Driving down the road straight, our car made a pop sound and suddenly lurched and steering was impaired. Car was taken to the nearest dealership where they found the engine cradle/front sub frame had rusted through internally causing the sway bar to break away and it had perforated around the mount for the control arm. We were extremely fortunate the control arm didn't completely drop out causing an accident. Failure is almost identical to the Ford escape subframe recall. Dealer technician said he has replaced a lot of these engine cradles in the Taurus x's for the same failure (some worse than ours, completely rusted in half etc. ). Lack of sufficient paint inside of the cradles causing premature failure is a major safety concern. I would not be surprised if there are accidents reported for this concern. I have requested the engine cradle from the dealership after it is removed for photographic evidence.
