'24 Nautilus major issue poll #1 - Do you have a problem with the battery?

[swindler]

My Delran Battery Tender takes 12-18 hours to bring the Nautilus up to a full charge. It only goes to green when peak voltage is detected and then it goes into the trickle mode.

When used regularly on my Mustang I got a full 10 years out of an Optima Red top battery! The only reason I had to replace it was the neg battery post corroded off…lol.

The tender cannot determine if the 'full charge' is equal to the 'brand new' charge capability of the battery. As you said, only that the full voltage was reached. Like your 5 year-old phone, it will charge to 100%, but still only half it's initial charge, or perhaps even less. Time to charge isn't really a factor, as the battery's internal resistance will be higher, causing is to charge slower.

We had one battery death, with the vehicle sending a DSM only 90 minutes after being driven. Although it seemed fine for about a month after being jumped, when we finally brought it in and had it tested the battery failed. I think you should have it tested after every event. I have a CCA tester which provides a fairly accurate indication of it's charge capacity.

I definitely agree that you should have the battery checked by the dealer after every event (whether you or Lincoln jumps). When I took my Nauti in for the software updates they always do an inspection (brake pad thickness, battery, etc) but do not know how they actually test the battery.

From what I read here and elsewhere, the do not start deep sleeps almosrt always happen after a recent drive and not from sitting for extended times. I conclude this is some software bug and not fobs being close, etc. After 24B54, I notice a definite longer lag time for the infotainment to get up after it had sat over a week.

You guys have good advice and I’ll keep it in mind next time it hits DSM. The 2 events were about 4 months apart, and each time the jump pack immediately woke it up. Leads me to believe the battery wasn’t compromised too badly.

When we bring it in for service, I will mention the DSM events and make sure they check the battery.

As of today, our car is toast. It sits in a garage all day. The temperature never goes below 58 degrees. It never really gets rained on. It never gets frozen. I can charge the battery overnight with the battery tender (charge rate = 1.25A), the green light is on (full charge) and the battery voltage is 13v right off the charger. If the car is not driven, within 8 hours the battery voltage drops to 12.2. So that's that.

It went a week after the first "Remote Features Disabled" message. Now it can only go a day. This all happened within about 10 days. The car has 5000 miles.

The car can't really be used anymore. I have a jump start box but this is silly. We will take it in and let the dealer have a whack at it. There are a few obvious things I would suspect but I'm not going to guess since it's not my problem. It really should not be particularly difficult.

That sucks. I hope you get it resolved and more importantly, you get a definitive explanation as to the cause. If you get a real explanation and solution, please come back and share what you have learned.

Good luck!

 

[gooberpeas0911]

I'm wagering on software being the root cause, and the battery is toast as a result. I hope they quickly get you back up and running!

 

[angore]

You definitely need a new battery at this point but you make no mention what software updates you have had.

I have spent time measuring voltages and see what I think are dramatic dips after doing simple actions as opening a door and popping the hood. The voltage does drop but if you leave the hood up (so not to disturb) and measure later, the voltage will recover somewhat. I find the voltage varies from 12.2 to 12.5. It never seems to get back to 12.7 or higher (supposedly near full charge). after a decent drive.

I have all the software fixes and do not see significant drops while just sitting now like I did earlier (over 0.1 v per day) The vehicle can go in the remote features disabled while fully charged after a week or so there is a time aspect as well. The deep sleep notice I had once came when voltage dropped to around 11.2V, It did start,

 

[gooberpeas0911]

I'm with Angore's opinion.

I'm up-to-date on software and just picked mine up after being parked at the airport for 2 weeks. I didn't get the 'deep sleep' message on the app, and we even dropped below freezing the last several days. Approach lights, keyless entry and tailgate worked perfectly, and it started right up. I did notice the startup chimes changed to the "woody woodpecker" (as my partner calls it) vs the symphonic chimes, and it took an extra bit for the screens to catch up with information. Otherwise it was systems as normal. I do need to put some air in the tires!

Yeah, I took resting voltage measurements every day last week. It has no capacity left. The voltage just collapses within a day. You can charge it, the battery tender says its charged, the voltage measures 13v - and then it just collapses to 12.2 in 8 hours.

My girlfriend and I love this car. We are not going to trade it in. She still has her old 2006 Honda CRV. It’s perfectly fine, leather seats, runs great. Every time I suggest we take the Honda, she says Ewww! Once you drive one of these, it’s hard to go back to an ordinary car.

We made the appointment at the dealer today. It’s going in on Monday. The service adviser listed off a bunch of recalls. I’m not sure they all apply to our vehicle. We only received a letter about the passenger side window auto reverse problem. She did mention a recall for the infotainment system software and also a camera module (possible responsible for battery drain). It sounds like they already know what to do.

