Service brake assist light comes on and Vehicle loses braking power. Brake pedal gets hard and unable to stop if needed and has potential of injury / accidental death. This similar problem has been recalled in the larger trucks /SUVs due to safety issues. It appears it's also happening in the smaller truck's canyon and Colorado's as well, however no recalls. Many blogs online discussing the issues and failures of the braking system.

Lost power steering, power steering service message, ABS light, traction control light, and "!" light all came on. Matches up to recall information available. Took it to Chevy, it's not covered, costing $400. This should have been covered in the power steering recall

Low speed braking becomes difficult as resistance in the pedal makes it difficult to stop the vehicle when in motion at lower speeds. The vehicle also leaks fluid. Dealership informs me the vacuum pump has a leak which may be causing this issue and the leak. Vehicle has been leaking fluid, an oil or oil like substance for about 10 months.

I was parked. When I started the truck I put it in reverse. While backing up I applied the brakes. The power for the brakes was gone. I had to slam as hard as I could to stop the truck. A very scary situation. I heard there was a recall for this problem. I went to this website to find out. It states there are no recalls on this truck. This is a very dangerous problem. If GMC puts a product out like this they should fix the problem. I took it to the dealer all he said to me was it dangerous and it would cost this much to check it out. Nothing about it was a recall or not. Please let me know if this is on them as I still have to drive the truck.

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.

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.
