Ford India - Cheating Wali Feeling

I bought Ford Endeavour over Toyota Fortuner over its features but all are sham if reliability is not there. My Car's sunroof got cracked without any external impact, even with the full CCTV footage of the car when the incident happened Ford has no explanation of why did it happen. They want me to use insurance to get it repaired. As per Ford India, they have checked their records and no other vehicle has reported such issue so there is no issue in the sunroof, whereas Ford Global has a different data which this report shows (https://www.consumerreports.org/car-safety/exploding-sunroof-danger-overhead/). I am surprised what will happen to car owners who don't have proofs regarding any quality issue in the car and want the Ford team to hear their case. They simply don't want to own up to the issue. thankfully the car was parked and no one was inside the vehicle when the incident happened, what if my family would have been sitting inside the car and that roof would have cracked. This could be such a risk to human life. Even after multiple follow-ups with Ford management, I have not received a satisfactory answer on the reason for this, even if I get the car repair under insurance (which ideally should be covered under warranty) what is the guarantee that this will not happen again. None of the senior management is approachable who can assist and provide a satisfactory solution to the customer. I want to ensure that every future buyer of Ford knows what they are getting into, and what kind of treatment they will expect when they buy Ford Cars.
