The 2010 Porsche 911 GT3 has 3 recalls, all centered on the same critical issue: the rear wheel hubs can fail and cause a wheel to separate from the car, resulting in loss of control or the detached wheel striking other vehicles or bystanders.
The rear hub failure risk is present both in everyday driving and under hard track use, and prior maintenance intervals recommended by the manufacturer were not sufficient to catch hub wear before it reached a dangerous point. A hub that cracks or breaks can allow the entire wheel and tire assembly to come off at speed, leaving the driver with no ability to steer or brake on that corner of the car. The separated wheel assembly can then travel independently and strike other vehicles, roadside property, or pedestrians nearby.
