At the time of driving about 100 speed car is full shivering like anything and driving seat glass is not working if it is down it wont go up and other side if it is up it is not coming down and in climbing up car goes automatic lift side and brakes is also not getting properly.
So many times i went to workshop and they cant fix it.
