12v battery

On our previous ICE vehicle, when we were out of the country for 4 or 5 weeks, we had a small 5w solar panel that sat on the dash and plugged into a power(lighter) outlet. This would act as a trickle charger and keep the 12v battery topped up. Does anyone know if this would work on a (2025) MME?

We recently had our MME serviced for a front parking sensor failure. While they had it the dealer noticed two TSBs that were both software updates and so elected to take care of that on their own volition, which I appreciated. However, while running the updates in FDRS they managed to fail...

My wife and I took delivery of my wife's 2022 MME GT in July of 2022. So far we have had no problems or issues with the car at all. I recall reading in one of the tagged 12v battery information posts on this forum that 12v batteries usually last 2 to 2 1/2 years. Given that the 12v battery in...

New issue for me today on my '23 GTPE. Today my driver door got stuck open. The mechanism that pushes it open was stuck in the open position (see photo). It would not retract no matter how hard it was pushed. I didn't even notice at first until I pushed the door closed and it bounced open back...

I plug in my ‘21 daily with charge limit set to 70% pretty much every day since I’ve owned this car. Received the 4.2.6 last Friday, and car ignored my charge settings and went to 100%. Yesterday I get an alert to “Plug in to maintain 12V battery” despite it being at 96% SOC. I don’t have a...

I was going to add this to an ongoing thread about the correct procedures when parking the Mach E for long periods, but decided I might have set some kind of record, so... I keep a Build 1 (Jan 20) Mach E FE in a garage at a second home in Seattle area. It was parked in early March at 52%...

Hi all, Long-time reader, first time poster. My in-laws 13 month-old Mach-e started getting the "electrical system drain service required" message 3 weeks ago. They received the message 3 more times, and on the third time yesterday the vehicle went into deep sleep mode. I'm trying to help...

I don’t drive much, maybe 50 miles a week, and today a yellow warning message appeared when starting the MME about checking the 12v battery. After driving the message isn’t being displayed. The car is garaged and I have my charging level set to 90%. I charge the car when the range falls below...

I've had the car for 12 days. Yesterday, out of nowhere it starts giving me Transmission Not in Park error when I'm slowing down for a light or an intersection; a Door Fault Service Required error; and it also returned a Hill Start Assist Failure warning. These all came within an hour of each...

First time seeing this, showing “Charging 12v battery”. Car wasn’t driven for about 4 days. Upon plugging in seeing this on the FordPass application. Tell me this is normal.

So I'm pretty sure this has been talked about several times in the forum. Time for me to present my story. Before you ask, it is a First Edition, and yes it was built before Feb 3rd. I checked the Vin and it was built Dec 2020. To start, I took a road trip from L.A. to Chicago to be with family...

https://carbuzz.com/news/mustang-mach-e-owners-are-fed-up-with-dead-batteries I wanted to give everyone here a heads up, just in case. I haven’t yet seen any threads discussing this particular problem.

I was reading through posts on the drained 12v battery this morning, and found most of the replies seeming not understanding how to jump start the vehicle without opening doors or opening hood or opening covering inside the hood. And here goes the guide in Owner Manual, that it shows where to...
