Often, but not always, mostly when turning left from a stop as at a traffic light the car will hesitate and lose power and speed. then i try to accelerate and the car surges forward too fast. i feel that i am going to stall in the intersection.
Vehicle quickly developed a "surge, sputtering, jerk" type action when coasting or maintaining speeds above 35mph. also when braking, there is good and predictable speed reduction until about 10mph when the transmissions seems to unlock and the car lunges forward since there is suddenly not enough brake pressure because the transmission has shifted for some reason. dealer has been able to replicate the issue but has no known fix. brand new car 1 month old and it runs like a brand new car should, until you get to maintaining cruising speeds. very disappointing to have this one issue with something that is otherwise a fantastic car.
