Some vehicles were equipped with center locking hub and wheel assemblies. Over time, the hubs can wear prematurely. As the hubs wear, the wheels could loosen, increasing the risk of a crash. Dealers will replace the central locking wheels and hubs with an improved design. Porsche has not yet provided an owner notification schedule. The Porsche recall number is AB01.
Adjusting the front seats to an extreme forward or rearward position could adversely affect the seatbelt locking mechanism and the seatbelt mount could detach from the anchoring system when the seat belt is fastened or opened. In the event of a crash, the seatbelt may not properly protect the seat occupant, increasing the risk of personal injury. Dealers will install an additional locking element on each front seatbelt anchoring system to address this concern.
On 2011 Boxsters with a convertible top, the locking hook at the front of the soft top should securely engage the top of the windshield frame when the soft top is closed. 9 Spyder models are being recalling because the soft top may not latch correctly to the windshield frame. As a result the soft top could open unexpectedly while driving at higher speeds, increasing the risk of a crash. Dealers will replace both the locking hook and lock catch with redesigned parts to correct this concern.
The front seat backs may not meet Porsche's strength standards. In the event of a crash, the seats could twist, tilting on one side to the rear. This could result in personal injury to the seat occupant. Dealers will replace the affected seats to correct this concern.
A power steering fluid leak may develop due to a loose fitting on the fluid pressure line. Fluid leakage can result in reduced steering and/or clutch assistance. If the leaking fluid were to contact hot exhaust components, it could ignite. Dealers will tighten the affected fittings to the proper specification. The Porsche recall number is A307.
