Ignition locking solenoid fails to release when put into park, resulting in the key stuck in the ignition. I'm then unable to leave the vehicle unattended without threat of theft or battery failure. Dealer has not been able to fix the issue. No warnings or failure indications are observed, other than the key being stuck.

- Charlotte, NC, USA

the system failure is the power steering control module rack and components The safety risk is loss of power steering assist, no traction control, StabiliTrak message on dash, abs and traction control lights is on, don't feel safe to drive. The problem is confirmed by a dealer. The component has not been inspected. Yes, there are warning messages on the dash, and they appear in February 2022. A loss or reduction in power steering assist may increase the risk of a crash. In my opinion, this issue has to be solved and fixed by the dealer at no cost to the customer.

While driving the vehicle, the power steering suddenly went out. My teenage son was driving and luckily he's had training on this in Driver's Ed or it could have caused a major accident. It has since happened to me while on the freeway and while going up our driveway. I took it into the dealership where I purchased it and they could find nothing wrong, but clearly something is wrong with the wire harness or power steering. I suspect the parts used were part of an earlier recall on GMC Canyon's as the recall ended with vehicles only a month older than mine.

- Cherry Hills Village, CO, USA

The contact owns a 2015 GMC Canyon. The contact stated while the vehicle was stationary, the service 4WD warning light illuminated. The vehicle was not taken to a local dealer nor independent mechanic to be diagnosed. The vehicle was not repaired. The manufacturer was informed of the failure however, no additional assistance was provided. The failure mileage was approximately 44,430.

Power steering assist shuts off while driving on normal.

Service 4WD message again appears. When driving and switching into 4WD received this message. Third time, needs "reprogramming". filed complaint with GM about a design flaw and no satisfaction.

Hi. this is my second formal complaint regarding intermittent loss of power steering, traction control, and stability control on my 2015 GMC Canyon. There have been recurring temporary losses of the aforementioned vehicle capabilities while the vehicle is in motion, leading to severely degraded vehicle performance, handling, and traction. In every case, warnings lights have displayed immediately before the loss of control. These lights have also 'turned-off' or reset when the vehicle was restarted. I have repeatedly brought my truck into authorized GMC service appointments soon after the warning lights and performance failures, or in one instance as the warning light was actively illuminated. Each time, the service department was not able to recreate the issue or pull any relevant service codes related to the problem. Needless to say, I do not believe the root cause issue has been adjudicated and I think this represents a clear and present danger to drivers of the 2015 GMC Canyon such as myself. While my truck was not part of the past recall, this seems strongly related to the prior steering gear connector recall.

I was taking off from a stop sign and turning right into traffic. Acceleration was moderate while completing the turn where I had to reduce the throttle to prevent the tires from spinning. The transmission shifted into too high of a gear as a result and did not downshift when 50% plus throttle position was applied. Engine had lack of power. I had to stomp it to the floor to get it to downshift. By this time traffic was coming up on me fast because of the excessive delay trying to get the transmission to respond. The truck has the most current software updates based on what the dealership told me.

Vehicle stalls then jerks forward when accelerating and decelerating. Jerking causes brief loss of control as vehicle lurches forward while transmission attempts to catch up. This occurs at any moment while driving (uphill, downhill, turning, city streets and highways) seems to occur most when speeds are under 60 mph. Causes very unsafe conditions and check engine light goes on and off. Occurred today and has occurred almost everyday since I've owned the vehicle. (2 years)

- Maumelle, AR, USA

Vehicle has a bad shudder where it is causing drivability issues. This occurs mainly when driving up an incline when at about 1200 RPM. Truck will sometimes jerk and shake and has poor throttle response causing dangerous driving conditions. This has happened several times over the coarse of about 3 months with the last instance occurring today.

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.

While driving with vehicle in four wheel auto the transfer case engaged in to 4 wheel high and would not disengage. This would be more of great safety concern in the event that a driver is not able to pull over and stop. The vehicle would not disengage the four wheel drive and required to be towed to dealership. The work performed to correct this issue indicated there was an excessive amount of corrosion in the the connectors related to the "range selector" and other related components. This appeared to fix the issue, however the issue has resurfaced over time and again seems related to corrosion. In more recent occurrences the vehicle engaged into four wheel drive while driving and it was not set in four wheel auto. This is extremely concering as I stoped using four wheel auto because of this past event. Again this engagement of the four wheel drive when the driver is not able to respond accordingly could lead to injury.

Transmission started shuddering very badly when taking off from a stop sign under wet conditions. This occurred when throttle was reduced after the rear wheels broke traction. GM knows about the transmission issues and the dealership has refused to repair it.

- Louisville, KY, USA

Had vehicle serviced under warranty several times for transmission issues. I was told by the dealer I had the most current software updates as of March of 2018. Vehicle continues to behave badly under certain circumstances. Transmission does not downshift properly if needing to accelerate hard. Engine RPM's rev to about 5,000 RPM and the transmission goes into too low of a gear, until the correct gear is found. This causes a delay in response that creates a safety hazard. Had only one instance where the truck accelerated hard out of a 90 degree turn even though only light pedal was used. Transmission shutters under light load when going up a slight upgrade. Dealership doesn't not want to acknowledge there is a problem. I was told I would be contacted if future updates were available and have heard absolutely nothing.

The transmission causes dangerous driving conditions. I have the same complaint as several others have reported.the transmission fails to downshift at lower speeds causing the hesitation when acceleration is needed. Pressing down further on the accelerator will lunge forward possible into crowed road way.

- Judsonia, AR, USA

The truck falls on it's face when accelerating after slowing down. The dealership says nothing is wrong. This is a dangerous situation. I have talked with other Canyon owners and they have the same problem.

- Baker, FL, USA

Automatic transmission. When going up a slight incline transmission stall on down shifting.driver must float the gas peddle or press for additional acceleration in order to climb a slight incline on regular road traffic. Incline could be no more than 15 degrees

- Saltillo, MS, USA

Between 20 and 40 mph truck fails to shift to a lower gear and increase speed. This causes the driver to keep pressing on the gas and then vehicle decides to shift to a lower gear and lurches forward, if you're in traffic this is when the vehicle is most dangerous and if the weather is severe (snow or ice) could cause you to loose control of vehicle. I've notified GM through their assistance center and have yet to hear from a GM engineer. The shifting problem is well documented on the web.

- Stafford, VA, USA

Truck transmission causes dangerous driving conditions I have same complaint as several others in the NHTSA customer complaint section. Basically the transmission fails to downshift at lower speeds causing the vehicle to hesitate when acceleration is needed until it downshifts appropriately. Pressing down hard on the accelerator will result in a downshift, but this is a potentially dangerous maneuver in crowed road conditions.
