Hello @TaxmanHog have you seen/heard info that will help ?

In reference to what?

Post 1050?
About dealers near Boston.

Thank you! It's a 2024 Lariat.. If anyone has suggestions for good dealers in the greater Boston area, I'd love to hear them.

I haven't seen enough posts with enthusiasm for any particular to make a recommendation.

North shore, metro west or south shore?

You might find some opinions in this section of the forum New England USA

yellow Powertrain Malfunction wrench and reduced power to 57%. Also won't charge past 66% or the orange ring of doom appears.

For my tracking spreadsheet, what is your build month/year (top or bottom of driver's door sticker), model, and whether SR/MR/ER battery size? With only 3K miles, I am guessing that you have a late 2024 model, which should have a lower chance of battery cell failures. Also check to see at ford.com if your VIN has Safety recall 25S18 for HV Battery electrode Misalignment (see that thread).

Build date: 4/24. No recall, though perhaps there should have been.

Well still in the shop…🪫and no known estimated completion date.

Well....I feel the frustration. I'm coming up on 2 weeks in the shop with no diagnosis as to the cause of the Powertrain Malfunction/Reduced Power. They said they are running tests but can't figure it out. This vehicle was our main transportation. Two kids. No rental or loaner. Fun times.

Check out the new poll asking about whether the Safety Recall 25S18 HV Battery Electrode Misalignment applies to you or not, previous module replacement or not:

Update on mine - Took it into the dealer on Friday (3/21/25). Looks like cell 90 in module 9 is out of spec. They're figuring out how to order a new module, but I took the car back as it's drivable and it will likely be a few weeks before the part comes in.

Well coming up on three weeks in shop for Powertrain Malfunction.

Called today and tech is waiting on call from Big Ford to help, all local Ford dealership techs haven’t a clue.

Oh, the app is showing some progress?!

2024 Lariat ER, 9.3k miles with the standard symptoms. Don't have the build date at hand because the dealership has my truck (is it on the window sticker somewhere?)

• 2/21/25 came out in the morning to the truck having not pre-conditioned, battery not fully charged to my standard setting of 90%. SOC was mid 80s
• Started the truck, got the yellow wrench, service vehicle soon, powertrain malfunction/reduced power, and 57% power available
• Replugged the charger and got a charging fault, amber ring of death
• Tried a few DC fast chargers that night to see, faulted on each of those as well
• 2/24/25 dealer started running tests, believed that the battery modules just needed reprogramming, no loaner available, no ETA
• 2/25/25 further testing, dealer found the bad battery module, still no loaner available but they're working on it, ordering battery module

I'm taking careful notes for obvious reasons and I'm planning to call the @Ford Motor Company BEV team to get the ball rolling, mostly in case I need rental reimbursement or additional pressure on the loaner front.

I'm very thankful for all the info you guys have shared here. I certainly wouldn't be nearly as proactive about the situation if resources like this weren't available.

Call with the BEV team went well. Case opened, confirmed the scenario qualifies me for a loaner or for rental reimbursement.

If we go rental, it can be from anywhere but has to be a ford vehicle. They'll cover $45/day for a sedan or small SUV, or $60/day for a truck or larger SUV. No mention of limits. I'm responsible for any tax (weird but ok) and they'll cover gas, just keep all receipts.

My truck is still sitting in the dealer's back lot, day 15. Apparently it took them a week after diagnosis to even order the battery module. I was given an ETA of 2-3 weeks for the module to arrive. No update from the shop since.

While I'm paying for a truck I can't drive, there were no Ford rentals in the area to be had. I finally put the pressure on the BEV team who in turned pressured the dealership and I did get a mediocre Ford Escape as a loaner which obviously does nothing to replace what I'm currently out.

Additionally, the dealership where I bought the truck didn't register my VIN correctly for the federal clean vehicle credit despite providing signed paperwork and assurances indicating that they had, so I'm fighting that battle, too. They've made no progress to resolve it yet, so I'm in contact with my congressman hoping he can help on the IRS side.

Overall, fully dissatisfied with @Ford Motor Company at this point.

Today is the 30th day since the dealer started working on my truck. Hadn't heard from them for a few weeks so I gave them a call.

They say all the parts are in, the battery pack is dropped, and they're working through the fix but I'm not confident. They moved it into the shop back on the 20th and I could see in the ford pass app that it was running a few times throughout the day, but they "got backed up" and there's been nothing obvious since then. Hopefully it's not just been sitting there open and gutted.

No ETA per the service advisor. He needs to get with the tech and let me know /sigh

It also just so happens that 30 days is one of the Ohio lemon law tests.


On an unrelated note, does anyone know when the '25s will become more widely in stock? I've been browsing black or carbonized gray Lariats with the tow package and 9.6kw pro-power and the pickings are slim.

In October I received the Powertrain Malfunction. Two modules were replaced. After the replacement the truck experienced serious range degradation. Several people on this forum suggested that the tech did not balance the battery. The issue was not huge a deal because I was not going long distance. Finally took the truck in today and their solution is to give me an entire new battery.

Only positive is my dealer gave me a loaner.

Please share the work order after the project is complete, curious to see the official P/N for a complete pack replacement.

Yeah that's seems...off
