I’m dealing with this for the second time on a 2014 Fusion. I get the following
messages: “Battery Saver Audio Off” and “Battery Saver Start Engine or Turn
Ignition Off”. It seems to happen when I use my phone and Bluetooth it through the
radio. At the time I didn’t know what I was smelling, but I was driving home and
smelled sulfur. The next day I was driving and smelled sulfur and heard bubbling
when I was stopped at a red light. I had no idea, my battery exploded on my drive
home. Well, I replaced the battery and all seemed fine for about a year and a half
and it has happened again. I am having the charging system evaluated. Please
post any updates!
