Complete brake failure !!

[Vercingetorix]

So seven cases in the USA. Seems Porsche is being very proactive.
Porsche first received reports of the front brake leakage issue in June 2023, per the NHTSA report. The automaker has seen seven cases of such leakages in the U.S., though none have resulted in accidents. One report outside the U.S. did include an accident, though there were no injuries, and featured a vehicle traveling significantly over the speed limit at approximately 120 km/hour.

I am dumbfounded at Porsche's lack of fundamental engineering integrity concerning the foundational aspects of this car. They couldn't develop a charging system that worked. I mean - seriously. The couldn't develop a reliable battery, and now they don't seem to be able to design a reliable braking system. Incredible. I don't support people apologizing for this kind of poor engineering. It only encourages more of the same.

Ack on demanding (and maintaining) high standards.

Nack on the binary assessment of engineering; you do the best you can, double-check your work and test the hell out of it. The inevitable mistakes will be flushed out and addressed. The fact that these occur does not mean the engineering was poor - though of course the frequency and gravity of failures does play a part in earning that qualifier.

If you read through the NHTSA report (or various articles), it's a "design and circumstances" problem, estimated to impact 5% of US cars (and 1% worldwide). They should have known and done better - particularly since they've been at the forefront of innovation in hydraulic brakes since 1930s - but this is hardly a case of "poor engineering".

porsche software I excuse - mechanical engineering is supposed to be their strength - honestly my 2020 Taycan had way more problems than _ANY_ of the 5-7 Tesla's I've owned…

I'm a bit surprised - and disappointed - learning of this defect, and I'm not trying to apologize for it on the forum. My reaction is more from the perspective of an engineer: there's a difference between "not giving a shittrying" and "making a mistake". I bristle when the latter is confused with the former when seen through the lens of hindsight.

I don’t think the man who started this thread found them too proactive. They just shrugged the shoulders and said oh well this is just a brake hose splitting with no sense of urgency or interest in digging into what actually happened.
If @Clive is still on the forum, would be interesting to know how it all ended

the car was repaired by porsche and i sold it that same week

porsche agreed the pipe had failed and hadn’t been damaged but didn’t seem worried about this, i was not charged for repair

i found out the car was involved in an accident 2 days after it was sold but have no idea what caused the accident etc

personally i find it extremely concerning that such a safety critical component can fail on a dealer serviced car at just 3 years old and that such a failure can leave a 2.5t car completely without brakes

Let me say that usually I find your comments/posts well balanced and insightful (to say the least...) but I am a touch concerned that Tesla is held up as a paragon of virtue in this context.

From what I have seen from Tesla makes me doubt that they would have acted as Porsche did in this context and within a relatively short timeframe with the small number of issues reported.

On the best selling Model Y "tens of thousands of Tesla owners who have experienced premature failures of suspension or steering parts" and these owners were blamed for the failure, even when the vehicle had only been driven a few hundred miles..." memos sent to technicians globally, instructing them to tell consumers that broken parts on their cars were not faulty."

Tesla blamed drivers for failures of parts it long knew were defective

So while yet another recall is not exactly what this Porsche model needed, it strikes me that the precautionary principle prevailed.

Thanks for updating us Clive, even though you have sold the car.

This post (and your original post) are the most important ones to me.

It reinforces my thinking that this is my first and will be my last Porsche.
I have had more issues with this car in 3 years than all my other cars combined in the last 42 years.

And the worst bit is, you are constantly expected to pay a premium for it.

Things can go wrong. But it's how people deal with it when they do that matters.

I could not have said this better.... It's a wonderful car to drive, but every time I get behind the wheel I expect something to fail - and although it is under warranty and everything, that is not the feeling I would like to endure. And I don't think the problems have anything to do with it being an EV. I have had an i3 since 2017, and in 7 years absolutely nothing broke in it, and it didn't have any rattles or noises this forum (and my car) is full of... I don't really understand how they keep straight faces when telling that all this is "normal" for a car they sold for £150k...

to be fair this was pretty much the first issue we had in 3 yrs /66k miles ………. but it’s a very serious one

the way the dealership and porsche gb dealt with it was not good in my opinion

I find your contribution most useful! One aspect that puzzles me a little is whether your case was included in the world-wide recall in the sense that it was reported further despite the local team being seemingly dismissive towards you after having repaired it. You reported this on here on May, 15th and the recall was announced in the US a little over a month later, on June, 19th, in effect recalling all 150,000 Taycans worldwide...so someone @ Porsche must have taken these incidents seriously rather than having attempted to brush these under the carpet.

If this was some other manufacturer, you might have to wait until there were 7 deaths before responding.

sorry , as i’ve sold the car i’m not up to speed on this recall ? what exactly is being done in this recall and does it include the hoses ?

I hope there’s a slightly less gruesome benchmark to aspire to

This looks like exactly your problem. The front brake hoses split when “driver sets them at the wrong time at the wrong angle”
