Just rx’d this as well. Appears my GOM range increased by about 70 miles. Maybe in response to the concern from ER owners complaints. Charged to 90% with 287mi forecasted.

Same here, and I guess the Update caused my default charge level to go back to 100% because I woke up to 332 miles on the GOM. Not the end of the world but I'd prefer not to go to 100% just because of a software update, @Ford Motor Company; I do like the Updates though, so thanks!

One theory on the Mach E Forum is that this particular update that impacts the GOM is using a 100% charge to reset the calculations.

How can you tell if the update installed? I've gone through the process of starting update and it goes through the preparing the update, then it just goes back to the settings screen where it says I need to update. Seems like it's not installing the update

I’m having the same issue. My Lariat hasn’t been able to update over the last two days, manual or scheduled.

I couldn’t update either, I plugged in and it updated

 

[StephenD]

Ya. Mine didn't update for a few days then I pugged it in, and it finally updated. But a few strange things. When plugged in it charged to 80% like normal, but an hour later when the update took it then charged to 100%? Preferred Charge setting didn't change? It took a few times driving to where the truck notified me of the new update. The app still doesn't reflect the new update in settings. Also had gauge light issues. I think it defaulted the gauges back to max brightness? I went to adjust but nothing happened, and the buttons were not lit up. I had to turn the headlight switch to get it to correct itself? The GOM showed ~320 after update. It has sisnce worked down a little but not nearly as bad as before update. This update seems wonky!

 

[GoGoGadgetTruck]

one non-obvious thing I've been told by someone in a position to know is that the updates are super conservative with respect to 12V battery level; if you're on a charger, it's easier for the 12V to be kept up to snuff during an update.

multiple times I've had updates fail, sometimes multiple times, only to work the first time it tries while plugged in.

I also once had an update only work after I used an AGM-aware 12V charger to charge the battery for a few hours.

We had the same result. We only charge once or twice a week because we work from home, and the first time we drove after the update our GOM actually dropped by about 20 miles, but then after our next charge (to 90%) we saw a similar increase - ours to 279 miles, slightly less than yours. Maybe we shouldn't gun it quite so often on highway on-ramps

😂😂😂But it's so much fun!

On another thread someone pointed out another great approach for the 12v battery issue: toss a trickle charger on it. They had a successful update after adding the trickle charger.

I've been having trouble receiving updates this week. It keeps failing without reason, so I chatted with Ford's support and got directed to somebody in OTA. She diagnosed it as a "low 12V battery state of charge." (She said it was a big Ford problem and that it might be covered under warranty, but no lights or errors are reported by the vehicle or in the app. This seems unlikely to be a defect to me, although it may actually be low for whatever reason. Mine was delivered in June, but maybe it doesn't charge properly.)

She then told me about the following preconditions for updating, which aren't in sync with what the app says:

• Vehicle must be stopped and in park
• The ignition must be off and all doors must be closed
• Lights must be off (she recommended "off" instead of "auto")
• The time can't be set to midnight (I changed it to 10:00pm and it still failed last night)
• If you're trying a manual update, clear the schedule first and then try it (I did to no avail)
• The parking brake must be engaged (this makes little sense to me, but I haven't tried it yet)
• The vehicle must be driven for ~30 minutes prior to the update (huh?! She confirmed it again and stated the schedule should be set for a time shortly after you drive the vehicle. I haven't tried it yet, but my theory is that the battery can't be too cold.)

She tried pushing a remote update and told me "it looks like it's working" but it didn't. The vehicle never showed anything on the screen and this morning I got the same "unable to update" notice from the schedule 10pm update. Sure enough, the same update was still available.

At this point, I think she was guessing so I'm going to throw a Battery Tender on the 12V and try again tonight.

I'm curious though — and this is something she couldn't answer — how does the 12V battery recharge? I assume it gets charged from the main battery and, if so, why would it ever be low?

I chatted with the In-Vehicle Technology team yesterday and it is beyond frustrating. They told me the can't push updates (despite what I read here) and that they don't think anything is wrong despite the fact I am on 3.5.4 and an update to 3.5.5 has been showing it needs to update since I bough the truck 3 weeks ago. I am going to call them - 833.389.0848

Yes, the 12 volt battery is an issue on this vehicle, it is been discussed at length in a number of threads in this form. There has been some success by leaving it on a 12 volt battery tender, but Ford seems to be struggling to find an actual fix for it. Just one of those design snafus that happened with new vehicle designs.

This was the first I've heard of any issues with the 12V battery. Do you have any more info on this? I've searched and found mostly random form posts on the web about problems, but no specifics are ever mentioned.

According to all evidence, the 12 volt battery is not being charged when the vehicle is connected to the EVSE. The only time it charges is when the vehicle is actually "on", when the DC to DC converter maintains it from the high voltage battery pack.

This is a rookie mistake by the design team, and is a flaw we have seen in older GM EVs as well. The problem manifests when other design teams load 12 volt accessories on the tiny little 12v battery, and it just cannot hold up when not being boosted by the high voltage pack.

Even Tesla made this mistake in earlier models, but was able to rectify it with over the air updates because it was a module controlled system. Ford's system is evidently hard relay controlled, so it is harder to address. Based on the sheer number of people that are reporting problems, however, I am sure they will do something to correct it.

Fortunately, this rookie mistake can be fixed with software.

We will see, but if it could have been fixed with a software push I believe they would have already done that.

I think there's a good chance that many of those subsystems are triggered using hardware relays. A hardware relay cannot just be reprogrammed remotely the way the more modern control modules can. If this is the case, it's going to take a hardware upgrade to fix the problem.

I of course certainly hope you are right however, and a simple push can fix this.

Just wanted to post an update. I threw a Battery Tender on the 12V and it was indeed very low. Took all night to bring it above 80%. Once it went solid green, I disconnected, closed the frunk, and ran the update. Worked on the first try.

Unfortunately, I think I was an update or two behind so this isn’t the latest with the new UI, but hopefully that will get pushed soon.

Here’s what’s running now after the update:

SYNC 4 Software Version: 22228_PRODUCT
Revision: 539

I’m pretty sure there’s no way to request the latest. I’m assuming it gets batched from HQ at certain intervals, but it would nice to be able to get the latest without waiting another X days or weeks.
