Problems with 2006 Jaguar X-TYPE SERVICE BRAKES, HYDRAULIC

With my brakes applied and slowing to a stop at the bottom of an interstate exit ramp, my car seemed to jerk and then suddenly accelerated as if it was trying to go into passing gear. i immediately pressed the brakes as hard as possible and shifted into neutral so i could stop and avoid hitting the car in front of me. while in neutral, the engine kept revving and the tachometer was in the red. i turned the engine off to keep from damaging it and put the car in park. after the car in front of me had gone, i started my car to see if the engine would run properly. it seemed to be okay, so i carefully drove to my home which was about three more miles. several weeks prior, i had a similar incident when i was parking at the grocery store, but i was in the process of turning off the engine. when i started the car to leave the grocery store, everything seemed to be okay and i didn't think any more of it. i found several other people on line that have experienced the same problem but none of them could prove it to their dealer and nothing was done about it. i guess it will take someone getting killed before anything gets done about this sudden acceleration problem with the 2006 jaguar x-type. this incident has upset me and i am afraid to drive this car, but i don't have another vehicle to drive. *tr

Tl* - the contact owns a 2006 jaguar x-type purchased on november 10, 2006 with 15 miles. the contact explained that early in december 2006 while driving the vehicle between 40 to 45 mph and before coming to a stop sign the vehicle failed to respond when the brakes were applied. the vehicle continued at the same speed. this caused the contact to move on to the emergency lane to avoid hitting another vehicle. the contact continued to apply the brake pedal while on the emergency lane until the vehicle stopped. the contact explained that mid december 2006, while driving at 30 mph on a country road, the brakes did not respond when applied. even after the brake was applied the vehicle went at the same speed and the cruise control stayed on. after pressing the brake pedal a few times the vehicle was able to stop. at no time was the cruise control ever activated. the third time a similar problem occurred was on 1/20/07. the contact took the vehicle to thomas cadillac and jaguar of hardford on 1/24/07,where an ids was installed, and the pedal switch was adjusted and checked. the contact stated that the cruise control became active on all three occasions and pumping the brake pedal did not disengage the cruise control to allow the vehicle to slow down or properly stop. the failure mileage was 1743 and the current mileage was 2100. on february 16,2007 the contact's vehicle was involved in a crash. the driver was not able to stop while driving at 30 mph and making a right turn, under sunny and dry driving conditions. *ak update 4/9 *tr
