(1) driving on interstate highway car engine suddenly lost power while changing lane. Was almost hit from behind but luckily the other car was able to stop. (2) the engine in my car, '99 Ford Crown Victoria, had blown a spark plug. (3) repair involved changing the cylinder head in the engine or replace the whole engine that I opted to do. At first I thought this is just a single incident but I later learned that there are a lot of people who have experienced the same mainly on Ford pick-up trucks but also on other vehicles with the same engine / cylinder head design. A Ford dealer who did the work for replacing the engine said they have not heard about this before. I have later also learned that a lot of people experience the same with Ford, I.e. they claim not knowing about the issue but they must as so many people have complained about this. In my lifetime I have always believed that car engines wear out over time. It is not a normal mode of failure that car engine blows spark plugs and causes thousands of dollars of unexpected cost to consumers like me. Nearly $5000 'christmas present' was not in my plans. What does it take to get Ford to stand behind their product in this case" as it might not sound a safety issue at first just think what might happen if a spark plug blows during a passing of another vehicle on a 2-lane highway when another vehicle is approaching in not so far distance" it becomes a safety issue in a hurry! about this issue can be read in the interned. Jus search blown spark plug and it's all in front of you. Thank you, ari rousu

Engine on my car just stopped working and when towed to facility the mechanic informed me the engine was gone. Warranty people came to look at the vehicle and stated I used bad gasbecause carbon had built up on the rings and would not honor warranty. All fluids were clear and car has been properly maintained.

While driving lost all engine power, but engine never stalled. When stepping on gas pedal nothing happened. It happened before on a incline hill, and could not hold vehicle from rolling back. Then, took vehicle to dealer, and they did not find anything. Consumer believed problem was traction control.
