In My experience Few TATA Products Also is the same.
1) Tata indica - Purchased in 2012. Owner driving. ver minimal use. 2015 clocks 50000KM. All service done by TATA dealer Only. Just said the Fuel Injection pump need major service - will cost Rs,7000/-.
Our Own, Lot used "AMBASSADOR" Fuel injection pump is not yet failed after purchased in 1973.
Found out from FIP maker delphy - "Because of lowest quote for TATA" the quality of the parts inside the pump is Low quality. TATA want to give us a low cost car also giving the low quality car.
2) IOB ( Indian Over seas Bank) ATM all maintenance contract is with TCL, not a single machine is working properly. If you call them, it will be attended as they wish. The service is not for customers. Un confirmed news is Lot money is being swindled by top brass in IOB for such contract to be awarded to TCL.
3) TATA SKY the charges are very high & told - equipment failure happens often and costing lot - comparing to other providers.
It is time For TATA to think about people confident first.
otherwise god help TATA. more
