My wife was driving her car at approximately 40 MPH when there was a loud thud. She then tried to steer the car to the shoulder, but had no control of the steering wheel. She got out and looked under the car to see what happened. The engine cradle had broken and was resting on the road. Had she been going 60 MPH on the freeway, she would have been in a major accident. I contacted a chevrolet dealership. They said there were two recalls on her vehicle: one for the engine cradle bolts, and one for the seatbelts.
