I'm expecting a poor / no offer from Porsche GB over the next 48 hrs or so.

After recieving that, ill formulate a response and plan of action.

I read the thread re the Macan EV as suggested, and it appears the member got his finance cleared, and a discount on a replacement car.

I just want out, I can see where my long term ownership experience is headed with this car.

I’ve not been able to find any detail describing the j1.2 cell and monitoring changes. Grateful if you could share some references. How are they different?

Porsche described the various J1.1 manufacturing defects as
a torn anode tab, a folded cathode tab, a peeled-off cathode or a double production topic pouch crack’.
They seem common items.
Those issues were fixed when they switched to the NMC811 chemistry afaik.
At least what I heard from my Porsche contact is that the facelift is not affected by those.

They would say that, wouldn’t they. I also don’t have hard facts which I can reference, but my opinion is that the j1.1 cell problems were component quality and/or assembly issues that could apply to any electrical component. The j1.1 issues were not because of the chemistry. Only component quality and/or assembly changes could reduce the likelihood of manufacturing defects.

My understanding… please let me know if I have misunderstood.
You are not Porsche GB’s customer.
Porsche GB bought and imported the car from their parent company Porsche AG. They then sold it to your supplier, who later sold it to you.
I assume you have a sales contract with the dealer who sold you the car? If so they are responsible for compensating you, not Porsche GB - your consumer legislation beef is with the company that sold you the car, not Porsche GB.
Whatever Porsche GB do or don’t do to compensate whoever they sold the faulty goods to is not your concern.
Your refund case is with the company named on your sales contract. Don’t let them deflect responsibility.

IIRC even the last J1.1 cars from 2024 do not have ARB6/7.
Most of those issues were corrected by then.

We shall see how it goes, but J1.2 has been out for 2 years and if there were a lot of these problems, we'd also hear a lot about HVB issues by now. But we haven't.

Porsche has been aware of the issues for quite some time, and by now they are also rectified.
They pushed the recall years into the future until some cars started to catch fire and they couldn't sweep it under the rug anymore. Porsche was aware of the defects years ago.

The thing is that it's not just chemistry, the new modules have a different structure to the old ones. So that means a new production line and so on.

You need to go in pleasant, but very firm on this imo.
Tell them what you want exactly and leave them in no uncertain terms that you will not be palmed off and you will have no problem in escalating things.
They need to be more concerned about what is to come if they don't sort it now.

We have got something similar with insurers/repairers/courtesy car at the moment on my wife's BMW.
Awaiting their call this morning......I have got a list of questions that I already know the answers to. I will also tell them I am recording the call at the start (always wakes them up).

Good luck!

The dealer have put in a rejection request with porsche GB, he thinks they'll deny it.

They've offered market value plus goodwill, so a normal trade sale, with a goodwill sum from Porsche and a top up from themselves toward a new car.

I've made it clear to him, my next step is the finance company (if he can't sort a resolution).

Ultimately re VW finance, im their customer and they own the car.

Untrue.
The entire j1.1 production run from 2019 to 4/3/24 (1/2/24 in America) was recalled under ARB6/7.
If Porsche had sufficient evidence that the cell manufacturing risk did not affect later J1.1 cars that wouldn’t have been the case.

The J1.2 was not part of the recall though. But the problem was known at Porsche for a long time.

ARB6/ARB7 is just one of the recalls, there are others as well.
The ARB6/7 was a software update for all the earlier cars to make the monitoring of modules tighter, it applies to all the pre-FL cars not part of the actual recalls that had known defects.

Specifically:
Porsche Taycan Intermittent red warning J1.2 1768219206778-x3


The cars that were 100% considered problematic are outlined here:
https://static.nhtsa.gov/odi/rcl/2023/RCLRPT-23V840-4026.PDF
Here:
https://static.nhtsa.gov/odi/rcl/2024/RCLRPT-24V215-9738.PDF
And here:
https://static.nhtsa.gov/odi/rcl/2024/RCLRPT-24V217-1217.PDF

You can see it's a pretty low number of the overall population, and pretty much non-existent in 2nd half 2023 already. This is because the issue was pretty much fixed in 2023, but of course the older stock wasn't, and some of it found it's way into cars produced late 2023 and early 2024.

This also agrees with the information I have from inside Porsche...

My WP0AA2Y16PSA12259 VIN doesn't appear to be within the range (WP0AC... to WP0AD...), but I did get the ARB6/ARB7 recall letters.
What is the correct way to read the range?

Mine is a very early j1.2, the dealer had it in May 24, not that it should make any difference.

Initial Porsche recalls were based upon analysis of a sample of logs. The sw accuracy is unclear.
In the end, by the final recall, Porsche could not convince UK, EU and USA regulators that the entire j1.1 production run was not at risk. Those guys need more than anecdotal hearsay.
But yes, only a small percentage actually have the problem.
J1.2 production numbers are a lot smaller.

Yeah, I guess they could not hard prove that the other cars could not possibly have the problem, so they had to recall everything. As it should be.

But it seems they were able to convince the regulators that by using pro-active monitoring it is possible to detect the problem before it occurs.

That said, the initial recalls were not only based on sample logs, there were manufacturing issues detected in certain batches and then all the cars from those batches got recalled immediately.

@d00d (the original D00)
Check the subscriptions in your Porsche account.
UK cars come with a 10 year basic ‘connect care‘ subscription which supports updates.
I suspect the same will be true globally.
https://connect-store.porsche.com/offer/gb/en-GB/taycan_2026/products

Note eventually the entire j1.1 production run from 2019-24 was recalled.
Previously, cars with sufficient use and mobile connectivity were monitored remotely, then, if required, had cell replacements, and later, the monitoring sw updates. Cars that were not contactable were recalled for dealer visits.
