2020 Mazda CX-5 Brakes Problems

While driving on the highway in traffic, I was applying the brakes (slowly and smoothly) and moving with the flow of traffic when the SBS system activated the brakes harshly and slammed me to a stop without reason. In addition to throwing me forward against my seatbelt, it also resulted in the car behind me rear-ending me. I did not hit the car ahead of me, since I was far enough behind them BEFORE the smart brake support engaged, but the feature caused an accident that could have been avoided.

While driving forward in a straight line during broad daylight at approximately 40mph, the car in front of me slowed and turned right onto a side street. I applied brakes to slow myself (to ~25mph I estimate) until the car in front of me was fully out of my lane. Once the car in front of me was out of my lane, I released the brake in order to accelerate back up to the speed limit, but before I could press the gas pedal the car suddenly slammed on the brakes, beeped warning beeps, and displayed BRAKE on the dash. It did this for less than a second before deactivating. It did not fully stop the car. It just caused a sudden, severe braking event and then the car returned to normal operations. This exact road scenario (car in front turning right onto a side street while traveling at city speeds of ~30-40 mph during daylight) has caused the sudden temporary automatic braking twice, and two other times in this same scenario the BRAKE warning displayed and sounds activated but without automatic braking. These four events occurred within the less than one year that I have owned the car. One of the automatic braking incidents happened in cold temperatures on snowy/icy road conditions. The other occurred in traffic with vehicles following behind my car close enough to risk a rear-end collision. I have reached out to a dealership to request the safety sensors be inspected, but I have seen on internet communities [XXX] and [XXX] ) that many people have encountered this exact behavior (sudden unexpected braking) in the exact same scenarios (car ahead turning right).

On Septmber 2, 2023 the car had been on a 4 hour road trip. I came into the driveway, left the car running in Park with the brakes on (listening to music while I cleaned the car out) it was idylling for about 5 minutes. I went to the drivers side door, which was open and reached in to turn the car off using the start/stop button. Before I could turn the car off, it started backing up and the door ran over me. The car was definitely in Park and the Brake was on. There was no reason for the parking brake to disengage.

My car only has 32000 miles on it and I was told that I need new brakes and calipers. My car is making grinding and creaking noises when I back up, stop or get into it. Because of these brake issues it feels like the car is taking longer to stop. I have never had a car that needed this extensive of a brake job at 32000 miles. This seems excessive.

SUDDEN BRAKING CAUSED BY AUTOMATIC BRAKING SYSTEM. ON SEPT 1, 2020, I WAS DRIVING DOWN A NEIGHBORHOOD STREET, GOING ABOUT 30 MPH, AND A CAR IN FRONT OF ME WAS TURNING. I WAS IN NO DANGER OF HITTING THE CAR IN FRONT OF ME; HOWEVER, MY 2020 MAZDA CX-5 SUDDENLY BRAKED AND MADE A LOUD NOISE. GRANTED, THIS CAR WAS NEW TO ME AND I HADN'T EXPERIENCED THIS BEFORE, BUT I WAS COMPLETELY SURPRISED GIVEN AN ACCIDENT WAS NOT IMMINENT. THIS SUDDEN BRAKING CAUSED MY HEAD TO SWING FORWARD AND BACK RESULTING IN NECK, SHOULDER, AND BACK PAIN. ALSO, IT RESULTED IN AN INCREASED HEADACHE. UPON RETURNING HOME, I TURNED THE SUDDEN BRAKING SAFETY FEATURE OFF. ON SEPT 4, 2020, I HAD A VIDEO CALL WITH MY PCP WHO ADVISED ME TO GO TO THE URGENT CARE. THE URGENT CARE DOCTOR PRESCRIBED MUSCLE RELAXERS AND, BASED ON A PREVIOUS NECK CONDITION, ORDERED A MRI AND FOLLOW-UP WITH NEUROSURGEON. THE EXTENT OF THE INJURY IS UNKNOWN AT THIS TIME BUT THE URGENT CARE DOCTOR ENCOURAGED ME TO FILE A SAFETY REPORT.
