PORSCHE is recalling some cars to replace the control consoles for the Traction Control Off and Porsche Active Suspension Management buttons. Worldwide, 128 units of the 911 GT3 and 911 GT3 RS built between Sept 28 and Nov 9 this year are affected. The faulty buttons may cause a malfunction of the traction control and damper settings. The affected cars are required to undergo an inspection in the workshop lasting about half an hour.
