What 411 owners told NHTSA about the 2023 Tesla Model 3

A fatal crash occurred involving a 2023 Tesla Model 3. The vehicle departed the roadway, impacted a guardrail, struck a utility pole on the driver’s side, rolled down an embankment, and came to rest upright. The crash resulted in catastrophic intrusion into the driver’s compartment and a fatal injury to the driver. I am requesting that NHTSA investigate the crashworthiness and occupant protection performance of this vehicle, including the structural integrity of the occupant compartment, airbag deployment and effectiveness, and the performance of any advanced driver assistance systems, including collision warnings and automatic emergency braking. I am also requesting review and preservation of all available vehicle data, including Event Data Recorder (EDR) information, vehicle telemetry, driver assistance system status, warning notifications, braking data, steering data, and any other information recorded before and during the crash. At this time, I do not know whether a vehicle defect or system malfunction occurred. My concern is whether the vehicle’s safety systems and occupant protection systems functioned as intended and whether additional vehicle data may help determine if any safety-related issues contributed to the severity of the crash.

I am reporting a safety concern involving a Tesla operating with Full Self-Driving Supervised active. On June 5, 2026, at approximately 7:50–7:55 AM Pacific Time, the vehicle was being driven with FSD Supervised engaged. The vehicle was in a turning maneuver when the driver mistakenly applied the accelerator. Vehicle data provided by Tesla appears to show ACTIVE_FSD shortly before the incident, a turning/steering angle, accelerator-pedal input/override, FSD becoming unavailable, and then crash-related/braking/tire-pressure signals shortly afterward. I am not claiming the vehicle accelerated on its own. The data appears to show driver accelerator input. My concern is that while FSD Supervised was active and the vehicle was already turning, the system allowed a strong accelerator override that rapidly worsened the situation. In this case, the vehicle went over a curb/sidewalk area and sustained significant damage. The safety concern I am reporting is whether FSD Supervised should better limit, warn, or manage strong accelerator override during low-speed turning maneuvers, especially where the vehicle may leave the roadway, cross a curb, or enter a sidewalk area. I believe this involved driver error as a mistake pedal acceleration, but the system design may have allowed that error to create a more dangerous outcome.

While driving at highway speed under normal operating conditions with the accelerator engaged and no braking input, the vehicle suddenly experienced a sustained 6-minute-12-second ADAS/EDR degradation cascade. This included OVERHEAT_PROTECT_FANONLY activation, repeated AEB_CAN_STATE_UNAVAILABLE toggling, FAULT 14.0 brake-signal mismatch, impossible negative brake pressures, and 27+ ABS/EBD/ESP fault-lamp cycles. No warning lamps, messages, or alerts appeared prior to the cascade. The degradation resulted in loss of braking assist and stability control functions, causing two collision events (right-side T-bone impact followed by curb strike) despite no driver error or input. This failure mode matches the exact ADAS/EDR degradation pattern under active NHTSA Engineering Analysis EA26002. Full technical details, timestamps, fault logs, sampling gaps, and EDR data are provided in the attached narrative PDF and supporting CSV files.

The vehicle’s brakes did not work, automatic emergency brakes and collision warning both did not work. I pressed on the brake for about 5 seconds but the brakes did not work, resulting in a collision with the car in front. Everything is available for inspection if needed. Both my safety and the driver of the vehicle in front of me was at risk. The problem has not been confirmed yet. The vehicle is currently at a shop, waiting inspection. There were no warning lamps, messages, or symptoms.

On [XXX], my 2023 Tesla Model 3 (VIN: [XXX] ) suddenly accelerated on its own and the brakes failed to respond despite repeated pressing. To avoid hitting other vehicles, I turned into a property driveway and struck a tree. The airbags deployed. This was a case of sudden unintended acceleration combined with complete brake failure, creating a serious safety hazard. Forward Collision Warning also did not prevent the impact. A police report was filed by the Dekalb County Police Department, GA, USA (Report #[XXX], Case #[XXX]), which specifically documented brake failure as the cause of the accident. The report also notes that the driver was injured by the airbag and that the vehicle had to be towed from the scene. A copy of the police report can be provided upon request.

