When accelerating it will create a hard shift or not fully engage into 2nd or 3rd gear. Also, when auto stop/start engages it jolts the car when stopped.
When parking the car in the parking lot, I turned the car off with my foot on the brake, didn't notice I had not put car in park and when I took my foot off the brake it rolled backwards. I quickly put my foot on the brake and put the car in park. Thankfully I was in an area where no one was behind me. I was shocked that the transmission disengages when the engine is turned off. I was told by the dealer that this is a normal. After looking at recalls on previous models, I saw a recall for a similar problem on some 2015-2017 Chevrolet vehicles. When it first happened I thought I imagined it. So I tried it yesterday in the driveway and sure enough if the car isn't in park and you turn the engine off the car will roll.
