So, this may have been obvious to some of you, but this issue definitely affects inno drive also, at least from what I noticed today during a longer drive sessions.

As soon as turn by turn by turn navigation freezez, innodrive seems to dumb down quite a lot, starting to ping pong between lane lines, forgetting to reduce speeds before going into curves, zero awarness of upcoming roundabouts, etc.

And just the same, as soon as turn by turn navigation unfreezez, inno drive goes back to normal, stops the ping pong between the lines, and acts like normal again.

Here is a link to a discussion of the navigation problems on the german PFF Forum:

List of affected persons and their taycan model:

Seems to affect only J1.1 models between 2020 and 2024.

Yes, later models have a newer software running on their communication & navigation ECUs.
There are some people with 2020-2024 cars on the forum that got some ECU software updates also, because their dealer was nice, and they don't have the issue.

Another friend of mine in Zug got his car checked for this issue, they even replaced the ECU, and it didn't fix it. Turns out it's software, but there is no campaign to update, no where to fill in the warranty costs for updating the ECU software, so they are waiting for confirmation from Porsche Central with how to proceed, meanwhile he drives a Macan.

Thanks for the info, mine is getting in next week, will get a j1.2 loaner, hope I can keep it till it is fixed.

I don’t want to celebrate too soon, but I just picked up my car again. Several software updates were installed, IIRC I heard a total 16, including the PCM upgrade to 3885, new headlight software (recall), and even a new version of the navigation app. My Porsche Center did see a lot of issues in the logs related to the navigation software. The navigation feels smoother than I can remember, and I’m also seeing new icons (see attachment). Maybe I was really behind on updates, but the blue icons for AC and DC charging points are new, right? On the 15-minute drive home, I didn’t experience any issues.

I have scheduled my appointment for early October also. Hopefully they finally update my ECUs.

Do you have any work report @Jasper4S, mentioning what was updated and how long it took?

In some countries they release work reports, sadly not Switzerland.

Hopefully the fix lasts and is not something temporary

Will check if my car shows chargers, but I think it does and has for a long time, will edit the post later

Mine is with the dealers at the minute...

They have updated the PCM to 3885 and test-driven it - the issue is still exactly the same and still stalling.

They are trying a hard reset now. If it doesn't fix it, they want me to return it and then they can open a ticket with Porsche -hopefully if others do the same, Porsche will sort it...

It would be a real shame if it turns out not to be fixed. I'll test drive mine later tonight to see if I sport any issues. The positive side is that Porsche AG is now getting questions from different angles. This isn’t a software issue they can just ignore.

The navigation stalling problem doesn't seem to be a hardware issue - so trips to the dealer aren't going to help.

Most posters on this topic appear to be in Europe - has anyone in the US suffered from navigation hanging? My guess is the problem was caused by a recent map data update.

I am also on 3885 pcm version, but I know for a fact no ECUs were updated, and I still have the issue also

It might be the case for you also

Jasper and gtm seem to have gotten some ECU updates also

I just completed a longer trip with plenty of city navigation, no issues at all. And it really seems smoother as before. The PCM was updated, and the service rep mentioned that the navigation system had been throwing a lot of background logs. My navigation pack turned out to be corrupt, which explained the missing software info I reported earlier in this thread. They were instructed not to replace hardware, but to try software updates only.

I don’t have a full list of everything that was updated, but I recall hearing there were 16 updates. That number sounds a bit high, so I might be mistaken.

Since today, I’ve also noticed some UI changes in the navigation. I’m not sure if all my earlier issues were related to the corrupt pack, or if something else was wrong with my vehicle. Do you also see blue icons for charging points? They used to be white for me. My uneducated guess is that the navigation app update did the trick.

 

[csm7djs]

My charging points were always blue.

I’ve noticed the nav seems smoother, but it’s definitely not fixed.

Missed several junctions and then the distance until the next junction froze on 1.0 mile, the car moved on the map so it was tracking via GPS, the blue line was half mile behind where I had driven and finally several minute updates itself.

I agree it’s not hardware, it’s a software issue but without going to the dealers, Porsche aren’t going to be aware or even attempting to fix it. I’m going to call the dealer tomorrow and get them to raise a ticket back to Porsche HQ.

Out of curiosity (since I have not seen this problem), is the missed turn info from the nav unit only on relatively long routes, or does it also occur on short routes in the nav system?

Both, it’s all the time. 1/3 of the turn-by-turn info was wrong/old for me.
