[Resolved]  Tata Motors — tata nexon manufacturing defect

It hasn't been even 2 months since i bought my tata nexon xm petrol. And now I'm having
1. engine starting problem.
2. A very weird clanking noise from d front tyre side
3. And various body sounds.

Now are those manufacturing defects? If yes then can d car b replaced? The mechanic told me those issues are minor and present in every nexon.
If such is d case then why are they selling the car with such known defects fooling us the poor public.
Very very disappointed with tata motors.
