“I'm the owner of a newly bought (6/5/2020 purchased date) 2020 Gmc Canyon. I took my truck into the dealership and complained that I have experienced transmission issues when downshifting or accelerating. My most common issue is 'shuddering' when the truck accelerates and sudden 'jerking' when downshifting gears when driving up an incline or even coming to a complete stop. The dealership said they haven't had any problems with the 2020 canyons and unless it reads a 'code' there's nothing they can do. Gm said tell the customer to drive it and we will call if we get any further information. …”
NHTSA complaint #11362569, filed 2020-10, 13,000 miles“When rolling to stop signs or red lights, the vehicle occasionally fails to downshift properly and will attempt to continue pushing the vehicle when trying to stop. On multiple occasions, the vehicle acts as if it cannot be stopped due to the transmission failing to downshift. One must aggressively apply the brakes to get the vehicle to come to a stop. Unable to have the vehicle checked out at a local dealer, due to being backed up for weeks when trying to have it looked at. No visual indication/warning is given when this happens. …”
