Porsche Brake Recalls Cover Leaking Hoses and Pedal Failure
Taycan appears most often in these Porsche hydraulic brake notices, with separate problems involving the brake booster, brake wear display and front hoses. AMB9 covers certain 2020-2021 Taycan and 911 Carrera vehicles: a loose brake booster pressure input rod connection could detach and cause brake pedal failure. APA5 concerns an incorrectly colored brake pad wear warning in certain 2020-2022 Taycans. ARB0 covers certain 2020-2025 Taycans whose front brake hoses can crack and leak fluid, reducing braking performance and extending stopping distance. The Panamera notice, AJ11, concerns front axle brake line corrosion in specified 2018 hybrid variants, with possible effects on front braking performance.
Warning signs to watch for
- APA5: The instrument cluster displays an incorrectly colored warning indicator for worn brake pads.
