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, leading to loss of control or the detached wheel striking other vehicles or bystanders.
All three recalls address rear wheel integrity. The hubs are prone to failure under certain driving conditions, including but not limited to aggressive or track use, and the original maintenance intervals may not be sufficient to catch hub wear before it becomes dangerous. A hub failure can cause the rear wheel to break away entirely, leaving the driver without control of that corner of the car.