The contact rented a 2023 Tesla Model 3. The contact stated that while driving at 55 MPH in the rain, a vehicle in front of him abruptly slowed down. The contact depressed the brake pedal, but the vehicle jerked to the side. The contact stated that the emergency braking system unexpectedly activated ("slams on") while he was driving due to the Automatic Emergency Braking (AEB) system falsely detecting a potential collision. There were large rocks in the roadway, and there was no traction, causing him to crash into an embankment. The driver's side airbag did not deploy. The other airbags in the vehicle had deployed. The contact sustained a fractured rib, and medical attention was provided at the hospital. The vehicle was towed to a towing company. There were no reported fires. A police report was filed. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The vehicle was taken to an independent mechanic, where an unknown diagnosis was completed. The vehicle was not repaired. The manufacturer was contacted, but no assistance was provided. The failure mileage was unknown.

Brake Feature Malfunction Vehicle Details: •Model: Tesla Model 3 •Year: 2023 (approximately 1 year old) •Mileage at Incident: ~11,000 miles Incident Description: On 10/29, while manually driving my Tesla Model 3 on a public roadway, I experienced a critical braking failure. As I approached a vehicle in front of me that was decelerating, I initiated regenerative braking, then immediately applied the brake pedal forcefully. Despite pressing the brake pedal hard multiple times, the vehicle did not decelerate as expected and ultimately collided with the vehicle ahead. Throughout this incident, no collision warning, automatic braking, or other safety features activated, despite having all safety features enabled. This failure significantly impacted my confidence in the vehicle’s braking and safety systems. After the accident, I reviewed the Tesla incident report, which shows I attempted to brake but that acceleration was not reduced until the collision occurred. Despite the report documenting my attempts to brake, the system did not function properly, suggesting a potential mechanical or software defect in the braking and/or safety alert systems. Aftermath: •My vehicle sustained considerable damage. •I now feel unsafe driving the vehicle, particularly on highways, as I am concerned the brake failure could recur. Request for Investigation: Given the severity of this issue, I am seeking an investigation to determine: 1.Whether there is a defect in Tesla Model 3 braking systems that could result in brake failure under normal driving conditions. 2.If there is an issue with the vehicle’s safety features failing to activate appropriately. This incident has raised significant concerns regarding my safety and that of other drivers, especially given the car’s relatively new condition and low mileage. I would appreciate a prompt investigation into these safety concerns.

On [XXX] around [XXX], my daughter drove her Tesla Model 3 on [XXX] from school. Two strange/scary accidents happened to two different Tesla cars (Model 3 and Y). It was raining with low/medium visibility. One of the cars was driven by my daughter, and luckily, both drivers were safe with very minor injuries. The cars had significant damage but were drivable, and there were no airbags out. These two accidents occurred within 3 to 5 minutes at the “SAME LOCATION.” When I asked them what happened, my daughter and other Model Y drivers described a sudden loss of control, with their cars spinning and becoming unresponsive to steering and braking. They then hit the guardrail on the center line. I checked the video recordings of our car multiple times; no vehicle-to-vehicle collision was involved. I also checked the road to see if there was any oil spillage, but the lane was clean. She didn't use Auto Pilot, FSD, and Cruse Control. The office recorded it as Hydro Plane in his report, but my concern was incidents that happened only to Teslas. Also, when I posted this incident on a Tesla WhatsApp group, multiple Tesla owners reported that they had a similar issue when it was raining. It seems like Sensors malfunctioning in the rain. Also, my daughter was driving below the posted speed (68/70), and she gave a written note to the officer too, but the officer recorded it as 70/70. I need to check that in the Wake County traffic court. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Tesla Motors has two self-driving features, a mode they call enhanced autopilot and Full Self-Driving. Enhanced Autopilot is used primarily on freeways, and allows the car to switch lanes without driver's assistance, while maintaining the speed of traffic. Full Self Driving is a separate system in and of itself that relies on far more sensors, and is far more complex, as it needs to be in order to handle all the nuances of allowing a car to drive itself on and around city streets. During the month of April ,Tesla previewed the supposed improvements in its full self driving mode by releasing it to everyone for free for that month. I was exiting the 101 freeway in Los Angeles, utilizing the enhanced autopilot feature to navigate myself to my destination. At this exit, the car makes a right on Main St, drives downabout 500 feet and then makes another right so that you're briefly traveling underneath the freeway from you'd just exited. As the car made that second right, while on what should have full self-driving mode, the car failed to navigate the angle of that turn and ran right into a steep curb at a fairly fast speed, destroying the right drive train, the right tire, the entire front bumper, and the cars wheel chassis and suspsnesion system all still have to be fixed. I believe the malfunction was caused by the car failing to properly switch vbetween enhancd autopilot and full self-driving if they utilize GPS to mmake that determination, because it felt almost as if the car was trying to switch into the lane to the right (which didnt exist there was the curb there) and not like it was attempting to negotiate or preparing to make a wider turn maneuver. I don't believe it even decelerated as it hit the curb. I broke my toe but otherwise am all right. Tesla won't honor their warranty and is threatening to repo the car they won't fix.

