NHTSA Complaint #11467378 — 2021 TESLA MODEL Y

We are experiencing two issues with our Tesla Y, one of which I have come to learn is common. That issue is the cruise control will suddenly "disengage" forcing the brakes on, either actively or just through the regenerative components. This has happened in several conditions from high speeds on interstates (>55 MPH) and on smaller state highways (<55MPH). The primary concern is being rear ended by cars following; effectively the Tesla is "brake checking". I am not aware of Tesla pushing updates or addressing this issue in any typeof inspection. There are no warnings, and I have noticed no pattern as to why it happens (and it happens frequently). I have notified Tesla of the issue. The second issue is that the control/infotainment screen has frozen and gone blank on at least four occasions. This as well has happened in various conditions, most recently on both legs of a long roadtrip on the highway. It effectively leaves all control of the car other than steering and velocity out of our control. It is scary. There are no warnings and I am not aware of Tesla doing anything to address the issue though I am aware that it is happening to other vehicles.
