The Hydraulic Control Unit (HCUs) in the 2009 Ford Escape malfunctioned resulting in the brake pedal losing resistance. The brake pedal needed to be pushed all the way to the floorboard with aggressive force to stop the vehicle. This issue may have resulted in an interstate accident that put the driver at extreme risk. The vehicle crashed into the vehicle in front of the driver due to a delay in stopping from the malfunctioning of the HCU. There were no warning lights that were triggered to alert an issue with the unit. The repair shop that repaired the vehicle warned the driver that the brakes were not working properly and may have caused to the accident. Due to Ford backlogs on parts from COVID-19 delays, I discovered that 180 HCUs are currently on back order in the United States. Additionally, four Ford vehicles in the Greater New Orleans area are waiting for ACUs due to the same issue of the brakes not gripping until the pedal reaches the floor. Multiple sources online are warning of a similar issue from malfunctioning HCUs and ACUs. After learning this information, I filed a complaint with the Ford Corporate office but have not heard anything regarding the integrity of the part. However, when I dropped off the vehicle at the Lamarque Ford Dealership in Kenner Louisiana, I was told the vehicle was undrivable due to the malfunctioning of the HCU. The vehicle is available for inspection at the Lamarque Ford Dealership located at 3101 Williams Blvd Suite F, Kenner, LA
