Component: Lane Support System — Emergency Lane Keeping (ELK) Part of standard Autopilot safety suite (not FSD) activated without valid lane detection data and pushed the vehicle into the oncoming lane of traffic on Ohio State Route [XXX]. The system then aborted mid-intervention (LSS_STATE_ABORT), leaving the driver in the oncoming lane. The resulting head-on collision killed both drivers — the [XXX] Tesla driver and the driver of the oncoming vehicle. Two people died because of this ELK malfunction. Tesla's own telematics data confirms the following sequence: 5At 23:51:17.420 UTC, the Lane Support System activated Emergency Lane Keeping (LSS_STATE_ELK). 6At 23:51:17.652 UTC (232 milliseconds after activation), the system logged ALC_UNAVAILABLE_NO_LANES — confirming it had no valid lane detection data during the intervention. 7At 23:51:17.755 UTC (335 milliseconds after activation), the system logged LSS_STATE_ABORT — the system cancelled itself mid-intervention. 8During the 335-millisecond intervention, the vehicle's steering angle reached -16.79 degrees leftward and lateral acceleration measured +1.200 m/s² leftward — both confirming the vehicle was pushed into the oncoming lane. 9The driver responded with the largest steering torque (-5.08 Nm rightward) and largest rightward steering angle (+19.50 degrees) recorded in the entire telematics file — confirming he was actively attempting to recover. 10 The head-on collision killed both him and the driver of the oncoming vehicle. We requested additional telematics data from Tesla through the Tesla app. A forensic expert has examined the vehicle's ECU motherboard— missing critical fields including continuous yaw rate, high-resolution steering data, ELK steering commands, and lane detection confidence scores. A subsequent request for additional data produced an error message and Tesla has not provided further data. This crash is the exact behavior under PE25012.

Front Seatbelt On March 13, 2026, at approximately 7:51 PM EST (23:51 UTC), the driver of a 2021 Tesla Model 3 was killed in a head-on collision on SR 741 in Warren County, Ohio. Two people died in this crash — the Tesla driver and the driver of the oncoming vehicle. Tesla's own telematics data (provided to the family post-crash) reveals that the driver's seatbelt unlatched at Row 5115 / 23:51:03.269 UTC — exactly 14.15 seconds before the collision. The driver was actively driving at the time, as confirmed by 66 separate steering torque readings between the seatbelt unlatch and the crash, ranging from −1.59 Nm to +2.15 Nm in constantly alternating directions — the signature of active lane-holding. The seatbelt released on its own while the driver was actively steering based on tesla data at approximately 66 mph. No rational driver unbuckles their seatbelt while driving 66 mph on a busy two-lane road. The telematics data proves continuous active driving before, during, and after the seatbelt event. The seatbelt failure is a separate and independent defect from the Emergency Lane Keeping (ELK) system failure that caused the collision (which is the subject of a separate NHTSA complaint). Even if the collision was unavoidable, a functioning seatbelt may have saved the driver's life. The seatbelt failure independently contributed to the fatality. The following data is from Tesla's own telematics file provided to the family: Timestamp (UTC)RowEvent 23:51:03.269 5115 Driver seatbelt status changes from LATCHED to UNLATCHED 23:51:03.269 – 23:51:17.420(row 5115–5311)66 steering torque readings confirm active driving (−1.59 to +2.15 Nm) 23:51:17.4205311ELK system activates (separate defect) ~23:51:19.0—Head-on collision — driver unrestrained — two fatalities Pattern of identical complaints from other 2021 Model 3 owners (ODI 11713076, 11738583, 11684327)

Mar 31, 2026AirbagsDriver assistanceCrash

The components involved are the automatic emergency braking (AEB) system and the airbag system. During the collision, the AEB system did not activate, and the airbags did not deploy. The vehicle is available for inspection upon request. I was driving on a main roadway with no stop signs or traffic controls in my direction when another driver entered from a side street with a stop sign and pulled directly in front of me. I was unable to avoid the collision, and my vehicle was struck the other vehicle. The failure of the AEB system to engage and the airbags not deploying increased the risk of injury to myself and could have posed a risk to others involved. The issue has not been reproduced, and it has not yet been confirmed by a dealer or independent service center. The vehicle has been inspected by police and insurance representatives. The other driver was determined to be at fault. I am in the process of addressing the incident with the manufacturer. There were no warning lights, messages, or prior symptoms indicating any issue with the braking or airbag systems before the collision.

