Safety Recall 22S41 - 2021-2022 Mach E - HVBJB Recall [high voltage battery main contactors may overheat]

[VegStang]

Be sure to contact Ford customer support and open a case which should hopefully avoid that 4 month wait. They have expedited the part for my vehicle, but yea, Im working on 3 weeks now, but it is/was a new part when the failure happened.

Sorry, but welcome to the club.

And FWIW my failure (while driving) happened in relatively cool weather, low stress driving after 13k miles, L2 charging earlier in the day, DC charging a couple weeks prior but it was limited to 50 kWh.

We got it in Feb 2021, and have 27K+ miles on it

Question that might have been answered somewhere in the 1500 posts.

when it recall notice says that WOT is an issue and can cause the “problem” does that mean flooring the car or pushing the pedal only 90% . At what point of pressing the accelerator would we think is safe.

I know, this is one more stupid post. But really I want the new more robust part.

Thanks for asking this, I had the very same question and was going to post it. I feel like the degree of acceleration I can achieve even in my Premium AWD is already quite high without hitting “the pedal to the metal” but I have wondered if WOT truly meant flooring it. I imagine it’s not a binary thing and that the bottom line is that it’s best to limit the amount of current going to the HVBJB to avoid contactor pitting and arcing. Since effects seem to be cumulative my approach will be to drive my usual conservative way and wait for the newer software before getting more spirited with the acceleration. Given that most of my driving is in and around town that should be easy.

WAIT, with? JR was shot?

This happened to us over the weekend, 120+ miles from home, we got a charge malfunction, and the "Stop safely now", while charging at an EA charge station, unable to take it out of "Park", unable to turn the vehicle off. Found the "Emergency Tow mode" in the menu, and got it towed to the nearest Ford dealer. My guess is, the car is going to sit at the dealer for 4 months, until they distribute a fix.

Sorry to hear that - did they at least give you a loaner?

Uh oh, ….

Got mine in Feb 2021 and have 23k miles on it. What could possibly go wrong, right?

Good, you’ll be the first to see if AutoNation St. Pete can fix it in a timely matter. (But seriously, hope you don’t have any issues)

Just a ticking time bomb and when it happens I hope I am close to home.

It is inevitable that Ford will have to replace the related parts at some point. Once the NTSB gets involved, they will have to. They may kick and scream that it isn't necessary, but eventually the pubic pressure and Gov will prevail. Remember Ralph Nader? And Corvairs

I am pretty sure it was not Ford that came up with the wording "not robust enough". They may have developed the wording for what makes it happen which we all know here is not necessary and it can fail without DCFC accompanied by repeated full throttle events

I also do not think the power reduction can be that great or it will cause other dangerous conditions. I once pulled out to past a transport in an old truck. Pulled out and hit the passing gear, half way by the transmission let go and started to spin, no power, brake and the transport brakes at the same time. Stuck out in the oncoming lane. I found out it is possible if everyone stays cool to have a transport beside you, one pass you on coming and you in a pickup sandwiched in the middle all on a 2way highway. All that is required is to clean your pants after it happens. Long story however if you pull out to pass and half way thru that pass you lose a great amount of power that is dangerous and can not be a solution in my opinion.

Need to see what comes but do not expect it to be drastic unless it is stage 1 of a 2 part fix.

I know this is a serious recall, but keep in mind the actual failure rate when deciding whether or not to take it on a road trip. I had a short trip yesterday with 4 hours of , ahem, "spirited" driving and 1 DCFC partial charge. I forgot how much fun it was to take a road trip in this car! Way too many times I mumbled let me pass this jerk and looked down with a silly grin at the ludicrous speed while my wife yelled at me to slow it down. Sorry for the interruption, back to engineering talk...

It does have a passing presences. Most discussions here I think are due to the fear of losing that via a software governor.

Another after repeated accelerations sitting still parked. Stop safely message sitting there parked and it won't go into gear. OK we are on it.

I believe the key is "repeated." If it happened under such typical conditions as you describe, the number of failures would be far more than 0.3% of the cars on the road. Everything built will have its limitations and it's always possible to exceed any design envelope that can been created.

Now it is down to 0.3%? Whatever all happening to vehicles that are brand new and therefore we should see no more. Fake news in my opinion based of fictions statistics.

The media release from Ford is just typical down play the problem legalize along with BS about limited to demo units. We have had failures from people that have never DCFC and are gentle on the throttle, along with people that have had multiple failures.

This problem is created through standard usage of the vehicle not some extreme use case , it really is a case of not if but when this parts fails, a failure that should have been caught with test procedures. Most manufactures have some pretty serve use case tests that all ICE engines need to pass to become production viable, whoever signed off on the suitability of this part or developed the test procedures needs to hang there head in shame.

Say what you will, but the numbers speak for themselves. The failure rate on the Bolt batteries was much, much smaller, and yet every battery in every car was or will be replaced. That's just how it works.

You can't quite compare the two like that though in my opinion. Risk of fire and hundreds of thousands in property damage and potential loss of life is a lot more of a big deal. You have to prevent that at ALL costs because the liability is insane. Versus a car breaks in someones driveway or in the Walmart parking lot in a way that just renders it non-drivable isn't that big of a deal.

Less than 300 incidences in around 100k cars is under 0.3%. I guess you'd call that fake arithmetic. You have no reason to believe it's more than that, other than you want to believe it is.

 

[kennethjk]

I thought it was only 50k cars. Most cars have been sold in the last year so yes I do expect more failures to happen.

Sure you can. It was a recall for safety, and the failure was rare, and in the case of the Bolt battery, the issue was far more rare. But that didn't change the solution, because they had to fix it in any event. Also, it seems the HV failure on the MME occurs in driving conditions, so that sounds potentially serious to me. Still I understand the statistical likelihood of either. I don't wear an asteroid helmet when I go out so it wouldn't worry me.

No hard accelerations involved in this. But it was near 100F outside.
We had made our way from Yuma to El Centro, cruising at the speed limit 70MPH.
Pulled into Electrify America change station to top it off on our way home to San Diego (120 miles to go).
We got a charge fault while charging (less than a minute in). Got into the car to move it to a different charger, saw the issue on the screen, and was unable to take it out of Park, or turn it off.
Then it hit me, we were stranded.
