I’m thinking about buying a 2020 Turbo or Turbo S. My question is about the battery. I understand the Porsche warranty runs to 2028 (correct?). So… as a practical matter, does this mean that in 2028 when the battery is no longer under warranty (and may be teetering on its last leg about to die) the car is practically worthless because nobody wants a car with an imminent $30k expense?

Thanks in advance for your insights, much appreciated.

 

there is no evidence the battery will turn in a pumpkin at warranty + 1 day - LiON batteries lose capacity (most of it in the first 2 years) but don't tend to conk over and die…I mean it's possible, but that's not the statistical trend.

the car will be worth less, but no more so any any other car that could have major drive train components needing replacement (engine, transmission, suspension, turbos replaced. etc…)

10+ year old model S's seem to be doing fine in terms of operating - these batteries have actually turned out to be quite durable but with slightly less total capacity vs. day 1 (10-15% total capacity loss is common for 6+ year old batteries) - so your 270 mile Taycan Turbo S is now 250 mile Taycan Turbo S

Thank you both for the helpful info!

Based on the read, I think I’ve convinced myself that a 2020 Taycan battery will still be in good shape in 2028 and beyond. However, there was one post where the poster described his experience with a Taycan battery as a nightmare, with the car in the shop for months and nothing but frustration from the dealer and PCNA. A bit scary. Although the same can be said for various issues with gas engines, I’m sure.

So, I’ll continue to ponder and investigate the longevity of the battery… any other experiences with the Taycan battery would be appreciated! Thanks

 

_IF_ you have to get a battery - inventory, shipping times have been long in some cases (90+ days) - I'm not sure what the situation will be like in 2028 or later - better or worse? And also we have incomplete data as to if _EVERYONE_ has this problem with getting a new battery or just the people who complain have this problem…

the good news here is while it does happen that there are bad batteries that Porsche is replacing - it does not seem to be a wave or problems but rather low single digit percentages as one would expect for high quality components…

for the most part I think we can assume battery failure requiring replacement is likely to occur at at the same level of failure as any major engine component (ICE or otherwise) and given the seriousness of these types of failure replacement can sometimes be a lengthy process - but again nothing out of line with similar types of repairs for similar aged equipment - also Porsche's battery is very modular and many "repairs" that we do know about are simply replacing cells or modules that have failed rather than the entire battery - Porsche has designed the battery with this in mind so costs could be considerably lower if you're replacing a failed module vs. an entire battery…

none of this guarantees anything and any purchase could end up being "the statistic" - but that's true of anything ICE or otherwise and thats why cars in and our of warranty have different value propositions…

but EV batteries are not like 12V stater batteries in both cost and longevity and are expected to last/function beyond the warranty - failure is uncommon (but possible) with the major characteristics being gradual decline in overall capacity but yet remain functional as long as the total capacity is still useful in terms of daily driving habits.

 

I think in 2028 the car will be worthless.

Not because of battery degradation (or lack of warranty), but because it is a decade old EV architecture that will be outdated, at best, and obsolete, at worst.

 

2020 Turbo S are selling for $100k today… so you think they’ll be worthless in 4 years? If yes, that would be a far greater depreciation curve then their gasoline counterparts (eg Panamara, Cayenne etc) and a good reason to stay away from a pre-owned EV. That’s what I’m trying to figure out… is buying a pre-owned EV a bad idea? Thanks for your comments!

 

Hyperbole aside, I think there's a good chance that in 2028, a 2020 Taycan will be worth more parted out than selling the car as-is.

 

100K? You must mean asking price because I know of two local guys who just bought them under 90 K.
Dealers aren’t offering much on trades. IT’s a ton of car at current used pricing. I wouldn’t be that concerned about the battery there are some 2013/14 Tesla MS running around with 175K plus miles and battery is still over 90%.

 

The difference is EV technology is advancing rapidly and affects used EV cars more than gasoline counterparts (where technology is mostly established). Case in point, the 2024 Cayenne is a refreshed version of 2019 - 2023 models. I have a 2021 MY and drove a 2024. It has some styling differences and some engine changes, but otherwise not much different than the Cayenne I'm driving. But the 2025 Taycan has improved electric motors and more importantly (to many) considerably more range. That technology advance has affected the used car prices for Taycan much more than Cayenne. In fact, in Canada, Porsche is paying the luxury tax on leftover 2023 Taycans (up to $10,000 I think) and offering low interest rates for leases/financing. Can you imagine what range and features will look like on Taycan in another 5 years when there is a generational change?

 

I wouldn't worry about it. Just buy it and enjoy. I wouldn't pay anywhere near $100k though for a 2020 Turbo. There are CPO cars with 25-32k miles listed in the mid to upper 70's (probably have some wiggle room too) and extremely low mileage CPO cars in the low 80's. Turbo S cars look to be listed at mostly low-mid 90's. A few in the upper 80s (one low mileage with a $22.5k discount today on cars.com) and a handful sitting forever in the 100's+.

I would bet in 5-7 years that they'll be stupid cheap because people don't want to have the potential for a brick that costs 30-40k to replace batteries on. But the battery won't die just outside of warranty most likely. You just have to know you're on the hook if it does then.

But for now, I'd buy one and enjoy the heck out of it. EVs are good at what they do best really... drive around town and charge at home. Long distances would be a PITA but most of us run miles around home/work/school/kids sports/family events well within range and that covers 95-99% of driving.

 

Don't think I've seen any cpo cars under 50k miles for 70's. It seems the CPO cars are high 80's and low 90's. It makes sense that non CPO just took a big price hit due to the warranty running out. Fantastic car but would never own one out of warranty.

 

Yeah we're both in the same boat wanting one that has warranty. Apparently 10 of them on Cars.com with approx 32k miles or less and under 80k. There's a few that say they have factory warranty left for several months (personally would rather have CPO to buy more time).

Here's one CPO at 32k miles: https://www.cars.com/vehicledetail/8...-4efea87c5214/

 

This graph for the price trend on that Turbo S is quite telling.

 

I'd rather have a Turbo S for $75k vs. a Plaid … these are great cars and super quick - awesome daily driver's…
