Mahindra And Mahindra — tuv 300 t6

I feel that i have made some kind of mistake by purchasing your vehicle. This vehicle hp09a 4667, was purchased from gurgaon and registered in hp. From the very beginning some or other thing keeps happening and we have to visit your service station.
1. Vehicle is with sri durga automobile rama rd, delhi since 2, 6, 18 morning as engine was making noise and sometimes suddenly the pick up goes very low and then it will get corrected itself. Till today, pankaj sharma is not able to give any answer.

2, this vehicle was taken to this workshop about 1 month ago with same problem and were told that testing material will come in 10 days and then they will call, no call came. This problem is from the beginning when we bought it.

3. Steering wheel problem happened in dec, 2017, rectified at shimla, after i was able to bring this vehicle to shimla after much difficulty - appears manufacturing defect
4. Within 6 months of purchase, in 2016, break oil finished - again some manufacturing defect.

I want to know if mahindra will be able to rectify these manufacturing defects once for all or we have to suffer
