Hyundai Motor India — Hyundai i20 Asta o 1.2 cvt

I purchased vehicle in nov 2019. Car is in good condition as due to covid, there has been less movement. I did my third servicing this month . Yesterday I met a clutch hardening while driving in high way. It’s not acceptable for maker like hyundai have failure of clutch cylinder in only 6800 kms running. I don’t want to write much . I want OM to decide what’s to be done in this condition.
