Owner report 11352199 · 2020-08-31 (August 31, 2020)
I MADE A SAFE DRIVING TRAINING WITH MY NEW 2020 FORD MUSTANG GT (EU MODEL) (AS I DO FOR EVERY NEW CAR I BOUGHT). DURING THE FIRST BREAK TRAINING (EMERGENCY BRAKING FROM 50KM/H (~31MPH) TO 0 ) THE BREAK PEDAL BROKE. LUCKILY JUST RIGHT BEFORE THE VEHICLE STOPS AND NOT AT THE BEGINNING OF THE MANEUVER. IT WAS NOT POSSIBLE TO MOVE THE VEHICLE ANYMORE, AS THE PEDAL WAS LOOSE NOW AND BRAKING NOT POSSIBLE ANYMORE. I THINK MAYBE OTHER BATCHES OF THIS PLASTIC BREAK-PEDAL HOLDERS MIGHT BE AFFECTED (PLEASE SEE ATTACHED PICTURES).

We took it to the dea…
