Mahindra Quanto — engine turbo complaint in regular intervals

Dear sir,
This is to inform that my vehicle ka18 p0145 is in karnataka agencies, chickmagalore district karnataka state from 04/08/2017 with turbo problems, and they have been trying to rectify turbo defects but now they are asking me to replace new one.
I purchased mahindra quanto on 1/12/2012 from india garage bangalore but the vehicle is giving lot of problems after 50000 kms and you can see the history of all problems and finding problems every time with turbo which was rectified in chrome motors, bangalore but again i am finding a problems and they are saying that to replace with new one.
According to my knowledge the quanto vehicle is failed because of these reasons which directly effects my time, energy and money and economical loss of my business. By having my vehicle many times i am travelling in taxi. Many of the multinational companies are replacing the vehicles of such defects are found so i request to replace the vehicle or give us loss of compensation immediately. Consider this for immediate action otherwise legal procedure will be taken.

With regards
