What component or system failed or malfunctioned, and is it available for inspection upon request? The break pedal stop pad broke into small pieces while I was driving today. My car suddenly would not go above 40 and while going up a hill I couldn’t go faster than 20. When I finally got home I realized that my break lights would not turn off. I did google and it said to look on the floor board and see if there was anything on the floor. The pieces I found were identified as the break pedal stop pad. Yes it is available for inspection and I took pictures of the broken bits from the floorboard. How was your safety or the safety of others put at risk? My car suddenly was unable to go the speed limit in 6 o’clock traffic putting me as well as those driving behind me in danger of a collision and physical harm.

No Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear?

There is a circular pin in the brake pedal that interacts with the brake switch sensor that basically disintegrated. Not having this part does not allow me to brake properly and caused me to get into an accident and would not allow my car to accelerate properly. Also, without this part the car will not turn off. The dealership told me that they had never seen this issue; however, I have found many incidents on the internet where this is a common problem in Ford vehicles. There were no warnings at all.
Brake switch pad on the break pedal failed and fell out
Cheap plastic disk between the brake pedal assembly and the plumber rod that should only control lights dried up and broke off. This issue has been reported many times and you have not handled it properly. Not only do the brake lights come on but the uphill traction control goes crazy and the vehicle begins to lose power without notice. This could result in an accident and death as the car could be on a highway and suddenly lose power. Ford doesn't offer a replacement part for this. Other car manufactures have a similar plastic part. Fords solution is to spend nearly $1000 for a > $10 item. This needs to be taken more seriously than some of your other recall items you report.
TL* THE CONTACT OWNS A 2015 FORD MUSTANG. WHILE OPERATING THE VEHICLE, THE BRAKE LIGHTS REMAINED ILLUMINATED. THE CONTACT ALSO INDICATED THAT THE FAILURE WAS PRESENT WHEN THE VEHICLE WAS TURNED OFF. THE VEHICLE WAS TAKEN TO THE LOCAL DEALER (MULLINAX FORD OF PALM BEACH, 1210 NORTHLAKE BLVD, LAKE PARK, FL) WHERE IT WAS DIAGNOSED THAT THE BRAKE PEDAL ASSEMBLY WAS FAULTY AND NEEDED TO BE REPLACED. THE BRAKE PEDAL ASSEMBLY WAS REPLACED AND THE FAILURE WAS REMEDIED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 22,943.
I HAVE A MANUAL TRANSMISSION. VEHICLE WAS PARKED WITH THE EMERGENCY PARKING BRAKE FULLY ENGAGED. VEHICLE ROLLED DOWNHILL AND CRASHED INTO A FENCE. CONTACTED DEALER AND THEY SAID VEHICLE WAS NOT COVERED BY ANY RECALL.
THE BREAK PEDAL IS TOO CLOSE TO THE ACCELARATOR AND IF YOU PRESS DOWN FAR ENOUGH OF THE BRAKE, YOUR FOOT MAY ALSO TOUCH THE ACCELERATOR, THUS CAUSING THE CAR TO ACCELERATE WHILE YOU ARE TRYING TO SLOW DOWN OR STOP. I CONTACTED THE DEALER AS WELL AS THE DISTRICT OFFICE, BUT THEY FOUND NOTHING WRONG. FINALLY, THEY HAD SOMEONE RIDE WITH ME AND THEY NOTICED THAT AT A CERTAIN POINT, MY FOOT WAS COMING IN CONTACT WITH THE ACCERARATOR BY MAYBE 1/8". THE DEALER SAID THEY COULDN'T DO ANYTHING ABOUT FIXING IT BECAUSE THERE HAD BEEN NO RECALL ISSUED. I HAVE HAD NUMEROUS OCCASIONS WHERE I HAVE ALMOST BEEN IN AN ACCIDENT BECAUSE OF THIS, EVEN AFTER I BECAME AWARE OF THE ISSUE. I CAN'T BELEIEV THAT I AM THE ONLY ONE IN THE COUNTRY WHO HAS HAD THIS PROBLEM, AND MY FEET ARE NOT THAT BIG. I BELIEVE BY MOVING THE BRAKE PEDAL TO THE LEFT ABOUT 1/4" WILL RESOLVE THE ISSUE. THE DEALER SAID THEY WOULD DO IT WHEN/IF A RECALL WAS ISSUED. AS STATED BEFORE, THIS HAPPENS WHEN THE BRAKE PEDAL IS DEPRESSED BEYOND A CERTAIN POINT, WHICH IS USUALLY WHEN HARD BRAKING, OR A QUICK SLOWDOWN IS REQUIRED AND THERE IS NO TIME TO THINK ABOUT WHERE YOUR FOOT IS IN RELATION TO THE ACCELERATOR.
