My AC is taking a wee bit longer to generate cold air. Nothing terrible but noticeable.

Same here. I hadn't thought to connect H441 with the AC but that makes sense.

Right now roughly a quarter of respondents to the poll have indicated that they have restrictions on their charging. Extrapolating to the 6500 or so I-Paces sold in the US would seem to indicate that JRL has roughly 1625 I-Pace batteries that will need some form of repair/replacement. That is a huge undertaking for a small company. Given that my dealer has 2-3 EV qualified technicians across their 3 locations.......this is not looking good.

While sympathetic to those waiting for battery/module replacements, a simple evaluation of sampling techniques and polling science is necessary.
Only 13 forum members have indicated a battery issue uncovered by H441 (while 36 have indicated no problem). This could be looked at as 13/49 or 26.5%, but this is not valid. The sample is skewed towards those reporting a problem since respondents tend to report postive events or problems rather than non-events.

Another way of looking at it is how many forum members do we have? Maybe 250 active members. Assuming a member would report a problem if it occurred, rather than being embarrassed to admit they have a problem, then this becomes 13/250 or 5% (that would be 338/6500).

Observationally, forum members tend to more frequently sign up to complain about problems, thus this 5% level becomes more of an upper limit.

Based on 8 fires attributed to bad batteries in the US, and expecting JLR to be very liberal in diagnosing and remedying such potential problems, a couple of hundred "possibly" fire causing batteries is not unrealistic. That's maybe 2 battery/module replacements per dealership - not a tremendous burden. The bigger issue, is getting these replacement modules/batteries from LG.

My module is at the dealer, however we are now waiting on other parts/tools for the repair. I guess Jaguar engineers called my dealer the other day to say these other times were needed to do the work.

I would be interested in seeing a breakdown by model year as well. I find it odd that they can't trace the issue to specific modules. Or perhaps the flaw in the cell manufacturing equipment did not appear in every cell that was output? Given that GM replaced every battery, that seems to be the most likely option. With the great production volume, I wonder if Jaguar is the limiting factor in the speed of module/pack replacement. I'm sure the cell vendor is pumping a substantially larger quantity of these cells now as compared to when they were originally manufactured.

Quick update: Car was charging at less than 2kW/hr, making the car completely unusable. Had dropped it off at the dealership in Connecticut. Just heard from them that they have 3 more cars with same issues.

4 cars with slow charging speeds. The technician is unable to figure out why this is happening after H441 update.

I finally had a conversation with Jag USA about my car which has been at the dealer for almost 3 weeks. They said my car can only be charged to 72%, and that it has to be charged outside until it can be repaired. My charger is in the garage of course. I really didn't feel like driving an hour each way to pick up a car that I can't safely charge, so they're keeping the car until it can be repaired. They wouldn't give me a repair date other than "October." I did change my vote in the survey to reflect my battery restriction.

I feel like like I wrote this. Same problem. I should of kept the loaner.

If they can't trace it to a bad lot, then it is likely possible in every lot (so a manufacturing method or QC test defect). They must have done some statistical analysis to estimate the likelihood of an issue and decided that the software can weed out most of the bad ones without having to recall all batteries.

Didn't GM go the full replacement route because software couldn't identify the faulty cells?

I picked my car up this past Saturday, using the level 1 charger is definitely a humbling experience...

I did get an update from my service department today, still no info on the new software but Jaguar techs wants to replace the BECM as a first step. They ordered the part and will let me know when it comes in.

hi, any updates on your part? I am waiting on a Tk420033.
have had the car for two weeks and it’s been in the shop longer than I’ve owned it.

Nothing yet, last Friday I reported a new behavior to the service manager and was hoping for a parts update Monday/Tuesday, so will probably reach out again tomorrow.

For the new behavior, it seems that the battery percentage/range drops off faster than I’m used to based on my almost 5 years driving with over 55000miles. Keep in mind I’m one of the posters that have been able to go over 300miles on a charge though the GOM maxes out at like 282, I could drive several miles before range would start to decrease. Limited to 72% GOM shows 184miles or 255miles if extrapolating out to 100%. My commute to work is 13-14miles one way and in the past I would only consume maybe 10miles of range. Now I’m losing 18-19miles even though my efficiency is showing 25-30kWh/100miles. Part of me thinks some of this range lose is actually due to losing more battery temp over night being parked outside with only level 1 charging vs level 2 charging sheltered inside the garage.

