2026 TESLA MODEL Y Forward Collision Avoidance Automatic Emergency Braking Problems

I am submitting this complaint regarding a newly leased 2026 Tesla Model Y Premium RWD, which I took delivery of on February 6, 2026 from Tesla Watertown, MA. I am a returning Tesla customer and entered this lease after test driving the same model on January 24, which did not exhibit any issues. Immediately upon driving the vehicle off the lot (approximately 12 miles), I noticed a persistent rattling noise from the front suspension area. The noise occurs over normal road conditions and has been present since delivery, significantly affecting the quality and value of the vehicle. On February 9, Tesla Watertown evaluated the vehicle and later replaced both front upper control arm (FUCA) mounts. On February 10, before repairs were completed, multiple safety systems suddenly disabled while driving, including regenerative braking behavior, traction and stability control, lane safety features, and automatic emergency braking, creating a dangerous situation. I returned...

Rear-end collision. My Tesla impacted the rear of another vehicle at approximately 15–18 mph. No forward collision warning observed. Owner-provided data shows AEB status as SNA. Impact is such that the car is totaled.

The vehicle repeatedly [XXX] [XXX], and [XXX] displays critical safety alerts indicating failure of the parking brake and automatic vehicle hold systems. Specific error codes documented include: •DI_a246: Automatic vehicle hold disabled (Use brake pedal when stopping) •EPBL_a179: Parking brake functions degraded (Parking brake may not apply or release) •UI_a019: Parking brake functions degraded INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

On January 20, around 9:35 am, Phoenix time, I had the car in self-driving mode for a left-hand turn at the intercession of Camino Real and River Road in Tucson, Arizona. A real-time view shows that it’s a tricky and dangerous left-hand turn. For the past 3 weeks, the car navigated it well, waiting until it was perfectly safe to do so. Today, however, the car moved quickly and unexpectedly into the center of River Road, narrowly escaping a head on collision with a west-bound car, and then paused, squeezed in between west and east-bound lanes when I tapped the brake and took the wheel. Everything happened so quickly. I made the left turn into the east-bound lane, but, looking back, I don’t know how an accident didn’t occur, as traffic was still moving in east-bound lanes rapidly. There must have been enough distance between two cars at just the...

While driving on a residential street at night with Full Self-Driving (Supervised) engaged, the vehicle suddenly applied Automatic Emergency Braking without any visible obstacle, vehicle, pedestrian, or hazard present. The braking was abrupt and unexpected and did not correspond to traffic, road conditions, or driver input. No collision occurred, but the sudden stop caused a whiplash effect to occupants, creating a risk of injury despite the absence of an external hazard. The driver immediately disengaged the system after the event. Tesla later reviewed vehicle data and confirmed that an Automatic Emergency Braking event occurred while FSD (Supervised) was active. Tesla identified the software version as FSD v14.2.1 and documented the incident as unexpected emergency braking, with the date, time, location, and environmental conditions recorded.

While Full Self-Driving (Supervised) was fully engaged (blue steering wheel icon active), the vehicle approached an uncontrolled intersection, selected the wrong path, hesitated severely (camera shaking violently), provided ZERO visual or audible warnings, and completely ignored driver's emergency brake input (pedal depressed >90% approximately 1.5 seconds before impact). The vehicle continued forward by inertia and collided with a roadside curb, resulting in wheel damage. Attached dashcam video clearly shows: • FSD active throughout the event • No alerts or chimes • Violent steering oscillation/hesitation • Driver's foot slamming brake pedal with no deceleration • Impact despite timely braking This incident matches the ongoing NHTSA investigation PE25-012 regarding FSD intersection hesitation and failure to respond to driver input.

On the day of the incident, I drove my vehicle into the charging station and activated the Tesla FSD autonomous driving and automatic parking functions. During the automatic parking attempt by the vehicle, the system exhibited the following severe loss of control behaviors: 1. The vehicle automatically collided with the vehicle in front without any human operation. 2. It paused for about 1 second after the collision. 3. Then, the vehicle suddenly accelerated in reverse at high speed, again without any driver operation. 4. It directly hit another Tesla that was charging behind my vehicle. The entire process is fully executed automatically by the vehicle system. I cannot intervene or stop the system through the steering wheel or brakes. II. Severe Security Risks When the accident happened, my friend was sitting in the passenger seat. If the vehicle had moved a few more inches, it could have caused serious injury...

