The (expected) ARB7 recall letter comes (my THIRD open recall...)

[Tooney]

I wonder, is this a recall the stealerships are equipped to perform, right away?

it doesn‘t appear to require any physical parts to wait on, unless the analysis shows faults.

The TSB of instructions to the dealer for ARB6/7 remedy has not been posted on NHTSA. Software diagnostic software not expected until first quarter 2025.

I got Arb7 recall yesterday - called dealer and they made an appointment for Dec 12th. I have open recalls for Brake issue and charger replacement .

 

[Tucson_Jim]

Yep. Got mine yesterday as well. Add that to the brake line recall (parts pending).

Maybe update your app?

The app is fully up to date! I called Smart mobility and asked. But was informed that my car did not have the necessary HW installed!

If you disable privacy mode in PCM & app, they will be able to gather data.

With a MY20 model also, they informed me of new recalls

Charging to 80% is a recommendation, not enforceable at the moment.

I have never had Privacy mode enabled! Smart Mobility have been able to see the vehicle. I have Tronity enabled and the car reports in. Also to ABRP.
I have had the service guys confirm all these settings many times over. So my early model clearly will not report anything.

I have regularly been informed about recalls, that is not the problem.

Good idea. I would advise everyone not to delay the usual recalls, because when dealers get slammed with ARB5/6/7, everything else will be back burner.

Do not forget to ask to apply PSM Update along with the Brake Hose replacement and then since it includes free Brake Fluid Flush do not do it for another 2 years.

Basically, when writing thing up say, I need the following done:

APB6 - Charging Cable replacement 240V
ARB0 - Brake Hose replacement with Brake Fluid flush
WPK0 - Reprogram PSM control unit (improved braking performance)

ARB7 - not in scope for now but limit charging to 80% is the remedy at the moment.

I start to wonder if the guy in 2020 or 2021, that was reporting that Porsche knew that all Taycans battery had a problem, was correct. He got slated from every corner but now……? You start yto look at old posts?

WPK0 applies to a limited set of Taycans. When WPK0 was released in US in May, 2024, about 3400 US Taycans were included. https://static.nhtsa.gov/odi/tsbs/2024/MC-10254160-0001.pdf
Brake lines recently replaced in my 22 4S. Not included in WPK0 and no PSM programming listed on service sheet.

Interesting point. I guess I am lucky it showed up for my VIN and they did it and while I was pretty happy with the braking, I knew it could be better, and after this update, it is just perfect with full confidence that at low speeds below regen limits my physical brakes provide very smooth and confident braking.

My point to anyone who is going through ARB0 to just ask to see if WPK0 applies as my paperwork shows it not as a mandatory recall but "VOLUNTARY SERVICE ACTION". The paperwork states that the dealer had to check if this campaign applies to my VIN.

For cars under ARB7 there is no limitation on the charging ceiling. Porsche has OTA data and there is currently no indication of a battery fault. For ARB6, where no OTA data is available Porsche is recommending 80% "as an interim remedy". I'm referencing my ARB7 recall letter and Safety Recall Report 24V-732. Might differ outside the U.S.

So can we translate ARB7 as:

- We will check the battery remotely. If it sucks we will add you to one of the prior battery recalls.
- Next year we will install new battery management software.

If I’m right then I guess this recall is neither cause for alarm (yet) nor actionable.

Unfortunately that is exactly how I read it. "Right now we don't think your battery will catch fire but if things change and it looks like it might we will let you know." Considering the delay in sending out the 3 ARB recalls any notification from Porsche about my possible pending battery fire might just arrive a little to late to save my house.

I thought the letter we all just got in the mail is old news per @Tooney, as he posted a newer letter that we should be getting in the mail next that was scrambled but showed ARB7 and 80% limit as remedy. I was wrong since the scrambled recall is ARB5 with 80% limit as remedy. My understanding is that if you are under ARB7 and Porsche determines via OTA that any module is faulty, then it automatically goes into ARB5 at which time the instruction is to limit charge to 80%. How safe is it to charge over 80% if you are in ARB7?

I guess you are safe to charge over 80% until you aren't. Porsche will see the deterioration via OTA monitoring and then notify you in 3 or 4 months that you have a problem? Certainly took their time getting the ARB recalls sent out so I'm skeptical that being notified that your car has just qualified for ARB5 will be fast.

I received the ARB5 letter about a month ago, and have been on the 80% max charging since. Feels like the car is constantly plugged in which is a bit of a pain.

Car is booked in on the 6th Jan for the initial diagnostics which the letter says can take up to 5 days. It says if no anomaly in the modules is found then the car wil be returned and can be used as normal, but based on input from this forum it appears there is no chance that will be the case and it will require replacements.

Funny, if I put my VIN into the Porsche recall checker it comes up as no open recalls, however clearly not the case.

Out of interest, you guys that are receiveing ARB6/7 correspondence, have you already had the ARB5 work carried out?

Update, I am in the UK not Turkey. Not sure how to change that profile flag...
