    I recently got a 2010 Prius. Everything works fine until I realized it dies every few days and needs a jump start. I have installed a new battery and the same problem keeps happening. I will depress the brake pedal and see the green light with the power button and when I go to press it the car does not start and dies.

    any help would be appreciated!

    Check the dome lights, the one in the trunk also.
    Since you've replaced the battery, (did you charge it?) it would appear you have
    a drain.

    Loose connection at the battery posts or negative cable on the chassis from negative battery post.
