Maruti Suzuki — Is Maruthi Ertiga delivered to me is a defective one or the dealer is incompetent ?

Address:

Madurai, Tamil Nadu

This vehicle TN59 BA 666 is under Maruthi authorized care since day one and the issue of gear synchronizing is in the vehicle since purchase and four times the gear box has been opened and worked but still the issue repeats in the vehicle Bearing this issue we had given our vehicle for repair of the same on 23 Jan 2015 But still the work is not completed and service adviser says there is nil stock of the required spares to repair Please clarify whether Maruthi has delivered me a defective vehicle or the dealership is incompetent to address the issue and also let me know whether the spares of Maruthi products are in such a demand that a simple repair of the gearbox takes more than ten days to deliver but still not sorted out As We are upset with the vehicle I would like to gift the same to your dealer or to Maruthi as it looks like mere piece of iron and we cannot dedicate our self to the extreme level of bearing the maintenance issues Kind Note : The completed billing history of the vehicle is attached for reference.
