Consumer Description

I own a 2021 Tesla Model Y. I took possession of it on August 7, 2021, in Santa Barbara, CA. Ever since, I have had more than 1000 instances of automatic emergency braking (phantom braking) episodes while using cruise control or autopilot. ​The experiences of severe phantom braking have been terrifying. The car often slams on its brakes for no apparent reasons on all highways and freeways, mostly where no cars or obstacles are present. I worry about getting rear-ended, which could lead to injury or death. My Tesla has been in for repair five times, and the technicians say they cannot fix it, that only a software update can solve the phantom braking problem They've been promising a software update since August 2021. After 16 months and five service appointments, I expect the problem would be solved by now. It hasn't. Please force Tesla to remedy this very hazardous safety problem. Let me know what you are doing to force Tesla to fix the problem.
