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.

Concerns regarding no key lock on the passenger side of the 2004 GMC Canyon. This vehicle has manual door locks, an a key lock is no longer provided on the right door. Consumer states this could be a problem in the event that emergency access were required.

I recently purchased a basic 2004 GMC Canyon (I.e., no power windows/locks). I was not informed that the passenger door did not have a keyed entry. I recently saw another complaint regarding the same issue on the NHTSA website and have seen other comments on other websites. Additionally, a friend also bought a basic 2004 Colorado and was not informed of the lack of this feature. Aside from the nuisance in not being able to open the door directly, I agree with the other complaint on the NHTSA website that this is a potential safety issue if the driver's side door is blocked and a child or other person becomes injured or sick and you cannot open the passenger side door. Personally, I believe that GMC should offer to correct this problem on these basic trucks or at least offer the modification at a reasonable price. I E-mailed GMC regarding this issue but the response basically skirted the issue. I also included the above comments to GMC on the customer satisfaction form.
