When using Tesla's Full Self Driving (supervised) speed control is erratic and not subject to the driver's control, such as it would be when using adaptive cruise control. As a result, the available speed modes (sloth, chill, standard, hurry and Mad Max) can cause the vehicle to dangerously exceed speed limits and at times to drive well below the posted speed limit, causing confusion and frustration to following drivers. There is no reason why the software cannot be changed to a safer method that would permit the driver to select the speed at which the car will travel, i.e. the speed limit, similar to adaptive cruise control found in most modern vehicles. When the operator of a vehicle is not in charge of the vehicle's speed, this is inherently dangerous.

After a recent Tesla software update, a mandatory Full Self-Driving disengagement feedback window appears every time I disengage FSD while the vehicle is still moving. The feedback window covers a large portion of the display with a black overlay, noticeable enough something popped up. There is no setting to disable it, dismiss it immediately, or postpone the response until the vehicle is stopped. I am required to select a disengagement reason before I can access the controls and information behind the overlay. While this window is displayed, I cannot properly view or control functions such as music and other touchscreen features behind the area. This is especially dangerous because it appears immediately after I take manual control from FSD—a moment when my full attention should be on the road and the vehicle. The system effectively requires me to look away from the road and interact with the touchscreen before I can make another needed adjustment. This occurs every time I disengage FSD and is consistently reproducible. This behavior began after software version FSD v14.3.3. My vehicle is a 2026 Model 3. The problem occurred everytime while traveling at any speed. I believe this mandatory, non-dismissible overlay creates a serious driver-distraction hazard by obstructing the center display and requiring touchscreen interaction while the vehicle is in motion. Tesla should allow the feedback request to be dismissed, delayed until the vehicle is parked, or disabled entirely.

My Tesla was operating under FSD at 9pm on a dark country road. I was traveling at 45mph and vehicle randomly applied hard emergency braking and I had to take over. It appeared that the vehicle may have been responding to a dark oil stain or possibly a mailbox. Had another vehicle been closely behind me, there would’ve been a collision.

“The affected system was Tesla Full Self-Driving (FSD) (Supervised). FSD correctly selected the northbound left-turn lane but, while executing the left turn to westbound Pecan Street, intermittently directed the vehicle into the eastbound lanes carrying opposing traffic.”

I was involved in a rear-end collision while stopped at an intersection. The impact was significant. During the crash, the front airbags did not deploy. More importantly, the seat belts in both front seats (driver and front passenger) failed to function as expected. Instead of tightening during impact, the seat belts appeared to loosen, allowing excessive forward movement of the occupants. As a result, I was thrown forward and struck the steering wheel. The lack of seat belt pretensioning raises serious concerns about a potential failure of the vehicle’s restraint system. This incident suggests that the seat belt pretensioners and/or related crash detection systems may not have activated properly under a significant collision event. I am concerned that this represents a safety defect that could increase the risk of injury in a crash. I request that this incident be investigated as a possible failure of the restraint system, including seat belt pretensioners and crash sensing mechanisms.

While the vehicle was parked outdoors and the powered rear trunk lid was fully open, I leaned/bent forward into the trunk to retrieve an item. The edge of the trunk lid near the taillight assembly made contact with my scalp, causing a laceration. The wound bled significantly。The trunk lid’s fully-open position, combined with the geometry/edge of the liftgate near the taillight, creates a head-strike hazard for an average-height adult bending into the cargo area. I am requesting that NHTSA investigate whether the powered trunk lid’s open-position geometry presents an unreasonable risk of head injury to vehicle occupants/owners during normal use.

The horn system on the new Tesla are not effective. Other drivers cannot hear The unit is facing the ground, and a high speed. Other drivers. Can I hear it specially when it’s raining.
