Problem overview

Some Chevrolet Corvette owners report experiencing cruise control malfunctions, including uncontrollable acceleration that can reach speeds of 100 mph and failure to shut off. These issues may stem from malfunctioning throttle sensors that cause erratic acceleration. Additionally, an overly sensitive brake or clutch switch could prevent the cruise control from disengaging properly. Some owners have noted that a short pulse of voltage or a malfunctioning relay or servo motor may also lead to unexpected acceleration. Furthermore, failure of the check valve, which maintains vacuum for the A/C controls and cruise function during acceleration, can contribute to these problems. Lastly, issues with connectors related to the Stop Lamp switches, cruise control position switch, and cruise control release switch may require cleaning and inspection to resolve cruise control difficulties. It is crucial for owners to address these potential causes systematically to ensure the safe operation of their vehicle.
