Mahindra And Mahindra — Frequently coming faults in my xuv300.

I have some questions and their answers too but i want to know your approach towards your so called valuable customer? That,
1. why a middle class person go ahead to buy a brand new car with a heavy financial liability of lakhs of rupees?
My Ans: He/She drops his/her old car and buy a brand new car that 1st...he/she can drive a new vehicle without any bad or harassing driving experience.
2nd... 0 (zero) or minimal maintenance at least first 3-4 years, except required servicing as per the company's recommendation.
3rd...Luxury feel.
There may be other reasons too, which very person to person, but for me, it is just about a good driving experience which mainly include the high expectation of quite a less or no chance of breakdown in the vehicle while driving.
Now i will come to the next step.
I purchased a new XUV300, W6 Diesel in Jan2021 from Mighty Autowheels, Bahadrabad, Haridwar (Uttarakhand).
One day i was on the way to destination with my wife and two children (6 yr and 8 months) with required luggage as per family size. I was near MUSSOORRIE (Uttarakhand), Suddenly the engine temperature indicator shows HIGH ENGINE TEMPERATURE with a red light alert and beep sound. I stopped the car and called Mahindra RSA, they came and dropped the car to the nearest service centre at DEHRADUN (DDPM Dehradun). They investigated the car (i dont know what they investigate), according to them they found nothing wrong and handed over the car to me after some days. ok then, but the other side at which you have to take a kind view, Sir.
AT the above event, the odometer of my car shows approx..1500 km. ok from the point of event, i had the onward journey about 200 km and due to some urgent office work i hired the taxi sent by RSA (free for 50 km) for my destination and paid him Rs. 5500 from my pocket and also waited 2 hrs near the road side with my family. what do you think about it????? what a great driving experience a new car gave me????? and also an extra burden of Rs. 2000 was imposed on my pocket when i go to take the delivery of the car by travelling 200 km on hilly road. But i thought it has happened once, ok, let it be. But i was wrong, , , wrong, , , quite wrong...
I was at my destination., same place, , around 200 km from the nearest service centre DDPM Dehradun. I saw ENGINE OIL DROPS under my car, IT was very heartbreaking, but i first thought that it may be my fault, may be oil chamber hit by stone somewhere, but when i thoroughly checked i found that ENGINE OIL leaking from somewhere else... HOW HARASSING IT IS for a customer, the car odometer is just at 3200 km, , and it is the second time a crane/tow machine came and lift the car to the service centre... why...????? the same harrasement againg, , , why sir???? Now i left all my urgent works unattended and came to dehradun with my vehicle to get the repair done in front of me, , but it hardly matter???? why?? Would you please explain me the answer? sir i have lost my faith in this car.. i was very exciting to buy an Indian make car, , and i did so too.. but you gave me the worst experience and mental trauma that when will i have to tow this car to the service centre next time, , , ?? it may me next 1500 kmm ? it may be next one month???? when???? what reviews i should give to my friends now??? pls answer and if you actually have concern in your customer pls show the loyalty to me what you are known for.
