   On [XXX], the Walmart Auto Care Center on Thomasville Rd in Tallahassee, FL installed four Goodyear Reliant All-Season tires, size 235/45R18 94V (standard load), on my 2021 Tesla Model 3 Standard Range Plus (approximately 75,000 miles). The vehicle's door placard specifies 235/45R18 at 42 PSI cold, and the original-equipment specification for this vehicle is 235/45R18 98 XL (extra load). The installed tires carry a lower load index (94 = 1,477 lbs per tire) than the vehicle requires (98 = 1,653 lbs per tire). The tires were delivered underinflated at approximately 35-37 PSI instead of the placard-required 42 PSI cold. After I inflated them to 42 PSI, the right-rear tire initially would not hold pressure and dropped to approximately 31 PSI, indicating a bead-seating or valve defect from installation; it later accepted 42 PSI but requires monitoring. My normal commute involves sustained highway driving at 70+ mph. Operating at highway speeds on tires rated below the vehicle manufacturer's specified load index, combined with underinflation and a suspected bead/valve installation defect causing pressure loss, creates a risk of heat buildup, tread separation, or sudden blowout and loss of vehicle control. Walmart did not correct the installation: staff attempted to install only three of the four correct replacement tires and later told me to purchase an additional tire at my own expense. I declined both. No crash, fire, injury, or police report resulted. The tires remain on the vehicle pending resolution. This complaint documents the safety hazard created by the incorrect tire fitment and defective installation.

   I have a model 3 2021 Tesla. I noticed that several times it gives me the alert for steering wheel malfunction when it rains. In these instances the car will completely froze in the middle of the highway. I noticed Tesla had a recall for the 2023 Tesla’s for the same issue but failed to inspect the 2021 that also has similar issues. I think this is a huge safety issue that’s a manufactured issue that could have cost me my life

   I am reporting a repeatable safety problem with FSD Lite's end-to-end parking behavior. On July 22, 2026, FSD Lite reversed the vehicle into a solid concrete garage wall while backing into a parking space. The vehicle did not stop before hitting the wall and sustained a scrape. On September 20, 21, and 22, 2026, FSD Lite selected parking spaces and began reversing toward parked cars. I had to intervene each time to prevent a collision. When I select the parking space myself, the maneuver works correctly. A previous software update briefly fixed the problem, but it returned after the vehicle updated to FSD Lite v14.1 Lite, software build 2026.26.6.5. This is a repeatable reverse-parking safety defect that can cause property damage and could injure someone. No one was injured, and no other property was damaged. The vehicle and its logs are available for inspection. Please review the FSD parking-space selection, reverse path planning, obstacle detection, and braking behavior for these events.

   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.

   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 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.

   Tesla replaced the windshield on my 2021 Model 3 at the Tesla Service Center in Schaumburg, IL. Days after the installation, following a light rain, a film appeared on the exterior surface of the glass. In the presence of moisture the film hazes over and substantially obscures forward visibility from the driver's seat. The first occurrence was on 8/22/2026 while leaving a venue in heavy pedestrian traffic. Forward visibility was significantly degraded. During that drive the vehicle's driver-assist system issued a take-control prompt and returned control to the driver. The system did not display a reason for the prompt, so I cannot attribute it; I am reporting that it occurred while visibility through the windshield was degraded. The condition is not removable by normal means. Windshield wipers and washer fluid do not clear it. The defroster/defogger does not clear it, which rules out interior condensation. It required manual scrubbing to reduce, and it has recurred repeatedly since. It presents only in high humidity or after precipitation; in dry conditions the glass appears normal. The condition did not exist prior to the windshield replacement. I have photographs taken from the driver's seat showing the obscured view. I reported this to Tesla on 8/22/2026 through two in-app channels; both were closed without a response. I escalated by email on 8/24/2026. The service manager responded and scheduled an inspection. As of this filing the substance has not been identified, no cause has been determined, and no correction has been made. The condition remains active. I am filing because a windshield that intermittently obscures forward vision under ordinary weather conditions is a driving hazard, and because the vehicle has been operated in that condition while awaiting resolution. No crash, injury, or fire has occurred.

