Summary
Ford Motor Company (Ford) is recalling certain 2006-2010 Ford Fusion, Mercury Milan, Lincoln Zephyr and MKZ vehicles. The valves within the ABS Hydraulic Control Units (HCU) may react with brake fluids containing specific corrosion preventative additives. This reaction may cause the valves to not close properly.
Actions
Ford will notify owners, and dealers will flush the brake system with DOT 4 fluid and install a new brake fluid reservoir cap. In addition, the HCU will be tested to detect a possible stuck valve condition, replacing the HCU as necessary. All services will be performed free of charge. Owners will be notified of the safety risk with an interim letter on January 13, 2020. A second notice will be sent once parts are available, expected to be late in the first quarter of 2020. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 19S54.
