Chevrolet SSR knocking noise with wrench symbol illuminated, issue not resolved on Chevrolet SSR

Some Chevrolet SSR owners report experiencing a knocking noise accompanied by an illuminated wrench symbol, which may indicate various underlying issues. These owners have noted that the knocking sound could stem from interior noises like rubbing objects, as well as exterior sources such as worn brake pads or tires. Additionally, noises from under the hood, including a slipped belt or a worn alternator, may contribute to the problem. It is crucial for owners to address this issue promptly to prevent further damage to their vehicles. Many have found it beneficial to have a professional mechanic inspect their SSR to diagnose the specific cause of the knocking noise and to refrain from running the vehicle until it has been checked, as starting it could exacerbate the damage. Some owners also report checking for trouble codes with an OBD-II scanner to identify any engine performance issues. In certain cases, an illuminated check engine light may accompany the knocking, serving as a warning sign, while a drop in fuel efficiency could indicate inefficient combustion related to the knocking. If the issue persists, further investigation into potential causes like bearing damage or other mechanical issues specific to the Chevrolet SSR may be necessary. Promptly addressing engine knocking is essential for maintaining the vehicle's performance and preventing additional damage.
