2019 MAZDA MAZDA3 Forward Collision Avoidance Automatic Emergency Braking Problems

To whom it may concern, I was on a back road late in the evening not far from home [XXX] and a small deer ran into the road. I needed to brake to avoid hitting the deer. After breaking, a Brake System Malfunction warning message and i-ACTIVESENSE System Malfunction warning illuminated on my dashboard. I brought the car to a Mazda dealership the next morning. The technician determined that the brake fluid level sensor became stuck, requiring replacement of the brake fluid reservoir and the brake fluid level sensor. What failed: The repairs include replacement of the Brake Fluid Reservoir and the Brake Fluid Level Sensor. This is the link to the dealer report [XXX] . No one other than the dealer has inspected these parts to my knowledge. There was no accident of any kind. I personally felt unsafe after these parts failing and reached out to Mazda Customer...

the vehicle started surging at low soeeds and accelarating and control module issues for the transmission

was driving in a car park and it randomly braked thinking someone was infront of me but there was nothing and the car behind me almost rear ended. Already fixed the recall last year according to Mazda. This is extremely scary and not sure what would have happened if this was on a highway

I WAS ACCELERATING AFTER A TRAFFIC LIGHT TURNED GREEN AND THERE WERE NO CARS IN FRONT OF ME WHEN THE CAR STARTED BRAKING AUTOMATICALLY AND CAME TO A FULL STOP. LUCKILY THE CAR BEHIND ME WAS ABLE TO STOP IN TIME BUT THERE WAS NO WARNING AND NO REASON. I COULD HAVE BEEN REAR ENDED. I PULLED OVER AND CHECKED THE TWO SENSORS AND NEITHER ONE WAS BLOCKED (IT HAD SNOWED HERE RECENTLY). I'M HONESTLY SCARED THIS COULD HAPPEN AGAIN AND MAZDA IS SAYING THERE ARE NO OPEN RECALLS ABOUT THIS FOR MY CAR AND THAT THE CAR IS FINE.

WITHOUT CAUSE: THE VEHICLE WILL SUDDENLY DETECT THE PRESENCE OF ANOTHER VEHICLE AND/OR SENSE AN IMMINENT COLLISION AND SUBSEQUENTLY APPLIES THE AUTOMATIC BRAKING SYSTEM, CAUSING THE VEHICLE SPEED TO SUDDENLY DECREASE. THIS HAS HAPPENED REPEATEDLY OVER THE COURSE OF DRIVING THE CAR AND RESULTED IN BEING ALMOST REAR ENDED NUMEROUS TIMES. THIS IS A VERY DANGEROUS SCENARIO AND COULD EASILY CAUSE A SEVERE ACCIDENT, ESPECIALLY ON THE FREEWAY WHEN EVERYONE AROUND IS GOING REALLY FAST AND NEEDS MORE TIME TO REACT TO THE SUDDEN AND SHARP SLOWING DOWN OF MY VEHICLE. THIS HAPPENS IN VARIOUS LOCATIONS, FREEWAY, HIGHWAY, OR IN THE CITY. I HAVE TAKEN THE CAR TO THE DEALERSHIP NUMEROUS TIMES TO HAVE THIS FIXED, BUT GET A DIFFERENT ANSWER EVERY TIME I TAKE IT IN. BUT THE PROBLEM REMAINS UNRESOLVED AND CONTINUES TO PLACE ME, MY PASSENGERS, OTHER DRIVERS, AND EVEN PEDESTRIANS IN HARMS WAY.
