Ford Motor has agreed to fix sticky throttles on nearly 468,000 Ford Taurus and Mercury Sable sedans.
Because of the company's decision, U.S. safety regulators have closed an investigation into the problem.
Last fall, the National Highway Traffic Safety Administration began investigating cars from the 2000 through 2003 model years. The safety agency and Ford received 100 complaints about throttles on cars with 3-Liter, four-valve Duratec V-6 engines.
The agency says Ford agreed to a "customer satisfaction campaign" and will fix problems for free.
