come clean and basically say that they have no intention of producing quality vehicles and instead of a fix they will use Bandaids to merely delay the problem discovery?

    Somewhere here (or on the Canyon board) someone posted info about the 2007 Colorado/Canyon having increased horsepower (not increased displacement/# of cylinders, but maybe a software upgrade).

    Just wondering where that info was found, and if anyone knew how this HP increase would impact fuel economy (if at all).

    A small diesel does look like the wave of the future. It will probably come from Chrysler/Mercedes. The E320 comes out this fall, 35mpg and hopes to be 50 state legal using Blutec to clean things up, Jeep will be next.

    An Isuzu making 150hp and 350lb of torque doesn't seem possible.
    GM has a turbo diesel (not their eng) SUV coming out in Europe with 150hp, 310lb of torque at 2,ooo rpm that gets 29mpg.

    I forgot to mention the Diesel Beetle gets 37 city and 44 hwy with much less power numbers.
    The TDI diesel versions of the 2006 Volkswagen Beetle come with VW's innovative
    Direct ... It makes 100 hp and 177 lb-ft of torque and can get about 40 mpg.

    I have a 06 Colorado with 3000 miles. My torque converter disengages when I drive between 55 and 60 miles per hour. It’s been to the dealer ship 3 times. The result is the same normal operation. Is any one else having this problem?

    Chrysler is using a small diesel 4 cylinder in there small Jeep four door (can't think of the model name) and it is popular, but the engine is really garbage, and costs several thousand extra as an option. The engine they are using is said to be old technology, under powered, and very inefficient with fuel. It is rated at 22/26, but real world testing has net about 18 in one test that I was following. Jeep owners would have better luck with the standard 4 cylinder engine.

    Why would an Isuzu engine meeting your power figures be impossible? Isuzu is one of the biggest diesel engine producing companies in the world. They already have engines with figures such as what you have listed, or pretty close to it. They also helped design and produce the GM Duramax diesel engine.
  • I have found on the NHTSA website that there was a person with a rear main seal leak that occurred one year ago (1/21/2005). My problem occurred Jan 2006, that is one year later! :confuse:
    Is it too hard for GM to recognize a serious engine problem one year ago and fix it? Why did I have to go back to the dealer for 3 times and a total of 18 days to get this repaired? So as I have stated before Chevy gets to test there problems on my truck with no compensation to me. :cry:
    GM better wait up and listen to their customers, because if not they are going to be ex-customers. :sick:

    This is normal. It is between 45 and 60 depending on driving conditions that the torque convertor allows the transmission into overdrive, The only time you should really feel it, is if you are hanging around that speed range or if you are particularly trying to feel it. Relax and enjoy your truck.
  • mike2250mike2250 Posts: 29
    Is anyone else using a lot of brake fluid? I have an 05 Z71 crew cab I5 and auto trans. I use an 8 oz bottle every two months. If not I have a very inconsistent pedal. The dealer could find no leaks but replaced the master cylinder anyway. There has been no major improvement. Anyone else have a problem like this or some idea as to what to look for. thanks :confuse:

    You found 1 person at that site and you think the world has fallen apart. Come on, shall they stop building them until you are happy or what. Things happen and you just happen to be one of the unlucky ones. You think things are better on the Toyota forums? How about there hybrid Prius. In the northern states when the wheels start spinning when they get stuck, all shuts down and you are out of luck. You think they are happy? No, but they still praise their purchase. Everyone thinks the sun sets on foregn junk but they are no better or worse then US made and we would be a whole lot better off in this country if more people bought American. :shades:

    Neighbor just bought Colorado 2wd z-71 crew cab. Competent truck for his Home Depot runner. However, it has the world's worst tires. General Ameritrac. These tires beat you to death out on the road. Suggestions?
  • p100p100 Posts: 1,116
    Are you kidding me? I have not added that much to any of my vehicles in 10 years! You have a leak somewhere. Take care of it ASAP before something bad happens. I wonder if the fluid is not leaking inside you brake power booster somehow. But you said they replaced the master cylinder.

