when in drive the car shakes like crazy what could it be only 300 miles on it. Also when shifting from park to drive theres a grinding noise what could that be, and has anyone ever notice that when the car is in drive on a hill and you roll back that the car shuts off. Need help cause Im seconding guess my decision on buying a new civic. all is appreciated

 

b/c your car is so new, i'd take it back to the dealer and replicate the issues with a tech in the car with you. good luck.

 

Yeah, as mundy says, drop the car off at the Honda dealership ASAP.
