Bought the car for my son August 2. The engine light came on the end of October, the Ford dealer was backed up once they took a look at it in the beginning of November. They told me I needed a whole new engine due to a coolant intrusion problem. Where I bought the car from state it came with a 12 month/12,000 mile warranty but warranty company is not covering that issue. This should be a recall and the engine should be completely covered.
