NHTSA Complaint #10983898 — 2016 GMC CANYON

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.
