Transport Canada Recall - 2010170 - GENERAL MOTORS

On certain vehicles equipped with a 2.8L V6 engine, if low octane (regular) fuel is used in the vehicle instead of the required high octane (premium) fuel, as stated in the owner manual and on the fuel filler door, the combination of regular fuel usage and aggressive driving maneuvers may induce pre-ignition. If pre-ignition occurs, the driver will hear a pinging or knocking sound from the engine, and if the vehicle continues to be driven after the onset of this noise a connecting rod or piston may break, resulting in engine failure which would disable the vehicle, increasing the risk of a crash causing property damage, personal injury or death. Correction: Dealers will reprogram the engine control module.
