On Oct 4th my 2016 MKX with 15,000 miles had a bad battery. Started the car with a jump and charging was 13.6volts.
Took to dealer and they installed new battery under warranty.
Today Oct 7th I receive text msg from the car that my battery was low at 3AM in the morning.
Nothing is left on, I reset my sync3 to factory defaults on the 4th and it still has something on that drains the battery.
I have read that some modules do not turn off that may be causing this as others have had similar problems in both Ford and Lincolns.
I will be dropping off at the dealer in the morning in hopes they have heard about this problem for awhile as I read many messages dating back to 2015 about the battery drains down over night.
As an additional note I was getting a msg about my headlights not function correctly a few times about a month ago.
I have the headlights that turn with the wheel.
Any info would be helpful.
