Should I buy an extended warranty at point of sale.

[Jonathan S.]

that’s Porsche‘s plan. I got it directly from the selling dealership.

The Porsche-branded vehicle service plan that is purchased via a Porsche dealership yet actually not a Porsche extended warranty, or an extension of the actual Porsche warranty?

Correct, it’s called the Porsche VSP, an extended warranty managed by Porsche and underwritten by safeguard. True CPO can only be purchased at the point of sale. It has unlimited mileage no deductible. The VSP, depending on what level you purchase, may have 100,000 mile cap and small deductibles. In reality, they are both extensions of your warranty, but there is a reason why one is called CPO and the other is called VSP. You can Google it. It’s also on the Porsche website which explains the different of VSP plans and clearly states CPO can only be purchased at point of sale .

OK without doing too much digging, I think you confirmed it. These options l that I displayed must be attached at the point of sale. And yes, zero deductible and unlimited mileage so if I focus on those two points alone, I think I’ll take it.

 

[CoolDadLo]

Let me tell you my experience. I got a CPO 2024 4S in Dec 2025, with 8k miles and warranty coverage until 2030. I plan to extend my CPO for 2 more years until 2032 to match the battery warranty, and I’m hoping by then there is a warranty that covers it post 8y/100k miles.

Same mindset as me. I’m positive there be companies to warranty the 8 yr/ 100k mile batteries

 

[CoolDadLo]

Here it is guys . At time of purchase for any new or CPO Porsche at time of sale. Side note is that it’s 100% refundable if never used.

I thought it was sacrilegious to not have an extended warranty.

People selling you the warranty are professionals making money (quite a bit of money given how hard they push to sell a warranty at closing). They're making that money from you. The only way you come out ahead is if the vehicle somehow requires very costly repairs that the warranty company agrees to pay for. If you only own one car and have very limited financial means then perhaps that's a deal worth taking. If you own several cars and have some savings it would be likely less costly to just pay for any repairs yourself, over your lifetime of owning cars.

 

[Jonathan S.]

@tycanmt In general I agree with you, and I have never taken out any sort of aftermarket maintenance plan, or warranty, or insurance on any sort of product -- just car insurance, home insurance, and income-replacement insurance for the benefit of my survivors (i.e., so-called lift insurance). Instead I just implicitly self-insurance against such risks. (I've been particularly baffled by wheel & tire plans.) But I made an exception for the Taycan given the non-negligible chance of a high four-figure bill, even a low five-figure bill. Plus the rates were significantly lower when I bought my Safe-Guard vehicle service plan.

@CoolDadLo So it's just the usual Safe-Guard vehicle service plan, not an extension of the Porsche warranty. The only advantage of buying it at purchase is the option for unlimited miles. By contrast, mine runs out at 100k, but that is also when the federal HV warranty ends. So although your Safe-Guard vehicle service plan can have unlimited miles if purchased now, it will have limited coverage.

 

[CoolDadLo]

Yea the advantage is the unlimited mileage. And for me that’s where I think I’ll need it with the Taycan. I’ve never purchased one with my other cars. The good thing is that I can roll it into the loan as an option of just buy. Damn near cheaper than full PPF. So it’s a go for me. Best case scenario is I never use it and get reimbursed anyway. I’d probably not consider it as much if I was doing low miles. But I can’t be warranty - less after blowing past the 50k! My insurance covers all glass( even roof) and tire rack has roadside coverage for any tires if needed

I didn’t see it or I missed it but does the unlimited mileage cover battery or are you still beholden to the 100k mile warranty?

Safe-Guard excludes HV battery and some related components.

it’s a little more unique because it’s EV

"it should be able to do
300,000–400,000 miles
on its original battery"​

FWIW, the maintenance lead at Redwood City Porsche here in Palo Alto, CA dissuaded me from buying an extended maintenance plan when my four years of maintenance expired.

Like you, @CoolDadLo, I purchased the car intending to drive it for a long time --> which is why I inquired about extended maintenance.

The answer surprised me: "Even the cars that come in with super high mileage need almost no maintenance beyond wear parts (blades, brake fluid, and filters). There just isn't any maintenance to do on these EVs."

If you are getting the ceramic brakes, you'll never need brake maintenance beyond annual flush and fill.

Warranty is different than maintenance, of course.

