What doesn’t mean for buying that feature and now is not longer available? Wonder if Porsche will issue some sort of compensation

As I read the TSB, it means if your Taycan has a 22 kw OBC and the OBC fails and needs to be replaced, then the replacement will be 11 kw OBC.
It is not a recall of all 22 kw OBCs. Nothing in the TSB about compensation.

I got the part about the replacement but when you pay extra for option, and it is not longer available or functional , the least would be to reimburse you. I am pretty sure we will hear soon from someone

A porsche mug

maybe an insulated one

maybe unique design, “22kw no more”

at least the few people that posted having this happened, didn’t get any real compensation

This also clarifies the rumors that 22kw is coming back, as it’s definitely not coming back

Being the first to face that problem I can tell you that there is a monetary compensation in Germany. I am going to report its amount once the details how I am going to receive it are clear and the money is on my bank account.

In general I think there are customer protection guardrails, but this might vary depending on your country. The amount of money in the discussion is not a band-aid, but to be honest I would rather have prefered to not need to deal with the downgrade. I have used the 22KW charger a lot, it adds a lot of flexibility, it was one of the reasons I bought the car.

For Porsche I really hope they are going to commit into to this topic, it seems like it would not be too hard to fix the design flaw and reoffer it again. Having no 22KW charger for a luxury EV seems wrong to me.

So what's next, the Turbo S front motor/inverter not available anymore, so anyone needing replacement gets downgraded to RWD Taycan by disabling the front motor and Porsche considers it a fulfillment of the warranty? Maybe if a battery fails, they just give you a smaller one because the original capacity is no longer available, and they think it's ok? I wonder if they would accept the same for monthly payment, someone saying they no longer have US dollars, so will pay the remaining payments to Porsche in Taiwan dollars at 1:1 exchange? "Dear Porsche Financial Services, I no longer have US dollars to pay you with, but will instead substitute each US dollar with a Taiwan dollar".

I have the 22kW OBC (on my 2nd one already), so this will be interesting. They sold me a car with a specific performance of the onboard charger, so they are obligated by law to provide warranty replacement that meets original manufacturer specifications, as well as provide spare part replacements for some years after the warranty. I'd be ok if they refund me the whole price of my car in USD and allow me to pay in them in Taiwan dollars instead, at 1:1 exchange (same as they think 1:1 exchange of 11kw vs 22kW OBC is fair, one dollar should be equal exchangeable to another dollar with "lower spec" just the same, right?) - also ok if they just sell me a new Porsche EVs at USD prices but accept Taiwan dollars at 1:1 exchange.

You can absolutely force them into a buy back with a lawyer; but most people are not willing to go to court, and porsche relies on that.

I’m curious what will happen in the next 2-3 years, as for sure there will be people displeased by this that are willing to go to court.

Or maybe they will update their warranty policy to claim that the 22kw charger is no longer covered, at this point you can expect anything.

"Obligated by law" - what law?
"replacement that meets original manufacturer specifications" - is meeting original specifications a specific requirement of the law?
"warranty" - required only during the manufacturer warranty period?
Is a violation of the law a civil matter, or is enforcement by some govt agency?
If violation is a civil matter, is pursuing it in court for a part costing perhaps $2200 (or for 'damages') cost effective?

I'm not opposed, just wondering if a legal remedy is practical.

Interesting. my ct4 has the 22kw charger and it failed earlier this year. the car was out of service for over 2 months waiting for the part. they did replace it finally.

I"m 100% sure in the US market. you would get financial compensation if this happens under warranty, at least the cost of the option and likely some consideration for inconvenience. Dealers won't handle that though, you'll have to work with Porsche NA.

"Obligated by law" - what law?

Legal obligations vary by jurisdiction. Various jurisdictions have different requirements for replacement parts for cars. US does not have post warranty part replacement requirement but has warranty laws such as the Magnuson Moss act which you could use by claiming that Porsche is refusing warranty repair if they can only provide a part which performs at 50% of the original spec. EU is currently trying to pass 20 years car parts availability as part of their right to repair and reducing waste efforts.

"replacement that meets original manufacturer specifications" - is meeting original specifications a specific requirement of the law?

Usually yes, in warranty coverage laws. This is to prevent manufacturers replacing parts of your car under warranty with cheaper, lower performing ones. An extreme example could be you buying a 911 GT3 RS, you bring it in for repair under warranty, they give you a Toyota GR Supra and tell you how lucky you are because they replaced every single part of your car (just with less capable parts), you are in fact getting a new car!

Is a violation of the law a civil matter, or is enforcement by some govt agency?

Again, depends on the jurisdiction. Some countries have government bodies regulating it, others don't.

If violation is a civil matter, is pursuing it in court for a part costing perhaps $2200 (or for 'damages') cost effective?

Lawsuits are rarely practical - usually takes more time and money than you win (then you can turn around and sue for costs, repeating the cycle). Suing for $2,200 would fall under small claims court in most jurisdictions, which actually can be more practical. However, in this case I would argue it's not a matter of $2,200. If I'm still under warranty and Porsche is trying to fit my car with parts reducing the car's performance to 50%, that would likely be considered failing the warranty, which may require them to buy the car back from me (again, different jurisdictions have different laws, CA for example has very generous lemon laws). Post original manufacturer's warranty in the US unfortunately would get much tougher.

Personally, unless it's for the principle of it, I would not bother with lawsuits for which I have less than 75% chance of winning at least $25k. I have done this once, I won $25k, but would still dread doing it again. It's a time, money, and soul sucking experience (with brief pleasure moments when you stick it to the other guy ). Now, if I think I have a 75%+ chance of getting $200K back from Porsche, I'd do it, both for money and the principle of it. I probably would consider settling for something like a new, unlocked J1.2 battery to offset my 22kW OBC usecase (if I can put more electrons in the battery in the first place, I might not need to recharge it as fast on those days when I need to do more than current max range of the car). At the very least I would expect a triple port, load-balancing 19.2kW DC charger installed in my house (replace the tripple 19.2kW AC setup I have in my garage) - this would not allow me to charge faster outside of the house, but for my usecases, at home 19.2kW is the primary driver for ordering 19.2kW cars (both EVs in my garage have this option).

Or maybe they will update their warranty policy to claim that the 22kw charger is no longer covered, at this point you can expect anything.

Post sale update of the warranty agreement would easily be fought in court. Heck, that by itself might make it easier to force a buyback.

Don’t be rediculous.

There’s no way it’ll be insulated
