GENERAL MOTORS issued a recall on the STS model

Certain all wheel drive vehicles equipped with a 3.6L engine did not have the torque monitoring functions of the electronic throttle control (ETC) enabled during vehicle assembly. These functions can limit engine speed and torque if unusual engine control module (ECM) hardware or software failures occur. Without these functions enabled, a persistent ECM failure could result in a throttle opening greater than commanded by the driver which could result in a crash. Correction: Dealers will reprogram the ECM.
