High Voltage Battery Recall EXPANDED - ARB6 & ARB7

[Chalper]

I also received this earlier - all three local dealers are clueless about it. I called Porsche directly, and the person I spoke with put me on hold to talk with his manager before commenting. He said that even though the email makes it sound like remote battery monitoring is available now, we are still waiting for a date from Porsche. However, they hadn't seen the email before I forwarded it to them, so perhaps there's more to it, and one of you will be able to get better news from Porsche.

"To remedy the safety recall, Porsche is preparing a software update. This full remedy is not yet available. ‌ As an interim remedy, Porsche is able to remotely monitor the health of the high-voltage battery in your vehicle if you enable remote battery monitoring.‌"

It clearly says: " To remedy the safety recall, Porsche is preparing a software update. This full remedy is not yet available. "

So it is just ARB7, in interim remedy.

Just got this email. No new software appeared ready for download. I tried calling my service center as suggested but of course it's Friday afternoon and no one answered.

Well you did better than I did. My email was identical to yours except none of the steps to enable anything were included. Not that it matters since the "remote battery monitoring" tile is gone from my app.

 

[BluBaby]

I think they sent the cart out without the horse! Sad really for a company like Porsche.

I received that email as well and followed the steps for remote monitoring. I have the app on my phone and privacy is disabled in my vehicle…but how I do download the software or otherwise enable the monitoring? My car already had privacy mode off but was ARB6 status. This is so confusing.

It should be automatic at a time TBD. Need a good connection AND the help of the Porsche gods....just wait!

Thanks but what is the “connection”? Is there anything I need to connect to?

Your car normally connects to the internet (as long as signal is strong; unlikely to be strong in an underground garage for example; driving about normally should give you exposure to a strong signal; sim card is Verizon BTW). The car's built in internet connection is what allows you to get OTA updates including routine stuff (e.g. map updates).

The email is confusing at best. Didn’t they say they have been remote monitoring arb7 for months now?

I tried to get clarity from PCNA and my dealer service neither could give a straightforward answer.

I'm not sure if this applies in USA, but in europe it would:
As long as Porsche advised you to limit charging to 80%, and you were informed about the recall, and you didn't follow their advice, they have plausible deniability. So they wouldn't be responsible in any way if your car burns down while having 81% battery - i'd argue they'd rather spend 100k to prove that you had 81% battery, rather than pay you 100k.

And your insurance may claim the same. I would safely assume, that if any taycan burns down, any involved party will try to avoid as much as possible paying out any damages.

Yeah it will be different here.... What letter? I didn't receive any letters. They literally have no documentation other than sending, and sending is not confirmation of receipt. I have no idea what they are talking about, further, if porsche has a hard limit they can put a hard limit on the car and not let me, a non-technical consumer, try to navigate their complexity. The burden is on the producer to fix.

Can you imagine you're in a court room with a jury, who will be way less familiar with technology than you or I (think, my mom for example !) who has to sit through some engineer showing them how you limit charging to 80%... there is ZERO chance porsche convinces them its impossible to expect the consumer to do it... I mean all you have to do is 'accidentally' hit the direct charge button!

Further, this software patch does fuck-all. It's simply saying "OH, your basement has flooded" after the fact. The fix is a new battery.

In the US, this won't stand the test of the courts... Porsche knows they have an issue but all these actions are kicking the can down the road. I'm near 100% confident all .1 cars will receive new batteries.

Its also why they will buy back cars and have been doing so quietly for months, at least in CA which as very consumer friendly protection laws.

Ironically, seconds ago I got this letter from Porsche: seems like progress?

The only progress is kicking the real solution down the road more.

I would think that our warranty of 8 years on the batteries is currently in force- The battery is clearly defective - not able to perform up to the manufacturers claim e.g. you cannot charge up to 100%. I am sure that there could be a class action lawsuit that would force Porsche to remedy this.

This:
"[...] Porsche recommends you set the charge settings so that the battery is charged only to a maximum of 80% [...]"
... is only for a Taycan that has neither enabled remote battery monitoring nor had the battery checked out at a dealership.

I didn’t initially read the email that way, but now that I’ve re-read it I think you’re right.

Looks like I can go back to the normal charging rate of 85% when home.

I don't know if that is true - at least currently- the current limit is 80% right now. There is no remote battery monitoring software- the recent OTA sets you up to have remote battery monitoring when it becomes available (OTA, dealer visit who knows)... and/if/when we get the software it remains to be determined if we can charge up to 100%. Anyways it looks like there is someone who is starting a class action already - https://www.classlawgroup.com/consumer-protection/porsche-taycan-lawsuit

Although Porsche certainly could have structured that message more clearly, the 80% recommendation (which is definitely *NOT* a "limit") is only for those who have neither enabled remote monitoring:

"Until the health check can be carried out by a Porsche Center, to help prevent potential damage to cell modules, Porsche recommends you set the charge settings so that the battery is charged only to a maximum of 80% until the full remedy is available."​

That paragraph is under a section heading of:
" PORSCHE CENTER OPTION"
... which is clearly an alternative to remote monitoring (as it starts off with "If you prefer not to have your battery monitored remotely [...]").
