My new Prius C started with headlights not working and the Check Headlight System light goes on, along with the warning sign. It is dangerous to drive at night with the headlights suddenly not working. I have been taking it to Toyota dealership multiple times, however it always starts working when I turn the headlights off and on at the dealership, so they don't see the problem. It is very annoying to have this problem with a Toyota car since they are known for their quality of cars and it seems that this has been a common problem with Toyota Prius and should be a recall issue.
