2003 INFINITI I35 Steering Problems

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...
