I have purchased a vehicle on jan-2016 from prithivi tvs showroom, now vehicle is completed 1500km, two free service completed. Last friday 12/8/16 we went to market and came back to home and stopped the vehicle without any problem, next day morning i have started the vehicle, its not getting start. This is happening third time, last time 21/7/16 for the same problem vehicle have been taken to showroom under breakdown, after analysis they have changed carburetor and the spark plug. I need the detail analysis on the problem and the corrective action from tvs.
