Tesla Model 3 2020 — Problemas relatados

I own a 2020 Tesla Model 3 purchased in 2023 with Full Self-Driving (FSD) included for the lifetime of the car. I used FSD satisfactorily for years, but Tesla recently removed the maximum-speed control I previously used while FSD was engaged. I have personally experienced this change. FSD selects speed, but I can no longer impose the maximum I previously could set. I consider this a safety issue: unwanted speed requires the driver to detect it and intervene, potentially exposing occupants and other road users to excessive speed. The human driver remains responsible for safe, lawful operation and faces possible speeding tickets. I have read reports describing maximum-speed control as an "anti-pattern." I do not consider that an adequate safety justification for removing a preventive control. Learning a driver's preferences should operate within an explicit speed ceiling. I believe Tesla has the engineering capability to develop and validate a solution that preserves both FSD functionality and effective driver control. I request NHTSA investigate and require a remedy if a safety defect is established. My position is that affected FSD systems should not operate on public roads without an enforceable driver-selected maximum speed, independent of driving profile. Manual braking and disengagement remain necessary but do not replace this preventive safeguard. I welcome contact from Tesla and am willing to collaborate on a solution. My willingness to help does not diminish my request for restoration of this safety control. Contact details are provided separately in this complaint. Exact software version and change date: UNKNOWN. Dealer/service-center confirmation: UNKNOWN. Inspection by Tesla, police, an insurer, or others: UNKNOWN. Prior warning lamps/messages: UNKNOWN. Availability for inspection: UNKNOWN.

I am reporting a premature and severe multi-component front suspension failure on my 2020 Tesla Model 3 that poses a serious steering and control safety hazard. While driving and turning at low speeds (such as parking), the front end began emitting a loud mechanical clicking and popping sound. A certified technician diagnosed the vehicle and found that multiple critical suspension components had failed or worn prematurely at just 55,089 miles. The failures include the front lower lateral links, front lower compliance links, front upper control arms, stabilizer bar and front end hubs failing completely and simultaneously. This is a well-documented issue among 2018–2020 Model 3 vehicles and is currently the subject of an active NHTSA Preliminary Evaluation investigation regarding front lower lateral link detachment. Premature failure of these load-bearing suspension components compromises the vehicle’s structural integrity, accelerates extreme tire wear, and presents an immediate risk of component separation or sudden loss of steering control at high speeds. Tesla should issue a safety recall for these defective suspension components and compensate owners for out-of-pocket repairs.

I have a 2020 Tesla Model 3 with Full Self Driving (FSD) and am having trouble with "limited visibility" warnings daily on all cameras in direct sunlight since getting the V14 Lite software. I am aware that here is an NTSB investigation, EA26-002, that specifically raised concerns about Tesla's visibility-degradation detection software, including updates to that system. I have a 2020 Tesla Model 3 with old cameras using software for new, better by far, cameras. Tesla also acknowledges in its July 2026 investor materials that FSD v14 Lite transfers behavior developed for AI4 into the camera and computing configuration of AI3/HW3.

VEHICLE INFORMATION Make/Model/Year: Tesla Model 3 (2020) Component: Steering / Autonomous Control (ADAS) INCIDENT SUMMARY While driving on Autopilot/FSD southbound from [XXX], the vehicle experienced a sudden, uncommanded lateral steering excursion (phantom steering actuation) pulling abruptly toward the roadside shoulder. The driver had to immediately apply manual counter-steering torque to override the system and prevent a major collision. This unprompted steering correction caused the passenger side mirror structure to strike a roadside utility pole. KEY SAFETY FACTORS Sudden loss of directional control caused by computer-generated steering inputs rather than driver command or road obstruction. Quick driver intervention prevented a severe collision, but resulted in structural impact to the entire passenger mirror assembly. An official service ticket has been filed with the manufacturer requesting an immediate engineering telematics log pull (Steering Angle Sensor inputs vs. manual override torque, FSD state logs, and camera arrays) for the specific timestamp.

