2023 ER Lightning Lariat, have never had a single problem with the truck, until.......

Last night charging fault warning on the app but truck charged to target of 90% at home. I tried to drive it this morning and although truck is charged to 90% I have the Powertrain Malfunction/ Reduced Power warning on both the truck and the app. Also included is a High Voltage battery warning. The truck will only drive with power to 20%.

I drove to a dealer and they said it would be 2-4 before anyone could even plug it in to look at it. I called around to other dealers in DFW and they were all worse, quoting 7-14 days before anyone could look at it and encouraged me to keep the 2-4 days appt.

Well, I didn't notice a problem with the truck, driving, except it doesn't accelerate with only 20% power so I limped into the dealer like I was driving on a spare tire. Since I don't think it's functional enough to drive, I just left it at the dealer and got a courtesy shuttle back to my house. No rental. I will have to share my wife's hybrid for awhile until we find out what is wrong with it.

From talking to several Ford service depts today, I learned Ford is short a LOT of mechanics as confirmed by the article posted on this forum. Also-- specifically EV technicians. Most dealers only have one and the lightnings are backed up according to their schedule. One service manager said, "Yeah we have a lot of lightnings right now we are trying to schedule." Sales manager said they can't sell them and "nobody wants to buy them."

I hope it's something easy to fix.

Reading other posts in this forum, I agree, this is my favorite vehicle of all time to drive, hands down. I use it as a truck regularly and there's no way I'm ever going back to an ICE vehicle or truck. If the vehicle will be a problem going forward, my options are Rivian, GMC and Tesla. It sounds to me like GMC is also backing out of the EV game and their trucks are very expensive. I don't trust Rivian in terms of long term reliability. That really leaves the Cybertruck. Even though it's really ugly, I do trust Tesla to be at the forefront of EV technology and trust their product and long term outlook with EVs. I traded my Model Y for the lightning when I needed a truck. It seems in the US, others are still trying to catch them. In my opinion, right now, if you want a truck and want EV, tesla has the most reliable long term outlook. I hope I'm wrong bc I'm not a fan of the cyber truck and my lightning is honestly the best vehicle I've ever driven.

I will keep anyone posted who is interested.

20% available power is a new one for me. A lot of battery cell faults reduce the power to just above 50% but it could still be a battery fault or something else. "powertrain fault" is essentially the check engine light for the lightning, could be anything.

The service advisors should be able to pull telemetry codes to start and at least give you an idea of what may be happening.

Same story for me this past week except power was only reduced to 57% on my 2022. Dropped it at the dealer on Tuesday night and waiting on diagnostics to be run -- they called at the end of the day yesterday and said they'd need today to complete them and will update me when they have results.

Just curious, what is the wait time to get an EV mechanic to look at it? DFW is anywhere from 2 days to 14 days just sitting in the shop in line for them to plug it in.

Rental? Loaner?

Keep me updated on your case as well. Thanks for posting.

My closest dealer (5-10 minutes) said drop it off and we'll get to it when we can.... didn't take it there. The dealer 25 minutes away told me on Monday they could look at it on Wednesday, so that's where it went.

Loaners at both dealers were quoted at weeks-long waiting lists, though the dealer I ended up using did say they prioritize based on severity of the issue, for whatever that might be worth. Given that mine will charge to 66% and has drivable power available, I expect they'll return it to me while waiting on whatever (*cough* battery module(s) *cough*) they need to order for a future repair.

Ha, as I was typing this, the dealer called and said they were able to run a diagnostic on it and the high voltage battery cell #4 has failed. They have already ordered another one, estimates it will take at least a week to arrive to the dealership with approx 2 day install. Their loaners are backed up starting Nov 21st. I was given the phone number to call Ford to try to arrange a rental. 800-392-3673.

I'm glad the service dept was able to at least diagnose it and order the part before 1-2 wks wait at other places around DFW.

Update... Day 6

Module still has no ETA on arrival at the dealer. Parts says it looks like it has shipped, but no confirmation on that. Picked up a loaner (Bronco Sport with ~350 miles) today since they didn't have one available before the weekend.

Seems ok, but definitely hear the road noise more than in the Lightning. Thought it must have AT tires but nope.

Only drove it the 25 minutes back from the dealer today. We'll see how it feels over the next week or 2 or however long this ends up taking.

Just picked up truck completely fixed and freshly washed from the dealer in DFW right now. At a cost of on-the-house. I have to say I'm impressed. It was diagnosed and fixed a LOT faster than I expected. I picked up it on the third business day. It seems be driving normally and I'd already forgotten what a joy it is to drive this beast in sport mode.

Yes, and thank you Ford.

What did the work order say?
Just to confirm the module 4 was the only issue!

with my recent MODULE 7 replacement, I saw the same "Powertrain" and "Electric" system alerts, loss of SOC while parked, and the lower 'Power' output....although the truck showed no noticeable negative driving characteristics in the meantime...

the Powertrain alert was probably the tip-off of the potential low cell Voltage...

- the local Ford dealer diagnosed the cell Voltage issue in the first day or two it was in the shop: I could see via my FORD app that they were doing self-diagnosis for the first day - , "PLUGGED IN", "PARKED", "TRUCK IS ON", etc. and several "CHARGING ERROR"s along the way...

- they got to the Cell Voltage issue, and verified what to order: Module 7 11.95kw. They also would have to have on hand the pack/module CHARGER Unit, the battery platform to drop the pack onto, etc., and the tech knowledge/education to pull off FORD's instructions to get it done.

- the Module came in via a crate in several days.

- several days later they had the truck up on a lift, and had dropped the battery pack, and had removed the pack COVER, and the crated module out

- a day or two later, they were finally shown on the revived FORD app as "Power ON", seen moving around the dealer lot, and finally PLUGGED IN and CHARGING, at 70%... and a call a few hours later

it was a LOT of patience. I finally feel FREE! to drive around in such a smooth ride, with such POWER! Amazing machine.


Please don't take it away from me again!
