Grieves me to post this: completed online sale of brand new '24 Lariat ER with 47 "test drive" miles on odometer.

She's a beauty in Avalanche! Took possession May 9, 2025 in Maryland. During orientation with salesman in the cab, the gear shifter never laid down flat. Hmmmm; an $81k product with something that doesn't work on it??!! Should've walked away.

Drove it off the lot in positive adrenaline rush in spite of the shift knob not folding flat. Live in metro ATL, so a long drive awaited me.

At 200 miles or so, Amber Wrench icon stares at me...wtf is this? "Service vehicle soon" Say whaaat??!!! "Powertrain malfunction/Reduced Power" illuminates when the system has detected a powertrain or a four-wheel drive fault." Still drives fine for now.

If memory serves me correctly, the icon appeared AFTER my first charge session at a Tesla site. A friend loaned me his adapter. Charged fine and fast. With Amber Wrench on, I continued driving until next charge session. I called the dealer about the wrench icon; they said it may have something to do with the heat generated by the Tesla charger at such a high voltage rate (I have zero technical aptitude), and to avoid using Tesla chargers, and just rely on Ford Navigation in the vehicle. So I did.

Got to a Duke Energy charger/EV Connect, which was great. Wrench still on. Got to next charging station, pulled up, went to put truck in Park, and it was STUCK IN DRIVE with a tiny amber light blinking continuously next to the D by the gear shifter. Called dealer, who said "Call Ford roadside assistance and have it towed to the nearest Ford dealer, and we'll call you tomorrow morning."

This was around 6pm last Friday night near Mount Airy, NC.

My PTSD sure enough DID KICK IN, and I went off on the Sales Manager at the dealership in Maryland for obvious reasons. Tow truck driver was great, dropped me off at a Hampton Inn ($258 for the room), and dropped the truck off at the Ford dealership across the street.

The next morning I walked to the truck, opened the drivers door, did NOT enter the vehicle, and to my shock, I watched the gear shift knob move by itself from Drive to Park. THEN, I got into the truck, pushed the POWER ON button, put it in Reverse, back out of the parking space, then put it in Drive and drove to the front of the dealership, where I told the staff I was "fine" and resuming my trip to Georgia.

The amber wrench icon disappeared somewhere in the mix. Drove fine all the way home, using Blue Cruise on the interstate with no problems.

I'm too new of an owner to know what to look for on the far left side of the battery charge level.

The dealer that sold me the truck was kind, but what idiot buys a vehicle out of state, never seeing it, nor test driving it, and never done business with this dealer before??!!! That would be me.

I called the BEV Team Friday night from my hotel room. He noted details in writing. The dealer in Maryland contacted my local Ford dealer where I've been doing business for years (they don't like BEVs, or else I would've bought from them)(should've been a clue), and I have an appt tomorrow to address the AMBER WRENCH ICON, the stuck in D gear shift issue, and the gear shifter not folding down flat.

My '17 F150 was the best truck I've ever driven...not a single issue from the time I drove it off the lot brand new 9/30/2017. How am I supposed to interpret this debacle?

Sounds like you just have a bad gear shift module. Dealer sold you a load of crap about it getting too hot. If you can charge at all, you are fine to charge anywhere you want. A bad battery module would prevent you from charging over 60%'ish.

More and more I'm thinking about swapping mine out for the rotary shifter.

Yes it's probably just a bad shifter that needs to be replaced. Things break and that's life. The dealer sounds like an idiot. Hopefully it all gets fixed quickly. Don't over think it.

@JIMINGA : The earlier responses are right on point. This has been seen many times here and a replacement will resolve that issue.

Sorry you had trouble after your purchase. I would imagine that you are quite frustrated, but sounds like it may just be the shifter which a few people have had trouble with. I purchased mine in Maryland (Upper Marlboro Ford) mid March last year and drove to Georgia to pick up some equipment and then drove home to Texas without issue. Hopefully they get it fixed for you quickly and you come to love it as much as most of us love ours.

