2016 GMC CANYON Complaints

TRANSMISSION SEEMS TO BE CONFUSED. IT WILL HESITATE DURING ACCELERATION AND SHIFT UP AND DOWN WHILE COASTING. MOST SLUGGISH SHIFTING OCCURS DURING LOWER SPEEDS. IT ALSO HAS A HABIT OF DOWNSHIFT TO LOW GEAR WHILE COASTING DOWNHILL. ALWAYS SEEMS TO BE FIGHTING WITH ITSELF!

I PURCHASED A GM 2016 CANYON IN OCTOBER, 2016 AND HAD DRIVEN IT NEARLY SIX MONTHS WHEN THE EVENT DECRIBED HERE OCCURRED. UP UNTIL APRIL 16, 2017, I HAD HAD NO PROBLEMS WITH THE TRUCK. HOWEVER, ON EASTER SUNDAY AFTERNOON, WHILE ATTEMPTING TO SLOW MY CANYON DOWN AND PREPARING TO STOP AT A STOP LIGHT, THE ENGINE SEEMED TO GO FORWARD OF IT'S OWN VOLITION AND THE TRUCK DID NOT RESPOND TO MY EFFORTS TO BRING IT TO A COMPLETE STOP. CONSEQUENTLY, MY VEHICLE STRUCK THE VEHICLE IMMEDIATELY IN FRONT OF IT. A SUBSEQUENT INTERNET SEARCH REVEALED THAT A TECHNICAL SAFETY BULLETIN ISSUED BY GM IN SEPTEMBER OF 2016 DESCRIBED THIS EVENT AS HAVING OCCURRED TO 2016 CANYON DIESEL ENGINES. MY VEHICLE HAS A GASOLINE ENGINE; NONETHELESS THE CONDITION WAS DESCRIBED IN THE BULLETIN (TSB 16-NA-276) AS: "SOME CUSTOMERS MAY COMMENT ON A SHUDDER AT LOW SPEEDS, AN IDLE SURGE WHEN STOPPED OR APPROACHING A STOP." THIS IDLE SURGE DESCRIBES EXACTLY WHAT HAPPENED TO MY VEHICLE AS I WAS ATTEMPTING TO SLOW DOWN AND STOP AT A RED LIGHT. ALTHOUGH THERE WAS NO DAMAGE DONE TO MY VEHICLE, THE OFFICER WHO INVESTIGATED THE ACCIDENT WOULD NOT LET US DRIVE OUR VEHICLE UNTIL IT HAD BEEN EXAMINED AND EVALUATED BY OUR LOCAL GM SERVICE DEPARTMENT. THE SERVICE PERSONNEL ADAMANTLY MAINTAINED THEN (AND NOW) THAT THE ACCIDENT DID NOT HAPPEN AS I DESCRIBED IT. I HAD TO CONTACT GMC CUSTOMER CARE CENTER TO HAVE 15 MINUTES WORTH OF DIAGNOSTICS DONE PER COMPUTER, ESP THE ENGINE CONTROL MODULE. THE TSB STATES: "IF YOU ENCOUNTER A VEHICLE WITH THE ABOVE CONCERN, REPROGRAM THE ENGINE CONTROL MODULE WITH THE LATEST CALIBRATIONS." LUCKILY, THE GENTLEMAN AT THE CUSTOMER CARE SERVICE WAS ABLE TO INTERVENE AND HAVE THE ENGINE CONTROL MODULE EVALUATED AND DOCUMENTATION THAT THERE WERE NO PROBLEMS WITH IT OR ANY OTHER "CONTROL MODULES" PROVIDED TO US BY OUR LOCAL GM SERVICE DEPARTMENT.

RODENTS ARE EATING THE WIRING IN MY NEW TRUCK. I'VE DRIVEN A NISSAN TRUCK FOR 18 YEARS WITH ZERO ISSUES WITH RODENTS. I PURCHASED THE NEW CANYON IN JULY OF 2016, AND WITHIN 6 MONTHS, ENTIRE WIRING HARNESSES WITH 7 WIRES ARE CHEWED COMPLETELY THROUGH. THE DEALER REFUSES TO COVER DAMAGE UNDER WARRANTY.

