⚡️ Home Charging Issues after Software Update? (Tracking Thread)

[Bolt1323]

Just got my car back, charging now works. Also found a bill from a fast food place guessing they took the car out for a ride. Don’t know if they allow to do that.

Unsure about it. I am attaching the email I got. Feel free to call Jacob (he is Porsche NA's Connect and Charging Expert). I will direct message you his direct line phone number.

The guy at Porsche Canada (who isn't even located in Canada) still hasn't e-mailed me about any fixes. My dealership still having trouble updating my car apparently. So I have not been as lucky as some of the users here who received the update.

To those who received your updates, has there been any discussion about compensation? 4 months of no at home charging should at least warrant some sort of compensation.

Porsche don’t even pick up my phone calls no more. I fully lost confidence in Porsche after this whole situation.

You should discuss it with Porsche NA. Maybe they can extend your free DC charging for the same amount of time!

I was so relieved that the update worked I did not think of any compensation. Turned off the auto update function via the app.

They tell us that DC charging too much is not good for battery life. And this AC charging issue was caused by Porsche’s update, which forced all of those affected to strictly charge using DC. I feel like after being forced to DC charge for months at the very least would warrant an extended warranty on the battery. Not to mention the inconvenience and time we had to spend in order to charge our cars. It was literally worse than owning a gas car because charging in freezing temperatures with a cold battery (unable to precondition battery in just a 20min drive) was slow vs a 5 mins gas stop.

Anyway, my dealership is having issues updating my car. They’ve been trying for the last few days and it keeps failing. Now they’re thinking maybe they need to change the charge box. I wonder if this is the same issue as yours @FirstEV. They started another ticket to confirm with Germany if this the right course of action.

I really hope it’s the same issue, because if that’s the case it’ll be resolved very quickly once they decide to change the hardware, and my issue will probably already be noted in their “records,” allowing for a faster decision on their end. The main issue might be that it takes some time for the dealer to receive the spare part, but it’ll be worth it.

I would stress that if you can at least get an EV loaner or a plug-in hybrid (Cayenne), it would be in your interest. You’ll save a lot of miles and be able to charge at home. Hope they figure it out!

You are right, DC charging is not as good as AC for the health of the battery. However, the impact is minimal on the overall life of the high voltage battery. My point is that you should definitely request some sort of compensation from Porsche NA given the amount of time that it has taken to fix a problem of their creation. Although getting an extension of the HV battery warranty may seem good, it is unlikely that you would actually benefit from it considering that those batteries are designed to last a lot longer than the offered warranty. I would push for a monetary compensation or for an extension of the free DC charging period which would be useful during longer trips, specially if you decide to visit a warmer location

I suppose. But I rarely use DC charging and I likely won’t benefit from an extension of 4 months either as I don’t take road trips very often I guess we will see if they even offer anything. Judging from the zero communication from the case manager at Porsche NA, I think they’re hoping once the issue is fixed, that I will be satisfied and leave it alone.

‘A 2026 Geotab study found that frequent high-power (>100 kW) charging increases annual degradation to about 3.0%, compared to 1.5% for mostly AC charging”.

That means, on average, if you use DC fast charger, on a regular basis, compared to home charging, you are degrading your traction battery 100% faster. So, after 5 years, instead of getting 300 miles of range, you’re now getting 255 miles of range. Not the end of the world, but there is a measurable difference in the long run.

I think the equation of whether one should worry about this, or not, depends on whether you plan to turn your car over (to get new one) every few years, or do you plan to hold on to the car, for say 5-10 years? Since the depreciation on cars, and especially EV’s, is the steepest in the first 2-3 years…if you are inclined to turn the car over in that time period….you don’t have to sweat about the battery degradation….but you are paying for that privilege.

My car is also due for "update" following the engineer visit. As far as I am aware this is just an update or more likely downgrade of a specific module which is causing the charging issues.

Update: the car was updated or more likely the charging module updated/rolled back on Friday - so after 5months my car finally charged at home for the first time without involving some sort of trickery with air compressor or central vacuum system

Happy it was finally resolved!

That's great to hear! Do you have some information (update number, release number / notes) about the European update you got?

I typically keep my cars for over 10 years. Which is why it matters more to me. Switching to a new car every 3-4 years is bad for the environment too. That’s why my typical car purchase is Japanese as they’re more reliable. As my first EV, I considered Porsche because they’re the top European car maker that’s more reliable and comparable to Japanese, and it drives a lot better than a Japanese car. But because Toyota is lagging behind on EV adoption, I switched from Lexus to Porsche.

Now I’m regretting it a bit

I’m happy for you. Thank you for allowing Porsche do the testing and investigating at your home as well.

My first EV was a 2022 Polestar 2 (P2), with performance pack. Still have it, still love it. Chinese made, with Swedish design. Other than the usual EV-related software glitches, the Polestar has been extremely reliable for me. Pretty much all the software updates from Polestar are OTA. Currently looking at the P4, as a replacement for my last ICE car.

I also own a 2025 Macan S EV and a 2013 Lexus RX350 (ICE). The Macan EV has had a number of software glitches, but as an EV owner, this did not alarm me. Overall, very enjoyable car to own, although reliability is not top of the charts, IMO. The Lexus has been bullet proof. Boring, but bulletproof.
