NHTSA Complaint #11683749 — 2015 TESLA MODEL S

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.