I PURCHASED A 2016 GMC CANYON IN JULY 2016. I NOTICED HESITATION WHEN I ACCELERATE, ESPECIALLY WHEN IN TRAFFIC, GOING UPHILL OR ROUNDING CORNER. I RESEARCHED MANY FORUMS AND FOUND THE TRANSMISSION HAS A LEARNING PERIOD WHERE IT DOES THIS AND ADAPTS TO YOUR DRIVING, NORMALLY WITHIN THE FIRST 1000 MILES. HOWEVER, IT HAS BEEN 13,000 MILES LATER AND ALMOST A YEAR, AND IT CONTINUES TO HAVE THIS HESITATION AS BAD IF NOT WORSE THAN IT DID INITIALLY. GMC HAS CHECKED IT OUT, GAVE IT A TEST DRIVE AND SAID IT SHOWS NO CODES SO THEY OFFER NO HELP. ALL OF MY PASSENGERS NOTICE THIS HESITATION WHEN IT HAPPENS. THE BEST WAY TO DESCRIBE THIS HESITATION IS WHEN YOU PUSH THE GAS, THE TRUCK ACTS LIKE IT DOESN'T WANT TO GO AND IT BECOMES SHAKEY. IN SITUATIONS WHERE I'M MERGING ONTO TRAFFIC, THIS COULD BE DANGEROUS, AS I HAVE HAD TO FLOOR IT TO MAKE IT ACCELERATE. FOR A NEW VEHICLE, THIS IS UNACCEPTABLE AND I FELT SAFER IN MY 2001 SIERRA THAN I DO IN THIS. THE FACT THAT GMC WILL NOT OFFER ANY WAY TO FIX THIS ADDS TO THE FRUSTRATION. NO MATTER WHAT THEY SAY, IT IS NOT NORMAL FOR A VEHICLE TO DO THIS.

THE TRANSMISSION DOES NOT SHIFT PROPERLY, WHEN YOU SLOW DOWN FROM APPROX 40 TO 20 THEN STEP ON THE GAS THE TRUCK HAS A LONG HESITATION. IT IS VERY UNSAFE AND IS GOING TO CAUSE AN ACCIDENT. THE TRUCK WANTS TO STALL OUT UNLESS YOU FLOOR IT.

REAR WINDOW DEFROSTER ON PASSENGER SIDE OF SLIDING REAR WINDOWS DOES NOT WORK. MANY COMPLAINTS ONLINE OF SAME PROBLEM.

TL* THE CONTACT OWNS A 2016 GMC CANYON. THE CONTACT STATED THAT WHILE DRIVING AT VARIOUS SPEEDS, THE ACCELERATOR PEDAL WAS ENGAGED AND THERE WAS A DELAYED RESPONSE OF SEVERAL SECONDS. THE CONTACT STATED THAT THE FAILURE OCCURRED WITHOUT ANY WARNING. THE FAILURE RECURRED SEVERAL TIMES. THE VEHICLE WAS TAKEN TO THE DEALER. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 11,000.

WHEN ATTEMPTING TO TURN LEFT ONTO A HIGHWAY FROM A STOP SIGN, THE TRANSMISSION FAILED TO ENGAGE, WITH A 2-SECOND DELAY BEFORE ENGAGING AND ACCELERATING INTO THE TURN. AS A RESULT OF THE DELAY, I WAS NEARLY HIT BY ONCOMING TRAFFIC. THIS VEHICLE MODEL, 2016 GMC CANYON, HAS A HISTORY OF NOT BEING IN THE PROPER GEAR WHEN STOPPED OR MOVING AT SPEEDS BELOW 3-5 MPH. THIS ISSUE HAS HAPPENED TO ME OVER 100 TIMES IN THE FIRST 6 MONTHS OF OWNERSHIP, BUT THIS WAS THE FIRST TIME I NEARLY HAD A DANGEROUS COLLISION. GMC SHOULD CORRECT THIS PROBLEM WITH THE TRANSMISSION NOT BEING IN THE PROPER GEAR FOR BEING STOPPED OR FOR EXTREMELY LOW SPEEDS. *TR

TL* THE CONTACT OWNS A 2016 GMC CANYON. WHILE DRIVING 55 MPH, THE CHECK ENGINE INDICATOR ILLUMINATED WITHOUT WARNING. IN ADDITION, THE BRAKES ENGAGED WITHOUT WARNING AND WITHOUT THE ASSISTANCE OF THE DRIVER. THE VEHICLE DECREASED TO SPEEDS OF 20-30 MPH. THE CONTACT COULD NOT ACCELERATE BEYOND 30 MPH. IN ADDITION, OIL LEAKED ONTO THE EXHAUST MANIFOLD AND CREATED A BURNING ODOR. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 4,000.

ABOUT EVERY 3-5 WEEKS THE ENGINE WILL ACCELERATE BY ITSELF. THE FIRST 3 TIMES IT ACCELERATED TO 3,000 RPM, THE LAST 4 TIMES 4,000 RPM. SO FAR AS I CAN TELL IT DOES THIS WHEN SHIFTING FROM 1ST TO 2ND. I TOOK IT TO THE DEALER AND THEY SAID THEY COULD NOT DUPLICATE THE PROBLEM SO THEY COULD NOT FIX IT. HAPPENS IN MOTION ON CITY STREET OR IN PARKING LOTS. I HAVE STANDARD TRANSMISSION SO WHEN IT HAPPENS I CAN LEAVE CLUTCH IN, TURN OFF ENGINE AND RESTART. PROBLEMS STARTED AT ABOUT 3,400 MILES. STILL DOING IT.
