Starting problem in Brand New Baleno

Starting problem in Brand New Baleno I bought my new Baleno Sigma model just 2 months back. Appearance wise vehicle is amazing. However, body of the vehicle is kept very light weight. Even the slightest bump on the road may lift the vehicle. There is always some kind of a noise from the rear side. Well, I am facing a peculiar problem that I would like to share with. My new Baleno car is not starting up once stopped/parked. And this has happened to me 3 times by now on different occasions. And I have faced lot of problem due to this. Vehicle is jammed in the middle of the road; no function of car is working, thereby becoming a cause to create a traffic jam. While staring, Vehicle is not giving any kind of response in a effort to start the ignition. On first glance, it seems the car battery is down, after trying for 4-6 minute, the self of the car starts taking an idle rounds but still vehicle is not picking the ignition. It seems as there is short supply of fuel to the engine or may be fuel pump is not pumping sufficient petrol to the engine. After continuous efforts to start the vehicle for 10-15 minutes, finally the engine gets started and I was relieved from the staring eyes of the passer by. I fail to understand why this is happening to a car which is brand new. After discussion with the Nexa staff thru I bought the vehicle, I took the car to Maruti Suzuki Workshop to get the problem sorted out. Somehow, the vehicle did not show any inappropriate functioning in front of the Mechanics. As this usually happens, things do not show any abnormality in front of the repairing person. I insisted that they should check the vehicle with some advance tools like EBD etc. But, I was returned saying that they did not see any irregularity and the vehicle is functioning normal. Now, the point is, how should I convince Maruti staff that I am facing problem due to this unique kind of problem. It is such a problem, which may happen anywhere anytime, beyond my control. And Maruti staff will not believe me until it takes place in front of them. What should I do??
