Consumer Description

While on our first road trip in this vehicle, we engaged Adaptive Cruise Control (ACC). After about 30 minutes, the vehicle suddenly (within 1-2 seconds), and without warning, decelerated from 75 mph to under 50 mph. After re-engaging ACC, exactly the same thing happened again 5 minutes or so later. Thereafter, we did not use ACC, and the car ran fine. This was a safety hazard because if someone had been following us when these incidents happened, it could have resulted in a rear-end collision. We have not yet taken our vehicle to a service center. Since there was no resulting accident, we have not reported this to any authority. Clearly, however, our Tesla Model 3 has a safety problem.
