Deep Sleep Mode.

[Minimina08]

My Corsair is in constant deep sleep mode. Had it serviced no issues found. After talking with dealership and Lincoln it seems I don't drive enough? Suggested option is trickle down charger. I don't want a car you have to plug in. I am upset with this issue. Any one have any other suggestions. I feel I should have been told this since I don't put many miles on my vehicle. I love the Corsair, but now what do I do?

Well I always leave my fob in the vehicle, just not carrying that be ole clunky thing around.
Although there is one at home.

Do you find your FOB battery goes out quicker? I take my boss's car in for service and the tech told me never to leave fob in car. I tried to explain that to my boss but he does what he wants.

Have no idea. We have a Maverick Hybrid and a 2023 Corsair (ICE) , I have a Nautilus on order.
I just leave in car and use key pad to lock and open.

Do you know if there is away to check FOB battery status?

I did purchase a couple add ons for the Corsair don't recall all the details one covers all paint chips, door ding N/C repair. The other some electronic stuff including free replacement of FOB if lost.

No, other than pulling battery and testing it but unk of there is a tester for that size battery.

I bought my 22 used and got 2 fobs (always get 2 fobs or deduct cost off sale price). Haven't lost a FOB yet but good you got that cuz a replacement is expensive. The Audi tech just stated the FOB and ECU just communicate back and forth when fob is within range.

After a few years I'll start using the other FOB..

Also whenever Im gone for a few days or more I do move fob from vehicle.

Hi gang. Hopefully this information concerning the fob batteries and keeping the fob in the vehicle will help a bit.

Unfortunately, there is no way to check the fob battery status via the fob itself or the vehicle. However, the information display in the vehicle will give a *low fob battery warning* when the fob battery does get low.

To give a general idea: My 2018 MKZ just gave me a low fob battery warning about a month ago, for the fob I always use (original battery). So that battery lasted ~5 1/2 years of "normal" use. And I used that fob for another week or two, until the battery gave up the ghost completely and would not start the vehicle (a curiosity experiment...lol).

So until I could pick up a new fob battery (CR2450 in my case), I switched my house keys to the second fob and began using it (also the original battery). That second fob was extremely rarely used in those 5 1/2 years (less than a dozen times). In the meantime, I replaced the other fob battery, but kept using the rarely used one.
After a few weeks, the information center issued a *low fob battery warning* for that second fob...lol...even though it was rarely used previously. So I switched back to the "original" fob with the now-new battery. And believe it or not, I have had issues finding another CR2450 battery in my local home improvement and other stores (even the one I purchased was the last one Lowe's had in stock). I may have to break-down and order it through Amazon.

So take my experience for what it may be worth concerning low fob battery warnings and fob battery life.
On a related note, the two fobs for my 2007 MKZ still have the original batteries in them. So at least in my direct experience, the Intelligent Access features in our vehicles would certainly seem to decrease overall fob battery life.

Also, leaving the fob in the vehicle should not drain the vehicle battery or fob batteries in a properly working vehicle. As explained in the Owners Manual (or at least it used to be explained): After a short period of time, or a limited number of approaches to the vehicle with a fob on our person (I believe it is ~5 times in my MKZ), the vehicle Battery Management System shuts down certain ancillary features/functions, until the vehicle has been restarted. This includes disabling the fob waking the vehicle, the "Welcome/Approach" lighting functions, etc.

We can test this by approaching the vehicle with the fob in our pocket until the "Welcome Lighting" illuminates. Then walk away and wait for it to turn off. Repeat this 5-6 times, and you will (or should) eventually see that the "Welcome Lighting" will no longer illuminate when we approach.

For those who like to keep the fob in their vehicle, I would only add this one caveat: Hide it in a location which is more than ~3 feet away from the ignition switch. This is to avoid the vehicle being able to be started with the fob, in the event of a vehicle break-in.
There are other system safeguards in place to help avoid this, but better to play it safe and protect ourselves.

Hope this information helps and good luck.

They busted the back windshield to get into the car. I went to the salespeople to see what $ i could get if i sold it to them, and the salesman says, "oh Im trained in Lincolns, there is a slightly hidden manual door handle just below the(for lack of a better word) left arm, armrest, and slightly above the door pocket on the panel. " But when we got outside, they had already busted out the back window. Still quite pissed about this, it took 10 days, about 4 roadside ppl, 2 locksmiths, 3 ppl from Lincoln concierge, 2 Lincoln dealership service managers, and 9 Lincoln employees until we found one that knew about the "hidden" manual interior handle. I know one of the roadside ppl couldve reached it but the dealership said they tried everything and called 3 days later saying they couldnt get in, and that I needed to either try to cut out the back windshield or break it. (cutting it out was tried first, it wasnt possible". The new window was $475. Turns out both the keys the locksmith made were about half an inch too short (pics shown). One of these keys were cut AT the dealership. Anyway my lesson from this is 3 fold, 1.always ask for a 2nd fob when getting a new car, 2. for rare occasions talk to the SALES guys, NOT JUST the service guys, specifically ask for a sales member who is thoroughly trained in Lincolns, 3.I cant remember the 3rd i got a phone call while i was typing ill update when i remember... But now that thats solved, I almost forgot to mention.... there has been a super faint mildew smell after rain in the car ever since i bought it, . I still cant find where its coming from

Hi bllo. There are other ways to get into a vehicle which will not involve breaking a window, even if the physical key can not be used/is unavailable etc.