The steering assist reduced alert popped up on the tesla screen. While attempting to turn into a parking garage, a "steering assist reduced" alert suddenly appeared on the tesla screen, and the steering wheel locked up/became extremely heavy and unable to steer left or right. Because the steering assist failed in active traffic at the entrance, the vehicle was temporarily stranded, exposing to oncoming traffic and created an immediate risk. Failed component: electronic power-assisted steering (EPAs) rack and steering gear assembly. The failed component was replaced by Tesla and is not available for personal inspection. Safety risk: The sudden loss of steering ability in active traffic prevented normal maneuvering, forcing the vehicle into a hazardous position where passing vehicles could have collided with it. The issue was confirmed by Tesla Service, who performed a full steering rack replacement. The vehicle was inspected and repaired directly by the manufacturer (Tesla Service Center). There were no warning lights or symptoms prior to the incident; the failure and "steering assist reduced" error appeared abruptly during the turn.

Lower Lateral Link Fronts and front lower compliance link assembly for both right and left. There have apparently been on going issues for the Tesla Model 3 suspension links. I first started hearing noises from the suspension last month, I was booked for a weekend service and then rescheduled for today. I stopped by for a formal comprehensive inspection and was informed that there is tearing in the suspension. I already had this vehicle brought in for warranty earlier this year, how was this not brought up to me during that time frame? Did the suspension suddenly start tearing after 6 months?

I own a 2020 Tesla Model 3. Over approximately the past 2–3 weeks, the vehicle has developed a noticeable rattle/creaking noise coming from the left-front suspension area. The noise was not previously present and appears to be getting my attention as a potential suspension-related safety issue. I am concerned because my vehicle falls within the model-year range of Tesla Model 3 vehicles associated with reported front suspension/lateral-link issues. I understand NHTSA is investigating reports involving front suspension component failures that could potentially affect vehicle control. I contacted Tesla through the Tesla app and requested that the vehicle be inspected because of the suspension noise and my safety concern. Tesla provided an estimate requiring approximately $240 for diagnosis/inspection before determining the cause. At this time, I have not experienced a suspension separation, crash, injury, or loss of vehicle control. However, because the vehicle is producing a new and persistent noise from the left-front suspension area, I am concerned that this could be an early indication of a suspension component problem. I am submitting this complaint so NHTSA has a record of the symptoms on my vehicle and can determine whether they may be related to other reported front suspension failures. I am also requesting that this complaint be considered in connection with any ongoing investigation involving front suspension/lateral-link failures in 2020 Tesla Model 3 vehicles. I will retain Tesla service records and any inspection findings and can provide additional information if requested.

The contact owned a 2020 Tesla Model 3. The contact stated that while driving 50 MPH in traffic on a sunny day, the vehicle drove over a pothole, and the traction control and ABS warning lights illuminated. The brake pedal was checked; however, fifteen minutes later the vehicle crashed into a 26-foot box truck. The contact stated that the box truck left the scene of the crash. The tire skid marks were 100 feet long. The air bags failed to deploy. The contact stated there was an electrical failure which caused the brakes to become inoperable. Additionally, the alerts were late. The contact stated that the battery might need to be replaced. The driver and his daughter, who was seated inside the vehicle, sustained back pain, whiplash, and knee injuries. The driver was transported by ambulance. Medical attention was provided. The contact stated that surgery might be needed in the future. The daughter was taken to the hospital, and medical attention was provided. A Police report was filed. The vehicle was towed to an auto body shop. The EDR was requested on the manufacturer website. The failure mileage was approximately 119,730.

The contact owns a 2020 Tesla Model 3. The contact stated that while driving at an undisclosed speed, the safety features independently deactivated. The contact purchased and replaced the battery. The vehicle was taken to the dealer, where it was diagnosed with ECU failure. The contact was informed that the ECU needed to be replaced. The vehicle was not repaired. The contact stated that an unknown software update was completed in June 2026. In addition, the contact stated that the unknown software update caused the ECU to fail. The manufacturer was made aware of the failure, and a case was filed. The contact was informed that the failure was a known failure with similar vehicles. The failure mileage was approximately 80,000.

