2010 nissan altima hybrid suddenly lost all power (both electric and gasoline generated) while moving in traffic. i had to cut across 2 lanes through heavy traffic (while coasting) to get to the curb. after waiting and shutting the car down, i was able to restart it. i took it to the local dealer, which simply said the car "showed no codes" and, therefore, was unable to diagnose the problem or make repairs. i consider this a major safety problem, as i now question whether the vehicle can be safely operated or taken on any long trips. *tr
