RELATED TO JAGUAR SERVICE ACTION PUBLICATION NUMBER 303-S514, "THROTTLE CLOSED POSITION OPERATION" THIS IS A KNOWN DEFECT FOR JAGUAR. IN THE JAGUAR SERVICE BULLETIN, JAGUAR STATES "UNDER EXCEPTIONAL CIRCUMSTANCES THIS CONCERN COULD CAUSE THE ENGINE TO CUT OUT... THE ENGINE SHOULD RESTART WITHOUT DIFFICULTY ONCE THE VEHICLE HAS COME TO A COMPLETE STANDSTILL." THERE HAVE BEEN NUMEROUS COMPLAINTS REPORTED AS A RESULT OF THIS "COMPLETE STANDSTILL" HAPPENING ON MAJOR MOTORWAYS WHERE THE FLOW OF TRAFFIC IS IN EXCESS OF 60MPH. MY 1998 JAGUAR XJ8L HAS HAD THE SERVICE ACTION PERFORMED, WHICH REPLACED THE ORIGINAL THROTTLE BODY ASSEMBLY WITH THE EXACT SAME THROTTLEBODY FROM THE SAME VENDOR. THE NEW PARTS USED FOR THE REPLACEMENT IS THE SAME ONE THAT FAILS, IT IS DEFECTIVE AND ONLY COMES WITH A ONE YEAR WARRANTY. THE CAR IS STALLING AGAIN, AND JAGUAR REFUSED TO PAY FOR THE REPAIR. ON MONDAY MORNING, MARCH 17, 2008 WHILE DRIVING TO WORK, MY CAR RECENTLY STALLED WHILE HEADING ON I-35N THROUGH AUSTIN TEXAS, AT WHICH TIME THE TRAFFIC VOLUME WAS HEAVY AND THE FLOW OF TRAFFIC WAS NEAR 70 MPH, AND I WAS FORCED TO MAKE AN EMERGENCY EXIT FOR A CONSTRUCTION BARRICADE. IN DOING THIS, ANOTHER VEHICLE TRAVELING BEHIND ME HAD TO VEER OUT OF THE WAY TO AVOID A REAR-END COLLISION, AND PUMMELED THROUGH THE ORANGE CONSTRUCTION BARRELS. I HAD TO ALSO PULL HARD INTO THE CONSTRUCTION BARRELS TO AVOID THE COLLISION, AND MY VEHICLE SUFFERED FRONT PANEL DAMAGE. BOTH OF OUR VEHICLES SUFFERED DAM
