Transmission shifts hard and rough. Mainly shutters the entire car when the automatic trans downshifts from 3-2-1 gears. Very noticable from 2-1 gear. Will almost surge/jump the car from these two gears. This can be a hazard as if I was to stop fast it will jerk the entire car and almost lunges the car forward when doing so. This car was bought July 27th, 2019, with 2k miles on it. Took it into the dealer and of coarse they deny any issue as they would be out thousands of labor dollars if they were to fix 1 car. So it's too easy for them to pass off that it's fine.
