Hudson 41 Posted July 7, 2023 Share Posted July 7, 2023 2016 For Fusion Energi So, i went camping and accidentally left my car in acc while unpacking and setting up. I turned it off and later the car trunk wouldn't open with the remote. I turned the car on and popped the trunk. When i turned off the car, instead of staying on for a bit like usual, a note popped up that said turning system off for battery saving mode or something like that. In the morning, i had to turn it on to get the rest doors unlocked and the trunk open. Then it turned itself to battery saving mode and the bar was really close to the bottom. When it was time to leave, it wouldn't start. So, i got the transer to jump it. Car starts, check engine light goes on and stop safety now triangle. I drove home carefully. Took about 20 minutes and the car drove fine. Got home and read the code: P0562 low system voltage Plugged the car in to charge. It charged for about an hour, which isn't much. I charge at a low rate. Went back out, unplugged the car, left it off, and checked the battery in the trunk. It read 12.59. Turned the car on and it read 14.81. The stop safety now light went off, but the check engine light is still on. I know sometimes it takes a while for that light to go off. Any thoughts on the situation? Where to go next? 0 Quote Link to comment Share on other sites More sharing options...
Hudson 41 Posted July 7, 2023 Author Share Posted July 7, 2023 (edited) Had the car plugged in for another hour or so, went outside and turned it on , the check engine light was off, and i drove it around the block with no issues. Thoughts? Maybe the battery is old and drained quickly? All looks to be fine now. Should is still look into a replacement 12v battery?

Going strictly off your description, it would seem you accidentally ran the battery down. If the battery is in good condition, it will charge with driving (or with a charger), hold a charge and all should be well. On the other hand, if it is weak, it may need to be replaced. The only way to accurately determine that is to have the battery load tested by a Ford Dealer or a competent shop. And a battery meter alone will not give an accurate battery health reading. Or just drive it and take your chances. In addition...How old is the battery? If it is older than 4 years, think about replacing it. Modern vehicles are very battery intensive, due to their heavy reliance on electronics/computers/electrical systems. So 3-4 years is what we can expect from a battery nowadays. And a weak battery can lead to all sorts of electrical and electronic gremlins. Keep us updated and good luck.

Thanks again! 1 Quote Link to comment Share on other sites More sharing options...
