Automatic Emergency Braking problems of the 2016 Kia Motor Optima

Vehicle went into emergency mode while in the highway system completely locked could not drive lost power and was forced to pull over and have vehicle towed, mechanic took a look indicated new alternator was required there for we purchased new alternator and new battery car turned on and same issue happened with in 20 minutes of test driving vehicle, this happened twice and could have cost our life’s! I am extremely disappointed and frustrated I have no means to fix the vehicle we used out saving to finally replace what we though was the issue but I’ve come across many same issues from other parties who experienced the same issue. The vehicle is paid off and we need assistance in fixing this issue it appears the engine or electrical issue at this point but I am scared to get on the road we have tried charging it back on but steering wheels locks up and dies a few minutes after please help.
