SYSTEM_COMPONENT
ENGINE AND ENGINE COOLING
EVENT_SUMMARY
Your vehicle's engine and cooling system has a specific requirement: you should use high-octane fuel. Using low-octane fuel and driving aggressively can cause a problem called pre-ignition, which makes the engine produce a knocking or pinging sound.
RISK_ASSESSMENT
If you continue to drive your vehicle after hearing this sound, there's a risk that a connecting rod or piston could break, causing engine damage or even complete engine failure, making your vehicle inoperable and increasing the risk of a crash.
RESOLUTION_PROTOCOL
You'll need to take your vehicle to a dealership, where they will reprogram the engine control module for free. This will fix the issue and ensure your vehicle runs safely. The recall is expected to start on or before June 11, 2010.
