NHTSA Complaint #11446758 — 2022 TESLA MODEL 3

Traffic-aware cruise control unexpectedly decelerated and/or activated collision warnings and automatic braking approximately 20 times during a 300 mile, 5 hour drive. All incidents occurred on undivided highways and state roads. This unexpected braking reduces speed by 10 to 30 miles per hour on 60 mile per hour roads. This braking issue greatly increases risk of accident, specifically if another vehicle was following too closely. Braking events occur sporadically, usually attributed to large vehicles driving well within the opposite lane. Some events happened for no reason. Occurrence of unexpected braking is higher at night. This vehicle has been inspected by Tesla in the past due to this same issue and the cruise control and autopilot system was confirmed by technicians to by working properly. The ability to disable adaptive cruise control to standard “dumb” cruise control may solve this issue. This issue instills no confidence in Tesla’s so-called “full self-driving computer” and has me avoiding using these features for my safety, as well as other drivers’ safety. This vehicle is available for inspection upon request. Dashcam video is available on request.
