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

Dec 082005

Canyon 5-cyl

  • Automatic transmission
  • 41,051 miles


Rear turn signal lights, brake lamps and head lamps experience permanent loss. Sometimes when the vehicle becomes wet the cruise control stops functioning, the power door locks stop working, the power windows stop working, and the power rear view mirrors stop working. Also there is periodic non-functioning of the remote key entry. As of 11/10/2006 the rear tail lights have been replaced twice and one head lamp at owners expense. Currently a third brake light requires replacement. On Nov. 10, 2006 I took the truck in for repair an mentioned the recall on this particular problem. The dealership said that GM has not issued a recall and that the owner would have to pay for the repairs. I am aware of the "NHTSA campaign number 06V-139" and GM's April 26, 2006 response to Mr. Daniel C. smith, associate administrator for enforcement, NHTSA. Although the recall references only the brake lamps and possibility of cruise control failure, I believe the problem is further exasperated with the other afore mentioned electrical problems. Consequences present themselves in the form of distractions to the driver when trying to drive and make adjustments to the following electrical componets when they fail to function: Door mounted rear view mirrors, lowering of windows in order to pay for highway tolls, rear brake lights and turn signal lights fail, and reduced head lamp failures.
