Assist problems of the 2025 Tesla Model Y

I am filing a safety complaint regarding Tesla's removal of driver-controlled maximum speed in fsd (supervised), a change that has alarmed a significant number of Tesla owners and safety-conscious drivers. Previous software allowed drivers to set a precise maximum speed via the steering wheel scroll wheel while fsd (supervised) was active. Tesla replaced this with fixed "speed profiles" (sloth, chill, standard, hurry, mad max), none of which allow a driver to set a specific speed. Each profile operates at a programmed range relative to the posted speed limit. Even the slowest profile (sloth) has been observed exceeding the speed limit. The system also frequently misreads posted limits entirely. This is a serious safety regression. In winter conditions, a cautious driver may need to travel well below the speed limit due to snow or black ice. Previously, they could reduce fsd's max speed precisely. That is no longer possible, the system determines speed, and the driver cannot override it downward while fsd remains engaged. This concern is not isolated to just me. Online forums and Tesla owner communities have seen widespread discussion and frustration over this change, with many drivers expressing that it has made them feel unsafe and less in control of their own vehicle. Removing precise speed control from a supervised autonomous system directly contradicts Tesla's stated position that the driver remains responsible for safe operation. This is an ongoing issue and not limited to a single date for the "tell us the approximate date this incident occurred. " I request NHTSA: 1. Investigate Tesla's removal of driver-adjustable maximum speed in fsd (supervised); 2. Evaluate compliance with fmvss and driver control guidelines for automated driving features; 3. Require Tesla to restore precise, driver-controlled maximum speed settings.

On January 28, 2026, the vehicle (a Tesla Model Y) was operating with the full self-driving (fsd) system actively engaged in normal highway traffic conditions. Without any prior warning messages, chimes, or system alerts, the fsd system abruptly disengaged approximately 1 second before the vehicle steered into a concrete road divider. Component failed: the Tesla full self-driving (fsd) software and underlying perception/control systems failed to maintain the lane and abruptly handed over control with insufficient time to react. The vehicle and its data are available for inspection. Safety risk: the sudden, sub-second disengagement provided the driver with zero time to react, take manual control, or perform an evasive maneuver. This system failure directly resulted in a high-speed collision with a road divider, causing significant vehicle damage and physical injuries to the driver that required medical treatment. Inspection/confirmation: the vehicle is currently subject to an open insurance claim and has been evaluated for repair. Warnings: there were no warning lamps, messages, or requests for the driver to take over prior to the immediate 1-second window before the crash. Evidence: I have downloaded and preserved the complete event data record (edr) and the multi-angle dashcam video files. The edr data mathematically documents the sub-second disengagement, and the video files confirm normal traffic flow with no external hazards forcing the collision. I can provide the edr pdf and video files to NHTSA investigators immediately upon request.

While driving westbound on lee jackson memorial highway (u. S. Route 50) after passing the intersection with stonecroft boulevard in chantilly, virginia, the autopilot system on my Tesla Model Y malfunctioned. Without any warning or obstacle in my lane, the vehicle suddenly and sharply veered to the right, directly toward two vehicles traveling in the adjacent lane. I was holding the steering wheel at the time and was able to immediately countersteer to prevent a collision. There were no audible or visual warnings from the vehicle before or during the incident. The autopilot system did not display any messages or alerts, and no braking or turn signal was engaged by the system. The lane shift was abrupt and uncommanded. The dashcam footage clearly captured the incident, and it is available for inspection upon request. To my knowledge, the issue has not yet been reproduced or inspected by the manufacturer or service center. The vehicle has not been examined by police, insurance representatives, or others at this time. This unexpected maneuver created a serious safety risk for myself and nearby drivers.

Computer system failure causing all cameras to fail, mirrors to stay darkened even in daylight, navigation system not updating, collision and lane departure feature failure. Issues were reported to Tesla and an ap 4 computer replacement were scheduled, however service has been delayed for several weeks ( now 9 Jan 2025). The car does not feel sufficiently safe to drive with the impaired mirror visibility couples with the lack of any cameras or safety features working.
