My 2006 Buick Lucerne engines stops randomly. As I am traveling down the road the engine suddenly cut off and there is a loss of all power steering and brakes. All electrical components blacks out and when it stops you can not crank it. After waiting different amounts of time you can crank it up and continues until the next mysterious outage . This is my wife car and I do not allow her to drive it. I do not take it on any winding roads. I went to the dealership where I purchased and was told if there is no check engine light then no codes will be set to find the problem. I have carried it to three other shops to no avail. One mechanical was driving it around town and it happen on a roundabout. He said he had to struggle with all his might to get though it before he could stop. I do not know what to do and hopefully nothing dreadful will happen, like gm cares.
