Skoda India — Fuel injector failure my car rapid

My Skoda rapid diesel AT is just 42000km and have cool and engine signal on the run in highway, I stopped and towed the vehicle to Tafe access as it was not much far from there. They are saying it’s injector failure and I don’t think a injector fails at 42000km, of it does it s manufacturing fault and case for recall. I ran vehicles for 100000km but never had to change injectors at all.
