ELECTRICAL SYSTEM

The main vehicle computer (MCU) failed. The problem first appeared in May 2024 with intermittent rear camera malfunctions. It has since worsened. Most recently (08/28/25), the center display went completely black and the vehicle became inoperable — I could not start or move it. This left me stranded in a dangerous neighborhood late at night and required the car to be towed. When the display fails, I lose access to the rear camera, climate controls (including defrost), and turn signal indicators. These are safety-critical systems, and in this case the failure also disabled the ability to drive the vehicle entirely. The problem has been reported to Tesla. They inspected the vehicle but claimed the earlier camera malfunction was unrelated to the current computer failure. No independent mechanic has inspected it. The failures are ongoing and reproducible. No warning lights or alerts appeared before the system shut down. The vehicle is available for inspection upon request. Being that this issue originally arose back in May, 2024- it should fall under Tesla’s warranty which expired in December 2024.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

Immediately after an over-the-air (OTA) update on Aug 8, 2025, my vehicle began showing camera connection errors and disabled multiple safety/ADAS features. Over the following days, I repeatedly received alerts that AEB was unavailable. The vehicle remained drivable, but AEB and related safety functions were inactive. Chronology: Aug 8, 2025: OTA software update to 2025.26.6 completed. Right after completion, the touchscreen displayed camera connection errors and disabled AEB / Autopilot / cruise control. Aug 11, 2025: While driving, I again received an “AEB unavailable” alert. Similar alerts appeared intermittently throughout the week. There was no water intrusion, impact, or external damage. Cameras were clean and unobstructed. I scheduled the earliest available Tesla Service appointment and reported the AEB failure as a safety issue. Service diagnosis: Tesla diagnosed a failure of the Autopilot computer (HW3) and ordered a replacement. Cost/coverage: I requested that the repair be covered by Tesla because the failure started immediately after the OTA update and I am a paid Full Self-Driving (FSD) purchaser. My request was denied; I was charged ~$1,600 (slightly discounted) for the computer replacement. Safety risk description: The failure disabled AEB and other forward-collision mitigation features without an external cause, beginning minutes after the OTA update. I consider this a safety defect because an advertised crash-mitigation system became unavailable during normal use, increasing crash risk. The timing suggests a possible software–hardware interaction (software change triggering or revealing a hardware fault) that could affect other vehicles.

POWER TRAIN

Summary of Issue: The vehicle has experienced intermittent drive disconnections without warning. This occurred multiple times on August 9–10, 2025, during trips between Palo Alto and Monterey. The vehicle is available for inspection upon request. What component or system failed or malfunctioned, and is it available for inspection? The suspected component is the drive unit (covered under Tesla’s 8-year Drive Unit & Battery warranty). The vehicle and its systems remain available for inspection by NHTSA or Tesla. How was safety put at risk? The intermittent drive disconnections can result in sudden loss of propulsion without warning while the car is in motion. If this occurs at highway speeds, it creates a serious safety risk of collision or loss of vehicle control. Has the problem been reproduced or confirmed by a dealer or service center? Tesla Service has attempted to inspect the vehicle but reported “no fault found.” Because the issue is intermittent, Tesla did not reproduce it during their inspection, though I documented it on August 9–10, 2025. Has the vehicle/component been inspected by the manufacturer or others? Yes, the Tesla Service Center inspected the vehicle 25 August 2025. However, Tesla has refused to provide a detailed record of what diagnostic steps were actually performed (log review, physical inspection, or drive unit stress testing). Were there any warning lamps, messages, or other symptoms? No warning lamps or messages appeared at the time of the failures. The vehicle resumed propulsion after several seconds, clearing the condition without leaving an active customer-facing alert. Concern: Because the failure is intermittent and leaves no persistent alerts, Tesla has returned the vehicle without resolving the problem or providing adequate documentation. This leaves a potential safety-critical drivetrain failure unaddressed. Requested Action: I request that NHTSA investigate potential drive unit intermittent disconnection failures in Tesla Model Y

SEAT BELTS

I have an alert that says Front Passenger Safety Restraint System Issue and Service is required. This is a major safety issue and the Tesla Service Center says I need to pay $800 to fix it. This is a manufacturer issue and the cost should not be incurred by the vehicle owner. This issue puts my family safety at risk and the light is coming up everytime I drive. I need TESLA to review it and fix this at no cost.

