NHTSA Complaint #11439876 — 2021 TESLA MODEL Y

Our 2021 Model Y features the new vision based cruise control system, both traffic aware cruise control and autopilot utilize this camera only system. At the time of ordering we were under the impression we were getting a much safer and mature radar based system. Upon accepting delivery at the end of May we have accumulated 9,000 miles on the car and have a had horrible experiences with the traffic aware cruise control slamming on the brakes for no apparent reason with nothing ahead or passing cars. Behavior can be 5-10mph slowdowns or in some cases FULL brake pressure which puts us in danger of being rear ended. Multiple times we have been close to rear ended. In addition the system can also produce audible beeps when cars pass however no warning or message is displayed. I want to stress this behavior is a daily occurrence day or night. We have reached out to Tesla in order to get the vehicle looked at for repairs and have a been denied even a service appointment. The vehicle was declared fine hardware wise. I documented our experiences in just one evening of driving and put together this YouTube video showing the behavior. https://www.youtube.com/watch?v=20ETPyzjc_U As referenced in the video below Tesla explains the cruise control is BETA and to be ready to take over at any moment. I take great exception to the practice Tesla is utilizing of declaring previously standard features "BETA" and making customers deal with their poor results with no accountability. We don't accept BETA seatbelts or BETA tires. This feature was enabled by default on the car upon purchase and it objectively doesn't work safely. This compliant is really an act of desperation as we simply have no other avenue to express our frustration and safety concerns for a half baked feature.
