Skoda India — skoda rapid diesel injector full defect

My skoda rapid 3rd injector also failed. Feel cheated as not replaced even though it's manufacturing defect. Car lying at dealer.
My skoda rapid diesel car is 2012 model. It is shocking to note that it had got frequent injector issues right after the delivery that all three injectors failed. First one got damaged in 2015, next in 2018 and now in 2019.

The car is now under service who informed that i have to spent rs.25k for replacement of the injector. Earlier these were replaced on goodwill warranty. Now it is forcefully passed on to customer for the manufacturer's defect. All other car companies usually recall the cars for free replacement of damaged parts.

But it is worst experience that for manufacturing defect of parts customer is forced to pay for company fault which is not accepted. I wish to inform that this has to be replaced free of cost as this occurs frequently every year due to original injectors were faultly designed and low quality parts were installed in my car. My car is prompt serviced at every year at your authorised centres, still i have to bear the cost of damaged parts. This is not on account of wear n tear or my fault, instead manufacturing defect. I had placed lot of trust on skoda quality but this bitter experiences is affecting customer confidence.
