The contact owns a 2021 Tesla Model 3. The contact stated that while the vehicle was set to Self-Driving Mode, the vehicle suddenly stopped abruptly without the brake pedal depressed. The contact depressed the accelerator pedal immediately to continue driving. The vehicle was taken to the dealer three times. The dealer reset the mirrors and sensors; however, the failure persisted. The vehicle had not been repaired. The dealer suggested that the contact purchase another vehicle. The manufacturer was not made aware of the failure. The failure mileage was unknown.

After a Tesla-delivered over-the-air software update, my 2021 Tesla Model 3 equipped with Hardware 3 experienced loss of the rear-view camera along with other camera and Autopilot-related functions. The exact date the condition first appeared is unknown, but it occurred after the software update. Camera calibration later became stuck and resets/recalibration did not restore functionality. Tesla Service inspected and reproduced the problem. Tesla documented camera alerts, inability to activate Autopilot, alerts for both pillar cameras and the front-main camera, proper voltage to the cameras, no short to body, and no change after testing a known-good camera. Tesla concluded that the affected cameras share a deserializer path internal to the HW3 car computer and diagnosed an internal car-computer failure requiring complete computer replacement and camera calibration. The safety concern is loss of the rear-view camera and multiple camera-based driver-assistance functions, reducing rear visibility and eliminating features that rely on those cameras. Tesla did not identify the root cause of the internal HW3 failure or establish that the preceding software event could be excluded as a cause, trigger, or contributing factor. Tesla has separately acknowledged in NHTSA Recall 26V283 that software on certain HW3-equipped Model 3 vehicles can prevent camera streams from reaching the MCU and result in loss of the rear-view camera image. I am not claiming that recall necessarily applies to this specific failure; I am reporting the similar sequence so NHTSA can determine whether there may be a broader defect pattern. The vehicle remains unrepaired and is available for inspection upon request.

The adaptive cruise control on Tesla vehicles is dangerous. The model in question is a 2021 Model 3 but its an issue with many model years. The cruise control tends to get confused and applies the brakes during normal driving leading to very unsafe conditions for the Tesla and anybody behind it. The issue can happen in any environment and from 1-2 times per drive. There are no warnings or indications that the car is about to apply the brakes. The car has not been inspected by a service center but is in good working condition.

The front suspension became loose and produced a clunk while driving. The vehicle was taken in the same day. Two independent shops examined it and neither could perform the repair. One reported that a nut for the lower suspension link fasteners was still loose inside the vehicle structure and could be heard moving, and that the cause was unknown. The vehicle was then taken to a manufacturer service center. Its printed factory invoice diagnosed that the captive nuts for the lower subframe links had failed. The front subframe, both front lower lateral links, the front lower compliance link assemblies and the front aero shield were replaced, followed by a four-wheel alignment and a post-repair test drive. There was no collision, no impact damage and no tampering. The failure occurred at approximately 41,766 miles. SAFETY RISK: the lower lateral and compliance links locate the front wheels. Fasteners securing them backing out or failing can allow a link to separate from the subframe, shifting alignment and affecting steering control. This vehicle is driven regularly at highway speed, often with driver assistance engaged, and by more than one driver in the household. A separation at speed could have caused a loss of control. WARNING SYMPTOMS: an audible clunk from the front suspension and a loose-feeling front end, first noticed shortly before the vehicle was taken in. No warning lamp or message appeared. CONFIRMATION: the failure was diagnosed and repaired by the manufacturer's own service center, and the diagnosis appears as printed text on the factory repair invoice, which is available. The replaced parts may no longer be available for inspection. This vehicle has no open or completed suspension recall. Existing recall campaigns covering front suspension lateral link fasteners on this model did not include it. The repair was paid out of pocket.

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)

The contact owns a 2021 Tesla Model 3. The contact stated that the trunk strut failed, and the lift fractured, causing the rear glass to crack. There was a long crack from the edge to the top of the glass. The contact's husband cut the strut because the vehicle could not be driven with the truck ajar. A service appointment was scheduled on the App by text with the local dealer. A message was sent to the Tesla manufacturer. The failure mileage was approximately 82,000.

I am reporting a safety concern regarding the glovebox fascia on my Tesla Model 3. The material on the glovebox trim is peeling and separating, which appears to be caused by prolonged exposure to heat inside the vehicle. The peeling fascia creates concerns about the durability and integrity of the interior component, as the material may continue to deteriorate over time. Loose or damaged trim could potentially interfere with the proper use of the glovebox, create sharp edges, or become a distraction while driving. I am requesting that Tesla inspect the affected area and determine the appropriate repair or replacement to ensure the vehicle remains safe and maintains proper interior component quality.
