Loss of Motive Power

What NHTSA is examining

The Office of Defects Investigation (ODI) received a petition on August 5, 2026, requesting a defect investigation into the 2.0 Liter EcoBoost engine on model year 2015-2018 Ford Edge vehicles. The petition alleges that engine coolant intrusion results in a significant loss of engine power, accompanied by an "Engine Coolant Over Temperature" warning message. The petition further alleges that after the vehicle has sat and cooled down, the engine runs roughly and generates a check engine light for a cylinder misfire. This defect petition is being 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 11754989.
