Toyota has been subpoenaed again by a grand jury, this time for documents related to steering relay rods. A probe was launched when the National Highway Traffic Safety Administration (NHTSA) received documents indicating that Toyota had potentially misled the government in 2005 over problems with steering linkages in its 1989-95 4Runner and the 1993-98 T100 vehicles. The subpoena, issued June 29, requests documents related to “defective, broken and/or fractured steering relay rods of Toyota vehicles,” Toyota said in a filing with the Securities and Exchange Commission.

In February, the same federal grand jury subpoenaed Toyota for information related to unintended acceleration in its vehicles as well as braking systems in the Prius hybrid. Toyota has also received subpoenas related to sudden acceleration from the SEC and the attorney general of Michigan. Toyota did not disclose which vehicles or model years were targeted by the latest subpoena.
