Possible factory fault on Ford Everest 3.2L Ltd 2016 Model

I am extremely disappointed with the customer service I have received from Ford. I have reported a power loss issue on my Ford Everest 3.2L Ltd 2016 model which randomly loses power on long distance driving. I have experience the issue several time whilst driving between JHB and DBN. Extremely frustrating and unsafe when traveling with 3 kids and wife on the car especially driving up the Van Reenens Pass. I have sent the car to 2 deleaships as referred by Ford SA without any resolution or possible solution to the problem. I am paying a huge installment to drive an unreliable car. To date I fear driving it long distance because of this issue but Ford still expect payment for such. Lack of solution or support has led me to believe that there is a factory fault on the 3.2L Ltd edition 2016 model. The car is still under warranty but support is just poor.
