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?
 
No, bbf, I certainly realize you are trying to help, and as always, you do so in a very in-depth and respectful manner.

This is at the top of my list of things that keep me up at night.

And, while I realize the importance of DEEP SLEEP, it just seems to me based on the number of dead vehicles being reported, that the software could be adjusted so that those who have new vehicles with fresh batteries are not experiencing issues. And, there are reports from people with new vehicles who have experienced DEEP SLEEP anywhere between the vehicle not being in use for a week to just overnight.

But, yes, there could be other variables concerning how much the car is driven or even driven in EV mode only (which is usually how I drive). To return from vacation to a dead vehicle is a scary scenario and it concerns me greatly that the chances of it happening are actually rather high and that perhaps Lincoln could have put more effort into educating its drivers on how to avoid it from happening. I mean, is there anything even in the manual about DEEP SLEEP prevention and optimal driving habits? It doesn't seem like anybody knows how to prevent it.

So, that is the reason for taking it up the ladder, if indeed it will do anything.

@heywardjr, if you are reading this, did you post a photo anywhere of how to hook up the trickle charger to the battery? I just opened up the hood of the vehicle to connect mine and I can't even recognize where the battery is located. I think it's under something.

Hi again NJRonbo. Forgot, I wanted to offer this possible advice and now do not want it to get lost in that mess of my previous reply 🤣: Instead of a trickle charger, which you would need to open the hood, hook up etc. at the airport, I would recommend purchasing a good vehicle battery jumper pack and putting it in the trunk.

Then when you get back from vacation, if the vehicle starts up just fine, (which I am betting it will) you are all set to go with no waste effort. However, if I am wrong, and the battery is dead, then you can remove the jumper pack from the trunk, hook it up, jump start your vehicle and be on your way.

In addition, you now have a nice battery jumper pack in your trunk for the future. Which in my opinion, may come in more handy than a trickle charger alone.
And some of the better jumper packs can also be used as "trickle chargers".

Anyway, just a thought.

Let us know how you make out and good luck.

EDIT- heywardjr's and my last replies crossed in the mail. So my reply was not meant to contradict anything he stated.

Hi Miniminia. Service Departments can and do get things wrong. And/or it can take more than one service visit to properly diagnose a complex issue. How often and how far on average do you drive?

Good luck.
 
This is so easy to address with a cheap battery trickle charger. I use it every couple of weeks to check the battery and I always notice battery level low but after the charger does its magic all is well. I never had had the error message since day one of ownership last year on my 22 GT. It's very easy to attach the battery charger wires to the battery located under the extra tire located under the back area. I run the connector there and charge up. Easily addressed. I had to do this on my 2016 Ford Fusion Hybrid as well as 2008 Ford Sport Trac. I work at home and rarely travel that much so the battery gets drawn down due to key fobs nearby, alarm system active, 3rd party cameras from the rear, CD player in the glove box, etc.

So, the trickle charger goes in the BACK battery and not the front?

I am going to have to remove the tire and find it. Thanks, Hayward.

Hi NJRonbo. There are very specific jump starting instructions in your Owners Manual. Including how to connect a trickle charger. They begin on page 364 of the PDF version. I would recommend following those instructions. Check the Index of your copy under "Jump Starting the Vehicle" for the correct pages in your copy.

I am not saying heywardjr is incorrect. Only that my advice is to always check the Owners Manual first.

I will look at the manual. Thanks for the specific reference point.

Hopefully, I will find the battery without difficulty.
 
Hi Phantom and welcome to the Lincoln Forums. No one is inferring or claiming this is always "owner error". And we have covered all the possibilities in this thread, including quite a few of the possible vehicle malfunctions.

In your case and by your desription, it is entirely possible your battery is failing (yes, it can even happen with brand new batteries), or there is some sort of parasitic drain in your vehicle which needs to be diagnosed and corrected.

