Alternator/generator/regulator problems of the 2003 Infiniti I35

While driving down the street, the vehicle shut completely off. I could not steer or anything. It was not the battery, alternator. It just stop right in the middle of the street; which is very dangerous. I called the used car dealer whom had just sold me the vehicle less than 6 month whom had the vehicle towed. They indicated they fixed one of the sensor & there was electrical issues. It drove for about a year, now it is continuously doing the same thing, shutting down while driving. The check engine light will come on & slip/ tcs. The vehicle have endangered my life about 5 different time for the same reason with my grandchildren in the car. I know several people that are going thru the same thing. The dealer did not notify me of the recall on my vehicle. I had to find it out when trying to trade my vehicle.
