Toyota Motor Corp late on Wednesday said it is expanding a recall of its cars and trucks by another 1.1 million vehicles to address the risk of accelerator pedals becoming dangerously stuck.

The recall involves 2009-2010 model year Corolla, Venza, Matrix vehicles and the 2008-2010 Highlander, as well as the 2009-2010 Pontiac Vibe. The Vibe had been assembled at a plant in California that Toyota had operated jointly with GM.

Toyota told federal officials of the expanded recall on Wednesday.

It is the second high-profile safety action in less than a week for the automaker.

Last week, Toyota recalled 2.3 million vehicles that it said may have a faulty accelerator pedal that sticks.

Last year, Toyota said it was recalling more than 4 million vehicles for what it then said were safety risks linked to improperly placed floormats.

In November, after the issue was investigated by the U.S. National Highway Traffic Safety Administration, Toyota said it would also modify or replace accelerator pedals as well.

The total number of recalled Toyotas in 2009 and 2010 now stands at 5.9 million. There are some models involved in last week's as well as last year's recall.

In a letter to the NHTSA on Wednesday, Toyota said its plan is to modify or replace accelerator pedals. Modifying vehicle floors also will be considered on some models, Toyota said.

Initially, dealers will be instructed on how to reshape the accelerator pedal for the repair, Toyota's letter to U.S. safety regulators said.

As replacement parts...become available, they will be made available to the dealers, Toyota said.
