Finally got my car back after the dealer replaced the lift gate (at their expense). Initially the car threw a traction battery fault when the update was applied, but it cleared itself after sitting at the body shop for two weeks.

Like others have reported, the GOM is showing a greatly reduced range but I'll give it time to relearn before worrying about that.

 

Adding knowledge to the community of enthusiasts:

• car went in for routine 2-yr/21K maintenance, PiviPro already updated to 4.0 via OTA on June 30th
• took a few hours to change fluids, rotate tires + realignment, change cabin filters, and check for any open recalls
• left dealership the following day, noticed software updated to 4.0.1, interesting -- this was not a true software update, but rather the updating internal certificates to match recalls performed
• still able to charge to 100% (~85kW useable), been noticing lately that sometimes (~2 occurrences) where the car would stop charging at 85% or 91-92%, if unplug and re-plug it will charge back up to 100%. This only happened after 4.0. Of note, my car has. brand new HV battery pack that was installed in May. Not thinking much of this as of now.

How long did it take to replace the battery pack? Was it in stock or did you have to wait for the parts?

Before H441 our iPace was still showing 370km at 100% charge after 4 years trouble free and 130,000km. Driving car home after recall H441 software update ‘Traction battery fault detected’ displayed. Warning repeated at every start after that and all charging stopped at 72%. Dealer diagnosed one faulty cell and said H441 update damaged the battery, which sounded odd to me. However Jaguar New Zealand installed a completely new battery under warranty, so I am happy with that but none the wiser. I have asked for the whole job report but have not received it yet.

 

So I just scanned through about 1/3 of this thread...can someone clarify without me reading the other 125 posts...the car will charge over 75% post recall, and the 75% just applies if the system senses a real problem?

On a side note, I went to visit my 2019 I Pace yesterday at the dealer. It has been broken now for several months, waiting for a new battery control module. I took it home for a couple weeks to get it cleaned up and out of the sun and do some limited driving, but then the AC failed (5th time), and it was too hot to drive so I took it back to the dealer. And then the recall happened, so hopefully they will do that when it finally gets fixed. It has been at the dealer for probably 1/4 to 1/3 of the time since 2019. I keep hoping that the next fix will finally get it sorted. It is worth so little that it is hardly worth selling, but works so little that it is hardly worth keeping. My daughter and her husband could use a free car, but saddling them with this mess seems misguided. Any thoughts people? I've been here since the beginning in April of 2019 and was an enthusiastic supporter, and love the car when it works. But when is enough enough? When you are in a hole, stop digging?

 

Yes the car will charge over 75% post recall if there is no problem detected. Several people who got the recall before getting the US recall letter did just that. The letter recommends not charging above 75% for the first 30 days after the recall update is applied.

The dealer won't have a choice about applying the recall. Once they install a new BECM they have to validate it works and the software is up-to-date. That will install the recall level of software.

There are several causes of AC failure documented in other threads. Hopefully the dealer will investigate each service bulletin on the topic.

I'd be happy to take the car off your hands for $1. That's more than you'd get over giving it to your daughter for free. 😀

 

I took my 2019 HSE in two weeks ago for the update. Received a traction battery fault message after charging it a few days later. The dealer is telling me I need 2 12 volt batteries replace at a cost of over $1,000. Said it is not covered under warranty because I did not put on 10,000 miles per year. This makes absolutely no sense to me> Why should i=I have to pay for this????

 

Something about that is wrong. Dealer replaced these on my 19 HSE at the 20,000 mile mark under warranty in 2022. Took a while to get done but they even gave me a loaner LR Discovery for a few weeks. Only thing I had to do is ironically pay for gas to fill up the loaner.

 

Call Jaguar USA.

 

Call Jaguar USA.

Thanks I will try that

 

Do what Docrwm says. There is no such language in the US warranty.

If you don't get satisfaction that way, you can replace the batteries for far less by doing the job yourself, or having a friend do it for you if you're not able to. There are instructions in 12V Battery Problems and Solutions threads.

If you don't get any satisfaction from Jaguar, try another dealer if you can. Or complain to dealership management. Lots of us on this forum have gotten free batteries under warranty. My car only had about 4,000 miles per year.

 

I got mine replaced at 17k last year in my 2020 for free under warranty. If what is being reported is true the dealer is full of something.....

 

I'm going to call my dealer tomorrow. I got the traction battery fault this morning. That was the only error. H441 was applied and the starter battery replaced 6 weeks ago. I don't think they replaced the aux battery then, but both batteries measured 12.6V-12.8V with my multi-meter today so I'm not too optimistic it's the aux battery. I haven't had any wonky range or charging issues since H441.

 

Had to take my car in for a traction battery fault about a week ago. I was literally just about to start the paperwork to buy my car and now I'm hesitant because it's frustrating that it's been in the shop.

I have been in constant communication with the service person and they let me know some interesting info, not sure if it's just them covering their ass or whatever.

