EU/UK: Ongoing navigation issues [Solved with PCM v3892]

[Jasper4S]

Update on February 26, 2026:

It appears that OPC is aware that an update to 3885 is not the solution. Multiple OPC shared information about an upcoming software update. The expected release date is June (11 months after we first noticed the issue).

They replaced my PCM unit, and the issue seems to be resolved for now. But my OPC thinks it is a metter of time before the issue returns.

We discovered that the navigation issues are not only inconvenient but also pose a safety risk. Innodrive crashes along with the navigation, resulting in unexpected behavior and preconditioning of the battery, which sometimes never stops, leading to dangerously high battery temperatures.

I initiated an official complaint against the importer of VOWA in the Netherlands. They acknowledged the issue and will reimburse the cost of Innodrive and Porsche Intelligent Range Manager because these options are no longer usable. (+-€1250 in my case) My advice is to start an official complaint with your country’s appropriate authority (not your OPC).

Update on January 21, 2026:

It’s been over six months since I first noticed this issue. Here’s what we’ve learned from this thread so far:

- It appears to be a problem exclusive to Western Europe and the UK.
- It seems to be caused by the OTA update for the Battery Management System (BMS).
- Turning off Charging Planning is a temporary solution.
- Skoda and Audi forums are describing the same issues starting at the same time as this thread.
- Dealers and Porsche are clueless. Multiple small software patches have been applied, but none of them have been fixed.
- Right now the plan is to replace the PCM units. The units are back ordered and have an expected delivery time of 2 months
- You can request a refund for Porsche Connect. Contact Porsche Smart Mobility. Contact details are listed in the My Porsche section and vary by country. I received a refund for six months.

Hi everyone!

I did a 2-day road trip and ran into a few strange issues. Most were temporarily fixed with the two-finger reset, but I’d really like to understand what’s going on and see if others have similar experiences—or better, solutions.

I’m open to the possibility that I’m doing something wrong or making incorrect assumptions, so feel free to correct me. This isn’t meant as another rant about bad software—I genuinely want to focus on solutions. Here’s what I encountered:

1. Turn-by-turn navigation freezes
   About every 30 minutes, the turn-by-turn instructions would freeze for around 3 minutes. This caused me to miss exits and take wrong turns at roundabouts. This never used to happen—any idea what’s changed?
2. Navigation app crashes
   I use the PCM navigation with Porsche Charging Planner and have PIRM. About every two hours, the entire navigation app crashes—showing only a spinner and then restarting after a few minutes. Each time, I had to re-enter my destination. My trip was about 2000 km, and I noticed the crashes became less frequent the closer I got to my destination. Could the long distance be a factor?
3. Charging stop timeline freezes
   While navigating, the vertical timeline showing charging stops and traffic incidents would sometimes freeze. For example, it showed the next stop as 150 km away while I was actually only 4 km from it. This caused unnecessary stress, especially when the displayed range seemed too low to reach the stop. Re-entering the destination didn’t help—only a two-finger reset resolved it.
4. Charger availability indicators are inconsistent
   Sometimes the system shows live availability of chargers; other times, it disappears completely without explanation. I couldn't figure out a pattern. The two-finger reset doesn’t seem to bring the data back either. Does anyone know what causes this?
5. Charging plan recalculates unnecessarily
   Upon arriving at a planned charger and starting the charging session, the system sometimes immediately recalculates and directs me to leave and head to the next charging stop—even though I’m already charging at the station it previously indicated. Why would it do that?

Would really appreciate it if others could share their experiences or solutions. Thanks in advance!

Cheers Jasper

For 1, I just had it happen to me less than 1h ago.

Maybe some backend issue with Porsches servers handling loading/paying for google map tiles?

the other 4 points are just random porsche shit, I’ve had them all, doesn’t happen all the time, but yea, it happens.

You notice all these problems on longer drives only, and it’s why I suspect so many owners here are happy with the PCM, because they never do long drives to notice all these issues

#4 has never been reliable in the US. Even for Porsche Charging Services (Electrify America, i.e. our version of Ionity). There's at least a 5 minute delay in the data, which renders the feature impractical if you're trying to gauge whether you will be able to charge immediately at arrival. It is reasonably accurate to provide a gauge of general availability/crowding at the charger, e.g. if it only shows 0-1 available during any period that you're monitoring it, then that means there's a line at the charger. If it's showing 2+ available, that means there is not presently a line.

I simply don't trust the data for non- Porsche Charging Service locations.

#5 I'm guessing is trying to optimize total travel time. The phone app's charge planner does this too if it computes your total travel time to be materially lesser if you simply charge up to say 60% at high speeds. This is the case if you're traveling through areas with ample HPCs and high availabilities.

