Friday october 30 at 1 pm pacific coast time, my volt lost all power on the middle of the san mateo bridge. there was no shoulder and the car went from 70 miles an hour to a dead stop in about 100 ft. i had a "propulsion system failure" message on the display screen. i was nearly rear-ended by a semi, who in turn nearly turned over trying to swerve out of my lane. the semi nearly pushed another car into san francisco bay. this is a dangerous vehicle and the government should not allow it to be sold.
