Toyota said on Tuesday it will recall some 3.8 million vehicles, including the Toyota Prius, because of the risk a floormat could keep the accelerator pedal forced down. As an immediate remedy, the Japanese automaker urged drivers of a range of recent models to remove driver’s-side floor mats until it could issue a recall in consultation with federal safety regulators.

The safety recall would be the largest ever US recall for Toyota. The recall will cover recent versions of the Prius, as well as Camry and Avalon sedans, the Tacoma and Tundra pickup trucks and luxury Lexus models, the IS250 and the IS350 as well as the ES350.
