Car Will Not Start problems of the 2013 Buick Enclave

The vehicle failed to start on 12/1/14. I called the dealership in san luis obispo, California, and they towed it in. The battery was fine and they told my wife that they could not find anything wrong with it and that it was good to go and they gave it back to her on 12/2/14. On 12/4/14 my wife and two young children were driving and about to get on the freeway 180 miles away ion san jose, California, when the car stalled and froze up while going 40 mph. Power steering did not work. She pulled over to the side of the road and the car shut off. Thank heavens she was not on the freeway. The car was towed to the dealership in san jose. Today they told her that they could not find anything wrong with the car but the computer did show an electrical failure. We called gm and told them the problem and they will speak with dealership tomorrow. This is the same problem I believe with the 20014 model where, I read on the internet, the chassis electronic module may be internally contaminated, resulting in an electrical short. It states that if the module experiences an electrical short, the vehicle could stall, increasing the risk of a crash. This is exactly what is happening here. The 2013 model needs to be recalled as well before somebody dies.
