Recently, my Fuel Cap warning light displayed, went off after a restart and then came on again a week later. After shut down and restarting 2 hours later, the engine light came on. The engine light went off for awhile but has since come on again. The Fuel Cap light goes on and off irregularly. Is this an electrical problem or actual problem (I did read code P0455: EVAP System Leak)? A GM mechanic advised that it's $600 for the test to determine what parts need replacing! Apparently, there are a number of parts that, if defective, will trigger code P0455.
The no-start Gremlin also showed up again on 10/15/10 after an extended absence. I’ve had inadvertent no-start symptoms for over 2+ years but the problem has never been determined or discovered by the dealer (they had the truck for over a week once). Of course, GM will not cover this issue because I can not provide proof the problem was first addressed within factory warranty.
There are numerous posts on Edmunds forum about the no-start Gremlin, Jhacket (reply 505) and crashrecovery (507) most recently. Why won’t GM acknowledge this problem? Can anyone provide more information about codes B2960 or B1383 mentioned by crashrecovery? Are these codes the actual problem and how much will it cost to fix? Does anyone know if GM will cover this problem as a known defect?
My ABS Fault warning light has also displayed on and off since 8/2008 approximately 1 month after the dealer did a brake job. They claimed it had nothing to do with their work but they were happy to advise that the right front hub wheel bearing assembly and sensor needed replacement ($800+). I replaced the parts for less, albeit not at the dealer, yet the warning light still came on and the ABS braking still didn’t work. I tried replacing the sensor again and now the ABS braking kicks in inadvertently on dry pavement, then the light comes on and the ABS stops functioning. What gives?
Clearly, these trucks have major defects, many of them electrical. This truck is bleeding me, as I’ve easily invested close to $2G in repairs beyond the factory warranty, and that doesn’t cover the GM costs within warranty.
Since 05, I’ve had problems with:
4W self engagement
Tie rods (replacement within 20K)
Transfer case control module & leakage
Front axle seal leakage
Emergency flasher module self activation
Various squeaks
Trailer hitch harness inoperable
Defective front seat cover
Throttle body, actuator
Injector feed wire breakage
Brake lamp switch
Radio display
Radio Bezel
Cylinder head and intake valve replacement
Cracked manifold
ABS braking system default
EVAP system default
Is this normal or does anyone know if I might qualify for the Fed lemon law. I was a previous S-10 owner and only experienced typical maintenance, wear and tear problems.
Seeking inexpensive help or suggestions. Any answers are appreciated. Thanks.
Government Motors ploy to discredit Toyota in order to keep
General Motors employee retirement funds financed.
Apple Pie & Chevrolet no longer relate. If Toyota is out of the question - Transfer to Ford. No government ownership involved there.
I will keep all informed on the status.
I apologize for your experience. If you would like to e-mail me your VIN I would be happy to look into recall information for you.

I bought a used 2005 Colorado Z-71 I-5 in July 2009 with 29,000 miles. It came with the CUV warranty 12/12k miles. I noticed a rough idle earlier this year and asked the dealer to diagnose while it was in for an unrelated service. They offered me a fuel injector cleaning service which I declined in lieu of some fuel injector cleaner. I’m out of warranty at this point, and the truck runs terrible. The idle fluctuates erratically to the point that the lights dim a stop lights and check engine light is on almost constantly.
What should I do?
If that doesn't do it...change the fuel filter...then maybe O2 sensor...but hopefully the MAFS and TB cleaning do the trick
Also anyone have issues with oil changes taking a long time to even be seen on the dipstick? I can run my truck for 10 minutes and it won't show full after an oil change.
Yes, it takes a while for all new added oil to drain down to fill the pan in the 3.7 litre. I would not put any additives in. It is the oil that counts, so buy the best you can. On an oil change, you know how much you added for the total amount, so no concern. I also add to the filter before installing it up, so the pump is primed.
I use synthetic in small engines, lawn tractor, etc. too. Thanks!
I have no ideas about what is causing this.
Thanks!
If he tested it properly for you by getting under the car and applying a meter to the sensor, then okay.
Thanks again!
Can you please email me your complete contact info including a good number to reach you, VIN, current mileage, involved dealer, and your Edmunds username (or a link to this page). I look forward to your response.

I had engine ticking on my 05 Colorado, as well as many of the other problems you mention. Head and valves were replaced under GM special warranty. Dealer advised me that the ticking noise was caused by a cracked manifold, which GM would not cover under the special warranty. The ticking is gone, but I poured $500+ more into my black hole.
As far as buying American and accepting that all vehicles have some problems...JD Powers ranked the Colorado (#2) and Canyon (#?) among the top 7 worst vehicles made in 2010 so it's reasonable to assume there's more than a handful of Colorado problems. My mileage is still under 100K, and the defects I've experienced are unacceptable and too long to list. At least other unsuspecting GM loyalists won't have to worry about buying a Colorado, as I heard GM is bailing on this truck. Apparently, I've been a loyal GM customer for too long and it's time to consider bailing on blind loyalty.
Good luck.
Happy New Year everyone!
Dealer says ther are no notices on this and the software is the latest version.
Anyone else have experience with this issue?

Has your dealer involved Technical Assistance? Have you spoke with Customer Assistance? I look forward to your response.

I was talking to a mechanic and he was telling me that this is not an uncommon problem that is starting to come up with the rack and pinion in the trucks. He was also telling me that GMC was trying to keep the problem on the down low. Now is it true I cannot say if he was right or not. The gmc dealer was unaware of the problem.
I would like to look further into your situation. Could you please email me your VIN and the involved dealership?
Thank you,

I also experience a no-start phantom phenomenon which appears now and then. I'm currently experiencing this problem as well but I've taken the truck to the dealer 3 times over the last 2 years and they've never found the real source of the problem. However, they replaced the head under the GM special extended warranty. Guess what, it didn't fix the problem.
The truck has obvious electrical problems. Maybe GM or the Fed can help you. Don't expect much from the dealer. Good luck.
