Junk of Iron on four wheels

We bought the vehicle from Neo Nissan & just within 3 days time vehicle was giving problem & on a complaint we need to visit the showroom. After that, they confirmed that there is some problem & has rectified. But in 15 days time again said problem arise. Now again we need to go back to the showroom for rectification. After spending 17 lac why we take such junk of iron on four wheels. I recommend don't but Nissan Terrano at all. The Neo Nissan people does not have the capacity to even explain the problems. Further, they are unable to explain the navigation system & use of touch screen panel. Nissan people are least bothered about the problem they just forward the complaint to Dealer & dealers are helpless. No system in Nissan Company & I think they should close their operations in India. They are just making fool of us by selling junk of iron called / advertised ?Nissan Tarreno?
