J1.1 Taycan High Voltage Battery Reliability Survey

[D00notD00d]

J1.1 Taycan High Voltage Battery Reliability Survey
How many forum members have had a battery module replaced (during a recall, or after a warning/failure).

J1.2 owners: please don’t vote!

Edit:
Former J1.1 owners: unless you know for certain that your former car hasn’t had a replacement after you sold it, please don’t vote!

EDIT 17/10:

Please vote accurately, not speculatively!

If you bought your car used and haven’t verified from its PCSS record whether its had any battery modules replaced, you’re a ‘don’t know’.

You’re also a ‘don’t know’ if you’ve sold a car and don’t know if it has had any battery modules replaced since you sold it.

Great idea!

Although the result is already interesting with only a couple of reactions. This poll is no presentation of real world situation at all.

Why not?

 

[Jasper4S]

Forum polls don’t really show real-world numbers. Only a small group of owners even visit the forum and bother to answer, so the sample is tiny compared to all Taycans out there. Plus, people who have problems are way more likely to respond than those with no issues, so the results get skewed. Almost all owners not on this forum will choose the 3rd option. “Unknown” they don’t even know about red or yellow circles, it is just a vehicle that happens to be a sexy vehicle we praise on this forum. They probably don’t even know about this forum

Of course - statistically, against c.140k sales worldwide, the forum result here is unrepresentative.

In their Oct 24 submission to NTHSA, Porsche estimated 2% of cars had a production defect. But since the defect surfaces over the service life (10-20 years?) I don’t know how Porsche could reliably model and extrapolate from just 4 years usage. There must be over 4m battery modules in the wild, in various usage conditions.

So the poll is the worst case scenario: < 18,3% has had module(s) replaced.
That's actually great!
According to the thread of Cris most batteries are perfectly fine so this poll is actually showing that.

 

[Jasper4S]

18,3 is a lot. Not something Porsche should be proud of. I think it is a tenth or even less of 18%.

To me 4 out of 5 batteries are fine - is not a great number, but 98 out of 100 is.

@Jasper4S You are right with your estimates, I think. Still interesting to poll and discuss here.
I'm with the 1-2%.
but probably don't ask @ct14garage

An estimation is just that, an estimation. They don't know, hence they recalled & installed new software in all 156k cars.

It's also sounds like a unlikely positive estimate; 2% of 156.000 cars sold would be just ~3000 cars. In the context of my dealer doing 3+ a week, and have been since last year, it sounds even more unlikely. And let's say this is a big service/dealer, so maybe others do less, but even with that consideration it still sounds insanely unlikely.

I remember there being a thread on the forum with info from PCSS with number of cars that went through a battery module replacement, maybe from @Tooney. The number was definitely bigger than 3000

 

[D00notD00d]

Has anyone had a double dip replacement?
Module replacement on more than one occasion?

Me.

First time multiple modules - 2 from what I remember, need to look at the extract from ct14.

2nd time just one module.

About 8 months apart. Both replacements were done out of the blue, no errors of any kind in the dash or any problems.

And probably I will get a 3rd intervention within the next 6 months, as range has went down by ~15% over night like 2 months ago (40-60km of range just vanished). Still no errors of any kind

 

[D00notD00d]

@chun - that’s an extra vote! Which makes 21% rounded.
I wonder if a full swap to j1.2 modules can now be negotiated when a failure occurs.
The extra labour cost per module is probably not significant.
