2021 Tesla Model 3 Problems

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.

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.

As we were normally driving, the car lost power immediately with no warning sign. After the power is lost, brake does not function, electrical door button doesn't function, hazard light doesn't function. Car was able to scroll to a complete stop to the side of the road. The steering wheel is locked. Again, BRAKE DID NOT FUNCTION after the power is lost. No button works, no screen turns on, car is not able to turn to neutral. There was no collision prior and no warning prior. Tried to file a police report. But Officer [XXX], badge # XXX, refused due to there was no collision and no accident.

The forward-facing camera and Autopilot computer system on my 2021 Tesla Model 3 has failed. The dashboard first showed intermittent warnings that "Automatic Emergency Braking is currently unavailable" and "Adaptive headlight features are unavailable." Over several weeks the problem worsened from intermittent to constant, and the vehicle progressively lost its forward road visualization and all active safety features. Using the vehicle's Service Mode diagnostics, the Autopilot computer's Primary (A) processing node reports a "CRITICAL" status. The fault log records repeated alerts including dasMIA (driver-assistance system not responding), aebFault (automatic emergency braking fault), and fisheyeCamInitFault and fisheyeCameraStreamExit (forward camera initialization and stream failures). The cameras themselves are physically clean and unobstructed. Safety risk: the failure disables Automatic Emergency Braking and forward collision avoidance, lane-keeping/driver assistance, and the adaptive auto high-beam headlights. AEB is a critical crash-avoidance system; losing it leaves the vehicle unable to brake automatically for an imminent collision, and the loss of adaptive headlights reduces nighttime visibility. A Tesla service center inspected the vehicle, confirmed the diagnosis, and determined the Autopilot computer — a sealed, solid-state control unit — had failed and required full replacement at approximately $3,400. The vehicle is well under 50,000 miles. This failure appears consistent with the same car-computer power-component shorting failure for which Tesla issued a recall on its newer model-year vehicles. The vehicle and the failed component are available for inspection on request. The vehicle has not been inspected by police or insurance.

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 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.

After Tesla replaced my high voltage battery in May of 2024 all of the following started to happen. Prior to the replacement none of these issues were present. While driving under normal conditions, my 2021 Tesla suddenly and violently steered into an oncoming lane or toward the roadside without any driver input. The steering wheel physically turned on its own with force. Full Self-Driving was NOT engaged at the time of the incident. This was not lane assist correction and occurred without warning. Importantly, the vehicle did NOT issue a warning at the time of the steering event. A “Take Control Immediately” message appeared several minutes AFTER the incident, not before or during, indicating a delayed or failed system response. This defect began immediately after a High-Voltage Battery replacement performed by Tesla Service in May 2024 and has occurred multiple times since. The incident presents a serious safety risk, including loss of vehicle control, roadway departure, or head-on collision. In addition to the steering defect, the vehicle began exhibiting multiple electronic and control anomalies immediately after the High-Voltage Battery replacement. These include navigation/map screen failures, windows adjusting themselves while driving, random “cannot shift into drive” warnings, system failure messages, camera malfunctions, and unexpected screen reboots. These issues did not exist prior to the battery replacement and support the presence of an underlying electrical or control system instability related to the steering defect.

My RWD motor completely went out and lost power on the highway off ramp. Could have turned into a dangerous situation. Not sure why these motors seem to be very unreliable. Tesla has not given me an explanation as to what is exactly causing this. Happens to thousands of owners. And this car is only 5 years old. I had the motor replaced in November 2022 and 3 years later it’s out for good. Now I have to deal with teslas insane costs. I feel like they sold me a defective car.

HVAC system which provides cooling/heating for all the systems including the powertrain, battery, inverters, Full-Self Driving computer malfunctions randomly shutting itself off due to a known issue of failing pressure and temperature sensors. Tesla is aware of this issue where the sensors may fail prematurely and in 2021 they issued a service bulletin SB-21-18-002. I was told It would be fixed with a software update... In other words it was never fixed. Now my car says that cooling and heating may randomly be unavailable due to invalid readings from the pressure and temperature sensors. They want me to pay to have the sensors replaced despite them acknowledging that they have a defect causing premature failure. This issue is safety related because in the event that I was supercharging and the HVAC system shuts down it could potentially lead to a battery fire or thermal runaway. Not to mention that the car left me without heat in subzero temperatures on a roadtrip.

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.

I wrote several months ago about my 2021 tesla model 3 that the rear doors do not have any mechanical door handle release and is a big safety concern also how can a manufacturer get away with this and also not informing the consumer that anyone sat in the back may perish if involved in a accident and can't get out.

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 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.

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 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 the owner of a 2021 Tesla Model 3 and am filing this complaint due to a significant safety concern: my vehicle does not have manual or mechanical releases for the rear doors; only electronic mechanisms are present. In the event of a total power failure, accident, fire, or submersion, rear seat passengers would be unable to exit the vehicle through the rear doors, as there is no physical lever or alternative escape route directly available inside the rear seats. This design poses a serious risk to occupant safety in emergencies, especially for families with children or passengers unable to access the front seat manual releases or trunk escape features. The lack of a rear mechanical release is inconsistent with standard automotive safety practices and could lead to injury or loss of life if electronic door access is disabled. It’s important to note that newer Tesla models now include manual rear door release mechanisms, demonstrating that Tesla recognizes the safety benefit and necessity of this feature. Owners of earlier models, like mine, are left without this critical safety upgrade, and I believe this should be addressed for all affected vehicles. I strongly urge NHTSA to investigate this issue and consider whether a recall or mandatory modification is warranted for the affected Tesla Model 3 vehicles. Please contact me if any additional details are required.

