2026 Tesla Model 3

The Office of Defects Investigation (ODI) is opening this Engineering Analysis to evaluate Tesla’s Full Self Driving Beta and Full Self Driving (Supervised) (collectively, FSD) degradation detection system. The focus of this investigation will be to assess the system’s ability, when encountering reduced roadway visibility conditions, to detect degradation and alert the driver with sufficient time to respond. ODI will evaluate the performance of FSD in degraded roadway conditions and the updates or modifications by Tesla to the degradation detection system, including the timing, purpose, and capabilities of the updates, and Tesla’s assessment of their safety impact. Tesla’s FSD is an advanced driver assistance system (ADAS) that relies exclusively on vision-based cameras and the related FSD software to detect and respond to the roadway ahead, projecting a path forward based on traffic control devices, vehicles, pedestrians, and the roadway itself. When Tesla began transitioning away from using both cameras and radars to an exclusively camera-based approach, known as Tesla Vision, in mid-2021, it developed and implemented a degradation detection system that it deployed by a software update to existing and new Tesla vehicles. On June 28, 2024, the day after Tesla submitted the SGO report of the November 28, 2023 fatal crash listed in this document, Tesla began developing an update to the degradation detection system. At this time, ODI does not have information on when the update was deployed and which vehicles have the updated system. ODI discussed individual incidents and its initial findings during the PE phase of its investigation with Tesla. As part of those discussions, Tesla’s post-incident analysis indicated that the update to the degradation detection system, had it been installed on the vehicles at the time, may have affected 3 of the 9 incidents identified by ODI. Tesla also described internal data and labeling limitations that prevented a uniform identification and analysis of crash events with the subject system engaged. ODI believes this limitation could have led to under-reporting of subject crashes over portions of the defined time-period. Available incident data raise concerns that Tesla’s degradation detection system, both as originally deployed and later updated, fails to detect and/or warn the driver appropriately under degraded visibility conditions such as glare and airborne obscurants. In the crashes that ODI has reviewed, the system did not detect common roadway conditions that impaired camera visibility and/or provide alerts when camera performance had deteriorated until immediately before the crash occurred. Review of Tesla’s responses revealed additional crashes that occurred in similar environments and where the system either did not detect a degraded state, and/or it did not present the driver with an alert with adequate time for the driver to react. In each of these crashes, FSD also lost track of or never detected a lead vehicle in its path. In upgrading PE24031 to an Engineering Analysis (EA), ODI will gather further information on the updated degradation detection system, including the status of updating vehicles and scope of compatible vehicles, the system’s visibility degradation detection capability, and alerts or warnings to the driver. Lastly, ODI will conduct analysis on six recent potentially related incidents. These incidents can be found at NHTSA.gov under the following SGO report identification numbers: 13781-11937, 13781-13211, 13781-13569, 13781-13633, 13781-13693, 13781-13788. The crashes included in the failure report summary can be found at NHTSA.gov under the following SGO report identification numbers: 13781-8004, 13781-7181, 13781-7381, 13781-7767, 13781-7964, 13781-8977, 13781-9267.

