I would be on the dealer for this one. The car is too new to have this kind of problem. This has to be some part of the front suspension not moving anymore. If the car was mine I would remove the sway bar first & test. Then seperate the upper and lower suspension componets to isolate what part of the suspension is stuck. In my opinion the dealer should be doing this as warrenty if the car has not been in an accident then this should not be happening. Good luck. John
