Owners report recurring issues with the automatic braking system in the 2019 Mazda 5, with multiple instances of the vehicle unexpectedly braking or coming to a stop without warning. Complaints frequently mention dashboard warnings such as "Brake System Malfunction" and "Smart Brake System Malfunction," often accompanied by the vehicle shaking or losing acceleration. These incidents occur at various speeds and locations, including highways and city roads, and sometimes lead to near-collisions or actual crashes. Several owners describe these problems arising shortly after acquiring the vehicle, with one reporting the issue within a day of purchase. The described malfunctions pose significant safety risks, including potential rear-end collisions due to sudden stops.

Owners of the 2019 Mazda CX-5 frequently report issues with vehicle speed control, particularly involving unexpected deceleration. Several complaints describe sudden braking or loss of acceleration while using the radar cruise control, often when attempting to pass or merge with traffic, with speeds dropping significantly, sometimes to as low as 20 mph. These incidents occur at various mileages, with some reports around 17,000 miles. A few owners mention the car accelerating on its own from a stop or revving excessively when idling. Safety concerns arise as these issues can happen in traffic, potentially leading to hazardous situations, though no crashes or injuries are reported in the complaints.
