Consumer Description

Vehicle will jerk and shudder when accelerating and de-accelerating. Mostly between 15mph and 30mph. I’ve taken the vehicle back to the dealership and they didn’t find the issue. This prompted me to do some research online and found in one of many. There is a class action lawsuit for 2018-2019 Ascents. The 2020-2021 and 2022 models will follow suit as they have identical issues. I’m concerned the transmission will fail and I’ll have a lemon on my hands. The sudden loss of power to sometimes sudden acceleration by suddenly downshifting is a concern. The vehicle will often hesitate while it tries to figure out which gear it needs. This has been happening since day 1 of ownership.
