2024 Nautilus software and battery issues

[Starfish]

Does anyone know a DIY fix to get the door switches to recognize the Key Fobs? My wife is going crazy having to hit the Unlock Button on the Key Fob every time she gets into the car (rather than just touching the switch on the handle). I've heard that with the battery level at 80% SOC or more, doing a BMS reset (car in Accessory mode, headlights off, flash high-beams 5 times, then hitting the brake 3 times within 10 seconds...Battery Indicator on dash flashes 3 times...verifies Reset, turn car off and let it sit untouched (Key Fobs in Faraday box, no Lincoln Way App access, no unlock for anything) for 8 hours works...and it did once, but not now after trying a number of times...how's that for a run-on sentence!

There a full thread on this. It's certainly a bit slower response than most people like, but it seems to work okay for most. Maybe check the battery in the keyfob? Maybe try the other? Make sure the keyfob (in purse or pocket) is toward Ang close to the door when you try the handle. Sometimes, it's good to hold the button on the inside of the handle for a second or two.

There's more tips in the other thread.

Yep...been there, done all of those with no success. Dealer fixed it once, I guess I'll have to go back.

FYI, I received a 'Remote Features Disabled to Preserve Battery' message this morning on the Lincoln Way app. The vehicle hasn't been driven anywhere since 8/6 as it's still in the shop. They installed a new battery around 8/7 or maybe 8/8. Presuming the battery was charged fully at that time (?), it took 27-28 days to ebb down to the first level of safeguarding the battery charge.

I think this is reasonable. What do y'all think?

Btw, I asked and the service tech will charge the battery today.

The ultimate test is will the vehicle start. We do not know the logic (power management system) on conditions that trigger saving (voltage, time, etc.) and in extreme case the first sign of a death spiral. In my experience, just sitting is the least battery draining activity. It is interaction that causes larger drops in voltage such as opening a door, rear hatch, etc. along with driving.

With a new battery, you have one less variable. What is missing is actual data such as battery voltage to support the conclusion. Is it changing power levels at the right time? I have no concern but would be data to know.

Except one post earlier, no one has mentioned an update to BMS module itself but I see that as just a part of an overall system. All power consumption fixes so far are related to hardware subsystems: camera, VDM, and anti-lock brakes.

I charged my battery up overnight and removed the noco. The battery is now 12.6V so it must have reached full charge much earlier since voltage drops slightly from max around 12.7V quickly. It has the camera and anti-lock brake software. This test is now based upon driving some distance and now letting it sit.

These are the 24 Hybrid attachment points to jump or charge under the hood. The ground is a threaded stud. The manual image is not that clear. If you are a tall person, the hood does not open as high.

Good idea to display a proper picture of the jump points.

Thanks angore! Very helpful!

Extremely similar for the non-hybrid ICE engine, same negative post, but the positive post on the battery is under the orange plastic cover.

Latest data with all battery CSPs applied. No interaction since start of test. The closest fob is about 15 to 20 ft away through a few walls.

There is no official state of charge charts as battery mfg dependent but most agree within 10%
12.7 fully charged
12.1 50%
11.51 10%
10.50 0%


9/5 - 12.6V (within 12 hrs of being fully charged), 90% SOC
9/6 - 12.51, no interaction in last 24 hrs, 80% SOC
9/7 - 12.46, no interaction in last 24 hrs, ~75% SOC

Pardon the interjection, but what are the CSPs? Do I need them? Where can I get them?

 

[angore]

Customer Satisfaction Programs. They are usually found on the technical service bulletin web page.

Actually, the technical service information page has the bulletins listed that are provided to dealer techs as to how to address common problems and is here. These are sometimes escalated to CSPs, which then are sometimes escalated to recalls.

https://www.lincoln.com/support/service-information/

CSPs are listed on the recall page, that can be found here.

https://www.lincoln.com/support/recalls/

If you want to see every CSP assigned to that model year of Nautilus, just enter year, make, and model. Or you want to see all the active CSPs for your specific vehicle, enter your VIN. I believe the only way to see what CSPs were already applied is via dealer portals. (Although, service history may show it if it's a detailed listing.)

Thank you for the detailed explanation.

I have not seen any CSPs except for the fuel injector CSP and that disappeared after I had work done on the recall web page.

I agree that it's not exactly accurate all the time. I asked about 24C24 and 24P08 a couple of weeks ago, which both came active while my vehicle was already in the shop. Neither the recall-global or recall-VIN page had either one listed. But they said they could do 24P08, but not 24C24 — even though they're both just software. Why one but not both?

Finally today is the first time I noticed 24P08 and 24C24 (as a recall) added to the global page, but still nothing on my VIN page.

So, I purchased my 2024 Nautilus Premiere gas non hybrid 2-22-24. June 3 rd the battery died they came out to my house replaced the battery June 6 th. Then, on August 6 th the battery died again. It would not jump and would not recognize the key in the car. It would not jump with my Noco. The tow truck driver had a Noco wouldn’t jump with it and he put the heavy duty jumper on it still wouldn’t jump start. Tow to the dealer stayed there three days they replaced the battery and I picked up Aug 9 th. I’ve had a month now check the battery constantly usually stays around 12.4-12.6 volts. I feel like this car is not dependable and I constantly worry it’s going to leave me stranded.

Mid May purchase of hybrid and had no issues until car went into Deep Sleep mode while at detailer mid June. Since then, my major issue has been when the battery gets low the door entry switches will not recognize the Key Fobs (must unlock with the fob to enter). We drive mostly short trips weekly with a 2 hour round trip once or twice a week. I purchased and installed a NOCO Genius 10 maintainer and an Antigravity Battery Tracker +Plus. I have typically had to put the NOCO on once a week when the battery was getting low just to be safe. About 2 weeks ago, it all of the sudden again wouldn't recognize the Key Fobs. For the past 5 days, I have not put it on the maintainer to see what it would do (see attached graphs) I am surprised that the battery is staying up. All the upward spikes are when the car is being driven.
That said, I have a service appointment next week for the following; "Fix the door switch/fob problem (for the 2nd time), perform open bulletins; 24P08 and/or 24P08B (CRM software), 24C24 (window safety), 24P22 and/or 24P22B (ABS update), 24P07 (rear shocks) and any other DTCs as required." Bulletins 24B23 (injectors) and 24P14 (VDM update) were done mid July I may also request that the 12 volt battery is replaced. I just have a feeling that that initial Deep Sleep really impacted its life.

@Starfish

Most AGM Battery charge charts list 100% around 12.7 to 13.0 V. Your charts look like how I expect a healthy battery to work. Voltages higher than 13V indicate charging. How long are your drives?

A noco charge voltage will reach 14.8 V for AGM batteries when battery is near max charge.

Someone else posted this chart but saved it since very clear.



I did not believe the 24C24 (window safety) code been released?

 

[angore]

Voltages while sitting. The last time it phoned home per app was 9/6 at 6:54pm. Using the phone app, does not initiate a response if one believes the app.

5-Sep 12.60
6-Sep 12.51
7-Sep 12.46
8-Sep 12.44
9-Sep 12.41

I consider this good.
