Loose Upper Ball Joint - Wheel detachment scare!

I bought a Mahindra Scorpio-N 4x4 Z8L from them in August 2024, trading in my faulty Scorpio-N 4x4 Z8 ( which went back to the dealership 16 times). On the first drive home, I noticed that there was a knocking noise on the front suspension, I test-drove the car on the Highway and took it back the next day. I received an email from the DP that explained it was a Tie-Rod end (this has obviously proven to be a misconception). The worksheet I only received last week showed it to be an Upper Ball Joint - The difference is that if the UBJ bolt loosened it would mean the whole wheel detaches. There have been numerous reports on this happening. I am not sure how this was let through the PDI (Pre-Delivery Inspection), as it should have been a known issue.
