My 2018 has been giving me issues with starting up recently. About once a month, it will crank for about half a second and then stop. Battery voltage will read 12v or less. I figured old battery, so I installed a new Interstate battery from Costco a few days ago. New battery's voltages were reading great around 12.6V with the engine off and 14.5V with the engine running. This morning, the Expedition would not start again and the new battery is down to 10.5V. All of our drives are at least 20-30 minutes so I'm not sure what is going on. The alternator seems to be working fine since it charges the battery back to full after jumpstarting. I'm thinking something is draining the battery?
Has anyone had any issues with a slow electronic drain or similar for their Expeditions? I'm going to take it to the dealership next week but am dreading it since this is our main family car and the dealership doesn't have any loaners.
