FORD FIESTA AC PROBLEM

I am having a Ford Fiesta 1.4 EXI. This car is aged about just 4 years and clocked 43000 kms. 

Strangely it has developed some problem in the Air Conditioning System which the Service Guys are not able to detect at CAPITAL FORD,Bhubaneswar, Orissa.

First I was informed that it has a leak in Cooling Coil which has to be replaced. On investigating for 2 days and replacing the cooling coil the Service engineer says that the compressor is having trouble which has to be replaced also.

I am surprised for a Ford Car having such major troubles in AC in just 4 years and 43000 kms. Whereas i have never faced any such issues in any other Car i Own. This accounts for major repairing charges which is not expected for a car of this age and brand. I would therefore request the FORD COMPANY to consider this as a manufacturing issue and repair the same.
