Hello..major charging system/battery issues. I got “shutting down systems to preserve battery” warning in March. Checked and replaced the battery, alternator output was good, 3 months later “service charging system” siren went on with red flashing alert on the display. Dealer could find nothing wrong, battery and alternator output still both good. “Bring it back if it does it again” was their advice. Last week the “service charging system” warning came back and VERY rapidly a warning for EVERY system came on and the car completely died, no power at all. Dealer says one of the connectors on the battery block wasn’t tight enough. I was an ASE tech (but also human) and I don’t think I failed to tighten the connector AND the dealer had the car in July and should have checked it then too. I don’t think they know what to do, I’ve asked Ford for help as well. Any ideas?
