I just downloaded this Dr Prius app to find out the status of my 2009 Prius with 190k on original hybrid battery in Los Angeles all its life. I know hot weather states can kill the hybrid sooner. It says it 53% life expectancy and #12 has issue. Can anyone explain the solution to fix the #12 problem. I'm guessing buying a used module and replaceng it. Do I need to worry about the 53% life expectancy? When does life expectancy get from 53% to below 40%? Is this a 20k or 50k or years 2-5 years left? Thanks, Kap. SM-A526U ?
