I was driving down the street with my foot in the gas going about 35mph. No cars in front or behind me. All of the sudden my car brakes for no reason. It was a hard brake. My foot was on the gas pedal when this happened. Then a bunch of warnings displayed on my screen: forward smart city brake malfunction, front camera sensor system malfunction, brake override system malfunction and smart brake malfunction. My check engine light, traction control light and parking brake light also came on. This was extremely dangerous and could have caused an accident the way the car decided to brake all by itself.

MAZDA SMART BRAKING SYSTEM, FRONT RADAR WARNING LIGHTS COME ON AFTER CAR IS STARTED. WINDSHIELD AND FRONT EMBLEM IS CLEAN. NO INTENSE HEAT. COMES ON EVERY TIME WHEN STARTED. WILL NOT ALLOW CRUISE CONTROL TO BE SET. SOMETIMES A FUNNY BRAKE PEDAL FEEL WHEN APPLIED BUT DOES NOT BRAKE BY ITSELF....YET. THERE HAVE BEEN TSBS ON EARLIER MODELS WITH A REPLACEMENT FRONT CAMERA(FSC) FIX. MY CAR DOES HAVE THE 'NEW' CAMERA BUT IS OBVIOUSLY NOT FUNCTIONING PROPERLY.
