It's a lot in anyone's dollars. That is retail. Wholesale is a lot less, but have to add back labour and incidentals (coolant, etc.). Yes, it probably exceeds current market value of a 5 year old cat.

This is interesting to read. My car had a traction/auxiliary battery fault last year while I was driving. It was fixed. Then I had the recall update. I had same issue again and my ipace has been at the dealer now for 4 weeks with no fix. They have changed modules and cables/wiring with the same issues. It's a 2020 amd less than 50k miles so im.still under warranty. Wonder what will happen and whether they will just replace the battery. Love my ipace but not sure whether I will keep the car If they fix it.

I think you are conflating different issues. The 12v failure will cause the computer to emit a ton of almost random error messages, including a traction battery error. If they repaired it by replacing the aux battery, then the issue was not with the traction battery. Now that you had the software update, you likely got a legitimate traction battery error and now they are servicing the battery.

The early failures (last summer/fall) had several instances of the car sitting for many weeks while JLR tried to figure out what to do. It seemed that by the start of this year, they had it more or less figured out as some of us had modules ordered relatively quickly. It seems with this new recall, they have gone back to the drawing board trying to hash out a procedure to fix these.

Oh I see. So last year I had multiple error messages including traction errors issues and the fix was quick. This time same multiple error issues but they have no idea so it seems you are right different issues but this seems like they are going back to the drawing board. They replaced modules, now cables and have no idea. Doesn't bode well. Sigh. Otherwise love the car

You might still have two unrelated issues (that say the same thing, so it gets complicated). A failure in the 12v battery causes a bunch of almost random errors that almost always include traction battery and/or gearbox error. When the voltage from the 12v battery (or the aux battery) drops, the computer while it is itself suffering from a lack of power, reads all the sensor lines who are dropping form lack of voltage and reports them as errors. If a wire harness is failing (the I-Pace had one major one fail for most of us), then the signals that the harness was bringing to the coputer will fail and you will also get incorrect error messages. If the problem is persisting, then either the module that is supposed to maintain the 12 bakery's is faulty, or the harness that connects the sensors to the compute is faulty (why they are searching for a root cause).

If, on the other hand, all you are getting is the traction battery fault (and you got the software update that looks at the traction battery more closely to report a bad cell), then you are likely needing one or more cells replaced but that does not involve chasing wire harness issues. The word "module" is unfortunately overused. A bad module can be a bad electronic box that controls something, or a bad traction battery module is part of the battery, so if they say they are replacing a module, they may mean an electronic box or they may mean part of the battery.

"On 29 February 2024, the RDC determined that for the 1 March 2018 and 31 May 2018 manufactured battery packs where these packs have multiple technical issues that could trigger thermal overload and the data for those already update vehicles clearly shows they are triggering the error states related to these technical issues, an elevated risk to safety exists on these pack that is above and beyond what was previously understood."

Note: the quote came from the timeline doc. All other docs state battery packs manufactured "between" the dates are at issue.

Ouch. Note they seem to have expanded the VIN range (used to be all SADHA now SADHC-SADHD). (edited to remove a section as I originally thought my VIN was in the range, but is actually just outside that range). We'll see if they expand the range given the multiple failures despite being outside this new range.

Actually the numeric range shrank. I used to be within the range but now not. Mine is SADHD2S17K1F75xxx

Well, that certainly sounds Iike owners of the 258 cats identified — including some of us posting here — are in for full HV battery pack replacement. IIUC they’re saying cars like mine within that VIN range that are self-limiting to 72% charge and throwing the P1B48-00 code, after having had the H441 software update, are among those “lucky winners.”

My cat is not in the VIN range but still get H484 in Topix. Also, not all cars in the range seem to be affected. So the VIN range isn’t much help, frankly.

I now have 5 flagged modules and can’t charge anywhere except at Tesla’s superchargers. 😝 My Zappy 2 throws all kinds of errors when I plug in the car, including car RDS fault. Dealer says it’s cool to keep driving though, as long as the precautions are considered.

I am in the range and in TOPIx for H484. I put in a few VINs near mine but they are either a different market or don’t exist.

Brought my car into the dealership this morning, for the second module replacement.
Now, 2 hours later, i received a call that the dealer was just told by JLR to not do any module replacements anymore, awaiting further information.

So this confirms things i guess. Hopefully a full pack replacement is offered on short term. Loading up to 72% sucks.

Is your VIN in the latest range of vehicles?

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.
