“I was driving down a 3 or 4 lanes, each way, road in orlando, florida at about 30 MPH when it died. No warning or sputter, just died. It has happened off an on since that time. Probably 10 or 12 times, as I am turning into my driveway, pulling up to a stop sign, or slowing to make a left turn in traffic. This is very dangerous when turning left and traffic headed toward you. The car dies instantly. It has always re-started so far. I now have 80,000 miles on the car, and I am afraid to drive on long trips. Try to stay no farther away than about 100 miles. …”
