Problem overview

Some Chevrolet Malibu owners report experiencing issues with the 'Service Stabilitrak' warning and power loss, which may be linked to loose intake manifold bolts. These loose bolts can lead to a vacuum leak, negatively impacting the air-fuel mixture and triggering the 'Reduced Engine Power' warning. It is essential for owners to inspect the intake manifold bolts for tightness and proper sealing, as tightening them to the manufacturer's specifications can prevent further performance issues. Addressing this problem promptly can help restore optimal engine performance and avoid potential damage to the vehicle.
