I think it is more important how long the battery sits at a specific charge. Leaving the battery at 100% for a week is much harder on the battery than if you charge it to 100% and then drive shortly after. So if you charge to 100%, drive around for a week until it gets to 50% and then charge it back to 100, the battery is sitting still at an average of 75%. Or something like that. It isn't sitting at 100%.

For example, Ford does not recommend storing the car for a month with the battery charged to 100%.
I tend to agree. When the MME was my daily driver (75k miles in 27 months).....I charged to 100% everyday.

Now that it is passed off to the spouse, it only gets charged to 90%. Could probably go to 80% and be fine too.

In a strange twist of fate....
I am driving a Polestar 2 now. It lacks some features that I enjoyed in he MME but PaaK works perfectly. When I say perfect.....I mean EXACTLY just like having a fob. In fact, I am not sure where my fobs are. I have them in drawer someplace...

Interesting that they drop the tenths at 100k. Harkens back to the original display so many of us probably remember.

I bought my 2023 Mustang Mach-E Select on July 31st this year. 10 days later I got the SVS festival of lights. Typical Ford service, "Make an appointment...we're booked for three weeks...we have to order a new HVBJB...blah, blah, blah". It was still drivable and seemed fine, but I refused to charge it anywhere but home until after the HVBJB got replaced.

They ended up replacing the HVBJB with one that caused the SVS "as soon as it left the bay". I got two HVBJB replacements on one work order. I am not sure if that counts as two for lemon law purposes but we will see.

This is my first weekend in two months I can drive it and charge it at a public charging station. I need to find the good charging stations along the routes of my favorite destinations between San Francisco and San Luis Obispo. I live about half way between the two and California has plenty of charging stations, although over half of them seem to be for Teslas.
Wait, you bought a 2023 MME and had the HVBJB issue?

Any other maintenance besides the HVBJBs

Excuse my ignorance, what are the HVBJB’s
I’m assuming High Voltage junction boxes?

High Voltage Battery Junction Box

I would not call it a maintenance item. It is a part that is failing prematurely on some cars. The HVBJB has yet to fail on my car, and I have 34k miles. And I smash the accelerator to the floor every time I drive it. I don't drive at excessive speeds, but I set the cruise for 80 mph when on the highway. Which is multiple times a month. So I am not babying it at all.

That said, I think the percentage of 2021 failures is high. Personally I would not worry at all about a 2023, or even a 2022 produced after they switched to the new HVBJB. Well, actually, I don't worry about it anyway even though I have a 2021. ?

As far as maintenance goes, I replaced my cabin air filter a couple weeks ago. That is it so far! (I do need to replace the windshield wipers, but I have been procrastinating.)

I am wondering. Have you had to replace or has anyone had to replace the front electric drive assembly? I currently have 103,000 miles on my Mach-E 2021 Premium Ext Range and the cost to replace is $4100.00.

Not much more than, or not even in some cars, the price of a turbo blowing up on an ICE car.

Now at 75,000miles.

Car still works reliably

Still always get a charge on the road

Not yet died of range anxiety

Neither battery or any of the arrays spontaneously combusted without warning

Neither entire battery or any of the separate arrays have died

Sorry and ? to all the anti EVers

I have not seen anyone in the forum say they’ve had to replace the front electric drive assembly. I’m thinking I missed it.
I recall seeing a post from someone who had to replace a motor assembly. Not sure if it was the front or not, and it was not due to age or wear and tear. It was defective.

Does yours need to be replaced?
