2023 Tesla Model 3: brakes engage by themselves (phantom braking)

Filed Aug 27, 2026 · Acceleration, Brakes · GA

On XXX at around 3:30 PM EST, I was driving my 2023 Tesla Model 3 on [XXX] about 10 miles outside of [XXX]. I had the adaptive cruise control set at 75 mph. I was driving in the right lane of the two available lanes of travel in that direction. I noticed an unattended car on the right shoulder about a 1/4 mile up the road and continued my drive as normal. The car was at least 5' to 6' off the highway. As i got about 30 yards from the car, my car suddenly slammed on the brakes automatically, which forced me to react in a corrective manner. Thankfully there was nobody behind me or the severity of the braking would have likely caused a rear end collision. To my understanding, this phantom braking is a known issue with Teslas, so I wanted to document my experience to add to the record.

Two separate incidents occurred on July 10th and July 12th 2026 involving adaptive cruise control. While adaptive cruise control was engaged my car slammed on the brakes for no reason. There was nothing in the roadway to cause abrupt braking. The second time it occurred my car was close to being rear ended by a vehicle driving behind me. I took the car which is still under warranty to Tesla who confirmed there is a known firmware issue. No time frame was provided as to when the issue will be fixed.

My 2023 Tesla Model 3 (VIN [XXX]) has a recurring safety defect in its driver-assistance system involving two unsafe behaviors. First, “phantom braking”: while driving with Autopilot/FSD engaged, the vehicle decelerates suddenly and without warning when there is no obstacle or threat in its path, creating a rear-end collision risk. This was first reported within the vehicle’s warranty period and has recurred. Second, on the most recent occurrence, with a Tesla service technician riding along to witness the issue, Full Self Driving (Supervised) failed to proceed safely through the intersection of [XXX] and [XXX]. The vehicle stopped mid-turn while another vehicle approached from the opposite direction. I had to take manual control to complete the turn and avoid a hazard. The Tesla technician witnessed this directly, and the service summary states FSD “did not proceed through the intersection properly.” The vehicle has been to a Tesla service center twice for this defect. It has not been resolved. The behavior occurs without warning and is unpredictable. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The vehicle was purchased pre-owned directly from Tesla. On the day of pickup and five days later, while operating on Full Self-Driving (FSD), the vehicle phantom-braked abruptly and then dangerously accelerated through a solid red light into cross-traffic intersections. The driver had to forcefully override the vehicle to prevent a crash. Tesla Service Center was notified but dismissed the issue, performing only a camera recalibration and charging a fee. Following the service appointment, the red-light running behavior stopped, but the vehicle continues to suffer from aggressive, sudden phantom braking multiple times on every single trip, creating a severe and continuous risk of a rear-end collision on public highways.

While driving my Tesla equipped with Autopilot/Traffic-Aware Cruise Control, I experienced an unexpected and abrupt braking event. A vehicle had entered the center turn lane and had already cleared my lane, posing no obstruction to my path. Despite this, my Tesla suddenly applied the brakes without warning, causing a rapid deceleration that could have led to a rear-end collision had another vehicle been following closely. There were no visible hazards, warning messages, or alerts prior to the braking. The incident occurred in clear daylight conditions on a dry road, and the vehicle in the center turn lane was stationary or turning away from my lane. This appears to be a case of phantom braking, possibly due to misclassification of the adjacent vehicle or overcautious object detection by the vehicle’s Advanced Driver Assistance Systems (ADAS). This issue has occurred more than once in similar scenarios, and I believe it poses a serious safety risk. I have not yet had the issue inspected by Tesla or a service center, but I am submitting this report to raise awareness and request investigation into the reliability of Tesla’s braking logic in these situations.

Description of Problem: While driving under normal highway conditions on July 2, 2025, my Tesla suddenly and violently phantom braked — meaning it rapidly and without cause applied the brakes forcefully. There were no obstacles, vehicles, or hazards present. The sudden deceleration caused a severe flare-up of a recent cervical disc replacement surgery I had undergone. I experienced extreme neck and spinal pain and had to seek emergency medical attention. I am now under medical supervision, on pain medication, and unable to work. I contacted Tesla requesting the logs from the incident and have received no response. I’m deeply concerned about the safety of this vehicle and the lack of accountability for this known and previously investigated issue. I am in the process of retaining legal counsel and intend to pursue this further as a product liability and injury case.

I was traveling at highway speeds on a highway with no vehicles or other obstacles in front of me. I had adaptive cruise control on. Then, the emergency brakes deployed for no reason (so called “phantom braking”), decelerating the car quickly. I turned off adaptive cruise control as fast as I could and nothing bad happened. But the situation was dangerous, as if a car was close behind me it could have rear ended my vehicle.

While using standard cruise control (without autosteer), car sporadically & aggressively brakes for no reason with no obstruction or cars ahead and while at highway speeds. With cars close behind, a serious, life-threatening accident could've occurred. Can not determine how to recreate issue on demand. This is a known issue with Teslas that has not been addressed by Tesla. I have not reported this issue to Tesla.

On [XXX], I was driving my Tesla model 3 from California to my new home in Idaho as part of my move there. During the day, I had 6 or 7 situations where the car would suddenly go into full regenerative braking, or outright apply the brakes for no apparent reason. Most of these events took place of freeways at freeways speeds, or on highways (not freeways) at the local speed limit. Every situation was when I had supervised self drive or traffic aware cruise control enabled. These situations were extremely startling and in my opinion potentially dangerous. I don't want to imagine what might have happened if one of these "phantom braking" events had occurred with a heavy 18 wheeler behind me in traffic.

When using cruise control, my 2023 Tesla Model 3 will aggressively brake without warning or apparent cause. The braking is near maximal - as though the vehicle is attempting to prevent an imminent collision. This defect poses a hazard to occupants of vehicles behind mine as well as myself and my passengers as sudden braking could cause a rear-end collision and cascading loss of control. Inclement weather would have exacerbated the problem. This problem is documented. From my brief research it appears Phantom Braking has been the subject of a the federal safety agency investigation previously but for prior model years. The issue persists. When I questioned Tesla Service regarding this life and limb threatening problem their staff was aware and well versed at requesting the customer report the issue as though it were a minor software glitch. This is a significantly more serious problem necessitating an appropriate response.

The car phantom brakes constantly (at least every 10 miles) when using cruise control. You will be driving highway speed and the car will slam on the brakes for no reason,, making the cruise control dangerous and unusable

Driving normally down I-5, no other cars nearby and system suddenly phantom brakes. I am lucky no other cars were behind me as it may have well caused an accident. There were no other cars in front of me within at least 1 mile.
