In owners' own words
Automatic break system malfunctions often and does a hard break. Also the perimeter sensor gets disabled numerous time out of blue while driving and stop functioning until the car restarts. The break happens without any prior indication or same situation. It just happens on the regular road as well as highway. But the highway just scares me. But there is no way I can tell Mazda with a proof. Service brakes · reported at 5,200 miles

The smart brake system is malfunctioning. The car slams on its brakes for no reason. No vehicle is ahead of me. I have been driving at highway speeds when this occurs and I haven't been rear ended yet. It's happened numerous times before and after I completed the recall. The condition is worse when it's raining. The car has been at the dealership for over 30 days unable to repair. Service brakes · reported at 400 miles
