Engine Noise problems of the 2014 Kia Motor Sorento

On January 2014, I bought a kia Sorento, 2014. On the same day I notice a strange noise on the engine. I took the car back to medina auto in caguas, puerto rico (dealer) and they said that the noise was due to the gdi motor type. I took the car several times back the dealer, with the same feedback. "the noise is due to the gdi motor type". My wife too the car back to medina auto for it first oil change and I again ask to check the strange noise on the engine. . . They immediatelly said to her thatthe noise was becauce the engine type (gdi). They call my wife to pick the car as it was ready. I went with my wife to the dealer to pickup the car, becasue that noise was not right. When I get to the dealer, they told me the same thing. The noise is due to the gdi engine type. I request that before I turn the car on, a mech technician be with me and that he personally confirm that the noise was the gdi. Well this time they found that the engine block was bad and it had to be replaced. . . If it wasn't for me, that I push them to re-inspect the noise, my wife could it be driving the car and I wondering what could it happen to her. . After requesting the replacement of the unit with a new car and since I notified several times medina auto of the noise, the dealer refused to replace the car with a new unit and only offers to fix the engine. I am writing to you, because this is not the first time I am listening to this situation with the kia Sorento 2014. Any nosie for the kia in the engine is the gdi. . . What could it happen to my wife and kids if the engine stop running or crank while my wife was driving it? there is something not right with the kia Sorento 2014, and the dealers and service departments are failing in identify the situation that could potential can cause an accident. . . Every noise in the engine is the gdi for kia, the dealers and service departments. . . . .
