I was slowly pulling forward, parking my vehicle. I pressed the brakes and they did not engage. I pumped my brakes and my foot was down to the floor with no brake activity and an involuntary acceleration occurred causing me to crash into a brick wall. Fortunately, I was the only person injured in the crash. The police were called and my vehicle was towed to be repaired. It was inspected by my insurance company. I called Ford several times to ask that the vehicle be inspected by a Ford investigator to determine why the brakes failed and the involuntary acceleration occurred. They misdirected me at least 10 times. I informed that there were 12 reports of the identical problem happening to other 2019 Ford Ranger owners. They ignored my requests. Upon recommendation by Ford Customer Service, my car was towed from a body shop to a Ford dealer where they informed by that there was at least one instance that the diagnostics showed a sensor failure. At no time did any warning light appear on my dash signaling me there was an issue of a sensor failure. In spite of this problem, Ford continues to ignore my request for an inspection of the vehicle. I went to a Doctor as I had a very bad headache and pain throughout my body. I had a concussion and soft tissue damage along my right side, both hands and elbows.
