While I was driving tonight my vehicle shut off in mid turn causing loss of power steering. Where this happened is a very busy intersection. I had to pull over and when I put the car in park and restarted it came on for a second then shut off again. Then was able to get it running again. I had my wife and 6 month old daughter in the car and this could have been a very different outcome. I have read many of complaints online about this same problem in these vehicles. I really feel that gm needs to take a serious look at this issue before something major happens.
