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. This is a serious problem. I was driving the vehicle and because of the sudden jerking and transmission & or engine issues with the vehicle the rpms reved up to over 4500 rpms and I was stuck out in the middle of a lane and could not go anywhere. I had cars avoiding me so that way they would not hit me head on or on the side of my truck. This is a serious and fatal accident waiting to happen and the issue is GM knows about it because it happened with their 2015- 2019 Colorado and cannon series. Despite many complaints and numerous lawsuits about these serious issues, there are currently no ongoing investigations regarding transmission and engine defects for these vehicles within GM for the 2020 canon. I have paid almost $50,000 for a vehicle that should have a lemon law put on it because GM knows they are producing bad transmission/engines and not doing anything about it. I asked GM corporate and the local dealership what am I supposed to do when I'm in another situation where the vehicle does not want to get in gear and is shaking and shuttering and jerking and revving up the rpms and the next time. I said I probably wouldn't be so lucky as to having people avoid me and then me and my daughter wind up in a head on collision and we don't make it out alive.
