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 2004 GMC Canyon doesn't show any major complaint trends, it's mechanically-identical counterpart is the Chevy Colorado which has some engine problems.

2004 GMC Canyon Owner Comments

problem #1

Sep 172011

Canyon SLE 2.8L

  • Automatic transmission
  • 176,000 miles


Well, basically what happen is, when the motor is warm and you going to stop, about 10 to 15 mi/h surge and feels like is going shut off . And when you stop quit, idle normal. Know, let say you stop and shut off the motor, when you cranked again, surge between 5 to 10 seconds and then idle normal.

What I notes is NO VACUUM on the small hose connected to the fuel press regulator. According with the book,(Haynes Repair Manual) should have between 12 and 14 in-Hg of vacuum. I just replace fuel filter,the air filter is clean, and we use 87 octane gas, don't have no codes at all. Whoever can help appreciate, THANKS
