The issue involves the brake hydraulic system and the fluid specified for my 2023 Hyundai Santa Fe Calligraphy. Hyundai’s owner specification requires SAE J1704 DOT-4 LV / ISO 4925 Class 6 brake fluid. During a brake-fluid exchange, an authorized Hyundai dealer installed BG 84032, which BG identifies as conventional DOT 4. BG sells a separate product, BG 84132, identified as Low Viscosity DOT 4 meeting ISO 4925 Class 6.  The original BG 84032 has since been correctly replaced by an independent repair facility and is not available for inspection. I have attached all materials I believe are relevant. Both BG product specifications are available from the BG website.  My safety concern is that conventional DOT 4 does not meet the Class 6 low-temperature viscosity requirement specified for this model and other high-volume Hyundai models, which could affect ABS/ESC hydraulic response under low-temperature, icy, or snowy conditions.  The Hyundai dealer’s repair order documents installation of BG 84032, consistent with the MOBIS part listing for the vehicle. An email exchange between the dealer and a Hyundai Motor Americas (HMA) parts advisor suggests a lack of understanding of the required fluid specification. HMA customer service twice confirmed to me the vehicle requires a 'DOT 4 LV' fluid.  There appears to be conflicting Hyundai information: the owner specification requires DOT-4 LV/Class 6; the reservoir cap states only 'DOT 4' and Hyundai/MOBIS service information simply lists conventional DOT 4.  In addition, a call to the Lithia Hyundai (Reno) parts department also resulted in a recommendation for conventional DOT 4, suggesting this may be systemic rather than an isolated dealer error.  No police or insurance inspection occurred. I am asking NHTSA to determine the extent to which this represents a broader safety-related service-information issue.","products":[{"type":"Vehicle","productYear":"2023","productMake":"HYUNDAI","productModel":"SANTA FE","manufacturer":"Hyundai Motor America"}]}]}
