2005 JAGUAR XJ SEDAN Engine And Engine Cooling Problems

DRIVING ON THE HIGHWAY GOING ABOUT 70MPH, NOT ACCELERATING NOR COASTING, JUST MAINTAINING SPEED. THE ENGINE BASICALLY SHUT DOWN, AND I HAD TO PULL ONTO THE SHOULDER, IT WAS VERY DANGEROUS AND FRANKLY, IT SCARED ME. ENGINE LIGHT ON, AS WELL AS "ENGINE SYSTEMS FAULT, PARKBRAKE FAULT, DSC NOT AVAILABLE" SHOWING UP ON THE DASH. I RESTARTED THE CAR ABOUT 4-5 TIMES AND IT EVENTUALLY STARTED. I AM ASSUMING, THIS HAS HAPPENED NUMEROUS TIMES OVER THE PAST SEVERAL YEARS AND NO-ONE SEEMS TO HAVE ANY IDEA WHAT IS CAUSING IT. IT HAPPENS ON BUSY HIGHWAYS AND LOCAL STREET DRIVING. THIS IS A VERY DANGEROUS SITUATION. THE CARS ENGINE COULD CUT OUT AT A MOMENTS NOTICE AND LEAVE YOU IN A VERY DANGEROUS SITUATION! *TR

JAGUAR 2005 XJ VDP HAS EXPERIENCED MANY EPISODES OF UNINTENDED ACCELERATION DURING BRAKING TO A STOP. AS BRAKE IS APPLIED, THE ENGINE THROTTLES UP AND CAR CANNOT BE COMPLETELY STOPPED. WHEN CAR IS QUICKLY SHIFTED TO NEUTRAL AND BRAKING MAINTAINED, THE ENGINE REVS OVER 10,000 RPM AND THE IGNITION MUST BE CUT IN ORDER TO STOP THE EPISODE. ON ONE OCCASION THE CAR COULD NOT BE STOPPED AT A BUSY INTERSECTION, FORCING AN URGENT LANE CHANGE AND RIGHT HAND TURN TO AVOID ACCIDENT. JAGUAR HAS "REPROGRAMMED COMPUTER" ON CAR WITH A REDUCTION IN FREQUENCY OF THE EPISODES FOR ABOUT 6 MONTHS, HOWEVER PROBLEM NOW OCCURS SEVERAL TIMES/MONTH. *TR

I HAVE EYE ALLERGIES AND IRRITATION WHICH ARE AGGRAVATED BY VOC EMISSIONS INSIDE THE CAR. I AM TRYING TO FIND PUBLISHED INFO ON THE VOC'S IN MY 2005 JAGUAR XJ8. JAGUAR WILL NOT GIVE ME THIS DATA. PLS ADVISE WHERE I CAN FIND IT. I KNOW THAT DOT HAS COMPLIANCE STDS SO IT MUST BE PUBLISHED SOMEWHERE??? *NM
