  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.

  Remedy: Tesla began releasing an over-the-air (OTA) software update, free of charge. Owners may contact Tesla customer service at 1-877-798-3752. Tesla's number for this recall is SB-24-00-003.

  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.

  Remedy: Tesla will release an over-the-air (OTA) software update, free of charge. Owner notification letters were mailed February 10, 2024. Owners may contact Tesla customer service at 1-877-798-3752. Tesla's number for this recall is SB-23-00-008.

   This complaint covers a 13-month continuous chain of severe electrical system failures stemming from a deficient federal safety recall remedy on my vehicle's Media Control Unit (MCU) architecture. Tesla's corporate policy has been to replace only the isolated center screen explicitly tracked by the recall while leaving connected legacy components intact on mismatched architecture. This creates an uneven electrical strain loop that has systematically destroyed my vehicle’s…

   On 6/11/26, around 2:10 pm, when i was slowly pulling over to park on a road side, the car suddenly rushed forward unexpectedly. It was so powerful, at the time I could only hear the panic reactions from the two passengers and sense the imminent collision with the parked bmw in the front of several car length away. Right before the collision i steered the wheel to the right to avoid the bmw and my car came to violent halt less than a foot next to the bmw. I came out of my…

   I own a 2016 Model S P100D equipped with the Large Drive Unit (LDU). The component that fails is the rotor coolant seal in the rear drive unit motor. Coolant leaks internally into the motor and inverter, causing bearing wear, corrosion, isolation faults, and eventual complete drive unit failure. The affected drive units are still installed and available for inspection upon request. This defect puts my safety and the safety of others at risk because it can cause sudden loss…

   The rear Large Drive Unit (LDU) has coolant intrusion due to a known design defect in the internal rotor seal. Coolant from the stator cooling system is leaking past the seal into the motor, degrading the winding insulation. An independent inspection by The Electrified Garage (Orlando, FL) on 04/08/2026 confirmed moisture at the rotor sensor (yellow condition) and degraded insulation resistance measured at 3.0 megohms (should be hundreds of megohms on a healthy unit). The…

   My 2016 Tesla Model S (45,500 miles) is experiencing a complete failure of the Media Control Unit (MCU1), resulting in a total loss of the rearview camera display and defrost/defogging controls. This is a critical safety hazard. The unit was previously replaced by Tesla in 2021 under NHTSA Recall 21V-035. However, this replacement part has failed again after only a few years of low-mileage use. Tesla Service is refusing to provide a free repair or a goodwill discount for an…

   While driving on the freeway in the fast lane at 75 MPH I80W, the car began a loud humming sound that came from the rear. My passenger and I noted that it was significant sound that we took a video to record the sound. I was the driver and I noticed that the sound increased as I accelerated. Then without any warning the car began to decelerate and no longer accelerated. The car slowed considerably to 35 MPH and it became a major safety issue because I had to cross all lanes…

   I am writing to formally report a recall-related safety defect that occurred after the eMMC recall service on my vehicle’s Media Control Unit (MCU). Following the recall, the display adhesive began to leak and the screen started separating from its frame. The adhesive continues to drip onto the dashboard and the display shows signs of delamination. This is a safety issue that directly affects driver visibility and may result in electrical contamination inside the MCU. Under…

    The center touchscreen in my Tesla Model S developed a yellow discoloration and later began leaking a sticky fluid from the edges of the display. This fluid appears to be seeping from inside the screen and emits a noticeable odor. The touchscreen is the primary interface for controlling most of the vehicle’s safety-critical systems, including the backup camera, gear selection, climate control, lights, and driver assistance settings. The leak causes visible streaking and…
