FYI: Main Battery Replacement Needed!!!

[whitex]

About 24-25 kg different approx 22kw 31 kg vs 11kw is only 6kg excl. thicker socket and cables. I guess most from the larger heat release elements and casing.

That is a bit. Where did you find these numbers?

This thread is as informative as it is entertaining. Thanks to the OP for sharing the experience and timing. A couple of things were said that are kind of glazed over that should at least cause pause for all of us as owners.

First, I'll preface it with I had my own failure just over a week ago with the same result - new high cap. battery requirement.

Second, and more alarming to me is how the car doesn't necessarily track the faults for the tech to read and test against. The notification on the dash sounds like its about as helpful as the check engine light from 30 years ago. Moreover, this can sometimes lead to a fix by doing the Porsche version of a CTRL/ALT/DEL - and the tech won't have a record of the issue or know what might have caused it. So on the one side a simple reset, and on the other end a complete battery failure that bricks your car. Both give the same response on the dash and symptoms - there are of course some options in the middle of that spectrum too.

Personally, I'm not all that comfortable with taking the car back. It's a first gen 2020; these issues aren't isolated or as infrequent as 'winning the lottery'. There are 3ppl just in this thread with the problem from Dec 2022.

Yes cars are mechanical and will have failures. Nothing as complicated as these machines will be infallible. How this is handled though - not all that great. The OP had to ask 'what parts' in the repair; another speaking up was given a time quote of 60 to 90 days (which is the same as mine). And the consensus on this thread other than those actually experiencing it is 1. don't complain that you drew the short straw and 2. you should be so lucky to have your battery replaced under warranty.

I'm trying to write this without it sounding salty, but...that is how a cult acts. lol.

PS - my dealership is still short on loaners with none in sight. I contacted PNA and they said I could rent a car at my cost and they would 'consider' paying my fees but only after I incur them and submit. Honestly, this is not how a high end brand should operate.

I do agree, it should not happen and the way it seems dealt with (at least in US) seems unreal.
it’s like your worst nightmare that can happen with an 150-200k purchase.

I couldn't agree more, when you experience the issue and the elongated resolution, perspectives will change. I experienced the same issue recently as many others have (and the numbers are growing at my dealership). One Module went bad that was eventually replaced along with the 12v battery. It took over two months with no loaner and the response from Porsche NA has been extremely disappointing to say the least.

Things go bad for sure, especially on an early model but its the customer service and resolution that counts, Porsche has a growing issue that they need to address.

We read regularly on this forum that somebody has a battery failure with a 2020 Taycan, with the old chemistry.
I am wondering: did anybody hear of a 2021+ car (with the new chemistry) having a battery failure ?
Could it be that Porsche is doing a full replacement on 2020 cars, but only replacing modules of the battery on the 2021+ cars ? It would make sense if they think the 2020 chemistry is bad.
Are there any examples of that, that proof this theory ?

My 2 Yr Old Taycan Turbo S died in the driveway (after simply backing it out of the garage) with the dreaded "Electrical System Error" (Red).

The car would not move (although the Console, Nav, etc appeared fully functional). Seems other folks have had the car towed, but I don't look kindly to some guy dragging my car up on a flatbed. I did find a report that sometimes the issue will "go away" so I waited, and waited, and finally got the car back into the garage. Porsche wanted me to simply have the car towed to them, but I said I would rather risk it and drive it (if possible) - as it could always get towed if that didn't work out. I successfully drove the car to them where they have now had it for a little over a week.

They pulled the diagnostic codes, and in conference with technicians in Germany, It has just been determined that it needs a whole new main battery pack (which must be shipped in from Germany). Based on folks who have reported similar issues, I'm expecting the car to be in the shop for 30 days or more. :-( The dealership gave me a Cayenne Loaner so they are covering the outage to the best of their ability...

I'm on my 5th EV and never had ***ANY*** battery issues with my Tesla (MX), BMW's (i8, IXM60), or Chevy (Volt). We all know about the issues with the 12V battery (that required replacement), but it also appears the main battery (and/or onboard charger) may have its own problems: https://www.teslarati.com/porsche-whistleblower-taycan-battery-charger-fires-coverup/

That sucks! Mine was in the shop for over 3 month just to replace a single module.

Just went back to the shop today to sign an official 1 year full warrenty extension on the car as a thank you for being extra patient.

What do you mean by old chemistry, I did not hear anything about a change of battery chemistry/ cell supplier.

Sorry to hear about this. I had the exact same thing happen a month ago. On 11/14 it was towed to the dealership. After some consultation they decided to replace the entire battery - was told it ships as a complete unit with the installation hardware needed. My car has been there one month now, and unfortunately we still have no ETA on the battery.

I’ve talked to Porsche NA twice in the past week, but I’m still waiting for my “case manager” there to tell me how they are going to make this right. Very disappointed and likely will be chatting with an attorney about how what sort of compensation I may be entitled to.

You have to put pressure on to get compensation. This endlos dead cars not working because they cannot locally store a few batteries to repair the cars, when needed is a joke.

Mine was in the shop for over 2 month. We started to push very hard and suddenly they found a new module in the country and things moved much faster...

 

[feye]

even though it's a pain in the ass - a new battery 3 years into the vehicle's ownership with a new chemistry isn't a horrible outcome - sympathies for the wait time for the repair.

They often say new battery, and at the end they still just swap a module...

The 2020 Taycan's have another battery chemistry than the later ones.

I am asking my question to understand: Do we mostly see 2020 taycan with battery failure because they are older. Or because there was something wrong with the 'old' chemistry.

Given the fact that they do not just replace the broken modules, but instead the whole pack (with the new chemistry), I am assuming there was something wrong with the old types of battery.

To confirm that hypothesis, I am asking if anybody knows of a full battery failure on a +2021 Taycan.

It was designed for that, right?

 

[daveo4EV]

either way "fresh" battery (whole or partial) after some number of years is not a bad outcome - other than the repair time.

I guess it depends how much you paid for your car and how old it is. If you lose 500 or 2500 per month makes a difference in that calculation. Condidering that a singe module is not much more than 1000 USD...

 

[feye]

Yes, but that design also has it's drawbacks, because it adds a lot of weight....

 

[Bughouse]

Just had the same problem with my 2020 Turbo (29k miles). Luckily my dealer had a Taycan 4S loaner. Car has been with them for 5 weeks and they just got back to me and said that they will be repairing the cells in the battery. I'm not sure how many cells need to be replaced out of the 396 in there. I wonder if this will be a stopgap on the way to a full battery replacement.
