While driving the vehicle at highway speeds (60-70mph) going uphill, while making a sharp turn left or while rocking the steering wheel to make the rear of the car sway slightly to the left, there is a surge and complete loss of power for 1/2 second. This causes a surge/jolt feeling in the vehicle like the vehicle transmission or engine has lost all power. If you try to sway the vehicle immediately a 2nd time nothing happens. If you wait several minutes and sway the rear end again there is again a heavy surge and loss of power. I also observed the tac-ometer show a loss of power for a brief moment. If you are going up hill at highway speeds and the vehicle sways to the right or you swerve the steering wheel to make the vehicle swerve to the right (body rock to the right) nothing will ever happen. It is only on left body rock while at highway speeds on an incline. There are no trouble codes. There is no indicator light or dash flash or buzzer. Nothing happens and nothing triggers a diagnostic code. All codes are clear. There are two bulletins posted on the NHTSA website. 1. id# 10024695 & 2. id# 10039053. When calling Ford @ 800-392-3673 they are unable to provide any information or help regarding this matter or the bulletins mentioned. They advise there are no bulletins at all for my vehicle. This problem started when the vehicle was brand new. The dealership in California was unable to diagnose the problem because it was intermittent. Now at 54,000 miles the problem happens 8 or 10 times in a 30 mile trip. It is very troubling that the vehicle loses power and surges. It causes a panic in the passenger compartment when happening!
