What's wrong?
The affected part is a hexagonal flange nut, M12x1.5, used on threaded connections in the front and rear suspension of 2021 Porsche Taycan, Cayman, Boxster, 911, and 718 Spyder vehicles. These nuts clamp suspension parts together so the wheels stay located where the suspension geometry expects them under braking, cornering, and bumps.
On affected vehicles, the locknut thread was not cut deeply enough for a period in production. That extra friction caused the automated tightening tool to stop early, before the connection reached the intended clamp load. A connection that starts under-tightened can loosen with driving, letting the suspension component move instead of staying fixed in its designed position.
There is no assured warning sign before failure. Owners can hear abnormal noise from the suspension area if a component begins moving at the connection, including over bumps or during turns.
