Just about everything that could go wrong with this car has gone wrong. Two months after I got the car the transmission blew out (left me stranded in the middle of New Mexico in the snow). Cost $2000 to replace. Heater core went out ($200). Transmission went out again ($2000), fuel pump ($180), engine leaks oil constantly, transmission leaks constantly, replaced the motor mounts two different times. Major problems with leaking radiator (probably because it's made of plastic).
All in all I've spent about $5000 trying to keep this car alive. I can't go anywhere without wondering if it's going to break down again.
STAY AWAY FROM ANY FORD TAURUS, THEY ARE NOTHING BUT TROUBLE!!! The only good thing that I can say is that it has a very comfortable ride (when the car is actually working).
Spending $2000 for a new tranny and labor on it is understandable, but to do it twice you need to look for another mechanic - always get the ford factory reman with the 3yr/36k mile warranty.
