NHTSA Complaint #11689065 — 2017 TESLA MODEL S

Software version 2025.32.3.1. Using Tesla’s auto-steer / enhanced autopilot (not fsd) causes many “phantom braking” events when going through several intersections on my commute. It’ll say a message “Curve Assist Active”, however I’ll be on a very straight and flat road with no curves. It’s 65 mph road and it will brake / slow down the car very hard and fast, if I don’t catch it in time it’ll get down to ~45 mph within a second. Even when traffic is going slow already, like 40 mph, it’ll still bring up the message and try to brake and slow down, though not as hard. Typically to about 25-30 mph. I usually can catch it and use the accelerator to prevent it, but sometimes it’ll happen so sudden and I worry about getting rear-ended by someone behind me. Very repeatable. Very startling and concerning when it happens when I don’t expect it to. I believe it’s a mapping issue as it has not been fixed in over a year and after several software updates.