when I was driving my Tesla Model 3 with FSD exiting [XXX] , the FSD directed me to a wrong routing. I corrected the direction by taking over the FSD, the car then lost its full braking system. I was not aware of it until my car slipped backward at a stop and hit a car behind me. The other driver is good enough to let me go, but my Tesla back bumper was damaged. When I got home and read the message on the screen, I was told that the braking hold was disabled, autopilot was disabled, braking charge was disabled, and wheel alignment was disabled, and more. I contacted Tesla and make an appointment half a month later. I was also told that the Tesla recommends to have alignment adjusted every 6000 miles or every 6 months- while I was not aware of this, I thought Tesla is maintenance free. This was what I told Tesla representative then: If this disfunction is safety related, it should be mandatory, not recommended! I feel I was lucky that I only have a small accident, it could be worse. I just dropped my car to Tesla for repair yesterday, the estimated costs was originally $275, then it went up to ~$1500, then ~$1800, When I was talking to a representative, the costs increased to $2167 in a few minutes! I asked why the prices go up, they said the previous prices are mistakes, and if I don't want to pay, I can drive my car home! I believe this happens to many other Tesla users as well, it needs to be addressed before more accidents and damages. The fragile safety operation and the way Tesla treat its customer are not acceptable, at least to my case. Thanks for your attention, if you need more information about my report, or have any question, please feel free to contact me.

I was driving behind someone when a suv came over from left lane into the right lane in front of the cars that were in Front of me and made a sudden turn into a business. I was already applying the brake and was the 3 second rule behind the car in front of me, however the car did not stop as I slammed on the brakes as hard as I could. There have been other times that the car will automatically slammed brakes on because it feels that it need to…when it’s not necessary at all. But the other day when I needed the brakes to help me stop abruptly…they failed to do so. I hit the car in front of me and was cited as well. If I had been going faster..this could have been way worse. This definitely needs to be evaluated on Teslas. I have a dahcam video that I’m unable to upload.

As I was approaching my off ramp (which has a very tight turn), my automatic brakes failed which caused me to slam onto the brakes, and skid into one of the off ramp signs. All 3 of my children were in the back, the back driver side window shattered, I lost my driver side mirror, and there was damage done to the back door and wheel well (all on the driver's side). Although the damage looked minimal, no one was willing to work on the vehicle and I was strongly encouraged by my insurance company to claim it as a total loss. Granted, I had this vehicle for approximately 2 months, and had put at least $4,000 into it.

