Did your dealer say not to replace modules anymore in regards to the old H441 or because your pack also affected by H484??
I am asking because my car is not in H484 but I have the HV battery fault and charge only to 72% issue of the H441. I am due to give my car to dealer in a few days

EDIT: sorry just saw your reply your VIN is within the H484 recall range.

Mine is outside the range and at the dealer with the battery module on the shelf waiting to be installed. They are also changing the front motor, so they wanted to do both in the same session while they have everything opened up. They supposedly got the motor last week, so I expect the to start imminently and will report back if they continue to replace the module, of if that got put on hold.

I think as the data is collected on H441 failures it means if your car is in the VIN range and you have a module or 2 fail you may get added to H484. If you have had H441 and done loads of charges with no H441 flags then your cells are ok.

I am still in line for initial H441 (aborted attempt last month), so they have zero data on my car, but now on topix I can see 2 recalls: H441 and H484.

At this point I’m just hopelessly confused about the nuances and biding my time for JLR to issue another 47 service bulletins on this before eventually taking kitty to the vet. 🤦‍♂️ Traction battery fault, DTC and 72% limit, but still no recall notices for my VIN on Topix.

Another interpretation is that they determined that they used an incorrect procedure in manufacturing a specific set of batteries that poses a risk and they are not confident that the thermistors and software update they implemented can reliably identify faulty cells. Given this, they are asking everyone in that set to limit charging while they try to get new batteries lined up.

Given that your BECS value starts "BS" the car has had H441 installed, no faults have been found, no incorrect repair done, and the battery pack is not one of the suspect group. Your cat can purr along happy with a good traction battery pack. Just like mine.

I have no outstanding campaigns on Topix. I go in for the initial diagnosis this coming Monday for the post-441 traction battery fault. I'm told it is a quick "sit and wait" visit so they can read the codes, open a ticket and order the parts. I'll be driving with 72% max battery for a while.

Something I noticed, that I could not find any mention of it. 24V183-7640 came out March 07, 2024. It lists the upper limit serial number as 1F66525. My car is not in this range. Document 24V183-1427 came out March 12, 2024. It lists the upper limit as 1F76789. My car is within this range. These documents appear to be interpreted wrong, as to the chronological order, to when they came out, earlier in this forum.

I am confused. Does your Vin show as affected on Topix? Mine 75xxx is not

No Topix is not listing my 76XXX car as needing H484. My alarm has been sealed in longer than 5 months now.
Topix says I need the H441 - BECM SOFTWARE UPDATE Campaign Code: H441. My dealer said I did not need the update and Topix was wrong! Whom do I put my faith in at this point?
My belief is I am in the battery limit when they realize I have the alarm sealed in! I am not sure what I have to do to fix this. My car goes in this week for a leaky left rear axle and my 5th electronic key failure.

 

[MobiusPizza]

@Trielectric
I was under the impression that BS or later BECM version is after H441 update, so your signature suggests your H441 is done already. Probably the update was not flagged as completed on Topix for some reason.

 

[Pollo de muerte]

I received my diagnosis today: Modules 7 and 10 need replacement.

 

[Trielectric]

I called Jaguar USA today. I was told that my H441 installation was not completed when they installed it last July, even though I got the traction battery fault alarm in October. I am not on the list to get a new cell (or battery) until this software issue is fixed.

FWIW, the H441 warranty repair seems to be highly bureaucratic and cumbersome.

My experience yesterday is that it took about 30 minutes for the tech to read the codes and then an hour for JLR to approve the diagnosis. I had to wait until JLR responded to the service writer before I could leave. The service writher apologized for the wait, but he said this chicken dance was required by JLR to approve the repair. To be fair to JLR, this procedure may have been mandated by LG since they are ultimately on the hook and for all I know, I was actually waiting for LG to approve the repair.

Apparently I will receive an appointment from the service writher which will indicate the parts have been ordered. He told me that I could change the appointment, but he'd need to set it in order to get the parts. He also confirmed what has been posted here that the battery seals are often the hold up and not the cells themselves.

He told me this would be a 3-day repair once the car was in the shop.

That was my experience: it was the installation kit (the battery seals) that took the time. The actual repair took 3 to 4 days but the dealer kept the car to test charging to 100%, then using the car (looked like technician’s home to workshop commute) for 200 miles and recharging again to 100%; this took a further week.

I wonder if this is the "Phase 2" of the recall that the dealership told me about earlier this year, and that some internal JLR slides also referenced. I believe that 2019-2020 cars that got the very first version of the recall software ('BS') would get put into phase 2. That was my theory anyways.

 

[Ayepace]

There's a possibility that Trielectric's dealer did not complete the paperwork to claim reimbursement for performing the recall. This would show up with H441 still outstanding in TOPIx.
There's a possibility that the car got one of the early installations that LGES later stated didn't have all the correct files in the update.
We see that some vehicles got other updates to calibration files as noted in the BECS value and others did not. That may be related to the version of software installed in the BCCM or PCM. There's just no consistency in the installation of the update for 2019-2020 vehicles.

The potential for numerous variations is very high. Having consistent software in all the modules in all of the cars would have gone a long way to reducing the complexity, but JLR stance of "don't update without a known problem on this specific car" is coming back to bite them. Pivi Pro cars are less prone to this since the updates are bundled together and distributed SOTA to all of those cars.

And then there is the latest H484 recall that has no announced fix yet. Speculation is that real early production cars may get completely new batteries even if updated with the software update. Most of these are probably in Europe since the I-pace was on sale there before North America.

I saw an article that’s says there are 252 US cars on the H484 TOPIx list.

Interesting. That theory does make sense IMO.

My car has the aptly named “BS” update (how long ago did all this BS begin?) and still doesn’t appear on Topix as having any outstanding recalls, yet persists in giving me the TBF alert and limiting charge to 72%. Still holding off calling the dealer for the moment but pondering whether it’s a “recall” service appointment. Almost a philosophical question (if a car needs recall service, but isn’t listed for any open recalls… if a tree falls in the forest, etc.)

If your car is throwing the TBF message, then you are expected to get a diagnosis. I assume you had at last one of the recalls (H441 and when applicable, a later one) done and that recall software is doing its job in notifying you it detected one or more bad cells. This won't show up on TOPIX since it has no way of knowing if you have a bad cell, and if the recall software was done, then you have no new recall notices. If you think you car is among the few that are part of this new recall that might end up with a whole new battery then there is an argument to waiting, but otherwise, there is no argument to waiting as the only solution today is for you to have the flagged cells replaced, unless you prefer being limited to 72% capacity .
