    I agree with Bisco....if we have any electrical issue in these hybrids, the first, and easiest, thing to check is the health of the 12-volt battery.
    If you don't have a good battery tester, auto parts stores have them you can borrow (or they'll test it for you.) You don't just want to check the current charge in there, it has a % of health and anything below 70% should be cause to replace it ASAP.