So to help us troubleshoot: Out of curiosity, did you purchase your 2021 Corsair new or used? If used, how long have you owned your Corsair? And when did this issue begin to occur? If you have owned your Corsair for some time but the issue has only relatively recently begun to occur, then it is most likely a failing battery. Have you had the battery tested by a Lincoln Dealer (or even a Ford Dealer)? If not, that is the first thing that needs to be done.

Your 2021 is still within the 4 year/50,000 mile new Vehicle Warranty, correct? If yes, call and set up a service appointment to have your battery and vehicle checked. Even new batteries can fail prematurely.

And if it dies again while at home or out, have Lincoln Complementary Roadside Assistance send out help. They can usually determine if the battery is weak/failing/has a dead cell or cells etc. Then you have the diagnosis when you bring it in for service.

Either way, the correct way to address this is have your vehicle properly diagnosed and fixed by Lincoln/Ford.

Keep us updated and good luck.
Hello bbf2530 thank you for the welcoming! My car was purchased new. The issue has only recently begun to occur, I believed it to be a failing battery but took it to Ford to have it tested and they said the battery was good. I've had many issues with this vehicle from misaligned doors, power window bounce back that forced me to leave my windows down in the middle of winter in a public parking lot. The auto engine shut off at stops, stopped working, camera sensors work periodically the list goes on... Ford says the car is good but I know it is not. Reading through this forum has been very informative. I am sad to say I'm considering trading it for something else as its way too expensive of a vehicle to be plagued with issues. I love the drive, look and the cabin sanctuary is bar none, if only the kinks could be worked out. Im hesitant to trade for another Lincoln if these are common issues across board.
 
In order to refresh my memory and knowledge base, I went back to read the HUGE car manual. Under the section related to VEHICLE CARE on page 421 (this entire section starts on page 419 under VEHICLE STORAGE):

"We recommend the following options for your plug-in vehicle (PHEV):

1. Leave your vehicle plugged in. The 12 volt battery maintains power if left plugged in. However, this periodically uses electricity from the household outlet.

2. Connect a battery charger to your 12 volt battery and leave it on continuous, slow charge.

3. Disconnect the 12 volt battery. If your 12 volt battery is located in the luggage compartment, do not fully shut the luggage compartment..........(you can read the rest as I do not believe this is a realistic option)"

My interpretation is that for GT models that are not driven enough (like every 2 weeks for 20 miles or so), I would choose option 1 or 2. I can do either one and after reading this carefully will just leave my GT plugged in to the 240 volt charger all the time when home. That will trickle charge the 12 volt as well as keep the high voltage battery fully charged. I will leave the trickle charge connector hooked to my 12 volt battery under the spare tire so that I can check the voltage directly periodically, can run maintenance routines that my charger offers and in emergency can charge a dead battery quickly. Please correct me if you read this section differently. Hope this can settle this for folks who are concerned that something is wrong with the vehicle. Vehicles these days are complex, they are never really turned off (particularly the GT model and models with remote start and other remote functions).

I'll state it again. I believe the Corsair GT to be a superb vehicle and the best one I have ever owned. I have had zero issues with the car in one year of ownership. One of my best friends just took delivery at end of the year of his 22 GT and has zero issues. We both love the car and brag about it.

Hi Phantom. Sorry to hear about your vehicle issues. I understand how frustrating it can be.

Concerning the battery and "Deep Sleep Mode": The Dealer should have performed a complete load test. It takes a several hours. Do you know if they did? If they did not, and they only performed a quick battery meter test, I would have them check it again, or try another Lincoln Dealership. Or a Ford Dealership if another Lincoln Dealership is not convenient.

A weak/failing battery can cause other electrical and electronic glitches, such as your Auto-Stop-Start and camera issues. That can't be determined over the Internet, but it is a distinct possibility.

EDIT- Just concerning the Window Bounceback glitch: There is a Window Bounceback reset procedure outlined in the power windows section of the Owners Manual. Might be a good idea to copy that and keep it handy, in case it happens again. It is not something you should have to do with a properly working vehicle, but I just figure better safe than sorry.

Keep us updated and good luck.