UNKNOWN OR OTHER

Brake line failed at the left rear tire. Corroded line. The line is corroded on the right rear also. These are my observations. The brakes failed when driving locally at lower speeds so the car was able to eventually stop due to the regenerative braking. Will be towed to the dealer for inspection/repair. Inspection/repair will occur on Sept.15, 2025. No warning until after the failure.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

The GPS and camera functionality went out on the same day several days ago. The car thinks it is at Tesla’s headquarters in CA and so you cannot find a charging station near your actual location, and no cameras work meaning the additional safety features for collisions do not function at all. This is a widespread issue based on Tesla user forums.

STEERING

The power steering became reduced and diminished while driving. Tesla is stating that there is corrosion on the wiring harness ports on the power steering rack. There was no warning until after the incident, but now a “reduced power steering” annunciation appears in the screen. The Tesla repair station has confirmed the condition.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

All cameras went blank on vehicle 4 year and 7 months old. All driver assistance systems became suddenly disabled. Tesla service diagnosis established that computer needs to be replaced for a cost of $2,000.

STEERING

The vehicle lost steering at 10 mph as a bolt from the front suspension's upper control arm and lateral link fasteners became loose and detached rom the vehicle. The wheel was completely misaligned, and the vehicle was not drivable. The vehicle could not be moved to the side of the road, putting my safety and the safety of other drivers at risk. I fear that this could have been a fatal accident had I been on the highway. This issue has been confirmed by Tesla Service Center, and they acknowledged that this is a known issue. There were no warning indicators or recall notices sent to warn of this known issue. My vehicle should have been recalled. Tesla is making me pay $3,000 for repairs despite knowing this is a manufacturer defect, and they are continuing to put lives at risk by not issuing a wider recall.

Vehicle: 2021 Tesla Model Y VIN: [XXX] Date of Incident: [XXX] On the afternoon of Sunday [XXX], while my Tesla Model Y was parked at home and charged to approximately 80%, both my wife and I attempted to enter the vehicle to attend an important appointment. Upon approach, we found the car completely unresponsive — no power, no screen activity, and we were unable to start the vehicle or release the charging cable. Despite this, both front doors could still be manually opened. However, the frameless windows did not automatically lower as they normally would when opening and closing the doors, As a result, when we attempted to close the doors, both front door windows shattered, as the glass was unable to lower and collided with the door frame. This incident clearly resulted from a critical system failure that disabled essential safety and design functions. The vehicle was not damaged prior to this event, and there was no impact or external force involved. This malfunction rendered the vehicle inoperable and directly caused costly damage. I am requesting the following: A full investigation into the root cause of the power system failure Immediate replacement of both shattered front windows at no cost A written explanation of what caused the vehicle to become unresponsive This issue raises serious concerns about vehicle safety and reliability, especially when essential functions like glass auto-drop are disabled without any warning, leaving the glass vulnerable to breakage.

STEERING

My 2021 Tesla Model Y experienced a sudden loss of steering assist, resulting in an extremely heavy steering and loss of steering ability, at highway speed. I needed extreme efforts to push the steering wheel to go off highway to avoid accident. This happened on 6/14/2025 around 3PM. Tesla service diagnosed "internal electrical/mechanical steering rack failure", but no recall was issued for my VIN. I've reviewed NHTSA Recall SB-25-00-004 (2025) for 2023 Model Y involving EPAS/steering assist failure. The symptoms in my car appear identical. I believe the issue may affect more model years than the recall currently covers and request HNTSA investigate further.

