Extended Warranty Options for HV Battery?

[tuptaycan4S]

I recently purchased an extended warranty for my ‘20 Taycan. Unlike ICE vehicles for which the extended warranty covers the car and the engine, (as I am sure you are all already aware), the Taycan extended warranty does not cover the HV battery. On questioning at the dealership, no answers were provided to me as to the possibility of extending the HV battery warranty. I was advised that they were unable to get clarity on this issue from Porsche head office. My assumption is that Porsche is reluctant to offer warranty options until significant real world reliability data has been collected. Regardless, if I am not able to extend the battery warranty, I will be forced to trade the car prior to the expiration of its original battery warranty, as replacement costs can be astronomical. Likely this would have a strongly negative impact on resale values as well. Does anyone have information regarding HV battery warranties?
As a side note, the HV battery is supposed to operate within certain capacity parameters to be considered healthy. 100% capacity at delivery, 80% net capacity within first 3 years and under 50k, 70% capacity within 8 years and under 130k.
I asked the dealership to tell me the current battery health (my iPhone does this with the click of a button) and they said they were unable to. Has anyone had experience with this?

? My car was recently in for service and they were able to provide me the battery SoH upon request.

Lots of posts and threads about battery health measurement on the forum. Use forum search or google search for "SoH".
Also see this thread https://www.taycanforum.com/forum/threads/baseline-for-hv-battery-soh-performance.12815/ , which among other things, discusses dealer SoH measurement.

I will address SoH with dealership again. Any info regarding warranties?

I think you're right when you say they are waiting for real world data to build...

Give it another few years and we may get more options.

Then again, they may just think they don't need to

I suspect the industry at large will also play a part. There's becoming less and less that separates EVs from different brands... If others offer longer warranties and/or extending options then Porsche may follow.

I can see that requiring clarity and options later on maybe but don't you have about 5 years left on the battery only warranty?

The HV battery warranty already goes to their maximum protection period. The extended warranty let's you sync up the expiration dates by extending the rest of the protection.

Interesting, so, say you add a year 4 warranty the battery gets 9 years then?

Battery warranty length currently doesn’t change despite additional car warranty.

This is true, however I suspect I will hit the mileage limit far sooner. I’m at 90,000km already.

You’re probably right. I suspect they would have a hard time touting their quality manufacturing if other lower level brands were outperforming them on battery warranty. Not to mention what would happen to resale values of all these cars with no battery warranty left. The values will tank and that would not look good for the brand.

And what about if you put in a complete new battery in after 8 years? Will you get a new warranty for another 8 years?

 

[ShiftyWolf]

Nope.

Maybe a 12 month "warranty", if you are similar to US dealer installed parts guarantees.

That is weird though. If the car is new, you get 8 years on the battery, if you replace the battery with a complete new original battery, you only get one year… so better just junk the car, strip it and sell it for parts and then buy a new car? ?

Porsche parts come with a 24 month warranty in the US. Don’t know if this applies to the battery or not.
