Buyer beware!!

My KIGER is months old. Following are the problems : i. Poor mileage with an average of 8.5 km/l. ii. It's a struggle to wear seat belts in the front. iii. The AC pump broke down in 5 months, and spares have not been available for the past 15 days. iv. The entire chassis creaks like a sheet metal beam being pressed on releasing the brakes ( I have an Auto gear car).
