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: The GMC Canyon is mechanically identical to the Chevy Colorado.

2009 GMC Canyon Owner Comments

problem #1

Apr 122010

Canyon 4WD

  • 12,000 miles


Was driving slowly in a parking lot and was starting the turn into a parking stall when the steering became very difficult and the vehicle had difficulty moving forward. Transmission had gone into 4X4 low without anyone pushing the button on the dash. I had a 2007 Canyon and it did the same thing about 3 times while driving in a parkade. When I contacted the dealer there comment was to bring it in while the incident is occurring. When I did take the 2007 in for service they could not find anything. I will mention the incident on 2009 when it goes in for its next service.