The front passenger door intermittently becomes “unclosed.” When this occurs, the vehicle displays “door open” and the passenger door window rolls down and up repeatedly. The window cycling continues until the door is slammed firmly shut. Once the door is securely shut, the window cycling stops and the door-open warning clears. When it occurs: The issue began in the second week of August while a passenger was in the front seat. It continued while the passenger remained seated. The issue occurs intermittently while the vehicle is moving, including when the vehicle goes around a curve.

I was told my car is unsafe to drive after taking it to the mechanic for a routine tire balance and rotation. I currently need both rear control arms replaced. I had them replaced in the past. In addition, I have had the front control arms replaced more than once, the lower lateral links replaced, numerous hubs repaired, forelinks and knuckles all replaced not too long ago, so this news comes as a shock. The first control arm failure occurred when the car was only a year and a half old with very little milage. I have all of the service records in my tesla app vehicle repair history. They are in a pdf format and I would be happy to send them in, if helpful.

I was operating my Tesla with Full Self-Driving (FSD) engaged when the incident occurred. I was turning right onto [XXX] from [XXX] and was positioned in the left right-turn lane approaching a railroad crossing. The railroad crossing gates were already fully lowered, indicating an approaching train. Despite the lowered crossing gates, the vehicle accelerated forward into the crossing rather than stopping. The vehicle drove through the lowered crossing gate, which struck and shattered the windshield. Seconds later, the train passed through the intersection. I did not command the vehicle to proceed through the lowered gates. The incident resulted in significant damage to the windshield and raised serious safety concerns because the vehicle entered an active railroad crossing immediately before the train arrived. The vehicle was towed to a Tesla Service Center due to the damage. Fortunately, no collision with the train occurred and there were no injuries, but the incident had the potential to result in catastrophic injury or death.

All Teslas vehicles running HW3 / AI3 Autopilot self driving computers have been known for years to have a defective design problem with the cooling system without its own dedicated cooling and which puts the self driving computer last in the cooling looping at the top of the cooling stack. When the computer fails and they will Tesla requires the owner to replace the computer. This does not result in a redesigned improvement to the computer or cooling system that reduces the thermal stress being applied to the new computer. Tesla is now pushing a new version of the self driving FSD software with the “v14 Lite” release over the last two weeks. This software release uses large complex software models which Tesla design to use every part of the HW4 / AI3 compute power which stressed the computer by pushing it to it compute limiting. All this compute is causing the computer to overheat and fail. Tesla then require owners who are all out of warranty now to pay thousands to replace the computer. This replacemen uses the same flawed cooling system and the same computer incapable of dealing passive compute requests on it by the latest v14 Lite software to eventually cause the computer to just require the replacement computer to eventually need yet another replacement of the same flawed design at owners cost. There is also supposed to systems which monitor the thermal stress on the computer and shut it off abruptly until it cools down which is not ideal at freeway speeds which is not happening. Recall to address and resolve the issue with improved cooling, more powerful computer that doesn’t reach maximum capacity and it’s each use, and less taxing software needs to be issue. This is a major safety design problem which Tesla has not addressed. There only solution is to just replace design constrained components with the exact same parts at owners cost. These multiple design issues can and often result is sudden shutdown of the computer, or worse case sudden complete failure.

I own a Tesla Model 3 and have been experiencing concerning front suspension and steering issues that appear to be worsening over time. While driving and especially during low speed turns, parking and maneuvering, the front suspension produces loud screeching, squeaking, and rubbing noises. The steering has also become noticeably stiffer that normal at times, and the noises can be felt through the steering wheel. The sounds are coming from the front suspension area and occur repeatedly during normal driving. The issues raises significant safety concerns because I am worried there may be a defect affecting the front suspension of steering components. Unexpected steering resistance combined with loud suspension noises creates concern that a suspension component could fail while the vehicle is in motion, potentially resulting in loss of steering control or a crash. There were no warning lights or messages displayed before or during these symptoms. The vehicle has not been involved in any collision that would explain these symptoms. The problem has continued during normal operation and appears to be getting progressively worse. The vehicle is available for inspection upon request. I am submitting this complaint because I understand NHTSA is investigating front suspension issues involving 2018-2020 Tesla Model 3 vehicles, and my vehicle is experiencing similar symptoms. I believe this issue should be investigated to determine whether it is related to the front suspension components under investigation.

