2016 GMC Canyon

VEHICLE DOES NOT RESPOND TO ACCELERATION COMMAND WHILE ENTERING A HIGHWAY OR DURING HIGHWAY DRIVING, INCREASING THE RISK OF COLLATION WITH OTHER VEHICLES DUE TO TRANSMISSION FAILURE, SUSPECT THE TORQUE CONVERTER NOT WORKING PROPERLY. THIS IS A MAJOR AND WELL KNOWN ISSUE, GM CONTINUES TO IGNORE AND I DO NOT WANT TO BECOME THE NEXT STATISTIC DEAD IN US HIGHWAYS. THE VEHICLE IS MOVING, DURING A RED TRIANGLE YIELD SIGN ENTERING THE HIGHWAY, THE VEHICLE WILL NOT RESPOND TO ACCELERATION COMMAND CAUSING A BOTTLE NECK OF TRAFFIC BEHIND ME AND HIGH RISK OF BEING REAR ENDED. THIS IS A SERIOUS DEFECT AFFECTING THE TRANSMISSION, IT NEEDS TO BE INVESTIGATED AND RESOLVED AS SOON AS POSSIBLE.

VEHICLE FREQUENTLY SHUTS OFF DURING BRAKING OR WHILE STOPPED AND MUST BE RESTARTED BEFORE THE VEHICLE CAN OPERATE AGAIN. VEHICLE EXPERIENCES VIOLENT GEAR CHANGES AND SIGNIFICANT LAGGING DURING PERIODS OF MODERATE ACCELERATION AT LOW SPEEDS. GEAR CHANGES RESULT IN EITHER SEVERE UNRESPONSIVENESS AND A GENERAL LACK OF ACCELERATION OR AN AGGRESSIVE GEAR CHANGE THAT JERKS THE VEHICLE AND SPINS THE TIRES.

TRANSMISSION CONSISTENTLY SHUDDERS WHEN ACCELERATING IN ALL DRIVING CONDITIONS AND SPEEDS, AND SOMETIMES GOES TO HIGHER RPMS WHEN ENGINE IS WARM AND RESTARTED. DEALER SAID THIS WAS NORMAL WHEN RECENTLY BROUGHT IN. IT WAS NOT SHOWING ANY CODES. DEALER SAID NOT TO KEEP 4X4 IN AUTO MODE. LESS THAN A WEEK AFTER RECEIVING TRUCK BACK FROM DEALER, A 4 WHEEL DRIVE WARNING MESSAGE WAS DISPLAYED AND THE CAR WOULD NOT GO INTO 4 WHEEL DRIVE OR AUTO. MESSAGE AND PROBLEM COMES AND GOES. SHUDDERING SHOULD NOT OCCUR AND KEEPING IN AUTO MORE DURING RAIN AND COLD WEATHER IS A SAFETY PRECAUTION THAT SHOULD NOT BE AN ISSUE.

THE THROTTLE AND TRANSMISSION FEEL AS THOUGH THEY WERE SEPARATELY DEVELOPED FOR TWO DIFFERENT VEHICLES AND JUST RANDOMLY MATCHED IN THE TRUCK. THE ACCELERATOR IS VERY NON-LINEAR AND UNRESPONSIVE. THEN THE TRANSMISSION IS CONSTANTLY IN THE WRONG GEAR. THIS TRUCK IS A NIGHTMARE TO DRIVE IN TRAFFIC OR ON WINDY HILLY ROADS. YOU HAVE TO CONSTANTLY GUESS WHERE YOUR FOOT SHOULD BE TO GET ANY KIND OF STABILITY OR ACCELERATION FROM THE TRUCK. IF YOU ARE TRYING TO PULL OUT IN TRAFFIC YOU BETTER BE PREPARED TO HAVE A LOT OF ROOM BECAUSE IT MIGHT JUST SHAKE AND SHUTTER BEFORE FINDING A GEAR AND ACTUALLY ACCELERATING. THIS IS DANGEROUS AND I FIND IT ODD THAT THERE HAVENT BEEN COLLISIONS ATTRIBUTABLE TO THIS. IF ANYONE FROM GM IS READING THIS, KNOW THIS WILL BE THE LAST GM PRODUCT I EVER BUY. EITHER YOU DONT KNOW HOW TO ENGINEER A VEHICLE, OR YOU SIMPLY JUST DONT CARE ABOUT YOUR CUSTOMERS. IM GUESSING THE LATTER.

IGNITION WILL NOT FULLY TURN OFF AND RELEASE KEY WHEN TRUCK IS PLACED IN PARK. I'M ADDITION IGNITION AND KEY BECOME VERY HOT TO THE TOUCH AFTER DRIVING FOR OVER 20 MINUTES (TEMP OUTSIDE IS COOL 50-60). TRUCK WILL EVENTUALLY TURN OFF AND RELEASE THE KEY AFTER RESTARTING AND SHIFTING THROUGH ALL GEARS MULTIPLE TIMES (TURNING OFF, BACK ON, SHIFTING, ETC.). ALREADY ATTEMPTED CLEANING KEYS (BOTH SETS) WITH NO CHANGE IN BEHAVIOR.

