മികവുറ്റ car.. but many problems ഹെക്സ discomfort vechile ൽ

I buyed hexa in november . car interior and outer body look is very good but hexa doesn't have a initial pickup and in 2nd gear pickup is very worst comparing to all other brand cars and in hexa there is a problem in major issue in gear from 2nd gear to top gear when we apply gear and press acceletor some noise is coming in front right side when i took to showroom to say the problem they are saying its common in hexa vechile and y the hell they didnt say while when we book a car and very worst service in concorde motors very careless in service when i said this problem they are saying its common and we didnt get still any upadation about this problem from tata side ..i suggest not to buy this hexa instead of buying this hexa buy other vechile its better then hexa.....and that noise sound is very much irritation while driving and no comfort in driving worst in pickup ..
