I purchased a vista from kulathunkal motors trivandrum, kerala on may 2010. From the time of delivery, heavy black smoke is noted and reported to the service center mohandas motors, trivandrum. They are trying to resolve it before the first service itself. They cannot do it till now. One engineer from company checked my car and my complaint is not resolved. I have to replace clutch assembly before 3000 kms and steering box assembly and meter cluster before 16000 kms. Now the Fuel injection pump(the heart of a diesel car), turbo charger, clutch, steering column, cluster switch etc needs replacement. The service center blames at the company at every time for the delay in getting spare parts. But the spares are available with spare parts dealers and they are not supplying spares for warranty replacement. I wrote many emails to company and the service center and i am tired. Now the vehicle emits black smoke heavily. I am totally disappointed and helpless. I have to spend more than one month time in workshop till today for rectifying the complaints with my car. Please advise me
