2014 Jaguar XF Engine Problems

IN OCTOBER 2014, I PURCHASED A JAGUAR XF MODEL, THE CAR WAS USED AS AN EXECUTIVE DEMO FOR THREE MONTHS PRIOR TO MY PURCHASE. OVER THE YEARS, I HAVE SERVICED THE VEHICLE AT THE DEALERSHIP ONLY, THE CAR HAS EXCELLENT SERVICE RECORDS, AND HAS NEVER BEEN SERVICED ANYWHERE ELSE. ON 01/02/2020, THE 96,000 MILES SERVICE APPOINTMENT WAS DONE ON THE VEHICLE. ON MONDAY, JANUARY 27,2020, I WAS DRIVING HOME FROM WORK AND I HEARD A KNOCKING SOUND, I PULL OVER TO GET OFF THE HIGHWAY EXIT AND THE CAR LOSES ALL POWER. THE CAR HAD TO BE TOWED TO THE DEALERSHIP. SEVERAL DAYS LATER THE DEALERSHIP INFORMED ME THAT THE CAR'S ENGINE WAS COMPLETELY LOCKED UP AND THAT IT WOULD BE $20,000 TO FIX THE CAR, THE DEALER OFFERED DISCOUNTS AND I RECEIVED A CREDIT FROM JAGUAR CORPORATE, WHICH BOUGHT THE SERVICE PRICE DOWN TO $7,000. THE DEALERSHIP BELIEVES THAT SOMETHING BROKE APART IN THE ENGINE, CAUSING IT TO LOCK UP. BUT I AM REFUSING TO PAY THE $7,000, MY CAR HAS EXCELLENT SERVICE RECORDS AND HAS NEVER BEEN SERVICED ANYWHERE ELSE BUT THE DEALERSHIP. I JUST HAD THE 96,000 MILE SERVICE PERFORMED ON MY CAR AND EVERYTHING ON MY CAR WAS WORKING IN PERFECT CONDITION. THIS SERVICE ALSO INCLUDED AN OIL CHANGE! I CAN'T BELIEVE THAT THE DEALER IS TRYING TO CHARGE ME $7,000 TO FIX THE CAR. THIS IS THE ONLY OPTION THAT THEY GAVE ME! I BELIEVE THE DEALER DID SOMETHING TO MY CAR OR THIS PROBLEM IS PART OF A RECALL FOR MY CAR THAT HAS NOT BEEN IDENTIFIED. THERE ARE RECALLS ON OTHER XF'S MODELS SIMILAR TO THIS EXACT PROBLEM, BUT DOES NOT INCLUDE MY SERIAL NUMBER. MY CAR ALSO EXPERIENCED ANOTHER RECALL TYPE ISSUE THAT DID NOT INCLUDE MY SERIAL NUMBER; POWER STEERING WENT OUT BUT THE CAR WAS UNDER WARRANTY SO THIS ISSUE WAS REPAIRED AT NO COST. MY CAR HAS ONLY BEEN SERVICED AT THE JAGUAR DEALERSHIP. IT WAS JUST SERVICED ON 01/02/2020. THERE WERE ALWAYS ISSUES AND PROBLEMS WITH THE CAR.
