2022 I-Pace, Enel JuiceBox Charger

Woke up this morning with the rude awakening that my car didn’t charge to 100% for our trip. I tried replugging the home charger...didn’t work. I tried the granny charger...worked for a little bit then stop. On the instrument panel, I get a message that reads: “Okay to drive with caution High Voltage System Fault Detected.” Argh! Brand new car and now this. All the while wife is upset that we are going to hit major traffic for our trip because we have to stop by Jaguar first.

I was fortunately able to drive it safely to my local dealership without a problem. The error sign popped up again when I tried to regen (not sure if this is related or a byproduct of the problem). Searches on this forum and UK forum has been in conclusive, pointing to different things. Is this a software problem or a hardware? Dealership won’t look at it until Tuesday or Wednesday next week. For now I am in a loaner GMC gas car. So frustrating!

So sorry. Sucks that even 2022s are having problems.

I know. :/

Should I tell the dealership to update my TCU and battery control module software? Read somewhere that this may the cause?

 

[Ayepace]

Isn't your dealership competent enough to be able to figure out (well use Pathfinder/TOPIx Cloud to find out) what needs to be fixed or updated?

 

[Cornea]

I sure hope so. The car has not been touched since Saturday morning drop off. They said they’ll get to it tomorrow.

Be aware that dealerships want to hear that you have a problem with a functionality of the module you want updated ... if you don't have an issue with TCU functions they'll push back (because they won't get reimbursed by JLR if there isn't an issue).

I’ll “try” to let the technician do their job and not helicopter. I’ll definitely chime if they come back and say the car is “fine” and nothing is addressed. On a side note, my wattcat and MyPace app has the following reading:

Event log: EV Charge Fault
12V battery: 12.3v
TCU battery: 98%
TCU IMEI: 015277000717683
TCU software version: L8B2-70712-AX
TCU confit code: blank


UPDATE:
Day #4 at JLR: no one has looked at the car yet. Kitty went into hibernation because of inactivity. Spoke to service department and told them I am an unhappy customer of a brand new 2022 car. Apparently there’s only 1 licensed I-Pace technician at my dealership. The wait continues...very frustrating.

I replaced the gasoline car with a Kia E-Niro loaner. It seems to be charging just fine with my JuiceBox. 🤷🏻‍♂️

Day 5 Update: "the saga continues"

The I-Pace was finally looked at--finally! Spoke to the service supervisor, who told me the I-Pace technician ran the BECM and got a message, reading "ground to earth" fault/issue. They're escalating the issue to corporate in New Jersey for further guidance. What does this mean? Has anyone experienced this?

 

[sciencegeek]

It's a good thing they're asking for help. Fingers crossed.

 

[Ayepace]

A more complete text of the message, or fault code, is needed to be able to explain it.

There are many messages possible concerning "ground to earth" (possible short circuit) of various components in the BECM, BEM (controlled by the BECM) and wiring harnesses part of the traction battery management.

 

[Cornea]

I wish I wrote down the code... hoping the problem gets identified soon.

I hope I don’t have to resort to a lemon request...wouldn’t be sure what car to get especially in this crazy climate.

Update:
Week #2 - Opened a case with JLR North America. Car is still in the dealership. Not sure what the exact problem is or when I will get my car back. Supervisor told me the car is displaying the following code: SSM74272 (hoping my recollection in the moment is correct). In reading Topix: https://static.nhtsa.gov/odi/tsbs/2019/MC-10155303-9999.pdf , I think I am stuck in Procedure B purgatory. Any one had this problem and came out positive on the other end with a healthy I-Pace?

Week #2 Update: spoke to service director at the dealership and he filled me.

• SSM74274 - fault, BECM - P0AA6 code
• JLR TA - says unplug everything, let the car reset, and replug everything and check
• car came alive without fault, serviceman drove the car and dropped the battery to 80%, L3 charged it back up and the car threw the same fault at 94-95% (note: this also happened to me at home with my L2 and trickle charger not wanting to charge past 94%...interesting!)
• JLR TA: told the dealer to order Electric Air Compressor for the HVAC and replace it. Huh? How does the AC play into this? Does it help cool the battery at a higher state of charge? Also, the cabin AC was working fine.... Hmm, the service director didn’t seem to believe this was the solution, but said he has to follow the TA engineer lead.
• now looking at 10 day wait for the parts to arrive from Brisbane Australia...the saga continues.

I'm sure someone smarter will reply, but I theorize that the battery needs some thermal management when getting close to full and a failure in the cooling system might throw a fault?

Update 3/16/21
New AC compressor was installed. Not to my surprise, the high voltage fault was not fixed. Car still does not charge past 93-94%--albeit, it did charge to 100% once. Almost a month's time in the shop wasted. Back to square one with the service department reaching out to JLR TA again for SOS.

I tried to echo that the BECM should be looked at based on my research on this and the UK forum. Maybe I am impatient, but there doesn't seem to be a sense of urgency when it comes to Jaguar fixing their marque EV.

I am beyond frustrated that I am now looking at Kia EV6 and the likes--can't believe a KIA cost >$50k! I like the BMW Ix for its range, but it's butt ugly. E-tron looks bloated. Honestly, I am not even sure what I would get in this current market.

Sigh back to waiting... Hopefully, there will be a "epiphany" soon from the service department.

I feel your pain. Mine has been almost 5 weeks in the shop for a 12v issue that was “fixed” 3 weeks earlier after another couple of weeks. I expect it back tomorrow but my trust in the car has been severely compromised. The service people are doing their best here but that only goes so far.

i also started looking at what the other options might be and was thoroughly unimpressed, so I’ll keep sticking it out with the I-Pace and hope I have some peace for a while.

 

[Ayepace]

As you can see in the bulletin, the AC compressor can be a source of the problem if they got a fault code of the flavor
P304C-xx Electric Air compressor - High Voltage Supply Circuit

Maybe this got solved but there is another fault still not resolved.

Have they shared any (all) fault codes found?

I hope your car is finally fixed. I share your sentiment regarding losing “trust” in the car.

The fault codes have not been shared with me. The only one I am aware of was the SSM74274, BECM - P0AA6 code.

 

[Cornea]

Update: the fault code is P0AA6-xx - Hybrid/EV Battery Voltage System Isolation Fault.

Insights into what this may be? Car will not charge beyond 93-94%. Is it a bad battery cell, faulty BECM software/hardware, or internal charger?
