⚡️ Home Charging Issues after Software Update? (Tracking Thread)

[Bolt1323]

Ok, that appears to be a different part. Hopefully it works for you.

Update: didn’t work I don’t think they even know what they are doing anymore.

Sorry to hear. I don’t think Porsche headquarters even knows what they did to break things.

Yes, when I called Porsche Canada they didn’t even know anything about the repair.

Following the last software update, I have been able to charge only once at home (after trying a series of different steps which I was not able to replicate). I receive a "charging not possible" error and car fails to recognize the charger. I have tested both my slow chargers (Porsche - second one belongs to a Cayenne Turbo hybrid) and my Level 2 Tersla charger without any success. The car flashes white internally as does the charging indicator when the chargers are connected and goes through the initialization phase but then ends up in the red with the error.

All the chargers work on my Cayenne. Temperatures are extremely cold here, so I will drive it to the dealer today and leave it out of fear it will brick otherwise. I will update accordingly.

I would like to add my observations on this problem prior to my 3rd appointment with the dealer next Thursday.

Since the November 2025 software update (Campaign WSJ0), I am unable to charge at home using either my hardwired unit (Grizzl-E Classic 40 Amp) or Porsche portable unit. Car will charge at dealer with Porsche portable unit, but only after reinstalling software update a second time.

Both chargers are able to charge neighbor's Rivian at my home. Factory resets do not solve the problem.

On dealer's advice that the problem probably lies with the electrical ground in our home, I had a master electrician check our house wiring. He verified that it is up to code and could not identify any problems with either the house wiring or the electrical supply, but as a precaution, he installed a new house ground wire. It did not solve the problem. ($950.00 in case you were wondering) Home electrical service measures 121.5/243.0 volts, 60.0 Hz with no load. Problem persists even with all house circuits turned off except for the charger circuit being used.

Neither charger indicates any fault codes, and both are capable of identifying faults with the electrical current.

Both chargers alternate between showing charging attempted for 5-6 seconds then showing charging paused for 5-6 seconds while the car charging port displays flashing white. Both chargers will repeat this cycle several times until the car rejects the charging attempts and displays solid red at the charging port and the PCM displays "Charging Currently Not Possible".

On rare occasions, if a departure time is selected, the charger will continue its on and off cycling attempts to charge right up to the departure time and may eventually connect just prior to the departure time and then continue charging well past the departure time until it reaches the target charge level. Doesn't always work.

I have attached the complex instructions to the dealers for installing WSJ0. Notice the warning on page 1 that because of numerous dealer screwups, a 23-step checklist on pages 17 and 18 must be completed and signed. My guess after seeing that a second software installation partially solved the problem, at least to the point where AC charging was possible at the dealer, is that the problem might be with the PROCESS of carefully installing the software. Will let you know how next Thursday goes.

This is very helpful. I’ll share this with my dealer, perhaps the installation process needs to be extremely precise and cannot skip steps.

Looking forward to your next update to see how it went.

Just a quick update in Chicago: several other vehicles reported as having similar issues and at dealer. The issue has been escalated from regional oversight in Atlanta back to Germany. I will update accordingly - as I was driving my Cayenne Turbo hybrid back home, a check engine warning came on. Not a good day for Porsche in my family - pretty much cementing my decision to wait on a 992.2 TTS until I see how that electric integration goes.

Geez, I just got the email today to get the WSJ0 update. After reading through the home charging issues you guys are having, I think I will wait this out since my 24 Macan 4 is relatively trouble free. Seems Porsche did not test the update thoroughly enough.

 

[EVOG]

Curious if anyone has been able to resolve their charging issues?

Still no updates from my local dealership.

 

[ScottM]

Still no update here in Chicago. Car has been at the dealer for last 19 days; no fix, no ETA, and no supervisor follow-up from Porsche NA after escalation.

 

[Bolt1323]

Still no update either car is just sitting at the dealership parking lot covered in snow by now. Case has been made but no one has called. Feels like my dealership gave up.

 

[ColdCase]

My recent WSJ0 update seems to not brreak anything and home charging continues to work at the same 9.1 kw rate (Porsche brand wall EVSE).

Note that I do not have schedules, departures, or locations set. It has always been simple direct charging.

I have exactly the same issue, but I have some additional info that might be useful.

My wife's Macan Turbo was updated in November, since then the car refuses to charge at home. The same car charges everywhere else without any issues.

Originally I had ABB Terra AC wallbox 22kw - this has been working perfectly without a single issue until the update.
I have since changed to a different wallbox Teltonika EVC2 22kw - same charger that is fitted in my other home and works perfectly fine with the same Macan. However, it behaves exactly the same as the ABB did and as described by the quoted message.

Plug in -> Relay clicks loudly, then clicks again after 5-6seconds and continues to do the same until the car throws an error "Charging Currently not possible"

All other cars charge without any problems at the same house, with both wallboxes and these are many different brands audi, vw, range rover etc. No issues at all.

Wife's Macan charges everywhere else with no issue (both AC and DC), even with the same type and model chargers, the only place it won't charge is home. I have given my ABB charger to Porsche and they installed it on their premises - also works with no problems.

I borrowed 2 Macans from Porsche to see if it they have any issues charging at my home. One was with the update the other one was without the November update.
- With update - struggled to start charging, but succeeded twice, but after that refused to charge no matter what. Same error and behavior as with mine.
- No update - no issues at all, starts charging as soon as you plug it in.
Since then, the Macan that has not been updated, was updated and I tested it after the update. It stopped charging just like my wife's and the other updated Macan....

I was given a 220v Porsche charger the one you plug into the normal wall socket. I tried it and, first time it started to charge, however, after the second time i tried to use it it started to click just like my wallboxes do and eventually the car throws the same error "Charging currently not possible". This exact same charger i had in my other home as well and i was able to use it multiple times with no issues.

I have just tried the departure workaround - i set the departure time in 30mins and plugged in the wallbox, it was doing the usual relay clicking, but eventually managed to start charging and is continuing to do so even past the departure time (I don't use departure timers at all). This has to be tested further, this is the first time i tried it so I can't say if it is just a fluke and once-off thing or this will work every time.

To me it looks like this is some sort of location related bug, that manifests after the update. Wife's Macan and the other 2 Macans charge AC and DC everywhere without an issue except at that one place which happens to be my home.

So far no solution and no promises from Porsche..

This all looks like a bit of a debacle and sorry to see people having this problem.

I wonder if any of you that have this problem have tried charging at your home with a portable generator (maybe a call out from your AAA? Or a friend with a Rivien or F150 Lightening?). If it charges from a different power source to your domestic power, then it’s something to do with the domestic power supply and the software, if not then it’s something to do with the software and GPS location.
