NHTSA Complaint #11444508 — 2021 TESLA MODEL Y

When cruise control or Autopilot systems are active, the car will often slam on the brakes and sound an alarm as if there going to be an imminent collision, even thought the lane is clear in front of the car. This happens most likely often when cresting small hills or on curves. There may be a car in coming in the opposing lane, but there is no danger as the opposing car is fully in their lane. The adapative cruise control or Autopilot system decreases the speed very quickly, often reducing the speed by 10-20mph within seconds. This causes panic for the driver and any cars behind us have to suddenly slam on their brakes, creating a dangerous situation. I own both a 2021 Tesla Model Y and a 2021 Model 3 that both have the Tesla Vision Camera based cruise/Autopilot/collision detection system. This problem has gotten worse as Tesla has released new firmware updates in recent months. Many Tesla owners are reporting that they are having the same issues recently. Tesla's response is that the systems are under development and that they will improve over time. The problem is that this is a safety issue NOW! They seem to be overly focused on developing and testing their full self driving systems that they are ignoring a huge safety flaw in their current cruise control and Autopilot systems.
