American auto giant Toyota ordered dealers around the U.S. Tuesday to stop selling eight of their most popular vehicle models.

The move is part of Toyota's latest effort to deal with their accelerator pedal problems.

Initially, Toyota blamed their floor mats for the issue, but now says the problems are more severe.

"This action is necessary until a remedy is finalized," said Bob Carter, Toyota's group vice president and general manager.

The recall comes after many drivers reported cars accelerating by themselves. Several fatal accidents have been linked to the issue.

A Toyota official said Wednesday that although the suspect parts are made by a U.S. supplier, they can also be found in the automaker's European vehicles. The company is reviewing possible steps to take in Europe including a recall.

The U.S. recall includes the 2009-2010 RAV4, the 2009-2010 Corolla, the 2007-2010 Camry, the 2009-2010 Matrix hatchback, the 2005-2010 Avalon large sedan, the 2010 Highlander crossover, the 2007-2010 Tundra pickup and the 2008-2010 Sequoia large SUV.

Starting the first week of February, the company is also halting vehicle production at six North American car-assembly plants. Toyota says it is unsure how long the suspension will last.
