2016 GMC Canyon

Power steering and stabilitrak intermittently go out. Latest episode resulted in power steering failing at low speeds and continuously chiming for service. Stabilitrak error message also comes in notifying service. This issue has happened in the past where I would turn on the vehicle and the power steering would be out without a service warning. After shutting the vehicle off and on again power steering would be back. In the last attempt to drive this error came up and attempting to turn the vehicle off and on again did not fix. It was not until I was about 15 miles down the road that the power steering kicked back in. I believe this may be the same issue as the recall of the 2015 models.

The contact owns a 2016 GMC Canyon. The contact stated while driving 50 MPH, the vehicle lost power steering functionality. There were no warning lights illuminated. The contact pulled over to the side of the roadway and called a friend for assistance. The contact had experienced the failure on three separate occasions. The vehicle was not taken to be diagnosed or repaired. The manufacturer was not notified of the failure. The approximate failure mileage was 62,000.

At random times, the power steering will cut off making the vehicle very difficult to steer. This can happen when starting or while driving. It will not come back on until the vehicle is shut off. Sometimes restarting works and sometimes it does not. I have put dielectric grease on the connecters behind the airbag. This seems to help for a while. The condition matches NHTSA Campaign number 21V213000 for power steering issues. However, many 2016 models experience the exact same issue. The dealer will not help. This is my daughters truck and she is not big/strong enough to overcome the loss of power steering.

The incident occurred while I was bringing my 18 month old daughter home from daycare. As I was initiating a left hand turn across traffic, the truck suddenly suffered a total loss of power steering. I had already committed to the maneuver when I realized what was happening, but thankfully was able to complete the turn despite struggling to apply enough force to the wheel. I then immediately pulled to the side of the road and parked. I believe multiple warning messages displayed, but I was concentrating on reaching safety and didn't see them all. I did see that one of the messages indicated Stabilitrack had failed. After the vehicle sat for several hours, I returned and started the vehicle, at which point the errors had cleared and power steering had been restored, at least temporarily. I took the truck to a non-dealer repair shop, who did discover a stored error code: C0545 - Steering Wheel Torque Sensor Malfunction. As the sensor is highly integrated into the steering system, the repair required the replacement of the entire rack and pinion component. In order to avoid living with the threat of intermittent power steering failure endangering my family at any moment, I had no choice but to authorize this very expensive repair.

The contact owns a 2016 GMC Canyon. The contact stated that while his son was driving 55 MPH and making a right turn, the steering became difficult to turn. The contact stated he also experience the failure twice. The contact stated the stabilitrak warning light was illuminated. The vehicle was not diagnosed or repaired. A dealer was not contacted. The manufacturer had been informed of the failure. The failure mileage was approximately 62,000. Vehicle has a faulty steering. Problem comes on sporadically while driving and making turns. It has happened to me 2 times almost forcing the consumer into the next lane.

We are always getting a code P1478 on our truck when we add def fuel in it when it is time to do so. We have tried to clear it out on our own but never goes away and have to end up taking it to the dealership to get it done. They said it's because the soot it built up. We have always used Blue Def in our vehicles. There was a recall on this system where they have to reset the system or a sensor. I don't understand whey this is always happening, The drivers seat was recalled once for it not being manufactured corrected. It fabic held up a few years when we got the few years when we got the vehicle and it is has done it again. We have asked the dealership about about another recall on the seat and they said they haven't seen one. We have tried to get it fixed on our own but no one have the fabic to do it. It isn't but together very well at all.
