BMW India — Deficiency in servicing

Address: 600002

Website: bmw

I am owning bmw 320i since 2011. Frequent servicing is done so far, but the car is not fully fit. For a few hundred kilometres run, for some defect or other the car is under repairs need replacement. Run below 20, 000 kms spent early 25 - 30% of the cost. Latest april spent 2.25 lacs. Now smoke is coming. Servicing centre, chennai demanding rs.2.14. Who will pay every time 2 lacs plus. I am not satisfied with the servicing ability at chennai. Please advise what should i do.
