How does Porsche learn about its software fragility?

[anonymouse]

The Taycan has more significant transient bugs than anything I’ve owned in recent years.

By “significant” I mean temporary faults that render part of the functionality unavailable, or even the whole vehicle, then self-repair when the car has been asleep for an unknown period (usually hours or overnight).

Recent examples from my cehicle
- yellow electrical fault warning
- instrument panel failure, inspection required
- alarm ringing constantly
- lane keeping unavailable, inspection required
- charging not possible

In each case there has been significant disruption and concern - especially when they happen on a road trip or on the way to a crucial appointment.

so…
I wonder how Porsche “feels the pain” as we do. Do they see logs? I doubt that OPCs provide meaningful data — they book the car in as a service visit then all these transient faults are “no problem found”.

How do we ensure that Porsche is finding out about these many issues, and — if only! — pushing bug fixes to the fleet??

Maybe fill out some of those independent surveys that measure owner satisfaction. I don't know which ones they have in other countries, but there is like JD Power, etc here in the US.

I don't look at the results closely, but I believe Porsche usually scores pretty highly on those surveys. I would imagine if that started to change, then someone at HQ would notice and react.

Great question!! Just yesterday I emailed them and asked, at the least how can I submit bugs for all the various things that come up. Waiting on reply.

Good idea. You could also ask them if they have any intention of fixing ANY of these bugs. It is ironic that their website says “over-the-air updates will be installed automatically from now on without having to visit a workshop” but I have never had a single bugfix update, just endless alerts about map updates.

I haven't had any problems like that. I imagine you've been to your local service center and had the car reviewed. Though OTA updates never fully materialized for Porsche, they do have updates to apply at the dealer. Good luck.

yes. Towed there once, been there twice. Had the whole car reset once. All updates are apparently already applied.

Very good question!

I have emailed Porsche, both my local service manager as well as Porsche France representative several times about issues like that. But really nevere hear of any action back.
At one was asked by the local guys to bring the car in as soon as I saw a fault displayed several times. I took shots of my cars screen and sent that to the service guy, drove to the centre and made the mistake of switching the car off. RESULT: No information left in the log in the car about the event.

Got a very similar fault message a week later, drove again to the centre but did not switch the car off. This time the service guy could download a lot of fault messages! He switched the car off and tried again. All faults cleared!

It is badly written Software.

Yes, I had the same after a fault requiring towing. Porsche’s logging seems quite poor. Perhaps they missed that lecture on the software engineering course since about 1980.
