New (Sept 2023) global stop sale on all Taycans? Recall APB2 updated Sept 11, 2023

[WasserGKuehlt]

Here's what I suspect is happening. Cars built before the new sealant was introduced aren't being recalled because they were built to meet existing standards. Cars built between Sept 22 and May 23 with the defective sealant were built explicitly to be "air tight" and the sealant has failed to meet that standard to 100% effectiveness.

I am not reading that from the NHTSA report, which simply describes the issue as "liquid intrusion". I recall several, older posts of yours describing discussions with your dealer, so it's possible you have access to additional information, not disclosed to NHTSA.

So what you're saying is Porsche calculated the number of pre-MY23 batteries expected to leak within their battery warranty is low enough that their battery replacement and possible fire liability is cheaper than a recall. For MY23 the new sealant is bad enough that too many batteries will fail, causing larger cost than the recall cost. Did I get that right?

That is how I interpret the NHTSA report, yes. The chronology of the defect seems to be:

before Sept '22: isolated cases of liquid intrusion, none in the US
Sept '22: attempt to improve battery sealing with "Teroson sealant" (v1)
Mar '23: batteries with v1 found with reduced insulation resistance (ie water ingress), outside US
Apr '23: same as above, within US
(around here): v1 sealant found insufficient, a "further enhanced Teroson sealant" should be added (v2)
May '23: batteries sealed with v2 ship, no further reports since then.

I'm reading the above to mean that a small % of ~MY22 (or older) leaked; the fix (v1) actually leaked more/at a higher rate. This was followed by fix v2. Because the v1 leaks occurred in the "wrong" country, they are issuing a recall to apply v2, rather than handling the failures on an individual basis. It's unclear if the recall was voluntary, or NHTSA made them do it behind the scenes.

It's worth noting that in October 2022 GM recalled Hummer EVs for a similar issue. That could easily have put this on NHTSA's radar

Audi recall chronology seems a bit more clear:

Has there been any further update? Have the checks at the ports started?

From various threads in this forum, apparently one car in Switzerland has been cleared of APB2, a few in the US have brought their car in this week but so far I haven't seen anyone say it's been cleared. I received an email from my dealer last night that the parts required (presumably the filter/valve at the back of the battery) would be shipped to them "soon" and they would begin working on our car as soon as that arrived.

Not that I'm obsessively following this or anything.

haha I'm in the same boat...GTS has been sitting at the JAX port since July.
Last I heard from Porsche was Sept 12:

"Due to a small number of past cases, Germany is having the ports check the batteries on all Taycans to make sure they are sealed properly and no moisture can enter. Parts are required for these quality checks and it seems there are delays with those parts coming from Germany. They did inform me they are hoping to get them completed in the next few weeks and are working diligently when they arrive."

Did your sales person tell you that, or did you get someone from Big Porsche to give you some info? Not surprised that there are delays resolving the delays.

It was PEC-ATL

Thanks. My car is headed there too, someday.

Well this is new and good to see. That message wasn't there a day or two ago.

 

[new2porsche]

any idea if cars coming off the production line in late Aug will still be impacted by this?

The cars with the potentially defective sealant were built from Sept 2022 through May 2023. So an August build is not subject to this recall.

Finally a bit of good news. The car's HV battery was tested today (apparently 4 hours in the shop) and passed. It should be released for sale in a day or so.

We may actually have a new car this week. Can't wait to find out what goes wrong next.

 

[summerlion]

Good to know there is actually progress being made on this. I have no expectation that my car will get sprung loose on its predicted date this week (according to TYD; the My Porsche app lists the next step as "unscheduled" which sounds more likely), but maybe getting closer.

I've been following this thread with interest. I've got a 2024 GTS, produced June 22nd, that finally arrived at the dealer here in Western Australia on 9th October (it takes a very long time for a ship travelling 18 knots to go from Germany to Australia!!).

Even thought the car seems to be outside the manufacturing period (post May 23) and not in VIN range, I was informed by the dealer on 20th September that the vehicle still needed to go through the battery pressure check. This has me under the impression that all new vehicles were now subject to this test prior to handover (or at least for some time).

Could that be right?

If so it's gonna be yet another handbrake on new vehicle deliveries.
