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 2015 GMC Canyon has a significant trend of transmission problems.

Most owners reporting transmission problems with their 2015 Canyon report sluggish shifting or other similar problems with the truck not shifting properly. Although most of these 2015 Canyon trucks are still under warranty, it's not a good sign.

The GMC Canyon is mechanically identical to the Chevy Colorado.

2015 GMC Canyon Owner Comments

problem #5

Jan 012016


  • 12,000 miles


Rear brake squeak and long stopping distance. Anti-locking function does not engage and the braking system does not skid/lock up the tires in an emergency stop. Rear pads do not match size of the rear discs. Rusty dust build up. GM has attempted to fix 3X and indicates that there is no fix for the issue. Squeaking on every stop will not allow driver to discern if the pads are worn or not.

Brakes squeak on every stop. Will not be able to determine when the pads need changed since the squeak is same as the pad worn indicators. Also vehicle will not stop with antilock brakes or skid the tires. It stops, but is mushy.

The contact owns a 2015 GMC Canyon. While driving approximately 60 to 65 mph on a four lane divided highway with the cruise control activated, the power steering failed. The vehicle was pulled over to the shoulder, turned off, and restarted. The power steering pinion, gear, and electronic brake control module were all replaced. The vehicle was repaired. The approximate failure mileage was 7,458.

Canyon 4WD 6-cyl

  • 69 miles
Almost immediately after initial start of vehicle, shifted from park to reverse and while backing out of garage, a message appeared in the driver information center (dic) that read: "service, brake assist, dismiss" - a few minutes later received two emails from onstar which read: An issue with the antilock braking system in your 2015 GMC Canyon crew cab has been detected. An issue with the stabilitrak® stability control system in your 2015 GMC Canyon crew cab has been detected. Subsequently, visited selling dealership and they checked fuse in relation to tsb # pb-14669, NHTSA id # 10056603. Dealership found 30 amp fuse to already be in place. Cleared trouble code, but it has since displayed several times in the dic. Continue to receive several emails from onstar with subject line of "onstar vehicle health alert notification for your 2015 GMC Canyon crew cab" - onstar has advised that these are "false email alerts" and that General Motors is working on a fix for this problem, but no update or fix is available at this time. No estimated date of resolution, and unknown exactly how serious this apparent safety issue might be.