The Office of Defects Investigation (“ODI”) is opening this Preliminary Evaluation (PE) to assess the scope, frequency, and potential safety consequences of FSD executing driving maneuvers that constitute traffic safety violations. This investigation concerns versions of FSD that Tesla has labeled as "FSD (Supervised)" and "FSD (Beta)." Tesla characterizes FSD as an SAE Level 2 partial automation system requiring a fully attentive driver who is engaged in the driving task at all times. Level 2 partial automation systems are designed to support and assist the driver in performing certain aspects of the driving task, requiring a driver to supervise and intervene as necessary.  The driver remains fully responsible at all times for driving the vehicle, including complying with applicable traffic laws. ODI’s investigation will therefore focus, in particular, on whether certain driving inputs within the control authority of FSD forestall the driver’s supervision when they are unexpectedly performed. ODI has identified a number of incidents in which the inputs to the dynamic driving task commanded by FSD induced vehicle behavior that violated traffic safety laws. Although reports of this nature span a variety of behaviors, the reports appear to most commonly involve two types of scenarios. The first type of scenario involves a vehicle operating with FSD proceeding into an intersection in violation of a red traffic signal. The second type of scenario involves FSD commanding a lane change into an opposing lane of traffic. With respect to the first type of scenario, ODI has identified 18 complaints and 1 media report alleging that a Tesla vehicle, operating at an intersection with FSD engaged, failed to remain stopped for the duration of a red traffic signal, failed to stop fully, or failed to accurately detect and display the correct traffic signal state in the vehicle interface. Some complainants also alleged that FSD did not provide warnings of the system's intended behavior as the vehicle was approaching a red traffic signal. ODI has identified six Standing General Order ("SGO") reports in which a Tesla vehicle, operating with FSD engaged, approached an intersection with a red traffic signal, continued to travel into the intersection against the red light and was subsequently involved in a crash with other motor vehicles in the intersection. Of these incidents, four crashes resulted in one or more reported injuries. At least some of the incidents appeared to involve FSD proceeding into the intersection after coming to a complete stop. ODI's pre-investigative work, including coordination with the Maryland Transportation Authority and State Police, indicated that the problem may be repeatable, given that multiple subject incidents occurred at the same intersection in Joppa, Maryland. NHTSA understands that Tesla has since taken action to address the issue at this intersection. With respect to the second type of scenario, ODI has identified 2 SGO reports, 18 complaints, and 2 media reports alleging that a Tesla vehicle, operating with FSD engaged, entered opposing lanes of travel during or following a turn, crossed double-yellow lane markings while proceeding straight, or attempted to turn onto a road in the wrong direction despite the presence of wrong-way road signs. Likewise, ODI has identified 4 SGO reports, 6 complaints, and 1 media report alleging that a Tesla vehicle, operating with FSD engaged, proceeded straight through an intersection in a turn-only lane or executed a turn at an intersection in a through lane despite the presence of lane markings or signals. Complaints also alleged that FSD did not provide warnings of the system's intended behavior. Some complaints alleged that more than one of these failures occurred and, as such, the numbers are not cumulative. Some of the reported incidents appeared to involve FSD executing a lane change into an opposing lane of travel with little notice to a driver or opportunity to intervene. ODI’s review will assess whether there was prior warning or adequate time for the driver to respond to the unexpected behavior or to safely supervise the automated driving task. This review will assess any warnings to the driver about the system's impending behavior; the time given to drivers to respond; the capability of FSD to detect, display to the driver, and respond appropriately to traffic signals; and the capability of FSD to detect and respond to lane markings and wrong-way signage. NHTSA's review will also consider any updates or modifications to the system(s) that may affect the performance of FSD with respect to obeying traffic safety laws and signals. This assessment will focus, in particular, on the types of traffic safety violations described above, as most reports identified thus far have centered around those behaviors. While the behaviors under investigation appear to occur most frequently at intersections, NHTSA’s investigation will encompass any other types of situations in which this behavior may arise, such as when traveling adjacent to a lane of opposing traffic or when approaching railroad crossings. If other evidence received during this investigation involve other types of traffic safety violations, those may be considered as part of this assessment as well.

The Office of Defects Investigation (“ODI”) has identified numerous incident reports submitted by Tesla, Inc. (“Tesla”) in response to Standing General Order 2021-01 (the “SGO”), in which the reported crashes occurred several months or more before the dates of the reports. The majority of these reports involved crashes in which the Standing General Order in place at the time required a report to be submitted within one or five days of Tesla receiving notice of the crash. When the reports were submitted, Tesla submitted them in one of two ways. Many of the reports were submitted as part of a single batch, while others were submitted on a rolling basis. Preliminary engagement between ODI and Tesla on the issue indicates that the timing of the reports was due to an issue with Tesla’s data collection, which, according to Tesla, has now been fixed. NHTSA is opening this Audit Query, a standard process for reviewing compliance with legal requirements, to evaluate the cause of the potential delays in reporting, the scope of any such delays, and the mitigations that Tesla has developed to address them. As part of this review, NHTSA will assess whether any reports of prior incidents remain outstanding and whether the reports that were submitted include all of the required and available data. The SGO reports cited in the Opening Resume, can be found at NHTSA.gov/SGOCrashReporting under the following SGO 2021-01 report IDs: 13781-11020-1 13781-10844-1 13781-10843-1 13781-10530-1 13781-10160-1 13781-10159-1 13781-10157-1 13781-10146-1 13781-10122-1 13781-10098-1 13781-10097-1 13781-10096-1 13781-10095-1 13781-10094-1 13781-10093-1 13781-10023-1 13781-10022-1 13781-10021-1 13781-10020-1 13781-10017-1 13781-10016-1 13781-10015-1 13781-10014-1 13781-10013-1 13781-10012-1 13781-6047-1 13781-9930-1 13781-9917-1 13781-9928-1 13781-9925-1 13781-9924-1 13781-9923-1 13781-9922-1 13781-9835-1 13781-9834-1 13781-9833-1 13781-9832-1 13781-9831-1 13781-9830-1 13781-9829-1 13781-9827-1 13781-9818-1 13781-9780-1 13781-9779-1 13781-9778-1 13781-9777-1 13781-9775-1 13781-9774-1 13781-9773-1 13781-9772-1 13781-9771-1 13781-9770-1 13781-9728-1 13781-9688-1 13781-9715-1 13781-9714-1 13781-9713-1 13781-9712-1 13781-9711-1 13781-9710-1 13781-9709-1 13781-9696-1 13781-9695-1 13781-9694-1 13781-9693-1 13781-9692-1 13781-9691-1 13781-9690-1 13781-9687-1 13781-9686-1 13781-9342-1 13781-9319-1 13781-9019-1 13781-8910-1 13781-8732-1 13781-8712-1 13781-8310-1 13781-7897-1 13781-7895-1 13781-7835-1 13781-7798-1 13781-7797-1 13781-7758-1 13781-7757-1 13781-7756-1 13781-7755-1 13781-7667-1 13781-7399-1 13781-7398-1 13781-7397-1 13781-7396-1 13781-7395-1 13781-7394-1 13781-7393-1 13781-7389-1 13781-7388-1 13781-7387-1 13781-7386-1 13781-7385-1 13781-7383-1 13781-7187-1 13781-7186-1 13781-7185-1 13781-7184-1 13781-7181-1 13781-7023-1 13781-6399-1 13781-6389-1 13781-6388-1 13781-6387-1 13781-6386-1 13781-6379-1 13781-6378-1 13781-6377-1 13781-6375-1 13781-6214-1 13781-6172-1 13781-6155-1 13781-6154-1 13781-6122-1 13781-6120-1 13781-6118-1 13781-5800-1

