What has got lost in this fiasco is that the number of batteries flagged for module replacement is magnitudes greater than the number of fires.

That tells me that JLR was extremely cautious with the H441 approach, resulting in the flagging of many batteries than may or may not have been future fire hazards.

What we really need to know is the identity of vehicles involved in fires, and the details of LG's production problems.
The may never really know what they did wrong to cause the fires. Imagine of they found the issue to be that they did not control the torque of some screws that connect the modules for example, and later determined that if they were under torqued, can come lose and form a bad connection leading to a fire. It may be that by not specifying a torque value in the manufacturing work instructions, they have no record of how the bolts were torqued. It might be that how one might typically tighten a bolt turned to to be close enough most of the time, the failures are rare, but looking back at the records, they may have no way of predicting which packs may fail. Imagine if at some point, some smart person decides to start recording the torque used in the assembly in the device history record (every battery pack likely has a specific record of its journey from loose parts to assembly to shipping to the factory), then they might be more confident in predicting failures after that point. Again speculating here but the take home is they may not know exactly what the issue was, or at least not know how to identify in individual packs if they had that flaw.

Agreed, but the statistical problem is likely far more basic than that - there have been so few cars that have initiated fires that unless the smoking gun defect is immediately obvious (and probably won't be after a fire destroys the battery), the exact cause may never be identified.

I find it hard to believe that a defect associated with one manufacturing device is solely to blame since, again, the number of fires is so small compared to the number of batteries/cell that would have been processed by that device.

While JLR, and the rest of us, would be reluctant to invoke some human usage factor in the evaluation, I do wonder if one factor may be battery temp when charging i.e. immediately after a high speed extended journey, or charging in a hot climate in a sealed garage etc.
 
To answer an earlier question, I just had a new battery replacement pack installed (12/12/24 - full pack, not just some cells) in my 2019 under the H484 recall. Now restricted to 80% charging cap, before it's even out of the shop. JLR is no help. No H514 recall in Topix, or software/firmware update was requested by me. I'm currently putting up a fight and won't pick up the car until it charges the new battery to 100%...

**** yeah, and good on you ✊🏼 not everyone's situation is the same, and this nonsense has been a real aggrevation.
My car went in for a 3rd traction fault (after having "battery replacement" under 441), and the dealer gave it back to me with 50% charge because they "don't have a working charger"...

Apx 126mi with an 80mi trip home, I had to charge at the closest station to them* (because the closer stations on my trip back are typically packed/inoperable) so I arrived back with apx 35% battery.
Closest [not level 1] station is 30mins away and when I went the next day, there was a line of about 10 cars waiting on 2 chargers so I had to turn back home.

Haven't driven the POS in over 2 weeks (super convenient for the holidays) but condsidering to use the last of my charge to take this thing back to a dealership.
 
5/2024 I had the traction fault go off, and they also "replaced the battery", adding 441 to my VIN. Range was reduced to 80% without any heads-up.
8/2024 & 11/24 it was taken in for additional faults classed under 514.

To bring up something @Qtown charger mentioned in another post... I remember the second/third faults tripping on longer rides*.
One just before having to top-off at a super charger (where I felt the car studdering as if I'd run something over or caught multiple flats), another one just after* leaving a station and hitting the highway. Pulled over & called the dealer immediately, but was told I could drive but should NOT park close to other cars/homes/buildings or charge at home.
That's the Convo that made me look into the issue myself, where I found this forum. Had no real clue what was going on prior to that.

Since I bought the car in 2020, I rarely used charging stations [aside from +75mi trips so I could get back home 😂 ] because I don't have any close to home. Typically charge to 90/100% because my daily trips would bring me down to about 15/20%.

Curious if others had experienced similar situations.

Your comments are relative to your specific car which we don't know anything about and you have not provided a signature for your post to fix that problem. Every year the I-Pace changed some. If you have a question, we need to know what year your car is and what updates it has had (taken from the cars center screen settings). Thanks!

Just to be clear.

My comment had NOTHING to do with tripping the H441 battery fault warning, but whether such conditions may contribute to the likelihood of a fire if the battery is defective based on a faulty manufacturing procedure.
 
Yea... Wasn't saying that your comment had anything to do with tripping 441.
Couldn't find the thread I'd referenced, and was curious if anyone else experienced their battery faults during/after extended drives... Or even while charging.

And, I had added my info. It didn't seem to save.
Don't have any specific questions. Not even here for the love of EVs, or Jaguar... If i hadn't found this forum I wouldn't been in the dark about a lot.

I believe the traction battery warning associated with H441 is triggered after a charging session. In my case, twice on starting the car after an overnight charge.

There are other slightly differently worded "traction battery faults" associated with weak 12v batteries and/or the wiring harness issue that occur independent of charging.
 
I am guessing that the car is not updating the voltage deviation data in real time, but only during or after a charge. So it makes sense to think that the TBF is triggered during or after a charge.

View my previous post on this forum, since my last post, I have experienced 1x module replacement out of 36, and scheduled to have another replacement in February, however the last diagnostics pointed back to the last module replacement as being a fault as well.... So no real end in sight, my max range (real world) is 265km to 0%, this hasn't changed since the last module replacement, JLR will not replace the complete battery pack for whatever reason even though the state of health is measured as 72% on the original modules and only 92% on the new module they replaced last (6 weeks ago), back to being limited to 72% max charge and around 175km range.

This whole issue (limited to 72% and logged fault)
really comes up as soon as the outside temperatures are above 30c, on my car the measured battery temperature is usually around 37c when it completes its charging on a 7.2kw ac charge point. Then it runs the fans and ac to cool the battery for about 30 minutes to get the temperature down to 32c, thank goodness I don't DC charge!

Into summer now and the dealership is very busy with each car coming back every month or so for its next battery module to be replaced... So far the cars are all 2018-2019 models with issues here in South Africa.

I only ever do longer distances, usually at least 100km at a time, usually 200+km per day
