2017 GMC Canyon

TORQUE CONVERTER FAILS AT 12000 MILES FOR MANY. THERE IS A GMC NOTICE OUT SINCE 2016. MINE FAILED AT 16000 MILES AND THE ONE THEY REPLACED WILL LIKELY FAIL AGAIN IN ANOTHER 16K MILES. THIS IS BAD. I NOTICED IT WHEN I PRESSED ON THE ACCELERATOR AND AS I INCREASED SPEED UP TO 45 MPH. IT RATTLED AND ROCKED BADLY. THE GMC REPAIRMAN SAID, "YEAP.....EVER SINCE 2016 ALL THESE [XXX] TORQUE CONVERTERS HAVE BEEN FAILING IN THE CANYONS AND COLORADOS BECAUSE GM AND CHEVY CHANGED THE SIZE AND STRENGTH OF THE METAL USED IN ORDER TO REDUCE THE WEIGHT OF TRHE VEHICLE. WE WILL REPLACE IT, BUT I CAN ASSURE YOU IT WILL FAIL AGAIN AND YOU'LL HAVE TO BRING IT BACK TO USE FOR CHANGE OUT AGAIN." WOW....WHAT A BUNCH OF CRAP.

OWNED THIS 2017 GMC CANYON FOR 1 YEAR AND 1 MONTH WITH 5000 MILES WHEN IT DEVELOPED AN OIL LEAK. BROUGHT TO DEALER WHO FOUND THE OIL LEAK COMING FROM A "PINHOLE" IN THE OIL COOLANT HOSE. WHEN I RESEARCHED THIS SPECIFIC OIL LEAK ONLINE A FOUND A FORUM POST WITH MANY OTHER PEOPLE WHO HAVE HAD THIS SAME ISSUE SINCE THE 2015 MODEL YEAR. OTHER PEOPLE DID NOT NOTICE THE LEAK UNTIL ALL OF THEIR OIL HAD DRAINED AND HAD TO BE TOWED TO SERVICE. I NOTICED IT EARLY ENOUGH THAT I STILL HAD OIL WHEN I ARRIVED AT THE DEALERSHIP TO GET IT CHECKED OUT. IT LOOKS LIKE THIS IS STILL AN ONGOING ISSUE WITH THE 2018 MODELS TOO, BUT NOT MUCH IS BEING DONE BY GM TO PROACTIVELY FIX THE BAD HOSES.

NOX SENSOR POSITION 2 FAILED, SECOND OCCURRENCE, DIESEL VEHICLE ENTERED LIMP MODE. LIMP MODE IS DANGEROUS AND INDICATED DEF FLUID ISSUE. THIS IS A FALSE POSITIVE (AS DESCRIBED IN MANY PLACES ON THE INTERNET AND BY THE DEALER) AS A RESULT OF THE SENSOR FAILURE. FIRST DEALER DID NOT STOCK THE PART, DEALER 178 MILES AWAY HAD THE PART IN STOCK. LIMP MODE IS A CONTINUED DECREASE IN VEHICLE MAX SPEED. WHILE A FAILURE OF THE EXHAUST SYSTEM IS CRITICAL, IT SHOULD NOT BE ALLOWED TO PLACE AN OWNER AT RISK. BY THE TIME I REACHED THE SECOND DEALER, I HAD 4 MILES UNTIL THE VEHICLE WOULD DEGRADE TO 4MPH. I WAS ASKED TO LEAVE WITHOUT EXECUTION OF A CRITICAL STEP, BECAUSE GM DOCUMENTS DID NOT RECOMMEND THAT STEP AS PART OF THE REPAIR. 2 SCENARIOS EXIST, SENSOR FAILURE WITHOUT LIMP MODE AND FAILURE WITH LIMP MODE. IN LIMP MODE THE VEHICLE CANNOT BE DRIVEN LONG ENOUGH TO RESET THE FAILURE AND GM SHOULD INCLUDE THIS IN THE REMEDIATION. INCREMENTALLY, THE DEALER SHOULD HAVE A PROCESS TO RESET LIMP MODE TO ALLOW TRAVEL WITHOUT THIS MODE UNTIL THE NEXT IGNITION CYCLE. ALSO THIS WOULD BE A PREFERABLE SERVICE FROM ONSTAR. THE LIMP MODE IS GREAT FOR THE CASUAL ISSUE BUT CREATES A RISK TO LIFE AND LIMB FOR TRAVELERS AND SHOULD HAVE LIMITED OVER RIDE CAPABILITY. BEING THE FAILURE HAPPENED ON A MAJOR HIGHWAY, IN A CONSTRUCTION AREA WITH CONCRETE BARRIERS ON EACH SIDE THIS CREATED GREAT STRESS. NO AMERICAN SHOULD OWN A VEHICLE COSTING $41000 THAT LEAVES YOU AT RISK OR STRANDED. THIS IS IRRESPONSIBLE.
