Truck seems to have some range issues? 2022 XLT SR at 80% charge showing 140 miles of range?

[Yellow Buddy]

A lot of factors affect range, but unless an update changes available battery capacity, it’s not one of them.

Yes…yes there are. I’ve documented many of my trips with OBD readings. That includes speed, temperature, ambient as well as battery temp. I also baseline my consumption at a base speed with ABRP at an average clip of 3,000 miles per month specifically on the Lightning. The majority of which are long trips and not short ones.

Then considering I’m taking the same routes that drains from 100% down to under 5%, DCFC charging back up to 80-85% before draining it back down to under 5% in one continuous trip while tracking my average speeds, real world miles, time to arrival, and kWh I paid for to recharge..

I’d say I have a good idea of what my factors are. There have been updates that affected GoM only, certainly. The majority of them affects only the calculation. But there was one earlier this year that affected consumption, I saw an average of ~25% drop in mi/kWh for the entire duration of that update.

Something very similar happened to me, albeit on an older firmware. Back when there was still a truck icon in the corner of the UI, I started the truck and instead of the Lightning, I saw a white Mach-E there. While driving my range fell alarmingly fast along with my actual battery percentage.

Had only driven maybe 5 miles on the highway and my percentage dropped from 67 to 55%.

I knew something wasn't right so I pulled over. After thinking it over, I disconnected the 12V battery, let the it sit for a minute and reconnected it.

Everything was back to normal and my battery percentage was now reading 66%.

Never had the issue again, but just know weird things can happen.

Might be worth giving a 12V disconnect reset, a try.

Reset EV driving history. Done.

It’s time to take it in.

Hi all,

I'm having some issues with the truck as of late. At first the last few days when I would drive it and turn it back on, I'd see something like 10 less miles of range after sitting for an hour. So I'd get to my destination with like 80 miles, turn it back on, and the range shows as 70ish miles. I thought it was weird but figured who knows maybe just a little issue that would work itself out. Last night, I left it on the charger to charge to 80% and I woke up today and unplugged it from the charger and its showing 80% as 140 miles of range??. I only ever charge the car to 80%, I've charged it past that at lvl 3 chargers maybe 5 times over the course of its life. Has anyone experienced anything similar? Will be taking it in to the dealer but I wanted to see if there's another way to get an idea of battery capacity from my end before I do. Thank you!

Also I live in North East USA so the temperature is like 80 degrees F outside so its not a temp related thing.

Since you have the SR battery pack (~100kWh), and the software update that shows numeric SOC fulltime, simply multiply displayed SOC x 2, and that’s your range (reasonable approximation). If you’re planning to drive mostly 75mph, subtract 10% from that range. If you’re planning to drive mostly below 50mph, add 10% to that range. Easy mental arithmetic.
No GOM needed. Range is determined from SOC, and I bet you can do that better than the GOM.

The GOM acts in mysterious ways!

From nearly six years of driving an FFE, it appears that the GOM works by combining current conditions with recent driving history, with a heavier weighting on the most recent events. In other words, the last mile you drove has more significance than possibly the 10 miles before that, which is possibly more significant than the 100 before that, give or take.

In the end, the GOM is in the same group with weather forecasts.

Hi there, I'd be happy to look into your Lightning concerns on my end. Will you send us a message with your VIN and dealership info? I can look into things on my end.

Sent you a msg, thanks again for your willignness to look into it!

Have you recorded what your consumed percentage was on a few trips? As somebody else mentioned, because it's an SR, the math is really easy to check. Write down battery percent at beginning of trip, then divide miles driven by battery percent consumed at the end. You should get something better than 2 for most trips. If not, then something might be wrong.

This is what it looks like over the full 9500 miles. It's been fine up until like two weeks ago so I'm wondering what lead to the huge discrepency

No trailer profile, never towed anything with the truck. It's been super accurate in the past with giving me a range of like 190-200 when at 80% and so I'm not sure why the drop all of a sudden. Nothing has changed about my driving or anything but yesterday I ended up at 10 miles on the GOM even though I should've been closer to the 50 mile range based on distance driven.

Even if you've never towed, you might double check if there's an active trailer selected.
Aside from that, I would suggest charging it up to 100% one time to see if that triggers some recalibration. That has worked for me in the past.

It may show low than expected range but at least you got the update to show your % of battery..... I still haven't got that update

So you show 2.4 MPK for life. What’s your MPK now?

He's already done that. I've been thinking about this. Try selecting the default trailer. See if the GOM changes then select no trailer.

I keep coming back to the trailer thing because that is what the GOM does when you select a trailer.

Your lifetime efficiency doesn't tell us anything about recent behavior. Even just looking at the "Current Trip" view would be more useful. I'd still recommend trying my suggestion to calculate miles per reported battery percentage. The only other DIY thing that would be useful would be to buy or find somebody with the scan tool that can report battery health.
