Hyundai Motor India — manufacturing part quality issue in my xcent ac cooling coil (non moving part) within 3 year period

Address:

Jaipur, Rajasthan, 302028

My car ac cooling coil damaged within 3 years. This a non moving part & manufacturing quality of this part is very poor as most of the hyndai i10 & xcent customers are facing this problem in there cars within 50000km running. I have get my ac checked from authorized deeler. He is not even clear about the problem & asking for labor charges approx 3500 just to diagnose the problem. Part change will further add an additional cost of rs 3500~4000 extra.
Pls help me to get this poor quality part replaced as manufacturing quality issue & a burden of approx. Cost rs 8000/- in non moving part within 45000 km & 3 years running is disappointing.
