Consumer Description

When travelling with adaptive speed control enabled the car will suddenly and violently decelerate 30 to 50 MPH below the set speed. This happens frequently and does not appear to correlate with anything specific. Sometimes it happens when passing a large white truck. Sometimes there is no other traffic anywhere near me. At the very least I would like Tesla to give me the option of disabling the "safety" features so the car operates like every other car with adaptive cruse control. This is not just me. Search the internet for Tesla phantom braking and you will find many instances going back years. It seems to be getting worse with each software update.
