2003 Porsche 911 RecallsFront Seat Backs May Be Weak
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.
