GMC Canyon cruise control intermittently drops speed suddenly, posing safety risk on highway on GMC Canyon

Some GMC Canyon owners report experiencing intermittent drops in cruise control speed while driving on the highway, which can pose a significant safety risk. This issue may arise from accidentally hitting the cancel button on the steering wheel, leading to unexpected deactivation of the cruise control. Additionally, entering low-speed zones where cruise control is not permitted can result in sudden speed reductions. Problems with the vehicle speed sensor or wiring harness can disrupt proper signal transmission, affecting the speedometer and causing further cruise control complications. Furthermore, a blown fuse that interrupts power to critical components, such as the cruise control switch and the Speed Sensor (VSS), may also lead to system malfunctions. To mitigate these risks, it is recommended that owners have their cruise control systems thoroughly inspected and repaired by a certified mechanic, along with regular maintenance to address any underlying issues promptly.
