NHTSA Complaint #11473864 — 2021 TESLA MODEL Y

On a roadtrip between California and Wyoming, the adaptive cruise control, full-self driving, and emergency breaking engaged for absolutely no reason on dozens of occasions - what I understand is termed "phantom breaking." This was so bad that on Sunday, July 10, I noted each severe incident. Some of these occurred with absolutely no traffic in the road, some during busier periods. In each case, it was scary and dangers -- to the point where my dog went flying off the seat. While this was an issue throughout the road trip, I only noted incidents on July 10, but please be aware this happened on many other days as well. Here are the significant incidents on July 10. Please note there were less severe incidents on this day that I didn't note because it would have been too many to count. 12pm mountain time just outside Idaho Falls, ID -- car braked with no warning from 70 MPH to 60 MPH 2pm mountain time - 77 miles outside twin falls, ID 256pm mountain time - right outside twin falls 408pm mountain time - heading south from Twin falls towards Nevada -- the car braked three times in rapid succession 447pm mountain time - heading south past Jackpot NV 450pm Mountain time - same 420pm Pacific time - 16 miles north of Wells NV, braking multiple times in succession 524pm pacific time - just west of Wells, NV, sudden braking from 85 mph to 65 mph 643pm pacific time - half way between Wells, NV and Winnemucca NV
