2017 GMC Canyon

The contact owns a 2017 GMC Canyon. The contact stated that while driving at an undisclosed speed, the vehicle shuddered abnormally. The vehicle was taken to the dealer, and the engine oil was changed several times, but the failure persisted. The vehicle was taken to an independent mechanic, who replaced the serial gateway module, but the failure recurred. The vehicle was then taken to a transmission specialist, who determined that the transmission had failed and needed to be replaced; however, the transmission was on backorder. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 96,000.

there seems to be electrical issue. the fan won't stop running even when shut off. the thermostat stop working with pretty low milage along with the tire sensors. Fixed the previous issues. Furthermore, while driving the vehicle stop working and had to use the momentum to park on the side of the road causing a unexpected break down. The vehicle won't start. This again seems electrical and the dealership want to charge for this. The vehicle is damaged since the manufacture and huge safety issue. Please urge to get a recall for all this items since it seems immersive expensive and unsafe to have to repair all this issues.

After 5 years and 2 months of ownership of this vehicle, at ~52,000 miles it began to develop a shudder in the driveline, that I originally ascribed to an imbalanced rear wheel. After checking the rear wheels for balance, that cause was ruled out. I took the vehicle back to the GMC dealer where I had purchased it new. They claimed that the cause of the problem was a defective transmission fluid that somehow became contaminated with water. They offered to flush the entire transmission and install new 100% synthetic transmission fluid for a cost of $770. When I complained about a vehicle with 52,000 miles developing transmission problems the dealer consulted with GMC, and then agreed to flush and replace the allegedly defective fluid without cost. Upon further investigation, it appears as though the origin of the issue is not due to the nature of the fluid, but rather the use of an undersized torque convertor in this 8-speed transmission, which began in the 2017 model year. The smaller size and inadequacy of this torque convertor design is the root cause of this shudder, which not only has presented itself in the 2017 GMC, but also in corresponding GMC/Chevrolet models using the same transmission. The danger of a transmission failure can have catastrophic safety consequences for the driver, passengers as well as the motoring public, not to mention a very large transmission replacement charge for the owner. There is currently a Class Action lawsuit in the State of California for this notorious "Chevy Shake."

The contact owns a 2017 GMC Canyon. The contact stated while driving 35 MPH, the vehicle failed to respond when the accelerator pedal was depressed; instead the vehicle would jerk forward. The contact stated that there was no warning light illuminated. The contact had driven the vehicle to a local dealer, who diagnosed that the transmission needed to be replaced. The vehicle was repaired at the owner's expense. The manufacturer had been informed by the dealer of the failure. The failure mileage was approximately 64,000.

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.

TRANSMISSION EXPERIENCES TORQUE CONVERTOR SHUDDER. WITH VERY HARD SHIFTS AT 5 AND 18 MPH. DEALER COMPLIED WITH BULLETIN 18-NA-355. HAD IMPROVEMENT IN SHIFT FOR A WHILE. THEN HARD SHIFT RETURN AT 5 AND 18 MPH. DURING DECELERATIONS THERE WOULD BE A SHUDDER. WHEN USING CRUISE CONTROL WHEN REDUCING SPEED TRANSMISSION WOULD SHUDDER. RETURN TO DEALER, WHEN OIL PAN WAS REMOVED FOUND ALUMINUM CHIPS AND ONE METAL CHIP. DEALER REPLACE WITH REMANUFACTURED TRANSMISSION. DROVE VEHICLE HOME. THEN WENT OUT AND DROVE THE VEHICLE UPON EXITING DRIVE WAY EXPERIENCE TORQUE CONVERTOR SLIPPAGE AT AROUND 12 MPH WITH ENGINE RPM GOING FROM 2000 TO 4000. CONTINUED TO DRIVE VEHICLE ONCE TORQUE CONVERTOR REENGAGED. CONTINUED DRIVING MADE COUPLE OF SHORT TRIPS IN TRAFFIC CONTINUE TO EXPERIENCE BANGING IN DRIVE TRAIN. I BELIEVE THIS VEHICLE PUTS MY SAFETY AT RISK