As follows: they stated they finally received word from their technical team and apparently, there is another software in the works for the specific issue with my car (is it really specifically just my car?). That software is expected in mid-September. I was offered to take my car back but was told that the car will not (cannot or shouldn't be, not sure) charge above 80%, and it needs to be parked outside until the issue is resolved, which sounds like there's a risk of it going up in flames, until the new new software update around second week of September.

Sigh

There is a 2nd round of software updates scheduled for September (as I was told by a JLR technical guy through their customer service group). Not sure if this is for everyone or just those that the current update has flagged.

Sounds like the H441 software has flagged a "potential" problem with your battery. Whether it is going to spontaneously burst into flames in the coming weeks is another issue. Comparing the number of folks on these forums that the H441 update has alerted to a potential problem with the number of actual fires to date, I would suspect the update is being very conservative and highlighting cars with a possibility of a fire, rather than predicting a battery fire.

 

I haven’t called the dealer for the H441 appointment. Maybe I should wait mid September for the V2.0 version ? Anyway I need my car for a couple of journeys in the coming weeks so I am not in a hurry for it.

 

Version 3 of US recall. Says there is an update to the note about parking away from structures. The paragraph beginning "In line with..." is changed.

 

Thank you. For those of us that had H441 installed prior to v3 do you have any information on whether getting v3 is required/advised/preferable/etc.?

 

It only looks like they've issued a third version of the document at this time. No word about revised software.

 

Thanks, my mistake.

 

I had my H441 update installed this week. It took two attempts as the first time the software wouldn't install for the dealer. "Failed to update the Module" error message. I did have a low secondary battery (the brake pedal feel light had come on over the weekend). They replaced that and still no luck so a Ticket was created. Back in 2 days and the install went smoothly. I was in and out of the shop in 50 minutes. The shop in Richfield MN was very good to work with and I will go back there for sure.

I also charged last night, level 2 home charge at 32 amps. My Pepe (a vey stubborn mule) went from 48% to 100% with just some variability early in the session. And I have the highest range prediction to ever at 265 miles (ambient temp 45 F this morning). I'm optimistic that the 100% charge outcome will hold up and I'll avoid the battery issues.

Here is the log from WattCat. Interesting what difference the scale makes in perception on the early variance
.

Thanks for the post. It's interesting how (and where) the charge rate dropped around the 70% mark.

And you've passed the first hurdle. It's true that it takes a month for the battery to be totally analyzed... but a lot of people get the warning on the way home from the dealer. At least you're beyond that.

 

It takes 30-40 days for any battery module(s) to respond to the H441 software.

 

Mine has been at the dealer for 2 months. I could sign a waiver and take it, but the only parking spots away from my vehicle are under trees in the middle of a national park, so…

 

Why has the dealer had it for two months? Are they awaiting new battery cells? Did they give you an ETA?

 

Waivers are an option? That's great to hear ... I'd sign a waiver in a heartbeat and keep SoC between 20 and 70% ...

 

Speaking of Chevrolet, they sure put JLR to shame with the fix for these LG batteries. A friend of mine with a fairly-new Bolt was offered a replacement car (one MY newer) which he opted for in lieu of the replacement battery.

 

My sister has had her Bolt locked at 80% for over a year. They got a recent software upgrade that will monitor the battery and if no errors come up in 10k km, the battery will be declared ok and stye will get the 100% range back. Nothing else has been offered for having 80% for over a year.

 

Enhanced software was expected to be released back on October 9 for MY20- and early November for MY21+.

Another interesting doc is from a shop foreman conference call.

Interesting documents (though crammed with acronyms!) particularly as my car was dropped off at the dealer last Monday with the Traction Battery Fault and I’m awaiting news.

It appears from the document that the dealer may (is not mandated) to hold onto the car until the parts arrive and the repair is carried out. Yet it seems that many owners are left without their car for weeks/months.

 

My dealer verified I had the Traction Battery Fault alarm, then told me they had filed a report with Jaguar and were waiting for a reply . Gave me back my Key and told me to watch my charging. The newest info states December 15, 2023 is when Jaguar will be sending out info for the newest software.

 

As of last Saturday, I tell people I use to drive an I-Pace First Edition, but now I drive an I-Pace Limited Edition.

 

Another car to add to the long list of battery recall because of fire : Jeep 4xe. I don't know if LG is once again involved here.

 

I got H441 BS version bank in August. No issues with numerous L2 and L3 charging since. No outstanding recalls since then.

I took my cat to the vet last week for a cold weather camera issue. I got it back today and found, undocumented, BECM was updated to BV version.

This resets my cautious nail biting as charging reaches 72%. I thought I was in the clear with a good battery.

Further confirmation that "phase 2" of the update for 2019-2020 cars is now in play.
I was at the dealer two months ago and had to beg and plead to get updates from BS to BV. They had to push on JLR to allow it ahead of the planned phase 2 rollout, and it required a week just to get approval.

 

BV only effective if BS was not installed properly. If BS. was installed properly BV is just an update and will indicate if you have a failed module just as BS would.

 

Seeing as there have now been 4 revisions of the software (BS, BT, BU, BV), I suspect it's safe to assume that numerous fixes and improvements have likely been made between BS and BV.
