NHTSA Complaint #11554529 — 2020 MAZDA CX-5

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).