The front upper control arms. Causing poor steering and unbearable loud creaks when turning wheel. Mobile tesla tech confirmed upper control arm

Component that failed was the lower lateral link. There was no loss of control but there was a sound going over any uneven surface. Upon bringing the vehicle to the Tesla dealership they recommended a replacement of the upper and lower control arm on both the driver and passenger side. This greatly increased the cost of the repair to a total of $2356.84

Suspension is grinding. I had it replaced once at Tesla and it began grinding again in less than 18 months. I took it to Tesla and was informed the lower control arm failed and the price had more than doubled from the prior replacement. No warning lights have come on regarding this issue. The original replacement was 3/7/2024. I noticed the grinding between 12-18 months later. Also, the rear brake light gets condensation in it somehow. I had noticed this about 1 year ago.

In Jan, 2026, the front suspension in the 2020 Model 3 started making a cracking, catching, grinding and/or popping noise as I turned the steering column while parked or driving slowly. When investigating, it sounded like it was coming from bearings in the front suspension. It continued to get worse, making the catching / grinding / popping noise when driving on the highway, turning or not turning, to the point that it felt like the suspension would completely tear apart, and I took the vehicle in for service in early March. Telsa service ended up replacing the left and right upper control arm assembly, the front left and right lower compliance link and the lower lateral links. Online research on various tesla forums showed this to be a known problem with vehicle owners. Unsure if continuing with the issue prior to service would have caused a safety concren, but it was beyond the point of sounding safe to operate to me.

I was making a right turn from the parking lot onto the street, a maneuver I have made hundreds of times previously without any issue. My foot was on the accelerator pedal as normal for this turn. The vehicle accelerated far faster than intended for this maneuver, with tires screeching, and continued across the width of the street. The vehicle's front left wheel struck the curb on the opposite side of the street from the parking lot exit. The wheel sustained significant damage, and the wheel rim was torn. When I regained my bearings, I lifted my foot off the accelerator and the vehicle slowed down. At the time, I believed a serious crash was imminent. I was able to drive the vehicle home, which was about 1 1/2 miles away, but it is not safe to drive so I won't drive it until it is repaired. I am aware that Tesla and NHTSA have attributed many prior sudden acceleration incidents to drivers unintentionally pressing the accelerator when intending to press the brake. Due to the vehicle's regenerative braking, I rarely use the brake pedal during normal driving, which makes this explanation virtually impossible in my case. I am also aware that NHTSA reopened an investigation in 2023 after learning about a potential inverter-related design flaw that could cause sudden unintended acceleration in Tesla vehicles, and that this investigation remains open as of this writing.

On XXX, at approximately 2:47:42 PM, I was driving a 2020 Tesla Model 3 Long Range AWD VIN [XXX] on a two-lane road in the Adirondacks with Full Self-Driving (Supervised) active. The vehicle was traveling approximately 50–52 mph. An oncoming SUV moved toward or across the double-yellow centerline while passing a bicyclist. FSD reacted with a sudden and aggressive steering maneuver to the right. The vehicle crossed the white edge line and entered the paved shoulder. Because it appeared that the vehicle might leave the roadway, I immediately took control and steered it back toward the travel lane. The vehicle then oscillated sharply in both directions before stabilizing. External telemetry shows lateral acceleration reaching approximately 0.88 g in one direction and 0.84 g in the opposite direction, with a 1.72 g peak-to-peak lateral swing. Vehicle speed fell from approximately 50 mph to approximately 28 mph during the recovery. No collision or injury occurred. The rapid deceleration and stabilization appeared consistent with possible electronic stability-control intervention, but I cannot confirm that from the available external telemetry. I have preserved the front dashcam video and telemetry file. I request that Tesla preserve and review the internal vehicle logs, including FSD commanded steering, planned path, driver steering torque, road-edge perception, oncoming-vehicle perception, stability-control activation, individual-wheel braking, and motor-torque reduction.

