Sync calls back people I have hung up from - enough to be annoying - my blue tooth in my 2012 Explorer will call the last person I spoke with back while I am in my car within 20 to 30 seconds after I hang up with them. It does it even if I have pushed the "end call" button on my steering wheel or on my Sync screen. Anyone else experiencing this? I've reported it multiple times to my dealer when it's been in for servicing and so far no luck figuring it out after a year and a half....
