An incorrect font size is displayed on the instrument panel for the Brake, Park, and Antilock Brake System (ABS) warning lights. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 105, "Hydraulic and Electric Brake Systems" and 135, "Light Vehicle Brake Systems."

Risk: Warning lights with a smaller font size can make critical safety information on the instrument panel difficult to read, increasing the risk of a crash.

SEAT BELTS:FRONT:WARNING LIGHT/DEVICES

Tesla, Inc. (Tesla) is recalling certain 2012-2024 Model S, 2015-2024 Model X, 2017-2023 Model 3, and 2020-2023 Model Y vehicles. In the event of an unbelted driver, the seat belt warning light and audible chime may not activate as intended. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."

Risk: A seat belt warning system that fails to alert occupants of an unbelted seat belt can increase the risk of injury during a crash.

ELECTRICAL SYSTEM:ADAS:AUTONOMOUS/SELF DRIVING:SOFTWARE

Tesla, Inc. (Tesla) is recalling 2012-2023 Model S, 2016-2023 Model X, 2017-2023 Model 3, and 2020-2023 Model Y vehicles equipped with all versions of Autosteer leading up to the version(s) that contains the recall remedy. In certain circumstances when Autosteer is engaged, the prominence and scope of the feature's controls may not be sufficient to prevent driver misuse of the SAE Level 2 advanced driver-assistance feature.

Risk: In certain circumstances when Autosteer is engaged, and the driver does not maintain responsibility for vehicle operation and is unprepared to intervene as necessary or fails to recognize when Autosteer is canceled or not engaged, there may be an increased risk of a crash.

BACK OVER PREVENTION:SOFTWARE

Tesla, Inc. (Tesla) is recalling certain 2012-2018 Tesla Model S and 2016-2018 Model X vehicles with a center display equipped with a NVIDIA Tegra 3 processor and an 8GB eMMC NAND flash memory device. When the 8GB eMMC NAND flash memory device for the center display reaches lifetime wear, the eMMC controller will no longer be able to maintain the integrity of the filesystem, causing a failure in some of the center display functions.

Risk: The eMMC controller wear-out condition can cause the loss of the rearview camera display, defrost/defog control settings, and exterior turn signal lighting, reducing visibility and increasing the risk of a crash.

LATCHES/LOCKS/LINKAGES:HOOD:LATCH

Tesla, Inc. (Tesla) is recalling certain 2014-2021 Model S vehicles. The front trunk latch assembly may be misaligned, preventing the secondary hood latch from engaging. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 113, "Hood Latch System."

Risk: If the primary latch is inadvertently released and the secondary latch is not engaged, the hood could open unexpectedly, obstructing the driver's view and increasing the risk of a crash.

AIR BAGS:FRONTAL:PASSENGER SIDE:INFLATOR MODULE

Tesla, Inc. (Tesla) is recalling all 2014-2016 Model S vehicles equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these inflators may explode due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.

Risk: An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.

STEERING:ELECTRIC POWER ASSIST SYSTEM

Tesla, Inc. (Tesla) is recalling certain 2012-2016 Tesla Model S vehicles equipped with Bosch steering racks. The aluminum bolts that attach the power steering gear assist motor to the gear housing may corrode and fracture causing a reduction or complete loss of power steering assist.

Risk: Loss of power steering assist would require a higher steering effort, especially at lower speeds, which may increase the risk of a crash.

PARKING BRAKE

Tesla, Inc. (Tesla) is recalling certain 2016 Model S and Model X vehicles. The electric parking brake calipers have an internal gear that may be improperly manufactured, possibly resulting in the gear fracturing during parking brake application or release.

Risk: If the gear breaks during parking brake release, the vehicle will not be able to be moved. If the gear breaks during parking brake application, the parking brake may not adequately hold the vehicle, potentially resulting in the vehicle rolling, increasing the risk of a crash.

UNKNOWN OR OTHER

An investigation has been conducted into a persistent and widespread defect affecting the 2015 Tesla Model S and other early models equipped with the first-generation Media Control Unit (MCU1). This defect manifests as the physical degradation and spontaneous leakage of a sticky adhesive substance from the edges of the vehicle's central infotainment screen and instrument cluster. The leaking substance is not merely a cosmetic issue but presents a credible safety risk to vehicle occupants and the vehicle itself. The substance is a source of Volatile Organic Compounds (VOCs), a class of chemicals with a low boiling point that are known to off-gas into the ambient air, a problem exacerbated by high temperatures. Exposure to these compounds can lead to both acute and long-term health consequences, including respiratory irritation, headaches, and in some cases, serious chronic illnesses. Furthermore, the presence of flammable solvents and components within the adhesive, combined with the heat generated by the electronic components of the MCU1, creates a potential fire risk. This report is submitted to the NHTSA to provide a detailed, technical analysis of the adhesive degradation and leakage in the 2015 Tesla Model S. The purpose is to formally document this specific defect as a safety issue that warrants regulatory action, separate from but related to the manufacturer's previous recall for the MCU1's eMMC memory wear. It is essential to demonstrate that the adhesive failure is not a cosmetic inconvenience but a distinct material failure with serious implications for occupant health and vehicle safety. This report aims to provide the necessary evidence and analysis to support a formal investigation and a comprehensive recall that fully addresses this physical defect.

