We have had intermittent electrical issues for several years. The car suddenly looses all electrical power. The battery is completely depleted. Once jump started the car will then operate properly. I have had the alternator replaced once and the car has been checked by mechanics several times, no one can find the problem. We often times smell a burnt plastic odor just before the failures. This failure has happened dozens of time over the past 4 years, even during warranty. Ford did nothing for us.