I WAS DRIVING ON AN INTESTATE HWY I-70 EAST BOUND ON THE LEFT LANE AND I WAS ABOUT TO TAKE THE EXIST 62. I WAS ON CRUISE CONTROL AND IT WAS RAINING AND THE ROAD WAS WET. WHEN I TRIED TO CHANGE THE LANE THE CAR AUTO BRAKED AND CAR SKID AND ROTATED 360 DEGREES AND HIT THE RAILING. THE CAR GOT DAMAGED FRONT AND BACK. LUCKILY THERE WAS NO VEHICLE NEAR US SO MY FAMILY WAS SAFE. BUT I DONT KNOW WHY THE CAR AUTO BRAKED AND ONE SHOULD NOT HARD BRAKE WHEN THE ROAD IS WET. I CALLED 911 AND TESLA INSURANCE. I TOOK THE CAR TO THE BODY SHOP AND THEY ARE DEEMING IT TOTAL LOSS. PLEASE TAKE NECESSARY ACTIONS SO IT DOESNOT HAPPEN AGAIN

“Front passenger Safety restraint system fault, service required” RCM2_a636 message keeps appearing on the screen. It happened right after I bought the car, so I took it to Tesla to fix. It went away for a few months and now it’s back again. According to Tesla, this fault, “ Based on the airbag system's self-diagnostic checks, a persistent fault has been detected in one or more safety restraint components. This could involve seat belts, impact sensors, occupant sensors, or related safety components. • If the airbag warning indicator stays on, the vehicle should not be driven until inspected. • Recurring faults require immediate Tesla service attention. • Pre-tensioner or sensor damage can compromise proper seat belt functionality.” This is a serious safety issue that should be addressed in a recall as it could jeopardize occupant safety of the seat belts or air bags do not work. It also appears to be somewhat widespread and persistent. Tesla also does not appear to have a permanent fix as the first time I took it in they made a comment about one repair already having been done on this before I got the car as a certified used one from Tesla.

I was driving slowly at a parking lot of a supermarket and preparing to park on my right. When I saw a car on my left front backing up, I pressed on the brake pedal immediately and turned the wheel slightly to the right. All of a sudden, the Tesla accelerated on its own with a very strong force and high speed, with the wheel turned sharply on its own toward the right. The Tesla then run through the steel fence of the parking lot, flying past the sidewalk, and finally settled on top of a big rock on the ground (which is placed there to protect the supermarket building). All of these happened so fast with such a strong force and all in an unintended manner. I was not injured and luckily no other persons or vehicles were involved. However, the vehicle was totalled and there were damage of the supermarket property.

SUSPENSION

Upper and lower control arms failed, and front suspensions bushings became torn. The car did not present any warning lamps or warning messages. The issue became apparent when a loud creaking/squeaking sound started coming from the front of the vehicle, and could be reproduced by turning the steering wheel, or by accelerating or braking. Control arm and suspension failures have been a frequent issue amongst Tesla owners, and the NHTSA should consider a recall for the design flaw.

TIRES

 A little background information, on Dec 2023 I installed 4 new Hankook Ion Evo AS (255/45R19) for my Tesla model Y at the Correa Tire shop in Dorado Puerto Rico and the manufacture date on those tires was 4422 and at the time the car had close to 30k miles.  On April 2025 one of the tires broke and I replaced it at the same place with the same tire model.  Less than a month after the new tire was installed, while riding on the highway at close to 65mph the recently replaced tire completely broke off leaving only the sides and the rest of the tire flew off the car (see pictures attached).  This happened suddenly with no previous indication or car notification of any issue with the tire.  Fortunately, I was able to stop the car without losing control and apparently the tire did not hit other oncoming cars.  This was a very scary situation, which could have resulted on a serous and even fatal accident.  When I checked the new tire, or what remained of it, I noticed it had the same manufacturing date (4422) as the tires I had replaced in 2023. The next day I went to the tire shop and explained the incident and they informed I had to buy a new tire while they investigated the situation and if there was any issue with the tire. At that time I also opened a complaint with Hankook US. After waiting various weeks for a response, and expecting reimbursement for the damage tire, I have not received any information from the tire shop and Hankook said they did not receive a claim from the tire shop.