So I asked Claude to do some analysis about the battery (assuming the electric drive motors are going to be a non-issue).

This is the prompt:

What is the anticipated life of the Porsche Taycan high-voltage battery? How many miles should one expect to drive on the original equipment battery. Assume a high-capacity battery.

This is the response:
Here's a comprehensive breakdown of what to expect from the Taycan Turbo's Performance Battery Plus pack:


Porsche Taycan HV Battery: Anticipated Lifespan
Official Warranty (Minimum Commitment)

Every new Taycan in the U.S. gets a separate 8-year / 100,000-mile high-voltage battery warranty. Porsche expects the majority of vehicles to retain 70% of the battery's original capacity through the first 8 years or 100,000 miles of normal use, acknowledging that the rate of reduction varies depending on individual usage and operating environment.

Importantly, the battery coverage clock starts on the original in-service date — the day the Taycan was first delivered to a retail buyer — and continues even after the basic 4-year bumper-to-bumper warranty expires, as long as the mileage cap hasn't been exceeded.


Porsche's Engineering Design Target

This is the more interesting number. At Porsche, the lifespan and reliability of its high-voltage systems are engineered to match those of combustion engines: at least 15 years or 300,000 kilometres (~186,000 miles).

Porsche conducted stress tests in 50% of all charging cycles, at temperatures up to 100°C (212°F), at simulated distances up to 300,000 km (186,000 miles) — even though its customers only fast-charge about 15% of the time.


Real-World Mileage Expectation

Most signs point to a Porsche Taycan battery lasting 15 years or more in typical use, with many owners likely seeing 200,000+ miles before range loss becomes a major concern, assuming the car is charged and stored sensibly.

With the Porsche Taycan's advertised range, it should be able to do 300,000–400,000 miles on its original battery over ~1,500 charge cycles, assuming reasonable care. That upper figure, however, reflects an optimistic best case and likely exceeds what most owners will see in practice.

A practical planning range for the Performance Battery Plus (93.4 kWh on your Turbo, 105 kWh on the 2025 refresh):

Scenario	Expected Miles
Warranty floor (Porsche guarantee)	100,000 mi
Porsche engineering design target	~186,000 mi
Conservative real-world estimate	150,000–200,000 mi
Optimistic / best-case	250,000–300,000+ mi

Degradation Pattern

The pattern emerging from early 2020–2021 Taycan owner reports is "boring in the best possible way": mild initial capacity loss in the first 1–2 years, followed by a slower decline — the classic "early drop then flattening" curve consistent with other modern EVs. There is no evidence of systemic, rapid battery degradation unique to the Taycan.

Most owners who charge to a moderate level (around 80–85%) and keep the car in a garage see modest, predictable degradation.


Key Factors Under Your Control

Key parameters influencing battery aging include temperature, charge state, and charging current. Optimal conditions are temperatures below 30°C (86°F) and a charge level below 90% when the car is parked for longer periods.

Given your Palo Alto garage situation, you're already operating in near-ideal conditions — cool, covered storage and presumably home Level 2 charging rather than daily DC fast charging. That puts your Turbo solidly in the higher end of the longevity range.

 

[CoolDadLo]

I didn’t see it or I missed it but does the unlimited mileage cover battery or are you still beholden to the 100k mile warranty?

No the battery is something separate. My hopes are that any unforeseen craziness will be covered with insurance. I spoke to progressive at length and they cover the battery issues under comprehensive. Besides that I have faith in new battery tech or I’ll use a 3rd party.

All this is great news. I wouldn’t be getting the extended plans for the batteries sake. I have optimism that it’ll last as long as stated from above. What I’m morseo worried about are the other electronic components. Not the wear and tear items…simply to minimize some of the Gen 1 concerns even though most are ironed out. If everything is based on “so long as the mileage threshold isn’t hit” I have to maximize that factor. An extra 4 or so can’t hurt. I don’t think I’ll ever say “well that was a waste.” I’d say… well that was a good call. Once the money is spent on it I’m not looking backwards!

 

[PorscheTaycan]

Personally for a car like the Taycan, I got extended warranty for the peace of mind.

 

[Flying ace]

just understand that you can buy an extended warranty anytime AFTER the sale too. And you're not obligated to buy it from your dealership. You can actually shop around the quotes and some dealerships will compete on price.
