The National Highway Traffic Safety Administration has just began to investigate nearly 250,000 Ford Motor Company->ke31 vehicles. The cause of the problem is floor mats. The NHTSA has warned drivers not to use unsecured all-weather floor mats in their vehicles.

The investigation is taking a look at 2010 Ford Fusion and Mercury Milan vehicles, due to loose floor mats causing the accelerator pedal to become entrapped. The NHTSA warned drivers not to place these all-weather mats over top of current floor mats in the drivers side foot well.

Ford spokesperson Said Depp said the company was unaware of any injures of accidents because of the problem. "We do not recommend stacking floor mats in any vehicle from any automaker," Deep said to the Detroit News.

"All owners of these vehicles should ensure that any mat used is properly secured and never stacked," NHTSA said in a statement. "Any Ford 'all weather' optional floor mat should be placed in the driver's side foot well only after first unfastening and removing the standard, carpeted floor mat."

NHTSA said it had no reports of injuries, accidents or deaths.
