Transportation Secretary Ray LaHood is telling owners of recalled Toyotas to stop driving the vehicles and get them fixed.

LaHood's warning came Wednesday in testimony before a House Appropriations subcommittee on transportation. LaHood says his advice to owners is to "stop driving it. Take it to a Toyota dealer because they believe they have a fix for it."

Toyota's most recent recall in the United States affects 2.3 million vehicles with the potential for sticking gas pedals.

LaHood told reporters earlier in the day that Toyota owners should contact their dealer immediately and "exercise caution until repairs can be made."
