Tata Nano — tata nano xta clutch problem

Address:

411061

I own a tata nano, which i purchased with a strong 'make in india' or 'swadeshi' feeling.
But paying a premium price as good as 3.5l for tata nano xta (Auto gear) model left me nowhere, as the car stopped suddenly with a beep & an amt fault alert while driving on a ramp to my parking space.
The customer care till the vehicle went to the service station is great, but as i see a lot of complaints raised on the web regarding the auto clutch is a wonder to me. Also, the service manager asks me to come to the service station to discuss the matter as they are not going to replace it under warranty for a vehicle just 1.25 yrs old & running 5000 kms.
I paid the premium price of 3.5l for the xta model only to get rid of this 'clutch' subject, which is now not at all operated by me. Still, they ask me to pay for the same.
Question is, while the clutch is operated automatically, why the xta automation designed by tata is not at fault, which might have created the issue due to its malfunction?
Tata must answer the above question & replace the required parts, as the above issue is the responsibility of design of xta to engage or disengage the clutch correctly in an auto-gear vehicle.
