One problem related to car slowed down on its own has been reported for the 2018 Tesla Model 3. The most recently reported issues are listed below.
Twice in the past two weeks, while on autopilot, the car has decelerated spontaneously and dangerously at the same spot on the freeway. The first time almost caused an accident when the car in back of me had to brake suddenly and swerve. I thought it was a fluke when it happened the first time, but it happened again today. Luckily, no other vehicles were in the immediate vicinity. My car had just passed under a large overpass and was near passing under power lines. I reported this to Tesla via the voice activated 'bug report' feature within seconds of the occurrence.
