The car was imported directly from Japan. After about a month I have been noticing this jerk, it was not noticeable at the beginning, but feel it is more frequent and aggravating. The wheels get locked suddenly feels it may effect safety of the driver and the passengers as it may cause an accident. Talking to some experts in the country has reveled that this is a manufacturing defect and in all the cars of the same model. Since Nissan is a reputable and customer caring company, expect them to rectify this immediately.
