NHTSA's summary
As NHTSA's Office of Defects Investigation wrote it for Defect Petition DP26-004.
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.

What an NHTSA investigation is
NHTSA's Office of Defects Investigation (ODI) looks into possible safety defects in vehicles and equipment, often after owner complaints. An investigation usually starts as a Preliminary Evaluation, or as a Recall Query when it concerns whether an existing recall covers the right vehicles or fixes the problem, and ODI can upgrade it to a more detailed Engineering Analysis. A Defect Petition asks NHTSA to open an investigation, and Audit and Equipment Queries are administrative investigations into whether companies complied with federal vehicle safety requirements, such as reporting, recall and certification rules.
An open investigation is not a finding that a safety defect exists, and NHTSA can close one without a recall.
