On 7/3/2007 I heard a loud banging sound and smelled gas coming from under my engine. When I had it towed to sioux falls Ford, they said a spark plug had blown out. When I asked if that was a factory defect, I was told that the plug may have been put in incorrectly. I have never had the spark plugs replaced, so I knew it was a factory plug, but the technician said that they had no way of knowing that. I spent $800 to have the it re-thread. 4 weeks later, a different spark plug did the same thing. At that time, they told me that they would check all of the spark plugs to ensure that they were tight. 4 weeks after that, the ignition coil needed to be replaced in that plug and the plug needed to be replaced. They claimed that their repairs had not caused this, but I feel like I have been getting the run-around on all of this simply because I am a woman.