    My 2021 Tesla Model 3 with approximately 70,000 miles developed front suspension problems. It began with squeaking, creaking and groaning, similar to a rusty playground swing, especially while turning or when the suspension moved. The noise was worse in hot weather and progressively became extremely loud and constant during normal driving. I also began hearing intermittent knocking/"bonking" or clunking. I could even hear the suspension when the vehicle compressed as I sat in the driver's seat. There were no warning lights or messages. Tesla inspected the vehicle and diagnosed both front lower lateral links and both front lower compliance links as needing replacement, along with an alignment. Tesla estimated approximately $1,960. CPR EV Repair replaced the diagnosed lower suspension components. After removal, the bushings showed significant visible deterioration, including cracked, torn and separated rubber around the inner sleeves. CPR EV also advised that the front upper control arms were worn and would need replacement. I was concerned for my safety because failure or separation of a deteriorated front suspension component while driving could affect steering or vehicle stability and potentially cause loss of control. Although I did not experience a complete separation or crash, the rapidly worsening and eventually constant symptoms made me concerned about continuing to drive. I have Tesla's estimate, CPR EV documentation and photographs of the deteriorated components after removal.

    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.

    Passenger side view mirror intermittently gets stuck in the "reverse" position while in drive gear. I have the side view mirrors settings to where they are in a certain position when in reverse gear, and then a different position when in drive gear. I will reverse out of a parking spot and then proceed on my drive. Every now and then, the passenger side mirror will still be in the "reverse" position while driving and I only notice it when making a lane change and looking at the mirror and its pointed down at the ground in its reverse position. This has distracted me a few times as I expect the mirror to be in the normal drive position and I'm unable to see any cars in my blind spot. The issue has never occured on the driver side mirror, and has happened for the past few months. I have to correct this each time it does this by going into the mirror settings and hitting the reset position button.

    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.

    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)

    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.

    The high voltage battery on my 2021 Tesla Model 3 Standard Range suddenly failed without any prior warning or gradual degradation. The vehicle was consistently achieving approximately 180 miles of range per full charge. Overnight, the battery charge was restricted to approximately 30% capacity, reducing usable range to roughly 30 miles. No warning signs or symptoms appeared prior to this failure. The failure was sudden and immediate. The vehicle displayed the alert "Maximum Battery Charge Level Reduced / OK to Drive, Schedule Service." The battery has been confirmed by a Tesla Service Center as having an internal fault. The only remedy offered by Tesla is full battery replacement at a cost of approximately $9,000 to $14,000 depending on the option selected. This failure poses a safety risk as the severely limited range can result in the vehicle becoming stranded unexpectedly, particularly during highway driving or in areas without nearby charging infrastructure. The failure occurred approximately 6 months after the battery warranty expired with no prior indication of degradation, suggesting a potential defect in the battery unit. The vehicle has been inspected by a Tesla Service Center and the fault has been confirmed. The component is available for inspection upon request.

    My steering suddenly got extremely stiff on the highway while driving. There was a warning that assist will be reduced but no assist was present. I had to use all my strength to turn the steering and pulled into a parking lot with great difficulty. Then I reset the main computer and the power steering was functional again. I was lucky since the traffic was moving slower than usual but it could have been very dangerous and was a major safety concern.

    On July 1, 2026, the vehicle was serviced by the manufacturer for GPS and camera malfunctions, and the vehicle computer was replaced. On the morning of July 2, 2026, during the first use of Autopilot after that repair, the vehicle experienced repeated serious driver-assistance malfunctions over a short period while traveling on a highway. While Autopilot was engaged, the vehicle repeatedly moved/steered toward the center of the road and near the path of a truck in an adjacent lane. The truck nearly struck the vehicle. The driver had to manually intervene to maintain control and avoid a potential collision. Video of the incident is available upon request and shows the truck and manual intervention. The vehicle was returned to the manufacturer service center the same day. The service center reviewed logs, performed an inspection/test drive, and stated that no hardware faults or issues were found and that the test drive was normal. However, the incidents were intermittent, occurred during highway Autopilot use, occurred the morning after a computer replacement related to GPS/camera systems, and were captured on video.
