Deep Sleep Mode - 12v battery drained dead [update: Mach-E jump started]

[eastern refugee]

I'm not sure what you mean. If you use the ABRP APP on your phone it can take into account realtime charger status while driving, but I don't believe it can get realtime status of your car's SOC. I also don't know if the APP is carplay compatible or not; I don't have an iphone.

I was more suggesting that you map out your route ahead of time with ABRP, and compare it to the plan mapped out by Ford's NAV. I would then follow @dbsb3233's suggestion and look at what's available at each charge stop to decide where you want to do longer meal stops vs shorter bio break stops. The good thing about ABRP is that you can set departure times as well, so you can schedule the stops with better meal choices for meal times. The only problem is that ABRP models the chargers as behaving themselves and charging at proper speeds without issues, which probably will not be the case. But, you can add extra time at the waypoints by overriding the departure times to compensate/add padding.

I haven't driven my MME much yet, and I haven't played with the NAV very much but I do know for sure that it treats all DCFC the same and doesn't prioritize by power. I'm not sure if there's a way to push the plan from ABRP to the NAV as waypoints, but worst case is old school typing in of waypoints by hand before you head out.

Thanks I will play with that this weekend with my iPhone on the app and navigation on the car to compare. GREAT idea. Thanks

Could be the reason. Could also explain why others had issues while driving and the car went into limp mode. They could all be related to a 12v issue. I dont know if the cheapy ebay obd2 scanners can read the 12v level but one way to know if its charging would be to see if theres an increase in voltage on 12v while plugged in vs while its just sitting.

If the 12v dies, its the same as your alternator going out since there is no other way to run the electronics in the car. So the errors you guys are seeing could be a low 12v. At this point the dealer will be able to figure that out easily. It just sucks you guys have to go through this.

Do we know if the ODB2 port stays ON when the vehicule is OFF? If so, I would let my reader plugged in, and read the value from inside my home over bluetooth.

I picked up my FE yesterday, drove it home from the dealers which is about 70 miles away with no issues. When I got it home I plugged it into our wall charger and the car was charging just fine. While home I was going through the Ford Pass App and setting it up as needed. Noticed that it was going to charge to 100% and since I am not doing a lot of driving now I want to keep the charge at about 80%, noticed the charge was at 85% so I stopped the charging from the app. All seemed fine. Later in the evening I checked the Ford Pass app again and it indicated the car was unplugged which it wasn't. But didn't think much about it and went to bed. When I got up in the morning I was going to be heading out so I started the car from Ford Pass App and the app said it was started. Went out about 10 minutes later, got in the car, stepped on the brake and pushed the start button. That is when I saw the Stop Safely Now error (but I wasn't moving) and a bunch of other areas. I noticed in the bottom of the instrument display, there was the graphic of a car with an exclamation point through it and a graphic of a battery in RED. Then I got a notification on the phone of an HEV-Hazard with the message "The powertain control system has detected that the system power supply voltage is lower than desired". Needless to say I was not very happy, since I had the car for less than 24 hours". So I checked the forum saw this thread and the issue with the 12V battery. I was a previous Tesla owner so I am familiar with this error as this happens to Teslas too. I do own a battery jumper pack, so I pulled off the 2 plastic covers in the Frunk (not fun) and connected the jumper back to the battery terminals as instructed in the owners manual. After about 5 minutes the LEDs on the Jumper Pack said the 12V was fullly charged. So I disconnected it and then changed the charge limit to 90% so that the HVB would charge. Then I let is sit for about 30 minutes. Went back out and no error messages and all was ok. Drove the car for about an hour with no issues. So it makes me think the car went into a Deep Sleep which caused the battery to get too low, but not so low that I could not get in the car. Could have the action of pausing the charge the night before caused this issue? No idea, but I guess I will find out tomorrow morning to see where things stand. I contacted the dealership and they are going to contact Ford to make them aware of the problem, but I am hoping that Ford is following this thread and will have a resolution soon.

I will update as I know more. Thanks

Thats not a great first 24 hr experience one would want to have...when was your car built? Trying to see if these issues are pre Jan 9 or occur post Jan 9 builds

Welcome to the Electric Brick Club . Sounds familiar. Since it's new and we know there's an issue with the 12v, I'd charge to 100%. Watch when it starts charging to see if it says in the Ford Pass App "charging 12v Battery"

I’m really thinking I’ll avoid setting up the app or limiting charging for a while after getting the car. Just old fashioned plug in and forget when needed. Wonder if that would avoid the issues?

 

[agoldman]

I'm really getting concerned that this car simply isn't ready to be released. If these latest software updates fix this and that's the end of it, then great. Otherwise, I'm not sure I want this aggrevation and uncertainty. It's not worth it to me. Plus, you say tesla's do this too? Is this a thing? I'm not sure I want to be in the "thing" club either way. Am I reading this situation wrong? People affected on this forum are taking this in stride, but this just sucks. It really does.

It sucks, but as one of the first to get a brand new car, built ground up, we are the guinea pigs. We are the testers. Look how other electronics have been released previously like play stations, Xbox, even that other electric car company, first year models at the beginning always have kinks. The pioneers are getting the kinks worked out so the future can be brighter. I'm taking it in stride knowing that Ford believes in their product and I will believe in them to fix it.

We really don’t know if there are 5 MME with the issue, or 50 or 1% or 10% or whatever.

I'm with you, but this one has a really bad side affect, especially this time of the year in cold states. A dead car is rough. Rougher when it's days old. I'm not cancelling my order,....yet. But watching how this plays out. Yes, it's upsetting.

 

[agoldman]

I'm not a statistician, but it does seem some of the most vocal members here have had the issue. Seems like a fairly high percentage of those few that have actually taken delivery. Not sure if that translates to the broader non-forum member market. The hope is that later builds won't be affected.

Except that not everyone who has picked up a Mach-E is on the forums here so you have no way to reliably determine the number.

Sure it could be huge (if it was I'd expect a lot more people reporting that issue here) or it could be a small percentage (keep in mind deliveries are ramping up quickly and thus as each week goes by more and more people are picking up their Mach-E's as evidenced by all the posts on here). Given that we're seeing a lot more happy "Mine's here" posts than "Mine's bricked" posts I'd speculate that its a small population of cars with the issue.

 

[agoldman]

fair enough, maybe, but it's definetly a club I'm not looking to be a member of. plus the alternatives seem even worse.

 

[DBC]

We really don’t know if there are 5 MME with the issue, or 50 or 1% or 10% or whatever.

I think it's 100% of some MME during a build period. Might be 100% of all MME. However, seems that cold weather makes it a lot more likely the problem shows up.

I was a previous Tesla owner so I am familiar with this error as this happens to Teslas too.

And pretty much every other BEV as well. What's amazing in a not good way is how every company claims they have a perfect answer. Till they don't. Ford could have at least made access to the battery terminals a lot easier but of course you don't need that because its fail safe system will never require you to jump start your MME.

The good news is that Ford is working on it. My guess is you'll have a fix in a week or two.
