I experienced 4 uncontrolled acceleration events with my leased 2007 jaguar xk coupe in the months prior to march 2009. the car was taken to dealer each time and "extensively tested". there was no answer ever given for the cause. the jaguar north america distributor consumer office was ineffective and unresponsive despite numerous contacts with them. i returned the car to bill knight ford/jaguar tulsa in march 2009 and leased a 2009 jaguar xk. *tr