When using cruise control (traffic aware cruise control and autosteer) the car acts dangerously and stops for no reason. I've been driving on open roads with no traffic in front of me on regular roads, the car will slam on the brakes and it causes the people behind me to need to slam on their brakes as well. I feel like I'm going to get into an accident constantly... I was on the freeway and no one around in front of me and the car slammed on the brakes to almost a stop on a 70 mph speed limit road. Today the same thing occurred in high traffic on a 55mph road, luckily the driver behind me wasn't to close and was able to stop in time ... There is no option to use regular cruise control or disable enough features to prevent this from occurring... It's incredibly terrifying. If...

TESLA FSD Issues: 1. Phantom braking sudden to a full stop for no known reason in the middle of the road, throwing my dogs into the floor and the car stopped completely on the highway. If an infant had been in the car Ina car seat, their neck could have been broken 2. Sudden jerkiness when making turns 3. In one case the car suddenly changed lanes and was a close encounter. 4. FSD system is now completely non-functioning. 5. These issues started about about 1 month ago and worsened in the past 1 week after the latest software update. TESLA Premium Connectivity Navigation Issue 1. Instead of taking me on main roads to my destination, it has been taking me down rural, isolated dirt roads. In one case I was directed to a dirt, logging road, isolated and dangerous terrain. I had to turn around in a secluded area...

I was using the full self driving feature of the vehicle. At an unusual intersection, there was a flashing do not turn right light because of a train. The car turned right ignoring the do not turn sign And headed for the railroad tracks. I had to slam on the brakes because the car was not going to stop. If a driver is not paying attention they will die. I have video of the whole thing.

I would like to formally report several incidents I have experienced with my newly purchased Tesla Model Y. I acquired the vehicle on [XXX], collected it from Washington D.C., and drove it back to Houston between September 20 and 21. Prior to my return journey, I conducted a test drive. During this drive, at dusk, I engaged Full Self-Driving (FSD) mode. The vehicle stopped appropriately at a traffic light; however, once the light turned green, it moved forward but veered into the yellow safety buffer zone located between the lanes of opposing traffic. I intervened by manually steering the car back into the correct lane. A similar occurrence happened in Washington D.C. while attempting a left turn under a highway overpass—the vehicle again crossed into the yellow lines. These incidents suggest that the FSD system did not reliably detect the yellow lane markers. On the weekend of [XXX], during my...

My Tesla Model Y was in Full Self Driving Mode when it turned into a garbage truck, leading to a total loss to my car. There were no warnings from the Tesla system that could have helped me prevent the crash. Thankfully, no one was hurt, but my car is not longer usable.

What component or system failed or malfunctioned, and is it available for inspection upon request? The Full Self-Driving (FSD) system malfunctioned. While traveling northbound with the flow of traffic in the middle lane of a surface street, the vehicle initiated a sudden right turn onto a freeway on-ramp at excessive speed and without adequate steering input. This resulted in the vehicle colliding with the left-side barrier. The vehicle is currently in the custody of State Farm Insurance and can be made available for inspection upon request. Dashcam footage of the incident has been preserved. How was your safety or the safety of others put at risk? The unexpected maneuver caused the vehicle to lose control and strike the barrier, placing both the driver and other motorists at risk. The driver had no time to react to this unexpected action. The driver sustained a whiplash injury along with left shoulder and...

Yesterday on October 1st I was driving car recently last few days my car usually go more right side but I thought this may be due to keep in lane car feature or something so I didn’t bother much but yesterday when I was driving at around 11:13 am I didn’t know I reciived notifications in car about 1.automatic vehicle hold disabled 2.tracking control disabled 3. Stability control disabled 4.break pedal regenerative breaking unavailable 5.lane departure avoidance feature unavailable 6. Automatic emergency breaking unavailable And I see from y car pe drive vidio recording in 11:14 minute one my car hit curb and it damages my both side wheel and tire so badly damaged and broke like out of both pieces came off but didn’t flat my tire and when this happens I was trying it break but it didn’t break instead in lost all function so it was kind...

Our 2026 Tesla Model Y could not stop at a traffic light and rear ended the vehicle in front of it. Pumping the brake peddle had no effect. The incident did show up in the vehicles app. The front end was damaged (hood, drivers side fender and bumper). I contacted a Tesla representative and was instructed to make an appointment at a collision repair center to have the body work done prior to having the brake system diagnosed. I do not feel safe driving this vehicle at this time. I feel that Tesla should bear the cost for the collision repairs.

