They gave me an ecosport?

Last time i got the escape.. It didnt take me anywhere, Oddly enough I traded my Ecosport in on the Mach e

Most people with this issue are living in extreme cold regions. This is the first time I heard about the same issue in Florida. Mine worked with no issues in summers and as temaratures dropped, this all started

But it is not that cold here, we will see what they Tech says. Could be a multitude of issues I am just not buying the entire cold weather excuse. I understand it not having the full range in the cold weather etc. But to just stop for no reason is driving me insane.

Seems pretty unfair you can only get a loaner from your selling dealer. I’d be pretty forceful on getting a loaner or having Ford reimburse you for a rental.

Well, as someone said, WE are not Ford's customers. We are the dealer's customers.
Ford's customers are the dealers.

I am getting charge fault errors all the time. Using 240V 50A ford default charger at home. This is making me nuts. Any of you guys know about this issue. I have a service planned this Friday but for now I have to remove/insert charger again and again throughout the night. Attaching msg center pic.

I suggest you search the forum for that since it's talked about a lot.

IIRC from other posts on the forum; the mache stops maintaining the 12V battery of the cars when the SoC of the HVB drops below 40%.

Wasn't it 15%?

I tried on one of them. Didn’t find a lot but do guide me if you know one. These faults are from default home chargers and not DC fast charging.

Trying to get some ? for solutions if you let me

I'm in the same boat. My car has bricked twice in less than 14k km. The response from Ford Canada has been terrible. "We can't help we need a diagnostic". It has been at the dealership 4 times in less than a year, why didn't they do a diagnostic? And they will do a diagnostic and then what? They will find there's no problem. The problem is that there are too many problems! Now my car is due back in to fix the front axle, and also the windshield and roof service recalls. I have never in my life been more frustrated with a car.

Yes. He’s probably thinking of how the 12V maintenance kicks in at 40% SOC of the LVB.

 

[DevSecOps]

Wasn't it 15%?

EDIT: I originally conflated HVB for LVB and didn't pay enough attention to the post being made. The 15% SOC was for the HVB and there's a post where an engineer from Ford actually said it's 12%, not 15%. Either way, I was assuming that comment was based on the LVB. I have modified my below response slightly to make up for this mistake.

The LVB normally hovers around 12.3V-12.8V even when it drops below the 40% SOC it doesn't normally engage the 12V maintenance until it gets much lower. There's quite a lot of uncertainty as to when exactly the DC/DC kicks in to maintain the LVB.

The two spikes below (12 hour snapshot) are charging and driving respectively. I monitor my 12V and record data on it every 5 seconds. I've never received a warning about LVB drain unless I force it to happen. Also, between the first spike and second it was on the charger. Keeping the car plugged in as some suggest doesn't mean the LVB will be continually fed juice from the charger, that's just flat out wrong.

You can see below where there's a couple 11V readings. This was because I approached the car with PaaK and the welcome lighting came on. The car didn't engage the DC/DC and it recovered once I walked away and it turned off.

With the technology being packed into vehicles these days, wouldn't it seem obvious that they should all have a diagnostic circuit that continually monitors the vehicle and reports any time the other modules are failing? I can't understand why a dealer should ever have to spend days diagnosing faults. Why aren't the vehicles themselves able to self-diagnosis?

As an aside, I wish my body had that capability. It would save me and my doctor a lot of trouble!

Watson, what ails me?

And if you are like me and most people. You get to keep making your payments even though you can’t use it.

I guess I don’t have it so bad in comparison

 

[ohmslaw]

Could have sworn I saw someone post that at HVB 40% SoC if not plugged in the LVB will not be maintained. OP charging seemed to regularly get vehicle below 40% without plugging in for some time.

Sorry for my ‘misinformation’

 

[Caliroute1]

It's definitely not 40%.... The misinformation in this thread is wild.

The LVB normally hovers around 12.3V-12.8V even when it drops below the 40% SOC it doesn't normally engage the 12V maintenance until it gets much lower.

I would really like to know how you are getting your information. Is this something readily available to non-tech types? I know last time in the shop that they replaced my 12v battery. I don’t see how keeping the car plugged in is going to solve the problems. I could be wrong and am more than willing to learn. I was told by the dealership to drain it every so often. As low as possible and charge it back up to get the range. I learned about how cold weather affects the range that I can completely agree with. Warmer weather my range increased. But I am not understanding why keeping the car plugged in would save the high voltage battery. Seems to me complete opposite would happen. If I am charged at my set point the car doesn’t accept any more juice. Like I said I am willing to learn but you seem to have some tools that I would love to be able to use
