Tesla Model 3 phantom braking problems

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.

Driving on a 2 lane road going 65 with Traffic-Aware Cruise Control enabled at 65 MPH with a car behind and no car in front of us. the car phantom braked for no reason going from 65 to 40 mph in a matter of seconds. Luckily we were able to accelerate to avoid being rear ended

The vehicle is experiencing severe, unpredictable software and hardware regressions related to the Full Self-Driving (Supervised) system (v14.3.7, Software build 2026.21.5) that create an immediate, active traffic hazard and a high risk of rear-end collisions. Primary Safety Issues: 1. TRAFFIC STALLS UPON DISENGAGEMENT: When Full Self-Driving (FSD) is engaged, auxiliary sensors malfunction, causing the headlights to cycle on/off and windshield wipers to run at full speed in clear, dry, midday daylight. When attempting to manually disengage FSD to correct these malfunctioning systems, the vehicle fails to smoothly transition control. Instead, it triggers critical red flashing alert lights, sounds severe warning chimes, and initiates an immediate, aggressive brake application—stopping the vehicle dead in active, live traffic. 2. PHANTOM BRAKING: The vehicle routinely experiences sudden, severe, and unprovoked phantom braking events while driving at speed, without any forward obstacles or environmental hazards present. 3. STEERING INSTABILITY: When navigating parking lot entrances, the vehicle exhibits extreme "indecisive behavior," resulting in violent, rapid shaking of the steering wheel before completing the maneuver. Tesla customer service was formally notified of these dangerous system behaviors on August 14, 2026. A formal remote engineering log review has been requested from the manufacturer, as these sudden braking actions in active traffic pose an immediate threat to public safety.

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.

The horn on the steering wheel rarely works UNLESS it is pressed directly in the middle. I have tried to honk the horn when there is a safety event but it rarely works. This is definitely a safety issue. This has been going on since I bought the car June 2022. Full self drive is also unsafe and it will make sudden turns, accelerate too quickly, or have phantom braking. This can be unsafe for other drivers. I heard that this is improved with newer models, but if it is unsafe for older models like my 2022, it should not be available.

I getting the Tesla phantom braking almost every week.

COMPLAINT SUMMARY: CRITICAL SAFETY REGRESSIONS IN TESLA FSD SOFTWAREI am filing a formal safety complaint regarding severe, high-risk behavior regressions introduced across the last three consecutive builds of Tesla’s Full Self-Driving (Supervised) software. These defects create immediate collision hazards, cause major route disruptions, and require frequent, urgent driver intervention to prevent accidents.1. INTERSECTION AND TRAFFIC CONTROL VIOLATIONSRed Light Violations: The vehicle correctly identifies a red traffic light and comes to a full stop. However, after a brief pause, the software erroneously treats the steady red light like a stop sign and attempts to accelerate directly into active cross-traffic.Green Arrow Dead-Stops: When approaching a dedicated turn lane with an active, protected green turn arrow, the vehicle frequently applies aggressive braking and comes to a complete stop, creating an immediate rear-end collision hazard for drivers behind me.Phantom Braking: The vehicle aggressively brakes without warning for empty crosswalks, shadows, or distant roadside elements.2. ILLEGAL LANE NAVIGATION AND ROUTING ERRORSErroneous Turn Lane Diving: The vehicle frequently dives into dedicated left or right turn lanes even when the navigation route explicitly commands the vehicle to continue straight. This behavior forces improper turns, requiring backtracking and causing significant destination delays.Incorrect Lane Turning: The system regularly misses dedicated turn lanes entirely. It then attempts to execute sharp left or right turns directly from middle lanes or straight-only lanes, cutting off adjacent vehicles.Turn Signal Failures: The software initiates a turn signal to merge but then cancels the action, or conversely, attempts to execute a physical turn blindly after disabling the turn signal.3. RESTRICTED SPACE TARGETINGHandicap Parking Violations: Upon arriving at destinations, the automated parking software fails to recognize painted stencils and act

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.

When using cruise control, there has been 4 times that the car has engaged in “phantom braking”. We were driving on highways going the posted speed limit of 70 mph, when the car suddenly slammed on the brakes and decelerated to less than 30 mph – all four times we were thankfully not being closely followed by another vehicle or we would’ve had a devastating crash. One time when we looked at the screen, it showed the outline of a person in the median but there was no person/ other obstacle at all. We have reported this to the Tesla service center and they said it is a known issue, and what we have to do is just click the scroll bar and report it so that the engineers can mark the timestamp and collect data so that some patches can be sent over the air/ uploaded at a future date. Nothing has been done to fix the issue and we feel dismissed about our concerns about our family’s safety, and the safety of drivers around us.
