Maruti Suzuki India — Maruti suzuki wagon r

Address:

Ahmedabad, Gujarat, 382340

Respected senior authorities,
My father had bought maruti's wagon_r in nov'14 but due to his rare use of car, he asked me for its regular use. When i drove it, i found plenty of manufacturing or installation faults which is as below.

1) visibility issue in windshield (Front glass) and side glass in rainy days when a. C. Is on

2) theft alarm/sensor not turning off

3) music system has 4 (2front + 2 back) speakers out of which 2back speakers are not working

I visited plenty of service station mainly to turn off the alarm, but none them able to do that, some of them have suggested to consult any technician outside maruti for paid services.

Kindly suggest how to deal with these issues, waiting for your favourable response.

Thanks & regards
Alok y. Rajput
