1 Engine Exhaust System problem of the 1996 Mercury Grand Marquis

Failure Date: 11/27/2010

While driving my vehicle home from work in the evening, the car started to putter, then smoke came pouring out from under the engine hood blocking my view from the road causing cars to race around me and almost had an accident. . . Also started coming in the vents of the car, making me nausea. Extreme danger and fear. I had to have the car towed $65. 00 and the repair estimate came in at $900. 00. Cracked plastic intake manifold. ??plastic?? who does that? I have been unemployed and only able to get part time employment. I can't afford this repair so I had to have the car towed back to my house. . . Another $65. 00. The car only has 85,218 miles on it and has been kept immaculate. I contacted Mercury/Ford and they said there is nothing they can do. In researching, I spent hours reading hundreds and hundreds of postings regarding the same situation. . . And also, the same car, Ford crown victoria has the exact same problem. I understand there was a "silent recall" where only government fleet/police cars were taken care of. How nice! the replacement was with a metal part, which it should have been from the beginning. This is an extreme neglect on Ford/Mercury part. I believe that the investigation and action should be based on the quantity of both the crown victoria and Grand Marquis combined, since they are the exact same car manufactured. Please help!.

2 Engine Exhaust System problem of the 2000 Mercury Grand Marquis

Failure Date: 10/10/2008

Car started running hot all of a sudden. . Found out the intake manifold was cracked and the coolant was leaking on spark plugs and fuel injectors. Causing the car to misfire and slow to pick up speed. Tried to get fixed but was told the exp. Date was in 07. So I have to pay out of pocket. . I feel a recall shouldn't have an expiration date cause it tells you that one of these days the part on the car is going to need to be fixed. I feel Ford should live up to their word and fix the problem no cost to customer. . .
