2 times the engine stalled in the middle of an intersection due to hybrid system failure. A simple fuse for the hybrid system went out and turned off all power. The main issue is that this is a very dangerous design flaw. Other hybrid vehicles have a safety feature that when the hybrid system is not working the gasoline engine will still be in full operation. Everytime the engine light goes on it kills the whole car. I got stuck on an expressway and was put in a dangerous situation when this did not have to happen because they don't have to make the 2 motors completely dependent on each other. Having the gasoline engine continue to run and be able to power the car in a hybrid system failure will save someone's life. I am not sure why this is not a requirement by law to have this safety feature.
