Ford issued a recall on its 2002 Ford tauraus vehicles for updating the computer systems. After the computer systems were updated I was told that I need to purchase a new oxygen sensor to keep the light from coming on again. I asked if this was a part of the recall and the dealership stated no that is was something different. Well the same exact thing happened on my father-in-laws 2002 Ford escape. I took it in and was told the same thing. I asked again if it was part of the recall and they assured me that it wasnt. I think they are wrong. Well about a month later the car started accelerating on its on and jumping out of gear. This could have caused and accident but thankfully no one was in front of us at the time. Then the battery on it drained down so far that the big jump box at the dealership couldn't even fix it and we had to purchase a new battery. I'm not sure of the exact date of the incidents.
