2016 GMC Canyon

Power steering and StabiliTrack warning pops-up randomly and cuts off power steering assistance while I'm driving on the highway or on country roads. The power steering is very hard to maneuver. However, when it's safe to do so, I have to pull over on a safe place and have to restart my truck twice, in order to regain power steering. I have taken it to an independent mechanic and to a Chevy dealership on Merced. The dealership service tech informed me that in order to service the vehicle and find the code that is making this issue, that I would have to continue driving the truck and bring it in to the dealership with the power steering and StabiliTrack warning. According to the technician, they can't do much due to that they don't know what is causing the power steering to malfunction. I haven't been able to take it to the dealership because the warnings have occurred while I'm far away from a dealership or diagnosis area. Also, I will not risk my safety maneuvering a vehicle that has lost electric power steering around a city where lots of left or right turns are necessary to drive to a locality. This is the only vehicle I have to go to work or travel and fear for my safety when this happens. PLEASE HELP.

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.

ON JULY 2ND, I LOOKED WHERE MY CANYON WAS PARKED AND FOUND A SIGNIFICANT AMOUNT OF DIESEL FUEL ON THE GROUND. UPON FURTHER INSPECTION, I FOUND FUEL ALL OVER THE UNDERSIDE OF THE VEHICLE AND A SEVER LEAK FROM A HOSE. THE HOSE WAS RUBBING ON A CAN COMING FROM THE AC COMPRESSOR. THE VEHICLE DOES NOT LEAK WHEN PARKED (OTHER THAN DRIPPING) BUT LOOSES SIGNIFICANT FUEL WHEN IDLING OR DRIVING. THIS ISSUE LIKELY STARTED A FEW DAYS AGO BUT WAS NOT DISCOVERED UNTIL 7/2. THE FUEL ITSELF IS CLOSE TO SEVERAL HOT COMPONENTS INCLUDING THE TRANSMISSION, EXHAUST AND TRANSFER CASE.

TL* THE CONTACT OWNS A 2016 GMC CANYON. THE CONTACT STATED THAT THE FUEL TANK WAS MISSING THE METAL SKID PLATE AND FUEL LEAKED FROM THE VEHICLE. WHEN THE CONTACT APPROACHED THE VEHICLE, HE NOTICED THE FIRE DEPARTMENT WAS PRESENT TO INSPECT THE VEHICLE. THE CONTACT ALSO NOTICED A STRONG FUEL ODOR COMING FROM THE VEHICLE. THE VEHICLE WAS TOWED TO A REPAIR SHOP. THE VEHICLE WAS NOT TAKEN TO A DEALER OR INDEPENDENT MECHANIC FOR DIAGNOSTIC TESTING OR REPAIRS. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 18,446.

I BOUGHT A BRAND NEW 2016 CANYON, TEST DRIVE WENT WELL, ALTHOUGH I ADMIT IT PROBABLY WASN'T LONG ENOUGH. PURCHASED ON SUNDAY, AND DURING THE NEXT WEEK DRIVING I BEGAN NOTICING THE TRANSMISSION WAS NOT SHIFTING AT THE PROPER TIMES. LIKE MOST PEOPLE ON HERE, THE TRANSMISSION APPEARS TO BE VERY CONFUSED , ESPECIALLY WHEN DECELERATING INTO THE 20-35 MPG RANGE AND ATTEMPTING TO RE-ACCELERATE BACK UP. IT WILL MISFIRE OR BE VERY UNRESPONSIVE, AND THEN CLUNK AND JERK YOU FORWARD ONCE IT DECIDES TO CHANGE GEARS. IT ALSO DOES SOMETHING THAT I THINK IS EVEN MORE DANGEROUS WHEN YOU ARE GOING AROUND 30-40 MPG AND THEN SIMPLY LET OFF THE ACCELERATOR. IN THIS INSTANCE, I FEEL LIKE IT DOWN SHIFTS INSTANTLY AND IT FEELS LIKE THE TRUCK IS BEING PULLED BACK (INSTEAD OF SIMPLY COASTING LIKE I WOULD WANT), AND THEN AT SOME POINT IT "RELEASES" FROM THIS AND THE TRUCK ACTUALLY STOPS DECELERATING AND SPEEDS UP A BIT, EVEN THOUGH THE GAS HAD BEEN RELEASED MANY SECONDS AGO. THIS IS PARTICULARLY DANGEROUS IN STOP AND GO CITY TRAFFIC. I THINK THE OVERARCHING PROBLEM HERE IS THE SHIFT POINTS THAT THE ECM HAS DETERMINED (OR BEEN PROGRAMMED WITH). YOU CAN TELL THIS WHEN ACCELERATING FROM A STOP, MY TRUCK GETS TO THIRD GEAR BY 15 MILES PER HOUR AND NEVER GOES ABOVE 2K RPM'S??? I ADMIT I AM A BIT LIGHT-FOOTED ON DRIVING, WHICH COMPOUNDS THE PROBLEM BECAUSE I EVENTUALLY AM GIVING A SMALL AMOUNT OF ACCELERATION TO A TRUCK IN 4TH GEAR ONLY GOING 20 MPH, WHICH SUCK. I HAVE ALSO READ THIS WAS A COMMON PROBLEM ON 15 CANYON (OBVIOUSLY READ AFTER PURCHASE), AND GMC EVENTUALLY CAME OUT WITH A FEW FIXES, INCLUDING ECM PATCH UPDATES OR LOWER VALVE REPLACEMENT. I IMAGINE THAT MANY OF THE 2016'S WERE ALREADY OFF THE LINE BY THE TIME THESE '15 FIXES CAME OUT (IN APRIL 15 I BELIEVE), BUT THE DEALERSHIPS HAVE NOT RECEIVED ANY OF THESE FOR THE 2016.
