I went into purchasing dealer for first oil change at 5100 miles, they flashed computer and loaded update Hyundai campaign 953 product improvement. About 50 miles after the recall was performed my car went into limp mode and is barely driveable. Car was also hesitating, and bucking a bit. Took it back to dealer they stated the code didn't apply to my car and flashed it again. It again went into limp mode after 50 miles or so. The recall is supposed to place the vehicle in limp mode due to rod bearing wear. My car has 5,400 miles on it and it now at a different dealer.

Purchased new 2018 Sonata sel model in California. While driving, the transmission starts to hard downshift when the brake is applied. I found out that this hard downshifting and jolting/thumping of engine and transmission only occurs when coming to a stop at speeds between 10 to 15mph. It can be described as follows, after the brake pedal has been gently applied and lightly released but then the car itself applied its brake again. It terrifies the driver's driving conditions, mentally and physically.
