2016 GMC Canyon power train problems

“At random the power steering and traction control turn off making it difficult to drive.. This happens randomly and has become unable to steer. Once the vehicle is turned off for a period of time you can start it up and the steering returns. The issue was reported in the 2015 models. That recall needs to extend into the 2016 models since most of the parts were most likely manufactured tot eh same specs as the 2015. The vehicle was diagnosed by an independent repair shop. The dealership wanted $200 for just the diagnostics. Every time this happens it becomes very difficult to drive and is a safety issue. The issue first appeared 2 months ago and after the restart stopped. Then all of a sudden it seems to occur daily.”

“Transmission has been shuddering since 15,000 miles till now. Dealerships says it's normal on these transmissions, 6 fluid and filter changes and now at 72,000 miles the transmission is failing just outside of warranty. They scammed me and kept my transmission barely alive until warranty ran out and now they want 8k-10k for a replacement. They knew. Dash goes crazy from the touch screen to the digital information screen in the speedometer. They say it's normal and happens on all the units. But it's distracting and has been messing up since bought the truck new. Again they just kept saying it was nothing they can do. Now they say it needs to be replaced after my warranty has run out. DEF system is failing conveniently after the warranty has run out. It's dangerous because they programmed the truck to go into limp mode when anything emissions related fails stranding me anywhere at anytime. Emission failures like sensors should not restrict travel. This is a major issue with the diesels in these trucks and they need to be forced to remove anything that's not dangerous to the health of the engine or drive train from the software or hardware from being able to…”

“Complete loss of power steering and traction control while driving. Very difficult to make turns. Would have to pull off the road and restart vehicle to fix problem. I have not taken it to a service center. It has not been inspected. Warning lights for loss of stabilitrak do come on.”

“I have not been in an incident yet, but when I slow down coming off the highway and try to come back up to traffic speed the the transmission bucks or shutters. Also when starting from a red light or stop sign the truck bucks or shutters very notable in 3-4-5th gear. I watched the tachometer and it shutters most of my drive. In all fairness, I have not brought it to the dealership yet. I see other people are having this problem with the Canyons and Colorado also. Please advise!”

“Driving and the Stabilitrak warning comes on as well as the Power steering warning. later after the vehicle is turned off it will not restart (no crank, no Start) and there is no communication with the ECM until it has had the battery disconnected for an extended period. This is very dangerous losing power steering and stabilitrak while driving is going to cause an accident. I would like to see a recall on the 2016 like there is on the 2015 with this same issue. I have not had the issue repaired yet. waiting to get it into a shop who tells me they will likely need to replace the Rack and Pinion on this truck to correct the issue.”

“Ignition key randomly will not release from switch. The key is stuck in the ignition in the accessory position which in turn kills the battery. As far as I can tell (and I have read about and experienced this problem for many months) the root cause is the gear shift assembly or Part # 23397472. It is not reliably returning the confirmation, to the solenoid lock on the ignition switch, that the transmission is in PARK reliably. For the first time last w/e my dealer admitted this is a problem and that replacing 23397472 usually resolves the issue. I need GM to take responsibility and activate a recall”
