Tata Motors — Faulty oil pump in new tata nexon

Dear sir/Madam,

I purchased my tata Nexon dark edition (top model, MP17CD3088) on 5th of July from tata motors, Rewa, M.P.
Today on 26th dec 2023, My car didn't start and mechnic checked and told me that oil pump need to be replaced,
Its a 6 month old prevmier car, how it can malfunction due to faulty part so easily

Plz register my complaint and let me know if any resolution possible.

Thanks
