NHTSA Complaint #11496872 — 2018 FORD EDGE

Only have about 13600 miles on my 2018 Edge and the battery drains down about .5 v overnight. Could not start in in my garage after 4 days of sitting, charged it up and took it to the Ford dealer where they did a load test on the battery, it tested at 89%. I did a load test with a multimeter with the same results. Dealer told me to keep a trickle charger on it because I didn't drive it enough which was a poor answer. There is a NHTSA #18V54800 out there and a Ford recall #18S25 that does not include my SUV but it could have the same problem. Looking on line there are others with the same issues with the battery going dead just by sitting and in most cases changing out batteries was not the cure and it seemed Ford offered no resolve. If this is a problem caused by a loose connection or a short it could indeed become a bigger safety issue. My vehicle was built at the same plant as stated on the Ford recall # and it should be considered a safety issue for all Edges of the model year of 2018 made a that plant. I'm not sure this is my problem but I need to start somewhere noting that it's happened to others besides me. Thank you for any help in this matter
