Powertrain Malfunction/ Reduced Power

[HRCC]

Last week my 23' started up with a stated 57% power and the wrench. I dropped it off at Norm Reeves Ford in Cerritos, Ca. They ran the error report and handed me the keys for a Mach-E to borrow while they took a look. On Friday they called to say "looks like a faulty cell. We're working to get a replacement and get it back to you soon."

I have to say, getting the Mach-E was a nice touch as I feel OK about still using the HOV lane and I have a long commute.

@Ford Motor Company just got the Powertrain malfunction / reduced power alert, service vehicle soon. :-( Power reduced to 57%. Just hit 4950 miles on my ‘23 Lariat ER. Service appointment for next Wednesday was the soonest available at my dealer. Just had the 6.8 OTA power up earlier this week and the front sensor CSP fix. Under warranty. Curious to see how long it’ll take to get repaired based on the other testimonials on this thread.

Do we know how common this is yet? I just got this for the second time today. I had a module replaced earlier this year. Time for round two...too bad because everything else about this truck is perfect. There's no way I would ever keep this truck beyond the battery warranty period when one of these module replacements would probably be $5k minimum.

Does this seem to be an issue with 22 and 23 models? Just breezing through the posts and I didn’t see any 24 models.

@FloridaMan655321
there was a 24 Flash that was reported having a bad module. Twitter: Lamonte Grulke
See my spreadsheet where I have been tracking reports.

Also joined this club.

2024 F-150 Lightning Lariat ER.
800 miles.
Got the "Powertrain malfunction / Reduced power message" just after turning it on. Had charged to 90% before that. No updates recently.

Guess I'll get a service appointment at the dealer that sold it to me and PM @Ford Motor Company to see if they can see anything on their side.

Following up on my truck - ended up being in the shop for ~3wks. Dealer gave me a loaner during it so they did the right thing. Here’s what the repair was. Dealer indicated that without warranty coverage this repair was quoted at just north of $10,000…~$8,000 was for the part alone. He also said the part number updated so Ford is putting a new Module Array type that hopefully fixes it for good…we’ll see. Really shapes my thoughts on purchasing the truck after the lease ends.

They’re replacing module 1 on my truck. Hs there been any rhyme or reason to the modules that fail?

Just got the message from the dealer confirming Cell 2 has now failed and needs to be replaced. Honestly, this is fucking bullshit. If I didn't love the truck so much I wouldn't be so pissed. @Ford Motor Company owes it's early buyers a full battery replacement with cells that aren't going to fail. I'm not sure what I'm going to do at this point. There isn't any other vehicle on the market that I'd rather have but I have zero confidence that this won't continue to happen.

Quoting CSP23B57:

“Less than 4% of the affected vehicle population is expected to require one or more high voltage battery modules needing to be replaced.”

The key words to my way of thinking are “or more”. Replacing one module with a cell gone bad is not a guarantee that you will not have another cell failure in another module the future.

I’m thinking their 4% may turn out to be an underestimate unless they have identified a specific time-bound issue in their quality records.

Ok, got my 2024 Lariat back (4 hours)

"WRENCH LIGHT CAME ON, FOUND CODE P0929"

"7001D4 MODULE - GEARSHIFT (GSM) - REPLACE
(7210/7D443/7P155) - L
99819 WF"


Apparently there was an issue with a bad batch of gear shift modules
