Hyundai Motor India — Warranty issue bij

My creta HR51BV732 IS in warranty period. After 05 days of 50000km service. the gear of the car got stuck and some fluid below the car got leaked. The dealer gave me a bill of Rs. 27500/-. If the Car is in warranty period then, why should I have to Pay. I am agree that Clutch is not covered in warranty, but what about other parts. why liquid leaked from the car. I need refund of that amount from Hundai motors. Also my battery got discharged. please let me know why u say that 03 years warranty i[censored] did not covered anything.
