2017 GMC Canyon

TRANSMISSION CONTINUALLY HAS ISSUES WITH THE FIRST TO SECOND GEAR CHANGE, SHUDDERS AT LOW SPEEDS AND WHEN DECELERATING, AND PRODUCES A LOUD 'CLUNK' NOISE WHEN WHEN REVERSE GEAR IS ENGAGED. IN ADDITION TO THE ' CLUNK', THE BODY OF THE VEHICLE IS SUBJECT TO A RAPID MOVEMENT AS THE REVERSE GEAR IS ENGAGED. THE VEHICLE HAS BEEN RETURNED TO THE DEALERSHIP IN ORDER TO RESOLVE THE ISSUE HOWEVER, I HAVE BEEN TURNED AWAY FOR REPAIRS AS THEY CLAIM IT IS A CHARACTERISTIC TRAIT OF THE 8L90 ( 8 SPEED) TRANSMISSION. THE TSB OF CHANGING THE TRANSMISSION FLUID TO THE MOBIL1 DID TEMPORARILY MASK THE ISSUE. THE ISSUE HAS RETURNED AND WORSENED AND THIS HAS HAPPENED TO MANY PEOPLE. ON TO THE SUSPENSION, MY VEHICLE IS EQUIPPED WITH THE ' ALL-TERRAIN' SUSPENSION PACKAGE. MY VEHICLE IS SUBJECT TO A VERY LOUD SUSPENSION ' SQUEAK' ALONG WITH A POOR RIDE.

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

WE HAVE A 2017 GMC CANYON DIESEL WITH 56570 MILES ON IT. WHILE WE WERE DRIVING DOWN THE STREET (IT WAS RAINING) GOING ABOUT 30 MILES AN HOUR AND ALL OF THE SUDDEN THE "SERVICE STABILITRAK" CENSOR CAME ON AM IT INSTANTLY PUT THE BRAKE ON. WE TURNED THE TRUCK ON AND OFF. OVER AND OVER LETTING IT SIT FOR MORE THAT A MINUTE COMPLETELY AND STILL NOTHING....WE WERE DOWN THE STREET FROM OUR HOUSE AND MY HUSBAND HAD TO PUSH IT HOME. THIS COULD HAVE BEEN SUCH A DANGEROUS SITUATION 😳 THERE HAPPENED TO BE NO ONE BEHIND US BUT IT WAS SO ABRUPT THAT IF WE DID THEY MOST DEFINITELY WOULDN'T HAVE HAD TIME TO STOP AND CRASHED RIGHT INTO US. I WILL BE CALLING GMC IN THE MORNING BUT WE WERE DEFINITELY GRATEFUL WE MADE IT HOME SAFELY THOUGH PUSHING A TRUCK THROUGH THE RAIN UP HILL WAS NOT FUN FOR MY HUSBAND. WE HAVE READ UP ON THIS AND WAS COMPLETELY SURPRISED HOW MANY PEOPLE HAVE HAD THIS SAME PROBLEM. YOU DEFINITELY SHOULD HAVE SOMETHING PUT OUT FOR THIS LETTING PEOPLE KNOW....THIS IS CRAZY GM HAS EITHER BASICALLY IGNORED THIS OR SIMPLY DOES NOT CARE FOR SAFETY. I ABSOLUTELY LOVE MY TRUCK BUT THIS TRULY DISAPPOINTS ME I HOPE WE ARE NOT PUT IN THE SAME SITUATION AS ALL THESE OTHER FOLKS WHO WERE PUT THROUGH THE RINGER WITH NO RESULT FOR THIS ISSUE!

TRUCK WAS IN MOTION ON THE HIGHWAY TRAVELLING AT 110 KM/HR WHEN THE POWER ASSISTED POWER STEERING WARNING LIGHT CAME ON AND THE VEHICLE LOST ALL FUNCTIONALITY TO STEER THE VEHICLE. I PULLED OVER TO THE HIGHWAY SHOULDER AND SHUT THE VEHICLE OFF. I WAITED TWO MINUTES AND THEN STARTED THE VEHICLE . THE WARNING LIGHT WAS STILL VISIBLE, BUT THE POWER ASSISTED STEERING WAS WORKING INTERMITTENTLY. I TOOK THE VEHICLE TO THE DEALER FOR INSPECTION.

WITH THE VEHICLE IN PARK AND THE STEERING LOCKED AND THE KEY REMOVED. PUT THE KEY IN THE IGNITION AND IT WILL NOT TURN. SO IMMEDIATELY YOU THINK THE STEERING MUST BE TURNED SHARP EITHER ONE WAY OR THE OTHER AND A LITTLE PRESSURE OR JIGGLE WOULD LOOSEN IT. NOPE. IN FACT, THE WHEELS ARE POINTING STRAIGHT AHEAD. SO NEXT, ONE WOULD THINK IT MUST BE THE GEAR SHIFTER SAFETY WITCH MUST BE THE ISSUE AND A LITTLE JIGGLE OF IT SHOULD ALLOW YOU TO TURN THAT KEY. NOPE. SO, LET'S GET LOTS OF HELP AND HAVE SOMEONE JIGGLE THE WHEEL, WHILE ANOTHER JIGGLES THE GEAR SHIFTER AND STILL ANOTHER TRIES TO TURN THE KEY. NOPE. A BRIEF SEARCH OF THE INTERWEBS TELLS YOU THIS IS A PROBLEM OTHER HAVE EXPERIENCED. NOT A PROBLEM YOU WOULD EXPECT ON A NEW VEHICLE, BUT LET'S FACE IT, GM IS NOTORIOUS FOR STEERING COLUMN ISSUES. AND THE DEALER WANTS A GRAND TO FIX IT'BUT THEY DON'T KNOW WHAT THE PROBLEM IS EITHER. *TR

TRUCK STALLS AS IF IN NEUTRAL AFTER STARTING. UNFORTUNATELY, I HAVE TO LET THIS TRUCK RUN FOR T LEAST 10 MINUTES OR MORE BEFORE I CAN TAKE OFF. IF I START THE TRUCK AND PUT IT IN DRIVE ANY SOONER, TRUCK WON'T MOVE. ACTUALLY, IT RUNS THEN SEND TO SLAM (VERY HARD JERK) INTO DRIVE, STUDDERS, THEN FUNCTIONS NORMAL. I TOOK IT BACK TO DEALER AND THEY SAY THERE HAS BEEN MULTIPLE COMPLAINTS ABOUT THESE TRUCKS. I ALSO WAS TOLD GM PUT A STATEMENT OUT ABOUT THESE COMPLAINTS AND SAID THERE IS NOTHING THEY CAN DO TO FIX, IN SO MANY WORDS. DEALER SAY IT WILL GO AWAY. I'VE HAD THIS VEHICLE SINCE JULY 4 2019 AND STILL HAPPENING ALMOST EVERYDAY.

TL* THE CONTACT OWNS A 2017 GMC CANYON. THE CONTACT STATED THAT WHILE DRIVING DOWNHILL, THERE WAS A LOUD REVVING SOUND COMING FROM THE TRANSMISSION. THE CONTACT STATED THAT THE TRANSMISSION WAS SLIPPING. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC HOWEVER, THE MECHANIC WAS UNABLE TO DETERMINE THE CAUSE OF THE FAILURE. A DEALER WAS NOT CONTACTED. THE MANUFACTURER WAS NOT NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 155,994.
