- 2023 Taycan CT 4S
@Clive you've said you're going to sell the car immediately it's fixed and will lose lots of money on it as a result. I'm sorry to say this, and I understand how scary the brake failure must have been for your wife, but I think this is a knee-jerk reaction that's not logical when you think about how the Taycan works.
Your friction brakes have failed. The burst pipe means the car was unable to apply enough pressure to grip the brake discs and slow the car to a stop. Yes, it's shocking that the friction brakes could have failed on a well-maintained 3 year old car, but this failure could happen to any car that uses flexible pipes to transmit brake fluid pressure. Unfortunately any component - even one as important as a brake pipe - can fail without warning despite passing QA checks during manufacture.
However... you said your wife was able to slow down normally to a very slow speed before the brakes failed. This is because the unique thing about the Taycan is that at speeds above walking pace (where brake failure could be very dangerous) it doesn't use the friction brakes at all*. It uses the electric motors to slow down - as others in this thread have pointed out.
Any car could suffer the failure that yours did. It's not a Taycan problem. Or a Porsche problem. It's a 'sh*t happens' problem. Someone in this thread said it happened to them twice!
Porsche could argue that the Taycan must be the safest car in the world at coping with a burst brake fluid hose, as the friction brakes are not used at higher speeds where loss of fluid pressure could be very dangerous!
If you're selling your car because you've lost confidence in the friction brakes then I'd urge you to step back and consider the logic in my argument.
Whether you can convince your wife to allow you to keep the car is another question...
* Assuming 'normal' pedal force in 'normal' driving conditions...
