Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: While the 2005 GMC Canyon doesn't show any major complaint trends, it's mechanically-identical counterpart is the Chevy Colorado which has some engine problems.

2005 GMC Canyon Owner Comments

problem #4

Canyon 4-cyl

  • 24,090 miles


Recently purchased used 2005 GMC Canyon, two days after purchase check engine light came on and stayed, the truck did not run rough or make noises. Took directly back to dealership, it was determined the oxygen sensor was bad. Replaced. Five days later the same thing happened...diagnostics determined catalytic converter, oxygen sensor and exhaust intake were all related. All repairs now complete and appear to be no other issues after driving the vehicle 3 days.

: the contact stated while driving 50 mph on a highway on-ramp, the vehicle stalled completely. The vehicle was able to be restarted after 20 minutes. A service dealer was contacted, who stated that the vehicle would have had to have been brought in before it was restarted in order to diagnose the problem. Subsequently, the vehicle was not taken in for service. Updated 12/5/2006 -

Earlier I complained that I had to replace the cam shaft solenoid for the second time, I was mistaken in that complaint, now I am told that it could be an actuator, cam shaft problem or some other related problem. Getting the same error codes as last 2 times in the shop P014 P017 and P300. Engine is till sputtering and dying, pushing too much fuel.
