Consumer Description

Have a recurring issue with phantom braking, without apparent issue, causing the car to suddenly brake (hard) without warning. (60 mph to 30 mph). This happens when using adaptive cruise control. Dealer has been contacted and their response is that this is perfectly normal, it happens to everyone, and that the car and systems are in beta. They indicate all that mechanical components are in working order and my software is up to date. Over time this may be fixed. Meanwhile, I’m concerned about being rear ended caused by my car's sudden phantom braking. This issue is prevalent in other Teslas and reports on the internet are numerous.