LATCHES/LOCKS/LINKAGES:DOORS:LATCH

1. What component or system failed or malfunctioned, and is it available for inspection upon request? The 12V battery failed unexpectedly, causing a complete shutdown of the vehicle. The car became fully inoperable—doors, windows, touchscreen, and manual override systems were unresponsive. Yes, the vehicle is available for inspection. 2. How was your safety or the safety of others put at risk? My young child was inside the car at the time of the failure. Due to the system lockout, I was unable to open the doors or remove them from the vehicle. Emergency responders were called and had to break windows to safely extract my child. This situation posed a serious risk of heat exposure, panic, and injury. 3. Has the problem been reproduced or confirmed by a dealer or independent service center? The failure has been documented and attributed to a dead 12V battery, though Tesla has not formally inspected the vehicle as of this writing. I am working to have it evaluated by a qualified technician to confirm the cause. 4. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives, or others? The vehicle was not inspected by Tesla at the time of the incident. Emergency responders did assess the situation on site. I plan to notify my insurance provider, and will make the vehicle available for inspection. 5. Were there any warning lamps, messages, or other symptoms of the problem prior to the failure, and when did they first appear? No. There were no alerts, notifications, or warning lights indicating the 12V battery was low or nearing failure. The malfunction occurred without warning.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

- Computer appears to stop working in colder temperatures (or random). - ALL cameras, including rear view camera (needed for backing up) and side cameras stop working. Error message shown on touch screen saying cameras are not available. - All road sensing information including other cars, lanes markers (everything) disappears from touch screen dashboard and no longer works. There are no longer any warnings for anything. - GPS tracking stops and no longer tracks along with the car. Car becomes a safety hazard due to poor visibility. Especially evident during reverse.

BACK OVER PREVENTION: WARNINGS

While reversing in this 2021 Tesla Model Y (software v12, 2025.14.1, Full Self-Driving Supervised), the vehicle’s ultrasonic sensors showed a wall directly behind on the display. However, the Tesla Vision camera system did not visually render the wall, and neither Automatic Emergency Braking (AEB) nor Obstacle-Aware Acceleration activated. The car reversed under driver input directly into the wall, causing a collision with property damage. The safety defect appears to be that the ultrasonic sensors, although still present and visually displayed, are no longer integrated into the collision avoidance systems after Tesla’s software updates activating Tesla Vision. As a result, the AEB and OAA systems seem to rely only on camera data, ignoring ultrasonic sensor input — leaving a dangerous blind spot in reverse. This problem affects safety because the driver receives no warning that AEB or OAA will not engage based on ultrasonic detection alone. Tesla’s updated owner manuals (2023.12) state that AEB is now designed to work in reverse, but in this case, the system failed. The issue has not yet been inspected by Tesla or a dealer but appears reproducible on vehicles with ultrasonic sensors running Tesla Vision software. This is likely a widespread defect affecting 2020–2022 Tesla Model 3, Y, S, and X vehicles equipped with ultrasonic sensors but updated via software. There were no warning lights or system alerts before the failure. I request NHTSA investigate whether Tesla’s software has disabled or failed to integrate ultrasonic sensor data into rear collision avoidance, creating an undisclosed safety risk for owners.

FORWARD COLLISION AVOIDANCE: WARNINGS

The front collision warning is too sensitive and reacts unnecessarily to many events that are not a risk for collision. In addition, the sound of the warning is too loud causing the driver to become unnecessarily startled and may cause possible loss of control of the vehicle.

BACK OVER PREVENTION: SENSING SYSTEM: CAMERA

Per the Tesla service team, there is a defect in the car computer which causes intermittent signal of the backup camera, failure of automatic emergency braking, and also Autopilot unavailability in a 2021 Tesla Model Y with less than 40k miles on it. This issue only occurred after a software update and affects key safety features such as blind spot warning proximity warnings. The Tesla service team said the only way to solve it was to replace the entire car computer and charged us $2,583 for their own product defect. The car did issue alerts to us saying that Autopilot and automatic emergency braking were unavailable, but did not detect issues with intermittent camera signal.

