Chevy Colorado and GMC Canyon Engine Problems



  • gfcargfcar Posts: 2
    I have the 08 Chevy Colorado w/the 2.9L engine. Experiencing the same problems with engine knock during a cold start. Service managers and GM customer serv reps are all giving me the run around. What type of engine do you have in your new Canyon? I am also experiencing severe leaks inside the cab. Testing w/a hose on my own, I can tell the water is coming in from the back somewhere. GM and the service manager at Chevy tried to tell me the water was entering the car through a vent. Actually told me I have to keep my vent on recirculate when there is wet weather. What a joke! With all these issues occuring within the 1st year of ownership, GM wants to tear the truck apart, but not give me a new truck. Did you pursue the Lemon Law at all while dealing w/all of your issues? If anyone is having similiar issues, please let me know and contact GM or your service department, because it is definitely an issue.

    Can you get a 5 speed with the 3.7 engine. Ken

    If you mean a manual transmission 5 speed, I believe the answer is no. I went through all that a year ago when I was trying to get a manual transmission, and they have apparently become like photographic cameras - almost totally replaced with digitals, or in this case - automatic transmissions. Everyone tells me that no one orders those, so the factories have stopped making many of them. Well, you can get one, but only with the smaller engine, and I believe with not as many of the option packages. I ended up having to settle for the one they had in the showroom, which happened to be a 3.7 with an automatic. It had most of the options I wanted, and not many I didn't, so I settled. Shouldn't have to do that with the largest automaker, but this seems to be a society where customer service in all regards is not the priority anymore.

    I retired from GM and worked at the Lansing Car Assembly which built at that time the Grand Am, Buick, and Olds versions. We ran 2 assembly lines with each line running 60 cars an hour on two shifts of at least 8 hours each. That is over 1900 cars per day. We would build about 2 cars per hour per line with manual trannies. Thats around 64 manuals out of 1900+ cars per day. We lost money on everyone of them due to the so few we built but had to keep them in the mix to conpete with the Toyota's and Honda's which those type of people tend to buy cheap models though most americans that buy domestic perfer automatics. Hope this helps you understand why GM don't make a manual in the 3.7. Those that buy the 4 banger buy it for only one thing, either they want the cheaper truck or want the most mpg's they can get.

    "gfcar", regarding your water problems...There IS a ventilation system vent at both of the lower sides of the cab. They're visible between the cab and pick up box. Make sure that A) they're both in place; and B) the flaps are "closed" and/or not damaged.

    You have the same problem? or something else
  • I have this problem, I have a 2005 Colorado, front tires wear preferentially on the inside the dealer has aligned it 4 times, (3 times at my expense of $100) each time saying it will solve the problem, and it has no impact. I'm on my third set of front tires in 42k miles, first set replaced under warranty. This truck replaced a Ford Ranger that I drove 150K without ever getting an alignement, never rotated the tires and never had an issue.

    GM agreed with the dealer that the alignment should solve the problem, and that its my fault becasue I didn't rotate the second tires every 6K miles. They really haven't agreed to do anything about this, it seems its normal. I have been rotating at 6K, but there is no way this won't kill the tires early they are bald on the inside in 20K miles. I will have to take it back again, but I'm not anxious to waste another $100. Anyone had this problem successfully fixed?

    Bulletin No.: 04-03-07-004B

    Date: July 22, 2005

    Premature Front Tire Wear (Set Front Z Height, Toe and Rotate or Replace Front Tires)

    2004-2005 Chevrolet Colorado
    2004-2005 GMC Canyon

    Built Prior to November 18, 2004


    This bulletin is being revised to add a build date to the Models. Please discard Corporate Bulletin Number 04-03-07-004A (Section 03 - Suspension).


    Some customers may comment on excessive front tire wear on the inside edge of the tire.


    On four wheel drive (4WD) models, an incorrect Z height trim setting, resulting in an excessive front sum toe-out of specification, may be the cause.

    On two wheel drive (2WD) models, an incorrect front sum toe setting may be the cause.


    Follow the procedure below for diagnosis and repair of this condition.
    Important: Prior to performing any tire repairs, permanently record the current tire inflation on the repair order.

    1. Permanently record the tire pressure settings on the repair order.

    2. Inspect the inside edge of the front tires for excessive wear.

    ^ If the inner front edge of the tires are worn to the wear indicators, replace the front tires and continue with the next step.

    - For repair information, refer to Tire Mounting and Dismounting.

    - For tire warranty information in the U.S., refer to Warranty Administration - GM New Vehicle Tire Warranty Program Bulletin Number 00-03-10-003I, dated June 2005.

    - For tire warranty information in Canada, refer to Warranty Administration - GM of Canada New Vehicle Limited Warranty Tire Program Bulletin Number 01-03-10-003B, dated April 2004.

    ^ If the inner front edge of the tires are not worn to the wear indicators, rotate the tires and continue with the next step.

    Important: Prior to performing any additional repairs, permanently record the following information on the repair order.

