Hyundai Santa Fe Sport shaking at traffic light due to spark plug power loss on Hyundai Santa Fe Sport

Some Hyundai Santa Fe Sport owners report experiencing shaking at traffic lights, which may be attributed to power loss related to faulty spark plugs. This shaking can indicate a misfiring engine, commonly caused by bad or dirty spark plugs that fail to provide proper ignition. Additionally, owners have noted that fouled spark plugs can lead to reduced acceleration and hesitation when pressing the gas pedal. If the check engine light is illuminated, it is recommended to use an OBDII scanner to retrieve trouble codes, which can aid in diagnosing spark plug-related problems. In older models, issues with the ignition system components, including spark plugs, coil packs, and plug wires, can also contribute to shaking and misfiring. To resolve these concerns, it is advisable for owners to have their spark plugs checked and potentially replaced.
