2012 Honda Civic drivetrain & axles problems

My wife came to a stop at our security gate, used the remote for the gate but it wouldn't open. She backed up about 15 feet to turn around. When she put the car in drive, it lurched forward back towards the gate and wouldn't stop when she applied the brakes. It didn't speed up and it wouldn't stop. The car was making a grinding noise as it moved along. She was jamming on the brakes and it still went right through the closed gate, pushing it open as it went.

Tl* the contact owns a 2012 honda civic. The contact stated that while reversing into a residential garage, the vehicle accelerated forward as the brake was disengaged. On a different occasion, while driving uphill and releasing the brakes, the vehicle surged backward. In order to stop the vehicle from rolling backward, the contact had to continuously depress the accelerator pedal. The vehicle was taken to an authorized dealer, who stated that the failure was normal.