On Jan. 1, 2024 at around 2:19-2:20PM, the vehicle in front of me made a sudden brake causing my vehicle to trigger the Automatic Emergency Brake. My foot was on the brake pedal as well, I even floored the pedal to make my car stop right away but it continued anyway, the pedal felt so loose/soft. My car almost made a full stop but when the vehicle in front of me started moving, the car started to somehow accelerate, I was confused as to why the car was moving when my foot was firmly pushing the brake. This unexpected move caused me to rear-end the vehicle in front when they abruptly stopped for the second time. My thought is since the car in front moved, the Tesla thought the vehicle in front was no longer a threat and stopped applying the brake to make a full stop. I watched a lot of AEB videos online. 1. Automatic Emergency Brake - malfunctioned, maybe, the car log has it but I took a photo that AEB was in progress during the incident 2. My experience is similar to a car without a brake - no matter how hard I pushed the brake pedal, the car didn't stop. It's frightening because I'm out of control over the situation. 3/4. My car was already repaired but I haven't taken it to a Tesla Service Center to inspect the system - the manual brake is working though 5. There were chimes and screen notifications that an Automatic Emergency Brake was in progress. I can upload the dashcam recording if you need it.

Summary: FSD malfunctioned, failed to disengage, causing loss of steering control, thus causing car to steer into wrong lane and resulting in an accident. Tesla Service Center refused to inspect unless car is fixed. Car was sent to Crash Champions ( autobody shop) and was quoted $35k to fix. Car was deemed as totaled by Tesla insurance. No response from fsdbeta@tesla.com I suspect that the latest FSD software update has caused my car to lose control. Time of incident: 19:28 pm Location : [XXX] , [XXX] Entering from [XXX] . Weather condition: Clear night, well lit. Low traffic. What happened:
 My car has been driving in FSD on Lawrence Expressway and it was doing everything correctly. Approaching that upcoming tight bend, the FSD slowed down the car, and I took over by steering the steering wheel to the right to deactivate FSD and taking the tight turn, right before the white rows of triangles on the street. At this moment, the steering wheel forcibly turned to the opposite direction (i.e. left). I tried to correct the steering wheel by turning right even more, but the steering wheel wasn’t responding to my input for a split second. At this moment, my car is now on the wrong lane of Wildwood Ave and my car finally responded to my steering input. I had to swerve in the opposite direction to avoid the incoming traffic and ended up brushing against an SUV, followed by an impact on the curb, before finally slowing down. Seeing that there was incoming traffic from the back, I drove down to a residential street to park my car for safety reason. The SUV driver called the police to handle the situation, we had our information and testimonies recorded down. I have already followed the safe practices of driving with FSD according to the manual, but in this situation, I am not certain which technology is responsible for causing my car to override my manual steering input. This led to me to question the driver safety systems in this car. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Tesla Model 3 Policy #: [XXX] Claim Number: [XXX] I hope this email finds you well. I am writing to report an incident involving my Tesla Model 3 (Blue) and to initiate the process for an insurance claim. The incident occurred on [XXX], at approximately 2:15 PM. My fiancée was the driver of the vehicle at the time of the incident. Incident Details: - Date: [XXX] - Time: Approximately [XXX] - Vehicle: Tesla Model 3 (Blue) Location: The incident took place on the freeway merge from [XXX], where it merges onto [XXX]. Heading home. Circumstances: My fiancée was operating the vehicle in Autopilot mode while maintaining her hands securely on the steering wheel. As she approached the freeway merge from ramp [XXX], heading onto [XXX], she experienced an unexpected jolt. Despite her continuous control of the steering wheel, the Autopilot system seemed to be accelerating without her input. Simultaneously, my fiancée felt a sudden tire malfunction, which resulted in a significant loss of control over the vehicle. Despite her best efforts to maintain the car's position within the lane, the Tesla Model 3 veered off the freeway and entered the adjacent Ravine area. Impact and Airbags: Upon entering the Ravine area, the vehicle experienced a collision. multiple plants/highbrush/uneven terrain as well as having to maneuver around 2 large palm trees which resulted damage to side mirror. Notably, none of the vehicle's airbags were deployed during the incident, and there were no sensor alerts, except for the tire pressure warning light. Also there wasn't any record of dashcam recording when we checked the car. We are seriously concerned that the airbags did not deploy , attached are photos concerning the damage. I would like to emphasize that my fiancée was diligently following safety guidelines and had her hands on the steering wheel while using Autopilot. This incident occurred suddenly and unexpectedly.
