Recall 23v-840 Replacing Cell Block Module on High Voltage Battery

[fredhouston]

I received notice for this recall. My service tech said it might take 2-3 months in the shop to fix when the repair is available. Anyone have any other information on when the repair will be available and how long the Taycan will be in the shop? Thanks.

Man alive, 2-3 months in this day and age is just ridiculous - any idea what amount of this is waiting on parts vs actual work on the car?

Where are you located

 

[fredhouston]

I'm in Houston. The advisor said they have to drop the battery out of the car and there's one guy only who can work on it. No idea how accurate the advisor is...

Yes, but have you seen Porsche's newsroom today?

As I've related in earlier threads, when my battery modules were replaced, they had to fly in a certified Porsche Battery Technician from Atlanta. He said there were only 11 in the US. The delay is probably due to getting a certified technician - they are the only ones that can work on the battery. Hopefully they've trained a few more in the last year...

Your 2 -3 month waiting time is part of Porsche's HV battery repair process.

"High-voltage battery repairs at Porsche Centres - 11/04/2022​

Customer-oriented while saving resources at the same time: Porsche introduces its multi-stage service concept for high-voltage batteries. "​

Your months of wait for diagnosis, repair authorization from Germany, repair parts availability/transport/receipt, and the arrival of Herr Dr. Batterie-Meister's flight will hopefully resolve your Taycan's problem while saving Porsche resources at the same time.

However, since tasks such as spark plug and oil changes are no longer relevant, the scope of maintenance is likely to be reduced by around 30 per cent, as initial indicators in relation to the Taycan reveal. In addition, the electric powertrain, including the high-voltage battery, is completely maintenance free.​

Having to wait months with an inoperative car to have a problem diagnosed and repaired is not what I expected from Porsche, but it seems to be the way the Porsche battery repair process works.
POSIWID.

The HV battery is maintenance free but eventually will require replacement which I'm told takes approximately 10-12 hours which is roughly $2500 to $3000 in labor alone to replace just one module. I believe there are 13 modules in my base model 2021 Taycan and each module has 12 LG battery pouches. It does seems Porsche may repair under warranty individual modules by replacing failed or underperforming battery pouches but more likely simply replace an entire module with a pre tested one to minimize the time to repair the vehicle.
After 8 years or 100K miles it is more likely that at least several modules would need to be replaced to gain back range to be reasonable unless the old modules prove to be a fire risk.
Porsche must contend with the need for owners to replace entire HV batteries for the same or less than the cost of a base ICE motor which is approximately $25K. An ICE motor easily lasts 20-25 years and 200K+ miles so if HV battery packs must be replaced after 15 years or less they cannot cost $60K+ on a base Taycan. This would make the base Taycan a disposable car no matter how good it looks if the main battery either has lost 50% or more of it's range or worst case must be replaced due to safety concerns of batteries after a certain age. I hope Porsche would never let this happen because it would destroy the brand if even well kept vehicles become worthless at some point in time when the cost of an HV battery system is far more expensive than even the most basic ICE motor.
I have to believe there will be lower cost alternatives to repair or replace HV battery packs/modules in the next 5 or 6 years since there will be a huge number of EVs with batteries which need to be replaced.
I was aware of a Tesla Model S which cost $7.4K per battery pack for 5 packs in the Model S for a total of $37K all-in.
This was done after 300K miles on a ride share car after 3 years of use. Expensive but not outrageous for a $110K vehicle but if what I'm seeing on this forum and elsewhere that the Taycan could cost twice that amount! This would be very disappointing and lead to Porsche's EVs being branded as disposable since it would be foolish to spend $60K+ after 8 or more years on a vehicle which cost $100K new.
It was a bit disconcerting that the sales people at Porsche strongly suggested I should trade-in the vehicle before the battery warranty expires because they said I don't want to be responsible for the battery once the warranty expires.
I guess we'll see as we get closer to 2028 when my warranty expires...

Did you have the recall I noted or battery failure ?

I had one, possibly two bad cells in the battery - likely bad from the start and they were replaced. Noticed it when I had a significant decrease in range, and dealer couldn't see a problem. Once they ran the car down to 10%, they were able to see the error code.

I'm hoping if I encounter a battery failure that I'll be lucky that I live near Porsche of Newport Beach. My service advisor just told me they have everything to do battery module repairs or complete battery replacements. They have the trained staff to do these repairs so the only delay in repairing any HV battery is getting the parts from Porsche in Germany.

I've gone thru this process and there are some really important things that you should check w/ the dealer first.

1) Have they ever done this repair in the past and if they are fully certified to perform the repair.
2) If they are not, that means the shop will have to first get all the necessary equipment before they can schedule for a battery specialist to come in.
3) When all the parts arrives and the specialist is scheduled, it takes about 3-5 days to do the repair.

Because mine was the first car that my dealership had done, it took almost 5 months for mine. Feel free to PM me for details.

When I bought my RWD Taycan in Los Angeles two years ago I was told by the Porsche outlet general manager that California law supersedes the Porsche battery warranty and provides a 10 year warranty. Apparently this is not the case, which is quite surprising and, frankly, disappointing. From California Air Resource web site:

I agree w/ the comments about the risk of "bricking" otherwise perfectly fine EVs after, say, 100,000 miles due to the high cost of battery replacement. Because of the low cost of other service aspects of EVs, it doesn't seem unreasonable to pay, say, 25% for a new battery system every 10 years if the expected life of the car is in the neighborhood of 300,000 miles. Otherwise it will become yet another ding (a big one) against EVs.

I just had my battery replaced (cell 6 dead). It took a few weeks to get the battery from Germany and then a few days to hook up. I think this will become faster as more batteries are stored here. My 2020 was running but getting the big red warning and dying once in a while. Now I’ve replaced my Porsche EVSE with an off the shelf charger which works fine...an Emporia Level 2. Btw this was all done under warranty.
