Porsche Cars North America recall ARB0 concerns all Taycan electric sedans produced from October 21, 2019 through June 13, 2024 for the United States market, including a number of facelifted 2025 models. All of these vehicles feature VINs beginning with W for what used to be West Germany, with Taycan production handled by a facility located right next to the assembly plant where 911s and 718s come to life.
Known as 24V-455 in the NHTSA's vernacular, said recall can trace its roots back to June 2023. That's when the automaker from Zuffenhausen started receiving field reports alleging brake fluid leakage incidents from cracked front hoses. Prior to filing the recall documentation with the National Highway Traffic Safety Administration, the company was aware of 7 resorts worldwide.
Optical analyses, CT analyses, bench tests (including burst pressure testing of the front brake hoses), and full braking tests didn't initially reveal the root cause, but did confirm something. In case of a service braking system failure, namely the front-axle brakes, the secondary system remains completely functional, therefore fulfilling the requirements of Federal Motor Vehicle Safety Standard 155 for brake systems.
Porsche ultimately determined that certain steering and driving conditions may stress the front brake hoses at the point of minimum bending radius, which damages the inner fabric layer of said hoses. The supplier of the front brake hoses is Valeo Powertrain Systems Driveline of Ebern, Germany. The automaker highlights that no accidents were reported in the United States, yet one non-US incident resulted in an accident.
In case of a leakage, drivers will be alerted with messages that include PSM failure and brake fluid low, with PSM standing for Porsche Stability Management as the driver. Obviously enough, PSM is Porsche's way of saying stability control.

Customers will be notified within 60 days of the submission of the recall documentation with the National Highway Traffic Safety Administration, the last day being August 16, 2024. No later than July 3, 2024, dealers nationwide will be instructed to replace said hoses with an improved design.
The improved part? That would be an increased bending radius. The redesigned hoses were introduced on May 13, 2024. Internally referred to as 9J1, the zero-emission Taycan is based on the J1 platform, which is derived from the MSB for internal combustion applications.
The J1 is shared with the Audi e-tron GT. Rather unsurprisingly, Audi has also facelifted the e-tron GT for model year 2025. The Porsche brand, however, produces the most powerful electric vehicle in the form of the Taycan Turbo GT. For two seconds, it develops a staggering 815 kW or 1,093 horsepower.
Said output is only accessible in cars equipped with the Weissach package, which enabled the Taycan Turbo GT to lap the Nurburgring a mere two seconds slower than the 1,888-hp Rimac Nevera. Not bad for a series-production EV that's way more affordable that the limited-run Nevera, innit?
After a 1:43 scale model of a Ferrari 250 GTO sparked Mircea's interest for cars when he was a kid, an early internship at Top Gear sealed his career path. He's most interested in muscle cars and American trucks, but he takes a passing interest in quirky kei cars as well. Full profile
