2014 TESLA MODEL S

ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL

Tesla, Inc. (Tesla) is recalling certain 2012-2023 Model S, 2016-2024 Model X, 2017-2023 Model 3, 2019-2024 Model Y, and 2024 Cybertruck vehicles. 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.

SUSPENSION

Vehicle Information: 2014 Tesla Model S VIN: [XXX] Incident Date: [XXX] Component Affected: Suspension / Air Suspension / Ride Height Control Problem Description: On [XXX], while driving, my 2014 Tesla Model S suddenly raised itself to and/or beyond maximum ride height without any driver input. Immediately afterward, the front driver-side suspension collapsed completely, leaving the vehicle unsafe to operate. This appears to be an uncommanded overinflation event caused by Tesla’s suspension control system. It is not normal wear but a manufacturer-induced malfunction. If this failure had occurred at highway speeds, it could have caused catastrophic loss of control. The collapse of a suspension system without warning is a serious safety defect. Tesla’s service center in Moraine, OH, has refused to review the vehicle logs (which would confirm this sequence of failure) and has instead classified the incident as a standard part failure. As a result, Tesla is attempting to push full financial liability onto the owner instead of addressing what is clearly a safety-critical defect. Safety Concern: A sudden, uncommanded suspension height change followed by collapse could lead to total loss of vehicle control and a crash. This poses an ongoing risk to both Tesla drivers and the public. Requested Action: I am requesting that NHTSA investigate this failure mode as a safety defect in Tesla Model S vehicles and require Tesla to address these failures appropriately. Service Center Involved: Tesla Service Center 1927 W Dorothy Ln Moraine, OH 45439 Owner Information: [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN

Coolant ingress found on second Model S large drive unit in rear. After this leak destroyed my first vehicle, second was checked as a precaution and was found to have coolant leaking into drive unit as well.

UNKNOWN OR OTHER

the recirculation button takes 3 presses to engage/disengage or 1. sometimes 2. it's supposed to be an "intelligent" design. I'm sure there's software programming that determines when 2 presses are required vs 3 or 1 but to a driver it can be dangerous while focusing on the road. It should just be 1 press engages or disengages recirculation PERIOD just like other vehicles. Also, those buttons should be on the main page of the ipad screen. it shouldn't take opening 2-3 different pages on the screen to get to the recirculation button. Buttons that should be on the main page that you don't need to open several pages to get to: 1. recirculation button 2. AC button (it is a serious safety issue when trying to defrost on a humid day but it takes pressing several different buttons to get to the AC button that should just be out in the open like any other car. 3. suspension height (sometimes you need to quickly change for clearance and if distracted by opening several pages to get to the suspension button, it is a safety issue) All those buttons should be lined up on the far left edge of the screen closest to the driver and preferably towards the top. It's a serious safety issue to be distracted by fidgeting around on the screen to get to those buttons that are supposed to be "right there".

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

I was driving my car on the freeway on cruise control, when there was a sudden/automatic violent break of 65 MPH to 0 MPH. There was no car in front of me, and there was nothing above my car (no direction sign, no bridge, no FASTRAK billboard, nothing). This was a "phantom break" and it was violent and sudden. Tesla needs to fix this!

ELECTRICAL SYSTEM

My instrument cluster goes off while driving making it impossible to know my current speed. It also will cut off when i put it in park and the car will not move until it completely reboots. Sometimes it will just freeze and say the car is off and in park while the car is in Drive moving. One time the cluster showed that the car was in reverse but when i hit the accelerator, car moved forward. Cluster is constantly rebooting itself. 2014 Tesla models S 85. I have an attached video where all warning signs are illuminated,no speedometer and shows its in park while im driving