It also seems to get worse the lower the battery gets. When I’m in the 30’s for percentage it almost seems like I’m losing 1% per mile. One night I drove 11miles and lost 22miles on the GOM. When I pulled into my driveway, parked and turned off the car it was showing 82miles at 32%. Before I could open the door the percentage dropped to 31% and by the time I got out to plug in the level 1 charger it dropped another point and showed 79miles at 30%. HVAC is off in all cases.

 

[CReeves]

Oh wow. Are they giving you any idea of how long the parts are taking? Mine isn’t drivable because they said when it’s out of charge, it won’t be chargeable without the new charging module. Currently with a rental.

 

[usarcher]

No idea on the other parts yet they said they were in transit though. Just had another new experience after using a 25kW level 3 charger that I’ve been using once a week to help offset the slow level 1 charging at home. Charged from 51% to 72%, car stopped charging, and I got out to hange the charging cable back up. Got back in the car turned on and was met by a red warning with beeping. Car would not go into gear. Called my wife to come get our son. I tried a few more times to see if I could at least get to back up away from the building but kept getting the red error lights with beeping.

After a few minutes car turned on normally with just the yellow traction fault warning, so I backed up to a further parking spot. Wife showed up and got our son and I’m walking around letting the battery cool off for a bit as I’m guessing the level 3 charging must have pushed the battery to a warmer state though it is only 63F outside with drizzle and I charged here two days ago when it was over 70F and sun.

 

[Scufflegrit]

Two weeks ago the dealer told me they would have the parts to fix my battery in 6-9 business days. Yesterday they said they now had no ETA for the parts. The dealer has had my car for over 5 weeks now. I can't believe JLR didn't have their parts dept ready for this recall.

 

[usarcher]

I did make it home without issues. Interestingly my state of charge when I headed out was at 73% instead of 72%. On all my previous charges there I had manually stopped charging before getting to 72%. I wonder if the software didn’t properly shutdown charging soon enough so with the heat from the faster charging plus getting to 73% triggered something in the software to throw the red warning and not allow the car to go into gear.

Just had another new experience after using a 25kW level 3 charger ...

I was charging last night at a 350kw at an Electrify America Station. I charged to 100%. I disconected the cable, got back in the car and started it. It gave me the high voltage alarm for a few seconds then cleared. Drove home with no other issues. I had 6 miles left on the guessometer as expected.

Same here, when I got the error, I locked the car and went for walk for about 16 min so the system would reset. Then I got back and all been good for the past few weeks.

H441 installed on June 21st.
Battery issue appeared on August 6th, just shy of 7 weeks and approximately 2,300 miles.
Car currently has 57k miles.

Wanted to add my kitty to the list with "traction battery fault detected"

Update performed August 16th. Charged 5 times since then to 100%. GoM ranges at 100% were 225, 282, 287, 282, 275.

"Traction battery fault detect. Drive with caution" popped up Oct 1st on the way back from a walk - battery was charged 9/28 overnight to 100%, so probably around 90% charge at the time.

Didn't panic since I had a scheduled appointment at dealership on Oct 5th for state inspection and a couple of cosmetic issues. Told them about the warning message. Picked car up on the Saturday (Oct 7th), was told not to worry, new software update to be released by end of month, they'd let me know when it was available.

Ran the battery down to 19% yesterday, plugged in as usual late at night. This morning found charging had stopped at 72% earlier this morning.

So, dealership looked over car last week, says nothing to worry about, wait for new software update. Is this as false alarm? I had assumed the H441 update was monitoring the battery during charging looking for a fault - guess not.

Anyway, one more added to the list of charging restrictions after the update.

 

[Brendon]

@Qtown charger For what it's worth, there is speculation out that the new software ('BT-') is now available. A screenshot of it in action is floating around the UK forums. Might want to inquire with your dealer.

 

[Topdown500]

The new software might be to correct loading issues of the previous version and will not reverse the H441 warning. Once H441 identifies a module problem the dealer needs to interrogate each module to check the status and replace module(s) or if many the complete battery.
