Anti-lock brake system (ABS) Malfunction Indicator Lamp (MIL) illuminated

What NHTSA is examining

The Office of Defects Investigation (ODI) received a petition on December 22, 2025, requesting a defect investigation into the hydraulic control unit (HCU) for the Anti-lock Braking System (ABS) on the MY 2010 Ford Fusion Hybrid. The petition alleges that an illuminated ABS 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, particularly on slippery road surfaces. A defect petition has been opened to evaluate the issue and determine whether to grant or deny the petition.The petition can be reviewed at NHTSA.gov under ODI number 11647929.
