Defogger Heater Problems of Mercury Sable

Ford taurus and the Mercury Sable's have a problem with water leaking into the heater core box which eventually causes the heater motor and stop working. I understand from reading post on the internet that is apparently a design flaw. My car had 44,000 miles at the point where the motor quit working. The bill to repair the car was $471. 28. The warranty had obviously expired but I felt like Ford motor CO should re-imburse the cost of the repair since it is a very common problem. They declined to help with the cost of the repair.

- the contact owns a 2001 Mercury Sable with an odometer reading of 71750 miles. The contact stated that the hoses that ran through the heater core dry rotted and failed, which caused the vehicle to overheat. The contact was driving under normal conditions at 40 mph when the failure occurred. The contact took the vehicle to the dealer to have the problem repaired. The failure mileage was 68,680. The vehicle was leaking coolant at the tubes to the heater core. The front brake pads were very thin. Updated 04/12/07.

I am having major heating issues that the heater core will not warm the car and the metal tubing began to leak at the t that is on the fire wall of the vehicle.

We own a 1997 Mercury Sable. In June of 2004 our heater core went out and, as the car was under warranty, was replaced by a local car dealership, henry day Ford. The mileage of the car was then 60,468. Since then, we have had to have the heater core replaced an additional 4 times, the last time was may 11, 2005 (mileage 64,995). On June 7, 2005, once again, the heater core seemed to go out. We took it to henry day and they informed us that the head gasket was warped and needed to be replaced. Each time this has occurred, a steam has filled the interior of the vehicle and clouded the windows, making it impossible to see where I am going. It is a very malodorous steam, full of antifreeze. My concern is that this is a safety hazard. I have spoken to several owners of Ford taurus and Mercury Sable vehicles, and most seem to have had a similar problem with multiple heater core problems. This would appear to be a flaw in the vehicle. I am concerned that it will cause an accident for me, and I wonder how many accidents have occurred because of this problem. I am also concerned about my health and the health of my spouse (who has heart problems). We have been nauseated and have had congestion and even some memory problems that seem to occur after inhaling the steam. We would like information on the effects of inhaling this mixture of water and antifreeze.