Although they should be aware of this, ask them to use a "slim-jim" or other auto entry (a.k.a. auto theft) device.

Keep us updated and good luck.

I drove mine over 1000 miles in a 10 day period. Then the car sat for 1 day without being driven and all remote features shut down that evening. Plus, even with all that driving it was not going into auto shut-off when I came to a stop. Dealer insists nothing wrong with battery, and said it was at 70% when I was there. 5 hours later all remote features were shut down.. can’t unlock from passenger side, “welcome” lights do not come on when approaching the vehicle at night, etc. So all the stuff we paid extra for is not functioning as it should

there is a slightly hidden manual door handle just below the (for lack of a better word) left arm, armrest, and slightly above the door pocket on the panel.

Does this apply to a 2022 Corsair? If so, I can't find it. Thanks.

Actually, auto stop not working is one of the first signs of a battery problem. My car (2023 Reserve III) had the same problem with "functions disabled to preserve battery." The dealer replaced the battery (via mobile service) and the car's fine now. I didn't even notice auto stop wasn't working until it came back after the battery was replaced.

Time to replace that battery, 70% under no load is not good (50% is dead around 12v).

Just got the same answer from Service today. Love my 2021 Corsair Reserve but hate the electrical system. I'm a senior who doesn't need this issue constantly disabling things like door locks, interior lights malfunctioning, etc. Service suggests keeping battery voltage high with a trickle charger. Well back to charging battery at least monthly or bi-weekly.

Just my view BUT...
The problem is so widespread one must know the manufacturer knows about it however they either don't know how to fix it (unlikely) or the fix is simply too costly (highly likely) and I do not expect a solution period. They can dance around but in the end it will only be solved when the buying public refused to buy their defective vehicles OR there is a class action suit but even that will not fix things. For me, I'm halfway through the factory warranty so I'll drive it and see what happens. While it certainly is frustrating and I don't like it I can live with it as long as things do not deteriorate. If they do I'll get rid of it and get something other than a Ford product knowing that all manufacturers have their own problems and doing a much better job of looking into the dependability of what I may purchase. My problem is minimized during the hot months so for now all I have is the failure of the start/stop feature which I don't like anyhow. But when winter comes I expect a return to all those other failures. Throwing a charger on periodically did correct things back in the cold weather and that's not super inconvenient but it is NOT the solution (yet I'll do it from time to time.)

My simple mind says this:
The battery is inadequate OR the charging system is inadequate OR the battery control module is inadequate OR there is a software failure driving the entire problem OR maybe ALL of these things.

Good luck!

 

[olderbudweiser]

I'm no help here, but sadly Ford rewards cost cutting with bonus and promotions. There will be no fix unless it's a safety recall forced by the government.

Just the idea a service adviser suggests one using a trickle charger is ridiculous. Who here would buy a 60-100K vehicle if the salesperson told you, Oh by the way the batteries are crap you will need to purchase a trickle charger to keep your battery charged up.

 

[C Krohn]

I’ve had my CPO Corsair for almost 2 years. I sometimes get the “system shut down to conserve battery” notification, but I haven’t had any problem with things not working. I’ve left the car unattended for as long as 2 weeks with no problem.
I sometimes have an issue with the exterior hatch release button not working, but it’s intermittent and also happens with my MKX. I’m beginning to think it has something to do with the fact that I keep my fob in the same pocket as my phone.

Car back from Spring service. Service order shows serious work to check Deep Sleep problem: FDRS hookup check for DTCs, none found, SSM 52307 not applicable as TCU, APIM and GWM all up to date, battery tested good, just needed charge, also did parasitic draw test, no draw.
So will do bi-weekly AGM charge, and maybe a sync 3 update someday will help.
Thanks to all who responded.

[Troubled car owner]

I have had the issue with my nautilus after driving for 150-200 miles. That night to goes into deep sleep mode ( while I’m asleep) and when I get up in the morning it is dead. Can’t even get in the car without the little emergency key. They have checked everything says normal even changed the battery when it had to be towed in ( again after a long drive). My car isn’t idle for too long. Just got it back yesterday and it was driven approx 40 miles and within 4 hours it was in deep sleep mode and the instructions were to go drive it. That was at 11:30 at night. It was cranked for about 15-20 minutes and it did crank this morning but it hesitated before cranking. About to go to the store now -if it cranks by the way. I talked to the service manager and he said that’s what it is supposed to do. I asked him after about 4-4 1/2 hours. He said yes. We will see.

 

[A Charles 9920]

Yes, "that's what it is supposed to do".

And an new roof on your house is supposed to leak!

 

[427 Cobrajet]

My 2023 (9155kms) is back at the dealership again, for yet another week. The lead mechanic told me he feels replacing the standard battery with the 900 cranking amp battery would solve the problem. Unfortunately Ford/Lincoln will not permit this under warranty, even thought the cost between the two batteries is within a few dollars. My vehicle has become a nuisance. Now the modem has to be replaced.

 

[MagicCarpet]

2023 Corsair here. Took the car in for its 20k mile service. No problem found with battery or systems even though its been in deep sleep mode 90% of the time since new. They say its not driven enough and blamed my radar detector that is powered by the key On circuit only. They mentioned I can replace the battery (at my charge) with a larger one. The vehicle has never left me stranded but can't say I'm impressed with its slow, under powered electrical systems.