    ^ Z Height

    ^ Alignment Measurements

    ^ Fuel Level

    3. Set the inflation per the vehicle tire placard located on the driver's door.

    Important: On 2WD models, DO NOT replace the front coil spring(s) or add insulators to compensate for a low trim Z height. A lower trim Z height reading is acceptable as long as it is within specification. Refer to Trim Height Inspection Procedure.

    4. Check and adjust the vehicle Z height.

    Important: ON 2WD models, ONLY replace the front coil spring(s) if the trim Z height is too low and out of specification.

    5. ON 2WD models, ONLY replace the front coil spring(s) if the trim Z height is too low and out of specification.

    6. Check and adjust the vehicle front toe to 0.00°+/- 0.20°.

    7. Road test the vehicle in order to verify that the steering wheel is straight.

    Shareholder, there is no way you should be wearing out the inside of the tires that quickly. My opinion is that the dealer, even though they are "aligning" your truck, they're not working within the limits of the specs to eliminate your problem.

    Many of the newer alignment machines have the "red" (out of spec) and "green" (within spec) scales built into their software, and many of the younger techs simply get the machine's screen "in the green", and proclaim that you're "good". They don't yet have the understanding or experience to diagnose problems accurately, and formulate a "custom" solution to your problem. Also, I'm sure that GM exerts a certain amount of leverage on them to adjust "to the green settings" regardless of what the tire wear is saying.

    Well, "good" is still wearing out your tires, so you need an "old fashioned" wheel alignment man that will read the problem, and tweak the specs a bit, to fix the situation. It would appear to me that if you're wearing the insides of the tires, you have either A) too much negative camber; B) too much toe-out; or C) a little of both. Maybe, in order to fix your particular wear problem, your truck needs to be a little in the "red" zone, and you need a front end man that know suspensions, and not just how to turn the adjustment bolts to get it in the "green".

    To be honest with you, I DO rotate my tires, but I sincerely believe it isn't the cure for everything. Look at how many cars today have staggered tire sizes, directional tread patterns, or both. Can't rotate the tires on a car like that.....

    Shiftright, that's avery interesting post, howver it lacks one important thing...The ride (trim) height measurement!

    When I first took delivery of my Canyon, I picked it up in the evening, and it was snowing pretty heavily. Therefore, I basically drove straight home, about 2-2.5 miles, and didn't realy get a feel how it handled. The next day, while driving to work, I was shocked! The truck was all over the road.

    I have a general distrust of dealers, so I took it to my trusted front end man a couple of days later, to have the alignment checked, as I felt it HAD to be off....way off! Long story short, the alignment was OK, we bumped the air pressure 5-6 lbs. and the truck was somewhat drivable.

    A few days later, I put 4 Blizzaks on the truk, as it was primarily my winter vehicle, and it was like a different truck altogether. The OE General tires were SO BAD, that a good set of snow tires made it handle 100% better!

    Anyway, do you happen to know the trim height spec? Just out of curiousity, I'd like to check mine. (It's a 4WD, Z-71) Thanks!

    As a side note, I mentioned this in another Canyon/Colorado discussion...I switched to 16" rims and 245/75/16 tires, as well as adding a rear sway bay. It handles quite well now, for a 4x4, that is.....
  • I bought a 08 Canyon in April and I have idle engine problems that the dealer can't seem to fix. The truck when stoped acts like its going to die and shakes. There are no lights to indicate that there is a problem but its not normal. The dealer has tried re-programing the computer two different times and said they cleaned out the trottle?? GM said that they have the latest computer program that they will have to try but ill have to wait and see. I also have had other problems such as: windsheild wipers going off whenever, seatbelt issues, and backfiring. Any info that could help my cause??

    No I don't know where I'd find that measurement. Your alignment guy should be able to find it though in his spec sheets.


  • I have a 08 colorado 5cyl 4x4. the engine seems to not shift from low to drive. the engine is very loud and truck will only creep. At times it seems to drop to neutral. All this happens at start up before the engine warms up. It will be fine the rest of the day. I had it in to the dealer twrice, but they say it is normal or that the computer says it is ok. :confuse:
  • Hi!
    Have you tried with Mobile 1 5-30W fully synthetic oil. My noise disapeared!
  • poncho167poncho167 Posts: 1,178
    Not saying this is the issue, but the torque converter has a lot to do with your shifting and ability to get up to speed.
  • I have had the same problem. When I would come to a light my rmps would drop to about 400 and shake. It had 36700 miles out of warranty. They said it was still within the specs and since out of warranty they could noth. $300 they clean throttle and fuel rail and reset computer. 15,000 miles later it began to stall at light about once a week. I refused to take it in, but when it stalled turning left in traffic I had no choice. I told GM Service that I would not pay 300 dollars every 15,000 miles. This time only 89 dollars. They claim that they could not find anything wrong with it because no check engine light on. I also noticed when it was having these problems if you put it into neutral when getting on the highway the rmps would bounce between 400 and 1200.
  • Now my 2007 Colorado 2wd 3.7L 81,000 Miles is loosing some coolant. About a half of gallon

    I am going to wait and see if it continues. Before I take it to the dealer.
