Defect investigations
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.

My 03' mustang spit the spark plug out of the head,again, taking all the threads with it. Now it is unable to run do the fact it has a missing plug. The dealership says it is out of their hands do to not being under warranty any longer. Ford motor co. Said they will not fix the car,it is out of warranty. Sorry the spark plug was ejected out of the head. We can not fix it unless you pay for parts/labor out of your pocket. This is a very well known issue for ford, I do not understand why the are acting like there is not 1000's of people this has happened to. My next step is to hire a class action attorney and see about getting my car fixed.
Spark plug was spit out of head. It has the factory plugs in it never been changed. The dealership said that nothing was wrong with my car,the dealership, checked spark plug in question,then told me that there was nothing wrong with my car and sent me on my way. At this point I do not know if it is ok or not? But I am driving it till it breaks again.
On cold start, there is a "ticking" sound. Took it to mechanic and he gave me a technical service bulletin article #03-25-6, dated 12/22/03, regarding ford, lincoln and mercury engines built before 9/17/2003. Emailed ford motor company to find out what could be done to rectify the situation as it is a known defect of the car although it is not a safety issue. All they could tell me is there is no recall and take it to an authorized dealer to have it diagnosed and repaired if need.
Interior A/C blower fan(dashboard vents) stops working after in use for 1 hour.
1) everything was running fine, no problems detected. Maintenance on vehicle was up to date. Was turning a corner and there was a pop and after that the engine started to mis-fire. 2) was able to limp the 2 miles to the ford service center. There, they told me that the spark plug had blown out of the engine block and that this happens on occasion. I had two options: the first was to pay $610 to put a patch in that wasn't provided with a warranty and they told me it could last 2 years or blow 2 miles down from the shop after I left, or pay $2500 and have a new cylinder put in. After researching this issue, I found that this is a very common occurrence with ford vehicles, that ford is aware of but is not taking care of. I was also told that even if the car was still under warranty that the warranty would not cover this and I would still have to pay out of pocket. I am now stuck with a car I can't afford to fix for a while and a car maker who can't admit that they built a faulty engine and fix their problem. 3) nothing has been done to fix this yet, as I am looking for someone who can fix it right at a lower cost.
The intake manifold blow a hole at the crossover exchange, causing coolant to explode out like a guyser and got on my face when I opened the hood to see what the smoke was coming from! It is out of warranty and I was never notified about a recall or class action settlement in 2005. Can I be reimbersed the product has been knowingly and widely viewed be evrybody as defective.
In my 2003 mustang gt with tremec tranny...grinding type feeling going into second gear. Went to dealer, and they said feeling was normal,and it would go away,it has not. I only drive it once and a while but it is worse on colder days!!!
