#280 of 386 Re: tire wear on colorado [shareholder] by leadfoot4 Oct 24, 2008 (2:53 pm)
Replying to: shareholder (Oct 24, 2008 11:18 am) 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..... Replies to this message: toofast1 (Jan 21, 2009 10:21 pm)

Replying to: Mr_Shiftright (Oct 24, 2008 1:21 pm) 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..... Replies to this message: Mr_Shiftright (Nov 14, 2008 10:42 am)

Replying to: donnyr (Jun 08, 2008 10:04 am) 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??

Replying to: leadfoot4 (Oct 24, 2008 3:05 pm) 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.
#284 of 386 '08 Colorado acts like in neutral by exnavysnipe Nov 20, 2008 (10:22 am)
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.

Replying to: jeepfan6 (Nov 23, 2008 7:05 pm) 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.

Replying to: tobolob (Nov 14, 2008 10:20 am) 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.

Replying to: slumpcone2001 (Dec 13, 2008 10:06 am) It'll stop pretty soon as there won't be any left.
