What happens after 8 year battery warranty?

[sraworld]

The warranty for the battery is 8 years from Porsche. Nobody is out of warranty as of 2024. Has anyone established what happens in 2028 and beyond?
1 Can you extend it with Porsche?
2 How much cover is there in the warranty? It will be a succession of used car 2-year warranties.
3 Are there insurance companies who will insure an 8-year Taycan?

We have four years to investigate.

I have just opened the following bombshell answer to this question from the Porsche GB CEO support team, after emailing the Porsche GB CEO [email protected]

... Porsche has deemed that HV batteries are a wear and tear item and are excluded from the Porsche Approved Warranty (full stop).
The published warranty terms use the the term ‘normal wear and tear’. If the communication above is accurate, I think this position breaks precedent, and appears to be opposite to the UK Consumer Protection from Unfair Trading Regulations 2008.

Whilst the reply above says Porsche will offer support on a case by case basis, not having clear cut support for total failure of HV battery systems (and their related components) would make Porsche EV ownership (and E-Hybrids) a high risk gamble, with depreciation and resale consequences.

The images below have the earlier correspondence. I’m still contemplating next steps, others may also wish to review their plans.

1. Time will tell, only when Porsche is confident enough.
2. what? If extendible it will be exactly the same as the first 8 years. T
3. Of course, almost every 4+ year old ICE on the road is out of warranty. And they are all insured. What would be different? A battery lasting 8 years is a good one, so it will not break suddenly in year 9.

What are you afraid of?

Car will be a write-off in 8 years if the battery fails I think. Worrying about getting it fixed a bit of a waste of time.
That said, someone posted elsewhere that degradation has been much lower than expected, so hopefully won’t be an issue. Hopefully.

We all will reach the 100k km’s earlier than the 8 years so a lot of people already have a Taycan with a battery out of warranty. I did not read any bad story on this forum - filled with bad stories - about a battery after warranty that gone bad and wrote-off the vehicle. Lets not start a new forum thread filled with fears. Those fears and the discussions about them will depreciate our vehicles more than actual issues and age of batteries.

100k miles NOT kms/8 years.

I would be curious to know the cost of replacing an engine on a 992 for instance. The taycan’s battery is an expensive part of the car but batteries will go down in price IMHO and I would bet that the new 992 GTS’s engine with its hybrid technology will cost anyone a n arm and a leg to replace if it goes bust after the 4 year warranty expires.

My concern is how long will replacement batteries be available?

Let’s say your car last 10 years and you still love it buying a new battery may not be a bad idea for you and would still be cheaper than new 200k car.. but will they still offer replacements?

These cars are pretty iconic / classic looking. I don’t think they will age in looks or handling poorly.

Mmm, 50-70k on a new battery including labour is such a great deal… it’ll still remain an old car with big mileage. It’d be better to spend those money on cpo instead, which will be newer, with better tech, with less mileage.

In overall, that’s not going to work. It’ll be a waste, not a car… unless they really come up with a solution when changing a battery doesn’t cost you a fortune.

I bet there's a fair few people over 100k miles already.
Porsche have already mentioned some French bloke in excess of 300k km.

My bet (hopefully) is that in the coming years a large portion of the motor repair industry will pivot from repairing ICE cars to EV's and especially battery repair/replacement/re-condition/recycle
?

It needs to happen.
I would imagine it will be fairly lucrative for those that crack it.

The reality is that the battery IS a consumable and its life will, at least in part, be dependant on how it is treated by the owner, like the brake pads and discs, for example.
Based on Porsche's support of their older models I am hoping the battery packs can be overhauled, perhaps including new technology if the hardware is compatible and firmware can be altered to suit.
The labour to strip and rebuild the battery would not be negligible but probably by then specialists will be around who have sussed quick ways.
Just like rebuilding a flat 6 with improved parts.

Yes, there will be new models by then but people may still keep the older ones, like they do with 911s though they are nowadays a totally different type of car, in a different market sector to the original, but who knows.
As I have written here before there were predictors of doom for the Toyota Prius and its hybrid battery over short life and excessive replacement cost but we now know they can be rebuilt at modest cost and our first one, now 19 years old, is still working fine in daily use on its original battery.

The one thing I do not think is equivalent in IC car speak is mileage.
Mileage is a reasonable way of estimating wear and life on the mechanical parts but with something like a battery chemical deterioration is also part of it and that will be time and climate dependant.
So again, like any used car, its condition strongly dependant on its history.

No doubt at least as much.
The difference is that a 992 isn’t soon going to depreciate to less than the cost of a replacement HV battery.
2nd hand battery modules may become available but the resource to strip and repair a HV battery is very unlikely to exist outside franchised dealers for a long time. I see no reason for the cost of the labour and new parts to decrease.

If all Porsche EV cars become scrap metal after 8 years, just because Porsche refuses to repair batteries for a fair price on what’s supposed to be a 50k car (at least), Porsche will be in big trouble in 10 years from now with all its macans, boxster, Cayennes and taycans going to the scrap yard.

Non one will buy a second hand one - ever. What’s more, the second Hand Market will die, including the Porsche approuved business.

If manufacturers do not solve this, I don’t see any future for the EV market.

 

[Bognar67]

Absolutely!
Additionally if 2nd hand Taycan market collapses new car market collapses as well with short delay. Nobody will buy a (new) car that depreciates to zero after 8 years.
In my individual case I have already changed my 4-year car swap habit to 7 with my Taycan to make the depreciation pill sweeter with longer use. If the 2nd hand Taycan market will be crashed in 2029 and will not be able to sell the car on a kind of value, I will use it until it dies and never ever buy again an electric car.
Is it really the future of transition? ....
