Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“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.”
NHTSA complaint #11384444, filed 2020-12, 8,400 miles“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. …”
NHTSA complaint #11383002, filed 2020-12, 120,000 miles“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”
NHTSA complaint #11421785, filed 2021-06“Mazda dealer is refusing to update software per sspc5 to correct a safety issue relating to the mrcc (Mazda radar cruise control) unless I first agree to having Mazda connected services installed on my 2019 Mazda 3 sedan (csp06). When I purchased my new car Mazda connected services was not included in my car. I am now being coerced into having Mazda connected services installed into my vehicle before they will correct a safety issue regarding a known issue with the adaptive cruise control. …”
NHTSA complaint #11414279, filed 2021-04“The contact owns a 2019 Mazda 3. The contact stated that the vehicle failed to immediately accelerate after the brake assist was engaged.

The vehicle was not taken to a dealer or independent mechanic for diagnostic testing or repairs. The manufacturer was not made aware of the failure. The failure mileage was 7,000.”
