Tata Motors — Tata Nexon Dark Edition

We have purchased a Nexon Dark edition and got delivery on 2nd April,
After 4-5 days while driving in a temple premises suddenly the right excel and wheel got separated from the hub, and lost control and it stopped by dash on grade separator.
When We observed it we found that axels is separated and this was happen due to poor Quality Check of TATA.
So now the dealer is asking that we have to claim it in the insurance,
but why we use our insurance when it is clearly visible that it’s a TATA and its dealers mistake.
car has not driven more than hundred km also.
So please help us or Will log a legal complaint against TATA and its dealership.
