What component or system failed or malfunctioned, and is it available for inspection upon request? Emergency Breaking in Autodrive mode. How was your safety or the safety of others put at risk? My car auto breaked hard for no apparent reason when I was driving at 75 MPH on an open highway. Has the problem been reproduced or confirmed by a dealer or independent service center? There are plenty of articles online about Phantom Breaking. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, this happened yesterday morning on 11/18/2023. I plan to report this to Tesla today as well. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Not a single warning and this was the first time that this has happened to my vehicle. I was driving using auto drive at 75 MPH on highway at 8:45AM on 11/18/2023. All of a sudden, and for no reason, my Tesla Model Y slowed down within 3 seconds to around 45 MPH. This was completely unexpected as no other car, debris, person was near me. When I got. home that day, I read about phantom breaking with the Tesla. What happened to my car is yet another example of phantom breaking. This could have caused a major accident if there were more cars on highway at the time. Luckily no one was injured, but my daughter and I were in shock and shooken up.
