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.

problem #2

Canyon 5-cyl

Reduced power light came on the dashboard and I had no power. This has happened 4 times since July 2013. It has happened 2 times in April and now again. It is going back to the garage on tues. Getting ridiculous and expensive! when it is put on the scope it keeps coming up with the throttle position sensor fault.

Canyon 5-cyl

  • 52,000 miles
I pulled into the parking area of a grocery store and stopped in the driving lane of the lot. Upon backing into a parking spot, the shift lever moved freely in my hand and would not shift gears. I rolled forward into a parking spot and called aaa assistance. Upon aaa's arrival the technician crawled under to truck and reattached the transmission cable. Over the course of several weeks the cable came off the transmission linkage several more times. I made an appointment with the dealer to have the linkage replaced. The end of the cable was made of plastic and appeared corroded.
