Manifold/header/muffler/tail Pipe problems of the 2004 Mercury Grand Marquis

Tl-the contact owns a 2004 Mercury Grand Marquis. The contact stated that while driving at 30 mph, smoke emitted from the engine compartment of the vehicle. Upon inspection, the contact noticed that there was no coolant in the vehicle. The coolant was replenished and the vehicle was taken to an independent mechanic where it was diagnosed that the intake manifold had fractured and needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was unknown. Ss.

The contact owns a 2004 Mercury Grand Marquis. The contact stated that the exterior headlamps independently failed. The contact stated that the headlamps would sporadically work after a period of time. The vehicle was not diagnosed nor repaired. Prior to the failure, the intake manifold leaked anti-freeze. The vehicle was taken to the dealer where it was confirmed that the intake manifold needed to be replaced. The vehicle was repaired. The manufacturer was notified of the failures. The failure mileage was 96,794.

The left hand (driver side) heat shield that covers the exhaust manifold has completely rusted at the bolting points causing the cover to dislodge and drag against the steering shaft . Several timse while turning at intersections, especially when making left turns, the steering would temporarily lock up for a few seconds making turning extremely hazardous. Once I almost struck another vehicle due to the steering being locked while turning. I initially suspected low power steering fluid but fluid checked correct and pump seems to be working fine. I did not notice the rusted cover pinned between the steering shaft and manifold until I removed the engine cover and air intake tubing to access the spark plugs. I removed the rusted shield and the car turns just fine now. I have the rusted shield available for inspection if needed. Thanks.

Tl- the contact owns a 2004 Mercury Grand Marquis. The contact stated that there was a continuous coolant leak intermittently. The vehicle was towed to an authorized dealer who diagnosed that the intake manifold needed to be replaced. The vehicle was repaired. The contact stated that the manufacturer did not disclose that the part was modified from plastic to metal. The contact had experienced multiple leaks before the part was modified to metal. The manufacturer was notified of the failure. The approximate failure mileage was 85,000. Dyd.

I had what seems to be a simple coolent leak but it turned out to be the plastic intake manifold cracked. Putting a plastic part on top of a motor seems to me a failure of engineering on the part of Ford. I did not receive any call back for this part. I did some searching on the web and found that many Ford owners had the same problem. I plan to call Ford company on Monday. Do you have any info for me on this subject. Thank you.

Intake manifold cracked, needed replacement. This is a plastic component which is not designed for cold weather climates. This is the second time (second car) that this has happened to.

Crack intake manifold because it's plastic. I had to pay for the repair and I was not at fault.
