Mine updated this morning and it’s good to have apple or google maps on the main drivers display.

Still waiting for mine. Does it show Google Maps as a satellite image in real time and is it only when you set a Nav route?

Update done last week to 3.3 today Pivi Pro 4 update available. Downloaded all seems well.
Hud now shows map window/ direction to take which has been missing for last 6 months.
recall completed over the air very useful as dealership couldn’t fit me in.
Maps info more defined still checking what else has change. The recall update is complete but haven’t seen any changes related

Mine was in for service this week and dealer updated the software to BECM as per service action H441 without me asking. Just now upgraded to Pivi 4.0 no issues all seems good.
2 year (or my case another 20k miles) service included Pollen filter, brake fluid and alarm handset batteries!, all free of charge as part of Approved used next service free offer.. Happy Motoring!

So am I getting this right - They leave this piece of software indefinitely so u can only charge to 75% to monitor if it might thermal overload and then will the remove it again at some point in the future and give you a new battery of you one is at risk? This makes no sense to me. I mean how long are customers expected to only be able to charge it to 75% ???? Feels like they are doing tests in the wild that surely they could do in a test setting.

Received my letter today 68 plate, I do have the extended warranty, down side they can't do it till 30th August , due to staff hoildays and availability fo loan vehicles.

Many thanks for that letter, it's very helpful to know what JLR is doing elsewhere.

I haven't heard from my local service yet, I may prod them about it this week.

If the charging stops at 75% and you get the messages on the cluster, you take the car in and they fix/replace the traction battery.
The length of time of having a bad battery/risk of fire is as long as it takes you to take the car in and they fix it.

Has anyone had the H441 software update and then DC charged at a 100kW DC charger with less than 10% state of charge in the battery and seen a difference and the results?

ie

1. Is the useable capacity of the battery reduced? Does charging stop at 75% state of charge?

2. Is rate of charge reduced? Is there a maximum kW charging speed since the update?

3. Are there any side effect issues observed other than the above two points?

I was offered the update yesterday evening but didn't want to install it then and so left it until this morning . The update didn't install as there was insufficient battery though I'm not clear what battery it means.

I used the car today and did around 40 miles and tried it again (twice) but its still not installed (annoyingly).

According to Watt Cat TCU battery is at 96%; Aux Battery 13.9v and the car is 58% charged (range 138 miles). I will try and be patient but any idea what aspect is preventing the update installing please?

chicken george · Jul 2, 2023

schedule the update, that way it will keep trying until it works

groundsman · Jul 2, 2023

Thanks. I've scheduled it for tomorrow morning, once the overnight charge is done.

lnorange · Jul 2, 2023

Upgrade shown as available, first attempt failed to install, it then said it was ready to install again so I scheduled it for overnight but it didn't work. Its now disappeared and Pivi Pro is reporting its up to date at V3.3.3 with no upgrades available? 2021 HSE so its should have just worked - what now? Anyone else had this?

groundsman · Jul 3, 2023

Scheduled update failed - Good job really as the manually initiated one just installed. Car obviously was craving attention as it triggered the alarm once it as finished.

I just got my safety recall letter from JLR. Don't think the 4.0.0 update has come through yet for my 2021 model.

For those of you who have had this update, I take it none of you have had issues charging past 75%? Wondering if anyone is due to have their HV battery replaced.

marts4 · Jul 3, 2023

I just gave my local dealer a call today. They've booked me in on Friday to check for all updates (including H441) and a battery health test (due to a lot of mileage estimate/ use concerns). Shes done circa 65k miles. He said they only just recently carried out their first every battery work, which was only a couple of cells. The checks will let me know what's the deal, I'll report back if anything of note.

A normal charge? Mine updated yesterday and has charged to 100% overnight and this morning at home.
