Daimler AG is recalling about 85,000 Mercedes-Benz vehicles in the United States to prevent a loss of power steering fluid.

The government’s auto safety agency says in a posting to its Web site Monday that the recall involves Mercedes-Benz C-Class vehicles from the 2010 model year and Mercedes-Benz E-Class vehicles from the 2010-2011 model years.

The German automaker told the government that the loss of fluid could make it difficult to control the vehicle in a parking lot, where maximum power steering is required.

The recall is expected to begin this month.
