I've had an issue which seems common when searching the forums, that the truck wouldnt charge past 80%. It would get to 80%, jump to 100%, and then as soon as turning on the vehicle drop to 79%. I initially took my vehicle into the service department on May 15, and i have had multiple issues with the dealer asking to contact Ford Engineering which then took weeks to respond. I am hoping that @Ford Motor Company might be able to help get to the bottom of this and prioritize the work. Below is my timeline of events:

Below is an outline of my experience with Mike Bass ford and the delays in repairing my vehicle. As of now it is still not repaired and the technician does not believe he can repair it without Ford Engineering support.


TLDR - took truck in on May 15. The technician claims it took 2 weeks for Ford Engineering to help him diagnose the issue. Then it took 5 weeks for the parts to arrive. Now he is saying there is a new issue, pictures have been sent to Ford Engineering, but he has not received a response.



2025 Dates of Service

Thursday May 15 - Service appointment to truck. Truck would not charge beyond 80%. Identified this as a common issue online. Shared this link when checking in with the service department. https://www.f150lightningforum.com/forum/threads/truck-refuses-to-charge-past-84-87.26182/

Friday May 16 - Took vehicle home. Technician said he needs to contact ford to confirm the issue.

Wednesday May 21 - Emailed and asked for an update. Service responded with “I will ask the technician asap & get back to you shortly.” I did not receive a response.

Thursday May 22 - Emailed again asking for an update. Did not receive a response.

Between May 23 and June 12 there were 8 phone calls from me to the service department asking for an update on the issue. Most calls provided no update or no response was received. Eventually told parts needed to be ordered, I believe this was on 5/29 or 5/31. Decided to stop calling and text or email going forward so everything was tracked.

Friday June 13 - provided a rental vehicle. Initially told that no loaners were available but due to my need for a working vehicle which can travel more than 100 miles, service connected me with Hertz to arrange a rental car. at this point, the vehicle would only charge to 60% so I needed a new vehicle. I was very happy with the service center and Hertz for getting me into a vehicle.

Monday June 16 - Asked for an update on the parts via email, no response

Thursday June 19 - Asked for an update on the parts via email, received response that all of the parts were not yet delivered

Tuesday June 24 - Asked for an update on the parts via email, no response

Thursday June 26 - Asked for an update on the parts via email. Response received on June 30 that the parts had been delivered and I should drop off the truck

Tuesday July 1 - told that the technician would not be able to work on the truck that week but that I should bring it in.

Wednesday July 2 - brought in my truck and received a loaner vehicle from the dealership so I could take back the rental. The vehicle smelled like cigarettes but I figured I would leave the windows down to air it out.

Thursday July 3 - I could not stand the cigarette smell and asked for a new loaner vehicle. Service was able to arrange a new truck to be sent to my house and they picked up the cigarette truck. The rental vehicle was also returned.

Wednesday July 9 - asked for an update via text. Received a response from service that the technician has not provided an update

Friday July 11 - asked for an update via text, no response

Tuesday July 15 - asked for an update via text. I was told, “i just got an update he does have the truck apart right now and he is in the process of putting the new battery array in the vehicle. He has to work with ford engineers on this because the new battery array will not hold the charge.” Then later in the day I received this update, "
Yes so i just talked to him again he had to submit a bunch of photos that ford asked for he has not gotten a response yet after he sent the photos. He is not sure if it is a charging issue or the battery cell issue now . I will let you know what he tells me next"

I think they are on the right track - bad battery cells.

It is typical of Li batteries that they will tell you they are fully charged to 100% but really aren't right around the time they fail, at least that happens in things like Laptop batteries.

So it's good that they will be replacing them, but of course inconvenient as &*($.

Of course charging to 100% all the time is not good for them, even with the head room built in.

Appreciate the confirmation.

Agreed, I rarely charge to 100, but get close on road trips. But by the time I turned the Truck in it wouldn't even charge to 60%.

Had some good news today - got an alert on my phone that it was charged to 80% and they were charging up to 90% as a test. But now I see a charge error and its stuck at 83%.
