I just confirmed the software update was removed from our Macan EV and is currently charging successfully! Also, confirmed 2 others in Chicago are able to successfully charge with the roll back.

Just dropped off for the update to fix the issue. *Fingers crossed

I just received an update from my service advisor, who heard back from their field engineer. The word is that we should supposedly have a software remedy within the next two weeks. I’ll keep the thread posted as I hear more.

I’ve been tracking the data reported across this community, and a consistent pattern has emerged that suggests a specific conflict between the December 2025 software (WSJ0) and standard North American residential electrical architecture. The Evidence: Certified Infrastructure The most telling...

1. The Standard: Under ANSI C84.1, the national standard for North American residential electrical service, the Range A service tolerance for a 240V nominal system is +/- 5%. This means any voltage between 228V and 252V is officially in spec. Any consumer product sold for the North American...

@toontoon - To answer your question: I took my car in on January 9th. As of today, I am at 39 calendar days out of service. Regarding the high priority claim: Be extremely careful with that. I received a generic response from Porsche NA yesterday at 9:33 AM that offered zero specifics. While...

@toontoon – Don’t let the 50%/100% toggle or the light colors distract you. I’ve been through the exact same loop here in Chicago (now 37 days OOS). My dealer actually sent a technician to my house with Porsche diagnostic gear to settle this. We confirmed the car sees a compliant 245v at the...

@Dandar245 – Your voltage theory is spot on, and I have the diagnostic data to back it up. I’m in Chicago and have been dealing with this for 37 days. To isolate the issue, I had a master electrician verify a steady 246v at my home. More importantly, my dealer actually sent a technician to my...

Unfortunately, these troubleshooting steps don’t resolve the issue for those affected after the December software update. For several of us, that update appears to break home AC charging entirely. I went through all of these steps back in December after installing a Tesla Wall Connector...

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.