It turns out that I have one out of range cell and that battery module needs to be replaced.
We just got our Lightning back - just a week after being told it would be at least two weeks for the parts to come in, so kudos to Yonge-Steeles Ford Lincoln for fast service (or, at least under promising and over delivering!).

Looking at the paperwork, it says, "REPLACE BATTERY ARRAY 1"

Took my “less than 1 week old” ‘24 Lightning to Akins Ford (Winder, GA) May 14 to address the amber wrench/service vehicle soon issue. Replaced gear shifter and I picked up my truck less than 48 hours after dropping it off. Loaner was free too. It’s May 16…let’s get this Lightning going now!!! Kudos to Akins Ford Service Team (Russell R.) who knew what to do, followed Ford diagnostic procedures, discovered the problem, had the replacement part in stock, and completed the job fast!!!

Well it’s only been less than thirty day since last yellow and red wrench. Last red wrench in March of 2025 almost in shop for thirty days.

Well yesterday the yellow wrench came back “service soon” then today turned red.

Six times in less than a year…

“Powertrain?”

Ford what’s up??

They told me that a battery module needs to be replaced and it would take a couple of weeks for the part to arrive. Since the vehicle is drivable, they said I can just bring it back when the part arrives.
Just wanted to provide an update. Battery module arrived on May 6th and I left my truck at the dealer on 8th. They gave me a loaner (brand new F-150 STX) and said it would be a few days. May 14th, they said battery module was replaced but then they got another code indicating another module failure. May 27th, message me saying another module is being replaced and existing 2nd keyfob won't work any more and they will give me another fob (no idea why). Yesterday, another message saying battery module has been replaced, but something went wrong during programming and has caused multiple error codes and now they are waiting on Ford to tell them what to do!

Seriously, you need a different dealer to service your vehicle.

Actually, I think the service department at Billy Howel Ford did a great job. I got my truck back today and everything appears to be great. They updated firmware for all modules (they had to). In talking to the service advisor, it appears that it was quite a journey. Here is what was on the repair order. They had to go back and forth with Ford several times, so I can't really blame the dealer..

--
Concern

Customer states vehicle will stop charging after 60% and will not go any higher check and advise

Cause

Verified concern. Connected VCM, checked DTC's, found POB24:21 stored in BECM. Checked OASIS, found no information available. Followed WSM to 414-03А, PPT AP. AP1-no, AP2-yes, AP3-no, AP4-yes. Performed BATTERY HEALTH test, found HVB module 6 faulty. Ordered HVB module 6. Customer took vehicle.

Upon customer's return, performed BATTERY HEALTH test and found both modules 4 and 6 now fail. Opened TSR for further instruction as values for module 4 as well as battery state of health value seemed implausible. TSR directed to order BECM and directly test module 4 using XMB. Performed testing of module 4 and confirmed individual cell voltage variance exceeded .030V, condeming module.

Correction

Replaced HVB modules 4 and 6. Performed HVB battery balancing. Module balancing failed several times using MB balancer. Balancing succeeded after repeated attempts. Installed new HVB modules into battery pack. Installed new BEC per TSR instructions. Reinstalled HVB into vehicle. Performed PMI on BECM. Performed cooling system bleed procedure. Cleared DTC's, none returned.

MT utilized for time spent for TSR and repeated module balancing attempts.

Reference TSR ID:120964822

Updated BCM, DC/DC, SOBDMB, OCSM, HVAC, ACM, APIM, TRM and RFA modules. BCM failed updating and set U2100 and U2101 DTC's after programming. Contacted TAC. TAC reported server data error occured. Server data was corrected. Performed PMI on BCM. No DTC's returned. M time utilized for time spent programming on TAC contact. Reference TSR ID: 120964822

2024 Ford Lightning Flash
Had the powertrain malfunction/reduced power (57%) three weeks ago. Took it to a local Ford Dealership and five days later I received my truck back all fixed.

They had to replace the HV battery module 7 due to failure. I have a 2024 Flash trim June 2024 build. 31,000 miles.

I'm a little concerned about these SK Technology batteries. I wonder what the failure rate is on these.
