Porsche Ordered to Buy Back Taycan That Charged at 9.6 kW, Not 11 kW

[Briguy]

I am not advocating anyone else follow my path but for Canadian owners who want more information and documentation to support a similar claim under the CAMVAP system please let me know. I have no expertise in class action matters, but I expect that the issues here would likely be effectively pursued via a class action. Not likely resulting in buybacks but very possibly in damage claims.

Again, not encouraging anyone to be litigious about this. Just trying to be factual.

I have a similar issue on my 2022 CT 4s that I don’t care too much about, but it can be concerning.

I have two AC chargers at home: the 40-amp charger provided by Porsche in the garage and an outside 48-amp Autel charger. I mostly charge in the garage at 40 amps and get an 8.9-9.0 kW charging rate. On the charger outside (48 Amps), I was getting 10.8 - 11.0 kW.

Lately, I only charge at the rate of 9.0 kw using the stronger charger. When I plug it into the EV6, I get full charging power at 11 kW.

I realized this issue since the OTA was installed this year (WST2), related to charging. I read the description of WST2, and it relates to 11 vs 9.6 kW, but I’m not sure.

Any insight?

It is a WSS4 that caused the rate drop from 11kW to 9.6kW. I am confirming this along with several others on the forum.

WSS4 = charging‑system reliability update (onboard charger / AC charging).
WST2 = PCM / infotainment / navigation / connectivity update.

Porsche deliberately chose to mitigate their own design-related reliability risk by reducing value to the consumer.....post sale. They should not be allowed to get away with this without compensation. It's subtle in the tactic they used but nonetheless completely unacceptable.

He got 90% after driving it for 2 years, that's a jackpot win financially.

Too true considering massive depreciation we have suffered on Taycans

Although for many owners the reduction in level 2 charge rate is rarely in issue, it is a downgrade, and I’d like to see the charge rate restored. If not, a good resolution would be to extend the battery warranty to 15 years/ 150k miles.
I see it as similar to having trouble with one of the battery modules, and rather than fix it, they disable the module, leaving a lower capacity.
Similarly, if you purchased the Burmester option, and they have issues with the amp on many cars, so they retrofit the Bose system, since both have the same basic function, just a lower specification.
If this charging downgrade is permanent, it reduces value, the same as if they reduced maximum torque/horsepower to alleviate inverter failures.

There's nothing wrong with the battery though, it's not affected in any way.
It's the charger that may fail if the charge rate isn't turned down.
Still, the 11kW OBC is way more reliable than the 22kW one...

Same situation using an Emporia 48 Amp charger. OTA applied, but I still pull 10.8-11.0 kW. Perhaps is is just linked to the Porsche charger?

Nearly impossible to get 11Kw to the car regardless of the OTA.

Just a heads up @Briguy that the names and VIN are still legible in the marker redactions.

The most valuable part of the settlement is that you did not have to sign a confidentiality agreement. PCNA made a foolish choice to arbitrate and just not pay you off, along with a confidentiality agreement. Now every participant, who is irritated with the vast depreciation has a way out. Just plain foolish arrogance on the part of PCNA.

This is exactly the issue. An OTA update that cut your onboard charger from the spec/sold 11kW to 9.6kW, as shown in the arbitration.

They didn't mention Amps, but it's a reduction from 48A to 40A requested of the EVSE by the car, so your 48A Autel charger will now see only 40A draw from the car.

I can applaud your initiative and follow-through but in the end is it worth it?

"I will miss my 2025 Taycan..." — so, you got rid of a car (even though you really like it) because it charges roughly 13% slower than what the advertised rate is?

I do applaud you for sticking to your guns. Porsche/VW Group needs to learn to stand behind what they sell & deliver. I’m still annoyed with the “don’t charge beyond 80% to 85% to avoid damaging the battery if charged to 100% frequently and left at that high charge state.”
No other manufacturer had the balls to make that statement after the sale to protect themselves from rampant battery failures under warranty. By only charging to 85% I reduce my range which is already low which will allow Porsche to get past their 8 year warranty commitment since I won’t put 100K miles on in 8 years but I could have left it charged to 100% on a regular basis which would have likely caused cells to fail.
I only charge to 85% max because I love my Taycan and I have 3 other cars I drive too. I’m semi retired, don’t have any commute and only use the Taycan around town. I use it on trips rarely so mileage will stay below 100K for at least 20+ years. If I needed it as a daily driver I would have been very upset with being told after the sale that my range is now 15% less than I purchased.
At a minimum I would have wanted a 10-15% discount for the reduction in range they actually delivered.

Did cars in USA/Canada actually every reach 11kw delivered?

My taycan has not once charged above 10.2kw.

It’s definitely a precedent. Sadly, Europe and Switzerland have no such legal bodies.

But it could help people in USA & Canada to force porsche to actually deliver on what they advertise or settle in court

tldr; _ANY_ time the car shows you a charge rate > 9.6 kW it's charging at a rate faster than 40 amps - which means it's "using" the 11 kW capacity of the OBC…a charge rate of 9.6 kW "raw" would result in the Taycan showing a charge rate of less than 9.6 kW because of normal/expected charging overhead losses…9.6 kW is 240V @ 40 amps - 11 kW is 240V @ 48 amps - Porsche is capping North American Taycan's to 40 amps via OTA/Dealer updates…this limits the maximum AC charging rate to 9.6 kW "raw"…

details below…

10.2 - 10.86 kW is the effective charge rate at the battery (including overhead losses) when being fed a "raw" 11 kW (240V @ 48 amps) - the 9.6 cap is actually misleading - it's not 9.6 kw - it's a limit of 40 amps @ 240V - which ideally is 9.6 kW "raw" - this in practice shows up at the battery somewhere around 8.6-8.8 kW effective charge rate.

Yes the car could and did request 48 amps - you can see this in the 10.2 kW - and on some EVSE's they show the raw power "feed" at the EVSE which is 48 amps...

updated Taycan's (and the Macan EV) no longer request more than 40 amps in North American region because of an OTA update.

there is no question Taycan's used to allow 48 amps - there also is no question that Porsche for undisclosed reasons is capping North American charging at 40 amps…

the Cayenne EV is specified to be a 40 amp EV in north america, but porsche has repeated stated that it can charge wirelessly at 11 kW (48 amps) - it would be a sad joke in the Cayenne Ev can charge faster from it's wireless charging pad than it can plugged into a wall…but my guess is Porsche is as confused about those stats as they have always been about the Taycan's charging limits…

I documented the Taycan's original North American charging limits as 48 amps in Aug. of 2020 with this posting…it's taken 5+ years for Porsche to finally achieve clarity on the Taycan's North American charging rate/limiites - up until now it's been both 11 kW and 9.6 kW depending on the phase of the moon and who last updated the website…but until recently the actual cars being shipped allows 48 amp charging…this has all changed with the latest OTA updates…

here is my thread from Aug. of 2020 noting the 11 kW charge rate for my 2020 Taycan Turbo.
