Hyundai Motor India — faulty abs unit (leaking internally)

Address:

Chennai, Tamil Nadu, 600017

I have been an owner of a Hyundai i20 1.2L ASTA with sunroof since 23.01.2014. Regn. No. TN 09 BV 4907. I have been very happy with the Hyundai cars being an owner of a Santro before too.
The hand brake light has been lighting up on the dashboard some 4/5 months back. The problem was attended to by a simple top up of oil (by the authorised service center). But the problem has cropped up again. On taking it to the service station... I have been informed that the car has a leaking ABS unit.
I am shocked that something like this has happened with such a critical component.
The service advisor tells me that it is most unusual and even the part is not normally available. As it involves such a critical component, I have asked for it to be changed immediately for which I was asked to pay an advance of 25000. (I have promptly done so as safety of me and my family is paramount) I have been informed today (after 2 days) that it will take some more time for the part to arrive.
I would like to take it up with the senior level regarding this fault. A defective ABS brake unit is unacceptable. This is my 5th car and the first time a problem like this has cropped up. I think Hyundai must accept that the original part is faulty and replace the part. I would like to take this up at all forums as some components in a car are expected to perform perfectly and not throw shocks like this.
I would like a revert at the earliest as I am scared to trust my Car now. Please note that when I bought the car, I bought the top end version as I wanted ABS and the max possible air bags as safety is very important for me. After paying a premium for what I thought was the safest option, I feel it is unfair that my car has a defective ABS unit. I would expect Hyundai to replace the part and refund my amount. I agreed to pay the advance as the service center would not even order the spare without a 25000Rs. advance. As mentioned...the brake unit is not something I can compromise on... so I paid immediately. However, I do not want it to look like I am accepting it.
