Hello,
Looking for advice or anyone who has has a similar experience. I have a 2020 explorer. Recently I have been getting the system in battery saver mode message. I had the same problem a few months ago, the dealership replaced both the battery and the alternator. The car was fine until the end of September before the issue started again. Now not only am I getting that message when I go to start the car intermittently, but I am also getting a message saying charging system error. When I read the codes, I get 2 different codes one reading as powertrain control system low battery voltage and the other says all wheel drive module system voltage is high. I tried charging the battery which gave an initial reading of 12.3V and when the charger said done said 12.5V. Now on top of it I was driving at night a couple times and all the interior cabin lights plus the infotainment screen, and the dial lights for the HVAC all went out. The dash does stay lit. There's been a couple instances where when the auto start/stop activated, and then when I'd take my foot off the brake to start driving again, the car wouldn't move, so I had to push the engine start button to restart it again. That gave a message about hill start assist even though I wasn't on a hill.
Its also worth mentioning that as a volunteer firefighter, I do have lights, a control system, and a radio added. These are all separated from the car via a circuit breaker. In the spring after the battery and alternator were replaced and covered by warranty, I was basically told by the dealership that they wouldn't cover anything else because they believe its linked to the extra equipment.
Thanks for any ideas.
