Within 48hrs, the car was taken for a short drive within 5km vicinity, had a loud crackling noise again . When stopped and found by near by local help on highway, it was found that there were no screws plated and the clutch discs have come closer to the wheel, which can kill anyone as it can break the wheel!

When I called the myTVS service person, no proper response. Never give the car to them and they are money suckers without any knowledge of what they must do.
