2010 Porsche 911 GT3
The Problem: The high-performance Porsche 911 GT3, which produced 435 hp, as well as its 450-hp GT3 RS cousin, have unique center-lock wheels. The setup, originally created for racers who wanted to swap wheels more quickly, saves at least five pounds per wheel but requires owners to apply nearly 400 lb-ft of torque to the center nut. Porsche’s recommended maintenance intervals may not be sufficient to keep the system in good shape, and the 911 GT3′s rear wheel hubs could fail prematurely. That could be problematic in a sports car that can hit 194 mph.
The Fix: Porsche will replace the rear wheel hubs, and also will give owners an updated maintenance schedule designed to keep the hubs in working order for longer. The recall starts this month.
Number of Vehicles Potentially Affected: 455 Porsche 911 GT3 models built between May 2009 and February 2010. Given the limited appeal and high price of the cars, which kept sales volumes low, the recall covers just about all GT3s produced during that period.
