Powertrain Malfunction/ Reduced Power

[bordner42]

It usually adheres to the state you purchased in, so NJ in your case. My quick search says 2yr/24k miles.

Yeah I'm doing additional research and I'd be fairly upset if it was didn't qualify because I was 2 days and 224 miles over.

Sorry to hear that you have also lost two battery modules in 24k miles. There are two issues here. First, you are out your truck for at least 2 weeks, and second, there are still 7 other original battery modules in your truck, any of which could (and probably will) go bad at any time. I have become leery of taking my truck far from home for this reason. Meanwhile Ford is stalling on my request for a buy back.

Could only be 6 original battery modules after this! They didn't say which failed, so might not even be the prior replacement one that failed.

there are 9 battery modules, so could be 7 or 8 original modules still left after repair. There has been one report of someone having 3 modules replaced (see my tracking spreadsheet in my signature below). Speaking of which, what is your Build Month/Year shown on your driver's door sticker at the top? Early 2022's seem to have the worse luck, but even 2024's have been bit by this long time delay repair. If the battery module replacements could be done in a few days, instead of weeks, the pain would be less severe for everyone, including Ford for fewer lemon buybacks. @Ford Motor Company

Have you looked at how many of the failed modules are related to battery cooling system failures? Anecdotally I have seen several cases where either a diverter valve or a heater assembly (like my case) was correlated with bad modules. Presumably the cooling system is necessary, especially while charging, so it stands to reason that cooling system failures could be at the root of at least some of the module failures.

Yes, that would make sense. The 96 battery cells, made up of either 4 (SR) or 5 (ER) pouches, expansion and contraction, due to charging and temperature variations, are being stressed. Also, @MickeyAO implied that testing showed bigger "depth of charge"s (say, 10-100% vs 50-70%) were more stressing on the batteries. Normally, the cooling & heating system should minimize the temperature factor.

If you think about the concept of people who have had multiple modules fail, you would think Ford would have a 6 Sigma team all over data collection trying to get to root cause on these failures. The numbers of just casually voluntarily reported failures to a Google sheet on a forum, which is probably a fraction of actual failures, out of the fairly small population of vehicles in the field suggest they have a pretty big issue on their hands.

Update: Here's a quick report on my surprisingly positive experience with the dealer. First off, they sent a valet service to pick up the vehicle from my home. Later that day, the Service Advisor called me with the diagnosis: Bad HVB module #3. They ordered the parts and said it would be 3-5 days. He said I could drive the truck until the parts came in. I started out with around 75% and he requested that I return it with at least 50% SOC.

While the vehicle was there, they performed two recalls: 24B56 - Front parking sensors, and 24P24 - Front hatch control module. The valet service then delivered the truck back to my home. Both recall procedures went well. I did notice that the red LVB battery dash light was on. I plugged the charger in and was surprised that the red ring of death was gone and the truck actually started charging!

The next day, the SOC was at 90%, the LVB battery was recharged, and the red dash light was off. However, that was short-lived as the red ring re-appeared and the powertrain malfunction notification returned when I tried to charge again. But I was still able to drive with no problem.

5 days later the parts came in and I took it back for the module replacement. They said it was a very complicated process and could take 3-5 days. I was expecting the worst. To my great surprise, they called later that day and said it was all done! They also did the 24S76 Upper control arm nut replacement at that time.

So I'm back on the road after less than a week. They performed 3 Recalls and a HVB module replacement. I'm extremely pleased with the exceptional response by the dealer (Larry H Miller Ford, Draper UT). I don't know how they could have done any better. Hopefully I can still say that after driving it more, but so far, so good!

Oh Man! You can add me to the same spreadsheet. I am scheduled for serviced to START looking into this 57% maximum battery issue. This started out of the blue. From reading all of these posts, it encourages me to make sure I have everything documented and potentially prepare for very drastic changes (e.g. buy back is crazy to think about).

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.

Make sure they check for heater/cooling system faults. A lot of the failed module cases also have low coolant and/or a faulty diverter valve or bad heater (and coolant pump) assembly.

The build date is on the window sticker at the top where it says "blend".

And sorry to hear your troubles I went through this myself almost exactly 2 months ago. You're doing the right thing reaching out to the BEV team right away. The fact that your truck's issues have already been diagnosed should speed up the process to get you a loaner or rental reimbursement once your repairs are done. Feel free to reach out via DM if you have any specific questions. I've gone through a buyback as well after 30 days cumulative in the shop - I was sitting at 7 days in the shop for other unrelated issues before my battery module failure 2 months ago.

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.

Got the dreaded orange wrench this evening after meeting my wife for dinner. Also had a strange clicking noise coming from near the charge port. Was able to travel home at normal speed.. I am charging now, with blue ring.

FordPass showing Power Malfunction / Reduced Power? , like only 57% available power? See the HV Battery Electrode Misalignment thread as well, and check your VIN for that Safety Recall 25S18.