    One of the ABS system components could be leaking too.
  • p100p100 Posts: 1,116
    Yes, Buy a set of Michelin LTX M/S radials. Will last 70k miles without issues. If you go to dealer under warranty, you get a set of the same crappy Generals.(if they admit you have a problem with them in the first place).
  • p100p100 Posts: 1,116
    Jeep Liberty.
  • atlvibeatlvibe Posts: 109
    P100 is correct. GM will not do anything more than replace the BAD tires with more Generals. Why would they put such an awful product on a new truck is beyond me. Sad, you have to spend more money on a brand new truck to correct a problem that's not the owner's fault. Off to the tire store we go.

    Gearhead9, could you please send me the link to this NHTSA posting related to the mainseal leak? I have researched this on the website and was unable to find it. I paid a local oil change shop to do a service at Christmas time and they left the oil filter loose. Long story short, the filter spun far enough loose on the way home to blow out the majority of oil. The mess went all over the bottom of my truck and I keep finding oil on the garage floor. THis shop is tryig to tell me that I have a "main seal" leak, which was never the case before this mess occured. They claim that this is a well known fact but have not been able to find any valid information supporting their claim. For the record, I really love this truck and haven't had any real issues other than this "stupidity" stunt by this business. On the other hand my wifes Toyota has had 2 serious brake system issues in the 36K miles she has put on it. Also, similar in weight/power ratio to my truck and she rarely can attain better than 15 mpg. Appreciate anything you can provide so that I can get the facts together before presenting my case to their regional manager. Thanks, Mark

    Is it at all possible that you purchased "dirty gas"? Seems like so many here are just grinding that ax against the Evil Chevrolet. I have purchased gas from Clark that had so much water in it that I had to have the entire fuel system flushed. Seems entirely possible that the gas was contaminated from any of the sources from the refinery, to the truck that delivered it, the guy who replaced the pump at the gas station or even more likely... the dirty underground storage tank. Why are many of you willing to put your hard earned bucks out for something and then look for any reason you can find to tear the manufacturer of that vehicle apart? Seems like this is an American problem. If a Honda has it's door lock mechanism stop latching (real story), it's minor technicality and it's such a quality vehicle. A Chevy Cobalt has a tail light burn out... It's a G*d Da%n piece of American crap and Chevy ought to be sued for putting it on the road. No wonder our economy is so messed up. :mad:

    Has anyone put this new Skyjacker brand 4" lift on their Colorado and if so, what size wheels and tires will fit? :confuse:
  • vatakvatak Posts: 8
    I have a 2006 reg cab, 5 cyl, 4x4. Bought it about 3 months ago and it has about 3500 miles on it. Having had a very reliable S-10 for almost 10 years, I was hesitant to buy the new, unknown Chevy truck. But I really like this truck so far. It has a couple little irritations (the S-10 did too), but nothing significant or worth mentioning. I'm very satisfied and I think a lot of others with this truck are too.

    Anyway, I agree. Americans make good trucks, but foreign companies are still riding the coat tails of their former quality superiority.

    I have an 04 Colorado with the I5 I started having issues with the check engine light. However the light kept resetting itself and then it stayed on longer. I took it in and it took the dealership 1 1/2 hours to figure out the problem. They had to order the valve springs. I dropped the truck off on a monday morning by thursday afternoon they called to tell me they had bad news the valve springs did not fix the problem. they had to call technical assistance at GM to find out what to do next. They had my truck for another week and 1/2 before I was able to pick it up. Total of 15days out of service. The day after I pick up my truck I noticed a bucking in the vehicle. I have another appointment at the dealership on Saturday for them to figure out what they messed up when they replaced the valve springs and the head. I really like my truck but the more I read about the problems everyone is having I think I will opt for a different Chevy product the next time. It seems like I may have to go to the lemon law on this one. Currently the truck has 27k. :lemon: :mad:

    Did I buy dirty gas? I guess anything is possible. The stuff that came out of the filter did not look like gas dirt. I have been having engine shut-down issues since it had 3,000 miles. I took it back to the dealer many times and "they couldn't figure it out". I finally changed the fuel filter at 20,000 miles and the shut-down problem went away. I told the dealer of the solution and their reply was "couldn't be".

