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!.

My 2006 Grand Marquis original plastic intake manifold developed a crack at the drivers side rear intake bolt area causing it to leak antifreeze. This caused me to have to spend $240. 00 to buy a new dorman replacement and install it. Ford continues to use these cheap plastic manifolds despite losing a class action lawsuit against them for this problem. There will be more of these plastic manifold failing in the near future to be sure. This problem should be addressed by a new class action lawsuit due to fords continued incompetence as a manufacturer. My car also suffers from a defective eatc air conditioner control that blows air out of the wrong vents and won't activate the ac. Also a bolt broke on the drivers side front seat due to rust. Also the digital compass has quit working. Also had a water leak in the back passenger floor area.

Vehicle would shake violently at any speed from 45-80mph. Took to a mechanic said the front end needed to be replaced. $800. 00 later it still did it, then took back said the tires needed to be replaced although we had 80,000 mile tires, and only had 35,000 miles put on them. Replaced the tires for $600. 00. Still shook, took to a different mechanic said it was the transmission failing. During scheduled maintenance found cracked intake manifold, antifreeze and oil in spark plugs, cleaned out changed spark plugs, ran fine until the manifold leaked more coolant into the spark plugs and now we are at square one. Researched online found a bunch of places saying it was recalled, when I called the dealership they said no recalls. Price of replacing the part was $615. 00 if I had one alternator, or $650. 00 if I had another.

I observed a coolant leak around the thermostat. I found the plastic intake manifold to be cracked around the thermostat and leaking coolant. I made contact with Mercury and found that there had been a recall on the plastic intake manifold in which they would have replaced the part at no charge during the safety recall campaign. I was not made aware of the safety recall and have owned the vehicle since 04/17/02 when I purchased the vehicle used from a Mercury dealership. The dealership would no longer honor this recall although there are still thousands upon thousands of these engines still on the road. The all plastic manifold was replaced with an intake manifold with an aluminum crossover channel for the coolant. I was forced to replace this defective part out-of-pocket at a cost of $800. It would have been more had I not been friends with the mechanic. The vehicle had 102,281 miles at the time of the failure.

Plastic intake manifold on a 1996 Ford Grand Marquis 4. 6 liter v-8. Apparently there was some settlement offer from Ford to replace this part with an aluminum intake however due to the car not being driven much, 70,000 miles in 12 years the intake manifold did not fail until recently. I would like to know what options I have in fixing this part and possible reimbursement of the $800 or more it will cost me to fix it.

Cracked intake manifold on a 1999 Mercury Grand Marquis with only 52000 miles on it. Cost $1200 to repair. Was not notified of recall. 52000 miles is only about 4. 3 years of actual use. It is unfair that low mileage drivers should be punished for conserving energy.

Had just turned off freeway when warning chime for overheated engine sounded. Stopped car within one block & turned off motor. Towed to mechanic. Turns out to be the intake manifold catastrophic failure, common to fords (mine is 1996 Mercury Grand Marquis, 71k miles. ) am now running compression test to see if any engine damage, if there is no damage then I will have to fix manifold at a cost of approx. $1036. If there is engine damage then I will have to junk a perfectly fine car in excellent condition (apart from this). Ford does not offer any redress. I never received any information about this problem, nor about the class action lawsuit settlement. This could have been extremely dangerous, as I had just excited a freeway when the warning beep sounded. I have received all other recall info on this vehicle and have complied w. Recall. In fact vehicle had been fully checked by dealer only 6 days when taken in for the second part of the switch recall on this model. Dealer never informed me of any potential manifold problem. This is a safety issue as well as a defective part issue. At the very least, owners should be notified that this is a common catastrophic failure.

Just left highway rest stop in kentucky, no signs of coolant leakage or any problems. Within 5-7 miles at 65mph, a beep, beep sound, then temperature gauge rose immediately to high , began to slow vehicle & turned heater on. Steam was scene from under the hood as we approached a construction area. We barely made it to a closed weigh station. Failure was sudden & catastrophic. Had we remained on the highway, an accident would have surely occurred, no shoulder was available. Two hours waiting for a tow truck, which finally took the vehicle to the nearest Ford dealer. Being a Sunday, we had to obtain overnight stay in a hotel. Monday the dealer diagnosed the problem as a cracked intake manifold. Dealer replaced the part, including thermostat & coolant.

Had spark plugs replaced. One plug exploded. Was told by Ford dealership service mechanic the intake manifold was cracked. Car was running fine before plugs were replaced. Intake manifold is plastic. (this was an issue with the 1997 model. ) did the repairman crack the manifold? why is replacement part still plastic? Ford/Mercury price for part is $598. 06; napa is $281. 00.

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.

Engine failure due to a defective plastic engine intake manifold. 2000 Mercury Grand Marquis began to hesitate; the dealer said it was caused by a defective nylon intake manifold, and they would not cover the cost of repairs. Ford has had many complaints on this defect.

I was driving my 1996 Mercury Grand Marquis when steam started pouring from under the hood. I had to have my car towed and learned that the intake-manifold had cracked, causing coolant to pour all over the engine. The garage replaced the unit for a charge of $692 and told me everything was then fine. However, before I got home, my engine light came on. I took my car to the very reputable automobile repair shop that I use and upon checking, they said the wires, points, and plugs needed replacing, no doubt caused from the prior incident. This work cost me an additional $425.
