Porsche has found faults in a few switches controlling the traction control and electronic suspension adjustment systems in 128 of their 911 GT3 and 911 GT3 RS vehicles. The faulty switches can lead to the loss of traction control and the inability of the suspension to adjust with speed or mode selection. Models produced in 2007 between the dates of September 28th and November 9th are being recalled in order to implement the necessary repairs.
