H441 Battery Recall Software is Now Available

As of today, JLR published several new documents regarding the battery recall in Topix. They updated the original bulletin (attached), and also provided dealer service instructions for updating the BECM software. The customer letter and a Questions & Answers document were also published, and all are attached here. According to the QA doc, the new version of the software is now available. I also noted that the H441 service campaign is now showing for my vehicle, whereas it wasn't previously.

I have my car booked to go into the dealer on Friday, and will report back on the new version. I'm already running the very latest BECM software, so it will be interesting to see how many modules get updated.

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.

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.

They just called, Jaguar UK wants the car back to the shop so their techs can work with the dealer's EV tech to run diagnostics. I'll be keeping it parked outside until I can get it there, waiting to find out what they will do about a loaner as one wasn't available during the wiring harness work nor do they have one available currently...

Well I was pleasantly surprised to be given another First Edition I-Pace as a loaner. So I’m happy to not have to go back to gas and the only real difference is it has the white interior vs mine being black. I’ll post updates as I get them.

That is pretty close to the 75% threshold that it's supposed to limit charging to if it detects an issue. Though that is supposed to be paired with a dash light. That said, seems awfully concidental. It's like it re-learned your charging threshold as the new upward limit.

Took my '19 I Pace in today for the software install while I waited. As advertised, it took about an hour and a half. Unfortunately the service advisor came out and informed me that the car immediately threw a traction battery fault after the software was installed. They immediately put me in an Audi A5 convertible loaner and gave me an ETA of Thursday for my car to be ready. We'll see.

If they are able to rectify a battery issue (assume it is with an actual cell) within a week I think they will set a record.
I'm not even sure if Jag knows how to handle these situations yet. They haven't offered much guidance on Topix to dealers about how to handle faulty batteries last I looked.

Just had the new software installed and brought my car home last night. Charged overnight to 79%. So, I can exceed 75% still. The charging curve is a bit different from before, it’s more jagged and not at the max level as continuously. GOM says 222 miles range on 79% charge

As posted in the horrid range thread...
Official recall letter arrived today.

Reading through this thread shows that many of you ignored its text. It reads "As an extra precaution, until the recall is completed and for the following 30 days, you should avoid charging to more than 75%" (I added the bolding.) Many of you promptly charged beyond 75%.

So, I am not surprised that the GOM is wonky (more than usual). They may have some special logic built-in for those first 30 days, or they're betting existing problems are found in the first 30 days.

Guilty as charged. I read the admonition to wait 30 days, but couldn't stand the suspense when I got home from the H441 update. I had to charge it to 80%, just to know I could still do it. Charging was unrestricted, and otherwise, I saw no effects from the update (aside from the version number).

Cross posting I know but
So I don't know if this might help some people. I had the safety update applied and although I didn't get any issues with charging, I found that if I did a "spirited" acceleration burst of about 20 seconds, I lost about 50 miles on my range which never came back until I plugged back in and reset the GoM with the two pedal trick. Just plugging in didn’t fix it and the GoM never seemed to realize that the 20 seconds was an out-of-norm and not indicative of driving style long term. I called into my dealer and their EV tech said there was a new powertrain module update which helped as there had been issues with syncing between the powertrain and the battery modules. Anyway, today they updated the powertrain, and so far things look promising. I will watch it over the next few days.

No recall letter here in the UK (not surprising considering how poor JLR CS is). I read the UK letter online and it does not mention owners should limit their max SoC to 75% for 30 days. It simply states do not charge more than 75% and to charge away for building while the recall update competes (which is not long if OTA).

I was not charging when the update Installed and it did so without issue. I have subsequently charged to 100% and my max predicted range is 265 miles.

The letter does indicate that in the event of any issue being found during the update, your battery max SoC will be limited automatically to 75% and that you should book a repair.

Ok, now for the first time the car doesn't recognize my key fob. It was good Thursday when I picked it up and yesterday to drive it. This morning it opened the doors but when I hit the start button I got the "Key Fob not recognized" message. Got my spare and it worked fine. If its the battery in the fob why is it opening the doors, etc.? Hope this isn't the software install but just a weak battery in the fob. Have ordered CR2032 batteries and will replace to see if that clears this up.

Yes it is the fob battery.

Buried in workshop manual I came across a description of the fob saying it has 2 batteries. One is replaceable. The other is an internal battery (probably a capacitor like my solar watches have). The internal one gets recharged from the replaceable one.

It appears that if the replaceable one is weak, it won't charge the internal one enough but still has enough power to signal unlocking. The internal one drives the fob recognition/location logic.

It would be nice if Jaguar would issue an update to give us a weak battery warning like the owners manual claims. My old 96 Disco was better than this. So is my 16 Range Rover.

Thank you. Amazon says same day delivery on the batteries so I will update once they are received. I appreciate your continued technical expertise. You have been so MUCH MORE informative than the people at my dealership its astounding. Thank you again.

What a crazy narrative. Our I-pace took the recall like a champ. I have yet to receive any official communication about this recall except that it was completed when we picked up the car for an unrelated service. I knew about it thanks to this forum and mostly followed the recommendations. It has been more than 30 days since the update was done. At no point was I informed of any restrictions. Fortunately the car has been so close to the way it was before the update maybe a keen observer might notice a difference (and those might be normal variations that were the same as the last 3 years).

Not silly. Walmart near me had them listed but only as an online item. I do check before I go. Amazon said <4hr to deliver and was cheaper than other listings - so why not? Got enough to do all 3 fobs and my wife’s 2 for her Volvo as well.
