More than two million Toyota cars in the US are being recalled following concerns that a glitch in the pedal mechanism could potentially cause the accelerators to get stuck.
The manufacturer said that the problem could occur in rare cases where the pedal mechanism wears down, making it more difficult to press the accelerator or cause it to jam.
Just months ago similar fears over pedals getting wedged under floor mats had forced the car maker to recall nearly 4.2 million vehicles.
Models affected this time include the 2009-2010 RAV4, the 2009-2010 Corolla, the 2009-2010 Matrix, the 2005-2010 Avalon, the 2007-2010 Camry, the 2010 Highlander, the 2007-2010 Tundra and the 2008-2010 Sequoia.
Avalon, Camry and Tundra models that constitute around 1.7 million of the cars were also affected in the earlier recall.
Toyota said it was working to resolve the problem which appeared to be linked to a potential build up of condensation on the accelerator system's sliding surfaces which move the pedal up or down while driving.
The US agency responsible for traffic safety said it was a serious issue and welcomed Toyota's "immediate action to address it".
