The rear underbody air conditioning (AC) lines and their supporting structural mounting brackets have failed due to severe corrosion. Specifically, a heavy steel mounting bracket has rusted excessively, causing localized galvanic corrosion at the point of contact with the adjacent aluminum AC lines. This structural and material failure caused the aluminum line to erode, crack, and leak high-pressure chemical refrigerant into the environment. The vehicle, failed components, and detailed photographic evidence of the galvanic corrosion and rusted bracket are fully available for inspection upon request. 2. The failure presents multiple safety and health hazards: \u2022Environmental and Inhalation Hazard: The high-pressure leak of mobile air conditioning refrigerant (R-1234yf or R-134a) releases a hazardous chemical compound directly beneath the cabin. \u2022Defrost and Visibility Failure: The rapid loss of system pressure completely disables the vehicle\u2019s climate control and window defrosting/demisting capabilities, severely compromising driver visibility during inclement or humid weather. \u2022Structural Degradation: The severe rust and erosion of the underbody mounting bracket mean structural components are failing prematurely on a 2021 model, creating a risk of loose or dragging underbody debris at highway speeds. 3. The physical failure (loss of refrigerant and severe physical corrosion) has been visually confirmed. However, the Toyota dealership service center actively refused to document the cause. However, photographic evidence clearly reveals the distinct, localized galvanic corrosion occurring exactly where the rusted steel bracket contacts the aluminum line. Further, Toyota\u2019s highlander model had this same problem which was addressed through T-SB-0021-26. 4. The vehicle was inspected by an authorized Toyota dealership which acknowledged the leak but refused to provide a written technical breakdown. 5. Rust, corrosion, and loss of cooling ability.","products":[{"type":"Vehicle","productYear":"2021","productMake":"TOYOTA","productModel":"SIENNA HYBRID","manufacturer":"Toyota Motor Corporation"}]}]}
