IggyAZ Posted October 7, 2018 Report Share Posted October 7, 2018 My 2016 MKX battery has drain on it from some component onboard. On Oct 4th my MKX sounded funny and showed on the Nav screen that it was shutting down things to conserve power. Got it jump stated and to the dealer who replaced the battery. OK now it is Sunday 3AM and I get a health message from the car that the battery is extremely low. It was down to 4 volts and had to jump start and now have it on the charger. Will take it to the dealer 7AM in the morning. Nothing is left on and the only thing I did about a month ago was update my sync3 to version 3. I have read many forums and it seems some modules are not shutting down. Any help would be appreciated if you know anything similar about this.

akirby Posted October 8, 2018 Report Share Posted October 8, 2018 Your battery is at least 3 years old - time for a new one before you start worrying about potential problems. 3 years is about the life expectancy nowadays. Quote Link to comment Share on other sites More sharing options...

akirby Posted October 8, 2018 Report Share Posted October 8, 2018 He says the dealer replaced the battery a few days ago Oops - missed it in both forums. Likely candidates are the body control module and brake shift interlock. Shifter park detect is also a common problem but you don't have a shifter in the MKX.

IggyAZ Posted October 10, 2018 Author Report Share Posted October 10, 2018 UPDATE with more info Oct 4,2018 My car was hard starting and the Nav screen said it was shutting down things to conserve battery. I started the car and drove it to the dealer. Said battery was bad and replaced it and drove home and drove it on the 5th, 6th. Oct 7 2018 I look at the new updated MyLincoln App and I have a msg from car saying battery is low. (Oct 7 1:15AM) Battery was at 4 volts. Called Lincoln Roadside and verified and jump started car. Being Sunday I decided to keep the car and not have it towed to dealer and place on a trickle charge after driving it around about 30 minutes. Battery showed 12 plus volts. Oct 8 2018 Drove to Lincoln dealer and told him story above.Oct 9 2018 5PM Service Provider called and said that couldn't find any issues over night and put battery on charger and to come pick it up at noon on Oct 10. The only thing that has changed it I updated the SYNC3 to version 3.0 a few weeks earlier. Not sure which build and will turn off my wifi connection when I pickup car. Could that be the drain while parked in my garage? Thanks Quote Link to comment Share on other sites More sharing options...

Dave Posted August 1, 2022 Report Share Posted August 1, 2022 2016 MKX will drain the battery in 3 days, if left sitting as will all Ford Edges. If this happens the dealer needs to reprogram the computer which conytrols the rate of discharge allowed. I have had the issue twice with my 2016 MKX. Replace battery, if it tests fair or below and re-calibrate the computer which can only be done by your Lincoln dealer. The vehicle should be able to hold a charge for 7 days and a battery maintainer will not put out enough to keep it charged. Not a good vehicle to leave at the airport for 2 weeks while you go on vacation. Quote Link to comment Share on other sites More sharing options...
