I took delivery of my Macan 4S last March and I have been very pleased with it. There have been a few minor glitches, but I had similar issues with My Tesla Model S back in 2015.
I had no reason to take the car in for service until 3 weeks ago when I decided to take care of the recalls. They updated the software and replaced a seatbelt component. It was all good until I got home and tried to charge. It stopped charging from my home charger. It gives the error "Charging not possible." I read elsewhere on this forum of a handful of other people running into the same problem.
I took it back to the dealer and they found it charged fine at the shop, first with their charger as well as with my specific Porsche Home charger. I can charge at ChargePoint and at a friends house using their charger.
Today I had an electrician out to measure my 240V outlet. Turns out it is putting out 244V. We had the idea to try to turn off power to the house and switch to our home generator. When powered by our generator, the outlet measured 238V. I plugged in the charger and it worked. I then switched back to house power (while charging) and it kept charging. It appears to only check the voltage range on startup.
According to the ANSI C84.1 standard, the acceptable ranges for a 240V outlet in North America are:
Standard Acceptable Ranges (Range A)
Most utilities and appliances are designed to operate within "Range A" for optimal performance.
It seems to me Porsche HQ needs to issue a new update to change the voltage verification to work with the ANSI standard for North America. We use this same outlet to charge our Tesla and it works just fine.

Most utilities and appliances are designed to operate within "Range A" for optimal performance.
- Service Voltage (at the meter): 228V to 252V (±5% of 240V).
- Utilization Voltage (at the outlet): 216V to 252V.