I drove into my neighbor’s driveway to drop her off. As I slowed down and applied the brakes to stop, the car failed to respond. It continued forward, running over the flower and plant pots at the edge of the driveway, crossing the backyard, and finally colliding with the trees and bushes at the rear of the property. All airbags deployed, and the vehicle was damaged beyond repair.

Component/System involved: Advanced Driver Assistance Systems — FSD (Supervised)/Autosteer (Lane Keeping Assistance) and Adaptive Cruise Control. Possible failure to warn/stop (FCW/AEB). Vehicle and data are available for inspection upon request. I preserved dashcam files and requested Tesla to preserve engineering logs and EDR. What happened & safety risk: On [XXX] at ~[XXX] PDT on [XXX] near East Palo Alto, CA, with FSD (Supervised) engaged, the system appeared to misinterpret an exit ramp/gore area as a continuing lane at a highway fork and maintained ~60 mph (posted ~70). As soon as I saw the trajectory was unsafe, I braked and began manual steering takeover, but the vehicle contacted a roadside sign near the gore/shoulder before I could complete the maneuver. I then stopped safely. No other vehicles were struck. Airbags did not deploy. This posed a serious collision risk to me, my passenger, and nearby traffic. Reproduction/confirmation: NOT REPRODUCED. I have not attempted to reproduce the event. UNKNOWN whether the issue has been reproduced by Tesla or a service center yet. Inspection to date: Police responded (report pending). My insurer has opened a claim. I opened a Tesla Service request asking to PRESERVE Autopilot/FSD engineering logs for the incident window and to coordinate EDR extraction; engineering review pending. Vehicle remains drivable. Warnings or symptoms before failure: No audible/visual forward-collision warning was perceived by me and I did not observe automatic emergency braking. No prior warning lamps/messages were noticed before the departure toward the gore. UNKNOWN whether any internal/partial interventions were recorded in logs. Evidence available: Four-camera Tesla dashcam footage saved and backed up (see [XXX] ); precise time window ~[XXX] PDT on [XXX]. I can provide files and cooperate with data retrieval/inspection upon request. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Jul 28, 2025BrakesDriver assistanceCrash1 injury

On [Wednesday, 07/09/2025], I was driving my Tesla Model 3 in rainy conditions when the vehicle suddenly swerved and crashed into a sidewall. The road was wet but not flooded, and I was traveling at a moderate speed. As I lifted my foot off the accelerator to slow down, the car's regenerative braking system engaged abruptly, which I believe shifted weight forward and caused the rear tires to lose traction. This led to hydroplaning and complete loss of control. There were no warning lights or alerts prior to the incident. The road surface did not have visible hazards or standing water that would typically explain a spinout. The tires were moderately worn but within usable limits. As a result of the crash, the car was declared a total loss. The insurance company now has possession of the vehicle. Thankfully, no one was injured, but the crash was severe. After the incident, I researched similar cases and found multiple reports and articles (e.g., AutoEvolution) linking Tesla’s regenerative braking to increased risk of hydroplaning or loss of control in wet or slippery conditions. The regen system eliminates coasting and applies braking force immediately upon throttle lift-off, which appears to be a safety risk in reduced-traction environments like rain, snow, or ice. I believe this issue deserves investigation, as it may affect the safety of other Tesla drivers in similar weather conditions.

Attempting to park. Slowly inching forward while turning left. Vehicle accelerated. (Sudden Unintended Acceleration: SUA) Vehicle jumped a curb, bounced off a tree, dropped off the curb before comping to a stop. Internet search shows other similar reports; attributed, by Tesla, as pedal misapplication. This was not "pedal misapplication". I am not looking for anything.