TOUCH SCREEN AND IN DASH DIGITAL SPEEDOMETER RANDOMLY CHANGES ON ITS ON, THE TOUCH SCREEN WILL NOT RESPOND AND CHANGE RADIO STATIONS, VOLUME, CONTACT ON STAR, TRY TO USE PROJECTION OPTION, MOVE THE MAP ON GPS, AND CHANGE THE DIGITAL SPEEDOMETER FROM SPEED LIMIT TO RADIO STATIONS. ON MULTIPLE OCCASIONS WHILE DRIVING AT NIGHT THE ENTIRE DASH, RADIO, GAUGES LIGHTS EVERYTHING WENT BLACK RANDOMLY AS IF THE TRUCK WAS NOT TURNED ON BUT THE TRUCK CONTINUED TO DRIVE NORMAL AND AFTER WHAT LOOKS LIKE A RESET MAYBE 20-30 SECONDS EVERYTHING REBOOTS AS IF YOU JUST STARTED THE TRUCK. THEN IT'S BACK TO RANDOM BERSERK OUTBURSTS BY THE TOUCH SCREEN. TRANSMISSION STARTED GETTING JERKY BETWEEN GEARS AT 15K MILES AND HAS ONLY GOTTEN WORSE AT 35K MILES. ENTIRE VEHICLE SHAKES BETWEEN GEARS FRONT TO REAR AND BACK. THROUGH ALL GEARS. ALSO SOME STRONG HARD HITTING SHIFTS. DEALERSHIP HAS HAD VEHICLE 2 TIMES FOR BOTH ISSUES AND SEE NOTHING WRONG. THEY ARE CLEARLY LYING. GM WILL ALSO NOT HELP AND HAVE BEEN CONTACTED DIRECTLY.

VEHICLE HAS FREQUENT SLOW ACCELERATION WHEN ENTERING HIGHWAYS. I HAVE TO STEP ON THE ACCELERATOR HARD TO HAVE THE ENGINE PICK-UP SPEED, WHICH LEADS TO THE ENGINE OVER ACCELERATING. WHEN I SLOW DOWN ON SHARP ROAD TURNS AND ACCELERATE TO PICKUP SPEED THE TRANSMISSION SHIFTING THE GEAR HARD (MAKING A THUMP SOUND). HAVE GONE TO DEALER AT MERCED GMC AND TURLOCK CHEVROLET. BOTH STATE CAR IS RUNNING THE WAY GMC MANUFACTURED IT.

1) <POWERTRAIN> I HAVE 40K ON MY CANYON AND AM EXPERIENCING ACCELERATION ISSUES 0-40MPH 1-3RD SHIFT POINTS (AUTOMATIC TRANSMISSION). THE TRANSMISSION ACTS LIKE IT CANNOT DECIDE TO EITHER SAY IN 2ND OR SHIFT TO 3RD AND THERE'S A LAG OR SURGING AFFECT WHEN THIS HAPPENS. I HAD THE TRANSMISSION FLUID AND TRANSFER CASE FLUIDS CHANGED AR THE GM DEALERSHIP. PROBLEM STILL PERSISTS. 2) <OTHER> KEY GETS STUCK IN THE IGNITION. WHEN PLACING THE TRUCK IN PARK THERE'S AN INTERNAL RELAY/SWITCH WITHIN THE SHIFTER THAT IS SUPPOSED TO ACTIVATE A RELAY/UNLOCK SIGNAL TO THE KEY TUMBLER IN THE STEERING COLUMN. THIS DOESN'T ALWAYS HAPPEN AND THE KEY WON'T TURN TO THE OFF POSITION TO ALLOW IT TO BE RELEASED. I HAVE TO TURN THE KEY TO THE ACC POSITION PUT THE TRUCK IN DRIVE THEN BACK INTO PARK TO GET THE RELAY/SWITCH TO DIS-ENGAGE THE KEY POSITION FROM BEING LOCKED IN ACC.

TL* THE CONTACT OWNS A 2016 GMC CANYON. EVER SINCE THE VEHICLE WAS PURCHASED, THE VEHICLE HAS PULLED TO THE RIGHT. ADDITIONALLY, ON SEVERAL OCCASIONS, THE VEHICLE INDEPENDENTLY ACCELERATED. THE CONTACT ALSO STATED THAT THE TRANSMISSION WAS SLIPPING WHILE THE VEHICLE WAS BEING DRIVEN. THE VEHICLE WAS TAKEN TO AL SERRA GMC (LOCATED AT 6201 SAGINAW RD, GRAND BLANC, MI 48439, (810) 202-0226) WHERE IT WAS DIAGNOSED THAT THE ENTIRE STEERING COLUMN WAS MISALIGNED AND NEEDED TO BE REPLACED. ADDITIONALLY, THE BRAKE ROTORS NEEDED TO BE REPLACED. THE VEHICLE WAS REPAIRED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 9,735.
