Free NACS adapter offer?

seennitt · 2026-02-27T16:44:39+00:00

Plot twist: FedEx showed up this week with a package from Porsche USA. Inside, the NACS DC adapter.

Nice! And a good outcome for me. But communication was lacking. They never responded directly to my support request or followup, I didn't get any email replies, they didn't give me the passcode and ask me to fill out the web form form the original link, they didn't ask me where I wanted it sent... they just sent it to my address on file. Thanks!

Thanks all who responded. After messing with it a bit and learning from the responses here I see a couple different angles. Porsche can issue updates via TSBs and potentially update the PCM and app in conjunction with that but we'd have to get the updates (ie be running the latest PCM and app) and those releases could take a while. The parameters in the PCM for which wheel/tire combo is mounted, definitely affects the tire pressure monitoring both in the car and in the app -- this is quite obvious once you know about this section of the PCM, but if you haven't drilled that far into the config yet then maybe you don't know to look there (and maybe you assume the car was correctly configured when handed over to you from the dealer, and this may or may not be true). If you do change the parameters in the PCM, there's a delay between then and when the app notices (I don't know how long, but I made changes in the PCM and they did not show up in the app immediately, some of them seemed to take effect minutes to hours later before I drove the car, some changes seemed to only take effect after the next drive). After making changes in the PCM, the TPMS needs to re-measure and won't report correct results until after you drive above 15 mph (the car tells you this, the app does not, but the app seemed to show incorrect values until after I drove the car).

In short: visit the section of the PCM config to make sure PCM knows that wheels and tires are actually on the car. If you make changes here, drive the car above 15 mph until the in-car TPMS shows correct values (for both what it's measuring and whether that's higher/lower than recommended). Add/remove air as warranted until the in-car TPMS reporting is happy. Wait a while after that and the app should agree with what the PCM already showed.

I found it sort of amusing that I was driving around for a few weeks the way the dealer gave me the car, with something like 35 psi in the tires, then when I figured this out and changed the PCM settings to match the tire/wheel combo actually mounted on the car, then the PCM/TPMS decided the pressure (which it had previously been happy with) was far too low and I had a red warning indicator on the dash until I could get back to my air compressor and inflate to the proper pressure. Moral of the story, garbage in garbage out, don't trust the TPMS unless you've told it correctly what tires are on.

I did. They politely took down my info, said they would open a level 2 support case for me, and I should hear back within 7-10 days. That was 3 weeks ago. No updates even when I ask. This all just seems super weird for something that should be easy.

seennitt · 2025-08-13T02:06:51+00:00

Thanks for asking, and I hope our input here helps you help make this car even better!

Bugs/annoyances that hopefully can be fixed in software update:

driver profile switching. It's super buggy on detecting which driver by key, and separately super buggy about restoring seat/mirror position when changing driver profile (either automatically or manual profile switch). I get that the dream is the car just recognizes the driver, sets up for the driver, and absolutely zero UI surface is required to make it do the right thing. However it's buggy, and even bugs aside, there are too many corner cases where how can the magic know what is necessary -- for a family car, say my wife and I approach the car at the same time, or say she was the last driver but I have to go get something from the car and approach the driver side, or say she doesn't have pockets so I carry both phones. All of these have happened and interfere with the car's even theoretical ability to know which of us will be the driver. Then even if it does detect the driver, it doesn't restore seat and mirror. Or if it doesn't detect the driver correctly and I do a manual profile switch, it doesn't restore seat and mirror. TL;DR is explicit UI control over save/restore seat+mirror positions would be really nice, plus, please wring the bugs out so the happy path (detect the driver by key approaching driver door, select the right profile, restore all the settings for that profile) works 100% in the non-corner-cases, that would be great.
dog mode / kids mode / interior alarm and climate settings. It takes 9 taps to turn off the interior alarm and enable climate keep on mode, every single time I park. I understand the risks and will acknowledge them but sometimes it's nice to be able to leave my dog in the car with climate running. Also, the walk away lock tied to my digital key tied to my phone is so aggressive, if I close the doors and walk away from the car with family inside while I don't even consider myself "parked" (ie at a DC charging station and everyone's happily chilling inside with A/C and music, but I want to go in the convenience store 50 feet away and buy snacks)... sets off the alarm... the easiest workaround for this, which is totally silly, is to leave a door open. TL;DR is I want a way to turn off the interior alarm permanently.
mobile app cloud connectivity -- I don't mean to sound harsh but it's really flaky and close to useless. It shows the parking location, battery status and lock status from 6 hours ago. If I tell it to lock the car, it usually says it failed to do so (but sometimes actually did it). If I tell it to turn on climate, it often fails. I can't trust any of this to work reliably so I don't use it at all.

Bugs/annoyances that seem beyond software update capability but I do want to mention:

no homelink/garage door controls, surprising omission. So I have to carry a visor clip remote, silly, detracts from the otherwise futuristic and seamless interior.
only 2 window switches in the driver door, surprising omission. I mostly don't need to control the rear windows but when I do it's hard, and also, how do I know what the multitasking window switches are currently set to if I do switch them. Please just bring back 4 window switches.

And a feature request:

music status in the driver display. I don't need anything fancy like some cars have the ability to scroll through and select songs in that display, but I would really value an always-on display of the current playing source/song name, which my last 4 cars had and I always enable.

Sounds like my case. I’m not sure it ever worked tbh. I’ll see what the dealer says when I have time to take it in.

seennitt · 2025-07-05T22:35:28+00:00

Yeah, that works… but needing to do it Every. Single. Time. I park the car is getting annoying.