Without any warning from feel unstable, wobbly, or noisy, my car began pulling hard to the right as I was going straight on a small street. I was going about 10 m-15 miles an hour. My steering wheel did not respond to my efforts to straighten the vehicle and my brakes did not slow the car’s path. I was only stopped by two parked cars on the side of the road that I bounced off of. When I got out, bystanders pointed to the sheared tie rod on the front passenger side. The witnesses stated it was clear from their view that if I had been going faster on a wider street there would have been severe injury Instead of only three cars being damaged. My car was three years old and had passed its annual inspection one week before. The police were called twice but did not come within three hours so the car was towed without a police report.

Aug 9, 2024AirbagsCrash

I am writing to report a serious safety concern regarding the non-deployment of airbags during a recent traffic accident. The incident involved a collision where I was struck on the driver’s side front. Despite the severity of the impact, the airbags did not deploy, which raises significant concerns about the effectiveness and reliability of the airbag system in such scenarios. Incident Overview •Accident Type: Collision with impact on the driver’s side front •Airbag Response: No airbag deployment Safety Concerns The non-deployment of the airbags during this incident is alarming, as airbags are a critical safety feature designed to protect occupants during a collision. In this case, the failure of the airbags to activate could have resulted in serious injury or even death, depending on the circumstances. The lack of deployment suggests a potential defect in the airbag system that may compromise the safety of other vehicles of the same make or model.

The vehicle, a 2021 Tesla Model 3, had an episode of sudden unintended acceleration. I was almost stationary waiting to make a left when the car accelerated by itself, left the road, crossed a grass field at high speed and crashed into bushes. The vehicle was not on auto pilot, it resulted in damage of almost $ 20.000 as estimated by insurance. The vehicle is available for inspection, it will be checked by Tesla service after the damage is fixed. There were no previous warnings, this is the first incident of this kind. It is not clear what component malfunctioned, probably some electric/electronic device in charge of acceleration. It was obviously a very dangerous event that could have jeopardized my safety and/or some others.

I was driving my car on the highway I275 approximatley 5 miles North of St Petersburg Florida. When without reason the car spun to the left very quickly, I did not have any steering control at that moment. If the car had hyro plained it would not have spun out of control so quickly. The road was slightly wet as there was a drizzle but not to any extent to allow the car to spin out of control due to heavy water. My vehicle hit the highway guard rail and was badly damaged.

This accident involved a high speed collision on the 2nd floor of a parking garage at a hospital in a suburb of Houston, Tx. Both the driver and the passenger were killed. A question has arisen as to how the vehicle could have accelerated at such a high rate, in such a short period of time, especially inside a parking garage? When we found out NHSTA was re-opening, the Tesla sudden acceleration issue, we thought it important to include the facts of our accident. Sudden acceleration in this case, raises some concern, taking into account the facts and circumstances surrounding this accident. We have photos of the vehicle if needed.

Jul 19, 2023Crash

This is a report of the accident I was in on July 15, 2023 at 3:00 PM. I was going south on two lane Hwy 160 a couple south miles of Hwy 12 when I pulled out onto a wide, long pullout. When I decided to get back on the highway, I looked back to see a long line of cars coming. My Tesla’s Full Self Driving has Auto Lane Change which switches lanes for you when safe. I figured I would use Auto Lane Change to merge onto the road when safe. I already had the Tesla Navigation on. I turned on the Full Self Drive and my blinker, thinking that it would be a while before the Tesla decided it was safe to merge onto the road. However, the car started moving toward the road almost immediately. I realized that there couldn’t have been a break in traffic already. I turned in disbelief. Just then the left side of the was smashed. I looked ahead to see a SUV swerving back and forth down the road trying to regain control. Then the blur of another car. The SUV was sailing through the air, then it was sliding on its roof. I rushed to the SUV feeling like there was a good chance that people were really hurt or dead. I couldn’t see inside because of the airbags.The driver’s door wouldn’t open. I rushed around the back of the car and saw a dog getting out of the front passenger door followed by a man. The man helped his wife out. Thankfully, they were not hurt. While waiting for the tow truck, one of the fishermen who were hanging around for some reason asked me for my ID. I asked why. He said his car was in the accident and pointed across the highway to over a 15 foot embankment and to about 500 hundred yards away where I saw his car. He said that his car had been parked and was hit by the SUV. With the stress and adrenaline of the accident and because there was only my car and the SUV on the side of the road, I realized that this was the car I had seen in a blur during the whirlwind accident.
