2025 Macan EV: electrical errors and undriveable vehicle

[porschemacanev4S]

Same here: 2025 Macan 4S delivered in February 2025. In shop for 1.5 months, no progress just trial and error tests with limited EV personnel. Supposedly CA lemon laws kick in if unfixable after 30 days. Have you looked into that or maybe a class action lawsuit would get a better response from Porsche?

Wow, that’s really interesting (and unfortunate). Sounds like our cars were likely produced around the same time. It definitely helps to know I’m not the only one dealing with this, even though it obviously sucks for both of us.

Was your failure similar to mine? In my case it was a high-voltage system fault that left the car completely undriveable. I’m approaching the 30-day mark now, and the part that was ordered to address the issue is still stuck in customs with no clear ETA.

It’s surprising that a brand like Porsche doesn’t seem to have domestic stock of critical high-voltage components to support timely repairs, especially on a brand-new EV platform.

One thing I did do was open a case with PCNA directly. That at least helped elevate the situation and put some additional pressure on the dealer, and my case has since been escalated for further review. I’m still waiting to see what that leads to, but it’s been helpful to have corporate involved rather than relying solely on the service center.

Overall, this experience has left a pretty poor impression. I’ve never been without a vehicle for this long before. The loaner helps, but it’s obviously not the same as having your own car back. At this point it’s definitely made me question long-term confidence in the platform and the ownership experience, and I’m trying to understand what options might make sense going forward.

Yes same issue of being stuck in Park and Neutral, among other issues. No parts have been ordered to my knowledge. In my situation it seems to have been a compounding of faults starting with the November Fall-back time change which appears to have caused the underlying time zone to be out of synch between the car and app. The car updated correctly (time zone and time) but the app didn't. Manual updating didn't help. I didn't notice this until I tried to increase the battery charge to 100% for an upcoming trip and couldn't. Somewhere along the line I also got an error message (Fast Charging not possible. AC charging possible, visit workshop) and the manual Fast Charge door no longer opened. I was using the passenger side charge port. Dealership tried walking me through various screens to no avail and told me to call PCNA. PCNA checked their dbase and drew a blank so they pushed me back to dealership. How were you able to get PCNA involved? When I tried to drive to the dealer it would not go into Drive or Reverse, so it was towed and they said they weren't able to even look at it for a couple of weeks (limited EV mechanics). Not sure if these issues are somehow connected but they seem to be and the only other potential accomplice might have been my washing the car (by hand) preceding the attempt to increase the trip charging to 100%.

Thanks for sharing. That does sound very similar, especially the stuck in Park/Neutral and charging-related errors.

In my case the dealer ultimately found fault codes pointing to the central high-voltage box, which is what made the car undriveable. A replacement part was ordered from Germany, but it’s been delayed in customs with no clear ETA.

I was able to get PCNA involved by opening a case directly myself and explaining that the vehicle was completely undriveable and had been towed. That helped escalate things beyond just the dealer, even though progress has still been slow.

Definitely keep me posted on what they find on your end…the overlap here is concerning.

Hola a todos,

Quería compartir un problema que experimenté y ver si alguien más ha encontrado algo similar.

Tengo un Macan EV 2025 con unos 16.000 kilómetros. Anoche, el coche se estaba cargando en casa con el aire acondicionado usando el cargador móvil Porsche incluido, conectado a una toma de corriente NEMA 14-50. Durante la carga, recibí una notificación de la aplicación Porsche indicando que la carga se había interrumpido.

Cuando fui a revisar el coche, presentaba varios errores eléctricos y del sistema. Lo dejé parado toda la noche, pero a la mañana siguiente los errores seguían presentes y no se podía conducir.

• No se puede cambiar a marcha adelante o marcha atrás, solo estacionamiento y punto muerto
• Múltiples sistemas eléctricos no funcionan correctamente (mecanismos electrónicos de puertas, iluminación interior, etc.)
• La carga aún no está disponible

El vehículo tuvo que ser remolcado hasta el centro de servicio Porsche.

Un dato adicional que puede o no estar relacionado: casi al mismo tiempo que se detuvo la carga, el tomacorriente NEMA 14-50 se quedó sin suministro eléctrico. El personal de mantenimiento del edificio notó posteriormente que varios interruptores automáticos se habían disparado en el garaje y era necesario reiniciarlos. Tras restablecerse el suministro eléctrico, el tomacorriente volvió a funcionar, pero el coche no se recuperó y siguió mostrando los mismos errores.

