... In addition, the battery is covered for 8 years from the original manufacturing date, or up to 100,000 miles, offering extended protection on one of the vehicle’s most important components. ...
Just confirming: the high-voltage battery warranty on U.S. Taycans begins when the car left the factory, not on the car's in-service date?

Extended warranties always have exclusions, no matter what the people buying them believe. It's an insurance product, on which the underwriting company must make profit, so they will always exclude things which break often, or have to increase premiums. Anyone who thinks they outsmarted the insurance company by buying their warranty is kidding themselves - either their actuaries know what they are doing, or they go bankrupt and coverage disappears anyways. Whenever an insurance product sounds too good to be true, it usually is.

Personally I believe in buying catastrophic insurance only, i.e. things which would significantly affect my finances if I had to pay for them out of pocket. For anything I can afford, I am self insured, therefore pocket the profit (tax free too) the insurance company would normally get.

You make a very fair point, and I actually agree with part of what you’re saying—extended protections are structured as insurance products, and they are absolutely priced and underwritten to account for risk and profitability.

Where I’d add a slightly different perspective is in how they function for individual ownership. While some items are excluded or considered wear-and-tear, the value of a service contract isn’t about “beating” the system—it’s about transferring the financial risk of unpredictable, high-cost failures.

Porsche vehicles are far more complex than they used to be, and when something does go wrong, repairs can quickly move into the thousands, even for a single component. For some owners, that risk is worth self-insuring, and for others, the predictability of coverage and controlled cost provides peace of mind and financial stability.

At the end of the day, it really comes down to your ownership style—whether you prefer to self-insure and set money aside for potential repairs, or shift that risk to a provider for a known cost.
Either approach can be the right decision depending on how you plan to keep and use the vehicle.

I’ve attached a screenshot showing where you can locate the start date for both warranty coverages on your build sheet. This can also be requested at any Porsche dealer with the VIN.

The warranty start date is set by the Sales department once the vehicle arrives and has been reported sold to PCNA. It is not based on when the vehicle leaves the factory, but rather when it is officially received, inspected, prepared and delivered.

Thank you for confirming that the HV traction battery warranty begins on the in-service date, not the manufacturing date. For my 2020 CPO, that distinction is significant. The car left Zuffenhausen in February 2020, but its in-service date is April 2021.

My purchase receipt, warranty book, and dealer confirmed auto and hi voltage battery warranty starts from delivery date. Are they mistaken?
Or did a change take place after 2021? I have read the warranty book carefully and it makes no mention of a manufacture date for battery warranty. I suspect this was an afterthought by Porsche. This will have a bearing on what additional warranty I might purchase.

No, that is somewhat correct, as mentioned above. The warranty start date is set by the Sales department once the vehicle arrives and has been reported sold to PCNA. I’ve also attached a screenshot to illustrate how both coverages are activated at the same time and run concurrently to a certain point.

Kelli confirmed above that it starts on delivery date.

My view is that non-OEM warranties should be marketed and legally sold as insurance NOT a warranty. These issues are handled as claims (which can be easily denied) and not as an entity (like an OEM) that warrants that the product is free of defects for a given duration and will stand behind it if it doesnt….as an OEM would. I would never buy this type of insurance and in my view only those that would struggle financially if they had an out of pocket expense should even consider it.

At 18,500 miles and 6 months past factory warranty the A/C quit cooling. I purchased the extended warranty sold by the Houston Porsche dealership to last through the remainder of the battery warranty. Basically a 4 year extension. to 50k miles.
1) Dealer says diagnosis requires a $400 service that warranty does not cover.
2) Now dealer says expansion valve is bad and warranty specifically excludes this part.
Interesting because the only reason I Purchased the warranty was the dealer recommendation that it covered everything expect batteries.
3) Total repair is estimated at $3,000.
Any one else have this problem? Suggestions?

Not giving legal advice here, but as someone who deals with insurers for a living, your first step is to seek clarity in writing. If I were you, I would ask for a written explanation of where/how "the warranty specifically excludes this part."

I personally have a hard time seeing an AC expansion value qualify as a typical "wear and tear" part. Exclusions are construed narrowly and against the insurer under the laws of most states (for good reason) and an AC expansion value is not the typical W&T item like those expressly addressed in the exclusion (hoses, wiper blades, oil, brake pads, etc.).

You should also follow the "how to file a claim" section of the agreement. The administrator is the final word on what is covered, not the dealer servicing the car.

Feel free to reach out to me with a PM and good luck.

HOUSTON we have a problem !
Sorry, had to make this one :cool:

More seriously, I'm fully aligned with @SergeyIndy : it's nonsense, extended warranty has to cover that, it's obviously a "defect", it's absolutely not "normal wear and tear" (like changing the AC fluid would we wear & tear after 3Y if you used it extensively like almost every day)

You should ask the service advisor to request for "goodwill" coverage. I know with BMWs, depending on how far past the expiry is, they'll cover a %, and given it's just 6 months, the goodwill could be significant to close to 100%. There's a formula that they use.

Thanks for all the input. Evidently I purchased a technology warranty. Does not cover mechanical items or batteries. I thought I purchased coverage except batteries. The dealer offered a refund and discount on the full extended warranty. Unfortunately I have a $4,000+ bill for an A/C repair.

Wow, I mean I’m glad you will have a refund and a discount but damn, they wouldn’t goodwill the repair? I would call PCNA and ask if they can help with the bill.
