According to GM, if low octane fuel is used in the vehicle instead of the required high octane (premium) fuel and the driver performs “aggressive driving maneuvers”, pre-ignition issues might appear. The premium fuel use requirement is specified on the fuel filler door and in the vehicle’s owner manual.
When the pre-ignition occurs, the engine will produce a pinging or a knocking sound, which should alert the driver, who is supposed to stop the car.
However, if the vehicle continues to be driven consequent to the malfunction, a connecting rod or piston may break. This could result in engine damage, and may even lead to an engine failure, which would disable the vehicle and increase the risk of a crash.
The National Highway Safety Administration has identified 547 SRX Crossovers which could have this problem, with the vehicles being the first to be recalled. It is unknown if there will also be other vehicles involved in the campaign.
The company’s dealers will reprogram the engine control module to prevent the aforementioned events from taking place. The fixing will be done free of charge, with the campaign scheduled to debut by June 11.
