I just had the battery replaced on my 15... I have had the car 13 months 20,741miles.. I got an alert on my phone from the Lincoln mobile app.. did not think much of it for about a week.... that's when the car started to turn over slowly.. Went to the dealer and they changed out the battery.. they said that the system was ok .. It was the battery.. I have been driving for 40 years never had a bad battery...after reading some of these post .. I think Ford should find a new battery supplier
