Thanks all for the suggestions. It turned out to be the Porsche charging cable was in a bad state - with all indicator lights red. The error messages misled me somewhat with the mention of authentication. If they had simply said "the cable is not providing electricity" I probably would have...

Today the Macan continued its fun tour of available failure modes (this car has been in the shop for about 30% of the time that I've owned it). Anyway, today it stopped being able to charge at home with the messages below. I understand that people have had difficulty authenticating at public...

I successfully went online and subscribed to "the Porsche Charging Service Inclusive Period until 3/18/26." However I am having difficulty getting the app to install the corresponding certificate. I see the screen to request a certificate and then an immediate error message saying unable to...

Sigh. Another day another issue with the Macan EV. I've been driving this car for 4 weeks and this will be the third time in 3 weeks that I've had to take it into service. Has anyone seen these error messages? "Transmission error", "Gearshift error". The car started flashing between these two...

Thanks @PrudentOcean. There were cars in all of the adjacent chargers but there was only a single cable coming from the charging unit I was using. This was labeled as a 350kW charger. On the PCM display (the posted screenshots) the max I saw was 120-130kW. I'm not sure what to expect on the...

Thanks, @Petzi. It seems pretty straightforward for the car to measure directly what the charger is delivering or for the car to query the EA network for the capability of the charger.

Of course I'd like to see the car charge as fast as possible, but my issue here was more about the inaccurate prediction of charge time. The car should have almost all the inputs it needs in order to make a good prediction. It knows: indoor and outdoors temps, SOC curve, input voltage.

I was just charging at an Electrify America station. I arrived with charge of 37% and had target charge of 85%. The initial estimate was that target charge would be reached in 15 minutes (which is about what I'd expect). The session ultimately took 28 minutes. The estimate did continuously...

Porsche dealership here fixed the issue. The explanation was that there was a manufacturing issue and the doors were not seated correctly. Hopefully this is a one-off in my case and doesn't show up on other cars.

Thanks @Grahamtaylor , @PrudentOcean , @W1NGE. II've got enough charge to get to the dealer. Will followup here with what they say. Hopefully they give me confidence that this won't happen again or that there is a workaround if it does. This issue does not give me confidence in doing an...

@Grahamtaylor how did you resolve this? My car is in the same state. Nothing I try will open the charge ports.
