spares to be strengthen like carrier and inter cooler

I have purchased new GRAND-I10 SPORTZ CRDI Engine on 30th Dec, 2013.  I travelled 978 km happily.  After 55 days, i have given my vehicle for servicing at your authorised show room.  After teflon coating  and anti rust coating, they observed that carrier and inter cooler has damaged.  I surpirsed that there is no accident occured, i have not felt any jerks during my travel, how those parts are damaged.  During 2 months i enjoed very much with this vehicle.  Why the comapny has produced the delicate parts for this nice vehicle.  For replace those parts minimum time taken your company is 15 days and unexpected expenditure is Rs. 25000/-   My sincere advise to HYUNDAI company, produce strong parts which is likely to be damaged  for indian roads.  I never expected this type of experience with great  HYUNDAI company. My friends and family members are using so many vehicle from HYUNDAI company.  Kindly take my feed back in positive manner.  

Thanking you
