Heard clunking noise-rear subframe is completely rotted and broken on both sides.
My last oil change I was inform the front subframe is badly rusted, to the point the mechanic could push a screw driver through it in spots. He informed me that driving it was a major safety risk, as the frame could fail, causing an accident. He said Ford has not issued a recall. They must be waiting for a higher body count when the front end of the car fails while going down the interstate.
