I cant have this happening to my wife with my kids in the car, it was that or Sell the car which might still happen if the CEM replacement does not work, i did get all codes read and there were alot fingers crossed as i actually like this car.

This isn't a common issue , I'm working on them on a daily basis ,Yours is the first I have heard of. It could be a poor solder connection or a component failure in the cem but that could be difficult to find . A new CEM should cure it. .
