2017 TESLA MODEL 3 Vehicle Speed Control Problems

Feb 25 around 4pm PT we were driving north on US Hwy 101 using the basic cruise control feature of our Model 3. Based on our settings I believe this would be considered adaptive cruise control, but I'm not sure. Enhanced Auto-Pilot was not in use. On a largely open highway, in particular with no one in front of us, and thankfully, no one close behind us, the car suddenly started to lose speed, not brake, just lose speed. I pressed the right-hand button on the steering wheel and called out "report bug" so there should be an incident record with Tesla I believe. After letting it slow a bit, I pressed the accelerator to resume and it resumed speed ok. I have used the "report bug" several times on this issue so there should be records of other incidents. Feb. 26, around noon. Traveling on Central Expwy at 55,...

Experiencing unexpected braking on freeway while on cruise control. Car brakes for apparently no reason. There is no warning, vehicles in sight, on clear sunny day. Has braked up to 3 times/hr on two different days on road trip. No indicators say that anything is wrong with the car or its cameras. It is jarring and scary for both driver and passenger. Collecting info for Tesla service appt in August. Read info of phantom braking for newer Teslas. We drove this same route in this car in summer of 2019 and didn’t experience phantom braking.

On August 9th, 2021 I was traveling on Interstate 40, in NC, at MM 103 at approximately 70 mph. when with no warning the Main Control Unit (MCU) went blank. Adaptive Cruise control, speedometer were not operable or could not be seen. The MCU reset after a brief (5 second) pause. I immediately placed a service request for August 25th with Tesla. Tesla updated the firmware and performed standard maintenance on August 25th. See attached screenshots. On October 26th, at approximately 505 in the afternoon, I was traveling on I-40, in NC, at 70 mph when again the MCU went out but did not reset itself and remaind blank for the remainder of my trip, approximately 20 minutes. During this time adaptive cruise control, speedometer, turn signals, wipers and lane assit features were inoperable. I was able to complete my travel that afternoon in the car. On October 28th, I...
