On July 11 at approximately 6:47 a.m., I was operating my Tesla Model 3 on Interstate 65 in Hart County, Kentucky, with Full Self-Driving (FSD) engaged during normal highway travel. Approximately one hour earlier, I had departed a highway rest area after sleeping from the previous day’s travel. Rain developed during the trip, but I observed adequate visibility, apparent roadway traction, and I was not impaired. I was traveling in the far-right lane of a three-lane interstate. The posted speed limit was approximately 70 mph; however, FSD limited the vehicle to approximately 65 mph and displayed warnings indicating that the higher speed was unavailable. While FSD remained engaged, the system initiated a lane change from the far-right lane into the center lane. After entering the center lane, the vehicle began displaying repeated warning messages and FSD disengaged multiple times. I attempted to locate settings related to the warnings on the touchscreen but could not identify an available adjustment. During the third disengagement, I perceived that the vehicle continued braking without releasing while steering resistance increased significantly. The steering wheel then rotated abruptly, and I was unable to regain normal directional control before the vehicle departed its intended travel path and struck a concrete median. The collision caused personal injuries and substantial vehicle damage. I have not been able to reproduce the condition. The incident was investigated by the Kentucky State Police. Based on the sequence of repeated FSD warnings, disengagements, continued braking, and abrupt steering behavior, I believe this event warrants investigation. I request that the federal safety agency review the vehicle’s Full Self-Driving logs, telemetry, Event Data Recorder (EDR) data, steering and braking commands, diagnostic records, and software history to determine whether a vehicle or software malfunction contributed to the collision. Almost like someone had control, into the wall -KM

While driving my Tesla Model 3 with self-driving engaged in excellent conditions, the car suddenly braked to a full stop. There was no apparent reason to do so and the driver did nothing. The road ahead was free of traffic, and no obstacles, pedestrians or animals were visible. It was possible to resume driving by turning self-driving off. Tesla forums online show many instances of others reporting similar problems in various Tesla models over several years. A rear end collision will ultimately be the result of this flaw if it hasn’t yet occurred.

Automatic breaking was initiated as I was pulling in a driveway as I got closer to a large trashcan. The braking was aggressive and I now have concerns that it might've given me minor whiplash as it was so sudden. I have pictures of where I parked. I was about 6-8 feet away from the trashcan when the car automatically braked. I've pulled into this spot numerous times and never had this reaction.

This happened on 2/18/2023. After I charged my car at a local supercharging station, I drove on the local roads for about 2 miles when the car started shutting down. I could barely steer, and the computer monitor stated that the brakes were turning off, and other parts, like cameras, were losing functionality. I pulled over into the local park. I was frightened that my car was no longer functional and that I could be in grave danger driving again. I tried to call Tesla but no one answered. I had to go through the app. My dad came and we found a Youtube video that said to walk out of the car to let it restart. Looks like it happened to another owner. We did that and the car started functioning again. Not sure why it did this after a charge. But it happened again 3 mos later when I was on the freeway. Luckily, I knew what to do from prior experience. But I am mindful of this whenever I supercharge my car. I wait after charging to drive. This shouldn't be the case and Tesla should tell people of this issue. I tried to tell Tesla service when I went in for another repair but they ignored my comments.

My car did a Phantom break while I was driving on President George bush Turnpike E at the Dallas North tollway exit . I was taking the exit with in the speed limit of 40 miles per hour and was keeping the distance from the car in front. Suddenly the car did an automatic break and car slow down significantly. I got hit from behind and had damage to the bumper and trunk. Emergency break feature went out and an alert came. It is very concerning that the car stops in the middle of road by itself and being hit from behind. I would like an answer from Tesla. I have the dash cam footage of the accident

I took delivery of this Tesla Model 3 last month and have been using it often for my commute. Tesla’s “Traffic Aware Cruise Control” is dangerous and has put my life at risk multiple times now when driving on the highway at night. It slams on the brakes as if it is about to crash when nothing is ahead. It also slammed the brakes when passing a semi truck that was accelerating from being stopped on the shoulder. If anyone was behind me, they would have crashed into me. This “phantom braking” only happens at night. I would disable it immediately but it is not able to be disabled! This is the most frustrating part. I have a long commute on the interstate at night and really need cruise control, and now I am constantly worried when commuting that the car will slam the brakes. The fact that I can’t revert to an old fashioned cruise control with no sensors and no cameras is absurd and extremely dangerous. What component or system failed or malfunctioned, and is it available for inspection upon request? I don’t believe anything “failed”. I believe Tesla’s software is not ready for the real world and this “traffic aware cruise control” should be a beta feature that drivers can use at their own risk. How was your safety or the safety of others put at risk? Unexpected, random slamming of the brakes at highway specs on the interstate at night. In all situations that the “phantom braking” has happened, I would have been rear ended if someone was following behind me. Has the problem been reproduced or confirmed by a dealer or independent service center? No Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? No, as there has been no crash yet Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No warnings, no messages, nothing. Just sudden braking when using “traffic aware cruise control”.

Braking and Stopping - Braking system - Improperly functioning braking systems. I experienced a problem with the brake pedal, brake calipers, and/or any component of a Model 3 braking system. “Model 3 has an anti-lock braking system (ABS) that prevents the wheels from locking when you apply maximum brake pressure. This improves steering control during heavy braking in most road conditions…Forward Collision Warning and Automatic Emergency Braking do not operate when driving at very low speeds (see Collision Avoidance Assist on page 128). Do not rely on these features to warn you, or to prevent or reduce-the impact of a collision. (Tesla owners Manuel71-73) I stop on a downward slope with my foot on the brake to wait for a gate to open in my apartments. I let go of the brake and the vehicle remained steady until it started rolling. When it started rolling, I jam my foot on the brake but the brake is engaged (locked). The vehicle accelerates, the brakes and steering wheel is locked giving no control over the vehicle. The vehicle drives through the gate and into a wall. The airbags deploy and I get out immediately for caution of explosion and shock. I call a tow truck and made a claim with USAA. I got a concussion and multiple injuries on my body. I’ve been getting medical treatment for 6-8 months. USAA didn’t help as they deemed the accident was my fault and totaled the vehicle. I bought the vehicle for more than what’s it’s worth. I have loan payment that I can NOT pay. This was my only asset and this accident changed my work life. Tesla gave me the run around on how to make a claim and no compensation. Directed me to insurance company. This demonstrates failure of an Braking System, operating electric vehicles, company responsibility, safety and transportation regulations and policies. These vehicles are highly dangerous for my safety and others as there’ve been multiple accidents and deaths.

While operating TACC with lane keeping assist, I experienced multiple iterations of phantom braking when the road and weather was clear ahead. This phantom braking could potentially cause other drivers to collide with the vehicle that unexpectedly braked in the middle of the highway. This problem has been a common issue with multiple people taking their cars to the service center to get checked out with no problem identified. There are no warning lights or indicators that the Tesla is going to phantom brake on the highway. Recommend having Tesla provide information regarding this phantom braking.