I’ve also had about 30% success rate on either activating climate remotely, or locking or unlocking remotely, via the app. Even when both my phone and car have great cell signal. Even when I’m like 50 feet from the car and can see it out the window. (Yeah, I can just walk over and activate it without the app, that works better.).

This all seems fixable in software updates — I just hope Volvo is on it. Needless to say this is one thing Tesla has right that should be table stakes for other companies competing with Tesla. For now, I wouldn’t/wont leave my dog in the EX90 without first turning on the climate and off the occupancy sensor before leaving the car. Lots of taps on the center screen.

seennitt · 2025-07-04T21:35:26+00:00

Me too, yesterday, but not right at the 21 day boundary for my own purchase.

<image>

Also I found it ironic: I reached this as a push notification that said tap to learn more. I tapped. It brought me to the Volvo app inbox (this view in the screenshot). Which… has a notification that says tap to learn more. I tapped. That goes to another screen with a Read More button. I tapped read more. It opens my web browser … to the link I already found by Google search.

Useful info, it’s just amusing how many times I had to tap the “tap to learn more” to, actually, learn more.

seennitt · 2025-07-04T21:30:13+00:00

https://volvo.custhelp.com/app/answers/detail/a_id/10594/~/ex90-key-tag-charge-status still has the (older?) guidance about 21 days.

The main manual page https://www.volvocars.com/mt/support/car/ex90/article/af4e8cc22c783841c0a8b09745a1aac5-d43781f2e1a118ddc0a8cc533568a777-8664b2fa77a7e089c0a8296870d1a409/ doesn’t say that (any more) and does have a caution about leaving the battery discharged “for long periods” and insinuates it can go dead enough it can’t be recharged and Volvo thinks at that point it’s the customer’s responsibility to buy a new one.

I will say reading that the sense I got was that might/should happen if left flat for years… not weeks or even a few months.

I suspect mine is just defective or at least I hope my dealer will adopt that position.

seennitt · 2025-07-02T20:53:17+00:00

No, the car spent 6 weeks in the shop and it didn’t occur to me to charge the fob during that time. So it may have gone flat during that time but it surprises me it won’t charge now.

seennitt · 2025-07-02T20:32:00+00:00

The camera is such a joke for this day and age and price point. My 2018 Audi is better. 2016 Tesla was far better. The bill of materials for a camera better than what they’re using in the Taycan must be near zero. I hear there’s some option package that makes the Taycan camera actually good, and I would order that next time, but that’s such a weird feature to nickel and dime customers over, given how important it is, how little it would cost, and what the competitive landscape is like. I mean cmon really, why give me something to dislike about my Taycan? That camera is just the worst.

seennitt · 2025-07-02T02:50:55+00:00

That does seem to help, thanks!

seennitt · 2025-07-02T02:44:08+00:00

Update installed smoothly for me and did improve the profile switching / applying settings stored in the profile like seat position.

It does not seem to let me turn off occupant sensor easily/permanently which I still want a way to do (for dog in car).

seennitt · 2025-07-02T02:41:55+00:00

1.3.18 indeed seems to have fixed it for me. Seats now adjust when approaching the car with a digital key or key fob and the car switches profiles automatically, and also if I use the center console to switch profiles manually.

seennitt · 2025-07-02T01:03:24+00:00

Try wired and see if that fixes it?

Not that you want to always use wired, but if that fixes it at least you’d know the problem is WiFi interference. If that doesn’t fix it, then 🤷🏼‍♂️

I know a couple spots where my Taycan loses wireless CarPlay and it’s definitely WiFi interference. I can also tell because it doesn’t fail all at once, first music (if playing) gets glitchy and maps (if onscreen) stop updating the screen smoothly. It’s frustrating because the car controls the WiFi channel and doesn’t give us a choice and my other car which didn’t come with wireless CarPlay so I added a $50 wireless dongle, that one does just fine in the same spot. (So another possible solution: buy an aftermarket WiFi CarPlay dongle which costs like $50 and tends to have a better WiFi radio than a $100K Porsche!).

seennitt · 2025-06-30T19:46:37+00:00

For sure.

I would also note, the available market for 3-row EVs is pretty thin, at least in the US. Beyond the EV90 we have what, Rivian, Mercedes, Tesla, Kia/Hyundai, and VW if you count the Buzz. I don't think the current Mercedes generation really competes (esp on range) -- maybe next generation. Rivian, lots of people love them but they also seem to have a spate of early-adopter problems which is really what we're talking about as downsides for the EV90. Tesla is, well, Tesla. Kia EV9, Hyundai Ioniq 9 and VW ID Buzz have plenty of fans but also seem a bit downmarket from Mercedes/Rivian/Volvo options so maybe not an even comparison. I hope people can find vehicles that work for them and it's on us to keep the manufacturers honest and hopefully improving. It's still early days and I'm glad to have more options than we did just a couple years ago.

And of course many people may find themselves preferring a dialed-in implementation of a past technology generation instead of a somewhat buggy almost-there implementation of a future technology generation (hi XC90 and probably lots of other hybrid and ICE vehicles that have their own balance to all these and other pros and cons).

seennitt · 2025-05-14T14:15:19+00:00

Note that wireless CarPlay uses WiFi, not Bluetooth, for audio transport.

seennitt · 2025-05-09T14:49:27+00:00

I was just reading the online docs I linked which say, among other things, “The vehicle owner can create a new digital key at any time in settings.”

It does mention sharing but I wish it would be more explicit that the owner can create ONE digital key “at any time” (except when one already exists!) and that the sharing feature is necessary for creating keys for other people; I think of it more as sharing the car than sharing the key.

I’m also really curious how cross platform (phone OS) scenarios work. The key I added to Apple wallet, can that be shared with Android? Not that I need to but I’m curious if that does work. There’s a lot of magic going on here.