LANE DEPARTURE: BLIND SPOT DETECTION

What happened? While driving my 2015 Tesla Model S, the main touchscreen (MCU) began intermittently going black, disabling access to essential vehicle controls, navigation, climate settings, and rear-view camera display. At times when the MCU was functioning, the rear-view camera feed would still display a black screen upon shifting into Reverse, leaving me without any rear visibility. Component or system that failed: Media Control Unit (MCU1) / eMMC memory failure Rear-view camera and/or associated wiring harness Safety risk: The intermittent blackouts of the MCU and loss of rear camera feed created significant safety hazards, especially when reversing or attempting to adjust driving settings while in motion. The loss of rear visibility increased the risk of collision with pedestrians, cyclists, or obstacles. The MCU failure also limited access to defrost/defog controls and turn signal audio feedback. Problem reproduction and confirmation: Tesla Service has confirmed both the MCU1 hardware failure and the rear-view camera malfunction. The problems occurred repeatedly before being inspected. Inspection: The vehicle has been inspected by Tesla Service Center technicians, who diagnosed both the failing MCU1 and the defective rear-view camera. Warning messages or symptoms prior to failure: For MCU: slow system performance, frozen screen, then intermittent complete blackouts while driving. For rear-view camera: black or distorted camera feed when in Reverse, even when the MCU display was otherwise operational. These issues began occurring in June 2025 and became progressively worse until Tesla inspection on July 6, 2025.

STEERING

A few times the steering control has shut off while I am driving. Steering failure lasts a few seconds and then returns to normal function. The car makes a VERY loud alarm sound when the steering is inoperable. I have not seen any failure messages on the screen or in the Service menu. I took the car to Tesla for service yesterday. They did some sort of remote scan of the fault codes and told me that there is nothing wrong. They told me to continue to drive the car and record when the steering stops working again. This sounds like ridiculously bad advice to me. While the steering control has always returned in just a few seconds, that does not mean that it will in any future failure. I am concerned about driving this car. Tesla wants $275 an hour to investigate the problem, which also seems ridiculous to me. I have seen that there has been a recall for similar problems in newer Tesla Model S vehicles. It seems logical to me that these problems may be related and deserve additional investigation ... at Tesla's expense.

ELECTRICAL SYSTEM

Many air bubbles are appearing towards the bottom of the instrument panel on our 2015 Tesla Model S. This started a couple of weeks ago and the bubbles are increasing in size and number and they are moving upwards. The bubbles don’t presently obscure important driver information such as the transmission mode (drive, park, reverse, neutral), remaining battery range (e.g. 80%), car speed (mph), parking sensor distance, brake light status, car door open, frunk open, tailgate open, time, outdoor temperature, car lights on/off, warning lights, etc. However, the bubbles likely will do so in the future. Much of this information is vital for safe driving (e.g. transmission mode, speed (mph), remaining battery range, brake light status, and warning lights). As such this display should be replaced by Tesla at nominal or no charge to the owner. According to the internet, the cause of these air bubbles is a failed seal around the instrument cluster that allows a lamination fluid between the LCD display and the cover glass to leak out. It is a very common problem with older Model S’s. It is a critical safety problem.

POWER TRAIN

Large drive unit that has previously been replaced by Tesla failed due to coolant ingress leaking through rotor seal. Known issue per 3rd party technicians.

UNKNOWN OR OTHER

Hi, my trunk won't open when I press the button. This is the second occurrence that jas happend. When inside the trunk compartment the emergency cable to open the trunk is also not responsive and can not open the trunk. I think this is a big safety concern as the safety cord is there for a reason and in both cases id did not worked.

ENGINE

Steering: While driving today (7/5/2025), all of a sudden and without warning, "driver assist" (power steering) became disabled. Steering wheel immediately became heavy in the sense that it was extremely difficult to turn. Motor: Also, on 02/22/2024, while driving on the freeway at freeway speed, all of a sudden and without warning, the rear LDU (large drive unit) failed and the car became inoperable. At that time, the car had approximately 45k miles on it.

STRUCTURE:BODY:DOOR:HANDLE:EXTERIOR

I parked my 2015 Tesla Model S and found the rear door on the passenger side would not open from the outside even though the door handle was extended. This is a safety concern as we could not open the door to remove our pet dog from the car. It would also not be possible to open the door from the outside to remove a child in a car seat next to the door or an elderly or disabled person sitting next to the door who is unable to open the door from the inside. This could be life threatening in the case of a car crash. It is a major safety defect that should be repaired at no cost by Tesla for the entire lifespan of the car. The problem persists and is reproducible.

STEERING

While driving and mid-turn, 2 alerts were announced (park assist not available; steer assist reduced) and I immediately lost the ability to turn the steering wheel (it was 100% stiff) mid turn and was almost t-boned by a vehicle in on-coming traffic. I was able to make the turn widely and pull car to the side while blocking the only lane of traffic. I had ZERO warning and ZERO ability to turn the wheel even into a simple driveway. There was a parking lot near and I couldn't turn the wheel just to turn into it. This almost caused a huge accident which I could have been killed in. Luckily my children were not in the car. If the car can just stop working with no warning, it is not safe to drive in my opinion.

STRUCTURE:BODY

Safety concern related to the tail lights and trunk lid lights on a tesla model s. I have had to replace both right and left turn lights and the trunk brake lights on multiple occasions due to water intrusion into the light housings. Water seepage over time or after heavy rains starts shorting the LEDs, thus causing safety concerns due to non-functioning tail lights. The vehicle has not been in an accident. It was purchased from a tesla "dealership" and they stated that there were no accidents. The car history report also indicates that the car has not been in an accident. There has been one attempted repair which added two drains to the trunk lid but the repair did not remedied the seepage into the light housing. There are reports online relating to water seepage into the light housings so its not just my car.
