Nothing scientific here, but here are my observations post-update:

1) no problem charging to 100%
2) charging seems slower than before
3) range estimates seem both less accurate and more conservative than before

I typically drive <15 miles a day so I’m not too worried about it.

I just charged up to 92% and only went up to 198 miles. At approx 14 mph I would have only got 212 total miles. Quite a drop from previously average of 255. Disappointed.

give It time. Mine did the same right after the update and now it’s back to ~260 or so after driving a few hundred miles.
 
I finally got my I-Pace back end of June after over 2months waiting for the wiring harness to be replaced, they also replaced the two 12v batteries and applied the recall. They had charged to 100% and I was able to completely charge a few days later though with the erratic dips that others have seen:

Drove around for a few days and got the car down to ~30% before heading out of town for a week. When I got home I charged for about an hour before heading to work with a very flat charge rate:

When I got home I plugged in to charge over night and again got a very flat charge rate issue being this time the car said its charge completed at 94% unplugged and replugged the charger but still wouldn’t attempt to top off the battery at charge complete. I’ll plug in after work and see where it stops tonight:

And I just turned on to drive to work:

this has happened to me a few times. Turn off the car, go inside, wait about 10 minutes and try again. In My experience it’ll work just fine

…it is frustrating though that this has happened to me 3x and the dealer can’t seem to figure out what’s wrong with it

Not what you want to see after 2 months in the shop! I recall the disappointment and the loss of trust after having several issues back to back, and I got that message once on a long trip after charging. Fortunately it cleared and never came back (1 year and counting), so I assumed it was a wonky ground on the charger or something. That all has been a while now, so the pleasure and trust of driving the car has returned. I hope it is not the battery, but that may be the result of the software update actually detecting an issue with the battery?

I still trust the car just really disappointing to see it after the long stretch of not having the joy of driving it. Drove it to work anyway and everything was working fine, just had the warning indicator.

I am thinking this is really the software doing its job and this is the message we see to get it to the shop for further diagnostics. The fact that 23iPace has had it several times since the recall and the dealer can't diagnose it plays to the fact that Jaguar is just collecting info on for the recall at this point and hasn't decided the full fix yet.

let me clarify … I’ve had it several times, all BEFORE the recall. I don’t think this message is related to the recall at all.

at first I thought it was the 12v battery, but considering I’ve driven the car several months since it first happened, I think it’s safe to rule that out (as the dealer already has).

my experience with this warning light has been:
  • Feb 2023 - dealer said it’s probably nothing, flashed the software
  • May 2023 - dealer couldn’t figure it out, said to bring it back if it happens again
  • july 2023 - happened for a third time, haven’t had a chance to take it in yet (I did take it in after this happened for the recall and cabin air filter, but couldn’t drop it off for them to diagnose).

…the Feb and May times were after it had charged at home, but the July instance was while I was out running errands and the car wasn’t plugged in at all.

…each time this has happened, I just go inside and wait 10 minutes and then the car works perfectly fine, and the message doesn’t return for several months it seems

I plan on taking it back in soon to hopefully get this addressed finally. If anyone has had this issue and knows what it might be, please let me know

Ah, sorry I made a quick assumption without looking into your past posts more closely. In the almost 5 years with driving over 50k miles, I had never seen the error popup until April.
 
Anytime a fault message appears it is important to have a code reader scan all modules before going through 4 stop and restart cycles. Fault codes are stored but temporary conditions may clear the codes if they don't recur within 4 or 5 starts.

Interesting. I really wish the code would be stored longer because often times it isn’t practical to get the car to the dealer that quickly, especially because they usually don’t have a loaner car available for at least a few days.

I have a regular obd2 scanner. I assume that won’t work for capturing the fault codes?
 
Drove ~14mi to work without issue except the yellow warning message. Parked all day locked got back in turned on and warning still there. Got home with 84% battery so figured I’d plug in to see what happens, instantly goes to charge complete. So I’m going to go with my original thought of this is the new software doing it’s job and found a red flag so it’s limit my charging. I’ll see if I can get it bellow 75% tomorrow and then try charging again to see what happens.

is the stitching above your screen factory or aftermarket?
 
Just looked through the 'H441 - Questions & Answers' PDF linked on the first post and question 3 confirms my thoughts on the traction battery fault detected warning:

Question 3
How would the customer become aware of potentially having this concern?
Answer
Where there is a detected HV battery issue, an Instrument Panel Cluster warning such as 'Traction Battery Fault' and 'Stop Safely Battery Fault' may be displayed. In extreme cases a popping sound and burning smell may be experienced. Smoke and potentially flames may be seen.
 
Got down to 54% and plugged in to charge. This time the car started charging right away and just stopped charging at 72%…
