2020 GMC Canyon owner complaints

The wiring in most vehicles 2020 and newer are soy/ nut based product… which squirrels, rodents and other animals can’t resist and the wiring throughout the vehicle is being chewed this all makes all models all manufacturers… there is also problems with the 8 speed transmission that shutters and hard gear changing and the quick fix is to flush out and refill it with transmission fluid

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

The main issue is the transmission... It shudders. Now I have to change the oil every 10K miles on it, or it will start shuddering again. It first started when the truck had 50K or a little more miles in it. The issue was resolved, I thought... Then it did it again at 69K (Just out of the warranty). I called the dealership and they stated I had to pay if I wanted an oil change, and they could not do an oil flush even if I paid for it. So I said OK, I will take it to a mechanic, and I did and "fixed" the problem. I used the oil GM recommended and the shuddering stopped. BUT then, another 10K miles and it starts again. I have changed the oil a lot of times... It now has 128K miles in it, and this last time, I had to change the oil at 9k miles because of the shuddering... What will be next?

I am the owner of a 2020 canyon sle that was purchased in june of 2020. The vehicle has about 20,000 mile on it currently. I have been experiencing a "lag" on acceleration after coming to a stop. This feels like the transmission isn't down shifting all the way. At time when accelerating from a stop the truck will act as it is in a high gear then suddenly slam into a first gear. I have take my truck to jessup GMC in palm springs and they say the tech can not reproduce the problem. This sounds like the same issue the 2015-1019 models have in reference to bulletin: 18-na-355 dated august 2019

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. There is a current class action lawsuit for models up to 2019, but this needs to be extended to 2020 models as well, as multiple online forums discuss this issue being prevalent in newer models of the 8-speed transmission.
