2011 Ford Fusion drivetrain & axles problems

Tl* the contact owns a 2011 ford fusion. While driving 60 MPH, the contact heard an abnormal noise coming from the vehicle. Prior to the noise, the contact noticed a burning odor. The vehicle was taken to an independent mechanic who found grease inside the transfer case. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 60,000.

While entering interstate 275 south on ramp in tampa, fl my car abruptly stopped responding to the gas pedal and the little wrench light came on. All I could do is coast to a stop on the side of the road. Once my speed slowed to around 5 to 10 miles per hour, the car began to jerk and shake. I put it in park, turned it off and restarted the engine, and it worked like normal for about another month or so until it happened again while I was turning right on red on a major 5 line street.
