I bought a 2003 ford focus in late 2003 and have had the car maintained to the letter since it was bought. I recently took the car to the Ford Motor dealer where I have always had it serviced at and they changed the oil and the brakes and exactly 14 days later the engine went clean out! Their explanation was that the valve seat dropped and destroyed the oil pan and that they was in no way responsible and that it would cost 4200 dollars to replace the engine! The car only had 46000 miles on it! Does this make sense to anyone and how should I deal with this situation?
