I want to raise a serious safety concern with a recent Tesla software update related to Full Self-Driving (FSD). When I disengage FSD, a prompt immediately appears on the main screen asking why I intervened, with selectable options. Here is the issue: When I take over from FSD, it is almost always because something requires my full attention in that moment. That is the exact point where I need to be focused entirely on driving, not reading or interacting with a screen. Introducing a pop-up at that precise moment creates a distraction during a potentially critical transition from automated to manual control. From a human factors and safety standpoint, this feels backwards: - The highest-risk moment is the handoff from FSD to driver - The system is adding cognitive load and visual distraction at that exact time - Even if interaction is optional, the visual interruption alone pulls attention This is not just an annoyance—it has real potential to increase risk in already sensitive situations.

While traveling on the freeway with Full Self-Driving (Supervised) engaged, my vehicle attempted to initiate an automatic lane change to the left. At that exact moment, another vehicle was already traveling parallel to me, fully established in the adjacent left lane. My vehicle signaled and immediately began veering directly into the occupied lane, completely failing to detect the car traveling next to me. The system did not abort the maneuver or yield to the existing traffic. To prevent an immediate sideswipe collision, I had to forcefully grab the steering wheel and wrench the car back into my original lane. The FSD system completely failed to monitor its immediate left blind spot.

I was pushed to complete an update on my 2023 Tesla Y with an over the air update. This happened last week. Following the update i have been getting a slew of errors when driving my car related to the parking break, brake functions, automatic energy braking and steering are affected. The wording on the app / car says, Alerts - Steering & Braking - Parking brake functions degraded / Parking brake may not apply or release / Parking brake may not apply or release. This causes my auto brake to not engage, my hold break to not engage, my parking brake to not engage. This causes my car to roll at stop / red lights. I have to physically slam by brakes to stop. This is extremely unsafe and Tesla is trying to charge me $130 to diagnose the car to see why the update caused the issue. My car went from fully drivable without any FSD, normal driving to a runaway trainwreck. This happens roughly 20-30 minutes randomly into driving. Not immediately and it is completely random.

On 07/16/2026, I was driving my 2023 Tesla Model Y when the vehicle suddenly began swerving rapidly left and right across multiple lanes without my intended steering input. The vehicle became difficult to control, and despite my attempt to correct the direction, it continued to move unpredictably and resulted in a collision. There were no prior warnings or indications of a steering or control issue before the incident. After the collision, I reviewed the Tesla USB drive and found that Dashcam and Sentry Mode recordings from immediately before and during the incident were not available; only recordings after the incident were present. I am concerned that a possible steering, electronic control, or software malfunction may have contributed to the loss of vehicle control.

We recently got a subscription for Tesla's full self driving (FSD) system. While using the system, on several occasions, the car "jerked" momentarily. Like it is hard braking but then the car resumes its previous pace. Again, this is very quick, perhaps taking less than a second. It is an occasional occurrence, but it has happened enough times that I am not using the feature anymore. For a split second, It feels like the car was stopping abruptly, which startled everyone riding in the car. My wife called Tesla and provided the information above to an automated help center. She was told to try the "Hurry" mode in FSD. We've been using the "Standard" mode.
