Bought X3 a month ago . After driving 3300 km shown deivetrain error (engine error) with large ratteling noise from engine . Speed reduced to 40 from 120 in spurt of a moment imbalancing the car. All this happened in remote area of punjab BMW roas side assistace very poor. Made to travel next 400km in non maintaied scorpio with charging port out of order , no gps assistance, driver not knowing the route and driver in no way associated with BMW RSA. Refused to provide loan vehicle claiming that this is not their policy. So very very poor afer sale service . And manufacturing defected car.
