The power steering on my 2015 GMC Canyon has failed repeatedly while driving in different road conditions. In one case, I was going straight on a surface street at low speed. However, in another I was cornering through a highway off-ramp at approximately 45 mph. When the power steering fails, there is a warning chime and the power steering and stability control warning lights activate simultaneously. It becomes extremely challenging to steer, and in the case of cornering at speed the vehicle pulls in the opposite direction of the turn [ie, it pulls towards danger]. pulling over and restarting the vehicle has 'solved' the problem each time, albeit temporarily. I took the vehicle to a GM dealer to get fixed, but they could not find any related mechanical issues or GM provided sw patches that would fix the problem. So the GM dealer had me leave without fixing any of the underlying conditions that caused the power steering failure. Needless to say, this is an extremely dangerous and apparently wide-spread issue based on the number of similar complaints I have read.

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.
