NHTSA Complaint #11608284 — 2023 TESLA MODEL Y

While driving straight on a 2 lane divided highway, the Traffic Assisted Cruise Control decided it needed to slow itself down significantly to 15 MPH under the speed limit (posted speed limit was 65 MPH). There were no vehicles in front, behind, or beside my vehicle. The breaking occurred when it came across a line break where cars from the opposite side of track could turn left onto a service highway but no one was in that divide nor in the turn lane. There was no warning or any obvious indication that the vehicle should harshly slow down for any safety reason, where in fact is there was a vehicle behind me, it could cause a crash. I made a request for Tesla to repair the vehicle, but in my attached photos, you can see that they admit to the issue being software related and insisting that it is an unrepairable problem until a software update can be issued.
