Ford Tourneo Custom- new but problems…

Hi, since yesterday I own a Ford Tourneo Custom Limited L1, 6speed manual transmission, 1 year old. But there are some problems, who can help?? -Start Stop system does not work, the engine stays on no matter how long I stand at the traffic light.. -When I refuel the soup overrun (is either on me, the car or the pump) -When I switch, as the onboard computer suggests, the car drives extremely undertouring (if you call it so when it vibrates?) Well, someone has vllt Kiki.
