Interesting observation, should I be concerned?

[ZeroEmapthy]

I have a 2022 Lightning, had it since October, 13k miles on it so far.

Over the last month I noticed something mildly alarming. I usually plug my truck in 3-4 times a week, and all but two times I have charged it, has been at home.

Here's the interesting bit, I noticed my total range dropped from 220 miles at 100% to 206 about 3 weeks ago. Thought that was odd, so I decided to change my charge settings to just charge up to 90% to see what that would be... Still shows 206 miles of range on a 90% charge.

Now the strangest part, (I am a man of consistency if nothing else), When I charged my truck to 100% and did my normal day, I got home with 167 miles of range left, about 70% battery. When I charged it to 90% I STILL get home with 167 miles of range at 70%. During the winter (when I was interested to see how the cold weather would affect things), I would get home with 172 miles of range at around 78% charge. Keep in mind, during winter I had that heater maxxed out on my daily drive, and currently I am not using heat or AC, just blowing air, yet I lost 15 miles of range? Something has to be a miss here. Any ideas or tests I should try before calling ford?

I’d suggest you pay more attention to your actual consumption in miles per kWh than what the GOM shows. That’s a better indication of how your driving and use of the truck is affecting the range guessing. If mi/kWh is consistent over time, and your SoC varies without explanation, that may be a concern.

Temp causes variation. Can't look at range without temp. Truck is fine.

To compare range, simply divide range by %.

167/.70=239 miles

We call it the “GOM” for a reason.

My stock 22 Lariat ER w/ 1500 miles shows 300 at 100% which I think is off by 20 miles so yea , 6% off.

Hoping that’s just the GoM being off or me driving like a maniac

What do you mean, "6% off"? From the EPA estimate?

As with your gas powered vehicles, that's not something you should compare to for daily usage. 300 miles is your estimated range. Actual range is your miles per kilowatt hour x 131.

100% it's your guess-O-meter playing whacky games with you. Even your mi/kWh can sometimes be off depending on if you are driving short distance, up/down hill, or other factors that affect range (temp, wind, alignment of the planets, etc...). Bottom line for myself, if how much % of battery did my commute take? I average 6-7% to work, 7-8% going home. Unless I deviate from that by a large margin I know I'm good.

That said, are you charging to 100% every time? If you don't need 100%, you can help prolong battery life by only charging to 90% or less. I set mine to charge to 85%.

Yeah, I had 291 miles range this morning at 85%, that's 342 miles at 100%. The range display has nothing to do with battery capacity and everything to do with how you drive and driving conditions. LIke Captain Jack Sparrow says, it's more of a guideline really.

Right, sorry, the EPA estimate. I’m not actually worried cause I like to get on it.

Nothing wrong with your truck. It's just the way you driving. Start driving like a grandpa and you will see the milage will jump back up.

I have owned four EVs. Not all use the GoM in the same sense. It's an inherently flawed approach because it's estimating your remaining range on your recent past driving, which may be fine in terms of your particular driving style and maybe your use of the climate control (because those factors stay relatively consistent) - but it has no idea about how you are driving next in terms of terrain (incline/decline) or speed (freeway or in town). and expressing this estimate as an exact number seems to imply a precision that can be very misleading.

1. 2013 Nissan Leaf: GoM

2. 2021 Volvo XC40 Rechage: dashboard only showed %SoC but you could find a mileage estimate in the center screen. This estimate would only update in increments of 10 miles (unless you got below 20% and then it would try to be more precise), and it would also show you a "reasonable expectation range". In other words "looks like you have 160 miles left, but it could be as much as 190 or as little as 130 depending on what comes next..."

3. 2022 Rivian R1S: Shows miles remaining, but doesn't feel like a traditional GoM because the ratio between SoC and range seems to stay pretty consistent. So probably still a GoM, but not quite so sensitive to recent driving.

4. 2022 For Lightning: GoM

Out of all these I must say I like the Volvo range estimator best, because it's "honest" about the impreciseness of the range estimate. It seems to imply the proper mindset about what you have left in your battery - which is to say you need to do some nuanced thinking for long distance drives.

The guess-o-meter range will vary with temperature and your driving habits. Pay it no attention.

The Ford GOM is much more accurate than the one on my old eGolf. But, what I liked about the eGolf is that it would automatically adjust every time you changed the HVAC temp or turned on the seat warmers. Really helped a new EV owner understand. For instance. When I turned on the seat warmer it would drop from 120 to 119. Or when I turned on the AC from 110 to 94 etc.

It still amazes me how many people see the GOM low and their their battery is failing. Just drive your truck and enjoy it.

Update from Ford, need a new battery and a high voltage harness. They will be installing it on the 25th of this month. They didn't explain exactly what the issue is, but a couple days after this post I got a call from them, and they told me "A concerning issue is arising on my truck and I need to have it serviced immediately."

After some back and forth with them, the lady on the phone told me that according to the data they are seeing on the truck, it will need a new battery, and a replacement of the high voltage harness. All of it will be covered by Ford, which is nice, but having to drop my truck off on my birthday (for at least a week) is not so nice.

The new thing the truck does now is, limit my total motor power to 50% at random, (started the day I posted). Ford assures me that the truck will operate, but might be "slightly power limited," until my drop off day.

People can say what they want about vehicles with wifi connections, and quality issues and what have you, but this is one of the nicest experiences with a vehicle issue I have ever had the disposition of having to deal with. From the time I noticed something was different, to the time Ford called me about the issues was about a month. I am sure as time goes on, and Fords systems improve, they might actually be contacting people before they even realize something is wrong, and thats pretty cool in my book.

Thanks for the help and suggestions guys, but I know vehicles, when something is off, I am usually pretty quick to spot it. To those talking about temps and driving style, my truck had better range when temps were almost 30 degrees colder outside, and I was using more systems (mainly the heater), so driving habits and environment should have favored me in the past 4 weeks, not hindered me. The one thing I wish we had on the dash was an actual readout for how my Kwh of battery we have, instead of a % based bar.

Sorry it's the battery. I hope everything goes well for you.