Car was sitting at a red light while in Full Self Driving (supervised). The screen showed at least four red lights. Suddenly the car started to move forward while the lights were still red. I was able to stop it from going further. This has happened before and I reported it then. If I had not had my foot near the brake pedal the car might have just run through the light.

On July 11 at approximately 6:47 a.m., I was operating my Tesla Model 3 on Interstate 65 in Hart County, Kentucky, with Full Self-Driving (FSD) engaged during normal highway travel. Approximately one hour earlier, I had departed a highway rest area after sleeping from the previous day’s travel. Rain developed during the trip, but I observed adequate visibility, apparent roadway traction, and I was not impaired. I was traveling in the far-right lane of a three-lane interstate. The posted speed limit was approximately 70 mph; however, FSD limited the vehicle to approximately 65 mph and displayed warnings indicating that the higher speed was unavailable. While FSD remained engaged, the system initiated a lane change from the far-right lane into the center lane. After entering the center lane, the vehicle began displaying repeated warning messages and FSD disengaged multiple times. I attempted to locate settings related to the warnings on the touchscreen but could not identify an available adjustment. During the third disengagement, I perceived that the vehicle continued braking without releasing while steering resistance increased significantly. The steering wheel then rotated abruptly, and I was unable to regain normal directional control before the vehicle departed its intended travel path and struck a concrete median. The collision caused personal injuries and substantial vehicle damage. I have not been able to reproduce the condition. The incident was investigated by the Kentucky State Police. Based on the sequence of repeated FSD warnings, disengagements, continued braking, and abrupt steering behavior, I believe this event warrants investigation. I request that NHTSA review the vehicle’s Full Self-Driving logs, telemetry, Event Data Recorder (EDR) data, steering and braking commands, diagnostic records, and software history to determine whether a vehicle or software malfunction contributed to the collision.

On XXX at approximately 5:00 PM, I was driving my 2020 Tesla Model 3 on [XXX] from [XXX] toward [XXX], with Tesla FSD engaged. Near the area where the center divider begins/ends, the vehicle crossed the double yellow/divider area and entered the opposing traffic lane. There was no oncoming traffic at that moment, so there was no crash, but this created a serious potential head-on collision risk. The car also did several hard jerks that aggravated my neck and back that it has been consistently doing for a long time which cause worse ongoing headaches. The system/component that malfunctioned was Tesla FSD/Advanced Driver Assistance, including lane keeping/steering behavior. The vehicle is available for inspection upon request. My safety and the safety of others were put at risk because the vehicle moved into the lane for oncoming traffic. I had to intervene and no longer feel safe using FSD. I have reported unsafe FSD behavior to Tesla multiple times before, but the issue has not been resolved. Tesla service has previously listed the concern as “FSD not working properly/test drive required” and/or general diagnosis, but I have not received a clear written resolution explaining why the vehicle crossed into the opposing lane or how Tesla will prevent this from happening again. There were no warning lamps or messages that I recall before the vehicle crossed into the opposing lane. If Tesla has vehicle logs or telemetry for the incident, I request that they be reviewed. I am reporting this because the vehicle may repeat this unsafe behavior and create a head-on collision risk. The car continues to behave unsafely and erratically. i have a log of some of the incidents. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The wiring in my trunk harness was severed due to the repeated opening and closing of my trunk. This caused my reverse lights to fail and my trunk latch to stop working. This issue is part of a known recall: Campaign 21V-00D. Tesla attempted to fix the issue in 2023 but the poor repair did not work. I took my Tesla to the dealer and they refused to remedy the issue unless I would pay $1300. I persuaded them to lower the feet to $300 but still feel that I should not pay anything because this issue was due to the recall.