On Sept 22 2026at approximately 10:26 AM, my Tesla vehicle was involved in a low-speed, 5 -10 mph rear-end collision while the Full Self-Driving (FSD) Supervised automation system was engaged. The vehicle failed to initiate a timely braking sequence for a lead vehicle, resulting in an impact. There was a sudden accleration right before the hit along with a sudden braking. Critical Safety Failures & Discrepancies: 1. Unwarned System Degradation: Following the incident, Tesla Service technicians reviewed my vehicle diagnostics and explicitly stated that internal logs flagged the FSD system performance as degraded or "suspect" since the beginning of September 2026. However, prior to the crash, the vehicle provided zero driver-facing warning messages, dashboard alerts, or mobile application notifications indicating that the automated safety systems were compromised or operating with a defect. 2. Telemetry Log Contradiction: Tesla's initial internal review claims that the vehicle's telemetry indicates an accelerator pedal override by the driver. I explicitly state that my foot was not on the accelerator pedal and no such override was physically made. There is an active sensor tracking or system logging discrepancy regarding driver inputs during this FSD failure. Evidence Maintained: I have preserved the complete, 4-angle synchronized TeslaCam dashcam footage of the incident on my computer as visual proof of the vehicle's un-accelerated 5 mph forward creep. Furthermore, I have submitted an official Data Privacy Request to Tesla to force the extraction of the raw, unredacted vehicle telemetry logs (DI_accelPedalPos) to legally dispute their pedal position claims. I am filing this report to assist NHTSA's active investigations into Tesla Autopilot/FSD traffic safety violations, specifically concerning automated braking failures and inaccurate driver-override telemetry classification.

The front windshield camera for FSD gets hazed and obstructs the front camera. Tesla say it’s from the gases that come from the interior from the vehicle being hot temperatures. My problem why did they not design the cameras like they did in the side puller protecting it from the interior gases. Now Tesla says they’ll clean it for 65.00. I just bought the car in March

Incident

Sep 18, 2026

When using Tesla's Full Self Driving (supervised) speed control is erratic and not subject to the driver's control, such as it would be when using adaptive cruise control. As a result, the available speed modes (sloth, chill, standard, hurry and Mad Max) can cause the vehicle to dangerously exceed speed limits and at times to drive well below the posted speed limit, causing confusion and frustration to following drivers. There is no reason why the software cannot be changed to a safer method that would permit the driver to select the speed at which the car will travel, i.e. the speed limit, similar to adaptive cruise control found in most modern vehicles. When the operator of a vehicle is not in charge of the vehicle's speed, this is inherently dangerous.

My Tesla was operating under FSD at 9pm on a dark country road. I was traveling at 45mph and vehicle randomly applied hard emergency braking and I had to take over. It appeared that the vehicle may have been responding to a dark oil stain or possibly a mailbox. Had another vehicle been closely behind me, there would’ve been a collision.

On August 26, 2026, at approximately 8:56 AM, I entered a public parking garage in Washington, DC. Full Self-Driving (Supervised) was engaged and controlling the vehicle during a reversing maneuver. I remained attentive to the vehicle's surroundings, including pedestrians and surrounding traffic. While reversing under FSD (Supervised), the vehicle's right rear corner collided with the corner of a stationary structural pillar in the parking garage. I did not command the vehicle to steer into the pillar. Upon becoming aware of the impact, I immediately applied the brake. There were no injuries. The collision resulted in damage to the right rear area of the vehicle. After the incident, I photographed and recorded the scene and vehicle damage and saved the available Tesla Dashcam footage. I also requested the vehicle data from Tesla. I am reporting this incident because the vehicle collided with a stationary structure while FSD (Supervised) was engaged and controlling the reversing maneuver. I do not know the specific technical cause of the incident. The vehicle and available recorded data can be made available for inspection upon request.
