2025 Macan EV: electrical errors and undriveable vehicle

[porschemac4ev]

Hi everyone,

I wanted to share an issue I experienced and see if anyone else has encountered something similar.

I have a 2025 Macan EV with about 10,000 miles. Last night the car was charging at home on AC using the included Porsche mobile charger connected to a NEMA 14-50 outlet. During the charging session, I received a notification from the Porsche app that charging was interrupted.

When I went to check the car, it was displaying multiple system and electrical errors. I let the car sit overnight, but the next morning the errors were still present and the car was not drivable:

• Unable to shift into Drive or Reverse, only Park and Neutral
• Multiple electrical systems not functioning properly (Electronic door mechanisms, interior lighting, etc…)
• Charging still unavailable

The vehicle had to be towed to the Porsche service center.

One additional data point that may or may not be related: around the same time charging stopped, the NEMA 14-50 outlet had lost power. My building maintenance later noted that several breakers had tripped in the garage and needed to be reset. After power was restored, the outlet worked again, but the car did not recover and continued to show the same errors.

The car is currently at Porsche for diagnosis. I am curious if other Macan EV owners have experienced:

• Charging interruptions followed by widespread electrical errors
• Loss of Drive or Reverse selection
• Power steering assist failures
• Issues related to AC charging, power interruptions, or the 12V or DC-DC systems

It appears that there may have been a brief minor power outage in the garage of my building which caused charging to be interrupted, with the car being unable to recover. If this ends up being the case it’s extremely concerning - EVs must be able to recover from any kind of charging interruption. The possibility that my car was bricked due to this is a serious issue that makes me really worried about owning this car.

I will update the thread once the dealer provides more information. Any similar experiences or insights would be appreciated.

Thanks in advance.

I too own a 2025 Macan 4 ev that is experiencing the same problem that you described. My vehicle was towed to the dealer last week and it still in the shop. I'm glad you got your vehicle back and hopefully this problem won't happen again. But it is very concerning that it could be a reoccurring issue if Porsche does not have a concrete solution.

Did you ever contact Porsche USA to find out your options?
