Tata Motors — Mileage and warranty

I took my altroz xm+ to showroom for second free service at sixth month. Car was producing noise during steer. Two anti roll bar link were replaced and Rs. 1900.00 was charged. Why these parts are not covered in warranty?

After servicing, mileage was drastically dropped at 8kmpl. Now it is around 11 kmpl. These figures does not match with claimed mileage of 19 kmpl.

Please look into this and revert back