I was provided a Tesla Model Y Juniper demo vehicle for a test drive on August 3, 2026 and the incident took place in it around 6:00 pm (±45 min). Full Self-Driving (FSD) was engaged. I had placed an order for a new Model Y on August 2 and took delivery on August 10 (different VIN). During the demo, FSD initially performed well: it autoparked into an apartment parking spot and exited once correctly. However, the second time, the system made a dangerous maneuver. It activated the left indicator and accelerated rapidly as if entering a roadway, but instead turned left directly into a pole. The pole struck the rear door. I braked, but the system’s sudden move left no time to react. A reasonable human would have exited slowly and cautiously, but FSD acted abruptly and unsafely. My pregnant wife was in the passenger seat, and both of us...

24 hour after taking delivery, operating on Full Self Driving on a residential street at 25-30 mph, the car struck a landscaping trailer parked on the right.The tailgate of the trailer was down and the car struck the left rear upright post of the trailer causing significant damage to my car. No automatic breaking occurred: the car struck the trailer at full speed. The collision alarm sounded just as the vehicle struck the trailer, not before. I requested vehicle status info form Tesla, but the video stops well before the collision and I can't decipher the rest. But I can send it to you if it would be helpful,.

I was in a parking lot and activated Autopilot while the car was next to a stationary pillar near a parking space. Immediately after activation, the vehicle failed to detect the pillar and drove directly into it. The impact happened so quickly that there was no practical opportunity for human intervention to avoid the collision. There may or may not have been a warning, but even if a warning was displayed, it occurred too late to allow the driver to react before the impact. The system did not provide effective parking collision warning or apply automatic emergency braking. This incident caused damage to the driver-side door and mirror. My safety and the safety of others were at risk because the system failed to prevent a collision with a fixed obstacle. No inspection has yet been performed by Tesla service.

Vehicle Make/Model/Year: 2026 Tesla Model Y (Launch Series) Incident Date: [XXX] Incident Location: [XXX] System/Component Involved: Automated driving systems / Autopilot / Steering What Happened: While driving my new 2026 Tesla Model Y on Autopilot, the vehicle suddenly turned off the main road near [XXX] , and steered toward the curb. I immediately pressed the brake, but due to the vehicle’s speed, it still hit the curb, causing damage to the front right tire, wheel well liner, and triggering multiple system error messages. Shortly after, I witnessed another Tesla Model 3, also using Autopilot, make the exact same wrong turn at the same location and crash into the curb. No injuries occurred, but this appears to be a mapping or Autopilot software issue that can cause vehicles to leave the roadway unexpectedly, creating a serious safety hazard. Tesla is preparing the incident data, but this report is being filed to...

Phantom braking on the highway. We were the only car and without warning the car slammed on the brakes. There was nothing for the vehicle to hit in the road or cross traffic.It did this 3x in 35 miles. This has happened both while just cruise control and when the full self driving was on. We are too worried to use either of there is any traffic around us. We have not been to dealership yet. Fast beeping when it hits the breaks. Have not seen any alarms.

The incident occurred on [XXX] around [XXX] (from the dashcam footages) in a highway (don't know the place, but I have a police report). I was driving my Tesla model Y 2026 with Full Self-Driving (FSD v13.2.8) Beta engaged when the vehicle suddenly off the road and hit the fence on shoulder. I retrieved dashcam footage from the incident, including footage leading up to and during the accident. the FSD system malfunctioned, the car is in a body shop and is available for inspection upon request if done quickly; Huge risk to myself and others because no way know when the FSD failed; from this link, same issue: [XXX] the vehicle has not inspected by others no any warnings, the fsd had been working properly in the firt 300 miles trip; but all of sudden, swerved to the roadside with full speed.

I was driving my 2026 Tesla Model Y when another vehicle pulled out from a driveway and struck the front/side of my car. The Tesla failed to initiate Automatic Emergency Braking (AEB) and no airbags deployed. This raises serious concerns about the functionality of Tesla’s safety systems in real-world scenarios. The vehicle has not been modified in any way and was in standard driving mode. I have contacted Tesla Support requesting a diagnostic and explanation, but I believe this incident should also be reviewed as a potential safety defect.
