As for that iX, that's a hard no from me, I did a full inspection of a black with gaudy gold door handles while one charged on Thursday ?

Haha, I get it. That Bronze trim option is a hard no for me as well. It is possible, however, to configure a decent looking M60, at least to me.

Kinda crazy if true, I find it hard to believe they would still under spec it
I think the question is "under spec" for what requirements? What assumptions did they make about how our cars would be used? And also what constraints did they have with all of the other components of the battery system, which they couldn't change (cooling, sensors, specs for the bus carrying the current, etc)?

I'd rather have that mfgr-plate R1S sitting next to it....

Shouldn’t it be spec’d to the potential output of the pack at any given time?

All speculation, but I think thermal management is a challenge for our battery pack -- in many cases they have to model and approximate parameters. The motors can request a lot of electricity, and with a 400V system, you're going to see a lot of amperage (and heat),. Perhaps Ford did not model enough to cut things down at the very high end of how OP has been repeatedly driving.

I’d go for a R1S but I’m a bit worried about Rivian staying around, but I guess that’s just the name of the game with EVs

They are basically unobtanium unless you want to spend crazy markup, regardless of whether you think Rivian will be around to fufull your reservation 5 years from now.

Ok maybe I’ll do an order and see what happens ?

I have a R1S reservation, but I feel I'll be lucky to see it before 2025. Even in spite of that, however, their communication is still better than Ford's. :oops:

Like others have pointed out, I truly have a unique situation. I live only miles away from wide open back country roads that have 55 MPH speed limits, lots of curvy sections of roads that go on like that for miles on end, several sections of these roads have big elevation changes of over 1,000 feet in elevation in a short distance (both uphill and downhill), and then to top it off there will be 4 way stops in the middle of nowhere. So although it is safe and legal, I can see where it puts a strain on the high voltage components of the car.

Since most of my miles on the MME are from these roads (and I also have a C8 Corvette and sport bike that I have also put lots of miles on there as well) I know every turn very well. I know what speed I should enter the turn at, I know where the apex of the turn is and when I can go WOT out of the turn to get back up to the speed limit quickly. I will also come to a full stop at the 4 ways and start out normal but soon there after go WOT until I get to the speed limit, which only takes seconds. Unfortunately this has not remotely gotten old over the many years I have been riding out there and I do not see my enjoyment of this fading anytime soon even though I am going on the same roads over and over and over again.

What I did not realize is just how much fun the MME would be on these roads, and I have become addicted to the feeling of the MME vs even the C8 on these roads. In the 10 months I have owned the MME I am almost always in the MME and only take the C8 and sport bike out occasionally. I am just hoping the next 6,000 miles proves I just got another bum HVBJB or that like others have said maybe something was not installed properly the last time and that I am not back in for a routine 6,000 mile replacement of the same part.
Sounds to me like the engineers at Ford tried to save a few bucks and grossly undersized the high voltage contactors, whilst also not getting the memo that they were designing a "Mustang". You can see the same sort of design flaws with the way the heating and cooling system were designed as well.

That said Mustang or not, the user should not be able able to melt the contactors under any circumstances just by driving the vehicle hard at wide open throttle. If the vehicle allowed you to do it, particularly when there are so many sensors and smarts built into it, then it was quite literally not engineered properly period the end. For goodness sakes though if you call it a Mustang, folks are certainly going to try and drive it like one, so why in the world was the decision made to go with undersized electrical components that could only survive long term if driven by my grandmother?

At the end of the day I still love my MME and I give it the beans sometimes, but I always have this design flaw in the back of my head and I keep it to a minimum with that in mind because I don't want to deal with the nightmare of Ford dealerships servicing the vehicle.

R1S is about 2 year delivery timeframe. My July/August 2021 order still has an ETA of July/Sept 2023.

As for BMW i4 M50s... it was 12-16 month waits. I took over an order from July 2021 and it arrived late Dec 2022. I sort of declined it as I have not purchased it yet (lol). Others are getting their M50s closer to 8 months now.

A lot of my driving is back country roads with lots of turns that allow for full throttle exits. I am sure this contributes to my 6,000 mile intervals for the HVBJ. The obvious concern is that if I am going through it every 6,000 miles how long will it take a “normal” driver or a GT driver to do the same?
I drive my GTPE hard as hell with a lot of 0-50 accelerations and curves into straight aways and up and down mountain passes at high speeds and have had zero failures. After two failures I’d start looking at some other cause like DCFC events or timing of those with a hard driveor just something else in the power train or charging system. After 3 times I’m almost 100% certain there is something else going on here than the HVJB being the cause. Even in the what I believe is slim chance it’s actually three HVJBs that were the primary failure, there’s something unique in how you drive or operate. I’m curious to know what that might be?

The main problem is I have become hooked on the EV performance and driving characteristics. I spend a lot of my days off out in the country with wide open roads with lots of hairpin turns, huge elevation changes and lots of 4 way stops in the middle of nowhere. I have been known to go through 80% of a battery charge in one trip and almost every trip lasts well over 90 minutes (some are several hours). Although I am not at really high speeds, I am regularly around 55 mph and coming out of tight turns and 4 way stops I will be at WOT several times during the trip.
Hey, ya gotta drive it like ya stole it ;-)

Is there a possibility it’s a false alert? If the part is redesigned, should there be the early warning system? Would this early warning happen on a ‘23? Wasn’t there a software thing they are supposed to do after the replacement part is installed?

As I understand it even after the updated HVBJB is installed the recall software to monitor it and give advance warning of failure stays. It would seem so since my last failure I had the recall software installed and it gave me the same warning I am getting now with the same code.