El coche está actualmente en Porsche para diagnóstico. Me gustaría saber si otros propietarios de Macan EV han experimentado lo siguiente:

• Interrupciones de carga seguidas de errores eléctricos generalizados
• Pérdida de unidad o selección inversa
• Fallas en la asistencia de la dirección asistida
• Problemas relacionados con la carga de CA, interrupciones de energía o los sistemas de 12 V o CC-CC

Parece que hubo un breve corte de luz en el garaje de mi edificio, lo que provocó la interrupción de la carga y la imposibilidad de recuperar el coche. Si esto sucede, es sumamente preocupante: los vehículos eléctricos deben poder recuperarse de cualquier interrupción de carga. La posibilidad de que mi coche quedara inutilizado debido a esto es un problema grave que me preocupa mucho.

Actualizaré el hilo cuando el concesionario proporcione más información. Agradecería cualquier experiencia o comentario similar.

Gracias de antemano.

Hola, el pasado 16 de diciembre tuve el mismo problema con un macan 4s 2025 con 8.100 km, a día de hoy todavía está en el taller de porsche barcelona y pendiente de reparación. Misma situación y mismo fallo. No me dan explicaciones ni coche de sustitución. Un desastre. Saludos.

Thanks for sharing this. I used a translator to understand your message. I’m really sorry you’re dealing with the same situation.

What you’re describing sounds extremely similar to my experience as well: high-voltage system failure, the car becoming undriveable, and a very long wait with little explanation. It’s especially frustrating that you haven’t been provided a replacement vehicle.

It’s concerning to see such similar issues happening in different countries with the same model. I hope Porsche is able to provide a clear solution for you soon.

If you receive any updates about the cause or repair, please feel free to share. Wishing you the best. I know how stressful this situation is.

I ran into this same issue in December. Our home wall charger has worked flawlessly for 5 years with 3 different Teslas and for a year and a half with our Rivian. Once, the breaker tripped while charging the Rivian but the car was unaffected and started charging normally again after I reset the breaker.

2 weeks after picking up my CPO 2025 Macan EV (~5,000 miles on it when I picked it up, first driven in 03/2025, I picked up 12/2025), I experienced the exact same issues you saw. The breaker on our home charger had tripped, charging interrupted, car would not go into gear. Towed to our service center. HV Box replaced (12 days in shop).

Last week, exact same thing happened. Breaker blew on our home charger, charging interrupted, car undriveable, towed to Porsche. This time they are saying they need to replace the "gateway control unit," which is on order from Germany. The blowing a breaker to me indicates something much more serious, like a short in the onboard charger - hard to believe a control unit is all that's gone wrong. I get the impression they have no idea what's actually wrong. Thankful we have lemon law here in CA.

Thanks for sharing this. I see you’re also in San Francisco. Is your service being done at Porsche SF as well?

My car has been there for over 30 days now, and they’re only just starting to work on it this week. You were at least able to get yours back after 12 days the first time.

This is becoming extremely concerning, especially the fact that the issue repeated after the HV box replacement. There now seem to be several reports in this thread of the same or very similar issue occurring in different regions.

The breaker trip triggering the failure really stands out to me too. We’ve had the same home charging setup for years with other EVs without a single issue, which makes this very difficult to understand.

Please keep us posted on what Porsche finds with the gateway replacement. Really hoping they’re able to identify the true root cause.

Wow, super concerning. Yes, our service is also being done at Porsche San Francisco. We leased our car from them, it had previously been one of their loaners. First issue happened on 12/18, ready by 12/30. Second failure/tow in was this past Thursday 1/22. I'm worried that all these individual part replacements (HV box, gateway control unit) won't do anything about whatever the root cause is - something more architectural must be causing these parts to fail.

I'm interested in also opening a PCNA inquiry at this point - OK if I DM you to ask how you did that?

I completely agree with you. At this point it feels less like isolated part failures and more like something broader that isn’t being fully identified yet.

For PCNA, I simply contacted Porsche Cars North America customer support through their website and opened a case. I explained the failure, extended downtime, and concerns around reliability and communication. That created a formal case and assigned me a representative who has been coordinating with the dealer since then.

I do think it’s important for PCNA to be aware when multiple similar cases are occurring, so they can better understand the scope of what owners are experiencing.

Happy to share more details via DM. Feel free to reach out.