    This is my 14th GM vehicle. On the first 13, the vehicle was fixed when there were problems. This is not the first defect I have had with this vehicle. This in one of seven issues (three of them major). You tell me that I am complaining because it is American. I once owned a vehicle from one of those great German car builders and I'll never buy another car from them again! This Colorado is reminding me of that German car. I would rather buy American, but if it has issues, the car/truck builder should be expected to correct the problems.
  • temj12temj12 Posts: 450
    Don't accept that. That is too dangerous. What if the leak increases at some point in the future and you have brake failure. Make them give you a rental. GM will provide that. I had another problem and they provided one for me. Don't let that go!
  • motorhead1motorhead1 Posts: 111
    I sort of feel bad bragging about my 2004 ext cab 4x4 I5 but I have 27000 miles on it and no problems to speak of. I changed tires first thing so I didn`t have the tire problem. I love my truck because it does everything I ask it to do. I have had many chevy trucks in the past and I like this one the the best so far. I hope that all of the people that are having problems get through them and have a change to enjoy this truck, Good luck.
  • ocmike3ocmike3 Posts: 232
    My 2004 Canyon Crew 4WD I5 has been pretty much a champ for over 28k miles. My daily driver and although I changed the wheels and tires after a month or so of ownership, I never had any issues with them.
    I hope this forum isn't dominated by those with problems... I'm seeing quite a few Colorados/Canyons on the roads now and so far haven't seen any pulled over on the side of the road.
  • jpfjpf Posts: 496
    I feel the same way about the Colarado. I have a 2000 S10 with the 4.3 V6. I find this engine well matched to the size of the vehicle. I get 20 to 22 MPG on the highway and 16 to 18 MPG in city driving. For a totally new design, the 5 cylinder in the Colarado does not seem like much of an improvement given the huge drop in torque when compared to the S10's V6. I hope GM makes some improvements to the Colarado by the time I look for a new vehicle.
  • mike2250mike2250 Posts: 29
    Unless you are pulling tree stumps or doing some wild four wheeling, why do you need the amount of torque as the 4.6 liter in the S-10. Sure it's nice but off the line the S-10 bogs down due to the torque and the way the transmission is geared to use it. I have had experience with the S-10 and to tell you the truth; in my opinion I like the acceleration of my Colorado Z71 crew cab and I have plenty of torque for normal conditions. Don't forget the horsepower of the 3.5 is not that far off the 4.6. Just my two cents worth, but I'll stick with my I5. :)
  • motorhead1motorhead1 Posts: 111
    I have to say that my I5 is not as strong as my Corvette but it really suprises me when I pull out to pass a car. I installed a K&N filter and it seems to help at full throttle and it also helped my fuel milage 1 mpg. Someone was saying earler that the interior was cheep looking well I agree it`s not what you would expect on a truck that list for 23k-29k but I guess it grows on you. Unless something bad happends I will keep this truck for a long time and the next one will probility be another Colorado. Maybe GM will do a little better job on the little things on the newer trucks.

    So far so good with the 5cyl ,I traded in a ford reg cab stepside with a 5.4 ,it was a rocket getting 14-19mpg,and 50 more hp but theres more than enough with the I-5 220hp plus being a crew cab LS,about the same options as a XLT.And im getting ready for the higher fuel costs in the future. This is my forth PU [chevy or ford] in the last 35 years],and so far its a keeper.The dealer :( in Concord, calif. is another story, but his competion down the street is good. Thanks for the information and Good luck. JB. :)
  • atlvibeatlvibe Posts: 109
    The I -5 is a decent engine. It stops there. Competitors have engines with more punch. That's the shame of it. If the truck had the punch of the Taco or Nismo you would see more on the road. Again, I'm not saying it's bad, I am saying it's a crime it's not better. Otherwise, Colorado is an attractive package in the Crew cab z-71.
  • jlb2jlb2 Posts: 18
    If more power is what your after there might be a problem,with the others [Taco,Nismo]your pulling more weight etc, so why not just go with a halfton.Thats a choice not a crime. JB. :)
