Defogger Heater problems of the 1996 Ford Taurus

I have a 96 Ford Taurus (VIN 1falp52u4ta107398) I have had to have the heater core replaced 3 times in this car since I have had it, the most recent times being 6 months apart. This is a very costly repair (labor is 675. 00) I called Ford to complain and was told no recalls and no problems with this. I found out today that there has been problems with the heater core and a TSB had been released about it. I think Ford should have to refund me the money I have spent on having it fixed and have it fixed according to the TSB also! I have had lots of problems with my car since I bought it and all of them seem to have some type of TSB out about them, why is Ford not responsible for fixing these known problems??.

Heater core broke or ruptured and antifreeze came out of the vents inside the vehicle. It put a greasy film on windows like fog or steam. Heater will not work. Contacted dealer ,and dealer couldn't continue to fix vehicle becaus e warranty has run out.

Heater core failed.
