Problematic new Vento Highline MT Petrol.

In span of 25 days of delivery,car taken twice to workshop.1st..for occasional sharp sound from engine(their service advisor also heard it).It was checked and all ok given.The loose front bumper also fixed on 14/10.However on 15/10,whilst on the road,sudden collapse of ac/window functions/rear sensors etc.Fortunately engine did not collapse so drove to workshop.Said woud check reason and inform me on 17th.WHAT NEW CAR?Pricey but No reliability.Pathetic atitude of Tornado dealers and Volkswagen .I do not recommend-go for other car brands.