Just to sure you understand this, the battery would never hold 13V. It's elevated to that because of the excess charge from just being removed from the charger. A standalone battery (no load) would easily drop to 12.8V in a couple of hours. But because the Nautilus battery is under load (and we know the Nautilus is active even when idle) it would be normal to see 12.7V and maybe even 12.6V, and that's still a full charge. Cold weather would drop that voltage further.

Personally, we haven't had any issues since an event in August (and the battery was replaced) and had really stopped taking measurements. I'll try to see what we get as another data point to the long list of measurements done by @angore and others.

Yeah, I'm with you. I know quite a bit about batteries and chargers for a variety of battery types. I used to do a lot of hobbies with Gel Cell, NiCd, NiMH and LiPo battery technologies for years and years. I've had many fancy chargers. I used to plot charge and discharge curves. I'm old, so I've been around a lot of batteries. This is the first car with an AGM. I have not seen a state of charge chart for this specific AGM. From the bit of data I did take, I feel comfortable concluding the battery is smoked.

I'm really glad they seem to have this solved based on the experience you've had.

Lol. Apparently a lot of us on this forum are old. I have a lot of depth in my battery background as well, but at work. We designed battery operated tracking equipment for heavy equipment, trailers, containers, rail, aircraft, even satellites. (No SUVs tho'.)

I hope your situation is handled. I think if you have the right dealer, they'll keep you ahead of the issues.

The local Lincoln dealer had a bad day. I told them the battery was dead on the drop off envelope. This morning at 11:41am I got the dreaded "Remote Features Disabled" message. So we know the battery voltage dropped to 12.0v in less than 24 hours. In the afternoon, we called for status. We were told the tech had a hard time programming the modules because the battery is only 70% charged. I'm not sure where they came up with that number. We told them they need to replace the battery - because it is dead. Then maybe try again to program the modules. This is kinda embarrassing for Lincoln.

They will take another whack at it tomorrow. I know it's a new car but this should not be this difficult - but it is.

 

[swindler]

They might have meant "less than 70% charged". That's the minimum level for programming modules.

If you have a new car, check for open CSPs on your Lincoln Way app, under the Service tab. I think a lot of dealers don't update these automatically as they are not mandatory.

 

[angore]

The 24B54 instructions say 50% min but attached to charger with a voltage over 12.7v

 

[demark1]

Just came across this after my own posts about a new battery today after auto stop/start failed to engage. 2nd new battery *(first for me as owner) in 3 years/just under 50k miles on my 2021 Nautilus rrecently bought used from Florida (hot weather...). We will see.. base warranty covered it.

So this AM I dropped off my 2024 Nautilus hybrid to have it ceramic coated. At 3:45 I got the dreaded message that it has entered deep sleep mode. I have 4,000 miles on this vehicle and this has never happened before. Since I don’t believe in coincidences I wonder why this happened today. I bet the detail shop has drained the battery doing their work.


I plan to drive over tomorrow and add a trickle charger to avoid any further drain.

Thoughts ?

Hi Billz. A lot of innocent possibilities. They may have left a door/doors open. Hood open (if there’s an under hood light). Hatch open. Or any of them not completely closed etc. etc.
A tech could have left the ignition on (several times) etc. etc.
Or maybe the tech was playing the audio system while working on it (yes, they shouldn’t do that).

If it has never happened before, odds are very good something like the above or similar occurred. In which case, there’s nothing to worry about.

Just take a long drive at highway speeds (20+ minutes) after you pick it up to charge the battery.

Keep us updated and good luck.

Ok, here is the update. My girlfriend was communicating with the dealer since 1) it’s her car and 2) I am just slammed at work. In a nutshell, the dealer redeemed themselves. I cannot say 100% the car is fixed. What I can say is that the invoice reads very nicely. It’s probably fixed.

Here is a summary:

“Customer states : error message on dashboard saying - battery in deep sleep mode, battery keeps draining, please check and advise.”

“5136 verified complaint. Upon inspection, found 'turn vehicle on to save battery' message displayed on the touch screen. Monitored BCM battery state of charge PID. Reads 41% _ allowed 12 volt battery to charge for several hours. State of charge only reaches 61%. Load tested battery. Fails. Replaced 12-volt battery and performed BMS reset. Charged new battery to at least 80% in order to proceed with software update recalls.”

So that’s what I was hoping for. I know the battery was dead. I have an EE degree. I just wanted them to check for themselves and confirm. I’m not sure what killed the battery (was it defective – who knows). If there are further problems, at least they applied the known fixes to correct for a possible parasitic drain.

It went in on Monday and they finished the car on Wednesday. I have no problem with the length of time it spent in the shop. I’m not sure what my girlfriend said. They were kind enough to throw in a free oil change, washed the car and dropped it off in the driveway. So they really went that extra mile to make her happy. I never would have asked for that. I just wanted them to verify the battery issue and do the applicable updates. It looks like we are in good shape.

Here are the specific services:

I too believe it is innocent. Just curious