I simply discount this by charging up to 80%-85% regardless. My view is as long as the speeds are no lesser than 75kw around the 80% level, it's a better use of time to finish the charge as max you'll have 5 additional minutes. Overall, I try to minimize my stops to 25 minutes of charging or 85% whichever comes first. I have no patience for any speeds below 75 kw.

It is instant, so I arrive with the planning to stay lets say for 10 minutes and after just one minute it indicates I can go and go to the next charger 25km down the road for another 8 minutes. Like it was doubting its own planning the moment I stopped for charging. Charging speeds are as expected 200-260kw so I don’t think it wants a better charger. It is just recalculating and making new decisions.

I’ve been experiencing #1 for the last 2 days in the UK and it’s extremely irritating. The arrow showing the car keeps tracking correctly but I have to guess at roundabouts and things as to which exit I need.
I’m hoping it’s just a temporary issue at the Porsche server end and not maybe some consequences of processor overheads due to the ARB6 update I got last week.

Just got back from France this evening, and have experience all of the above on my 12 hour journey. Also on the outbound journey a couple of weeks ago.

One other quirk: I use the LeShuttle rail crossing, and the route planner seems to include the miles covered by the train in the projected trip mileage. For the return journey, this resulted in the PCM incorrectly displaying trip mileage as more than the available charge.

I have over the last two weeks had very similar experiences like OP. Plus a few new ones. The only update I have received for a very long time hasbeen Map updates. Last year perhaps som entertainment update but that all. My car was booked into get WRS0 but they could not communicate with the car, no matter what they tried.

1. I have had OP’s issue no 1 today several times on a 570 km drive total. It has not mattered if I drove in town or in the country side. Turn by turn navigation frozen for a few minutes.

For OP’s no 4, the pattern for me has been as follows.
Navigation on a longer trip is working and planned charging stops are displayed. Chargers along the route as well as totally unnecessary charger availability are shown in the main display. Nearly always a lot of chargers way outside of even the existing range, which is of no value and only clutters the screen.
Then suddenly I receive a map update and all information about available, occupied chargrérs disappear Along the route and all over the map area. Plus the charging planner is recalculating the charging stops and sending me to useless charging stations with maybe 2 chargers, without ´ndicating this info, but know it from previous experience.
For number 4 issue I think the map update is the culprit and then does not link to the correct charger database?
I also experience this issue everytime I cross a country border and the car is roaming from one country to the other.

For no 5 I had similar experiences. One added issue was that it did not matter what level of charge I tried to set at my final destination, it had frozen at 44%! Short charges and very short distances to next charging stop.

Some of my issues were solved by a 5 minute battery disconnect, but others reoccurred. Available charging stations etc did return after connecting the battery though.

I see the same as mentioned in another thread. Have previously had many roadtrips with no issues whatsoever with my navigation. But now it's consistenly useless. I drove 1150km today where I constantly had to keep an eye on the map.

I actually got 3 map updates on the trip today but nothing have changed performance wise.

I experienced #2 during a long trip (4800 km). I did not need to restart the PCM since it crashed and rebooted. The problem #1 resolved after the reboot. I also experienced #3, 4, and 5 between 300 km destination stops. These issues were more prevalent when I entered a navigation for long distances that required multiple charging stops, and were less frequent with a one DC charging stop. I believe the cause of problems are associated with the most recent Map update that added, in the US, Tesla (with Magic Dock) and Chargepoint as a part of the Porsche charging network. The new map update does allow the user to select a charging station as an “obligatory stop” but only on the app and not directly on PCM, and with inconsistent outcomes. This was very inconvenient, since I still have one year of free charging at Electrify America. The Map constantly would elect a charging station other than EA, even though the EA charging station was within the area. In one instance, the map took me to a Tesla charging station even though the map indicated that it was EA. I had to use Google Map to find EA. After this update, my Porsche app lost connection with my car. I had to contact Porsche USA and they arranged Porsche in Germany to reset the connection to resolve the issue.

Just got a reply from my dealer, they will start an investigating together with Porsche AG. Fingers

No news yet from the dealer, but I was digging in my current software version for navigation since I can’t remember the last map update. I noticed the navigation pack is empty on the software information page in PCM. Do others with the same issues as described in this thread have the same? If so, my guess is that our navigation pack is corrupt and should be fixed at the dealer?

I have the version number V03959817PV_P1390_EU_2025.08 in that field and as of a few days ago my navigation acted the same way. I did actually get a few updates since this started but none of them seem to have fixed the issue.

My concern is some consequence of the OTA update too. My navigation stopped several times on a journey recently, though I don't use sat nav all the time so it could have more problems than that. I just re-entered the destination.
I assumed at the time I was in a poor GPS location or something.

Just checked and mine shows correctly as shown but still getting turns particularly at roundabouts hanging.
