Tata Motors — fuel leakage problem tata tiago and disappointed

Address:

Ludhiana, Punjab, 141010

I purchased tata tiago on april 2016, but i am not satisfied with its performance and facing problems like fuel leakage smell when i used to drive everytime from last 7 to 8 months. I sent it to tata motors to make it repair on 4th sep. If any mishappeing occur (Like fire due to oil leakage) then who's is responsible for this.

I just visited a tata motors, they said there is pipe leakage problem and they have to replace it soon. But they don't have part available with them right now and it's already a week now. Today i recived call for dada moters the part reached at workshop but then i visited then dada moters gm says sorry we recived wrong pipe, so we have already put again vqr then correct pipe will reach at tuesday. Then i demand i need vehicle today at any cost.
Then he says if you need car urgent then we will put m-seal for temporary basis and take your car back, then pipe will come at work shop we will make repair again.

At present, the car's parts is under guarantee under your 2 yrs guarantee policy from the date of purchase (Till apr 2018). But what if it again get faults after repairing? Then who will responsible for this?

On april 17, my car had proper checkup in your premises (Dada moters ludhiana) but they did not find any problem regarding fuel leakage at that time.. Tell me then what they did in complete checkup and it's six months now if any mishappeing occur then who would be responsible since for that loss. At that time also my car door is very tight and not open properly, still same problem not solved.
