NHTSA Complaint #11546747 — 2023 TESLA MODEL 3

When cruise control is engaged, the vehicle suddenly decelerates, (at times dropping speed by more than 20 mph in less than 2 seconds). This occurs as often as 5-10 times in a single 60mi trip, and occurs at least once per trip on this same route (divided highway, sometimes with hills, often with no other cars ahead of or around the vehicle, speed 60-70mph) These events are unsafe because unexpected braking is a hazard for following cars and my passengers. My job as a driver is to be as predictable as possible, but when I use the cruise control the car behaves unpredictability Problem reported to dealer, confirmed by remote diagnostic, and car was serviced but the problem got worse. There are no warning lamps or error messages displayed in conjunction with these sudden braking events. First appeared when the car reached 2000miles on odometer
