2024 Nautilus software and battery issues

[angore]

I have looked at many battery charge charts for AGM and they vary on SOC at lower end but most agree 10.5V is 0%. I do check while attached attached.

 

[Hugo Drivenow]

That’s a good chart. It seems everywhere I read, a fully charged battery is between 12.6 and 12.8v

I recently purchased a 2024 Lincoln Nautilis the dealer told me I was the first one in the state of Florida to take possession of the car. Within a few days they called me back to update the software for no particular reason and then within a week of that my battery went dead. I took it in for service, and it went dead again, I took it in for service another time and it continued to drain after they replaced it with a brand new battery now they’re trying to load software to monitor what’s happening to the car and the car won’t accept the software they’re trying to download into my new vehicle my car is only six weeks old I haven’t been able to drive it for three weeks. Has anybody else been having similar software and battery issues?

We’re having the same problem with our Nautilus bought late June, they replaced battery on July 9th. Once again our battery is nearly drained, it started this morning but all information is dark. Frustrated

The weather app was not updating yesterday so seeing if that goes away. Yes, I rebooted.

I also had a phone connection issue but that may have been my fault (phone BT) but got it working.

I’ve encountered the weather app not updating once. It fixed itself the next time I started the car without the need to reboot.

After the complete no-start and call for roadside assistance that I posted about last week, I am now worried this car will leave me stranded. As the NOCO Boost GB40 is not strong enough to start a 80 Ah/800 CCA battery that is "too low," I purchased a Schumacher SC1281. Its advantage is that is relies on your home's 110V circuit rather than a small built-in lithium-ion battery. My concern is magnified that after sitting overnight and hooking up the Schumacher, it indicated the battery was at 25%. I could trickle charge it at 2-5 amps or boost charge at 30 amps. After less than 10 minutes in the boost mode the charger indicated it was at 100% and went automatically into maintenance mode. I didn't drive it since Sunday. This morning, the battery is back to 35% and had to hook up the charger again.
The dealer performed the 24P14 software update which states, "In some affected vehicles, the Vehicle Dynamics Module (VDM) may stay awake and unintentionally keep the Controller Area Network (CAN) active. This can result in battery drain and a vehicle no-start condition."
So even after the software update, the battery still drains too low after a day or two of no driving. This morning the battery level was 35% after sitting two days. I can't trust this car to start when I may absolutely need it.
My 2019 Nautilus after 4 years and 3 months of ownership always started, and I traded it for the 2024 in February. Never once did this situation occur with the 2019, even if the car sat at the airport for over two weeks.
I don't mind all the Android Automotive UIX issues, I can live with those. But a brand-new car that may not start is a major design or manufacturing flaw, I don't care what anyone says. I have had a couple of dozen cars, and this is the first one I have to worry about hooking it up to a charger almost daily. Heck, I might as well have purchased a full EV!

...

When had the Schumacher SC1281 indicated it was at 100%?

Was it at 100%, then you drove it Sunday, then today (Wed) it shows 35%?

I think you need a new battery. One test is to disconnect your battery to see if it self discharges after being charged.

You're probably correct about needing a new battery -- after 6 months and 3,900 miles!
From what I have read, batteries depleting to a low state of charge around 25% to 50% will prematurely lead to battery failure. But really? On a brand-new car? Give me back my 2019.

Bad batteries are a real thing. Another major premium brand has regularly been replacing batteries (and their production is in Canada, doesn't have a trip from China).

On my wife's CR-V I had a battery replacement recently, under a year after installing a new battery. It was well within warranty - they pulled out their battery tester, got the same result as my tester, no problem replacing it. The CR-V battery was one with positive reviews, manufacturing date was recent (showed within a month of my original buy date),, simply a luck-of-the-draw.

They may have been damaged due to transit. Sitting waiting g to be shipped, improperly configured for ship, improperly configured whole being prepped for rail, etc. If I take short trips my battery drops below 12v. For a hybrid, the HV battery could dump energy into the battery. I also wonder if the charge routine is low trying to to tweek mpg.

The MKZ Hybrid battery would use it's power to charge the small battery if it needed it. Doesn't seem to be the case with the Nautilus Hybrid as it really does need additional charging monthly.

The 12V in the hybrid does get charged off the hybrid battery, but the hybrid battery isn't too large (IIRC it's around a 1.2kWh battery).

I'm not sure how the Battery Management System works, whether the BMS computer itself is powered off the main hybrid battery or off of the 12V battery. I expect some BMS SW tuning would help things in either case, though tamping down identified unintended parasitic draws, whether SW or HW-related, also needs to occur no matter what.

Anyone had their BCM reprogrammed? Did the trick on my Navigator last year when I was sure I needed a new battery. Factory battery running strong almost 2 1/2 years later from new.

But hey, must just be bad batteries.

Nobody has said it is only bad batteries.

There is one unintended parasitic drain SW update (VDM) available at dealers now, and a second unintended battery drain SW update related to the driver monitor camera was put on hold as a dealer install (not sure why, what issue they ran into). Both of those updates are "reprogramming", of the particular modules where Lincoln has found bugs, are due for a wider release as part of a Q3 software update (meaning sometime by the end of September).

Nobody knows what other software updates for battery drain are being worked, we only find out about them when an SSM is released. Maybe there's a BCM one coming, though there are many individual modules in the vehicle (multiple little computers). The '24 Nautilus "BCM" itself is actually more than one module, in different locations, from chatting with Haz and looking at diagrams he had posted in a different forum.

I hear ya. Just asking.

The overall state of play is that there have been actual battery problems, though whether they were manufacturing defects vs. sulfation due to the long transit, vs early fail due to the various unintended parasitic drains I don't know (it may well be a combination of these factors).

The one positive aspect I see is that Lincoln appears to be actively working on SW updates to fix the SW bugs once they find a particular source of drain, and has been replacing failed batteries (as they should). They don't kick out a battery drain SSM until they've debugged to the point where they can say there's an issue with a particular module, something that they can then allocate resources to fix the software on.

AGM batteries only come with a 36 month warranty and given my history with lead acids I rarely get the claimed life so not expecting 36 months from the Nauti AGM especially if it can spend a lot of time a low charge levels. I have the noco 5 for that too whenever the battery voltage gets below 12v.

But, I now have a GOOLOO GT4000 as my jumper. I was looking at the noco gb70 but this unit had slightly longer cables and standard usb c charging plus it was less expensive. It comes with an assortment of cables for input and output. It can be used as a jumper or reserve power source for 12V or usb devices (type A and C connectors).

This is more piece of mind since I would be leary of taking the Nauti out in the boonies (like for a hike where cell coverage is spotty) when the battery can deplete enough to go into battery save mode. I would not do something like camping with it without a backup.

It looks well made and came in nice packaging. The brand name may leave a negative impression for some.

Note: The 100W charge rate requires the 12V vehicle charge connection (provided) or a 100W USB-C AC charger (not included). I just used a usb-c high rate phone charger and it charged up (from 80%) quick enough. The charge rate appears where the "100W" is shown.

Irony. We've had our Reserve 2 in for the past 9 days for a few things that needed fixing, including a new battery. The loaner they gave us appears to be a Reserve 2 also, but the gas model (and Jet package).

This morning my wife went in to start the Nautilus and the battery is dead. It did manage to click the starter on the first attempt, but is completely dead now.

We got it started after some angst. They're going to swap the loaner for another loaner for us.

Still not sure when our car will be ready.
