I’m reporting this safety concern and seeking advisement from those more knowledgeable than myself on this issue. Recently, as I attempted to actuate the brake of my vehicle. My right foot was entangled with the brake pedal as I moved it from the acceleration pedal to the brake pedal in observance of a “Stop Sign.” I barely avoided what surely would have been a catastrophic collision with another vehicle. The incident occurred in a split second. The shoe of my right foot was entangled with the lower right corner of the underside of the brake pedal, which has a protruding sharp thin metal edge. The sharp thin metal edge impeded the performance my right leg as it dug into my shoe’s sole edge and the leather upper. In my opinion the sharp thin metal edge of the underside of the brake pedal as described herein is a dangerous and extremely problematic issue. After the recent incident, I am consumed with concern, trepidation and fear when operating the vehicle. During the excitement of the near collision, my wife made an audible gasp, and in the split second I struggled to free my shoe and foot to avoid a potentially fatal crash. I barely freed my foot and shoe in time enough to successfully bring my vehicle to a halt. My wife and I narrowly averted a life changing, potentially deadly accident.

THE FRONT ROTORS SEEM TO RETAIN BRAKE DUST JUST ON THE INSIDES OF THE ROTORS. THE OUTSIDES ARE VERY CLEAN AND SHINY BUT ON THE OTHER SIDE OF THE ROTOR (INTERIOR) BECOMES VERY COARSE CAUSING VIBRATIONS IN STEERING. KEEP IN MIND THAT THE INTERIOR IS PROTECTED BY THE BRAKE SHIELD WHICH MUST BE CAUSING HEAT NOT TO BE DISSIPATED THEREBY FOSTERING BRAKE DUST TO AMASS. SUCH VIBRATIONS WILL ALARM DRIVERS TO PANIC AND CAUSE ACCIDENTS.
