Also once while running in my driveway for about 3 minutes power steering shut off and stability system warning came on truck was still running had to shut truck off and restart.

On two occasions recently, my power steering stopped working, once on start up and once while driving. When this happens, I get warnings that other systems aren't working, such as stabilitrak and backup assist. Problem seems to correct itself, after turning the truck off. This happened Sunday, June 16th while driving and back in March when I first started the truck.

I was driving on the downward slope of the steep Mississippi bridge in baton rouge, la and loss my power steering control. Luckily, I was able to pull to the side of the interstate. I complained about this a month ago when I took the truck to gerry lane GMC. I was told it was a bad battery. So I purchased a battery from the dealership. Not even a week later the same problem occurred. However, when I cut the ignition off and crank back up it resets. The service advisor stated to bring it back in if it happens again. This time (about two weeks later) while I lost power I was able to video so I can show this advisor what keeps happening. This time it took me at least 4 times cranking up and then shutting off the engine to get it to reset so I could get back home and switch cars. I was too afraid to continue driving going over the next bridge that's 20 plus miles without an exit and lose power steering again. I've had to rent cars for this repetitive occurrence with this truck that seems to not be able to be repaired. Or either they know what's wrong but waiting for it to be out of warranty for me to take on the cost of repairing it. But this is not safe to keep loosing power steering and I'm driving anywhere between 50 to 70 mph. I also explained that when I park I can't turn the key to take out of the ignition. So again I have to crank up and pull forward to try and reset so I can be able to remove the key from the ignition. I took a video of that as well that I can't post.

After turning the vehicle on I got the following messages showing in the display panel 'engine power is reduced' and 'stabilitrack' also the following lights turn on 'check engine' and 'tc' off. Then I can heard a weird noise coming from the engine. When I moved the car from one place to another, the car lost power.

I was taking a corner to go up to my road and then my power steering chime went off posting power steering has failed, then a message saying the stability control isn't functional. I drove into a small ditch because I couldn't turn my wheel. I was at a slow speed. I turned off the truck, and the warning went away. This has happened at least 8 times and have taken it to two dealers and the final dealer said I couldn't drive the truck until I replace the rack & pinion assy. He has said this should be part of the recall. My truck was built Dec 05, 2014 and inspected on Jan 01, 2015. This just costed me $1700.

While driving the power steering fails. The election control check light comes on during this time. This starts when driving and only resets itself once the vehicle is turned off and back on several times.

On separate occasions while vehicle was in on position (in drive, in motion, and/or in park), alerts came on dashboard alerting to 2 service issues. 1. service stabilitrak and 2. service power steering.

Upon restart, vehicle dash alerts and power steering issue were no longer apparent.

Less than 48 hours after a dealer oil change, my 2015 GMC Canyon experienced a power steering failure while making a right turn at a light. Stabilitrac/traction control failure also occurred with service notices and fault lights appearing on the dash. Vehicle had to be towed via flatbed to the dealership.

- Melbourne, FL, USA

Vehicle was stopped at a stoplight when the instrument cluster started alerting that stabilitrack stability control needed to be serviced and power steering was disabled, as well as the traction control off light was illuminated in the instrument cluster. Turned vehicle off and restarted - power steering message reappeared but quickly went away and power steering function returned. The next day while driving < 30 mph on city streets the error messages and problems reappeared 4 or 5 times.

Twice while driving the power steering has gone out and the stability control light has come on. The first time I cut the truck off and restarted it. At that point it appeared to be fine. Now it been about 2 weeks since the first occurrence and this morning it happened again. I researched to see if there were any recalls. There is a recall on the power steering for the 2015 Canyon but I'm being told that my truck is not on the list. I think they need to look deeper into this problem.

Power steering and stability control drop out while driving at any speed. Turning the vehicle off and cranking again will restore power steering. Sometimes this must be done 2 or 3 times to get power steering back. This is happening daily.

- Pelham, AL, USA

I was driving about 35 miles an hour when stabilitrac and loss of steering assist warning lights came on. Steering became extremely difficult and I veered into the oncoming lane while making a right hand turn to exit the main road. I was going to have the vehicle towed to the dealership, but the dealership service agent recommended turning the vehicle off and restart after 30 seconds. This worked, but I took it in to the dealer to have it checked. They found no fault codes. Five days later it happened again while on the interstate doing 70 mph. Fortunately, I only needed to make three turns to get to the dealership. The dealership replaced the power steering rack assembly at a cost of $1662.01. I contacted GM to ask if the expense would be covered by recall 16V054000. I was assigned a case serial and after several inquiries, a senior GM representative stated it was not covered by the recall and it was a different module causing the recall. She offered a $100 voucher for future vehicle service and closed my case as dissatisfied. Regardless of the module, loss of steering is a life threatening hazard and the recall should be expanded. The vehicle had approximately 81,900 and 82,100 miles when this occurred.

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.

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.
