2017 GMC Canyon

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 transmission shudders terribly. It is available for inspection. It is unsafe because while in traffic situations, it doesn't get up to speed correctly. It is as if it can't find the gear, it feels like it is about to stall. It is not dependable to stay at a speed, or increase speed. The dealership said that changing the transmission fluid would help, and it did for a while. The problem came back, we had the fluid changed again. The problem came right back again.

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.

VEHICLE STALLED WHEN I WAS MAKING A LEFT TURN ONTO ROUTE 23 FROM ROUTE 296 IN WINDHAM NY. CAR SHUTTERED AND STALLED. ALMOST GOT T-BONED BY A SEMI. EXTREMELY LUCKY THAT I WAS ABLE TO ROLL BACKWARDS ONTO THE BRIDGE BEHIND ME. I DID GO ONLINE AND SAW THAT WERE OTHER OWNERS WITH THE DURAMAX DIESEL THAT EXPERIENCED SIMILAR PROBLEMS. THIS COULD HAVE BEEN A FATAL ISSUE. I'M ACTUALLY WORRIED ABOUT DRIVING THIS PICK UP. CONTACTED THE DEALER AND THEY TOLD ME WITHOUT THE ERROR CODE THEY COULDN'T HELP ME. DISCONNECTED THE BATTERY TO CLEAR THE CHECK ENGINE LIGHT. ANY SUGGESTIONS?

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).

2017 GMC CANYON EQUIPPED WITH DIESEL ENGINE WILL SPORADICALLY SHUT-OFF WHILE OPERATING WHEN DRIVING WITH A TANK THAT IS LESS THAN 1/4 FULL. ON 1/31/19 (ODOMETER ~14200 MILES) VEHICLE WAS DRIVING FINE WITH AN AMBIENT AIR TEMPERATURE OF ROUGHLY 0F, FUEL TANK AT 1/3, WHEN ALL OF SUDDEN THE ENGINE DIED IN TRAFFIC WITH NO WARNING. VEHICLE THEN NEEDED TO BE TOWED TO THE DEALERSHIP FOR SERVICE AT WHICH POINT THEY COULDN'T FIND ANYTHING WRONG WITH IT. AGAIN ON 3/4/19 (ODOMETER ~15100 MILES) VEHICLE WAS DRIVING FINE WHEN THE DASH LIT UP WITH MULTIPLE CODES AND TRUCK WENT INTO REDUCED POWER MODE, AMBIENT AIR TEMPERATURE 10F GAS TANK AT 1/8TH. GOT OUT OF TRUCK AND IT SMELLED LIKE IT WAS ON FIRE. CALLED TO HAVE VEHICLE TOWED TO DEALERSHIP. VEHICLE KEPT FOR MULTIPLE DAYS AT DEALERSHIP, DEALER WORKED WITH GM TO IDENTIFY AN ISSUE AND NO FIX WAS FOUND. DEALER CALLED TO INSTRUCT ME TO NOT DRIVE THE VEHICLE WITH LESS THAN 1/4 TANK DURING WINTER AND ALSO MENTIONED THAT THIS HAS BEEN AN ISSUE WITH A FEW OTHER CANYON AND TERRAIN DIESEL MODELS. GM NEEDS TO FIND A FIX FOR THIS! IT IS TOTALLY UNSAFE AND UNACCEPTABLE TO HAVE A TRUCK THAT WILL UNEXPECTEDLY LOOSE TOTAL POWER WHEN DRIVING DUE TO A DESIGN FLAW IN THEIR SYSTEMS.
