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.
Consequence: If the valves do not properly close, additional brake pedal travel may be required to stop the vehicle, increasing the risk of a crash.
Remedy: 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. The recall began April 1, 2021. Owners may contact Ford customer service at 1-866-436-7332. Ford's number for this recall is 19S54.

Has your Ford been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. Recall repairs are free.
