MY26 software update (week 36) for MY24-25

[daveo4EV]

They have already came to my house with a 2024 Macan turbo and was able to charge using my charger and their charger but couldn’t get my macan to charge.

yeah - your car is broken and they need to fix it - if they refuse to fix it get legal help to get Porsche to buy it back - I agree with your frustration and would love to hear where you end up…

I'm eye'ing the new BMW iX3 - looks like solid EV product with great specs!!! I'm severely tempted.

make Porsche buy the car back - they are just screwing around with you - I'd be ready with legal flame thrower by now.

They have already came to my house with a 2024 Macan turbo and was able to charge using my charger and their charger but couldn’t get my macan to charge. They are coming again on Monday to see it not charging, feels like they still don’t believe it which is also annoying because it seems like they haven’t even started on trying to resolve the issue and it’s been almost 3 months now.

that's game over for their voltage argument! I'm appalled they are refusing to resolve your issue…they are simply being stupid.

Honestly same they just don’t know what to do and are stalling which I was allowing until now I’ll update when I call on Monday.

That new Cayenne looks cool to drive but I’m scared to go through this again.

well if the updates is rejecting charging because voltage variation then Porsche has a serious bug in their update

software changed and then your car can't charge - that's a fact - tying it to voltage is pure speculation…

porsche needs to diagnose and resolve the issue.

the update has introduced a regression with charging - the car no longer operates - Porsche nees to resolve this under warranty.

Yes definitely a bug and definitely related to the update. But it has been 3 months and they don’t have a fix. Which tells me, they don’t have a clue what’s causing the issue.

I apologize if I replied to the wrong person, this may have been intended for @lukine. Again, I’m sorry if all this has been tried. Just trying to help.

I’m not sure it’s a serious hardware issue with your vehicle. If I have followed this thread correctly, you only have problems charging at your home. Otherwise, the vehicle charges at Porsche and anywhere else. And other vehicles seem to be able to charge at your home with your charger. That also seems to rule out a problem with your house electric system. It appears that there is a software bug that is not allowing to complete the communication between your charger and your car. I would consider doing a factory reset on your vehicle. And if that doesn’t work then ask Porsche to lend you one of their mobile chargers to try at home. Those are simple and cheap solutions if they work. Please forgive me if I didn’t get the facts correctly. Just trying to help. I wish you luck on your ordeal. Also, consider trying a different dealership if not happy with the current one. I have found that some Porsche dealers are more customer oriented than others, even in the same city. I had the same feeling with other brands (BMW, Lexus), so it’s more of a dealership than a brand issue.

my neighbor's Range Rover hybrid charges fine
my other neighbor's Audi Q5 hybrid charges fine
my friends Audi Teton charages fine

You are such a good neighbour. I wish I was your neighbour friend too

You have proved it’s not the voltage as the Turbo charged - the system can’t be overly sensitive or require a precise voltage not least as the voltage in the U.K, Europe, USA are all different !

I’m always an early computer or phone software adopter, even like to beta test. But, I have decided to wait a while before updating the car’s software until all the bugs are sorted out. Fortunately, my Macan has no significant issues!

My car has been at the dealer since December 5th.
Seems the update bricked one or many of the car's computer.
They had to escalate the matter to Porsche Canada to get permission for certain interventions. Nothing solved yet.

Just got news.
The computer handling the battery got bricked doing the software update.
Coming from Germany in February .
And they will be doing also the passenger seat belt, the trunk cover, and the rear latch rattle.
I have a Cayenne S loaner since December 5th.

my voltage right now is 246 volts

my 2024 Macan Charges fine
my 2021 Cayenne eHybrid charges fine
my son's 2022 Tesla Model Y charges fine
my neighbor's Range Rover hybrid charges fine
my other neighbor's Audi Q5 hybrid charges fine
my friends Audi Teton charages fine
etc

if Porsche has updated their software to have strict voltage regulations they are going to brick _MOST_ (all?) of their fleet…and they will have to back out that change and release new software

although I highly doubt that voltage is the root cause here as to why your Macan is not charging - but hey it's software it could be anything

there is simple fact here: car is broken, it used to work, software update is the change - Porsche must fix it under warranty or buy the car back as defective and non-functional.

all of my equipment and vehicles work just fine at 246 volts - and I've seen my meter as low as 218 volts on a hot day in august in California when the grid is under extreme duress…

charging now…

You’re right, every car manufacturer should have a tolerance range. They’re not necessarily saying it’s the house’s over voltage, but they’re definitely entertaining the idea that it’s our house’s problem. They’re even talking to an electrician to see if they can install something in our homes to lower the voltage and see if that’s the reason why it’s not charging. But if you’re saying that it’s just an excuse, then maybe I should not volunteer my home to be experimented on. Wouldn’t want them messing other things in the house up.

So they need to change the hardware then? Computer that handles the battery? Would be interested to learn more so we can have arguing points to bring to Porsche.

Mostly likely will call Porsche NA on Monday explain the situation and see what they say. At this point I just want a buy back and rather go with another brand. I haven’t had one good experience with Porsche customer service, or dealership either as they were either rude or haven’t ever returned my calls when asking for updates on my car.

If they buy back your car you end up losing money. As soon as your car drives off the lot, the depreciation is exponential like 10-20%. I also have had a very bad experience with Porsche. I love the way the car drives, but the software problems and the dealership’s service advisor team have not been very stellar. I can’t think of a good replacement that has a similar price, range and handling as the Macan Porsche. I don’t think the Audi Q6 has the same range. I don’t want to buy Tesla either. So what other options do we have?

if other EV's charge fine - their assertion that it's your voltage was null & void when the other EV they brought over charged fine…

nothing wrong with your house - have them fix your Macan

Yes, a new hardware specifically for the battery that got bricked while doing the sw update.
I'll keep everyone updated.

The weird thing with my car is that it charges at two of my friend’s homes, using my own charger. It just won’t charge at my house. No matter what charger I use, it won’t work at home, but works elsewhere. How can we explain that? If it’s not a voltage issue, then how do we explain the issues I’m having?