As we were normally driving, the car lost power immediately with no warning sign. After the power is lost, brake does not function, electrical door button doesn't function, hazard light doesn't function. Car was able to scroll to a complete stop to the side of the road. The steering wheel is locked. Again, BRAKE DID NOT FUNCTION after the power is lost. No button works, no screen turns on, car is not able to turn to neutral. There was no collision prior and no warning prior. Tried to file a police report. But Officer [XXX], badge # XXX, refused due to there was no collision and no accident.

BMS_a079 error. Battery is no longer able to charge. High voltage battery will need to be replaced. Basically rendering the vehicle useless unless the battery is replaced.

Vehicle's turn signal is not hardware based, but instead relies on the software registering signal use. The turn signal can be "fully" pressed, and "partially" pressed, and the behavior is supposed to be: Full press: Blinks until you manually disengage 1/2 press: Blinks 3 times, then automatically disengages. Anything "between" a full press and a half-press, ie beyond the level which is supposed to trigger a 3-time blink, but not "bottoming out" the signal, regularly fails to trigger the signal at all. This leads to scenarios in which the driver "thinks" they have signaled, and creates unsafe situations for surrounding vehicles.

The Tesla uses “auto high beam” when in autopilot. The pros of this can allow drivers to utilize the light so the cameras can detect anything to avoid any possible wrecks, but it does not have an option to be turned off. Along with other people online, my brights have flashed at people on the interstate and highways or haven’t turned off at all. This is irritating and limits the way I am comfortable with using autopilot. Please inform Tesla to make the auto high beam feature OPTIONAL.

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.

Correction: Retrofit SBR in OCS Equipped Front Passenger Seat - Remove and Replace. FIRST ROW - SEAT BELT REMINDER SENSOR BOX CLIP (1130363-00-B), FIRST ROW OCCUPANCY SENSOR(1099592-00-F) FIRST ROW SEAT HARNESS ASSEMBLY - RIGHT HAND (1489060- 03-G). This car has 69k miles and I'm informed this is out of warranty and has a cost of $696.75 to repair on a car that is less than 4 years old. Saying the sensor failed is not accurate as the error does not exist unless there is someone in the passenger seat which tells me the sensor is working somewhat. Tesla will not inform me of what will and will not work in the event of a collision but that these items need to be replaced to ensure safety of occupant's. I am skeptical since safety is your number one concern and should be the concern of every auto manufacturer. Unless damage by the owner specifically, how and why is this not covered for the life of the vehicle?

While driving a Tesla 2021 model 3 tonight at 8:45 P.M. turning left the wheels locked to the left and would not turn straight causing me to hit a concrete divider. After hitting concrete divider steering released to normal driving but driver side car front rim tire was damaged and wheel alignment misdirected.

While driving, I started to hear a creaking sound while backing up and turning the wheel left. The sound became worse over the course of a few weeks. The steering also felt a little loose. I reached out to the manufacturer for a service appointment, and could only be scheduled about a month out. After a few weeks, while trying to parallel park, the car felt like a tire was stuck, or had a flat. I stopped the car to look at all of the tires and they looked fine. When I returned home, I tried to recreate the issue with my wife moving the car slowly from the driver seat while I looked at the wheels. As she turned and backed up, the creaking sound was very loud, but the tires looked fine. When she put the car in drive and began to pull back into the driveway, I could see the front passenger tire was turned abnormally far to the left, looked like it was leaning, and it was locked (not rolling). Once we had the car in a safe position, I jacked up the car and looked at the passenger control arm to see a bolt completely missing from the front suspension lateral link. The other bolt was 1/2 of the way out and barely holding on. If this had come apart at highway speeds, I am afraid it could have killed or seriously injured my family.

I was driving to work that all of sudden heard warning sound and the monitor displayed the "Shutdown" sign as well. The car lost its power and came to complete stop in the middle of the street. Luckily there was no car near me. I was not able to drive the car and had to tow it to the dealership. According to mechanic “the rear drive unit has failed internally”. This was extremely scary and dangerous and may have caused a fatal accident. The problem has been fixed.

Driving south on the 5 freeway right northing on Oceanside the vehicle shut down at freeway speed. I had to coast of the to the first Oceanside. Fortunately it was late at night and there were no cars in the immediate vicinity. In addition to this the vehicle has had multiple episode of phantom breaking. I do not feel safe driving the car.

On [XXX], I was given a Tesla Model 3 loaner vehicle (VIN: [XXX] ) from the Knoxville, TN Tesla Service Center while my own Tesla was in for warranty repair. At pickup, I told the service advisor that the passenger-side tires looked unsafe. No inspection or warning was provided. After driving only 7.7 miles at normal speed on smooth roads, both passenger-side tires failed simultaneously. There were no potholes, curbs, or debris impacts. Tesla’s own service invoice states the cause was “not specified” and only speculates possible curb or debris damage without proof. Two tires failing on the same side so soon after hand-off suggests a pre-existing structural defect or safety issue. This incident posed a serious safety risk to myself and other motorists and could have caused loss of control at highway speeds.

Pirelli PZero 235/35/R20 tires on the entire car, was driving when front left tire blew out after 4500 miles, had the car towed back to Tesla dealer and tire replaced. Now after 2 months, rear left tire has bubble on the sidewall after only 5400 miles with no indication of previous damage. I believe this to be a defective tire and an immense safety hazard.
