NHTSA Complaint #11500061 — 2019 MAZDA CX-5

My 2019 Mazda CX-5 automatically applied the brakes while the car was on cruise control traveling at 65 mph on a highway, and there wasn't a car or any object in front of me or to either side of my car. The car applied the brakes firmly and brought the speed down quickly and dangerously. I quickly depressed the accelerator to get the car back to highway speed to avoid a rear-end collision. This issue has happened 3 times in the past 2 weeks, all while traveling at highway speeds on cruise control for an extended period of time (hours). I believe this is the same issue with the Mazda Smart City Brake Support system that led to a recall of 2019-2020 Mazda-3 vehicles. My Mazda CX-5 is out of warranty and the dealer stated it is not covered by the recall.
