NHTSA Complaint #11541451 — 2020 TESLA MODEL S

From Aug 23 to 28, 2023, we traveled in our 2020 Tesla Model S Long Range Plus vehicle from Santa Fe, NM to San Diego, CA and back, for a total distance of approximate 2100 miles. We drove primarily interstates (I-25, I-10, I-8, I-5) where speed limits ranged from 55 to 75. We experienced numerous instances of what is known to Tesla owners as sudden, severe "phantom braking" [hereinafter PB] while the cruise control was activated (not AutoPilot, nor FSD, just cruise control). In ALL instances, no cars or other objects were visible within 1 mile ahead of our vehicle, and in ALL instances, these "phantom braking" incidents happened on absolutely flat, straight, smooth road surfaces, at all times of day, morning, noon, and night. This car has had PB problems since the day was purchased; in fact on that day, there were at least two sudden PB incidents while I drove home in the new car! At numerous times since, I've reported these problems to Tesla Service---to no avail. The problem is widely known among Tesla owners, and to my knowledge no owner has been able to get Tesla to do anything. On this most recent long-distance trip, our PB incidents happened typically at the posted speed limit of 75mph in all-clear situations---nobody else anywhere remotely nearby. The car would be operating smoothly when all of a sudden the brakes would engage and the vehicle would rapidly decelerate, throwing forward anything not fastened down inside the car. Because of the history of this problem, I NEVER activate cruise control whenever ANY vehicle is near the rear of the car, as I can never tell if my car will "phantom brake" at that moment, causing a possible accident. I consider this problem VERY dangerous. I have owned this car since 2020, and Tesla has refused to do anything to fix it, always coming up with one or other stalling technique or excuse. I consider this an extreme safety flaw of this car and hope NHTSA can help to force Tesla to fix it once and for all.