The contact owns a 2020 Tesla Model 3. The contact stated that while driving at an undisclosed speed, there was a clinking sound coming from the front of vehicle. No warning lights were illuminated. The contact stated that the dealer was contacted, and a repair was pending on the lower lateral link. The contact stated that the VIN was not included in NHTSA Campaign Number: 21V835000 (Suspension). The contact associated the failure with the recall. The manufacturer was not made aware of the failure. The failure mileage was approximately 40,000.

Subject: Tesla HW2 FSD – Advertised Safety/Autonomy Features Not Provided Description: I am reporting an issue regarding my 2020 Tesla Model 3 equipped with Hardware 2 (HW2) and Full Self-Driving (FSD) package. Although the vehicle is listed and sold as “FSD capable,” Tesla has stopped providing FSD software updates for HW2 vehicles. My vehicle is stuck on FSD version 12.6.4 and cannot receive newer versions (v12.7, v12.8, v13, etc.). Tesla continues to advertise FSD as an evolving safety and autonomy system, but HW2 vehicles are no longer receiving the required updates to maintain or improve safety functions. This results in: • Safety-related features not being updated • Autonomy features advertised at purchase not being delivered • OTA updates being discontinued without notice • Tesla refusing to provide a hardware upgrade path (HW3) despite FSD being purchased on this VIN This creates a safety concern because the vehicle is operating with outdated perception and driving models while newer vehicles receive critical improvements. Tesla has not provided a remedy, timeline, or alternative solution. I request NHTSA to investigate Tesla’s failure to provide advertised and safety‑related FSD functionality for HW2 vehicles. Vehicle Info: 2020 Tesla Model 3 Hardware: HW2 FSD purchased on VIN (previous owner) Purchased used in July 2023 Current FSD version: 12.6.4 (no further updates)

This was not an incident. Instead I’d like to report it as a design flaw. I discovered low speed noise and got it fixed at Tesla service center. Upper control arms and lower control links have both been replaced at ~70k miles and the cost to repair was over $2k at Tesla service center in Feb 2026. Later in May 2026 Tesla published a service bulletin acknowledging this is a design flaw

The screen (which controls all functions of the vehicle) starts to go haywire. It's almost like there is a phantom touching the screen and pressing buttons. The screen will start zooming in and out - changing your navigation destination. The air controls will turn on full blast and then you are unable to shut them off because the screen will not respond. It becomes a giant distraction to the driver (imagine a screen that large malfunctioning) and tesla does not think this is a safety issue. We reported it to them. They couldn't replicate the issue (is what they told us and then let us know it was out of warranty and we could just replace the screen to a tune of almost $2000). There are no cracks or issues with the screen itself. I cannot upload the videos as they are too big to share but I can send them to an email address.

Tesla was on Full Self Driving following a curve in the road were traffic lights. Lights were red Car should have stopped but did not. Ran red light with no attempt to stop or slow down.

The contact owns a 2020 Tesla Model 3. The contact stated that while driving at various speeds, the vehicle made an abnormal clunking sound while turning the steering wheel. The messages "Traction Control Disabled", "Lane Departure Avoidance Feature Disabled", "Automatic Vehicle Hold Disabled" and "Stability Control Disabled" were displayed. The vehicle was taken to a dealer, where it was discovered that the lateral link was not attached to the control arm due to a defective bolt. The contact was informed that the subframe and the front passenger’s side lower control arm needed to be replaced. The contact related the failure to NHTSA Campaign Number: 21V835000 (Suspension); however, the VIN was not included in the recall. The vehicle remained with the dealer unrepaired. The failure mileage was 46,124.

Driving S/B on Ann Arbor Saline Road. Had FSD on the Tesla engaged. Needed to make left turn onto Maple. Left arrow light to Maple was red.

