Check the carbon deposit on the electronic throttle body. It should be solved after cleaning the carbon deposit. For vehicles driving in urban areas for a long time, it is recommended to clean the electronic throttle body every 15000 km due to the long-term low-speed driving of vehicles. If the vibration is caused by carbon deposition, the owner needs to bear the cost. If the vibration is caused by a faulty or damaged component, the owner of the vehicle can go to the store for free maintenance during the warranty period and ask for replacement of the faulty component.
