probably true... more likely the OTA would not have started if the 12v SOC was too low. However, as vehicles age we may start seeing more problems as 12v batteries age-out, lose capacity after 3yrs, and can't finish a long OTA even if they start at 80+%
This has been an issue for a while already. I was lucky and the OEM H6 battery in my truck lasted 2.5 years before it started acting up. I replaced it with a quality aftermarket H7 and it's been great so far.

You guys have very limited space where your LVB goes. It would be great if there was a way to upgrade it to something with more capacity......,maybe there is.....never researched it.

There is room for an h4, BUT that would likely screw up the integrated BMS that is hard coded for 35ah capacity.... I don't think it would result in any longer life. Best approach for longer life with the AGMs is to charge to 100% about once a month.

I've just started a thread on this to try and gather more data on how the 12v batteries are aging, and how we all can get a better idea when it is time to replace.

I see it's a 2021 model year. How close are you to being out of warranty? Mine is already past 3 years I wonder what Ford will do then if they cause the issue.
I purchased the car in February 2022, so I am still in warranty.

I'm not sure if botched OTA updates fall under the general 3-year bumper-to-bumper warranty or under one of the other longer-duration sections. I can see an argument that this could go under powertrain or some other section since the issue affects all vehicle systems.

The warranty guide for the vehicle specifically says that Ford will cover damages caused by OTA updates during the warranty period. I would hope that in reality Ford would make its customers whole for issues like this regardless of the warranty status of the specific vehicle.

Not sure about this so I can't speak intelligently on it, but I think the BMS system is the same on my truck as it is in these vehicles. I fully charged my H7 before putting it in and reset the BMS and my truck recognized it at a capacity of 83 (when the max is supposed to be 80), so it knew a different battery was in there all on its own.

Well if the car can't drive, I would assume that falls under the 8yr/100k EV powertrain warranty.

Ford will also reimburse for the gas you pay for, after the fact.
does this hold true for Canada as well and for any time you get a gas rental for warrantied work? If so, what's the process for getting reimbursed?

I've had a couple of rentals so far and paid for gas not thinking twice about it. I always thought it would be nice to get an EV loaner when having my EV serviced......but figured eventually it would get there and paying for gas was better than having to pay for the repairs! haha

There's a difference between a recall, like replacing the HVBJB, and warranty work. The HVBJB includes a free loaner, and Ford should pay for gas if they don't give you an EV.

Okay, so then this post being about warranty work on the OP's car, Ford would not be reimbursing gas then in this case? Unless you are saying generally they reimburse for gas if an EV is not provided when a free loaner is called for (warranty or recall alike)

I thought all warranty work came with a complimentary loaner vehicle though? At least during the initial bumper to bumper....I'm guessing after the bumper to bumper it's not covered...even if it falls under the longer EV drive units and battery warranty?

No warranty work includes a free loaner. People need to read their warranties.

Ford will cover rentals as required if the servicing takes longer than a day and a shuttle won't work in a particular case. it's on an as needed basis but it is certainly a coverage provided by Ford for warranty service while in warranty. This carries out past factory warranty and into the extended paid warranties which cover up to 10 days of rental coverage during repairs.

The gas reimbursement is a new one though. I had never heard of that before so I was curious who/where you submit the gas receipts to and with what other paperwork to get your reimbursement approved.

Loaner is not stated in the B2B warranty. Ford MAY provide a loaner. MAY.

Yes that's exactly what I said. It's situational. The dealership determines if a rental or loaner is needed on a per case basis and then Ford has set criterial and limitations for the rental that the dealership has to follow. Beyond those limitations, the customer has some items or overages that could end up being paid possibly. It's pretty structured and defined.

My question is about the gas reimbursement mainly though. Since I've never heard of that before......could be a game changer....
