NHTSA complaint #11453749

Owner complaint summary

My Tesla Model 3 is equipped with standard auto pilot (no full-self driving) and traffic aware cruise control (TACC or otherwise known as adaptive cruise control). While engaged, I experience, on average, per 60-mile trip a minimum of 1 phantom braking event. Note this is not on residential, county or state roads, this is on divided highways. The vehicle will slam on the brakes for no reason and will at times activate the forward collision warning system. It's so bad I've disabled many of the safety systems for fear I will cause an accident. Traffic aware cruise control on a two lane road (this does not steer or lane center the vehicle), is unusable because it constantly brakes for oncoming traffic in other lanes, or aggressively brakes for vehicles turning in front of you, even with plenty of distance to clear. The system will even continue to brake, after the turning vehicle has fully cleared the road. This requires the driver to slam the accelerator to cancel the braking action. When I first purchased the vehicle in February of 2020, there were no issues with Phantom braking. This issue has become worse with over-the-air updates. I canceled my full-self driving subscription because the phantom braking was even worse with that software. Additionally, Tesla uses a driver safety score to determine insurance rates if you are using their branded insurance program. When these phantom braking events occur it sometimes registers as an emergency braking event which deducts from your overall score and can ultimately cause your rates to increase. When I enrolled in FSD, before Tesla would release the software, they required a certain safety score over a week's time. During that time the system falsely reported running red lights, emergency braking events, and aggressive stopping, while only using the regenerative braking system. They system will also flag you for tailgating with auto pilot engaged.
