“Today was the third time that I have refueled the car and have noticed that there is a strong gas smell when I park the car in the garage. I have looked with a flash light under the car (left rear below the tire rim) and I see gas dripping out of where a tubing connects to the fuel tank. This is a rapid drip that leaves a puddle on the floor. I have been cautious to not over-fill and still the problem persists.”

NHTSA complaint #706855, filed 1999-05

“Air intake plenum developed a crack which in turn sprayes coolant onto the rear of the alternator. I know there are many problems with this part but ford will not replace it.there is a limited recall on this part but it begins less than 4 months after the build date on my car, even though the problem described exists on many earlier models. I would like my car included in this recall but am told no way by ford. Any help in this matter would be greatly appreciated.”

“While driving along a busy city street on a cold evening in january I noticed a cloud of steam behind me. It obscured my view of traffic behind me and their view of my vehicle. After pulling of the right-of-way, and examining the engine compartment, I recognized cooling system failure but was unable to identify the source of the problem. It was later determined that the plastic intake manifold had ruptured and sprayed coolant all over the engine cmpartment,and hot exhaust manifold, etclocal ford dealers were closed and unavailable. …”

“Plastic intake manifold busted losing antifreeze,the sensor could not work, it only works with coolants, due to this the gauges did not work, until the the check engine light came on then I is to late. I was lucky I wasn't going 65 down the expressway when the motor locked up. I'm sure this has happen and cause accidents and no one knew what caused it. I have checked with 4 certified technicians they told me the problem happens often with this plastic intake manifolds. Why would anyone have a plastic intake so close to a hot! Motor. …”

“My primary complaint is the stress crack on the intake manifold. This is a known problem by ford, and has been the subject of a recall program for their fleet vehicles only. The coverage is for 7 years from the vehicles warranty start date, with no mileage limitation. It covers the intake manifold for 4.6 l sohc engines on 1996-2001 crown victoria police vehicles, certain 1998 through 2001 crown victoria taxis and certain 1998-2001 lincoln town cars, all using the same intake manifold as that on my Grand Marquis (same part number, same part!). The recall program is 01m02. …”
