Automatic Transmission Floor Shift problems of the 2004 Jaguar S-type

Upon purchasing the vehicle from the dealer in used condition w/ roughly 50000 I immediately began to notice shifter problems, especially if the vehicle was parked on an incline or decline. Shifter will become stuck and will not come out of park without great force, which then breaks the plastic piece which is necessary to change out the gears, resulting in complete immobility of the vehicle since the car was then stuck in park. Car would have needed to be towed if not for being able to take off the console piece to change out the gears w/ a screwdriver in order to just get the car to the dealership. This was less than a month after purchase. Upon complaint the dealership replaced the plastic piece or housing and attempted to charge $400+ but was told that it would not be paid due to having the vehicle less than a month. Not surprisingly,less than one month after repair the exact same thing happened again and once again the screwdriver aided in getting the car to the dealership where they went through the exact same procedure and "fixed"the problem again, this time at no charge. I am confident this problem will happen again, as the shifter still sticks just like it did before it broke either time and I am just counting the days till I am forced to once again break out the screwdriver and waste another full day getting it replaced.
