Reflectors in the low-beam lights on the 2013 Fusions can become hazy over time and reduce the brightness.
Ford will replace the headlights for free to fix the problem. Owners will get notices in the mail starting this week.
Ford spokesman Said Deep said the problem was discovered by Ford's internal testing and was caused by improper manufacturing of the headlamp by a parts supply company. He said the recalls show that Ford will take action to correct safety problems as soon as it finds them.
Two weeks ago Ford recalled new Fusions and Escape SUVs with 1.6-liter turbocharged engines because they can overheat, leak fluids and catch fire. That recall affects 89,000 vehicles in North America.
The company said it had 13 reports of fires in those vehicles, and it told owners to stop driving them and use free loaner cars from dealers until the problem is fixed.
So far, the company hasn't figured out what caused the fires.
The 1.6-liter engines are used in the Focus and Mondeo sedans and Galaxy minivan in Europe.
