My 2024 Macan EV Never Seems to DC Fast Charge at its Potential

[USMA81]

As humans, we make decisions on how the future will be based on limited information; the actual future may be better or worse. Additionally, we form opinions based on experiences and then our memory recall can accentuate impressions; all of this eventually leads to general conclusions that may or may not be based in facts, and yet it is our reality. A Nobel laureate in psychology said, “What we see is all there is,” a play on WYSIWYG. We all do it. None of us is the perfect, rational human being.

I bought a 2023 Audi Etron, which I intended to keep for six years. Over two years, I’d had some minor problems with the software, the 220 mile range seemed more limiting than I anticipated, the vehicle didn’t have a tow hitch for my bike rack, and I began to dislike the fact that it was engineered upon an ICE chassis (for no reason than I considered it imperfect). All of this I knew when purchasing, but my views changed over time. And yet overall it was a terrific vehicle. I traded it four years early, something that I presume 99% of owners would not have done in the same situation. I took a good hit on depreciation. When I look back at the decision to trade and I look at the vehicle in total, I see that all of these issues were trivial, but they were important to me (and correctable in a different vehicle) - but also pretty irrational.

So I will defend your wife’s views of the Macan, but you now know 99% of the owners here don’t share those views, either because they aren’t experiencing the issues she is or because those issues aren’t as important to them.

No need to belabor this, but:
- I plug in to DC charging within 5 seconds of opening the power port (I get the cable first); the value of the power port is that it is lighted (Ok, small value).
- I have slow and fast charging speeds at the same charger on different days; I accept differing DC speeds and know it is not the car.
- I think the software is ”pretty good;” I don’t need to see diagnostics on charging. I get very occasional error messages, but they resolve upon restarting the car; no biggie to me.
- I don’t view Macan charging as somehow unsafe or flawed. I don’t charge at Walmart after closing hours.

Still, yes, I know she feels differently and I respect her views.

This thread is never-ending. Keep the Macan and accept what you don’t like, or sell it. I’d suggest you just move on. Trade the vehicle. Not every decision works out as we plan.

I will take you to task on one issue: you’ve made 50+ posts in this thread, and now state, “I don't have to discuss the car's systems problems here.” Really? At the risk of furthering this thread, and without rehashing what has already been posted, I’d like to know what issues are being replicated, what things are you experiencing that perhaps others are not. Maybe these issues being replicated are the same as you’ve previously posted.

Hey, fun note. The worst of our issues require the reset of the car to either charge or drive. Asking her to ignore an error message that says something like, "high voltage system may have failed ... call Porsche service" and then reset the car is always going to make her feel uncomfortable. Primarily because if she's road charging, she's in an environment that she doesn't want to be trapped in. A few of the scenarios were mentioned here, and my wife has taken the lead to work through the set with another group more interested in engaging on them. She wants to make an EV work for her and is disappointed that she can't find a way to feel comfortable with it.

The Macan EV issues have led to her deciding not to buy a Cayenne EV as an additional vehicle to replace another ICE SUV that we own. When we bought the Macan ev, we assumed depreciation would kill its market value at a rapid rate, and we (someone in our family or friend group) would get out of it what we (collectively) could. If she really wants to sell the Macan EV, she's welcome to do it. It's her decision.

high voltage system may have failed ... call Porsche service

is that error message actually occur???????? - yes you should pay attention to that - but it's really relaly hard to sort your actual problem, potential problem, what problems you actually have, what problems you might have, and how often this problems (if they are problems occur)

you keep presenting "straw man problem(s)" but never the actual specific problem(s) and why a different EV might be better/worse/same…

as thinking humans - one should be able to "sort" the "really urgent" problem (high voltage may have failed) from the ho hum errors "assistance systems unavailable" - those two errors are not the same urgengy.

• you're all over the map
• you keep changing "the problem"
• your proposed solutions make no sense and will not solve the problems
• and the big "threat" is you're not going to spend $150k+ on an un-necessary luxury SUV from Porsche - hint: this is privilege, not a threat
• and keep switching the problems between Porsche and external factors Prosche can't control
• and so far of _ALL_ the problems presented - I"m not quite sure any other EV wouldn't have similar issues
• and then you demure and suggest "you're just the messager" and really your wife is having all these problems and she's meeting with her friends to talk about how horrible this all is
  • NOTE: we still don't know actually what was horrible?
  • was it the homeless person that she was uncomfortable with? yeah that will really be fixed by adding diagnostics to the Macan EV
    • and yes homelessness is a serious problem and one that continues to stymie the most powerful nation in the world - and yet it's part of this thread…strange.

I don't think anyone here can help you - and the "feedback" is there is any is so unfocused I don't know what you're optimizing for anymore…or even what would be better and what would be feasible - certainly buying a TEsla, BMW, or Rivian won't change the homeless problem that was noted…

I remained convinced there are in fact problems…

I, and I think most now on this thread/forum, fully support your decision to not buy a Cayenne EV - regardless of your reasons and I still suggest you get rid of the Macan EV as fast as possible - if not for you - then us.

Thanks, Dave. That error message was easily replicated by a mom, reading the thread and blocking the automatic charge port doors at a DC fast charger.

so you're upset that the car can be "tricked"? let me count the ways _ALL_ vehicle's can be tricked and cause false sensor errors.

does the problem persist?
how was the DC charging door get blocked?
did hte problem cause the charging session to be slow?
was it easy to see what had happened and avoid the issue?
was it not clear blocking the power charge port door caused the car to throw an error?
was there an actual functional problem - or did hte error just cause "distress" when in fact there was no problem?
I didn't do my self but I heard from Jenny, that her friend George, saw a guy at an Arco station put a gas fuel filler into the DC fast charging port and got extra range…

so you're big contribution here is to play "telephone" with how your wife and her friends are trashing the Macan off thread?

and again - the big "threat" here is you're not going to buy a Cayenne EV? so again: Privledge.

Dave, I came here to exchange information with other people to learn.

I observed her charging issues because I was with her for support while she figured it out. I did not intervene because she asked me not to.

*You* are judging *her* for how she feels when the car acts differently than she expects.

I’m starting to wonder… could Steve actually be a troll bot account developed by the infamous west coast tech mom network? ?

If you’re getting error messages, however caused, why is your wife trying to diagnose these, and to replicate them with her friends? Get the Macan to the dealer and have a discussion with them to eventually get the issues she has fixed or at least explained. They are the experts on the car, something your wife (and all of us) will never be. That would be my first and most immediate action.

Is it possible that the German wording of “high voltage system may have failed” should have been programmed to say, “port blocked?” I was the original poster of the problem with blocked ports. It is indeed a problem, but another poster more recently seemed to indicate that Porsche had changed the software to partially or fully address the issue. More to the point, while it is a flaw in the design, it is one that is avoidable if one is careful and using the port and charging system as intended. Beyond any simplistic advice or, “Gee, yea, mine does that too” commentary here, your path to answers and sanity lies through the dealer.

I’m out.

Thanks.

The dealer was consulted and their initial reaction was "sorry. We apologize for the rough edges." They asked me to wait on a software update at the time, but we haven't nailed down a time because my schedule put me elsewhere. I will run a software update on the car when I'm back with the car to manage the process with them.
