Intermittent battery failure points to power drain

Intermittent battery failure points to power drain

Dear Car Talk:

Our 2015 Ford Edge with 14,000 miles and purchased new in January 2016 has had the battery go dead four times. The first time, Ford service sent a technician to jump-start the car. The second time, the car was towed to Ford and the battery was replaced. The third time, the car was towed and the battery replaced again. And the fourth time, Ford kept it for five days and found no problem with the battery. Usually, but not always, the battery goes dead when the car sits for three to four days. We are retired, so the car is not driven daily. What could be the cause of the battery going dead? — Cheryl

It sounds like a good, old-fashioned power drain,...
