While driving my kids home from the school the vehicle stark jerking and kicking in the back while I was accelerating. Then the vehicle stopped shifting gears. I pulled to the side of the road turned off the car, turned it back on and it worked fine. I have this incident twice in two years. Secondly the paddle shift gear showed as disabled when I want to use manual gear. Checked the dashboard and there is no option saying enabled or disable peddle Shift gear. Thirdly the forward collision warning light is on on the dashboard. From time to Time the vehicle stops abruptly.
