POST Recall Software HVBJB Failure

[ARK]

I still don't understand when people say this. It is fine to have the software with the recall AND say to call your dealer to schedule a service visit to replace the HVBJB. There is no way they'd have to do all 20,000 cars in 6 weeks or whatever timeframe. This is the same as the roof/windshield recall, most dealers were scheduling people super far out or making them wait, etc. They didn't get all cars with the recall done in a month, they probably still have a good amount outstanding, I'd wager.

The correct approach was to stick to what seemed to be their original plan, based off the very first notice to dealers about the vehicle hold, which was to do a software update and/or parts and actually do parts. They communicate to dealers to prioritize the software updates if they cannot accommodate the full part replacement ASAP, but to schedule the part replacement visit when they bring the car in for the update. Or people wait for OTA. Then those that get a failure message from the update get priority on the fix, as Ford's opinion is obviously that not all of them are going to need replacement immediately when they get the update.

But they are not going to go be able to do everyone's car soon - some people will have to wait a long time.

Shouldn't the people that have to wait be the ones like me with say a 1/1000 chance of failure on a SR AWD versus a GTPE with say a 1/50 chance of HVBJB failure (making up the numbers)?

Otherwise, if it was like the windshield recall and a total free for all for scheduling, there would be no guarantee someone with a GT didn't have to wait until Halloween while standard range Selects and Premiums were getting scheduled before Labor Day.

If they stagger it so that people who get the Service Vehicle Soon message don't have to wait maybe beyond a couple of weeks to get an appointment, and in the meantime deal with (from what you are describing), maybe not even as major of a performance limit as I speculated, isn't that a decent approach?

I have requested they try and get the "-C" part for my car and have kindly asked for pictures of both the old HVBJB and the new part. The manager has passed along my message to the shop foreman, who is EV certified and working on my car. Hopeful they remember or care enough to accommodate.

I'm supposed to get an update in a couple of hours.

Sounds like I need to turdle my car down to your dealer next time I drop a contactor in SoCal!

I can hook you up! hahaha

Sorry to hear this happened to you Neil. I hope your dealer gets those pix and gets your car fixed quickly. ??

Stupid question of the day - How does one "open a case with Ford"?

My car has been at the dealership for two days already as it crapped out on Monday with the Powertrain and battery warnings.

Call the customer support number and ask to speak with the BVE department and they will open up a case for you. Ford needs your VIN, email, name and address and the name of the dealership.

This is the snapshot from when the failure happened, if anyone is curious.

I am a bit concerned they now won't even replace my HVBJB. They had a few DTCs when they hooked the car up. They did a Self Test and cleared them all, they all cleared as @scoopman also noted. They still went ahead and updated the CMR, CCM, IPMA, PSCM, GWM and reset SYNC a billion times... even though my car is already fully updated.

Self Test is passing... I certainly hope they aren't about to call and say it is ready for pick up because the DTCs went away!!

This is what, three failures, all within DAYS of installing Ford's software "fix"? Three is not a big number just yet, but these failures all came awfully fast after the software update. That probably means something.

It may not be "false" positives, it could be conservative predictions of failure, or just buggy software. But most likely DevSecOps is right, and this software fix should be avoided until you want to start dealing with a big service job on your Mach-E.

I plan to wait until the dealers gain some experience, and service department capacity opens up some. Maybe I'll even wait to see how the 'robust' part performs in early installations, and see if Ford perhaps replaces it with something even better.

Three almost-immediate failure messages MIGHT just be random chance, but I doubt it. No software fix for me. Not yet.

I couldn't avoid it if I'd wanted to; my GT non-PE was awaiting delivery to me at the dealer and needed the recall update before I could get it yesterday.

I'm watching this closely. Thanks, all. {Jonathan}

I have a case number. Is there a way to monitor it online anywhere?

Well, this is a cluster of fuck shit. The shop foreman called me and insisted the car is perfect. He drove it for a few miles and the DTC didn't come back. Thanks to @Mach-Lee I read for him what the workshop manual states for the DTC that was present, P0ADE, and that he has to drop the pack and check. He was clearly taking offense, just like @scoopman is experiencing, and saying the "owner's manual" is a lot different and doesn't tell you everything and he's just going by the book... I kept saying this is the explicit workshop/service manual he has access to. Put in my DTC and you'll see. "Well, it's gone now, if it comes back when you drive it some more, then I can do that. I'm just trying to protect the dealer and make sure we get paid. If I just drop the pack, Ford won't reimburse us a dime." I explain again, no dice. He says he'll try and drive aggressively tomorrow on the 73 to try and trigger it himself.

What the ever living hell. I told them to call the hotline when I dropped the car off and told him to again this time. He said they're closed now, but he'll call tomorrow and only if the DTC comes back will he call them.

Talked to the service manager, he said he'll look into it but has to go by what the shop foreman says, he knows the car better than anyone else.

Looks like you were drawing 782.8 amps when the fault happened. That's decent.

Let me preface this by saying I know you need a hvbjb and you just want your car fixed but...
If you're telling a tech how to do his job you're gonna have a bad time.

He slaps that junction block in and Ford denies the warranty claim its on his ass and his paycheck. This is probably is first experience with this issue and I doubt he spends his spare time surfing Mach-e forums to stay abreast on disgruntled events.

If they give it back just go make it fail. If it doesn't? Then happy motoring!

The instructions for P0ADE clearly state that when you get that DTC, you must replace the HVBJB.

See here, make your dealer look at their Service Manual, it was just updated.
