2021 Porsche Taycan: Brake booster defect may cause brake pedal failure

What this means for you

Our assessment, not the agency’s: severity 4/5 (Severe).

The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.

Our severity reasoning: This is a structural vehicle defect affecting the brake system, a critical safety component. The pressure input rod defect will directly cause brake pedal failure, creating an immediate risk of vehicle crashes. While no injuries have been reported, the nature of the defect—complete loss of braking capability—qualifies as a severe structural defect per the rubric.