2020 Tesla Model 3 Standard Range Plus, VIN [XXX] restraint control module fault codes RCM_a056 and RCM_a058. Passenger front seat occupancy sensor failure triggering "Service Required" airbag system alert. September 2024: fault code RCM a056: Tesla repaired this issue under the Supplemental Restraint System Limited Warranty (5 years, 60,000 miles) at Tesla Service Latham NY (326 Old Niskayuna Rd, Latham NY 12110). January 10, 2026: Fault code RCM_a058. Reported in writing through the Tesla app. Tesla scheduled a service visit for January 13, 2026. Technician assessed the vehicle in person and declined to repair, verbally stating the fault may be a one-time occurrence and to monitor and return if it continued. April 2026: Fault continues recurring. Tesla Service Latham issued estimate #XXX dated April 18, 2026 for $1,076.32 customer pay. Repairs include resistive occupancy sensor replacement and seat back trim cover replacement. This is a safety-critical system governing airbag deployment. Tesla has documented this failure mode in internal service bulletins citing electrical interference in the seat harness as a design issue. Tesla repaired this under warranty, dismissed a related restraint fault for the same seat when reported within months of the repair, and is now billing the owner for a safety system that failed due to a known design defect. A recall is warranted.

Both front wheel and rear rims cracked under normal driving conditions. This is the third occurrence of rim failure on this vehicle. The most recent incident occurred in Ewing, NJ near Parkside Ave and Hillcrest Ave. There was no significant impact or major pothole at the time of failure. Multiple wheel failures indicate a potential structural durability issue. Cracked rims pose a serious safety risk due to the possibility of sudden tire pressure loss or blowout while driving. The vehicle has been operated under normal road conditions, and this repeated failure should not occur. The damaged wheels are available for inspection upon request.

My wife was cleaning the interior and wiped the center main display of her model 3. While doing that somehow she managed to Turn the heat on set the fan/temp controls to HI and popped the front frunk to open. When she exited and closed all doors, it looks like the heat kept running at max for more than 24 hours in the garage. When I entered the garage it was hot in there and inside temp of the car was at 87f. Not sure if there was a fire hazard due to heaters over heat. Just wanted to bring this to your attention.

The touch-screen only media center has an off-by-one error when using the media player for USB media. This results in unsafe conditions for the driver where the expectation of pressing "S" would navigate to music starting with "S", but instead navigates to music starting with "T". This creates momentary confusion for the driver, and pulls focus from the road. There is no mechanism to scroll through the music using non-touch related functionality. There is no warning to only use the media feature when stopped/parked. The manufacturer has acknowledged the issue, but refuses to provide any diagnostics or solutions without taking a downpayment for service.

My Tesla Model 3 was brought to Tesla Princeton Service Center on February 27, 2025 for a 12V battery replacement. During the service visit, Tesla also replaced the rear glass, citing the rear defroster as the root cause of the battery drain — a repair that was added without prior discussion and increased the total invoice from an original estimate of $180 to a final charge of $1,730. Upon picking up the vehicle, the rear backup camera, blind spot cameras, navigation system, Sentry Mode, and windshield wiper sensor were all non-functional. None of these systems showed any malfunction prior to the service visit. Tesla Princeton’s service advisor denied responsibility without performing diagnostics, and in a subsequent message admitted he could not determine the cause with certainty without diagnostics — which have still not been performed. The vehicle was discharged from a licensed Tesla Service Center in a condition non-compliant with FMVSS 111. I have escalated this matter to Tesla executive leadership in writing and am filing this NHTSA complaint to create a federal record of this safety violation.

When adaptive cruise control is enabled (Autopilot, not equipped with Full Self Driving) car will sometimes brake hard as if there is an obstacle ahead, with the words "Curve Assist Active" flashing on the screen. Seems to happen most often on state highways, vs interstate. In one case last night car slowed from 65mph to 30mph, on a straight road, with no object ahead. Thankfully no cars were immediately behind or I would have been rear-ended. Happened 4 times in 500 miles of highway travel.

Issue 1: While using Full Self-Driving (Supervised) at night on a two-lane road with a straight lane and a turn lane, the vehicle crossed the white lane markings and drifted into the adjacent lane. I had to manually intervene to correct many times. This happens regulary at night. I clean the lenses on the cameras but it doesn't reslove the issue. Issue 2: While using Full Self-Driving (Supervised), the vehicle positioned itself in the incorrect lane when entering a roundabout, selecting the wrong entry lane for my intended exit. This happens at day and night about 50% of the time. I report the issue via the Tesla feedback, but they do not fix it.

