This incident involves a 1997 Mercury Grand Marquis gs and the failure (cracking) of the manifold intake which is in the process of leading to a high repair bill. I'd like to reference the Ford manifold intake settlement. This incident occurred approximately 9 months after the March deadline. We were not notified that there was an on-going settlement or an identified problem with the manifold intake. We request your assistance in providing any recourse in this matter and seeking reimbursement from Ford. Being a senior citizen and on a fixed income, it is extremely hard when getting hit with a huge repair bill especially when it involves a manufacturers defect. It is a shame that individuals like myself can be taken advantage of by big business and the seemingly hush hush attitude of this defect by not making this case well known. It seems individuals like myself have fallen through the cracks and request your assistance and guidance in this matter. I await your reply to my concerns. Thank you.

The contact stated the intake manifold failed twice. The first failure was in 2001, and the second failure was in 2005. The vehicle was towed to the dealership on both occasions where the engine was replaced at the contact's expense. The manufacturer has offered no free remedy. The engine had to be replaced in 2001, and in 2005 had to replace the intake manifold and pay to have it installed at Lincoln Mercury in concord, New Hampshire. When the intake manifold failed, antifreeze leaked all over the engine. After it was fixed, the intake manifold failed again. The contact had to pay for repairs, and there was no recall.

Driving down highway at 60 mph., when the plastic intake manifold suddenly ruptured dumping out all the antifreeze. High volume of traffic, we could barely get off highway, steam coming from my car blocking vision. Could have caused a major accident. Car had to be towed to local garage, then towed to my home and local garage for repairs. We had to rent car to get home. Mechanic said our intake manifold ruptured causing head gasket failure and possible engine failure. On 8-23-05, got class action suit papers in mail stating plastic intake manifolds could rupture causing coolant to leak and Ford would reimburse people who had the problem and paid for repairs. When I got the paper I went to mechanic and told him to stop repairs to see where I stood in suit. Suit did not mention gasket repair reimbursement and engine failure reimbursement. I called Ford today and got the usual story that their was no recall on my car, etc. However Ford did recall police cars, taxis and fleet cars with the same engine that I have. Ford knew about the poorly designed plastic intake manifolds for years and did not care about customer safety. We could have died from their neglect. W

Contact had to replace the entire- intake manifold on 1997 Mercury Grand Marquis. It blew anti-freeze all over his engine. This happened on 7-20-05, and he just got the car back on 7-26-05. Contact had a local service dealer replace the manifold. He would like to file a complaint because he felt this was a definite defect. The service dealer stated he had to replace a lot of other manifolds. Contact talked to Ford, and they basically told him that if they won the law suit against the manufacturer of the manifold they may get the $1,100 that he had to pay refunded to him.

A few months ago we found that our was over heating and found that we are leaking water somewhere in the system. We could not find a leak but had to put water into the radiator ever two days. We took the car to the shop to have the pros find the leak. We were told that their was w crack in the intake manifold and that it was a very common defect in Ford & Mercury Grand Marquis. They said that the manifold was made of plastic and they would all crack and brake. Every shop that I went to said the same thing and that they a lot of Grand Marquis waiting to be repaired. A replacement manifold cost $400 plus $250 in labor. We were told that if we continued to drive it, it would blow-up. We are afraid to drive the car and the parts are not available. I saw at least 20 Grand Marquis waiting for manifolds. I was told that Ford design them to brake. That's why their made of plastic. How stupid could they be to make engine parts out of pvc. What can I do? I believe that the cars should be recalled and replace the intake manifolds.
