2008 Honda Civic Car shakes when crank up

After 200 miles on the new car. In a morning I cranked up the car and I felt a major jump on the front part of the car. Ever since then, whenever I crank up my car, I feel something is shaking in the front of the car. Today when I cranked up the car after coming from lunch, the car hesitated to start up. After that, when I started my car, the car shakes terribly for about 2 secs and comes back to normal. Any advise? It is a brand new car
Thanks
