Totally agreed. My Taycan was out of commission for nearly a week last month with this issue, and it’s the second time that it has happened this year. Both incidents required a dealer visit to resolve.in my case - sim status shows good bars and celluar network (Verizon) - in the case of Taycan you can't connect to home-wifi - so if the cellular connection is "wedged/hung" apparently it requires a dealer visit to "reset/restore" the modem's sanity…
it boggles my mind that…
I'll provide details when I have them - as I said the next time I have to go to the dealer I'll be dropping my Taycan for this repair - I hope to visit the dealer sooner rather than later, but right now I'm in world wide shipping logistics hell so I have no idea when my opportunity to visit the dealer will present itself.
- this requires a dealer visit
- it's a problem that doesn't fix itself will a full power down (disconnect the 12v battery)
- that it can come to this
- Porsche knows about it and has no apparent plans to 'fix' it
- that if my car was out of warranty they'd charge me to fix it
In my case for 12v reset ……… The second time when it worked I left it disconnected for thirty minutes, the first time when it did not work I had left it for only 5 minutes.May I ask how long you had the 12v disconnected for?
big fucking mood right there.owner frustration and further confirmation that Porsche's mastery of all things mechanical is starting to wear thin with an ongoing set of "digital snafu's" that are unbecoming on a $150k+++ vehicle
I am curious about symptoms of a CONBOX battery needing replacement. I would hope there would be a clear warning on the PCM, but having experienced Porsche software, I would not bet any money on it - it could just manifest itself as random OTA or connectivity issues.Possibly, the variation in the amount of 12V disconnect time necessary to effect a reset may be related to the state of the cell modem backup battery which gets clobbered with age.
car is back online after a dealer visit - I'm picking it up today - I can tell it's fixed because I can access the car remotely now even though I have yet to pick it up!!in another chapter of Porsche's mastery of all things digital - apparently the vehicle's cellular modem can get wedged to such a degree that while it has a perfect cellular signal it will refuse to engage in any actual data transfers. Symptom's include but are not limited to:
according to myPorsche app - my car has not been seen online since Oct. 16th…I finally tried to diagnose and recover it this weekend and there was no joy…
- PCM weather app offline
- PCM news app offline
- PCM no traffic updates on navigation
- PCM in ability to login into different porscheID accounts
- no remote access via the myPorsche app
- owner frustration and further confirmation that Porsche's mastery of all things mechanical is starting to wear thin with an ongoing set of "digital snafu's" that are unbecoming on a $150k+++ vehicle
- two lines with a slash through them indicate no data service is functional - this icon is not helpful or remotely diagnostic - the "icon" shows up in the upper right portion of the upper center screen
800-PORSCHE confirmed the problem this past weekend and provide a detailed writeup for me to show my Porsche dealer such that they can resolve the issue with a dealer service visit. The phone representative confirmed this is a known issue, but no fix other than dealer service visit is available at this time. The customer support level of this phone call was excellent - polite, knowledgable, and a targeted resolution - but this problem should not exist and if it does it should not require a dealer visit to resolve a "wedged" modem - but I have zero complaints about the actual phone call…
NOTE: if/when this problem happens out of warranty it would be a for-pay service at your dealership to "reboot/reset" this wonky Modem in the vehicle - for that I lack words and consider this utter crap - my Taycan is still in warranty - but honestly a dealer visit to reset/reboot a fault component that isn't a hardware fault? This would not make me happy.
I plan to drop the Taycan off for this "fix" when I have reason to visit the dealer for other reasons later this week…
Taycan's a great car - but other aspects of it after 3+ years of ownership are wearing thin…
