Well it finally happened: car 12v battery is dead

[SonicBlue]

Never had this issue in over 50k miles.

Charged my car to 90% two nights ago. No issues. Drove my car to work this morning. Ended at 76%. Never received a LVB warning of any sort

Went out to lunch and it is DEAD. I was able to open the door by tapping my code into the door sill, even though the numbers didn’t light up. No screens lit up. Couldn’t even depress the brake pedal. While inside the car, I removed anything I needed and popped the frunk before closing the door again.

Obviously calling roadside service and towing to dealership but why other suggestions appreciated. I am under an extended Ford service plan.

Is the car on the original 12v battery? Just spitballing. Please keep us updated on this. Sorry to hear this happened though.

Yeah that is what it sounds like to me. Hope we're correct because if so, it's a very easy cheap fix for the OP, considering the alternatives.

Always replace the 12v battery before 36 months. Rinse and repeat and you should be fine going forward. Never wait for the battery give up the ghost stranding you somewhere. If you have the Ford Rewards points, they are 37,000. I just replaced mine last month at 34 months before any symptoms showed up.

fingers crossed a jumpstart will get you going and perhaps a new 12v will fix the issue.

36mth is quite short even for lead acid battery life let alone AGM.

Interested to know the root cause if it's not the 12V battery.
On a related note Hyundai Ioniq5 and Kia EV6 owners are also experiencing poor 12V battery performance.

I’m sure it’s the LVB. It’s just insane for it to fail so quickly despite regular charging and zero warning.

Ford wants $189, plus 18 core recycle, and they’d have to order it. What a joke.

Anybody know the Walmart equivalent that fits?

Are you just going to refer me to my dealership? I’m already in touch with them, thanks. And if you read this thread, you’d see that they’re not being super helpful.

I just replaced mine

I just popped off the panel to get access to the battery while waiting for the tow truck. Anybody know what the heck this is?! It was just hanging loose in the battery compartment.

Around here if you post that you replaced your AGM before it leaves you stranded, you are wasting money and resources. ?

Not all AGM batteries are the same.
So yeah, although 3 years sounds like a short life, the Mach-E is equipped with about 1/2 the battery that my F150 came with. Price might not reflect that accurately, but Amp Hours does.

That’s the washer fluid hose, it pushes onto the 90° barbed fitting at the right margin of the image. Just push it on.

is it the dealer you bought the car from? Maybe they'll pull one off a mach e on the lot? I
