Range collapse

[Thesnowback]

My 23GTPE takes a good hit on range in the Michigan winter. So far this year has been fairly mild with lowest temp about 10F, but 20’s and 30’s seem more common this year so far. I schedule pre-condition my car in the garage before I leave in the mornings and the GOM tells me fantasy ranges of about 230miles. Short 12 miles trip to office where the car sits outside all day and when I leave to come home the GOM says 170miles. Monster reduction in GOM while the car sits outside in freezing weather (unplugged).

This forum has been a great help at reducing anxiety about my battery. Read the links provided and surf around the site from time to time. It’ll help with any MME buyers remorse for sure. And remember what the “G” stands for in GOM.

The GOM summary : ignore it and really do not use it to diagnose the health of your car.
For the times when you need a range estimate, unfortunately it takes some manual calculations to use the GOM effectively on the next segment of your trip.

Everyone is telling him about winter range. He has had his car for 2 years. I’m sure he knows about winter range.

Yep. I suspect this post had nothing to do with winter range and everything to do with "it has a start button" and/or "my interest rate is 8%" buyer's remorse.

I bought my extended range Ford Mache AWD in late January 2022 and up until now have done circa 25,000 miles. The car has been cosseted being garage every night and only charged up to 80% apart from long journeys as I was advised to do by the main dealer. Until a month ago an 80% charge was giving me roughly 210 miles increasing up to circa 250 in the summer which I was quite happy with. However a month ago I drove into London having charged the vehicle to 80% overnight giving me that 210 mile range. However when I completed the 53 mile round trip I was horrified to see that my remaining range had collapsed to only circa 95 miles. In other words a 53 mile journey had utilised 115 miles of my range. A disaster! I then carried out a reset on the mileage to factory settings which gave me a 270 mile range but having given the vehicle two full charges up to 100%, on both occasions this only gave me a real range of 140 miles. So my battery is clearly suffered some form of catastrophic failure.

This week my local Ford dealership have carried out a full diagnostic test on the battery (which they sent onto Ford )and tell me that it has 98% capacity remaining so there is nothing wrong with the battery and have effectively washed their hands of this as has the main dealer I bought the vehicle from. So I contacted the Ford customer service department who told me that it is nothing to do with them and to go back to the main dealer. So much for Ford customer service. I find this both extremely disappointing and insulting.

The car is on finance with Ford Motor credit so my dealer suggested that I seek redress from them which I am currently in the process of doing so.

So I am one very unhappy Ford Mache owner and after this experience wish that I had never purchased the vehicle in the first place and am very unlikely to ever purchase an EV again unless forced to by the government. And am very interested to see if any other owners have suffered a similar experience?

I have a 2022 GT I suddenly noticed a drop in mileage a 158 mile trip I would make with ease summer or winter suddenly became unobtainable without a charge to complete the journey. Last month car would start but wouldn’t run. It had just come home from a long trip and charged to 1000% overnight I left it ran an errand and tried again and it started and ran fine I drove a short distance and the dash lit up with every error you could think of and the car rolled to a stop, towed to Ford, the tow truck driver jumped the 12. Out battery and was able to drive it onto the flatbed. after a week of diagnosing and agreeing that it was “broken” I spoke with the dealer last night and he said they are going to replace the main battery, so we will see if my range come back up. Up until the final failure there were absolutely no error messages or hints of failure. I would certainly keep an eye on sudden range changes especially on a car you have lived with and made the same trip multiple times. All the keyboard warriors who prattle on about how stupid you are for not realizing it is cold and range always drops in winter are only partially correct. In my case I experienced a 30% range reduction when driving GOM had no idea it was going to happen, and the temperatures only dropped 10 degrees F. Keep an eye on the mileage there maybe something else going on with your car, don’t just write it off to winter.

OP already brought it to the dealership and battery was fine

Yes, and my car was perfectly fine until it died, my point was it did give me hints with reduced range but I just brushed them off as environmental reductions when in fact some far more sinister was going on. The car gave zero error messages up until the failure.

My Guess-O-Mater suddenly went wacko on my '21 extended range. I only charge to 70% and it used to read in the low 200's at 70%. Today it is reading 120 Miles. Sigh !

They might show back up to post the next “where is my adaptor” thread.

Maybe you were driving fast for a while so it updated. If you go from mostly city driving to highway driving that will happen. Colder weather will also drop the range as has been explained many times.

How come no one is recommending a OBD scanner to check the voltage difference between the cells.

I know ford said it was 98% but I don’t always trust them.

I’d scan the battery and full charge (likely what ford did) and again at around 50% charge. There could be 1 cell beginning to fail (defects happen) and dropping the range considerably.

Because it was 8c/46f, at 70% state of charge. Additionally, the OP said the GOM displayed range dropped, and he gave no indication of what his actual range is/was.

Therefore, this is normal winter driving behavior. Every year during winter for the past 4 years there are a flood of posts about this exact topic.

If you scroll through the posts in this thread, folks have posted links to helpful sticky threads to help owners deal with winter range anxiety.

It’s the OP’s 4th winter. I think he understands the climate effect to battery.

when my 2017 Focus Electric started to fail this is exactly what i saw. 1 or 2 cells started to go and little by little the fairly accurate GOM adjusted my total range. Over the course of about 6 months it went to zero. If 1 of his cells is beginning to die the overall health of the battery will probably read fine at 100% but drain quicker that expected.

Sure, but until it fails or the state of health shows lower than the amount guaranteed by the warranty, there is literally nothing the OP can do about it.


Is it possible the OPs battery is failing? Sure.

But 1 road trip in the winter and using the GOM as the measuring stick isn’t exactly proof.

Did the OP precondition?
Was the heat on?
Average speed for the trip?
Average miles/kwh?

We need more info.

And starting at 70% charge in the winter? This isn’t an exact science. Even the 70% number displayed is a “guess” by the computer.

I remember a thread a while back where the OP calculated their miles/kWh at around 1.2 and was freaking out. Took like 7 pages to realize the OP was using the % charge and dividing by miles driven. ?‍
