excellent designed car with pathetic performance

I purchased this tigor xz in june'17, purely because of its stunning look. Initially i was happy with its performance. But as it crossed 5 month and 5000 km problem started with battery followed by poor coolling. Yesterdy it was stalled completely at middle of the road. I appteciate tata emergency break down service. But this kind of poor car performance will ruined the future of a good designed car.
