MY 2004 Mercury Grand Marque over heated in June while I was waiting on a red light to change, dumping all fluid and stranding me.
I waited 2-weeks for my son to check out the car and he changed the thermostat and I drove it to the doctor next day and it over heated again. We added more antifreeze and I have not had that problem since, just a new host of problems. The A/C will only flow hot air, the passenger window if, I put it down it can only be put back up by force, the door can not be locked with the remote, I purchased a inside window washer and the long handle makes it easy to lock the door. My headlights went out and I also received the recall letter in April about that problem, the headlight problem did not occur till early on a very dark November morning when I was on my way to take my sister, for surgery, to the hospital.
My car is now at the dealership for all electrical problems to be fixed and I understand the headlight part my not be available for months. Happy days are ahead.
