NHTSA Complaint #11591262 — 2023 TESLA MODEL Y

Was traveling along the [XXX] about 5 miles north of the [XXX]. Vehicle was in traffic awareness cruise control when it suddenly applied the brakes. Vehicle did not sound any warnings. Vehicle did not display any warnings. Vehicle made no attempt to warn driver of a braking event. Vehicle traffic awareness cruise control was set to 79 or 78 mph in a 70 mile per hour zone. I was able to push the accelerator pedal to regain speed but had already dropped to about 65 mph. Vehicle did not pass under a shaded section ( I. E. no bridge or trees or big rigs) There was change in color of the road top. My foot was resting just in front of the accelerator pedal. Fortunately for us, there was no vehicles directly behind us. This incident is the 3 of this kind in this vehicle. This has me spooked to use any of the convenience software. I already do not like using the autopilot feature because of it erratic behavior. It feels very unsafe and unpredictable. We are unable to predict when this car will act on its own and feel it will cause us harm one day with actions like this. We are glad that no one was following us closely because they might have hit us. We are also upset that the vehicle never stated why it braked suddenly.