Sunday [XXX] downtown Sacramento, driving about 25 mph. Heard a loud bang—bolt sheared off front subframe. Steering felt lagging upon making a right turn vehicle proceeded in a very wide turn, pulled into parking lot. Wheel locked right as I exited [XXX] parking spot; steering went slack, brakes scraped rotor. Two witnesses saw hardware hit pavement. AAA tech removed tire: lower control arm bolt missing, no Loctite, subframe raw. Second bolt loose—single point of failure. Tesla missed this on six different service visits and during their one-twenty inspection before delivery. Recall 21V835 should’ve flagged it but service personnel assured me all clear on every visit . Vehicle towed to Tesla service center at 1104 Tinker rd, Rocklin, CA. Tesla shop manager Sal confirmed this failure as manufacturers defect, and poor assembly. Safety was seconds from total loss. Need probe.

Incident Date: Feb 1, 2026, 2:45 PM PST Location: Camarillo, CA (Pleasant Valley Rd & Village Commons Blvd) Description: The vehicle (Tesla Model 3, FSD Supervised) attempted an unprotected left turn. The system identified a gap but paused excessively before initiating the maneuver. After the pause—when the gap was no longer safe—the system proceeded to turn anyway, directly into the path of a speeding oncoming vehicle. The system failed to abort the maneuver after its own hesitation. It also failed to accelerate with the urgency required to clear the path. I was forced to manually override with emergency acceleration and steering into an oncoming lane to avoid a high-speed T-bone collision. This appears to be a "stale data" failure where the car executed an old plan that was no longer valid.

The front suspension control arms on my 2020 Tesla Model 3 are squeaking and show premature wear. The noise occurs during normal driving and is accompanied by clunking, which concerns me about potential control arm failure and loss of vehicle control. My vehicle is only 40k miles and it’s a very common issue that Tesla gets to make money on. Kind of funny it happens to everyone right when the warranty ends. I am aware that this is a known issue affecting multiple Model 3 vehicles. Despite proper maintenance, the problem persists and may present a safety risk. I request that this be officially recorded as a safety complaint.

Vehicle made thunking noise when driving over uneven surfaces such as bumpy roads, speed bumps, or railroad tracks. Diagnosis at Tesla service center showed front upper control arms assemblies (left and right), lower lateral link, and front lower compliance link (left and right) required replacement. Of note: upper control arm assemblies were previously replaced under warranty in November 2021 at 28000 miles. This short interval indicates defective suspension components leading to cascading failures putting driver safety at risk.

Vehicle Information: 2020 Tesla Model 3 AWD (Leased) Full Self-Driving (FSD) enabled Summary of Safety Issue: While Full Self-Driving (FSD) was engaged, the vehicle failed to detect roadside infrastructure and collided with multiple fixed objects, including a route sign board, a walkway sign board, and an underground electrical cable. The system did not provide adequate warnings or corrective action before impact. System jerk the steering confirmed system is engaged but did not break and drive to non-drivable area and not given any disengagement warning and totaled the car. Incident Details: • Date of incident: [XXX] • Location: On [XXX] {XXX] Piscataway, NJ 08854 • Road type: [XXX] • Weather/visibility: Clear • Speed at time of incident: <40 MPH (under the speed limit) Description: As soon as i trigger the FSD it immediately tried to navigated left or right and failed and unexpectedly veered into roadside infrastructure. The system did not slow down, steer away, or alert the driver in time to prevent the collision. The impact caused significant damage to public property and the vehicle is totaled. No injuries occurred. Evidence Available: • Photos of the scene and damage • Police report (number: [XXX] • Tow documentation • Tesla collision center estimate Reason for Reporting: This incident suggests a potential safety defect in Tesla’s FSD system related to object detection, path planning, and collision avoidance. The failure occurred without driver input and raises concerns about the system’s reliability in detecting fixed roadside objects. I request that NHTSA review this incident as part of ongoing evaluations of Tesla’s driver-assistance systems.
