Toyota announced on Thursday to recall its 2.3 million vehicles in the United States to fix problems with accelerator pedals.

Our investigation indicates that there is a possibility that certain accelerator pedal mechanisms may, in rare instances, mechanically stick in a partially depressed position or return slowly to the idle position, Toyota USA group vice president Irv Miller said in a statement.

The announcement follows an earlier and separate recall of 4.2 million vehicles to correct a problem in which the pedals could become stuck under loose floor mats.

This new recall is to correct a situation in which the gas pedal could stick without the presence of a floor mat.

Below is the list of affected vehicles:

-RAV4 2009-2010 models

-Corolla 2009-2010 models

-Matrix 2009-2010 models

-Avalon 2005-2010 models

-Camry 2007-2010 models

-Highlander 2010 model

-Tundra 2007-2010 models
