Maruti Suzuki India — ac compressor stopped working

Address:

Cochin villa, Near chalakudy, Railway statiom, 680307

Dear sir, i have been using maruti vehicles for past 2 decades, at first i used zen then 800 i was satisfied then i brought a new ertiga petrol. Just 50k km ac stopped working. Service center engineer told me to replace ac compressor. I m not happy with the quality of ertiga. I was expecting a smooth ride till at least 1lakh km. How can maruthi resolve my issue oor should i go for consumer protection.
Thank
You