Totally agree - if vehicle is doing that then battery is bad...no doubt in my mind or there is another module that os affecting battery management. This is why I have a trickle charger that also does a basic load test periodically. I also purchased a heavy duty load tester years ago and would suggest getting one yourself at any auto parts store. See what it says and I bet the battery fails.

And we are supposed to buy electric vehicles for all of this ? Lol. Someone made a comment somewhere that made sense. If everyone got an electric vehicle the power grid wouldn’t be able to handle it ! Then all these additional problems ? Look at Tesla…..worst reliability in the ratings. I’ll stick with gas lol. No offense to anyone that enjoys their electric vehicle. To each his own. Also like I said earlier I don’t Trust cars that drive themselves. One good glitch or the satellite they use goes down and it’s a massive pileup all over the world lol. Just my 50 cents. Upped it from two cents for inflation lmao 😂

Sorry, but no car owner, much less a Lincoln owner, should have to do any of this just to keep their car running.

Last year Ford was the second largest seller of battery electric vehicles in the country (Tesla was #1). But Ford lost money, $2.2 billion. Why? Many reasons, but quality problems are right up there. Ford allocated $4 billion for recalls and warranty claim costs. Their quality is crap right now, as we have seen in many of the threads here. At least Jim Farley realizes it and is taking steps to fix it. We shall see.

Hi gang. Those are storage instructions...For when the vehicle is being stored (and not driven) for a period of over 30 days.

Good luck.
 
Very similar situation on the Honda CRV forum. Many of the CRV owners are letting their vehicles sit for a few days, (especially during the Covid lock downs) then they drive 5 miles or so, thinking they are charging up their batteries. Then, the next week, the car won't start. Some members there are promoting keeping a battery tender connected.

Most new cars have a lot of parasitic drain...The deep sleep mode of Lincolns is to try to avoid a completely dead battery. Granted, I have never seen it, and perhaps it only affects the GTs, but Lincoln is not alone building cars that have all the electronics that new car buyers demand, yet they are trying to provide cars that start after sitting unused for a week or two for vacations, etc. This is when a battery tender can be used, but obviously not in an airport parking lot. (there are solar ones available, but I have no personal experience with them)

Hi bbf2530 thank you again for responding! Ford had my Corsair for 5 hours and said the battery test showed the battery was good. I think I will purchase a battery maintainer and see how that goes, otherwise I'll go to a Lincoln dealership. I truly believe it's a battery issue. Not sure why they say otherwise.

Thank you for the info about the bounce back. It's definitely helpful to have the information on hand. It's unfortunate that I didn't have time to look into the day it happened. I was scared of a break in and felt silly leaving my vehicle unattended with windows down in the middle of winter 😂

Yeah, but what about the car just sitting, not being stored, for a couple weeks? It's inconvenient to do all the battery maintenance, add a trickle charger, etc., especially on a luxury car. It's not realistic, and I think Ford needs to up its electrical engineering game, given that a lot of owners don't drive that much. Like for many older owners here, there are only so many trips to the Senior Center or doctor's office or 3 PM senior dinner specials at Cracker Barrel they can take in a week. 😁

So the advantage of the electric car ? Lol.

Actually it is. My other car is a BEV. Most BEVs will keep the 12v battery charged from the traction battery. You can store it for 6 months with no problems. We have a snowbird friend that does this each year.
 
Hooking a battery tender in a GM car is easy as they maintain power to the cigarette lighter sockets. I use them regularly on GM cars as it just takes a minute to connect or disconnect. The Corsair GT battery under the spare tire sounds more labor intensive. How do you hook up the semi-permanent cable? The only terminal rings that come with battery tenders are for motorcycles.

What are these battery connections under the GT front hood for? The red indicates external cable OK, black indicates not OK. Yellow label points to something OK. I assume this is how you jump start car. Is it for both giving & receiving a jump? Assume yellow label is pointing towards negative jump cable body ground spot. Can you also use for battery tender?

Page 421: Keeping the 240v charging cable attached seems like the way to go. Any disagreement? Thanks.
