2023 Tesla Model 3

The Office of Defects Investigation (ODI) has received 156 complaints alleging a suspension failure in model year (MY) 2018-2020 Model 3 and MY 2021-2023 Model Y vehicles. The suspension failure involves the detachment of the front lower lateral link, which potentially causes a loss of vehicle directional control. In most cases, there was no advance warning or indication that the suspension failure would occur.  Some cases cite noises occurring prior to failure, but note that the vehicle provides no visual warnings. Once the failure occurs, the vehicle may not be drivable, thus requiring a tow. Tesla has previously recalled vehicles for lateral link detachments through two recalls. Recall 21V-835 addressed 2,791 MY2019-2021 Tesla Model 3 vehicles due to a production issue. Recall 23V-235 addressed 422 2018-2019 Tesla Model 3 vehicles that had experienced similar failures to those recalled under 21V-835. The subject failures for this investigation exceed the scope of these recalls and do not appear to be related to the production issue that prompted those recalls. ODI is opening this Preliminary Evaluation to determine the underlying cause, scope, and severity of the potential problem and to fully assess the potential safety-related issues. To review the ODI reports cited in the Opening Resume ODI Report Identification Number document, go to NHTSA.gov.

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 September 20, 2026, at approximately 10:26 AM EDT, I was driving my Tesla on ON I-76 E MM 332.4 with Full Self-Driving (Supervised) engaged. It was raining, the pavement was wet, and there was heavy road spray. The vehicle's front dashcam recording, time-stamped "Sep 20, 2026, 10:26:02 AM," shows the car traveling in the right lane at about 55-56 mph with the on-screen indicator reading "Self Driving." The vehicle then steered to the right, out of its lane, toward the concrete barrier and roadside embankment. The "Self Driving" indicator disappears about half a second before the vehicle leaves the lane, at about 54 mph. I did not steer or brake before the vehicle left the lane. The vehicle then lost stability, spun across the roadway, and slowed from about 53 mph to nearly a stop, facing against the direction of traffic. While facing oncoming traffic, it was struck by an oncoming white sedan, which sustained front-end damage my car had been declared a total loss. I believe the Full Self-Driving system failed to keep the vehicle in its lane in rain and gave too little or no warning before handing control back to me, leaving no reasonable time to recover. I have kept the original dashcam footage and have sent Tesla a written request to preserve and release all vehicle data for this event, including FSD engagement and disengagement logs, driver-input data, and stability control data. I can provide the footage and any records Tesla releases to NHTSA on request.

Steering becomes very stiff or notchy where you have to pull it out of position or correct it constantly. Doesn't want to return to center! When you stop it returns to normal feeling then as soon as you get up to speed it becomes stiff again.

I have a group of individuals that are hacking all of my accounts and trying to steal my car. They first hacked my emails then my Tesla account and now they are actually on the Teslas computer system and have been in the vehicle accessing the screen. After they hacked the system and stopped updates the car started having a bunch of safety concerns and alerts.The breaks were not working and the vehicle would freely roll when full pressure was applied. The collision system in the car was not working properly. Thinking it was possibly going to be hit by another car it would avoid nothing and jerk me out of the lane and nothing was around at all potentially causing an accident. Then the collision system stopped working all together. The steering system would not communicate properly with the system and kept requesting to be reconfigured with the system. The power train system kept throwing alerts. The tire pressure sensors stopped working and will not retrain now. They keep stopping the software updates now and have an IT admin portal device management program on the system and have complete control of the car’s system. Recently they were checking into enrolling in to fleet developer API to interact with the vehicle at code level. I have tried everything to get them off the account and they live at my apartment building. They are using illegal hacking tools and devices to gain access spyware and malware on all my devices.Tesla has done little to nothing to fix this problem and reports have been made. This is a major safety concern.

I am filing an official safety complaint regarding a severe, premature failure of the front lower suspension system on my 2023 Tesla Model 3. While operating the vehicle, the front lower compliance links (Part numbers: 2188359-10-B, 2188354-10-B) and the lower lateral links (Part number: 1044341-00-G) suffered critical mechanical bushing degradation and structural wear, rendering the front suspension unsafe and compromised.This mechanical breakdown occurred at only 63,584 miles on a three-year-old vehicle under completely normal, standard highway and suburban driving conditions. There has been absolutely no external impact, wheel strike, curb strike, or collision to explain a simultaneous, symmetrical breakdown of multiple heavy suspension components on both the left and right sides of the vehicle. My tires show zero sidewall damage and the wheels have no structural bends, proving the issue is an inherent component lifecycle defect rather than a road hazard.This issue directly correlates with NHTSA Preliminary Evaluation PE26006, which investigates nearly 1.2 million Tesla Model 3 and Model Y vehicles for front lower lateral and compliance link failures. When seeking service, Tesla Service Center personnel attempted to classify this wear due to structural degradation but deny warranty or goodwill coverage. This component vulnerability represents an acute safety risk, as a total failure or detachment of these specific lower links while traveling at high speeds could cause a catastrophic, immediate loss of steering control. I request that the NHTSA include this vehicle in its ongoing investigation to push for a mandatory safety recall.

OKC Tesla Service Center replaced the steering wheel due to delamination over the weekend. The car was dropped off on Friday the 4th of September 2026. I picked the car up on Monday the 7th. On Wednesday the 9th after getting on the highway and getting up to speed the steering wheel came out of the steering column and was physically disconnected from the car. I was able to temporarily get it back into place enough to get the car to a save location to be towed.

On certain Model 3 vehicles, brake lines may be corroded beyond acceptable limits, which may result in loss of brake fluid. Loss of brake fluid will result in a customer facing alert if the fluid reaches the predetermined level to trigger an alert. Upon customer complaint of a low brake fluid alert, evidence of a brake fluid leak, or a failed periodic roadworthiness inspection, inspect the brake lines. If corrosion is found on any of the brake lines, replace all brake lines on the vehicle with new corrosion-resistant parts, in one combined repair. NOTE: Due to dual reduncancy, vehicle safety is not impacted by corrosion on the brake lines.

A firmware diagnosis feature is being introduced on Model 3 and Model Y vehicles that monitors wheel alignment over time. This feature detects changes in wheel alignment that may be related to incorrect tire pressures, degraded ball joints, bushings or damaged suspension links. If the feature determines that an inspection at a Tesla Service Center is required, a customer-facing alert will appear on the touchscreen.
