Last week, the Wall Street Journal reported that the U.S. Department of Transportation found that sudden acceleration in Toyotas, which led to a massive recall, was actually the result of driver error. While acknowledging that floor mats were defective, the DoT found that most sudden acceleration incidents involved drivers mistakenly jamming on the accelerator rather than the brake.

Lest Toyota breathe a sigh of relief, the Washington Post reports that a federal grand jury issued subpoenas to the automaker for information about potentially defective steering relay rods. The steering relay rods relate to 4Runner SUVs, T100 pickups, and other pickups, and can allegedly wear out, causing drivers to lose control of their vehicles.
