What Happens To Us After 8 Years? (When battery warranty expires)

[GREATST]

The cells are CATL which is probably the gold standard. CATL has 40%+ gloabl market share and I can't recall a major issue with their cells. LG had issues with Chevy & Porsche. Sunwoda with Volvo/Zeekr. SK with VW.

Panasonic?

That's excellent news, imagine the utopia : J1.1 Taycan retrofitted +50% autonomy, problem solved

Thats exactly what we are aiming for in X years! Turn this one into a classic with new battery every so many years!

I unfortunately think the cars will take a huge nose dive in price after the 8 year battery warranty is up. These will be 20k cars no question at the 10 year mark. Unfortunately the battery isn’t the only problem. Until we get Indy shops Porsche is only going to hurt the used values as you are stuck with dealer pricing. Everything on taycan is ridiculously expensive to repair and are quite common. Among these are High voltage onboard chargers 5-7k, & inverters 20-30k. Had two separate taycans both riddled with problems. First one had 5 high voltage chargers replaced and both inverters. Second one had one high voltage charger and the rear inverter. This is just a small amount of things that were repaired on these cars. Until repair prices come down prices will continue to tank.

Even with all my problems I still loved the car it’s just a shame it’s gotten to this.

Interstingly enough the cost is not that bad following the calculation i made prior to purchasing my car.
we were in the market for new EV cars. Ended up with this 2022 Taycan.

Calculating from there, there really isnt a diffence between a new Lexus RZ and a 4-year old taycan 4s. And just a small difference with f/i the Toyota CHR+.
considered price, depreciation, insurance, roadtaxes, electricityconsumption, regular maintenance. Did not calculate any unregular maintenance since it’s unplannable.

of course this car is not new and i calculated it for 11 years versus 15 years of ownership on a new car.
In general I consider us lucky thst we can buy extended warranty for 15 years (exept battery) and hope - as with any car I owned - that she will run smooth for a long long time.

I'd be less worried about replacing the battery, and more about our cars no longer being able to connect to Porsche connected services.

Even though I am quite sure most batteries will hold well, these can anyway be replaced if needed.

But connectivity is a whole different animal. Two limiting factors there:

• On one hand, our cars rely completely on whatever horizon Porsche has decided on to support connected services for our cars.
• On the other hand, 4G/LTE will not be there forever. Early BMW i3 with 3G connectivity are no longer connected in many parts of the world due to 3G being phased out there. Same will eventually occur with 4G.

Some might not care about it, but I personally think that losing connected services will be a blow to the user experience of the car.

losing connected services will be a blow to the user experience of the car.

I'm quite sure there will be hackers who can work around this. Just like how we keep vintage cars alive today, in future, these 1st gen EVs will be "vintage" cars and there will be enthusiasts and aftermarket providers who will also maintain these.

Our J1.1 batteries are under a fire/safety recall that required that we all have special battery monitoring software. If that software detects a failing module it limits the car to 80% SOC and directs the owner to visit the workshop. What do we think happens when that message pops up after the 8-year warranty expires? Does Porsche honor the recall and fix the battery?

No, the repair is not at Porsche's cost after the HV battery warranty expires. https://www.taycanforum.com/forum/t...ll-modulex-ageing-detected-may-27-2026.35831/

Thank you. It does seem to imply that if an owner declines to pay for the repair after year 8, they are limited to 80% SOC and any resulting fires are on them and may not even be covered by insurance. Some states may have latent defect laws that affect this?

After 180 days charging capacity limited to 50% if not repaired.

And the related fault error is "cell module nn, ageing detected", so to Porsche it is HV battery aging, not 'latent defect'.

@Tooney I could be wrong but I don't think these words mean what you think.
When Porsche replaced 3 modules in mine recently they did mention this precise process. Except they don't invoice to *you*, they invoice to your PA warranty, which is actually an insurance company. I got the detailed Reparation order once the insurance (PA warranty) had paid my Porsche Center.

Anyhow, as I wrote in another post, being in a family of French lawyers (i'm the only Management/Sales guy but I did learn lol), I don't believe 1 minute that Porsche would try to withdraw from their responsibility * in case of defect *.

To make it simple :
*normal wear & tear* which is not covered by Porsche or PA means a slow degradation of the battery to whatever %, without disrupting the ability of the car to function normally (albeit reduced range).
If your car stops & tells you to park on the highway because the electrical system is down, then this is a clear *defect*, since it completely prevents your vehicle to perform it's most basic function, ie working and drive you somewhere.
Porsche cannot withdraw from that, and the PA insurance will pay defective modules replacement for example.
If ever they tried, you can count on the US to build a class action, which Porsche will loose, they're not stupid.

It works exactly the same as the original 8Y warranty, except in that case it's Porsche paying directly : it is written that the warranty is about 8Y, or 160000km, but only if the threshold of efficiency goes below 70% => which is exactly the principle of wear and tear.
Which is why they changed under warranty *defective* batteries (or just modules depending on their good will & technical issue identified).

Anyhow, just my 2cents

@Gkwan My reply was to question asked by US owner, and it was intended to deal with situation in US after original manufacturer warranty had expired. The TSB posted was issued in the US. The Porsche-branded EV vehicle service plan (so-called 'extended warranty') sold in US specifically excludes any repair of HV battery.

I am aware that the terms of "Porsche Approved" plans differ from the US plan. I have no opinion as to how Porsche Approved plans will treat HV battery problems, no matter what their cause.
