The typical porsche Warranty is 4 years or 50K miles which ever is hit first. The CPO adds on 2 years unlimited miles

So lets say that you are interested in a car that is 2 years old but has 40K miles. You intend to drive 10K/year

Which of two apply
Scenario one: You are covered on the original warranty until it hits 50K (about a year) and then two years for the CPO unlimited miles. So based on your driving a total of three years
Scenario 2: the unlimited miles kicks in immediately and it is covered for the remaining two years and then an additional two years and how much you drive never comes into it.

If scenario one, how does Porsche know when you hit the 50K to cut off the old warranty and begin the CPO.

as far as i know, the CPO is the same as the original warranty. there's nothing to get cut off. it just gets a revised expiration date. that's what i was told.

I think that’s correct. I’m pretty sure it’s the best CPO warranty out there and really shows that Porsche stands by its products and further differentiates themselves from other brands. This was a key reason I went with a Macan vs an Audi SQ5. It’s also why I switched from BMW since they have cut their CPO warranty, making it much less attractive on top of their reliability issues.

As soon as you come in for warranty work Porsche will see your odometer and verify your in service date so the appropriate warranty will apply.

I just purchased a 2019 CPO. The CPO warranty is same coverage as original warranty. Whatever the date the car was originally put in service starts the 6 years with unlimited mileage. So really no worry of stopping original warranty and beginning CPO.
That’s my understanding.

Scenario 1 is how the verbiage of the CPO warranty is written. As for how Porsche will know when you cross the 50k mile mark, that I am not sure but I would just go by the assumption that they will know somehow

If you bring your vehicle in for service and it is over the new car warranty (NCW) mileage limit (in Canada it's 80,000km) the CPO clock starts at that service visit - i.e. you don't get an extra year if you hit 80,000km 3 years into the 4 year NCW. If you don't use up your mileage in NCW at the 4 year mark, then the CPO starts at midnight on the day your NCW expired. They know because Porsche tracks your mileage every time you visit them, whether it's manually recorded, by a key read on newer models, or by a vehicle scan (which they are required to do for just about anything)

Does the car or key keep a timestamped log of mileage? If not, what stops an owner of a CPO car whose NCW has expired based on mileage prior to the 48th month, from using indie shops to avoid having a dealer record the over-limit mileage and "starting the CPO clock"?

Let’s think about it for a minute - does it matter if Porsche knows the second you click over 50k miles before the 48th month? No, it doesn’t. Why? Because unless you actually need warranty service it’s irrelevant.

Say you hit 55k miles in month 42 and your car is running like a champ. Does Porsche care? Not at all. Then let’s say a month later you have an issue at 56k miles and month 43. You bring your car to the dealership and they inform you that your new car warranty is up. Doesn’t matter that it technically expired a while back since you were not trying to make a warranty claim.

I'm not sure I follow your example, so let's try mine. I buy an 18 month-old CPO car with 40Kmiles. One year later, at the 30 month mark, it turns over 50Kmiles and the NCW expires unbeknownst to Porsche because I don't bring the car to them. If I/we understand correctly, that's when the CPO warranty starts and lasts for 24 more months out to month 54. I use an indie for all service and non-covered repairs. Month 60 rolls around and the transmission fails. The CPO warranty expired at month 54, but does Porsche have a way to know? Last they saw the car it had the balance of the NCW plus CPO which together could've taken it to month 72. Only knowing when it crossed 50Kmiles could they know exactly when CPO started. So I'm back to my question above, does the car or key keep a timestamped log of mileage?

I see what you are saying now. I guess we are back to square one which is not knowing what the mechanism is (or if there is one) for Porsche to know when you tick over the 50k mile mark.

As far as I know there is no backend mechanism for Porsche to know when it ticked over the mileage unless you bring it in to a Porsche dealership. So in the indie shop example you are correct in that Porsche would not know unless you brought it in to them.

However, the only thing I can think of is that VAL's (Vehicle Analysis Log) store fairly detailed information regarding both active and passive faults, so if there are faults during the "grey" time period that aren't cleared prior to your dealer visit, they could see that, and possibly (though unlikely) retroactively backdate the warranty. This seems fairly far fetched to me though... but who knows. Technically it is a way for them to know!

Porsche logs every instance you come close to revving at the red line or over and you think that they will not have a query when it passes mileage or time markers for warranty?

I have no doubt the computer logs all manner of major and minor events, but the question is are the events timestamped. If they are, and therefore date and time are stored in the computer's memory, why must I reset the date and time in the PCM when battery power is lost? That's what makes me question the existence of timestamps in the log. Except for the warranty issue, the date is less important than the mileage when something occurs, so it may be there's a mileage stamp, but not a timestamp. I certainly can't say.

 

[DriveInHouston]

As far as I know, from the reports on overrevs, the time is kept from a certain specific moment onward.

I am not sure how the time zero is specified, or whether it is just cumulative hours of engine operation (i.e. 0:00 + 132h 51m 06s - level 4 overrev). This can give you the time in an indirect fashion, i.e. 7323 hr 34 m 26 s logged in maintenance (a physical time they can confirm), 7470 hr 02m 5s passed the 50k mi. mark.

Or something a lot simpler, as in getting a time signal via the embedded SIM card (which Porsche can access regardless whether you have pay for it or not).

Were I a betting man, I would not bet that there is no record of your crossing the 50k mi. mark that Porsche can retrieve.

I haven't asked Porsche for an explanation on the CPO, but 20 years ago, when I got a BMW 740 iL under CPO, BMW told me CPO meant 6 years or 100k mi. and not the sophistry of 'if you hit the 50k mi. early, you don't get 6yr warranty'.

Has anyone got a direct answer from Porsche saying this?

 

[gatorfast]

Maybe since most Porsche owners are so concerned with keeping low mileage they have never actually had anyone hit 50k miles in less than 4 years 🤣
