This notice sets forth the reasons for the denial of a defect petition, DP26-004, submitted by Mr. Richard De Leon (the Petitioner) to NHTSA (the Agency) by letter received December 22, 2025. The petition requests that the Agency initiate a safety defect investigation into the hydraulic control unit (HCU) for the Anti-lock Braking System (ABS) on the Model Year (MY) 2010 Ford Fusion Hybrid. The petition alleges that an illuminated ABS malfunction indicator lamp (MIL) is associated with a failure of the ABS HCU, resulting in ABS malfunction, loss of traction and electronic stability control functions, and reduced braking performance on slippery road surfaces. After conducting a technical review of the petition and other information, the Agency concluded that the issues raised by the petition do not warrant a new defect investigation. Accordingly, the Agency denied the petition.
