Spark plug ejection from cylinder head
On september 6, 2005, odi received a petition requesting that the agency investigate allegations of engine spark plug ejection in certain model year 1997 through 2004 ford vehicles with triton v-8 and v-10 engines.odi received a total of 474 non-duplicative complaints on the subject vehicles where the complainant, or the dealer repairing the vehicle, reported that a spark plug detached from the cylinder and/or ejected from the engine.as of december 8, 2005, odi is not aware of any allegations where the alleged defect resulted in a loss of vehicle control, a crash, an injury, or a fatality in any of the 10,319,810 subject vehicles.in addition, odi is aware of only two incidents where the vehicle stalled without restart.information contained in the odi consumer complaints and obtained from 72 telephone interviews with complainants showed the following:(1) 99% of the complaints were on my 1997 to 2002 subject vehicles.(2) most the complainants reported hearing a loud pop while driving or upon starting up the vehicle followed by a loud, repetitive clicking or popping sound.(3) many of the complainants reported that the popping sound was accompanied by some loss of vehicle power; however, in 99% of the incidents reported, the vehicle did not stall.in the very few incidents where the vehicle did stall, most vehicles could be restarted.(4) only a small percentage of the complainants cited that they smelled gas or a slight burning smell when the incident occurred.(5) in all but a very few incidents, vehicle damage was limited to the engine.in one incident, the complaint reported that the fuel rail was damaged and replaced after one of the spark plugs ejected from the engine; however, the complainant reported that the damage did not result in any type of fuel leak or fire.in another incident, the only incident where a fire was alleged, the complainant reported that no fluid leak was observed, but that a fire resulted after the spark plug had ejected from the engine and he had restarted the vehicle and driven to another location.none of the complainants reported any damage to the vehicle hood.(6) only two complainants reported that they observed what appeared to be some drops of fuel coming from the cylinder where the spark plug had failed or on the spark plug itself; however, each of these complainants reported that there was no smoke or flames as a result of his incident.as the petitioner noted, and odi?s analysis showed, it is possible for a spark plug to detach from the engine cylinder threads in the subject vehicles.however, odi?s analysis of 474 complaints describing such incidents found only a very few alleged any safety-related consequences.none of these showed any evidence of a serious safety consequence.given the large population and relatively long exposure time of the subject vehicles, the complaint analysis indicates that the risk to motor vehicle safety from the alleged defect is very low.in view of the foregoing, it is unlikely that the federal safety agency would issue an order for the notification and remedy of the alleged defect at the conclusion of the investigation requested in the petition.therefore, in view of the need to allocate and prioritize the federal safety agency?s limited resources to best accomplish the agency?s safety mission, the petition is denied.

What 2001 Mercury Grand Marquis owners say
Most recent owner complaints, unedited.
PLEASE NOTE: This complaint/issue pertains to many nearly identical plastic intake manifolds sold as OEM, new or replacements for cars made in the last ten years- Dangerous perhaps fatal fires are likely not getting reported due to the nature of the cause. My car has a plastic manifold. When a fuel injector or fuel regulator fails, raw gasoline can collect in the plastic bottom. If more than a few drops collects, turning over the engine can cause, and did in my car, a massive explosion. Fortunately the blue & white cloud of smoke that filled my two-car garage did not ignite. Had it ignited my son and I might not have survived and our home may have burned. Not that your organization takes all complaints seriously, particularly when thousands of cars might be involved, but these cheap plastic manifolds present a real danger I believe could have already caused deaths and property damage. If you are a political entity I suspect you will ignore this. But at least a warning should be give to the public. We are replacing the fractured manifold but the replacement part is still plastic, too thin to survive what cars in the past would have survived easily.
A lot have happened still trying to figure out the problem it want crank now

Tl* the contact owns a 2001 mercury grand marquis. The contact stated that white smoke appeared from the vehicle. The vehicle was taken to an independent mechanic who stated that the failure was due to the intake manifold. The vehicle was taken to malouf ford lincoln, inc (2210 us-1, north brunswick township, nj 08902, (732) 951-0300) where it was suggested the plastic defective intake manifold was the cause of the failure. The contact called the manufacturer and asked to speak to a case manager. The manufacturer was to call the contact back or mail a response. The failure mileage was 135,000.
The 1996-2001 mercury grand marquis with a 100% plastic intake manifold is known for engine overheating, even with normal use, and a coolant leak from the front of the manifold. This will often trigger the check engine light and low engine coolant warning light. The engine coolant leak is from a factory defect, which causes cracking on the front coolant passage of the intake manifold. In a very short time, this leak will lead to engine overheating issues, especially while the vehicle is idling. This is exactly what happened. I think the car part should have been replaced by ford when they new about the plastic intake manifold.
