Mahindra And Mahindra — Xuv 500 w11 engine issue

I had purchased my xuv 500 w11 in September 2020 since then I am facing a problem of engine indicator and veg not picking up acceleration. Earlier I was told to run the vehicle over 60km/hr for long distance. Now m posted in Bhutan and this being a hilly area I can't run it for long distance. This problem had occured twice in 8 months and no service station being here I had to send it to India costing me 20 thousand each time. My trust from Mahindra is losing and I feel I have been handed over a faulty vehicle. Since it's my veh only which is facing this problem. I am an army officer and I invested 18 lacs but my trust is finished. This time there was no indicator and the vehicle has lost power and acceleration please get me a solution to it. Not accepted.
