2017 GMC Canyon Engine Problems

Catastrophic engine failure. Piston #1 damage after a fuel injector issue. The truck just hit 100k miles. This left my husband stranded over an hour away. No check engine light or warning other than a loud pop and smoke. No warranty on the truck, I’ve been quoted $12k for a new engine. I have read MULTIPLE forums (one thread of 77 posts) of the same thing/similar thing happening.

The contact owns a 2017 GMC Canyon. The contact stated that while operating the vehicle, the temperature gauge would not operate and the vehicle would not properly accelerate while pressing the accelerator pedal. Also while operating the vehicle the contact had become ill with headaches and dizziness which required medical attention. Upon inspection, it was discovered that a hair-like fiber was present coming from the exhaust pipes. The vehicle was taken to the local dealer who informed that the temperature gauge and exhaust system was faulty and needed to be replaced. The hair-like fibers were not identified. The contact was concerned that the hair-like fibers had clogged the exhaust system causing carbon monoxide to enter the cabin of the vehicle. The manufacturer was notified of the failures. The vehicle was not yet repaired. The failure mileage was 52,000.

This is the 2nd time this has happened. The 1st time making a left onto route 23 from route 296 in Windham NY. Almost got T-Boned. Stalled wouldn't start. Waited 5 minutes and it started again. Ran rough then died again thankfully in a more opportune spot. MY car randomly & without warning loses all power and electric and shuts down. The 1st time I had it towed to Matthews GMC (where I purchased 4 pick ups) and they stated it was a NOX sensor and repaired it. Saturday this happened again while driving at 55 MPH and stalled on a blind curve (very scary). I left a complaint on this website to hopefully prevent a fatality. I thought I would recieve a response from you the NTSB but didn't. I went online and noticed there a a number of folks that had the same problem. Do you wait for fatalities before action is taken??

Truck turned just over 62000 miles and appears to have engine oil cooler line failure. No oil on engine just dripping in protective plastic between radiator and engine. Spraying back underneath when moving. Checked on lone and blogs are showing many others with same problem with near catastrophic failure. I have dealer appointment for Wednesday August 4th 2021 to have it checked.

OIL LEAKING FROM A HIGH PRESSURE OIL LINE. IT WAS A PIN HOLE IN MIDDLE OF LINE, RUBBER PART LOCATED BETWEEN RADIATOR AND ENGINE. IT WAS DISCOVERED AFTER BEING PARKED FOR AN HOUR IN DRIVEWAY, AFTER A 100 MILE DRIVE. IT HAPPENED WHILE DRIVING BECAUSE THE OIL WAS EVERYWHERE AROUND ENGINE AND ON INSIDE OF TIRES.THIS WAS A VERY SIGNIFICANT LEAK. LOST PINTS OF OIL. WHEN I STARTED CAR TO CHECK FOR LEAK IT COULD BE CLEARLY SEEN PUSHING OUT WITH PRESSURE. THE PLACEMENT OF THIS HOLE MAKES IT HARD TO BELEIVE THAT ANYTHING COULD OF PUNCTURED IT. FROM SOME SEARCHING IT SEEMS THIS IS NOT AN UNCOMMON PROBLEM. THERE ARE CLAIMS THAT THE BURST IS DUE TO STARTS IN COLD WEATHER. THE DAY IT HAPPENED WAS 1/1/21, IT WAS COLD BUT NOT EXTREME I WOULD SAY LOW 30'S F I AM FILING THIS AFTER TRUCK WAS BROUGHT TO SHOP, I DID NOT TAKE PICTURES OR VIDEO, REGRETTABLE. OF COURSE THIS WAS (IS) A MAJOR INCONVENIENCE, A MESS IN DRIVEWAY ETC.BUT I CONSIDER MYSELF LUCKY THAT MY ENGINE DID NOT GO ON FIRE. FEEL FREE TO CONTACT ME FOR ADDITIONAL INFO

GM HAD A RECALL ON THE 3.6 LGZ EQUIPPED IN TRUCKS IN CANADA. COLD WEATHER CAUSED OIL PUMP TO OVER PRESSURIZING OF OIL AND DAMAGE TO OIL COOLER AND LINES. LEAKING OIL IN TO ENGINE COMPARTMENT AND ON ROADWAY. THIS HAS HAPPENED TO ME TWICE NOW ONCE IN MARCH OF 2018 AND NOW AGAIN IN NOVEMBER 2019. DOING RESEARCH THIS IS A COMMON COMPLAINT. I WOULD LIKE NATIONAL HIGHWAY TRAFFIC SAFETY DEPARTMENT TO LOOK INTO THIS AN DO SIMILAR RECALL AS CANADA. HERE IN MINNESOTA IT GETS AS COLD OR COLDER THAN CANADA.

VEHICLE HAS 6600 MILES- WHILE NORMAL DRIVING AROUND TOWN, NOTICED A GASOLINE/OIL SMELL. AFTER BEING PARKED FOR 5 MINUTES RECIEVED A WARNING MESSAGE TO TURN OFF THE ENGINE DUE TO LOW OIL PRESSURE, THEN NOTICED A LARGE POOL OF OIL SPREADING UNDER THE ENGINE BAY OF THE TRUCK. THIS IS THE SECOND TIME OIL HAS LEAKED FROM THE ENGINE, FIRST REPAIR PERFORMED BY THE DEALER WAS TO REPLACE AN OIL COOLER HOSE. CONTACTED DEALER SERVICE DEPARTMENT, THEY SAID THEY HAD NEVER SEEN THIS ISSUE BEFORE. CONTACTED DEALER WHERE TRUCK WAS PURCHASED AND THEY HAVE REPAIRED THIS ISSUE MULTIPLE TIMES BY SWAPPING THE OIL PUMP FOR ONE WITH LOWER FLOW RATES (SIMILAR TO/SAME AS GM RECALL #N1821800260, WHICH DOESN'T YET APPLY TO THIS MODEL SOMEHOW).

DURAMAX 2.8 ENGINE SUFFERED GCATASTROPHIC ENGINE FAILUREH AT LESS THAN 72,000 MILES. DOCUMENTATION AVAILABLE TO SHOW ENGINE HAS RECEIVED PROPER MAINTENANCE. THIS OCCURRED IN CENTER LANE OF I-95 IN HEAVY TRAFFIC. THIS OCCURRED ON 07SEP18 IN STAFFORD VA.

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.

The contact owns a 2017 GMC Canon. The contact stated while driving 70 MPH, the check engine warning light illuminated along with the following displayed message "ISSUE WITH EXHAUST SYSTEM REDUCE ENGINE POWER TAKE TO THE DEALER IMMEDIATELY", as the vehicle slowed down drastically not allowing the driver to accelerate over 20 MPH. The contact stated that the vehicle was towed to the dealer where the failure was diagnosed as the diesel particulate filter would not complete a burn. A manual regeneration was completed. The contact stated that the failure recurred after 2,500 miles in November 2022 and the vehicle was taken to the dealer, Kelley Buick GMC (255 W Van Fleet Dr, Bartow, FL 33830) where another manual regeneration was completed. The contact stated that the dealer informed him that if the failure reoccurred, he would need to purchase a filter for $2,000. The contact stated that the vehicle failed to inform when a burn was needed as other diesel vehicles were equipped with the burn alert system along with a switch to complete the burn. The manufacturer was notified of the failure and stated there were no recalls for the failure. The failure mileage was approximately 3,000.
