Anything that can be done to preempt failure? Can water pump be removed and seals replaced or full water pump replaced? Surely must be cheaper than failure and associated vacuum line repairs

Water pump replacement. Failures have been reported <50k miles so it’s a guessing game when a preemptive replacement should be done.

Cooling system hardware on these cars is garbage.

Yes, but no dealer will perform pre-emptive part replacement paid under warranty.. It will be on your own dime..

Just another profitable Porsche set of defective design/parts that is and will be filling Porsche’s pockets for decades to come.

Maybe in preparation for needed increase profits at the cost of its owners, to prevent decreased profit from the huge future EV competition, or maybe both..

Bought a 2019 3 months ago from a porsche dealer.

Car had 25,xxx miles. I put about 2k miles on it. Sitting at 27xxx now. Just had the dreaded warning the other day. Tried to drive it to the house and in the process received the "Cooling pump faulty" message in the dash. I was scared 'sitless'.

Indy that works only on porsches want $5,500 to fix. No extended warranty bought. Havent even gone to a Porsche dealership to find out how much $$$ they want.

Im surprised these are not under the class action for VW, Audi.. etc when the parts are literally used in all of them interchangeably.

I wonder if the "new" pumps are any different than the ones we have in to make it worth the $ to fix.

Im cooked.

I’m sorry to hear that. I take it’s not a CPO either?
Based on a few reports < 30k miles, it seems like this is more time based than mile based.
I think I will try to unload my CPO when the 2+1 warranty runs out in about ~3yrs

I’m wondering how common this issue is and at what time or mileage it tends to occur. Perhaps a survey similar to the one done for the 958 transfer case issue might be in order. I’m sure it helped push Porsche toward an extended warranty. Also, it seems to me that Audi extended the warranty on their Q5 water pumps because of the same issue.

Yeap, this is another Porsche design flaw, part defect, that will be enriching Porsche coffers for decades to come..

Porsche is not a stupidly naive company when designing engines and parts so they knew this early failure parts will profit them dearly..

.i.e. defective battery that's suppose to last 8-10 years but fails in around 2 years with a custom design so that no third party companies can create replacement parts and Porsche charged for 5 years $2,000 for the battery and $1,000 for labor on a simple battery/registration process.

Of course, this water pump with the vacuum system interaction that can produce $10,000 repairs as soon as 27,000 miles, like in this case..

Not to mention all the electronics gremlins galore that if you don't have warranty, you will be out several 10's of thousands dollars..

It seems Porsche is setup to continue to deep profit from defective parts, repair, ridiculous simple service prices, etc.. for decades to come..

Definitely, not the old Porsche company that pushed for high-end improved technology..

And, Porsche current engine technology is mostly common, so it is not like they are at the edge of technology.

Second, EVs will blow away all ICE defect/problem prone engines, so Porsche needs 600+ mile range, or there will be no difference with other even common EV brands that cost a fraction of Porsche overpriced brand.

With the water pump and the LiFePo4 battery gate, it’s hard to believe as a first time Porsche owner that it’s at the top among Euro brands for reliability and consumer satisfaction for consumer reports / JD power

The best thing about Porsche reliability is that it is not Mercedes (non-) reliability.