VISIBILITY/WIPER

In 2024 Tesla sent an over-the-air software update to my 2021 Model Y that gave us a month of free "full self driving." We did not ask for this. At the end of the 30 days, our cameras and GPS system failed. The Service Center said they had never seen this before despite many reports online posted by other Teslas owners. Tesla service said it was not fixable and recommended replacing computer at a cost to me of $2500. Now Tesla has posted a safety recall for this exact problem. They admit it was their fault and the recall states Tesla will replace the computer at no cost to the customer. However, they are only willing to fix the 2023-2025 models (those years are still under warranty). I feel that Tesla should fix all the model years that were affected. Tesla has again declined to fix my car. This is the recall website: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM

The windshield will fog up often due to moisture, which is made worse by activating the mechanism the Tesla model Y has for defogging, and rolling the windows down does little. This put my safety at risk when my visibility was compromised by this while driving on the highway, when I had to navigate and pull into the breakdown lane using teslas cameras. There were no warning lights, and this vehicle part has not yet been inspected. Since this issue has happened on residential streets to me before, I was able to avoid a crash, but I had little to no visibility, and it’s only a matter of time until this does result in a crash.

SEAT BELTS

I am writing to formally file a complaint against Tesla Motors regarding a serious safety issue involving defective seat belts in my vehicle. Despite my efforts to address this matter directly with Tesla, their response has been dismissive, prioritizing an out-of-pocket repair fee over a fundamental safety concern. Recently, my [XXX] son discovered that rear driver side seat belt does not latch onto the buckle. When I contacted Tesla to seek assistance in resolving this issue, I was informed I would need to pay out of pocket to replace the buckle because my warranty had expired as of January this year. During the replacement, the Tesla technician pointed out that the other 2 seat belt buckles in the back seat were also defective and would soon not function properly. The Tesla service center in Alhambra, CA was notified but they categorized it as a customer-pay repair. An expired warranty should not absolve Tesla of responsibility for a defect in a critical safety component. Seat belts are essential for driver and passenger protection, and any failure in their function could lead to serious injury or fatality. I am deeply concerned that Tesla does not seem to be taking this issue seriously. Instead of addressing the safety risk posed by the defective seat belts, their response has been to demand payment for a repair that should not be the driver's financial burden. Safety should always be the top priority, and I believe Tesla’s handling of this matter is unacceptable. I urge your office to investigate this issue further to ensure that Tesla is held accountable for addressing potential defects in their seat belts. If Tesla is unwilling to resolve this matter appropriately, I believe regulatory intervention is necessary to protect consumers from similar safety risks.

It took me and my 15 year old son 10 or so minutes to clear the snow behind the car. Then I started to salt the driveway behind the car and a snowplow driving by started honking. I looked up and the car was sliding down the driveway towards the road. Luckily it slowed and stopped, only slightly into the road and did not hit the snowplow, or anything else and I was able to get in and move it.

The pedestrian warning system and horn are speakers in newer Tesla's. The speaker is in the front right ahead of the wheel facing down towards the road. When it is raining or snowing, rain or snow get lodged into the speaker and it is completely inaudible. I stood 4 feet away from my vehicle and had someone honk the horn and couldn't hear anything at all. This is very dangerous. The pedestrian warning system is complexly inaudible also. Issue persists for approx. 2 days after rain. If it continues to rain for several days, the horn does not work the entire time. I have contacted Tesla support and they state there is nothing they can do to fix it since it is how it was designed.

