I am unknown of what system has failed but the issue is that while the car is in motion, it will completely shut off. All Electrical will disengage and there have been times where a pop up has come on my screen stating that air bags and seat belts are non functioning to get to a service station as soon as possible. It has happened multiple times while driving on a large highway. This is a severe safety issue and I am so thankful I have not suffered serious injuries due to a major accident. The vehicle is unsafe and I do not feel comfortable driving it with myself nor guest in the car.
