1) Tata initial price are low, but dealers take up price on service to great extend.
2) Lack of follow-ups and online help
3) Service stations are less compared to volume and lack of process orientation for servicing.
4) TATA is later driven by service/dealers and have no control once the product is sold.
5) Parts at service station are replaced without any proper justification and TATA to lack to question and follow-up on why the part was replaced.
6) Service station and Dealer lack technical and customer orientation(falls commitments)
7) Many times parts are not available during servicing which makes the service slow
8) Registration and service record in TATA(Siebel) database has incorrect data and name, in spite of rigorous follows
9) TATA company is good brand, but product is not reliable, rather no control on dealers and service stations.
10) I am filling to sell of my car. which I have serviced(as per the manual)/at every 5500KM. Currenly I have ran for 41000KM(2 and half year completion)
11) I always need to pay visit to service station after servicing is done as the problem has re-occurred or some problem noified is not rectified at service station.
Suggestion
1) TATA need better control and questioner on the parts that are replaced at service stations
2) More customer orientation and follow-ups
3) Tight process at service stations and at dealer level.
Important Update:-
I have sold my car:-)
