NHTSA Complaint #11492497 — 2020 TESLA MODEL 3

Ever since a recent software update was downloaded and installed, my Model 3's incidence of "phantom braking" events while using traffic aware cruise control/autopilot has gone up by a very noticeable degree. It has always been a known issue, however since the redundant safety systems (radar and ultrasonic sensors) on my model year vehicle were disabled by one of the recent updates, phantom breaking events that can possibly CAUSE a collision event or loss of control of the vehicle happens far more frequently. Instead of occurring once every 1000 or so miles, it now occurs two or three times every 250 or so miles, judging from performance on recent cross-state road trips. My car does not use the "Full Self Driving" package that Tesla offers.
