Steering Is Tight problems of the 2016 Dodge Journey

I had 2016 Dodge Journey bought from superstition Dodge in mesa arizona. The engine shuts off by itself while braking and one time while driving. When engine shuts off the car looses power steering and brakes. This could cause fetal accident and may be death. I contacted Dodge tempe arizona. I went to them after it happen first time and they said no error code and it could be a glitch!! then when it happen for second and third time and I was about to make an accident, I contacted them again and contacted Dodge company. They open a case # 29588743. And tempe Dodge took again for over a week and they were not able to find the root cause. They want to give me the car back and I am afraid about my family safety and people and cars in the street. I contacted Dodge again and the case manager name is venessa x40752. She said there nothing she can do and she wants to close the case. They do not care and they want to give the car back to me knowingly that the car could have an accident again if the engine shuts off and the car fail to brake and steer. What happen is when driving, sometimes "3 times" when brake "2 times" or when slowing while running "1 time" the engine shuts off and the ignition button still shows run and ac is still working on the battery. When engine shuts off no brakes so car keeps moving and steering is very hard to control because of loss of power. It is life threating and could cause death to pedestrians and or passengers. Please help, I do not want my family to get injured or die and I do not want people in the street to get injured or die.