Since March 2024, FSD has failed to function as designed. Tesla denied any problem with the vehicle until October 2024, when a manager told me it's a known issue with no available fix. The issue started with FSD not recognizing traffic signals. Meaning that regardless of whether a traffic light was green or red, the vehicle would treat it like an 4 way stop. It would come to a stop and then proceed through the intersection if it didn't detect immediate cars. This was dangerous and Tesla refused to acknowledge the problem for months. Since then the issue has evolved with FSD only engaging in certain situations (interstate driving). As of the most recent update, FSD won't engage at all.

When we tried to reverse, we could not see anything. When we tried to make a left or right turn, there were no sensors available to sense blind spots. When we tried to understand the speed limit or change lanes, the information was not available. Wipers were patchy in use Auto pilot also did not work. Warnings kept beeping while driving, but we could not turn it off, serving as a distraction to driver, but Tesla was unable to address the repair due to their mass recall of other cars (with similar issues).

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

This complaint addresses the recent changes made to the cruise control system in Tesla vehicles, as per NHTSA guidance in 2024. While the update aims to simplify the activation of enhanced cruise control, it introduces significant disadvantages and safety risks that need to be addressed. 1. Cruise Control Activation Update: NHTSA Guidance: In 2024, Tesla was required to modify the activation process for enhanced cruise control, allowing it to be engaged with a single pull when the option is selected. There are two options available: single pull and double pull. Advantages:  The update simplifies the process, enabling users to activate enhanced cruise control with a single pull, which is more convenient and user-friendly. Disadvantages:  When the enhanced cruise control is activated and the turn signal is engaged, the system automatically deactivates.  This deactivation causes the vehicle to stop maintaining its set speed, leading to a slowdown or complete stop. 2. Safety Risks: Driver Reaction:  The sudden deactivation of cruise control requires drivers to quickly move their feet back to the gas pedal to maintain speed.  This is particularly concerning when attempting to change lanes or merge into tight spaces, where maintaining speed is crucial for safety. Loss of Safety Features:  Upon deactivation of the enhanced cruise control, the vehicle no longer maintains a safe following distance, transferring full control back to the driver.  This abrupt transition means that the driver is left without the system's assistance to ensure safe driving and timely reactions, potentially increasing the risk of collisions. Increased Driver Workload:  Drivers must frequently reactivate cruise control after changing lanes, which demands additional effort and diverts attention from the road.  This constant need to manage the cruise control system can lead to driver distraction and increased cognitive load, potentially compromising road safety. 3.

BACK OVER PREVENTION: REARVIEW SYSTEM BRAKING

This report addresses concerns regarding recent safety updates in the Tesla Model Y, specifically focusing on the "Rear Cross Traffic Alert" and the blind spot warning system. These updates are intended to enhance driver awareness and prevent collisions. However, there are significant shortcomings in their current implementation that may compromise driver safety. 1. Rear Cross Traffic Alert: Intended Functionality: The "Rear Cross Traffic Alert" is designed to warn drivers of approaching vehicles from the side when reversing, thereby preventing potential collisions. Current Implementation: The system currently highlights a portion of the infotainment screen in red when a potential hazard is detected. There is no accompanying audible alert to notify the driver of the danger. Safety Concerns: Drivers are likely to be looking over their shoulder or at their mirrors while reversing, rather than at the infotainment screen. The lack of an audible alert means that drivers may not notice the visual warning, especially if their attention is directed away from the screen. This could lead to an increased risk of collision, as the visual cue alone may not be sufficient to capture the driver's attention. 2. Blind Spot Warning System: Intended Functionality: The blind spot warning system is designed to alert drivers of vehicles in their blind spot when the turn signal is activated, helping to prevent lane-change collisions. Current Implementation: Similar to the Rear Cross Traffic Alert, the system highlights the screen in red when a vehicle is detected in the blind spot. No audible warning is provided to alert the driver. Safety Concerns: In adverse weather conditions, such as rain, drivers may rely more heavily on blind spot warnings due to reduced visibility. Drivers typically turn their heads to check for vehicles, which means they may not see the screen's visual alert. Without an audible warning, drivers may inadvertently change lanes into an occupied space, increas
