This problem seems to happen with many Fords. My battery is almost 6 years old now. I have had the symptoms for about a year now. No start stop, radio powers off, no Fordpass, no keyless entry, etc. However, AGM batteries do a better job at hiding symptoms of a bad battery than lead acid. An old AGM battery will still start the car, but the battery will be very slow to accept charge.
Some battery testers can be fooled by AGM batteries. Conductance testers estimate battery health by sending a tiny AC signal into the battery. AGM batteries will often show normal voltage, okay conductance, and acceptable internal resistance even when the battery is old and nearly worn out. Battery testers that actually put a real load on the battery will reveal the true battery health.
The Edge is equipped with a slightly smaller H6 battery, while the Lincoln Nautilus is equipped with a slightly larger H7 battery.
When testing, what does the ambient air temperature value show in the live data? The heater may be commanded on if the ambient temperature is below 5°C
(41°F).
I did mine as per that TSB - its a robust fix.
I had the collars in hand but they were too bulky for the available clearance around the shaft/tube - I had all the materials on hand to apply the TSB solution.
Does the Edge have an undersized alternator? I do drive many short distances, but it only takes a couple of trips for the start-stop (yes, I know everyone hates that) to stop working and in about ten days, I get the battery saver message and all but the driver's door cannot be locked/unlocked from the outside. I have had the battery checked and replaced, but the problem did not go away. I bought an AC battery charger (Battery Tender) that plugs into my cigarette plug. I keep it on the charger when I am at home. It is a pain since I have to roll down a window to plug it in, but I do not want to get stuck somewhere. I have the first electric Edge!
