Honda — Radiator cooling fan motor - premature failure

I bought My HONDA CITY ZX brand new in July 2007 and I'm very happy with it's excellent performance having driven 1, 36, 000 km.
It's VIN no. is MAKGD852F7N372079 and Registration number TN 01 AD 6386.
I have been regularly maintaining it only at Honda Service Station - SUNDARAM HONDA, Chennai since i bought it and I am very satisfied with the quality of service there.

In April 2017, At around 1, 00, 000 km, the radiator fan motor was replaced with a brand new fan motor (Original Honda Spare part No.19030REAZ11) at a cost of Rs.12, 000/-.

Last week, I was disappointed when this fan motor failed (Original Honda Spare) after having covered just 36, 000 km in a period of just four years !!!
I raise this complaint of the poor quality of Original Honda Spare parts and request a discount on the new fan motor (costing a whopping Rs.12, 000/-) which had to be installed being a crucial part.

Thanking you.
